Before and during the use of gear wpx175 reducer, the noise of gearbox will be caused by some reasons. This paper describes the causes of box noise in gear wpx175 reducer and the measures to be taken.
Causes of noise after assembly and before use:
① The gearbox itself causes noise due to assembly, gear accuracy and meshing. During the assembly of the gearbox, the installation error of the gear is large due to the poor coordination between the gear and the shaft and the careless operation of the workers, resulting in noise during work.
② Gears are produced in batches and using special machine tools and equipment. Low manufacturing accuracy will also cause gearbox noise.
Causes of noise generated by gearbox during use:
③ During installation, the motor coupling and gearbox coupling are not concentric.
④ The rack platform on which the gearbox is placed resonates with the gearbox to produce noise.
⑤ Without good lubrication, the wear of gears and bearings will become more and more serious with the passage of time, resulting in the increase of meshing clearance between gears, the reduction of meshing accuracy and the generation of large noise.
⑥ After being used for a long time, the bearing breaks due to high load, or the teeth of the gear are knocked off, resulting in noise.
Methods to reduce the noise of reduction gearbox:
① Improve the accuracy of gear and select appropriate gear parameters;
② Train the assembly workers to improve their assembly level and reduce the installation error of gears;
③ Adjust the concentricity of motor coupling and gearbox coupling;
④ Reinforce the rack platform to reduce resonance;
⑤ Improve the lubrication of gears, reduce the wear between gears and bearings and the meshing clearance between gears;
