Abstract
Entitled a kind of commercial car penetrating bridge output end bearing of the invention.Belong to technical field of rolling bearings.It is mainly and solves the problems, such as that initial failure easily occurs in existing car transmissions spring bearing.It is mainly characterized by：Including by a flanged outer ring, steel ball and retainer between inner ring and outer ring and inner ring；Described inner ring is made up of two left half inner rings of separation, right half inner rings；Left half inner ring, right half inner ring and outer ring are 4 left half inner rings of angular contact bearing, right half inner ring and outer rings.The characteristics of present invention has long service life and reliability high, is mainly used in commercial car（Particularly engineering truck）Penetrating bridge output end is supported.
Description
Technical field
The invention belongs to technical field of rolling bearings, and in particular to it is a kind of for commercial car penetrating bridge output end support,
The commercial car penetrating bridge output end bearing of new construction.
Background technology
It is common deep groove ball bearing that commercial car penetrating bridge output end is supported usually used, as shown in figure 1, in practical application
During, ball bearing service life is short, and initial failure ratio is big, and failure mode is mainly with fragmentation and holding at the snap ring groove of outer ring
Frame is broken.
Analyzed by the output end insertion axle working order to penetrating bridge, in normal road, insertion axle is or not automobile
Axial force is born, now bearing is solely subjected to radial load.It is bad in overload, road conditions（Mine building site）, reversing etc. condition downward driving when
Cause that insertion axle spline pair flex is not smooth, now bearing has born axial force, make bearing that axial float or other strength to occur.
Bearing failure be mainly type selecting it is improper caused by, i.e., bearing capacity is not enough in itself for bearing, due to space limitation again
Larger sized bearing cannot be selected.First improvement simply will make flanged ball into stop groove bearing by deep groove ball bearing
Bearing, as shown in Figure 2.Solve the problems, such as outer ring fragmentation, but do not have solution retainer caused by strength problem of bidding farewell to fail.
The content of the invention
The purpose of the present invention is aiming at above-mentioned weak point, there is provided one kind can both improve bearing load carrying capacity, again may be used
Retainer fails caused by effectively solving because installing other strength, and greatly prolongs the commercial car penetrating bridge output end axle of service life
Hold.
Technical solution of the invention is：A kind of commercial car penetrating bridge exports end bearing, including flanged by one
Steel ball and retainer between outer ring, inner ring and outer ring and inner ring, it is characterized in that：Described inner ring is by two left sides for separation
Half inner ring, right half inner ring composition；And left half inner ring, right half inner ring and outer ring and steel ball are 4 angular contacts.
Left half inner ring described in technical solution of the invention, the contact angle between right half inner ring and steel ball are
20°±3°。
Outer ring described in technical solution of the invention is the outer ring being made up of plain bearing steel；Outer ring raceway is double
Circular arc raceway groove, it is desirable to ground with forming grinding wheel and processed.
Left half inner ring, right half inner ring described in technical solution of the invention of plain bearing steel by being made up；Left half
Bear inner ring grooved railway, right half bear inner ring grooved railway are single circular arc raceway groove.
Steel ball described in technical solution of the invention is the steel ball being made up of plain bearing steel.
Retainer described in technical solution of the invention is by common plasticses retainer.
The present invention has the positive effect that：
From 4 angular contact ball bearings that flanged pin outer ring and double inner rings are constituted, bearing load carrying capacity can be improved, carried
Outer ring intensity high, solves the problems, such as to install and use the other strength that causes and causes retainer to fail, and can bear larger axial impact
Load.Fact proved, improvement direction and result are correct, and bearing failure and claim is greatly reduced.
The characteristics of present invention has long service life and reliability high.Present invention is mainly used for commercial car（Particularly engineering
Car）Penetrating bridge output end is supported.
Brief description of the drawings
Fig. 1 often uses bearing arrangement for existing penetrating bridge output end.
Fig. 2 improves bearing arrangement for the first time for existing penetrating bridge output end.
Fig. 3 is penetrating bridge output end bearing arrangement of the present invention.
Specific embodiment
As shown in Figure 3.The present invention is a kind of commercial car penetrating bridge output end bearing, including an outer ring for flanged pin 2
1st, two left half inner rings 6 of separation, the steel balls 3 between right half inner ring 5 and outer ring 1 and left half inner ring 6, right half inner ring 5 and guarantors
Hold frame 4.Left half inner ring 6, right half inner ring 5 and outer ring 1 are 4 left half inner rings of angular contact bearing, right half inner ring and outer rings.Outward
Circle 1 is the outer ring being made up of the i.e. conventional use of bearing steel of plain bearing steel.The raceway groove of outer ring 1 be bicircular arcs raceway groove, it is desirable into
Molding sand disc sharpener is processed.Left half inner ring, right half inner ring by being made up of plain bearing steel such as bearing steel, left half bear inner ring grooved railway, the right side
Half bear inner ring grooved railway is single circular arc raceway groove.Steel ball 3 is the steel ball being made up of plain bearing steel such as bearing steel.Retainer is by common
Plastics such as plastic cage.Left half inner ring 6, the contact angle between right half inner ring 5 and steel ball 3 are 20 ° ± 3 °.From 4 corner connections
Ball bearing is touched, to improve bearing load carrying capacity and solve the problems, such as to install and use the other strength for causing.Fact proved, improvement direction and knot
Fruit is correct, and bearing failure and claim is greatly reduced.
