Description
Technical field
The present invention relates to a kind of tandems to assemble double-row angular contact bal bearing and its compound formulation.
Background technology
Angular contact ball bearing in practical applications, will generally assemble use, i.e., two sets, three sets of even more set angular contacts
Ball bearing is fitted in certain configuration mode and is used together, and basic group mode has back-to-back（That is the broadside end of two outer rings
Face is oppositely arranged）, face-to-face（That is the narrow side end face of two outer rings is oppositely arranged）And series connection（The narrow side end face of i.e. one outer ring with it is another
The broadside end face of one outer ring is oppositely arranged）.With specific reference to the needs of actual condition, select different group modes assembles axis
It holds.
General series connection assembles angular contact ball bearing mainly by inside and outside spacer ring by two sets of angular contact ball bearing series connection groups
With being formed together, two sets of angular contact ball bearings are respectively provided with inner ring, outer ring and the steel ball being located between Internal and external cycle, during use
Bearing is pre-tightened by outer ring spacer and cone spacer again and the loaded line of bearing is made to be mutually parallel.But this matched bearing lacks
Point is that the adjustment of client's pretightning force when in use is very cumbersome, and adjustment is improper to cause bearing life to shorten or even can not work
The phenomenon that.In addition, due to assembling the axial pre tightening force of angular contact ball bearing mainly by assembling the end-play of angular contact ball bearing
It determines, needs that the axial length of outer ring spacer and the axial length of cone spacer are ground and just can determine that end-play, due to adjusting
The technique of whole axial pre tightening force and grinding spacer ring is high to the technical merit requirement of worker and process is numerous and diverse, causes to assemble corner connection
The work period is long, efficiency is low when touching ball bearing installation.
Invention content
The present invention provides a kind of tandem and assembles double-row angular contact bal bearing, to solve use in the prior art
