Product Description

LYMC Supply Customized Professional Machining Steel Spur Gear For High Industrial Slew Gear

There are many types of gears such as spur gears, helical gears, bevel gears, worm gears, gear rack, etc. These can be broadly classified by looking at the positions of axes such as parallel shafts, intersecting shafts and non-intersecting shafts.

It is necessary to accurately understand the differences among gear types to accomplish necessary force transmission in mechanical designs. Even after choosing the general type, it is important to consider factors such as: dimensions (module, number of teeth, helix angle, face width, etc.), standard of precision grade (ISO, AGMA, DIN), need for teeth grinding and/or heat treating, allowable torque and efficiency, etc.

Spur Gear

Gears having cylindrical pitch surfaces are called cylindrical gears. Spur gears belong to the parallel shaft gear group and are cylindrical gears with a tooth line which is straight and parallel to the shaft. Spur gears are the most widely used gears that can achieve high accuracy with relatively easy production processes. They have the characteristic of having no load in the axial direction (thrust load). The larger of the meshing pair is called the gear and smaller is called the pinion.

 

Helical Gear
Helical gears are used with parallel shafts similar to spur gears and are cylindrical gears with winding tooth lines. They have better teeth meshing than spur gears and have superior quietness and can transmit higher loads, making them suitable for high speed applications. When using helical gears, they create thrust force in the axial direction, necessitating the use of thrust bearings. Helical gears come with right hand and left hand twist requiring opposite hand gears for a meshing pair.

Gear Rack

Same sized and shaped teeth cut at equal distances along a flat surface or a straight rod is called a gear rack. A gear rack is a cylindrical gear with the radius of the pitch cylinder being infinite. By meshing with a cylindrical gear pinion, it converts rotational motion into linear motion. Gear racks can be broadly divided into straight tooth racks and helical tooth racks, but both have straight tooth lines. By machining the ends of gear racks, it is possible to connect gear racks end to end.

 

 

Bevel Gear

Bevel gears have a cone shaped appearance and are used to transmit force between 2 shafts which intersect at 1 point (intersecting shafts). A bevel gear has a cone as its pitch surface and its teeth are cut along the cone. Kinds of bevel gears include straight bevel gears, helical bevel gears, spiral bevel gears, miter gears, angular bevel gears, CHINAMFG gears, zerol bevel gears and hypoid gears.

 

Screw Gear

Screw gears are a pair of same hand helical gears with the twist angle of 45° on non-parallel, non-intersecting shafts. Because the tooth contact is a point, their load carrying capacity is low and they are not suitable for large power transmission. Since power is transmitted by the sliding of the tooth surfaces, it is necessary to pay attention to lubrication when using screw gears.

 

Worm Gear

A screw shape cut on a shaft is the worm, the mating gear is the worm wheel, and together on non-intersecting shafts is called a worm gear. Worms and worm wheels are not limited to cylindrical shapes. There is the hour-glass type which can increase the contact ratio, but production becomes more difficult. Due to the sliding contact of the gear surfaces, it is necessary to reduce friction. For this reason, generally a hard material is used for the worm, and a soft material is used for worm wheel. Even though the efficiency is low due to the sliding contact, the rotation is smooth and quiet. When the lead angle of the worm is small, it creates a self-locking feature.

 

 

Internal gear

Internal gears have teeth cut on the inside of cylinders or cones and are paired with external gears. The main use of internal gears are for planetary gear drives and gear type shaft couplings. There are limitations in the number of teeth differences between internal and external gears due to involute interference, trochoid interference and trimming problems. The rotational directions of the internal and external gears in mesh are the same while they are opposite when 2 external gears are in mesh.

Can gear pumps be used in hydraulic systems?

Yes, gear pumps can be used in hydraulic systems. Here’s a detailed explanation:

1. Positive Displacement Operation:

Gear pumps operate on the principle of positive displacement, which makes them suitable for hydraulic applications. In hydraulic systems, a pump is required to deliver a consistent flow of fluid to actuate various components such as cylinders or motors. Gear pumps provide a steady and predictable flow rate, ensuring reliable operation of hydraulic systems.

2. Compact and Lightweight:

Gear pumps are often compact and lightweight compared to other types of hydraulic pumps. This makes them suitable for applications where space is limited or weight needs to be minimized. Gear pumps can be easily incorporated into hydraulic systems without adding excessive bulk or weight.

3. Cost-Effective:

Gear pumps are generally more cost-effective compared to other types of hydraulic pumps. They have a simple design with fewer components, which makes them easier to manufacture and maintain. This cost-effectiveness makes gear pumps a popular choice for a wide range of hydraulic applications.

4. Reliability:

Gear pumps are known for their reliability and durability. They have a robust construction with fewer moving parts, which reduces the chances of mechanical failure. Gear pumps can withstand high pressures and provide consistent performance over a long service life, making them well-suited for demanding hydraulic systems.

5. Viscosity Range:

Hydraulic systems may involve fluids with varying viscosities. Gear pumps are capable of handling a wide range of fluid viscosities, from low-viscosity hydraulic oils to more viscous fluids. The positive displacement action of gear pumps ensures a consistent flow rate regardless of the fluid viscosity, allowing them to adapt to different hydraulic fluid requirements.

6. Limitations:

While gear pumps offer several advantages, they also have some limitations in hydraulic systems. Gear pumps are generally not suitable for high-pressure applications where more precise flow control is required. They may produce higher levels of noise and have lower overall efficiency compared to some other types of hydraulic pumps.

In summary, gear pumps can be effectively used in hydraulic systems due to their positive displacement operation, compactness, cost-effectiveness, reliability, and ability to handle a range of fluid viscosities. However, for specific high-pressure or precision flow control requirements, alternative hydraulic pump technologies may be more suitable.

What is the significance of gear pump size and construction materials?

The size and construction materials of a gear pump play a significant role in its performance, durability, and suitability for specific applications. Here’s a detailed explanation:

1. Size:

The size of a gear pump refers to its physical dimensions, including the overall dimensions, shaft diameter, and gear dimensions. The size of a gear pump is important for the following reasons:

  • Flow Rate and Pressure: The size of the pump affects its flow rate and pressure capabilities. Larger gear pumps generally have higher flow rates and can handle higher pressures, while smaller gear pumps are suitable for lower flow rate and pressure requirements. Selecting the appropriate pump size ensures that it can meet the specific demands of the application.
  • Space Constraints: The physical size of the pump is crucial when space is limited. In compact installations or applications with restricted space, smaller gear pumps are preferred to optimize the use of available space.
  • System Integration: The size of the gear pump needs to align with the overall system design and integration. It should fit seamlessly into the system, considering factors such as mounting options, piping connections, and available space for maintenance and repairs.

2. Construction Materials:

The choice of construction materials for a gear pump is important for several reasons:

  • Chemical Compatibility: Different fluids have varying chemical properties, and certain fluids may be corrosive or reactive with certain materials. Selecting appropriate construction materials ensures compatibility with the fluid being pumped, preventing chemical reactions, degradation, or contamination of the fluid and the pump itself.
  • Mechanical Strength: Construction materials determine the mechanical strength and durability of the pump. The materials should be able to withstand the operating conditions, including pressure, temperature, and mechanical stresses, without deformation, fatigue, or failure. Common materials used for gear pump construction include cast iron, stainless steel, bronze, and specialized alloys.
  • Viscosity Handling: The construction materials can impact the pump’s ability to handle fluids with different viscosities. Some materials may have a lower resistance to wear or may experience higher friction with viscous fluids. The materials should be selected to ensure efficient operation and minimize the risk of pump damage or reduced performance when handling fluids of varying viscosities.
  • Hygienic Requirements: In industries such as food and pharmaceuticals, where strict hygienic standards must be maintained, gear pumps can be constructed using materials that comply with sanitary guidelines. These materials are easy to clean, resistant to contamination, and meet specific regulatory requirements.

3. Application Considerations:

When selecting the size and construction materials for a gear pump, it is important to consider the specific requirements of the application. Factors such as desired flow rates, pressure ranges, fluid properties, temperature conditions, and environmental factors should be taken into account. Proper sizing and material selection ensure that the gear pump can operate efficiently, reliably, and safely in the intended application.

In summary, the size and construction materials of a gear pump significantly impact its performance, durability, and suitability for specific applications. Proper sizing ensures that the pump can meet flow rate and pressure requirements, fit into the available space, and integrate well into the system. The choice of construction materials ensures chemical compatibility, mechanical strength, viscosity handling, and compliance with application-specific requirements. Considering these factors is crucial for selecting the right gear pump for optimal performance and longevity.

Can you explain the design and components of a gear pump?

The design of a gear pump involves several components that work together to facilitate fluid transfer. Here’s an explanation of the design and components:

1. Casing or Housing:

The casing or housing of a gear pump is the outer shell that encloses the internal components. It provides structural support and contains the fluid being pumped.

2. Gears:

The primary components of a gear pump are the gears. Gear pumps typically consist of two or more meshing gears that rotate within the casing. The gears may have cylindrical or helical shapes and are precision-machined to ensure accurate meshing and fluid sealing.

3. Inlet and Outlet Ports:

A gear pump has separate inlet and outlet ports to allow fluid to enter and exit the pump. The inlet port is where the fluid enters the pump, while the outlet port is where the pumped fluid is discharged.

4. Gear Teeth:

The gears of a gear pump have teeth that mesh together as they rotate. The gear teeth create chambers or cavities between the gear teeth and the casing walls. These chambers vary in volume as the gears rotate, facilitating fluid transfer.

5. Sealing Mechanism:

To ensure efficient pumping and prevent fluid leakage, gear pumps incorporate sealing mechanisms. These mechanisms may include clearance gaps, sealing strips, or O-rings between the gears and the casing walls.

6. Drive Shaft:

A gear pump is driven by a drive shaft connected to one of the gears. The rotation of the drive shaft imparts motion to the gears, causing them to rotate within the casing.

7. Bearings:

Bearings are used to support the rotating shaft and reduce friction. They help maintain the alignment and stability of the gears, ensuring smooth and efficient operation.

8. Mounting Base:

A gear pump may include a mounting base or flanges for secure installation and connection to the system or equipment.

9. Optional Components:

Depending on the specific application and requirements, gear pumps may incorporate additional components such as pressure relief valves, filters, gauges, or temperature sensors to enhance performance, control, and safety.

The design of a gear pump focuses on creating a positive displacement mechanism using meshing gears to trap and transfer fluid. The precise engineering and integration of these components ensure reliable and efficient fluid transfer in various industrial applications.
