AI Technical Summary

Problems solved by technology

Since the transmission error of the gear is extremely small (0-70μm) and the measured value is extremely sensitive to the measurement conditions, it is difficult for the two encoders to completely realize synchronous sampling, which will affect the accuracy of the results

Embodiment Construction

[0037] A method for measuring gear transmission errors according to the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] First, refer to figure 1 The gear transmission system used in the gear transmission error measuring method according to the present invention will be described. The gear transmission system includes an angular velocity encoder 1, a driving device 2 (for example, an engine) and a pair of meshing gears. The pair of meshing gears includes a driving wheel 3 and a driven wheel 4 . The angular velocity encoder 1 and the driving device 2 are installed on the input shaft 5 of the driving wheel 3 to measure the angular velocity of the driving wheel 3 The driven wheel 4 is connected to an output shaft 6 . The power of the driving device 2 drives the driving wheel 3 to rotate through the input shaft 5, thereby driving the driven wheels 4 which mesh with each other to rotate.

Abstract

The invention discloses a method for measuring gear transmission error. The method comprises the following steps of: firstly, measuring angular velocity of a driving gear through an angular velocity encoder, and then obtaining angular displacement; secondly, substituting the angular displacement into a kinetic equation, and obtaining the gear transmission error through corresponding calculation. According to the method for measuring the gear transmission error, the transmission error with higher accuracy can be obtained, and compared with a traditional method, one angular velocity encoder is omitted, the influences brought by desynchrony of two angular velocity encoders are overcome, and simplicity and convenience are realized.

Description

technical field [0001] The present invention relates to a method for measuring transmission error of gears, more particularly, relates to a method for measuring transmission error using only one angular velocity encoder. Background technique [0002] As an important transmission part of the modern automobile industry, the gear is one of the main sources of vibration and noise during the operation of the automobile. Its dynamic behavior and working performance have an important impact on the entire vehicle. Car manufacturers also attach great importance to reducing the vibration and noise of gears, and regard it as a highlight of new cars. Vibration, noise and comfort are one of the concerns of major vehicle manufacturers and parts companies in the international automotive industry. The vibration of the gear not only affects the failure mode of the internal gear, such as: gear fracture, tooth surface pitting and peeling, tooth surface gluing and tooth root crack, etc., but a...
