Question 1

What is the difference between spur and helical gears?

Accepted Answer

Spur gears have straight teeth and are simpler to manufacture, but create more noise and vibration. Helical gears have angled teeth that provide smoother, quieter operation and higher load capacity, but are more complex to manufacture. Choose spur gears for simple applications, helical gears for high-performance requirements.

Question 2

How do I select the correct gear material?

Accepted Answer

Material selection depends on load, speed, environment, and cost. Carbon steel (C45) for general applications, alloy steel (4140) for high strength, stainless steel (316) for corrosion resistance, and brass for non-magnetic applications. We provide material selection guidance based on your specific requirements.

Question 3

What causes gear failure and how to prevent it?

Accepted Answer

Common failure causes: overloading, misalignment, inadequate lubrication, contamination, fatigue, or improper installation. Prevention: proper sizing, alignment, lubrication, contamination control, and correct installation. Regular inspection and maintenance prevent most failures.

Question 4

Can you machine custom tooth profiles?

Accepted Answer

Yes, we machine custom tooth profiles including involute, cycloidal, and special profiles. Provide drawings or specifications including module, pressure angle, tooth count, and special requirements. MOQ typically 100-500 pieces for custom profiles.

Question 5

What is the difference between ground and cut gears?

Accepted Answer

Cut gears are machined using gear cutting machines with good accuracy and surface finish. Ground gears are precision ground after cutting for superior surface finish (Ra 0.4μm) and tighter tolerances (±0.005mm). Ground gears are used for high-precision applications like automotive transmissions.

Question 6

How do I calculate gear ratio and torque?

Accepted Answer

Gear ratio = driven gear teeth / driving gear teeth. Torque multiplication = gear ratio. For example, 20-tooth driving 40-tooth gear gives 2:1 ratio and doubles torque while halving speed. We provide technical support for gear calculations and system design.

Question 7

What heat treatment options are available?

Accepted Answer

We offer various heat treatments: annealing (softening), normalizing (grain refinement), quenching and tempering (high strength), case hardening (surface hardness), and carburizing (wear resistance). Selection depends on material and application requirements.

Question 8

Can you supply complete gear assemblies?

Accepted Answer

Yes, we provide complete gear assemblies including shafts, bearings, housings, and mounting hardware. Send us your requirements or drawings for complete assemblies. This reduces assembly time and ensures proper fit and function.
