Abstract
Axis positioning roller bearing, including inner ring, outer ring, multiple balls, retainer, 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 the first groove being inclined outwardly on the other end outer wall of inner ring, there is the outer ring block face to match with ball end block machine on the inner wall of outer ring one end, the outer ring other end has the second 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, multiple balls are respectively cylindrical roller,
There is block machine at its both ends respectively, is provided with ball spindle nose at the both ends of the surface center of ball.On the outer wall of inner ring one end with multiple rollings
There is inner ring block face in pearl end block machine matching part, has the first groove being inclined outwardly on the other end outer wall of inner ring, in outer ring
There is the outer ring block face to match with ball end block machine on the inner wall of one end, the outer ring other end has the second groove being inclined outwardly,
Convenient for bearing installation and removal.Retainer is made of two circle shape pieces and multiple connecting columns, and two circle shape pieces are arranged in parallel, and more
A connecting column is fixed between two circle shape pieces by setting position respectively.Two corresponding insides of circle shape piece, and it is located at
It is respectively equipped with ball spindle nose socket between every two connecting column, is equipped with locating slot in the inside of ball spindle nose socket.In ball axis
The outside of head socket, is fixed with rounded tabs, baffle end is plugged in locating slot, and multiple balls are respectively installed in two circle shapes
Between piece, and the ball spindle nose at both ends is plugged in respectively in ball spindle nose socket, and outer ring is set on the outer end face of multiple balls,
Inner ring is installed in the inside of multiple balls, and the block machine at multiple ball both ends respectively with inner ring block face and outer ring block face phase mutual connection
Touching.
When the utility model is used, it is noted that installation direction, the first groove and the second groove not on same side,
Two bearings when installing and using on an axis, will be symmetrically installed.Operating uses base at the baffle end of middle (center) bearing and locating slot
Originally it is not subject to external force.
The utility model has the advantages that: multiple balls use cylindrical roller, and center of circle positioning reduces retainer and multiple rollings
Sliding-frictional resistance between pearl, integral part the resistance of sliding friction can be reduced to it is minimum, with existing roller bearing phase
It is small to compare running resistance, energy and labour saving.Retainer is not easy abrasion deformation, by low temperature environment and lubrication oil starvation influenced it is smaller,
Further improve the limit revolution of bearing.Smooth running, noise is lower, is easily installed and dismantles, long service life.

Specific embodiment
Axis positioning roller bearing, including inner ring 1, outer ring 2, multiple balls 3, retainer 4, multiple balls 3 are respectively cylinder
There is block machine 5 at roller, both ends respectively, are provided with ball spindle nose 6 at the both ends of the surface center of ball 3.On the outer wall of 1 one end of inner ring
There is inner ring block face 7 with multiple 3 end block machine of ball, 5 matching parts, has first be inclined outwardly on the other end outer wall of inner ring 1
Groove 8, there is the outer ring block face 9 to match with 3 end block machine 5 of ball on the inner wall of 2 one end of outer ring, and 2 other end of outer ring is oriented
Second groove 10 of outer incline mounts and dismounts convenient for bearing.Retainer 4 is by two circle shape pieces 11 and 12 structure of multiple connecting columns
At, two circle shape pieces 11 are arranged in parallel, and multiple connecting columns 12 respectively by setting position be fixed at two circle shape pieces 11 it
Between.Two corresponding insides of circle shape piece 11, and ball spindle nose socket 13 is respectively equipped between every two connecting column 12,
The inside of ball spindle nose socket 13 is equipped with locating slot 15.In the outside of each ball spindle nose socket 13, rounded tabs 14 are fixed with,
Baffle end 16 is plugged in locating slot 15.Multiple balls 3 are respectively installed between two circle shape pieces 11, and the ball at both ends
Spindle nose 6 is plugged in respectively in ball spindle nose socket 13.Outer ring 2 is set on the outer end face of multiple balls 3, and inner ring 1 is installed in more
The inside of a ball 3, and the block machine 5 at 3 both ends of multiple balls contacts with each other with inner ring block face 7 and outer ring block face 9 respectively.
