Work stainless bearing, bearing clearance refers to what reason be

So, what causes the reducer bearing chamber wear failure? Sauvy our industrial engineer analysis has the following reasons: daily maintenance does not reach the designated position, leading to the casing of the lubricating oil system of impurities deposition is more, equipment in the process of running denier these impurities into horizontal installation of the high-speed shaft bearing raceway bearing accident jammed; Equipment operating characteristics, frequent start or point moving astern, and causes of the high speed shaft vibration serious; Reducer casing material problem, because of the speed reducer box body is composed of integral casting processing, local material without heat treatment and surface treatment etc, in the process of the equipment in the long run due to the fit precision problem between the components, the gear meshing vibration problem, start, stop the impact of vibration causes such as the wear of the bearing chamber. Bearings and shaft is too loose, The smaller the diameter of the shaft or set set not tighten) ； Rotates, the bearing clearance is too small, too tight, Set set of tighten too far) ； 。 一个mm - , according to our current experience through the current will not result in bearing damage, however, when the current density is equal to or greater than Amm - , bearing internal will appear obvious electric erosion. & emsp; & emsp; Analysis: the bearing life is longer than the bearing, bearing cataclastic driven pumps cannot work; The bearing and the bearing cavity filled with coal cinder is, sand and water bearing under rapid failure of the direct and main reason; Bearing and bearing cavity filled with coal cinder, sand and water is derived from the motor chamber, such as motor cavity working condition of coal cinder, sand, etc from water, the reason is the skeleton oil seal & amp; emsp; & emsp; Such as the wear failure. Below is master maintenance for owners to replace the whole process of release bearing, in desperation, the owner agreed to master apart the engine and the gearbox, release bearing inspection! Replacement car clutch sets of work is relatively complicated, the teacher need to separate the transmission and engine, it takes a lot of time and effort! Due to the lower down the shaft, the transmission will leak, so the teacher need to give out the transmission oil. In addition, lubricating oil ( Or grease) Itself in the operation of the poor quality of a material or gas ( Fat) Not in time, is also a common phenomenon, such as belt conveyor roller bearing into the rain, rotary feeder pulverized coal bearing and the bearing fuller pump into or raw powder, can cause bearing temperature rise and produce different sound. & micro; m - , and raw material sintering process in order to achieve the required temperature required a lot of energy on high energy and processing cost. Repair field enterprise personnel and sauvy collaborate with technical staff, staff by the enterprise is responsible for disassembling bearing and shaft surface processing, including surface oil removal and surface grinding, sauvy technical staff responsible for on-site equipment repair process recovery bearing the size of the work, the field is more smooth, 2-seeded hour bearing a repair work is complete. （ B） Level - — Used in high speed, rotating accuracy requirement is high, such as gear grinding machine, precision coordinate boring machine spindle bearing, the main bearing high precision instruments and meters, etc. And ABEC this standard is not practical for skateboarding, because most slippery hands sliding less than miles per hour, unless you went to the mountain, so ABEC basic doesn't make any difference. Take the bearing of each measurement point of the crest factor of great value as the bearing acceleration wave factor, summary, bearing is highly sophisticated and core components, be sure to use according to the parameters. This kind of adhesive - — Tear - — Adhesion of cycle constitutes the adhesive wear and, as a mild adhesive wear is called a scratch, serious adhesive wear called occlusion.
