As for the cause of reducer bearing hair ring, do you know how many? - bearing knowledge

Reducer is a kind of the closed in rigid casing of gear transmission, worm drive and gear - Worm drive composed of independent components, commonly used as the machine moving parts and work between the reduction gear. Between the prime mover and work machine or actuator has a function in matching speed and transfer torque is widely used in modern machinery. But in the process of we use reduction opportunities, the phenomenon of the reducer bearing hair ring, small make up then share some bearing ring reasons for everyone, convenient you better find out the cause and the solution! 1, the speed reducer of oil containing impurities. 2, reducer lubrication. Save, for example, the oil level is too low for lead to oil or grease seal leakage. 3, bearing in the mixed with sand or impurities such as carbon, abrasive effect; Bearing in the mixed with water, acids or paint such as dirt, corrosion effect. 4, the axial thermal elongation is too large, axial additional load bearing is statically indeterminate. 5, additional load reducer bearing and bearing axial awful a tight, may also be a shaft with two fixed end bearing. 6, with the bearing and the shaft is too loose. The smaller the diameter of the shaft or sleeve not tighten. 7, and the bottom surface of the bearing pad iron, lead to a hole deformation and crack of bearing seat. 8, bearing hole with sundry. 9, left the position of the oil ring is not appropriate. There, ball or roller pressure in the pit. 11, bearing noise and vibration source outside interference. 12, bearing heat discoloration and deformation. 13, bearing noise. 14, bearing hole bigger, non-ferrous metal bearing hole was enlarged, or due to thermal expansion. 15, shoulder holes of the block is too large, send the bearing seal touch to distort. 16, labyrinth seal gap is too small and shaft friction. 17, lock washer of tooth bending bearings and friction. 18,. Shaft is too coarse to make actual fit too tight ( Cause the bearing temperature too high or noise. 19, small diameter of hole, resulting in high bearing temperature. 20, bearing hole diameter is too large, the actual fit is too loose. You also know what the cause of the reducer bearing hair ring, hurriedly to share together!
