Abstract
The utility model discloses a fixed retainer type heavy-duty low-speed thrust ball bearing structure which comprises a heavy-duty shaft with shaft shoulders, a bearing seat cover and a retainer. The retainer is in an annular shape; the retainer and the bearing seat cover are sleeved on the heavy-duty shaft; the retainer is positioned between the shaft shoulders and the bearing seat cover and is fixed with the shaft shoulders; a plurality of steel ball holes are uniformly distributed on the retainer along the circumference; a steel ball is in a clearance fit with each steel ball hole; and one side of the steel ball is contacted with the shaft shoulders, and the other side is exposed out of the steel ball hole to support the inner end face of the bearing seat cover. When a shaft is combined with the bearing structure, a thrust ball bearing does not need to be additionally bought, and the cost is greatly reduced. In the fixed retainer type heavy-duty low-speed thrust ball bearing structure, only the retainer and the steel balls are utilized, therefore the production cost is further reduced, the structure is simple, the processing is convenient, and self-making can be realized.
Description
Technical field
The utility model relates to a kind of bearing structure, relates in particular to a kind of fixed retainer formula heavy-duty low-speed thrust ball bearing structure, the alternative traditional heavy-duty low-speed thrust ball bearing of this bearing structure.
Background technique
The seat ring that the thrust ball bearing of standard is assembled together by the blowout patche that is assembled together with axle, with bearing support and be spaced from each other and guide the retainer and the steel ball of steel ball motion to form equably the steel ball in the bearing.Retainer is stamped to form by mild-steel sheet, during work with steel ball at blowout patche and seat ring intercropping garden Zhou Yundong.Retainer has the certain precision requirement owing to complex-shaped, needs to make special-purpose punch die stamped, and makes single and mini-batch production cost of production costliness, and the manufacture cycle is longer.Particularly large-scale heavy duty low speed thrust ball bearing because application demand is wideless, makes that the Production of bearing cost is higher.In addition, in the process of assembling, existing thrust ball bearing all is earlier blowout patche to be inserted in the heavy duty axle when installing, drive fit is fixed in shaft shoulder place, again the pedestal cap interior edge face being pushed down seat ring fixes, when axle rotates, the bearing cage maintains static, the steel ball that is in the retainer can be rolled between blowout patche and seat ring, the shaft shoulder of end thrust formation and the sliding friction of bearing cage are converted into rolling friction, just cumbersome so when mounted, need thicker pedestal cap to hold seat ring, long axle has also increased mechanism's materials so that blowout patche to be installed.
The model utility content
The purpose of this utility model just is to provide a kind of fixed retainer formula heavy-duty low-speed thrust ball bearing structure of alternative heavy-duty low-speed thrust ball bearing, can effectively solve existing heavy-duty low-speed ball bearing manufacture cost height, processing and the problem that bothers is installed.
To achieve these goals, the technical solution adopted in the utility model is such: fixed retainer formula heavy-duty low-speed thrust ball bearing structure, the heavy duty axle, pedestal cap and the retainer that comprise the tape spool shoulder, described retainer is a ring-type, retainer and pedestal cap are enclosed within on the heavy duty axle, retainer is fixed between the shaft shoulder and pedestal cap and with the shaft shoulder, be uniformly distributed with some steel ball holes on the retainer along the circumference, be provided with a steel ball with gap fiting mode in each steel ball hole, steel ball one side contacts with the shaft shoulder, and another side exposes from steel ball hole and withstands on the pedestal cap interior edge face.
Described retainer is fixed by the sunk screw and the shaft shoulder.
Between steel ball and retainer, be filled with butter.
Described retainer thickness degree is less than steel ball size 2-5mm.
All become Spielpassung between described retainer and heavy duty axle and retainer and the pedestal cap.
Compared with prior art, advantage of the present utility model is: axle and bearing structure are combined, need not to buy in addition thrust ball bearing, cost is significantly reduced, this structure is only used retainer and steel ball, further reduces production costs, and is simple in structure, process very convenient, can realize the self-control.
Description of drawings
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is the structural representation of fixed retainer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment: referring to Fig. 1 and Fig. 2, the utility model fixed retainer formula heavy-duty low-speed thrust ball bearing structure, the heavy duty axle 1, pedestal cap 3 and the retainer 4 that comprise tape spool shoulder 2, described retainer 4 is a ring-type, retainer 4 and pedestal cap 3 all are enclosed within on the heavy duty axle 1, and retainer 4 is also fixing with the shaft shoulder 2 by sunk screw 7 between the shaft shoulder 2 and pedestal cap 3.Be uniformly distributed with some steel ball holes 5 along the circumference on retainer 4, be provided with a steel ball 6 with gap fiting mode in each steel ball hole 5, steel ball size and quantity are determined by Axial Thrust Calculation, be filled with butter between steel ball 6 and retainers 4.Steel ball 6 one side contacts with the shaft shoulder 2, and another side exposes from steel ball hole 5 and withstands on pedestal cap 3 interior edge faces.
Described retainer 4 is made by low-carbon steel thick plate, and described retainer thickness (being the steel ball hole degree of depth) is less than steel ball size 2-5mm.
All become Spielpassung between described retainer 4 and heavy duty axle 1 and the pedestal cap 3.
The utility model processing method with working principle is: attack the identical tapped hole of brill with retainer 4 on heavy duty axle 1 shaft shoulder 2, retainer 4 is inserted in heavy duty axle 1 back is fixed on the shaft shoulder with sunk screw 7, shaft shoulder external diameter is consistent with retainer 4 external diameters.Coat butter in retainer steel ball hole 5, then with in steel ball 6 embedded holes, cover upper ball cover seat makes the cage interior edge face just in time withstand steel ball 6.When heavy duty axle 1 slowly runs, the axial float of axle will be by steel ball 6 and the restriction of bearing cage interior edge face, by the steel ball 6 in retainer 4 steel ball holes 5, between 2 of the shaft shoulders and bearing cage interior edge face, roll, sliding friction between 2 of the shaft shoulders and pedestal cap 3 interior edge faces is transformed into rolling friction, reaches the effect same of standard heavy duty thrust ball bearing.
The utility model combines axle and bearing structure, need not to buy in addition thrust ball bearing, and cost significantly reduces, and this structure is only used retainer 4 and steel ball 6, has further reduced cost of production, and is simple in structure, process very convenient, can realize fully the self-control.
