Evel gear hard tooth surface reducer idling has abnormal sound

Evel gear hard tooth surface reducer idling has abnormal sound, abnormal sound similar to gear engagement is not good, tooth situation of abnormal ring!No ring after load!This happens very often!No high point of the gear was found after the inspection.
From the cause of abnormal sound, the abnormal sound of planetary reducer can be divided into two categories: one is abnormal bearing coordination, abnormal gear engagement; the other is the loose connection between parts, parts damage, this abnormal sound is mostly abnormal friction and collision between parts, so the sound is relatively clear.
Unnormal gear engagement refers to too small or large engagement gap, incorrect engagement part, insufficient engagement area, continuous clear sound and sound with increasing speed; abnormal bearing clearance is too large or too small, continuous noise and increase with increasing speed.
1, active cone gear protrusion edge fastening nut loose.Its performance is:
Whnoise sounds during load operation and disappears at constant speed.
2, cone from the gear beating or faulty.
In a word, in addition to the high speed will produce a certain noise, whenever there is an abnormal noise to attract attention in time, timely inspection.Avoid damage to the entire speed reducer due to minor problems.
