High-bearing capacity, high revolving speed, low friction angular contact ball bearing meet the needs of precision machine tool, and substitute import.
Utility model content
To solve problems of the prior art, the utility model provides a kind of angular contact ball axis with layer rolling body
It holds.
The technical solution adopted in the utility model is:
A kind of angular contact ball bearing with layer rolling body, in the bearing outer ring being arranged successively including ecto-entad, bearing
Circle and bearing inner race are equipped with outer rolling body, the bearing centre circle and the axis between the bearing outer ring and the bearing centre circle
It holds and is equipped with interior rolling element between inner ring, between the bearing outer ring and the bearing centre circle and the bearing centre circle and the axis
Hold the retainer being equipped between inner ring for the outer rolling body and the interior rolling element to be auxiliarily fixed;The bearing centre circle
Outer ring trajectory uses " interior fore shaft " form, and the inner ring trajectory of the bearing centre circle uses " outer fore shaft " form.
When in use, on the high-speed rotating main shaft such as the main shaft of machining center and numerically controlled lathe, bearing is in rotary course
There are rolling friction and sliding friction, rise since the heat that rolling friction and sliding friction generate makes bearing splash, so can successively band
Dynamic bearing inner ring, interior rolling element, bearing centre circle, the rotation of outer rolling body;In the course of rotation, interior rolling element and outer rolling item are received
The frictional force arrived is different, just will appear and is alternately rotated, so that interior rolling element and outer rolling body can mutually rest, and reduce heat
Amount, the service life is longer to reach, revolving speed height and the big advantage of bearing capacity.
Preferably, the outer rolling body is located at same level along the radial direction of bearing with the interior rolling element.So that
The pattern of bearing is different, is suitable for different situations.
Preferably, the outer rolling body is located at different level along the radial direction of bearing with the interior rolling element.So that
The pattern of bearing is different, is suitable for different situations.
Preferably, the outer rolling body and the interior rolling element are steel ball.Steel ball bearing load is big, so that bearing makes
Increased with the service life.
Preferably, the retainer is annular shape, and multiple circular holes are evenly distributed on the outer wall of retainer.It is easily installed
Interior rolling element and outer rolling body, so that interior rolling element and outer rolling body roll on scheduled trajectory.
The utility model has the beneficial effects that:
1, when in use, on the high-speed rotating main shaft such as the main shaft of machining center and numerically controlled lathe, bearing is in rotary course
In have rolling friction and sliding friction, rise since the heat that rolling friction and sliding friction generate makes bearing splash, so can be successively
Drive bearing inner race, interior rolling element, bearing centre circle, the rotation of outer rolling body;In the course of rotation, interior rolling element and outer rolling item
The frictional force received is different, just will appear and is alternately rotated, so that interior rolling element and outer rolling body can mutually rest, and reduce
Heat, the service life is longer to reach, revolving speed height and the big advantage of bearing capacity.
2, outer rolling body is located at same level along the radial direction of bearing with interior rolling element.So that the pattern of bearing is not
One, it is suitable for different situations.
3, outer rolling body is located at different level along the radial direction of bearing with interior rolling element.So that the pattern of bearing is not
One, it is suitable for different situations.
4, the material of outer rolling body and interior rolling element is steel ball material.Steel ball bearing load is big, so that bearing uses the longevity
Life increases.
5, it is easily installed interior rolling element and outer rolling body, so that interior rolling element and outer rolling body roll on scheduled trajectory
It is dynamic.
