Device for detecting gears

Abstract

The invention relates to a device for detecting gears. The device comprises a rack, a transmission shaft, standard gears, a gear seat, changeable bushes, a stud and a dial indicator. The device has the following advantages: the structure is simple and reasonable and the manufacturing cost is low; by applying the gear mesh principle, whether the gears have burrs and the specific positions of the burrs can be rapidly and accurately discriminated by observing jump of the pointer of the dial indicator, so the device has high use efficiency, is convenient to operate and is suitable for comprehensively detecting the gears produced in batches; the noises generated by the practical working conditions of the gears can be simulated by adjusting the stud and a compression screw to know the possible problems in advance; and detection of such toothed parts with different moduli as straight teeth, helical teeth and the like can be realized by changing the changeable bushes and the standard gears, so the device has strong universality.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a device for detecting burrs and abnormal noises on gears produced by adopting a shaving and nitriding process. Background technique [0002] In the industrial society of the 21st century, industries such as general machinery and automobiles are prospering day by day, and the gears widely used in these industries have also entered the era of mass production. In the gear manufacturing industry, the shaving and nitriding process is the main method of mass production of gears, which has the advantages of high production efficiency and low cost. However, in the process of producing gears using the shaving and nitriding process, there are the following problems that need to be solved: since the shaving is cut and extruded on the soft tooth surface after hobbing, resulting in plastic deformation, the tooth surface and Tiny burrs are prone to occur on the t...

Problems solved by technology

However, in the process of producing gears using the shaving and nitriding process, there are the following problems that need to be solved: since the shaving is cut and extruded on the soft tooth surface after hobbing, resulting in plastic deformation, the tooth surface and Tooth ends are prone to tiny burrs, and these tiny burrs are only a few wires in size and are not easy to see with the naked eye, but they will generate noise during work, which directly affects the quality of the gear

Since most of the gears and shafts in the automotive industry adopt interference or transitional assembly, assembly line assembly, and the gears are closely arranged inside and outside, if abnormal noise is found during the test run, it is very difficult to find out the burred gear in the gear set and disassemble and replace it. , will take up a lot of time and energy, and seriously affect production efficiency; at the same time, multiple disassembly and assembly will also affect the quality of the whole machine
