Abstract

The invention discloses a method and a device for detecting wear of a tooth surface of a large involute spur gear. The method and the device are used for efficiently detecting the degree of wear of the large gear. The method includes fixing the detected gear; placing a three-jaw chuck in a shaft hole of the detected gear; respectively reading indicated values of the position of a positioning slider on a primary positioning scale and a secondary positioning scale from the first positioning scale and the secondary positioning scale and denoting the sum of two read numbers as Y; directly reading the expansion distance of a measuring jaw on the measuring jaw and denoting a value of the expansion distance of the measuring jaw as X; measuring the distance from the tip of the measuring jaw to the center line of the detected gear, simultaneously reading a value of the distance on a measuring scale and a vernier scale and denoting the value as Z which is a measured wear extent of the detected gear. The measuring device comprises the three-jaw chuck, the primary positioning scale, the secondary positioning scale, the positioning slider, the measuring scale, the vernier scale and the measuring jaw. The method and the device have the advantages that the method and the device are applied to detecting large gears, and the difficult problem that large gears cannot be detected by large quantities of precision gear detectors is solved.

Description

technical field [0001] The invention relates to a method and a device for detecting the wear of mechanical parts, in particular to a method and a device for detecting the wear of a tooth surface of a large involute spur gear. Background technique [0002] Gear mechanisms are commonly used to transmit force between two shafts. Because of its large transmission power, high transmission efficiency, and a series of advantages such as long service life, it is widely used. But gear wear is a serious problem that has been plaguing the machinery industry. Therefore, detecting the degree of gear wear is particularly important for the repair of the gear and the normal operation of the machine. [0003] At present, the gear testing equipment that is widely used includes: CNC gear testing, gear double-sided meshing instrument, gear online measurement and sorting machine, laser gear measuring instrument and ultra-precision three-coordinate measuring machine, etc. The cost of these dev...
