Disintegration of inspection reducer: 1 gear overhaul: ⑴ damage in the form of gear: A, broken teeth: This is mainly due to improper operation caused by the impact, resulting in a heavy load caused by the material hardening and fatigue caused by tiny cracks and is gradually expanding The reason of broken teeth. B, bad tooth contact: both gears meshing process, not the tooth surface along the tooth length and tooth height direction achieve the required good contact. This phenomenon will cause accelerated wear of tooth surfaces or partial destruction caused by the accident. Causes are two gears meshing center distance or two parallel shaft gear tolerance maintenance technology agreements and large gear manufacturing error. C, tooth wear: one refers to the long-term normal wear and tear over a certain limit, the other refers to the damage caused by abnormal wear and tear, including adhesive wear gear maintenance, abrasive wear and corrosion and wear. Causes tooth hardness is undesirable, the load is too large and lubricants undesirable. D, tooth surface pitting: both tooth surface pitting fatigue, tooth surface roughness, caused by lubricating unclear. E, plastically deformed teeth: tooth surface quenching hardness uneven (or quenching) is part of the software permanently deform the surface reducer repair steps, the formation of the tooth surface caused by uneven or crooked teeth. Adjustment of the rolling bearing: rolling bearing between the inner and outer rings rolling elements and a gap, the gap is too large prone to vibration and noise, but the gap is too small and easy to cause severe heat and wear. Both will make the bearing life is shortened. Rolling into the adjustable gap is not adjustable in two. Non-adjustable bearing clearance (eg, radial ball bearings), it has been given clearance to ensure that at the time of manufacture. But because of different conditions, thermal expansion of the shaft, axial movement reducer repair method, the bearing clearance is reduced, and even rolling body stuck. Therefore, these bearings during assembly, a fixed bearing, the other end of the shaft between the bearing and the end cap leaving an axial gap, and its value is generally between 0.25 to 0.5 mm (excluding high-temperature environment).
