Abstract
The invention relates to an improved structure for a bearing cover of a box. The improved structure comprises a bearing cover body, wherein an oil return groove is formed below the bearing cover body; an included angle of -30 DEG C to -60 DEG C is formed between a central line of the oil return groove and a horizontal line; and distance between the top of the oil return groove and the center of the bearing cover body is 85 to 90mm. The improved structure for the bearing cover of the box has the advantages that by forming the oil return groove on the bearing cover body, oil at an oil seal of the bearing cover is drained through the oil return groove after the bearing cover and a box body are assembled, so a using effect of the box is improved, the structure is simple, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of casing bearing cap and improve structure.
Background technique
Casing is the important composition parts of retarder, and it is the pedestal of driving parts, and is as shown in Figure 1; Existing casing body 1 does not have spill port with the bearing cap joint; Casing exists casing body 1 and bearing cap joint bearing cap oil sealing oil leakage phenomenon after assembling is accomplished like this, and using effect is poor; Anti-revisionist troublesome poeration, manufacturing efficiency is low.
Summary of the invention
The technical problem that the present invention will solve is that existing casing bearing cap exists the oil sealing oil leakage phenomenon, and using effect is poor, thereby provides a kind of casing to improve structure.
In order to solve the problems of the technologies described above; The present invention realizes through following technological scheme: a kind of casing bearing cap improves structure; Comprise the bearing cap body; The below of said bearing cap body is provided with oil-return groove, and the center line of said oil-return groove becomes-30 °～-60 ° angles to be provided with horizontal line, and the centre distance of the top of said oil-return groove and bearing cap body is 85～90mm.
Preferably, the center line of said oil-return groove becomes-40 ° of angles to be provided with horizontal line, and the centre distance of the top of said oil-return groove and bearing cap body is 87mm, and performance is best, and using effect is good.
Preferably, said oil-return groove groove width is 12～16mm, and is simple in structure, easy to use, easy to process.
Preferably, said oil-return groove groove width is 14mm, and using effect is best, and is simple in structure, easy to process.
Preferably, the front end of said oil-return groove is provided with circular arc, and is simple in structure, and using effect is good.
In sum, advantage of the present invention: be provided with oil-return groove through the bearing cap body, bearing cap and casing body are installed after, the oil at bearing cap oil sealing place is discharged through oil-return groove, improved the using effect of casing, simple in structure, improved manufacturing efficiency.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 is the structural representation of existing bearing cap;
Fig. 2 is the structural representation of bearing cap of the present invention;
Fig. 3 is the structural representation of D-D among Fig. 2.
Embodiment
Like Fig. 2, shown in Figure 3, a kind of casing bearing cap improves structure, comprises bearing cap body 1, and the below of said bearing cap body 1 is provided with oil-return groove 2; The center line of said oil-return groove 2 becomes-30 °～-60 ° angles to be provided with horizontal line, the centre distance of the top of said oil-return groove 2 and bearing cap body 1 is 85～90mm, and the center line of said oil-return groove 2 becomes-40 ° of angles to be provided with horizontal line, and the centre distance of the top of said oil-return groove 2 and bearing cap body 1 is 87mm; Performance is best, and using effect is good, and said oil-return groove 2 groove widths are 12～16mm, and are simple in structure; Easy to use, easy to process, said oil-return groove 2 groove widths are 14mm; Using effect is best, and is simple in structure, easy to process; The front end of said oil-return groove 2 is provided with circular arc, and is simple in structure, and using effect is good.
With the bearing cap body 1 that is provided with oil-return groove 2 with after casing cooperates, casing work, the oil pressure of casing and bearing cap joint is discharged through oil-return groove 2.
Be provided with oil-return groove through the bearing cap body, bearing cap and casing body are installed after, the oil at bearing cap oil sealing place is discharged through oil-return groove, improved the using effect of casing, simple in structure, improved manufacturing efficiency.
