Abstract
The utility model provides a plug-in type bearing holder, which pertains to the field of bearing parts and has a structure which is composed of an upper rack and a lower rack which are butt-jointed with each other; wherein both the upper rack and the lower rack have an annular structure, some equidistant semispherical notches are provided on one side of the annular structure, a protruding plug and a matching socket are provided between each two neighboring semispherical notches, each protruding plug of the upper rack is in plug-in connection with a socket of the lower rack while each socket of the upper rack is in plug-in connection with a plug of the lower rack, when integrated by the plug-in connection the upper rack and the lower rack have two matching semispherical notches from each forming an intact cylindrical through-hole, and a bearing ball is arranged in the through-hole. The structure prevents the relative radial displacement between the two racks; a pin hole which is vertical to the end surface of the annular structure is provided between the two semispherical notches of the upper rack and the lower rack. The structure above prevents the relative axial displacement between the two racks. Compared with the prior art, the plug-in type bearing holder of the utility model has the advantages of the rational structure, the low production cost and the long service life, etc.
Description
(1) technical field
The utility model relates to a kind of Bearing fittings, specifically a kind of joint and clinging type retainer.
(2) background technique
Retainer is a kind of structure accessory that is used on the bearing with the rigid bearing ball.The retainer of prior art mainly contains two kinds of combined type and docks, and the structure of fabricated structure and performance are ripe, but also have deficiency: because it is mainly based on copper product, so price is higher relatively; And because the density of copper is bigger, so the finished weight made from copper is relatively large, and the frictional force that makes bearing inside and bearing be mated between the part increases; The dock structure is made of two-part of mutual butt joint, because the surface of contact of dock structure is the plane, so inconsistent phenomenon in use easily takes place, causes damage of bearings, and working life is shorter relatively.
(3) summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, provides a kind of reasonable in design, simple in structure, easy to assembly, low cost of manufacture, working life relatively long joint and clinging type retainer.
The technological scheme that its technical problem that solves the utility model adopts is:
This joint and clinging type retainer, comprise upper frame and lower frame, upper frame and lower frame all are cirque structures, equidistant several semi-circular cut-out that has on one of them end face of cirque structure, the clamping groove that between two adjacent semi-circular cut-out, is provided with the clamping projection and matches with the clamping projection, the clamping projection of upper frame and the clamping groove of lower frame are connected together, the clamping groove of upper frame and the projection of lower frame are connected together, upper frame semi-circular cut-out after the clamping and lower frame semi-circular cut-out form a complete cylindrical hole, bearing ball just is arranged in this cylindrical hole, and upper frame after the clamping and lower frame have been avoided both radial misalignments effectively.
Above-mentioned joint and clinging type retainer, in order to reduce manufacture cost, the structure of upper frame and the structure of lower frame can be made identically, versatility when this has improved the product assembling has to a certain extent avoided upper frame structure and lower frame structure to select the mutual trouble that type brings of joining when assembling because of inequality giving.
Above-mentioned joint and clinging type retainer, also have between two semi-circular cut-out of its upper frame and lower frame and the perpendicular pin-and-hole of annulus end face, after upper frame and the lower frame clamping, two pin-and-holes form a through hole, fixing pin is arranged in this through hole and once more upper frame and lower frame is fixed, thereby has avoided axial displacement between the two effectively.
Joint and clinging type retainer of the present utility model compared with prior art, the beneficial effect that is produced is:
1) interface arrangment and bearing pin fixed structure have been adopted on the structure, so be difficult between two-part taking place inconsistent phenomenon, the working life of having improved bearing;
2) use glass fiber enhanced nylon engineering plastics Alloy instead of Copper material on the material, because the density of glass fiber enhanced nylon engineering plastics is 1/10 of copper approximately, so its weight reduces greatly, correspondingly frictional force also reduces thereupon;
3) used glass fiber enhanced nylon engineering plastics Alloy instead of Copper material on the price, greatly reduced cost of production, the amplitude of reduction is 50% of copper product approximately.
(4) description of drawings
Accompanying drawing 1 is the overall structure structural representation of model utility;
Accompanying drawing 2 is the upper frame or the lower frame structural representation of model utility.
Among the figure, 1-upper frame, 2-lower frame, 3-semi-circular cut-out, 4-clamping projection, 5-clamping groove, 6-pin-and-hole, 7-cylindrical hole, 8-through hole.
(5) embodiment
Below in conjunction with explaining below 1,2 pairs of a kind of joint and clinging type retainers works of the present utility model of accompanying drawing.
As shown in Figure 1, a kind of joint and clinging type retainer of the present utility model is made up of upper frame 1 and lower frame 2, and the structure of the structure of upper frame 1 and lower frame 2 is identical, is connected together between the two.
As shown in Figure 2, be that example is described with upper frame 1 or lower frame 2.
Upper frame 1 and lower frame 2 all are cirque structures, equidistant several semi-circular cut-out 3 that has on one of them end face of cirque structure, perforate quantity is decided with the bearing preparation process, the clamping groove 5 that between two adjacent semi-circular cut-out 3, is provided with clamping projection 4 and matches with clamping projection 4, the clamping projection 4 of upper frame 1 and the clamping groove 5 of lower frame 2 are connected together, the clamping groove 5 of upper frame 1 and the clamping projection 4 of lower frame 2 are connected together, and the semi-circular cut-out 3 of the upper frame 1 after the clamping and the semi-circular cut-out of lower frame 23 form a complete cylindrical hole 7.
Above-mentioned joint and clinging type retainer, also have the pin-and-hole 6 perpendicular between two semi-circular cut-out 3 of its upper frame 1 and lower frame 2 with the annulus end face, after upper frame 1 and lower frame 2 clampings, two pin-and-holes 6 form a through hole 8, fixing pin is arranged in this through hole 8 and once more upper frame 1 and lower frame 2 is fixed, thereby has avoided axial displacement between the two effectively.
A kind of its processing and fabricating of joint and clinging type retainer of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.Upper frame and lower frame all adopt glass fiber reinforced nylon material, form with Shooting Technique and process for machining manufacturing.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
