Matters needing attention in gear applications

The matters needing attention in gear applications, such as whether there is no backlash, whether solid lubricating oil can be used, whether the shaft can be fixed with a jack screw, etc., may not be very clear to many people. The following EP will answer them one by one for your reference.

1. Can gears have no backlash?

Backlash is the distance between the tooth surfaces when a pair of gears are engaged.If the backlash is too small, it will not rotate smoothly, accelerate product wear, make loud noises, and greatly reduce service life. Therefore, proper backlash can make the product rotate smoothly.

2. Can solid lubricants be used?

Gear lubrication is generally an oil bath type, but solid lubricating oil is often used in an environment where the speed is lightly loaded or when used in an open mode with rack and pinion gears.

It is necessary to use suitable solid lubricants and frequent maintenance.

Turbine and umbrella teeth tend to generate heat during bite movement, so choose solid lubricating oil with good cooling effect.

3. Is it possible to use jack screws to fix the shaft, and how much torque can be transmitted when the jack is used to fix the shaft?

It is better to use the key and bushing (friction connection parts) together when it is actually used, because the jack screw fixing shaft is a simple fixing method.

4. What is the difference between gear tooth surface strength and tooth bending strength?

Gear tooth surface strength and tooth bending strength are the two major strengths of the product. The former is the maximum contact stress that the product can withstand during occlusion; the latter is the maximum bending stress that the product can withstand during occlusion. They are different. .
