4 precision requirements for precision cylindrical gears

The four precision requirements of precision cylindrical gears are as follows, for reference.

1. Work stability

gearThe transmission movement is stable, and the impact, vibration and noise should be small.

2. Motion accuracy

The gear can accurately transmit motion, and the transmission ratio is constant.

3. Tooth side clearance

During gear transmission, a certain gap is left between the non-working tooth surfaces to store lubricating oil and compensate for dimensional changes caused by temperature and elastic deformation and some errors in processing and assembly.

4. Contact accuracy

When the gear is working, the contact of the tooth surface should be even, and a certain contact area and a contact position that meets the requirements should be ensured.

The manufacturing precision of the gear itself has a great influence on the working performance, carrying capacity and service life of the entire machine.OneCylindrical gearThere can be one or more ring gears.

a. Ordinary single ring gear has good manufacturability;

b. The small ring gear of double or triple gears is often affected by the shoulder, which limits the use of certain processing methods. Generally, only gear shaping can be used.

c. If the gears require high precision and need to shave or grind gears, the multi-ring gears are usually made into a combined structure of single-ring gears.

The above is the description of the accuracy requirements of cylindrical gears shared today. If there are any deficiencies, please add them.
