Abstract
The utility model discloses a kind of profile retainer, comprise the retainer body conically arranged, the inwall of one end that described retainer body diameter is little is provided with the draw-in groove with the coplanar setting of retainer body shaft axis.By adopting technique scheme, the inwall of retainer body arranges draw-in groove, projection with draw-in groove clamping is set on the bearing inner race coordinated with it of correspondence simultaneously, retainer body and bearing inner race is made to realize synchronous axial system by this structure, thus increase the angular velocity of roller centered by the shaft axis of bearing, roller and retainer body and roller and interior is reduced by increasing rolling friction, sliding friction between outer ring, thus optimize the using effect of bearing, extend the working life of bearing, aim to provide a kind of profile retainer, it has the sliding friction of minimizing bearing, the effect increasing bearing using effect and extend bearing working life.
Description
Technical field
The utility model relates to Bearing fittings field, and more particularly, it relates to a kind of profile retainer.
Background technique
Profile bearing is a kind of bearing that can bear radial load and single direction direction of axis line load.When bearing bears radial load, a direction of axis line component will be produced, so when the bearing needing another can bear direction of axis line power is in the other direction balanced, so be usually arranged to single-row tapered roller bearing.Existing profile bearing its by adopt retainer separate roller, make between retainer with inside and outside circle in being separated setting simultaneously, when this causes inner ring or outer ring rotating retainer and roller centered by the shaft axis of bearing on angular velocity cannot be consistent, i.e. inner ring or outer ring and roller and all there is sliding friction between retainer and roller, this friction that bearing is in use subject to is comparatively large, affects working life and the using effect of bearing.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of profile retainer that can reduce bearing sliding friction.
For achieving the above object, the utility model provides following technological scheme: a kind of profile retainer, comprise the retainer body conically arranged, the inwall of one end that described retainer body diameter is little is provided with draw-in groove that is multiple and the coplanar setting of retainer body shaft axis.
The utility model is set to further: described pocket numbers is set to multiple, and is evenly distributed on the inwall of retainer body around retainer body shaft axis.
By adopting technique scheme, the inwall of retainer body arranges draw-in groove, projection with draw-in groove clamping is set on the bearing inner race coordinated with it of correspondence simultaneously, retainer body and bearing inner race is made to realize synchronous axial system by this structure, thus increase the angular velocity of roller centered by the shaft axis of bearing, roller and retainer body and the sliding friction between roller and inside and outside circle is reduced by increasing rolling friction, thus optimize the using effect of bearing, extend the working life of bearing.
The utility model is set to further: one end end face that described retainer body diameter is little is provided with annular groove, described draw-in groove connected ring connected in star near inner wall position.
By adopting technique scheme, by the design of annular groove, corresponding cooperating structure is set on inner ring, retainer body and coordinating between inner ring can be made compacter, the connection between inner ring and retainer body can be made simultaneously more firm, strengthen the soundness of bearing.
The utility model is set to further: described retainer body is adopted made of plastic.
By adopting technique scheme, setting due to annular groove causes the installation between inner ring and retainer body comparatively difficult, retainer body or inner ring local deformation can be caused, therefore use the retainer body of plastic material can increase the pliability of retainer body, impaired when avoiding installing.
The utility model is set to further: described retainer body is circumferentially evenly distributed with some pocket holes, and be provided with dividing strip between described pocket hole, inside and outside described dividing strip, both sides are provided with stiffening rib.
By adopting technique scheme, stiffening rib is set to strengthen the working life of retainer body.
The utility model is set to further: described draw-in groove and stiffening rib one_to_one corresponding are arranged.
By adopting technique scheme, draw-in groove and stiffening rib being arranged on and same straight line avoiding draw-in groove arrange causing retainer body wall webbing thin soundness and working life affecting retainer body.
In sum, the utility model profile retainer has the sliding friction of minimizing bearing, the advantage increasing bearing using effect and extend bearing working life.
Accompanying drawing explanation
Fig. 1 is the structural representation of profile retainer;
Fig. 2 is the A portion enlarged view of Fig. 1.
Reference character: 1, retainer body; 2, pocket hole; 3, annular groove; 4, draw-in groove; 5, stiffening rib.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model profile retainer is described further.
Be illustrated in figure 1 a kind of mode of execution of a kind of profile of the utility model retainer, comprise the retainer body 1 that conically arranges and be evenly distributed on retainer body 1 some pocket holes 2 circumferentially, the inwall of described retainer is provided with the draw-in groove 4 of the coplanar setting of retainer body 1 shaft axis and described draw-in groove 4 is uniformly distributed around retainer body 1 shaft axis, described draw-in groove 4 is positioned at the little one end of retainer diameter.
One end end face that described retainer body 1 diameter is little is provided with annular groove 3, described draw-in groove 4 connected ring connected in star 3 near inner wall position, and this retainer body 1 is adopted made of plastic.
By adopting technique scheme, setting due to annular groove 3 causes the installation between inner ring and retainer body 1 comparatively difficult, retainer body 1 or inner ring local deformation can be caused, therefore use the retainer body 1 of plastic material can increase the pliability of retainer body 1, impaired when avoiding installing.
In addition, for being same as the dividing strip separating pocket hole 2 between described pocket hole 2, inside and outside described dividing strip, both sides are provided with stiffening rib 5, and described draw-in groove 4 and stiffening rib 5 one_to_one corresponding are arranged, and arrange stiffening rib 5 to strengthen the working life of retainer body 1; Draw-in groove 4 and stiffening rib 5 are arranged on simultaneously and same straight line avoid draw-in groove 4 arrange causing retainer body 1 wall thickness limit thin soundness and working life affecting retainer body 1.
By adopting technique scheme, the inwall of retainer body 1 arranges draw-in groove 4, projection with draw-in groove 4 clamping is set simultaneously on the bearing inner race coordinated with retainer body 1 of correspondence, retainer body 1 and bearing inner race is made to realize synchronous axial system by this structure, thus increase the angular velocity of roller centered by the shaft axis of bearing, roller and retainer body 1 and the sliding friction between roller and inside and outside circle is reduced by increasing rolling friction, thus optimize the using effect of bearing, extend the working life of bearing.Corresponding cooperating structure is set on inner ring by the design of annular groove 3 simultaneously, retainer body 1 and coordinating between inner ring can be made compacter, the connection between inner ring and retainer body 1 can be made simultaneously more firm, strengthen the soundness of bearing.
The above is preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
