Gear double-sided meshing detection method

Abstract

The invention relates to a gear double-sided meshing detection method. The gear double-sided meshing detection method comprises the following steps: selecting two tested gears to form a tested gear set to perform gear double-sided meshing test, performing data processing on the obtained tested double-sided meshing center distance, and judging the center distance deviation, recording and calculating the actual installation center distance range of the pair of gears according to the backlash, recording the tested gear set in a standard gear test database, and selecting the gear set with the proper actual installation center distance range from the standard gear test database according to the design. The gear double-sided meshing detection method has the advantages that use of a high-precision gear is avoided, and the rate of defective products is reduced.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a method for detecting double-sided meshing of gears. Background technique [0002] The gear double-sided meshing test refers to the measured cylindrical gear and the standard measuring gear or measuring worm, through the elastic compression device on the gear double-sided meshing tester, so that it can be meshed on both sides without gaps and radially By moving or swinging, adjusting the center distance between the measured cylindrical gear and the standard part, using a scale or an indicator to measure the value to evaluate the gear's motion accuracy, working stability and tooth backlash. [0003] But this method has the following problems: 1. It is usually necessary to provide a gear with 2-3 grades or even higher precision than the gear to be tested as a standard gear. During the test, the standard gear will be worn. After a long test, the test The accuracy will decrease, so i...

[0003] But this method has the following problems: 1. It is usually necessary to provide a gear with 2-3 grades or even higher precision than the gear to be tested as a standard gear. During the test, the standard gear will be worn. After a long test, the test The accuracy will decrease, so it is necessary to regularly detect and replace the standard gear. The cost of high-precision gears is high, and batch testing will cause a large number of high-precision gears to be damaged; 2. The test object is a single gear, which is the gear under test meshing with the standard gear, but the actual application The first stage is the meshing of two ordinary gears, and the gear matching work must be carried out according to the actual assembly situation. When the gear test manufacturer and the application manufacturer are not the same, the matching work is difficult to complete
