Abstract
The rolling bearing of a kind of counter-rotation type, composite rolling body layout type, it is widely used in during various mechanical rotations, and serves and fix and effectively reduce load coefficient of friction.This bearing is made up of inner ring, outer ring, female rolling element, sub- rolling element and the part of retainer five.The effect of inner ring is to merge to rotate together with the axis with axle matching；Outer ring effect is engaged with bearing block, is played a supportive role；Female rolling element is to be evenly distributed in by means of the support of sub- rolling element between inner ring and outer ring, and bears the support force between inner ring and outer ring；Sub- rolling element reversely rotates between female rolling element, by female rolling element even partition, prevents female rolling element rubs mutually；Retainer plays positioning to sub- rolling element, guides sub- rolling element rotation and lubrication, it is ensured that sub- rolling element is consistent to bearing centre linear distance, prevents sub- rolling element from coming off.This bearing forms derotation campaign by sub- rolling element and female rolling element, and greatly reduces the friction of rolling element and retainer, reduces bearing heating amount, extends bearing life.
Description
(1) technical field：
New-type rolling bearing is the utility model is related to, suitable for various mechanical rotations, and plays fixed and more efficient reduction
Load coefficient of friction acts on.It is characterized in that with have in an array, female two kinds of reverse rotations rolling elements, female rolling element not with guarantor
Hold bridge joint to touch, coefficient of friction and caloric value are lower.
(2) background technology：
Conventional rolling bearing inner ring, outer ring, rolling element and the part of retainer five by being made up of.Rolling element is evenly distributed on
Between inside and outside circle, and it is kept frame and separates.Because inside and outside circle stress is inconsistent, cause each rolling element stress different, and direction
Inequality, the side of rolling element and retainer produce pressure, and form sliding friction.When rotating at a high speed, friction also produces pole simultaneously
Big heat, the life-span of bearing is produced a very large impact.
(3) content of the invention：
The purpose of this utility model is to provide a kind of new-type rolling bearing, is uniformly divided female rolling element by sub- rolling element
Every, female rolling element does not contact with retainer, sub- rolling element and female rolling element derotation campaign, so as to obtain lower coefficient of friction and
Caloric value, extend the service life of bearing.This bearing is by by inner ring, outer ring, female rolling element, sub- rolling element and the part of retainer five
Composition.The effect of inner ring is to merge to rotate together with the axis with axle matching；Outer ring effect is engaged with bearing block, is played support and is made
With；Female rolling element is to be evenly distributed in by means of the support of sub- rolling element between inner ring and outer ring, and bears inner ring and outer ring
Between support force；Sub- rolling element reversely rotates between female rolling element, by female rolling element even partition, prevents female rolling
Kinetoplast rubs mutually；Retainer plays positioning to sub- rolling element, guides sub- rolling element rotation and lubrication, it is ensured that sub- rolling element
It is consistent to bearing centre linear distance, prevents sub- rolling element from coming off.This bearing is formed instead by sub- rolling element and female rolling element
Rotation motion, and greatly reduce the friction of rolling element and retainer, bearing heating amount is reduced, extends bearing life.
(4) illustrate：
Fig. 1 is the structural representation of the utility model rolling bearing；
The label declaration of parts in Fig. 1：
1 outer ring；2 female rolling elements；3 sub- rolling elements；4 retainers；5 inner rings；
(5) embodiment：
In Fig. 1, female rolling element (2) is evenly distributed between outer ring (1) and inner ring (5), and is played a supporting role.
Female rolling element (2) according to 1: 1 ratio, is uniformly separated with female rolling element (2), by reversely rotating, reduced by sub- rolling element (3)
Rub and generate heat in rolling process.Sub- rolling element (3) is fixed between outer ring (1) and inner ring (5) by retainer (4), per height
Rolling element (3) is consistent to the distance of bearing axis, sub- rolling element (3) is not contacted with outer ring (1) and inner ring (5).
The utility model rolling bearing has the characteristics of smaller coefficient of friction, lower calorific value, long lifespan.
Claims (5)
