1. cover plate circle and the double chambers frame of turning must clean before bonding, guarantee the turbidity test of both junction planes, if clean untotally, just have that oils sticks in the hole, periphery and a junction plane, directly affect the adhesion strength of glue, both are easy to produce and separate when bearing working.
2. the consumption of bonding glue is difficult to control, it is insecure to have lacked easy bonding, and many glue overflow and flow into bearing cavity, can change the actual shape chamber of special-shaped slot, thereby the unobstructed rotation of the forward that directly affects voussoir and reverse locking performance can directly cause product rejection when serious.
3. by pin-and-hole band glue fixed bonding, must add glue in each hole, not only work difficulty is large, and manufacturing efficiency is low, especially must be bonding firmly through the natural coagulation ability of special time after the gluing, otherwise just can't guarantee bonding intensity, manufacture cycle is long, inefficiency.
4. environmental protection index is difficult to satisfy, raising along with the Environmental Protection in China requirement, bearing products is also proposed environmental requirement, especially markets such as Europe, the U.S., Japan, all need manufacturing enterprise to provide the survey reports such as SGS of harmful substances, in glue, contain many harmful materials, use glue to be adhesively fixed and be difficult to satisfy increasingly tight environmental requirement.
[model utility content]
In order to overcome the above-mentioned shortcoming that fixed structure exists that is adhesively fixed of retainer split in the existing Conjoined one-way rotating bearing, the purpose of this utility model provides a kind of Conjoined one-way rotating bearing seizing type retainer, its assembling is simple, and efficient is high, in conjunction with solid and reliable, cost is low, do not need to use glue, can guarantee the structure stability of Conjoined one-way rotating retainer, improve bearing working life, do not contain the material of harmful health, meet existing environmental requirement fully.
The technological scheme that the utility model is taked is as follows:
A kind of Conjoined one-way rotating bearing seizing type retainer, comprise cover plate circle and the double chambers frame of turning, a turn end of frame of double chambers is the steel ball end, the edge circumferentially evenly is provided with the steel ball cavity volume on the steel ball end, the turn the other end of frame of double chambers is binding end, the edge circumferentially is provided with wedge groove equably on binding end, spring groove and division post, division post is between two adjacent wedge groove, it is characterized in that: the edge circumferentially is provided with snap studs equably on the interior edge face of cover plate circle, be provided with the interlock barb of engaging plane and conical surface composition at the head of snap studs, the engaging plane is a to the distance of the interior edge face of cover plate circle, and the width of interlock barb is b; Be provided with the interlock hole at the turn end face of division post of frame of double chambers, the shape of cross section in interlock hole is monolateral step hole, epimere is patchhole, hypomere is step hole, intersection at patchhole and step hole forms occlusal surface, the shape size of patchhole is corresponding with snap studs head interlock barb, identical apart from a to the distance of binding end and engaging plane to the interior edge face of cover plate circle of occlusal surface, it is corresponding to be arranged on the turn interlock hole of binding end setting of frame of the quantity of the snap studs on the interior edge face of cover plate circle and distributing position and double chambers.
Further, on turning the end face of each division post of frame, double chambers is provided with the interlock hole.
Owing to changed cover plate circle and the double chambers assembly and connection mode between the frame of turning, abandoned relying on turn the gluing connecting structure be with between the positioning hole on the junction plane of frame of locating column on the cover plate circle and double chambers, adopt interlock barb and double chambers on the cover plate circle to turn and clamp occlusion structure between the interlock hole on the frame, not only be convenient to assembling and dismounting, and clamp in conjunction with rear reliable and stable, replace the glue structure that is adhesively fixed with buckle structure, overcome above-mentioned four point defects that existing separable assembled retainer exists.
