Description

A kind of reinforced pivoting support bearing plastic-steel spacing block

Technical field

The utility model is related to a kind of spacing block, is isolated with plastic-steel especially with regard to a kind of reinforced pivoting support bearing Block.

Background technology

Pivoting support bearing is the nearly 40 years infant industry parts for worldwide growing up.It can hold simultaneously By combined loads such as axial load, radial load and tilting moments, be collect supporting, rotation, transmission and the several functions such as fixed in The large size bearing of the special construction of the whole body.Because there is pivoting support bearing itself compact conformation, guiding to rotate convenient, installation letter Just with safeguarding easy the features such as, therefore it is widely used in handling machinery, digger, constructional engineering machinery, harbour machinery, wind On the huge revolving devices such as power generating, Medical Devices, radar and missile launcher.

There is the different structural shapes such as monoblock type, segmented, spacing block formula in pivoting support bearing retainer.Existing skill In art, because revolving support spacing block is integral molded plastic shaping, therefore local wall thickness 1 is easily caused (as shown in figure 1, the circle of contact Represent thickest) it is excessive.When these positions after moulding, because shrinkage can produce shrinkage cavity or loose, cause partial wall The intensity decreases at thick 1 position, therefore in use the failure probability at the position is greater than pivoting support bearing spacing block On other positions.

The content of the invention

For the problems referred to above, the purpose of this utility model is to provide a kind of high reinforced pivoting support bearing of compression strength Use plastic-steel spacing block.

For achieving the above object, the utility model takes technical scheme below：A kind of reinforced pivoting support bearing modeling Steel spacing block, it is characterised in that：It includes isolation block body, is separately provided for putting in the both ends of the surface of the isolation block body The ball-and-socket of bearing ball is put, ball-and-socket is arranged symmetrically described in two；Ring skeleton is embedded with the middle part of the isolation block body.

The ring skeleton includes ring skeleton main body, through hole is provided centrally with the ring skeleton main body, in institute The both ends of the surface for stating ring skeleton main body are respectively arranged with the arcwall face matched with the ball-and-socket, in the ring skeleton main body The boss of injection positioning is provided with outer wall, the side of the boss is concordant with the wall outer surface for isolating block body.

The boss is annular boss.

The boss is spaced apart fan-shaped boss.

The isolation block body is in integrated injection molding with the ring skeleton.

Metal material of the ring skeleton using compression strength more than 100MPa is made.

Due to taking above technical scheme, it has advantages below to the utility model：1st, the utility model is provided with annular Skeleton, can eliminate the excessive phenomenon of isolation block body local wall thickness, so as to avoid the appearance of the defect such as shrinkage cavity, loose, Compression strength of the present utility model is high.2nd, metal material system of the utility model ring skeleton using compression strength more than 100MPa Into further increasing compression strength of the present utility model.3rd, the utility model is provided with ring skeleton main body, ring skeleton The both ends of the surface of main body are respectively arranged with the arcwall face being engaged with ball-and-socket, it is possible to increase the evenness of wall thickness of spacing block, so as to carry High compression strength of the present utility model.4th, the utility model is provided with boss on the outer wall of ring skeleton main body, in order to Position in a mold, be embedded in in mould when producing beneficial to ring skeleton, the utility model simple structure is easy to use, production Efficiency high.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and examples.

As shown in Figure 2 and Figure 3, the utility model proposes a kind of reinforced pivoting support bearing plastic-steel spacing block, it is wrapped Isolation block body 2 is included, is separately provided for placing the ball-and-socket 3 of bearing ball, two ball-and-sockets 3 in the both ends of the surface of isolation block body 2 It is arranged symmetrically.Ring skeleton 4 is embedded with the middle part of isolation block body 2, it is possible to increase the compression strength of isolation block body 2.

In above-described embodiment, as shown in Figure 4, Figure 5, ring skeleton 4 includes ring skeleton main body 41, in ring skeleton main body 41 are provided centrally with through hole 42.The arcwall face matched with ball-and-socket 3 is respectively arranged with the both ends of the surface of ring skeleton main body 41 43, it is possible to increase the evenness of wall thickness of isolation block body 2.Injection positioning is provided with the outer wall of ring skeleton main body 41 Annular boss 44.Wherein, the side of annular boss 44 is concordant with the wall outer surface for isolating block body 2.As shown in fig. 6, above-mentioned Annular boss 44 can also replace with the multiple fan-shaped boss 44 that ring is located on the outer wall of ring skeleton main body 41, and each sector is convex The side of platform 44 with the flush with outer surface for isolating block body 2.

In above-described embodiment, isolation block body 2 is in integrated injection molding with ring skeleton 4.

In above-described embodiment, metal material of the ring skeleton 4 using compression strength more than 100MPa is made.

As shown in Fig. 2 when using, the utility model is stuck between the two bearings ball of pivoting support bearing, two bearings Ball is located in two ball-and-sockets 3 of isolation block body 2.In the presence of ring skeleton 4, the isolation local wall thickness of block body 2 is eliminated Excessive phenomenon, so as to avoid the appearance of the defect such as shrinkage cavity, loose, while improve the compression strength of isolation block body 2.

The various embodiments described above are merely to illustrate the utility model, wherein the structure of each part, connected mode etc. all can be It is varied from, every equivalents carried out on the basis of technical solutions of the utility model and improvement should not be excluded Outside protection domain of the present utility model.
