Abnormal noise of gearbox

1. The noise caused by bumps and stumbling on the gear box tooth surface: this problem is mainly reflected in the test bench of the general assembly plant of all the machine and equipment manufacturers of the gearbox. The characteristics of such abnormal noises are: the sound frequency is stable, the one side has sound, and whether the reverse rotation has noise. The specific address caused by the noise can be determined by calculating the transmission ratio of the low speed gear shaft and the frequency relationship of the noise. Cause: there are bumps and trips during the whole process of installation. Because of the negligence of the enterprise in the experiment quality, there are a small number of gearbox which may be difficult. Treatment: carefully find the contact place on the tooth surface of the relevant transmission gear according to the analysis results. When looking for, clean and clean the oil on the tooth surface to prevent the hand feeling from being hurt. The impact injury is important in the angle of engagement and both sides of the tooth profile.

2. Noise caused by too large error of gear box: the problem is also reflected in the general assembly plant of all machine and equipment manufacturers. The characteristics of such noise are: the sound frequency of Rx gear reducer is stable, and the sound is both rotating in two directions. Cause: noise of adjacent gearbox caused by production and processing of shaft sleeve

3. Noise of friction interference: the problem is very likely to appear in the machine repair workshop. It is hard to open the brake or the brake is not moving. During the trial operation, the gear reducer supplier will send the friction sound. The reason of wind field is that the air rejection ring and the end cover of rolling bearing interfere, and the abnormal heating phenomenon is found in the relevant parts. Treatment: look for pre-made components that interfere with friction, repair and manufacture parts or tighten them. The gearbox water temperature is too high 1. The common problems of the air cooler such as short circuit of wire, short circuit fault, motor damage, etc. cause the fan to not operate.

4. Dust damage the heat pipe radiator of the air cooler, many dust cover the S series helical gear worm gear worm gear reduction opportunity, damage the exhaust heat of the air cooler, resulting in insufficient cooling of lubricating grease.

5. The wrong routing of the air cooler leads to fan rotation, which will cause the opposite wind frequency and damage the heat discharge. Above is the gearbox difficult problems and other solutions, friends can be based on the above problems and solutions can be more powerful application gearbox.
