Two of the technical problems to be solved in the utility model is for motorcar air conditioner provides a kind of compact structure, small-sized, light weight, and easily the electromagnetic clutch of automobile air conditioner compressor of installing holds, and this bearing can bear axially and bearing capacity radially.
Three of the technical problems to be solved in the utility model provides a kind of selflubricating easy to maintenance, long-term, and electromagnetic clutch of automobile air conditioner compressor dustproof, favorable sealing property holds.
Be the technical problem that solves, the technical solution adopted in the utility model is:
A kind of electromagnetic clutch of automobile air conditioner compressor holds, adopt the double-row angular contact bal bearing structure, comprise bearing outer ring, inner ring, rolling element, retainer and seal ring, has the biserial rolling element, design has parallel two ditch raceways side by side to the internal diameter of bearing outer ring with the external diameter surface of bearing inner race, and the biserial rolling element is arranged in the biserial raceway groove.Two ditch raceways that bearing outer ring is parallel, the surface of contact in its cross section is the arc surface that rolling element matches.Be provided with the inner ring of the inner ring double channel that adapts with rolling element in the inside of rolling element.Also have the plastics retainer between outer ring raceway and the bear inner ring grooved railway, be positioned at the inner ring periphery and be provided with the shelves limit that adapts with rolling element.Line of action between rolling element and the raceway has 22-28 ° wrapping angle along point of contact common normal line direction and raceway interplanar.This bearing can bear two-way load, i.e. bearing capacity axially and radially.
Prevent dust for improving self-lubricating effect and guaranteeing, the clitellum shape groove is respectively arranged, in the clitellum shape groove at two ends, be provided with seal ring in the outside, two ends of bearing inner race and outer ring double channel.
As further improvement, described seal ring is skeleton rubber double-lip sealing ring, its outer endless belt band interference fit is in bearing outer ring raceway groove outside endless belt, at the main lip and the secondary lip that seal ring is " people " font that be provided with in interior week of skeleton, the secondary interlabial gap of seal ring is matched with the smooth external diameter shelves limit of inner ring, seals the light contact slip on external diameter shelves limit of main lip on every side, can guarantee that sealing is reliable, rotation is flexible and the bearing heat radiation is good, effectively stops leaking of bearing grease, and can stop the outside dirt to be invaded.
As further improvement, the sealing circle body of the free end of the sealing skeleton of described seal ring also is provided with annular breach with the main lip lip body intersection of sealing, can reduce the applying power of the main lip of sealing, thereby reduce its friction power loss, prolong the working life of lubricating grease in sealing position and the bearing.
The utility model beneficial effect is: adopt parallel biserial raceway groove, compact structure is simple, when having eliminated work such as adjusting play, pretension, interpolation lubricating grease when two bearing pack of tradition are combined in assembling to the influence of assembly quality.Product structurally has 25 ° wrapping angle, has axially and bearing capacity radially, improves the rotating power transmission efficiency of engine crankshaft, increasing traction.Owing to increased seal ring, good dustproof effect; Before seal ring is pressed into the bearing both sides, inject a kind of high temperature resistant, lubricating grease that greasy property is good to bearing inside, can make its lifelong selflubricating.
