Abstract
The invention discloses a novel two-way thrust angular contact ball bearing, which comprises a steel ball, a bearing outer ring, a bearing inner ring and a grease feeding channel, wherein an inner rib and an outer rib are separately formed in the inner side and the outer side of the arc-shaped groove of the bearing outer ring; an arc-shaped groove is formed in the position where the bearing inner ring and the bearing outer ring are matched; an inner rib and an outer rib are separately formed in the inner side and the outer side of the arc-shaped groove of the bearing inner ring; the grease feeding channel feeding lubricating grease for the steel ball is formed in the bearing inner ring. The novel two-way thrust angular contact ball bearing has the beneficial effects that bearing grooves and the working face of the steel ball can be radiated, the sliding friction and the friction torque of the bearing are reduced and the work efficiency of the bearing is greatly increased.
Description
Technical field
The present invention relates to a kind of bearing, especially a kind of novel bidirectional angular contact thrust ball bearing.
Background technique
In lathe and machinery, the normal ball screw that uses is done transmission component, will rotatablely move and convert linear motion to, or change torque axis into axial repetitiousness active force.For obtaining highi degree of accuracy, high efficiency and reversible transmission effect, as the supporting structure of leading screw often need to bear simultaneously radial load, axially bidirectional load, with prefastening load and there is higher axial rigidity.Mostly traditional supporting means is with two covers or overlaps bearing more to be used in combination, utilize each shaft strength and bearing behavior share suffered load and obtain composite rigidity, but have the large and heating defect of axial rigidity deficiency or surface friction drag, and bearing apolegamy technical requirements is high, combination installation precision is difficult for guaranteeing; Have in recent years and adopt single cover biserial angle contacting thrust ball bearing as the application of leading screw supporting, can obtain higher axial rigidity and lower surface friction drag, but it is with two covers or to overlap bearing combined structure the same more, need to have special bearing mounting bracket (or bearing support), and high to bearing saddle bore required precision, difficulty of processing is large.In addition for preventing that cutting fluid, metal fillings and dust in lathe from entering, in bearing, damage bearing lubrication or cause stuck, need to applicable sealing and special lubrication system be set for the combination of every cover bearing or bearing, complex structure and uneconomical, the physical dimension that has simultaneously increased bearing bracket (or bearing support), has limited lathe and machinery towards less, compacter future development.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of effective, practical novel bidirectional angular contact thrust ball bearing is provided.
For achieving the above object, the present invention is achieved through the following technical solutions:
Novel bidirectional angular contact thrust ball bearing, comprise steel ball, bearing outer ring, bearing inner race and feed fat passage, it is characterized in that: described steel ball is arranged between bearing outer ring and bearing inner race and fixes with retainer, described bearing outer ring has respectively inner retaining side and outer rib in inner side and the outside of its circular arc raceway groove, described bearing inner race match with bearing outer ring position raceway groove not, described bearing inner race bottom is provided with the spacer ring that adopts two halves formula structure, and described bearing inner race below is provided with flange mounting hole.
In above-mentioned a kind of novel bidirectional angular contact thrust ball bearing, be provided with hello the fat passage of carrying lubricating grease to steel ball in described bearing outer ring, the described fat passage of feeding is provided with two oil filler plugs outward.
In above-mentioned a kind of novel bidirectional angular contact thrust ball bearing, the raceway groove that described bearing inner race matches with the circular arc raceway groove of bearing outer ring.
In above-mentioned a kind of novel bidirectional angular contact thrust ball bearing, the inner retaining side end face of described bearing outer ring and arc raceway groove inner retaining side and raceway groove tangent and bearing inner race is tangent.
In above-mentioned a kind of novel bidirectional angular contact thrust ball bearing, outer rib chamfering α is 50 degree～60 degree.
The invention has the beneficial effects as follows: novel bidirectional angular contact thrust ball bearing is dispelled the heat bearing channel and steel ball working face and reduces sliding friction and the friction torque of bearing, greatly improves the working efficiency of bearing.
