Our company can produce about 10 kinds of precision gears, including common spur gears, helical gears, worm gears, bevel gears, etc., but the most popular types of precision gears we can produce are the following four.

The most commonly used precision gear is the spur gear, distinguished by its simple tooth shapes and parallel gear shafts. Typically employed to convey rotational motion and torque, its relatively simple design and manufacturing techniques, combined with great efficiency, contribute to the spur gear's excellent performance in terms of low noise and high accuracy. This is due to the tooth surface running straight and parallel to the gear axis.

High transmission efficiency

Straight tooth surface of spur gears allows them to produce effective power transfer, therefore reducing energy loss to the best of degree.

Simplified manufacturing technique

Spur gear manufacture is easier than that of other kinds of gears, therefore lowering manufacturing costs.

Low noise and vibration

The spur gear generates quite little noise and vibration when running.

Mostly employed in various industrial sectors, particularly in the automotive sector, helical gears are the most often occurring forms of bevel gears and hypoid gears. Among the fundamental parts of mechanical transmission systems are helical gears. Their tooth surface structure is complex, and the structure and machining adjustment of gear cutting machines are the most complicated. Simultaneously, cutting tool settings, machine parameters, loading deformation, and assembly mistakes may all affect their meshing, load-bearing, and vibration performance, thus making quality control of helical gears rather challenging in design and production.

Smooth Transmission

Gradual engagement of helical gears results in superior smoothness than spur gears, hence lowering shock and vibration.

High Transmission Efficiency

Helical gears' increased contact surface causes transmission efficiency usually to be more than 90%.

Lower Noise and Vibration

Because of constant meshing, helical gear transmission generates less noise and vibration than spur gears.

Higher Load Capacity

Increased tooth contact area lets more axial and radial load-bearing capability possible.

Good Self-locking Capability

Helical gears are good for uses requiring protection against inadvertent movement or reversal as they stop reverse rotation.

		Type of gear	Helical gears
		Diameter Range	3-300mm
		Precision	ISO 6-7 precision hobbing

Commonly utilized in transmission systems between two shafts either perpendicular or almost perpendicular to one another, bevel gears are a kind of conical gear with a tooth shape like a cone. Often used in applications like automobile differentials, equipment, and power tools, bevel gears serve primarily as means of changing the direction of power transmission.

Direction Change

Particularly for 90-degree transmissions, bevel gears are perfect for uses requiring axis of rotation modifications as they can transfer power at different angles.

High Transmission Efficiency

Bevel gears' tooth surfaces may make tight contact during operation, thereby reducing energy loss and so enhancing transmission efficiency.

Variety of Tooth Profiles

Based on need, bevel gears may be straight, helical, or curved tooth shapes; helical bevel gears and curved bevel gears provide higher smoothness and load-carrying capability.

High Load Capacity

Bevel gears are extensively utilized in heavy equipment and automobiles as their design helps them to resist large torque.

Higher Manufacturing Costs

Bevel gear manufacture is sophisticated and calls for strict production standards and great accuracy, which drives somewhat higher prices.

		Type of gear	Bevel gears
		Diameter Range	3-300mm
		Precision	ISO 6-7 precision hobbing
		Materials	High-strength steel, titanium alloy, aluminum alloy, plastic
		Processes	Advanced gear forming and heat treatment processes ensure high precision and durability.

One kind of conical gear with helical tooth profiles is helical bevel gear. Compared to conventional spur bevel gears, its curved spiral tooth surfaces provide smoother engagement, reduced noise levels, and more load-carrying capability. Applications such automobile differentials, machine tools, and aerospace equipment that need for great accuracy and load capacity often find helical bevel gears in use.

Smooth Engagement

Helical bevel gears engage gradually, therefore lowering shock and vibration for a smoother transmission, based on their helical tooth design.

High Load Capacity

The helical shape enhances the contact surface, thus enabling them to handle greater loads and so fit for high-torque and high-power transmission uses.

Lower Noise and Vibration

Comparatively to spur bevel gears, the progressive engagement of helical bevel gears reduces collisions between the gears, hence producing lower noise and vibration.

Suitable for High-Speed Transmission

Ideal for uses needing high-speed transmission, helical bevel gears preserve smooth operation and great efficiency at high speeds.

Axial Force Generation

Axial Force Generation: Axial thrust produced by the helical tooth design has to be taken into account in the design to guarantee appropriate bearing configurations to balance this force.

Complex Manufacturing Process

The machining of helical bevel gear tooth profiles is more difficult than that of spur bevel gears, which increases production costs; nonetheless, their better performance results in more applications.

		Type of gear	Spiral bevel gears
		Diameter Range	3-300mm
		Precision	ISO 6-7 precision hobbing
		Materials	Steel, aluminum alloys, titanium alloys, tungsten carbide, plastics and composites
		Processes	Advanced gear forming and heat treatment processes ensure high precision and durability.
