Problems solved by technology

[0005] ①The design is based on the subjective experience of the engineer, and there is a lack of quantitative indicators to guide the gear modification design, so it is difficult to ensure the effectiveness of the modification design
[0006] ②Using the contact spot test to verify the microscopic modification, it is difficult to put forward quantitative optimization suggestions for the microscopic modification. Usually, it is necessary to carry out multiple cycles of design→test→optimization to achieve a good modification result, and the cycle is long

Embodiment Construction

[0038] refer to figure 1 , which shows the structural principle of the bench for wear test used in the embodiment of the present invention. Take the wear test of the automobile gearbox as an example. After the gearbox to be tested is installed on the bench, the output shaft of the driving motor is mechanically connected to the torque and speed sensor, and the output shaft of the torque and speed sensor is mechanically connected to the driving disc of the safety clutch. The driven disc of the clutch is mechanically connected to the input shaft of the gearbox to be tested, the output shaft of the gearbox to be tested is mechanically connected to the input shaft of the reducer, and the output shaft of the reducer is mechanically connected to the output shaft of the loading motor. The control system is electrically connected with the driving motor, torque, speed sensor and loading motor to control the whole test process. In this way, the torque output by the drive motor is transm...

Abstract

The invention provides an abrasion-test-based micro profile modification design method for a gear. The method comprises the following steps of (1) drawing a gear tooth profile detection curve and a gear tooth direction detection curve before an abrasion test; (2) performing the abrasion test; (3) drawing a gear tooth profile detection curve and a gear tooth direction detection curve after the abrasion test; (4) determining a tooth profile modification mode and a tooth direction profile modification mode; (5) determining a tooth profile modification position; (6) determining a tooth profile modification amount and a tooth direction modification amount. The invention also provides an abrasion test bed. According to the method and the bed, the micro profile modification design efficiency and accuracy of the gear can be improved.

Description

technical field [0001] The invention relates to a gear manufacturing method and testing equipment, in particular to a gear microscopic modification design method and a stand for wear testing of gears. Background technique [0002] With the development of involute gear transmission technology and the gradual improvement of gear processing technology, higher requirements are put forward for the load-carrying capacity, transmission quality, vibration and noise of gears in gearboxes (such as automobile gearboxes). [0003] During the actual load transmission process of involute gears, due to the elastic deformation of the gear teeth after being stressed, the pitch changes, and the shafts, bearings, and housings (boxes) supporting the gears will also undergo elastic deformation, resulting in The meshing misalignment of the gears changes the transmission characteristics of the gears, resulting in uneven distribution of tooth surface loads along the tooth width and tooth height dir...
