Problems solved by technology

[0003] At present, the most extensive gear processing technology is limited by the precision of the mold. The degree of meshing between gears of different specifications cannot meet the high standards in the industry. Most gear transmission structures such as offset gears rely on imports.

Embodiment Construction

[0032] A grinding method of an offset gear, the offset gear includes a main gear 11 and an auxiliary gear 12, the steps are as follows:

[0033] S1. Apply abrasive paste between the tooth surfaces of the main gear 11 and the auxiliary gear 12. The particle size of the abrasive paste is 800-900 mesh, and mesh and fix the main gear 11 and the auxiliary gear 12.

[0034] S2. The pinion gear 12 rotates on its own and maintains a relatively fixed position in the space where it is located. The pinion gear 12 drives the main gear 11 to rotate.

[0035] S3. Apply a force of a set size to the contact surface between the main gear 11 and the pinion gear 12, the force of the set size is parallel to the axis of rotation of the main gear 11 and applied to the shaft of the main gear 11; and the The form of force application is: when starting grinding, the force starts from 0 N, after 10-15 times of force application, it reaches 200 N at the end of grinding; adjust the speed of pinion 12 to ...

Abstract

The invention relates to a method for grinding an offset gear, the offset gear comprises a main gear and an auxiliary gear, the method comprises the following steps: S1, coating grinding paste between the tooth surfaces of the main gear and the auxiliary gear, and meshing and fixing the main gear and the auxiliary gear; s2, the auxiliary gear rotates, the position of the auxiliary gear in the space is kept relatively fixed, and the auxiliary gear drives the main gear to rotate; s3, applying force with set magnitude to the contact surface of the main gear and the auxiliary gear, adjusting the rotating speed of the auxiliary gear to be 20-60 r / min, and grinding for 20-30 min; S4, detecting the contact degree between the main gear and the auxiliary gear by using red lead, and judging that grinding is completed when the contact degree reaches 80% or above. The method is simple and easy to operate, the matching degree of the gear is adjusted through grinding, the problem that the precision of the gear is not high in the production process can be solved, a common gear can also reach the high-precision standard, the manufacturing cost is greatly reduced, and various application requirements are met.

Description

technical field [0001] The invention relates to the technical field of gear processing, in particular to a grinding method for offset gears. Background technique [0002] Gear transmission is the most typical meshing transmission, and it is also the most widely used transmission form. Gear rotation requires that the modulus and tooth angle of the contacting gears be equal, so there is a high requirement for the machining accuracy of the gears. In gear transmission, the meshing deviation will not only cause vibration, noise and wear and tear when the gear is working, but also lead to problems such as broken teeth and bearing damage due to uneven force, which will eventually lead to mechanical failure and cause safety hazards. In some precision instruments, gears with general meshing precision cannot be used at all. [0003] At present, the most extensive gear processing technology is limited by the precision of the mold. The degree of meshing between gears of different spec...
