Early motorcycle bearing damage causes and analysis

点击数：3949 日期：2014/4/4

Bearing parts of the motorcycle on the use of a lot of activities (such as the direction of column, rear wheel, chain wheel, after the car rear gearbox etc.), precision parts. Bearing the regular factory production in the factory general inspection for qualified products, the use of the correct installation is also very important. In the motorcycle in use process, if the bearing ball retainer off, rolling work surface groove appearance unconventional wear, spalling, due to the rotation of card lag phenomenon, rarely belongs to the bearing itself quality problems, the use of installation of the more. Below, on the motorcycle parts easy problems one by one to analysis, to manufacturers, repair industry and owners attention, to avoid unnecessary losses. The bearing chain wheel on the rear wheel and 1. As the owner in daily use, water too deep or frequent washing, let the water into the bearings, the grease in bearing failure form gradually, bearing rolling groove and ball bearing wear, clearance increases; if the factory or sale of front and rear wheels fitted too tight or too loose, a long time driving caused by instability bearing or bearing, card lag displacement Songkuang, ball cage damage or loss, the formation of the gap is too large, the brake disc and a hub of phase friction, increasing the driving resistance; bearing and chain wheel, easy to water or adjustment of the tight loose, it will make the damage, so owners too deep puddle in the car or should pay special attention to, timely inspection and maintenance. If the damaged replacement must be in place, adjust to the wheels rotate flexibly, without apparent clearance shall prevail. 2 crankshaft connecting rod reducer roller bearings and ball bearings on both sides, two stroke engine is easy to damage. Main reasons causing the connecting rod big head roller bearing damage is: engine oil is too poor or the amount of oil is too small; the engine temperature is too high, increasing friction surface softening, premature working surface fatigue spalling, peeling of particles into the steel column holder, resulting in moving block; roller produced abnormal loads to maintain frame, aggravate the retainer wear, resulting in cage fracture, crankshaft connecting rod locking. Four stroke engine if the replacement of oil shoddy products or use period is too long, lubricating effect of reduced wear intensifies, easy to produce impurities clogging oil road; car assembly or repair, because the field is not enough clean hard foreign bodies or correction for appliances with entering the bearing trench, caused by the hindered rotation of the crankshaft bearing press mounting; not concentric or install crank dislocation, the bearing load increase, causing damage. Bearing on the wheel after 3 charter. General car after the shock is a single support, loading amount is larger, if the bad road condition nor decelerating, abrasion, affect the service life, wash water should pay attention to. 4 steering column upper and lower bearing. Because the front shock failure, insufficient lubrication or upper and lower fastening force discomfort, causing breaking ball or ball surface spalling, formed a steering astringent or deviation, affecting driving safety. In summary: bearing damage mainly to bad lubrication, improper installation is not in place, clearance and environment caused by factors such as bad, if not detected early or repair, it will cause a greater loss or impact on traffic safety. So, please, manufacturers, distributors, repair industry and the owners attention, avoid this type of accident.
