Description

A kind of structure of using one direction thrust bearing

Technical field

The present invention relates to a kind of structure of using one direction thrust bearing.

Background technique

Thrust-bearing is to be used for bearing specially the special bearing of axial force, bear the bearing of the power of the direction parallel exactly with axle, thrust-bearing is merely able to bear axial load, one direction thrust bearing is the axial load that can only bear a direction, and double-direction thrust ball bearing can bear the axial load of both direction; Thrust-bearing can not restrictive axes radial displacement, limit speed is very low, single direction thrust ball bearing can restrictive axes and the axial displacement of a direction of housing, two-way bearing can limit the axial displacement of both direction.

General, bear the stressed structure of bi-directional axial, need to use doubledirection thrust bearing, its structure and installation are complicated, and cost is higher.

Summary of the invention

Goal of the invention: the objective of the invention is provides a kind of structure of using one direction thrust bearing in order to overcome the deficiency of existing product technology, and it is stressed to realize that one direction thrust bearing bears bi-directional axial.

Technological scheme: in order to solve the problems of the technologies described above, a kind of structure of using one direction thrust bearing provided by the invention comprises one direction thrust bearing, axle and bearing support, one direction thrust bearing is installed on the axle, and in the bearing support of packing into together, comprise that also an axial assembly apparatus is tight with on the axle, prevent one direction thrust bearing landing from the axle; Keep certain interval between described axial assembly apparatus and the one direction thrust bearing; Keep a fixed gap between one direction thrust bearing and the bearing support.

This axial assembly apparatus comprises axial trough divided ring, the collar and circlip for shaft; In two semicircle axial trough divided rings snap in groove on the axle from two relative directions; The collar that is complementary with axial trough divided ring profile is inserted in axle, and it is solid that two semicircle axial troughs are split ring set; Circlip for shaft is inserted in axial trough, and be fastened on the axle (1) on, with the collar in axial qualification.

Place, one direction thrust bearing rolling element center circle is between inner hole of bearing seat and axial trough divided ring cylindrical.

Axially interstice coverage is 0.03mm to 0.15mm between assembly apparatus and the one direction thrust bearing.

The space scope is 0.03mm to 0.15mm between one direction thrust bearing and the bearing support.

Described rolling element comprises ball roller, cylindrical roller, needle roller, tapered roller and spherical roller.

Beneficial effect: compared with prior art, a kind of structure of using one direction thrust bearing provided by the invention has the following advantages: the axial assembly apparatus that adopts axial trough divided ring, the collar and circlip for shaft structure, one direction thrust bearing is limited on the axle, it is stressed to realize that one direction thrust bearing bears bi-directional axial, it is simple in structure, easy for installation, provide cost savings simultaneously.

Embodiment

The present invention is described in further detail below in conjunction with drawings and Examples, should understand these embodiments and only be used to the present invention is described and be not used in and limit the scope of the invention.

A kind of structure of using one direction thrust bearing as shown in Figure 1 to Figure 3 comprises axle 1, one direction thrust bearing 2 and bearing support 6-1,6-2, and one direction thrust bearing 2 is installed on the axle 1, and in pack into together bearing support 6-1, the 6-2; Comprise that also an axial assembly apparatus is tight with on the axle 1, prevent one direction thrust bearing 2 landing from the axle 1; This axial assembly apparatus comprises axial trough divided ring 3, the collar 4 and circlip for shaft 5; Axially gap 8 scopes are 0.03mm to 0.15mm between assembly apparatus and the one direction thrust bearing 2.Space 7 scopes are 0.03mm to 0.15mm between one direction thrust bearing 2 and bearing support 6-1, the 6-2.

The rolling element 9 of described one direction thrust bearing 2 comprises ball roller, cylindrical roller, needle roller, tapered roller and spherical roller.Rolling element 9 shown in Figure 1 is shaped as sphere, and this single-direction balls bearing optimum position is that centre of sphere place circle is between bearing support 6-1,6-2 endoporus and axial trough divided ring 3 cylindricals.

As Fig. 4, two semicircle axial trough divided rings 3 shown in Figure 5, interior round width is greater than the cylindrical width, two semicircle axial trough divided rings 3 are snapped in groove on the axle 1 from two relative directions in; The face that axial trough divided ring 3 and one direction thrust bearing 2 are relative keeps 0.03mm to 0.15mm to the distance between the one direction thrust bearing 2.

The collar 4 its cylindrical width that are complementary with axial trough divided ring 3 profiles as shown in Figure 6 are greater than interior round width, and the collar 4 is inserted in axle 1, and two semicircle axial trough divided rings 3 covers are solid.

Circlip for shaft 5 as shown in Figure 7, be inserted in axial trough by using clasp forceps, and be fastened on the axle 1, and with the collar 4 in axial qualification, one direction thrust bearing 2 is limited on the axle 1, thereby it is stressed to realize that one direction thrust bearing 5 bears bi-directional axial.

The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
