Description

Technical Field

[0001] The utility model relates to the technical field of gear boxes, in particular to a universal bearing hole structure of a gear box. Background Art

[0002] Traditional gearbox bearing hole structure ( Figure 1 ) features: The bearing hole (right) is machined into a stepped hole (No. 11). When installing the shafting into a housing with a sub-boxed bearing hole, it can be lowered into the housing from the top down. The outer ring of the bearing (No. 3) is secured at both ends by the steps in the bearing hole and the stoppers in the cover (No. 2). The accuracy of the bearing assembly position is guaranteed by the dimension L in the bearing hole (right).

[0003] After assembly, if the bearing clearance is not adjusted properly, the cover (No. 2) or the bearing hole (No. 1) must be disassembled and reworked. Multiple disassembly and assembly of the cover (No. 2) will affect the shaft head seal, and reworking the housing will also take a certain amount of time, increasing processing costs. Summary of the Invention

[0004] In view of the above problems existing in the existing gearbox bearing hole structure, the present invention aims to provide a universal gearbox bearing hole structure which is simple to process, highly versatile and low in cost.

[0005] The specific technical solutions are as follows:

[0006] A universal gearbox bearing hole structure, comprising:

[0007] A bearing through hole is provided on the gear box body and is used for mounting a bearing;

[0008] a transparent cover, the transparent cover being detachably mounted on an open end of the bearing through hole and engaging with the bearing in the bearing through hole;

[0009] a spacer sleeve coaxially disposed in the bearing through hole and located on a side of the bearing facing away from the transparent cover, with one end of the spacer sleeve being in position-limiting engagement with the bearing;

[0010] A plurality of baffles are detachably mounted on the other open end of the bearing through hole and distributed along the circumference, and each of the baffles is limitedly matched with the other end of the spacer.

[0011] As a further improvement and optimization of this solution, each baffle is mounted on the box body by screws.

[0012] As a further improvement and optimization of this solution, two screws are provided between each baffle and the box body.

[0013] As a further improvement and optimization of this solution, the baffle is a rectangular structure.

[0014] As a further improvement and optimization of this solution, the plurality of baffles are distributed at equal intervals along the circumferential direction.

[0015] As a further improvement and optimization of this solution, the inner diameter of the spacer is larger than the inner diameter of the bearing.

[0016] As a further improvement and optimization of this solution, the transparent cover is mounted on the box body by a plurality of bolts, and the plurality of bolts are distributed at equal intervals along the circumference.

[0017] As a further improvement and optimization of this solution, a shaft sleeve is coaxially provided inside the transparent cover.

[0018] Compared with the prior art, the above technical solution has the following positive effects:

[0019] (1) When the shaft system is installed, the utility model first passes through the spacer sleeve and then passes through the bearing through hole on the housing. The outer ring of the bearing is fixed by installing a baffle on the housing to block the spacer sleeve, and the number or specification of the baffles can be adjusted according to the force conditions. At the same time, the bearing can be pre-assembled on the shaft system, and the bearing clearance can be adjusted by grinding the spacer sleeve. There is no need to repair the housing or the cover. When replacing bearings with different axial widths, only the spacer sleeve needs to be replaced, and there is no need to replace or reprocess the housing, which enhances the versatility and flexibility of the housing.

[0020] (2) The bearing through hole in the utility model is easier to process than the traditional bearing stepped hole, which saves processing time and improves processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
