Abstract
The utility model relates to an insulation structure of a bearing assembly. The insulation structure comprises an inner bearing cover, a bearing, a first insulating plate, an inner shaft sleeve, an insulating bonding layer, an end cover, a bearing sleeve, an insulating casing pipe, a second insulating plate, an oil retainer, an oil flinger, an outer bearing cover and a shaft. The bearing is installed on the shaft and is connected with the end cover; the inner bearing cover and the outer bearing cover are fixed to the inner shaft sleeve; the oil retainer is installed between the bearing and the outer bearing cover; the oil flinger is installed on the shaft; the first insulating plate is fixed between the inner bearing cover and the inner shaft sleeve; the insulating bonding layer is fixed between the inner shaft sleeve and the bearing sleeve; the second insulating plate is fixed between the inner shaft sleeve and the outer bearing cover; and the insulating casing pipe is arranged on an inner hole of the bearing sleeve in a sleeving manner. The insulation structure is simple. The bearing assembly is provided with the insulation structure, so that the generation of shaft current can be prevented during operation of a motor, the shaft current circuit is cut off, the problems that the electro-corrosion of the shaft and the bearing caused by the shaft current results in damage of the motor are prevented and the service life of the motor is prolonged.
Description
Technical field: the utility model relates to a kind of insulation system of bearing assemble.
Background technology: at present, domestic adjustable frequency motor demand is increasing, when motor is powered by frequency convertor system, motor reel easily produces axial compression and falls, in the time that forming loop, the parts such as axle, bearing, bearing holder (housing, cover), support just form shaft current, axle and the bearing of shaft current to motor causes galvano-cautery, cause motor to damage, for preventing that motor reel electric current generation rolling bearing from adopting the insulation bearing of import more, its price is 4-5 times of common imported bearing price, and procurement cycle is long, motor price improves immediately, has increased user's financial burden.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of insulation system of bearing assemble is provided, when it has mainly solved motor and has been powered by frequency convertor system, motor reel easily produces axial compression and falls, in the time that forming loop, the parts such as axle, bearing, bearing holder (housing, cover), support just form shaft current, axle and the bearing of shaft current to motor causes galvano-cautery, causes the problems such as motor damage.The insulation system that the purpose of this utility model is achieved in that bearing assemble by: internal bearing cover, bearing, the first insulation board, axle inner sleeve, insulation adhesive linkage, end cap, bearing holder (housing, cover), insulating sleeve, the second insulation board, oil scraper ring, disc, bearing end cover, axle form.Bearing is arranged on axle, and be connected with end cap by axle inner sleeve, internal bearing cover and bearing end cover are bolted in axle and put, oil scraper ring is arranged between bearing and bearing end cover, disc is arranged on axle, and the first insulation board is fixed in the middle of internal bearing cover and axle inner sleeve, and insulation adhesive linkage is fixed in the middle of axle inner sleeve and bearing holder (housing, cover), the second insulation board is fixed in the middle of axle inner sleeve and bearing end cover, and insulating sleeve is sleeved on the endoporus of bearing holder (housing, cover).This product structure is simple, reasonable in design, because bearing assemble is with insulation system, in motor when operation, can prevent that shaft current from producing, and has blocked shaft current loop, the axle of having avoided shaft current to produce causing and the galvano-cautery of bearing, cause the problems such as motor damage, improved the useful life of motor, the insulation bearing of the alternative import of this product, has reduced manufacturing cycle and the production cost of motor.
