First, the appearance of the sound. The transmission rang after the gear was hung up; it is because the gears that mesh with each
Other have the consensus effect of the impact and the cavity of the transmission housing during operation.
Second, the cause of the sound. 1) The transmission system (clutch, drive shaft) outside the transmission is in poor technical condition; then in use; attack and oscillation; causing the transmission to resonate; exhibiting resonant noise. This noise is often none. Regular; will occasionally occur in a certain speed range.
.2) The transmission device is not properly; the gear or needle bearing and bushing of a certain gear position of the transmission are not properly replaced; the gap of the device is not normal; the gear is not properly meshed and the noise is abnormal when the gear is formed.
.3) noise caused by other elements in the transmission; noise caused by many factors such as the logarithm of the working gear, the rotational speed, the operating standard, the load, and the too low lubricating oil; some noise can be removed by not crashing when viewed Some can not be removed; only crash repair; and only after each part is satisfied with the skill requirements; only complete cleaning; especially when replacing gears should be replaced in pairs; ensure that the gears have excellent meshing. Pay close attention to the gaps in each part; make it comply with the regulations.
.4) Because a single gear face is broken; forming a collision during the meshing process. When the gear is engaged; a severe impact and oscillation will occur; then the consensus of the transmission housing is caused.
.5) The transmission housing is damaged; the transmission housing and the housing bore are worn and deformed for a long time. This sound is loudest when it is hung in the low speed; followed by the high speed; the sound is gradually decreased; the direct gear is minimum.
