Abstract
Axis positioning roller bearing, including inner ring, outer ring, multiple balls, retainer, circlip, multiple balls are respectively cylindrical roller, and there are block machine and ball spindle nose in both ends respectively.There is inner ring block face on the outer wall of inner ring one end, there is annular groove on the other end outer wall of inner ring, circlip is fastened in annular groove, there is the outer ring block face to match with ball end block machine on the inner wall of outer ring one end, and the outer ring other end has the groove being inclined outwardly.It is enclosed at two on the retainer of shape piece and multiple connecting columns composition, is respectively equipped with ball spindle nose socket.In the outside of each ball spindle nose socket, it is fixed with rounded tabs.The advantages that the utility model has running resistance small, energy and labour saving, is influenced smaller by low temperature environment and lubrication oil starvation, further improves the limit revolution of bearing, be easily installed and dismantle, and smooth running, noise is lower, long service life.
Description
Technical field
The utility model relates to a kind of bearings, more particularly to a kind of changing to the rolling bearing structure with retainer
Into.
Background technique
Rolling bearing at present, ball majority are spheroidal and cylinder and are positioned by retainer that shortcoming is
In bearing rotation, the resistance that retainer contacts generation with ball is big, and energy consumption is big, and easy to wear, service life is short.
Utility model content
The technical problem to be solved by the utility model is to provide one kind to make full use of rolling friction, reduces sliding friction, adopts
With the designed retainer of the circle core shaft of ball positioning, the resistance of sliding friction is reduced to minimum, less energy-consuming, retainer is not easy
Abrasion deformation, the axis positioning roller bearing that can prolong the service life.
The technical solution adopted is that:
Axis positioning roller bearing, including inner ring, outer ring, multiple balls, retainer, circlip, multiple balls are respectively
There is block machine at cylindrical roller, both ends respectively, are provided with ball spindle nose at the both ends of the surface center of ball.On the outer wall of inner ring one end
There is inner ring block face with multiple ball end block machine matching parts, has annular groove, circlip on the other end outer wall of inner ring
It is fastened in annular groove, there is the outer ring block face to match with ball end block machine on the inner wall of outer ring one end, outer ring is another
There is the groove being inclined outwardly at end, and mounts and dismounts convenient for bearing.Retainer is made of two circle shape pieces and multiple connecting columns, and two
Circle shape piece is arranged in parallel, and multiple connecting columns are fixed between two circle shape pieces by setting position respectively.In two circle shapes
The corresponding inside of piece, and ball spindle nose socket is respectively equipped between every two connecting column, in the outside of ball spindle nose socket,
Rounded tabs are fixed with, multiple balls are respectively installed between two circle shape pieces, and the ball spindle nose at both ends is plugged in rolling respectively
In pearl spindle nose socket, outer ring is set on the outer end face of multiple balls, and inner ring is installed in the inside of multiple balls, and multiple balls
The block machine at both ends contacts with each other with inner ring block face and outer ring block face respectively.
When the utility model is used, it is noted that the direction of installation, the face of groove is with the face with circlip not same
Side, two bearings when installing and using on an axis, will be symmetrically installed.Operating is basic using the circlip above middle (center) bearing
It is not subject to external force.
The utility model has the advantages that: multiple balls use cylindrical roller, circle core shaft positioning, reduce retainer with it is multiple
Sliding-frictional resistance between ball, integral part the resistance of sliding friction can be reduced to it is minimum, with existing roller bearing
The running resistance that compares is small, energy and labour saving.Retainer is not easy abrasion deformation, by low temperature environment and lubrication oil starvation influenced compared with
It is small, further improve the limit revolution of bearing.Smooth running, noise is lower, is easily installed and dismantles, long service life.

Outer ring block face 10,2 other end of outer ring has the groove 11 being inclined outwardly, and mounts and dismounts convenient for bearing.Retainer 4 is enclosed by two
Shape piece 12 and multiple connecting columns 13 are constituted, and two circle shape pieces 12 are arranged in parallel, and multiple connecting columns 13 are solid by setting position respectively
It is fixed to be arranged between two circle shape pieces 12.Divide two corresponding insides of circle shape piece 12, and between every two connecting column 13
Not She You ball spindle nose socket 14 in the outside of each ball spindle nose socket 14 be fixed with rounded tabs 15, multiple balls 3
It is respectively installed between two circle shape pieces 12, and the ball spindle nose 7 at both ends is plugged in respectively in ball spindle nose socket 14.Outer ring 2
It is set on the outer end face of multiple balls 3, inner ring 1 is installed in the inside of multiple balls 3, and the block machine 6 at 3 both ends of multiple balls is divided
It does not contact with each other with inner ring block face 8 and outer ring block face 10.
