The difference between bearing and air conditioning: bearing zv2 and ZV3 big

Some wheel core is very tight, bearing is hard to tear open come down to, with the hexagon wrench ( Is the same) that screw down the It hard to dig down, rest assured, bearing it is not easy to bad. Metal material concession sex difference, the longer it is easy to cause micro fit clearance, if not found in time and take measures, will cause the micro gap widening, directly run bearing inner ring, bearing damage. In this state for forging, the material by a heavy hammer forging, torn parts, form a larger holes, most of such defects appear on the chamfer, end face and inner diameter. Raceway surface of the metal strip surface stripping operation reasons: excessive torque load, lubrication, the speed change frequently, vibration, bearing in the condition of inclined installation, card. Roller bearing is used to carry heavy load, the ball bearing used in light or medium under load, carburizing steel bearing manufacturing or bainite hardening, can withstand the shock and vibration load. Countermeasures; By adjustment to adjust the right registration, to ensure that the axis of the coupling in the straight line, especially when the shaft and bearing one or more work, more attention. Then a good bearing and bearing assembly on the shaft, pushed to the required location for installation, fixed bolts do not tighten the bearing seat, to make bearing coat in bearing internal energy. （ Chart that is good, it is recommended that you collect, for a rainy day! ） Found in the inspection process of converter drive side bearing a badly worn with bearing on both sides of the seal failure, thus resulting in bearing abnormal sound equipment in operation process, the rotation is beating equipment safety hidden trouble. Many friends said this is an extended version of BMW or open BMW before? After seems to become a driving a Mercedes and sat mercedes-benz, are looking forward to, but there are some think before is because after its size is small, the city is better parking inside, but now is lengthened. For wide speed range of gas bearing friction is low, low temperature, the speed is as high as thousands of RPM, the temperature rise shall not exceed the ~ ℃, speed is even up to thousands of revolutions per minute. & emsp; & emsp; Generator after the front bearing end cover, bearing end cover, bearings front to build a relatively closed space, produce gas, only from the generator before bearing gap between front cover and the generator shaft, caused by friction, coupling skid generator shaft front and coupling torque limiter in temperature is very high, so that the combustible gas ignited, and between the coupling and coupling cover combustion, the heat generated by the continued the generator shaft front and bearing end cover before heating, front end cover and the generator shaft front of high temperature gasification and progress within the bearing grease. When bearing at high speed, rolling element and cage with high rotate speed makes the surrounding air, the air with a lubrication methods are difficult to be sent to the bearing lubricating oil, use the method of high-pressure jet spray the lubricating oil must be taken to the bearing, the position of the nozzle must be between inner ring and maintains a center.
