Common noise problems in WPO175-15 Worm gear reducer are as follows:
Gear related issues
Gear wear: Long-term operation will cause wear, pitting, etc. on the surface of the gear, resulting in the meshing between the gears being no longer smooth, resulting in noise. During severe wear, the tooth shape of the gear will change, further aggravate the noise problem.
Poor gear meshing: If there is error in the gear during installation, or if the gear wears, the meshing clearance may be uneven. In addition, the gear has low accuracy level, and the teeth pitch accumulation error and tooth shape error generated during manufacturing will also cause the gear transmission to be unstable, resulting in pulsation and tooth punching, which will cause noise.
Gear teeth breaking: When the gears are broken, the broken teeth collide with other gears during operation, which will produce a periodic 'click' sound.
Bearing related issues
Bearing damage: When the bearing is worn, the raceway is scarred or the ball is broken, or the cage is damaged, uneven resistance will be generated when rotating, which will lead to noise. If you hear a dull impact sound, it is likely that the bearing balls are loose and the sound of the balls colliding with the raceway during operation.
Poor bearing assembly: Inadequate bearing installation, wear of bearing sleeve or loose bearing lock nuts, etc., will cause abnormal noise during bearing operation. In addition, too large or too small bearing clearance will also affect the normal operation of the reducer and generate noise.
Lubrication system problems
Insufficient lubricant: Lubricant is an important medium to ensure the normal operation of the reducer. Insufficient oil volume will cause direct friction between gears, bearings and other components, thereby causing noise.
Poor lubricant quality: the oil quality decreases, such as black, turbid, floc or reduced viscosity, etc., and the failure to form a good lubricant film between the parts will also increase friction between the parts and generate noise.
Installation and load issues
Unstable installation: If the reducer is installed unstable and the foundation is loose, noise will be generated due to shaking during operation.
Unstable load: The unstable or excessive load the reducer bears, which will cause the internal parts to bear uneven stress, thereby generating noise.
Other questions
There are foreign objects inside: debris or foreign objects enter the machine, which will interfere with the normal operation of the reducer, cause mechanical resonance and generate noise.
Loose parts: In addition to the loose bearing lock nut, other bolts inside the reducer are loose, or the stator core is loose, etc., which can also cause parts to vibrate and generate noise.
Rotor imbalance: Rotor instability or shaft bending causes the rotor to vibrate and cause vibration of the frame, resulting in noise.
