The invention further aims to solve the technical problems that: the bearing bush is ensured to be suitable for working in a smaller space.
The utility model provides a spline housing and axle bush composite construction, establishes including spline housing and cover axle bush on the spline housing, spline housing and axle bush interference fit be equipped with on the spline housing and can be with the locking mechanical system of axle bush locking on the spline housing, according to such structure, replaced the bearing through the axle bush, reduce cost to be applicable to littleer space, application scope is wide, and through locking mechanical system's setting, make the axle bush can not appear the phenomenon of skidding on the spline housing, more practical, safety.
Furthermore, the locking mechanism comprises a ring arranged on the outer side of the lower end of the spline sleeve and used for supporting the bearing bush, a plurality of first threaded holes are uniformly distributed on the circumference of the lower surface of the ring in a penetrating manner, a first half threaded hole which is arranged by taking the first threaded hole as an axis is arranged on one side of the spline sleeve, a second half threaded hole which is arranged by taking the first threaded hole as an axis is arranged on the inner side of the bearing bush, the first half threaded hole and the second half threaded hole are matched to form a second threaded hole, and the spline sleeve and the bearing bush are matched and fixed with the first half threaded hole and the second threaded hole through screws.
Furthermore, an oil groove is formed in the outer side of the bearing bush along the circumference, and according to the structure, the oil groove is used for storing lubricating oil, so that when the bearing bush is matched with a foreign object in working rotation, the bearing bush is guaranteed to rotate smoothly, and the structure is simple and practical.
Furthermore, the diameter of the bearing bush is larger than or equal to that of the circular ring, so that the bearing bush is suitable for working in a smaller space, and the structure is simple, practical and convenient.
To sum up, the utility model discloses for its beneficial effect of prior art is:
the utility model discloses a spline housing and axle bush composite construction, through this structure, replaced the bearing through the axle bush, reduce cost to be applicable to littleer space, application scope is wide, and through locking mechanical system's setting, make the axle bush can not appear the phenomenon of skidding on the spline housing, more practicality, safety.
