Abstract
The utility model relates to a kind of unilateral bearing mechanism, comprises inside casing, rotor and housing; Rotor is fixed between inside casing and housing; Rotor comprises several rotor blocks, and rotor block is arc, and the two ends of rotor block are inclined-plane, works in coordination in the inclined-plane between adjacent rotor block, and the corner cut of the relative housing side on one of them inclined-plane of rotor block is acute angle; On the inwall of housing, annular array is provided with some triangular grooves corresponding with rotor block acute angle bevel, and the cross section of triangular groove is obtuse angle or right-angled triangle; The utility model structure is simple, by the frictional force between inside casing and rotor, when rotating forward, rotor is under the drive of inside casing, rotate along housing, during reversion, inside casing makes the bevel edge of rotor snap onto in the groove of housing by frictional force, frictional force now between inside casing and rotor increases, and effectively prevents the direction of bearing from rotating.
Description
Technical field
The utility model relates to a kind of unilateral bearing mechanism, belongs to field of bearings.
Background technique
Traditional bearing is Double-directional rotary, in some special mechanical transmission mechanisms, need to be controlled sense of rotation by the limiting member of some sense of rotation, prevent the damage that mechanical reverse causes equipment, if a kind of bearing of single-direction transmission can be produced, can significantly elevating mechanism rotate time safety rate.
Model utility content
The technical problems to be solved in the utility model is: overcome the rotation of prior art middle (center) bearing and be two-way, the technical problem that cannot limit sense of rotation when some operating modes, provides a kind of unilateral bearing mechanism.
The utility model solves the technological scheme that its technical problem adopts:
A kind of unilateral bearing mechanism, comprises inside casing, rotor and housing; Described rotor is fixed between inside casing and housing;
Described rotor comprises several rotor blocks, and described rotor block is arc, and the two ends of rotor block are inclined-plane, works in coordination in the inclined-plane between adjacent rotor block, and the corner cut of the relative housing side on one of them inclined-plane of rotor block is acute angle;
On the inwall of described housing, annular array is provided with some triangular grooves corresponding with rotor block acute angle bevel, and the cross section of described triangular groove is obtuse angle or right-angled triangle.
As further innovation of the present utility model, on the periphery of described inside casing, annular array is provided with the projection of some right angle types, the right angle side of right angle type, towards the counter-rotational direction of bearing, is provided with the groove corresponding with described projection at described rotor block on a side of inside casing.
As further innovation of the present utility model, be provided with the curve bath that a radius is identical in the middle part of described rotor block, the elasticity garter spring be fixed on curve bath by between each rotor block is linked together.
As further innovation of the present utility model, the quantity of described triangular groove is the integral multiple of rotor block quantity.
As further innovation of the present utility model, described rotor block is copper.
The beneficial effects of the utility model are:
1, the utility model structure is simple, by the frictional force between inside casing and rotor, when rotating forward, rotor is under the drive of inside casing, rotate along housing, during reversion, inside casing makes the bevel edge of rotor snap onto in the groove of housing by frictional force, frictional force now between inside casing and rotor increases, and effectively prevents the direction of bearing from rotating.
2, spring ring of the present utility model can prevent bearing rotate time, cause because of the centrifugal force of rotor rotor repeatedly be embedded in groove, cause the instability that bearing rotates.
3, the projection of model utility and groove are worked in coordination, and can ensure that rotor is connected and common rotation with the stable of inside casing when rotating forward, and rotor ejection can be snapped in the groove of housing by rotor rapidly when reversion.
4, copper rotor stiffness reduce and also abrasion resistance high, effectively can prevent the infringement that rotor causes inside casing and housing after reversion for a long time.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is generalized section of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, the utility model is a kind of unilateral bearing mechanism, comprises inside casing 4, rotor and housing 1; Rotor is fixed between inside casing 4 and housing 1;
Rotor comprises several rotor blocks 2, and rotor block 2 is arc, and the two ends of rotor block 2 are inclined-plane, works in coordination in the inclined-plane between adjacent rotor block 2, and the corner cut of relative housing 1 side on one of them inclined-plane of rotor block 2 is acute angle;
On the inwall of housing 1, annular array is provided with some triangular grooves corresponding with rotor block 2 acute angle bevel, and the cross section of triangular groove is obtuse angle or right-angled triangle;
On the periphery of inside casing 4, annular array is provided with the projection of some right angle types, and the right angle side of right angle type, towards the counter-rotational direction of bearing, is provided with the groove corresponding with projection at rotor block 2 on a side of inside casing 4; Be provided with the curve bath that a radius is identical in the middle part of rotor block 2, the elasticity garter spring 3 be fixed on curve bath by between each rotor block 2 is linked together; The quantity of triangular groove is identical with rotor block 2 quantity, is 4; The material of rotor block 2 is copper;
When rotating forward, rotor is because the contractile force of elasticity garter spring 3, be close on inside casing 4, ring-shaped slide between the cylindrical of rotor and housing 1, during reversion, inside casing 4 reverses, the head of rotor is stressed, the other end of rotor is protruding, snap onto in triangular groove, realize stopping operating of bearing, prevent reversion from causing danger.
The progress of this structure has:
1, structure is simple, by the frictional force between inside casing and rotor, when rotating forward, rotor is under the drive of inside casing, rotate along housing, during reversion, inside casing makes the bevel edge of rotor snap onto in the groove of housing by frictional force, frictional force now between inside casing and rotor increases, and effectively prevents the direction of bearing from rotating.
2, spring ring can prevent bearing rotate time, cause because of the centrifugal force of rotor rotor repeatedly be embedded in groove, cause the instability that bearing rotates.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
