1. Improve the gear processing accuracy of the gear reducer
The shaft tooth accuracy of the gear reducer is mainly related to the motion accuracy, stability accuracy and contact accuracy. In the hobbing process of gear reducer, the common normal line length and the gear ring diameter jump are controlled to ensure the movement accuracy, the tooth profile error and the base pitch deviation are controlled to ensure the stability and accuracy of the work, and the tooth direction error is controlled to ensure the contact accuracy.
At present, the gear processing method of the gear reducer is gear hobbing and gear shaving. The requirements are relatively strict. Only by using this technology can produce high-precision gears, and the gear shaving accuracy can calibrate the gear reducer to a large extent. Therefore, some error items in gear hobbing must be strictly controlled in order to manufacture high-quality gears.
2. Reduce the radial runout error of the ring gear of the gear reducer
The radial runout of the gear ring of the gear reducer refers to the amount of change of the probe relative to the axis of the gear tooth within the range of one revolution of the gear, the probe is in the tooth groove or on the tooth, and the tooth height is in double-sided contact. That is, the eccentricity of the gear ring gear of the gear reducer with respect to the center line of the shaft. This eccentricity is due to the fact that the two center holes of the parts and the rotation center of the worktable do not coincide or the deviation is too large when the parts of the gear reducer are installed. And cause. Therefore, reducing the ring gear radial runout error of the gear reducer can effectively improve the quality and accuracy of the gear.
If the gear quality and accuracy of the gear reducer are not enough, it will not only accelerate its own wear, but also greatly reduce the service life, and it is not conducive to the stable operation of the gear reducer. Then analyze and solve the gear quality of the gear reducer from the above two points. The problem of precision and precision is beneficial to strengthen the deceleration effect and transmission force of the gear reducer, and can effectively reduce the occurrence of failures.
