Problems solved by technology

In addition, the research on gear wear at this stage is mostly about its design, application and repair, and seldom involves the wear analysis of the manufacturing process. However, the wear behavior in the production process, such as tooth profile machining error, also affects the properties and service life of the gear working surface. one of the key factors

Abstract

A comprehensive abrasion service life experiment table for an involute gear is characterized by comprising a bottom plate (13), a drive gear shaft (5), a driven gear shaft (2), a pair of drive gear bearing blocks (6), a pair of driven gear bearing blocks (1), a drive gear (8), a driven shaft coupler (18), a driven gear (22), a drive shaft coupler (11), a drive motor (12) and a load brake (15). The drive motor (12) is connected with the drive gear shaft (5) through the drive shaft coupler (11) to drive a pair of the drive gear (8) and the driven shaft coupler (18) to perform meshed movement. The load brake (15) connected with the driven gear shaft (2) through the driven shaft coupler (18) adjusts system loads. The experiment table is compact in structure, convenient to assemble and capable of achieving mounting error, load and rotation speed adjustment and performing abrasion service life experiment on gears of different machining accuracies.

Description

technical field [0001] The invention relates to a medium and small gear wear test bench. In particular, it is a comprehensive test bench for wear life of involute gears. Background technique [0002] At present, the widely used involute gears are currently developing in the direction of high load, high speed, high efficiency and low noise. Improving bearing capacity, prolonging service life and reducing noise have become the key technologies to improve the quality of gears. Due to the influence of machining accuracy and tooth shape modification, the profile of involute helical teeth is usually not an ideal involute; after a long period of work, the tooth surface of the gear tooth will also slowly wear out, and the profile will further change , As a result, the contact conditions of the gears also change, the transmission speed is no longer stable, the vibration is strengthened, the noise is increased, the transmission is not smooth, and a series of problems, and even have ...
