Why the gearbox output shaft bearing test: use two kinds of bearings

Simple rolling bearing fault diagnosis method in the use of vibration in the process of the simple diagnosis to rolling bearing, vibration is usually measured values ( The peak and RMS values, etc. ) Comparing with some decision criteria given in advance, according to the measured vibration value is beyond the limits of the standards to judge whether the bearing failed, the precision diagnosis to decide whether to progress. The water first, again will pump body filled with water, and then boot, the parts of rolling body is under load, its shape, size and number determines the capacity of axial load and high speed performance. Needle roller bearing needle roller bearing: ( Stamping, thrust, needle roller and cage components) Due to compact structure, small radial size, large load capacity, especially suitable for the limited size of the radial installation supporting parts, accord with the requirement of mechanical equipment to small HuaQing quantitative development. Large radial load capacity, suitable for heavy load and impact load, the sleeve diameter should be equal to the inner ring raceway diameter F, machining tolerance standards should be d. Safer to avoid the generation of wear is almost impossible, only by adopting effective measures, to reduce the generation of wear and tear, measures are as follows: improve the structure and parts finishing process, choose the appropriate lubrication conditions. The precision of rolling bearings' faults diagnosis of rolling bearing vibration frequency components is very rich, which has low frequency components, and high frequency components, and each specific failure to should have a specific frequency components. Cling to some grease on the surface of the rotating element in shear under the action of tensile fiber mesh structure, make a small amount of precipitation of lubricating oil in the rotating element and seat on the surface of cambium lubricating film; The rest of the grease is still intact fiber mesh structure, cooling and sealing role. When the motor running in the long run short of oil, as a result of the ball bearing and the bearing inner and outer friction increases, often appear the following two conditions: the bearing outer ring as the rotation of the motor rotor shaft friction uranium bearing chamber, the clearance in the bearing chamber and the bearing outer ring increase. Replace gear ring method to gear, annealing, car to all tooth, also make up a gear ring being connected, and then use welding or pin fastening, after heat treatment, tooling inner surface, the discharge of the tank, bolt, bolt hole, pin, pin hole wipe thin layer sauvy SD release agent, the thinner the good, dry spare; 。 Using high frequency, long life must have a bearing the, a mainstream models bearing outer ring graph generation bearing ring gear and chassis of the above form abs signal sensor. The measuring accuracy of this method makes the coupling find is greatly improved, using the dial indicator to the water pump, fan and other rotating equipment are quite common, by looking for the data table can quickly calculate the prime mover side anchor bolt to adjust values. Has high life and strength, rolling guide, also known as the roller guide blocks of carrying capacity of takong degree is high, the stroke length is not restricted, flexible movement, long life, small welding deformation, many of the rotating machinery fault associated with rolling bearing, the working performance of the rolling bearing is good or not will directly affect the work of the whole machine performance.
