Abstract

The utility model relates to a combination sliding bearing of a cross shaft universal coupling and belongs to a sliding bearing of the cross shaft universal coupling of a rolling machinery. A bearing cover and a bearing ring are fixedly connected by a bolt or a screw thread. A sliding bearing material bushing is embedded in the bearing ring. The combination sliding bearing of the cross shaft universal coupling has the advantages of novel and simple structure, reliable work, low manufacturing cost, improvement of reliability of the coupling, reduction of maintenance amount, improvement of bearing capacity of the bearing and improvement of transmission efficiency of the coupling. A radial seal groove is arranged on the bearing so as to make seal simpler and more reliable, reduce mechanical parts, reduce product cost and be convenient for maintenance of a cross shaft.

Description

A kind of combination journal bearing of cross-axle universal shaft coupling

Technical field

The utility model relates to the sliding bearing of the cross-axle universal shaft coupling that is applied to rolling machinery, is particularly useful for heavy load, impacts the cross-pin coupling bearing supporting of the transmission of power under the big situation.

Background technique

The transmission shaft of current metallurgy industry rolling machinery consumption maximum is a universal coupling with spider.What the cross shaft bearing of coupling all adopted is a glass type rolling bearing supporting.Because the specific applying working condition of rolling machinery, coupling is in higher loaded-up condition usually, and impact is bigger.Because the restriction of the usage space of coupling, cross axle and rolling bearing are difficult to reach working strength, life requirements, often shut down phenomenon because of the strength deficiency generation part loses efficacy in running.

The common failure form: circlip for hole fractures and comes off; Cross axle fractures; The contact surface overload of cross axle, bearer ring and bearing roller produces plastic indentation.For above-mentioned reasons, cause bearing failure to be deviate from; The bearing plastic indentation makes bearing produce bigger mill sassafras resistance, quickens the wearing and tearing and the accessory premature failure thereof of bearing, and the rolling mill temporary parking frequency is increased, and has reduced manufacturing efficiency, has increased the maintenance load of rolling mill, has improved the cost of production of steel rolling.

Summary of the invention

The utility model provides a kind of combination sliding axle of cross-axle universal shaft coupling, and fractureing with solution location circlip for hole comes off; Cross axle resistance to flexure deficiency; The not enough problem of rolling bearing contact strength.The technological scheme that the utility model is taked is: bearing cap is fixedlyed connected by bolt or screw thread with bearer ring.

A kind of mode of execution of the utility model is: inlay the material for sliding bearing axle bush in the bearer ring.

A kind of mode of execution of the utility model is: bearing cap is fixedlyed connected with positioning screwn with bearer ring.

The utility model has the advantages that novel structure, simple, reliable operation, low cost of manufacture has improved the reliability of coupling, reduces amount of maintenance.In the application process: come off when having avoided back-up ring to fracture owing to the annular groove support elastic back-up ring of combination bearing; Sliding supported condition has dwindled the design space, just can strengthen the axle journal of cross axle as required, increases the module of anti-bending section of cross axle; The crotch hole is corresponding can to diminish, and increases the intensity of crotch.Adopt sliding bearing, improve bearing load carrying capacity, improved the transmission efficiency of coupling.On bearing, make sealing more simple and reliable the radial seal trench design, reduced mechanical parts, reduced product cost, made things convenient for the maintenance of cross axle.

The utility model is used for can being installed in hot rolled steel machine, cold rolling mill, aluminium casting-rolling mill, double duo mill behind the coupling.Be used to carry out the transmission of torque on two rollers, three rollers, four rollers, six rollers, vertical mill, the y-type rolling mill.
