Problems solved by technology

The manufacturing method of the linking retainer 41 needs to place the rolling assembly in the mold first and make it by injection of overmolding plastic. This method requires high requirements on the material properties and the performance of the injection machine, which relatively increases the manufacturing cost; and Due to its special manufacturing method, the rolling element is in close contact with the spacer block of the linking cage, so that the rolling resistance of the rolling element is too large; and the degree of freedom of steering of this linking cage is easily restricted excessively during reflow. , resulting in unsmooth rotation and affecting the fluency of movement

Embodiment Construction

[0029] In order to further understand the characteristics and technical content of the present invention, please refer to the following embodiments of the present invention. However, the embodiments and drawings are for illustration and reference only, and are not intended to limit the present invention.

[0030] figure 1 It is a three-dimensional view of the rolling element retainer of the present invention; it is known that the rolling element retainer of the present invention is mainly composed of two parts, a spacer 20 and a connecting ring 10, and the spacer 20 is used to separate the sliding assembly (not shown) Out) to reduce frictional resistance, and the connecting ring 10 is used to link the spacer 20; when it is assembled, one end of the connecting ring 10 is fixed on a spacer 20, and the other end of the connecting ring 10 is sleeved on another spacer 20 to form a spacer. The body 20 and the connecting ring 10 are alternately arranged and socketed to form a holdin...

Abstract

The present invention relates to a rolling element retainer. The rolling element retainer is mainly composed of a spacer and a connecting ring. The combination of the rolling element retainer parts is designed as a rotating pair structure. The structure of nesting and cooperating with the groove structure can greatly improve the function of the rolling element cage to turn up and down and turn left and right.

Description

technical field [0001] The present invention relates to a rolling element retainer, which is a retaining device for rolling components used in linear transmission components; generally speaking, linear transmission components are used in machine tools, electronics, automation equipment, semiconductor equipment and other mechanisms. Background technique [0002] In the linear transmission assembly of the prior art, the cage of the rolling assembly can be roughly divided into two types: the cage of the first design is a single body, and the cage of the other design is a design of connecting many single bodies. first as Figure 11 As shown, the sliding block fits on a rail and moves, the sliding block is provided with rolling assemblies 30 and a single retainer 40 is placed between the rolling assemblies 30 in sequence, so that the rolling assemblies 30 do not collide with each other. When assembling the linear transmission components using this design, it is necessary to place...
