Abstract
For the deficiency overcoming existing rigid bearing to exist, this utility model provides a kind of rigid bearing, and this utility model includes LM optical axis, retainer, bearing holder (housing, cover), steel ball, sealing baffle；This rigid bearing simple in construction, production efficiency is high, steady quality, and bearing is conducive to large-scale production, and it is reliable, convenient to use, and assembling adaptability is good.
Description
Technical field
This utility model relates to a kind of mechanical devices field devices, especially a kind of simple in construction, steady quality, good sealing effect, excellent corrosion resistance, can make the rigid bearing extended service life.
Background technology
It is the size of power needed for shape that the rigidity of bearing refers to that bearing produces unit. the elastic deformation of rolling bearing is the least, most of machineries can consider, but in some machinery, such as machine tool chief axis, the rigidity of bearing is then a key factor, is normally applied cylinder roller bearing and taper roll bearing. because this two class bearing is when bearing load, its rolling element and raceway are linear contact lay, elastic deformation is little, good rigidly. and ball bearing is point cantact, and rigidity is poor.
At present, known rigid bearing structure is outer ring, inner ring, rolling element and retainer.This rigid bearing is yielding, poor rigidity, corrosion-resistant, and service life is low.
Summary of the invention
For the deficiency overcoming existing rigid bearing to exist, this utility model provides a kind of rigid bearing, this rigid bearing simple in construction, and production efficiency is high, steady quality, and bearing is conducive to large-scale production, and it is reliable, convenient to use, and assembling adaptability is good.
This utility model solves the technical scheme is that this utility model of its technical problem and includes LM optical axis, retainer, bearing holder (housing, cover), steel ball, sealing baffle.Bearing holder (housing, cover), sealing baffle opposite face are provided with the arc raceway encasing steel ball, and described LM optical axis is provided with the steel ball between bearing holder (housing, cover), sealing baffle and bearing holder (housing, cover), sealing baffle；Axial, radial direction during the assembling of this rigid bearing are in negative lash state.
This rigid bearing matches with tubing string shell and LM optical axis.
It is additionally provided with retainer between bearing holder (housing, cover), sealing baffle.
Steel ball is separated and is uniformly distributed by retainer.
The beneficial effects of the utility model are, simple in construction, and production efficiency is high, steady quality, and bearing is conducive to large-scale production, and it is reliable, convenient to use, and assembling adaptability is good.
