Problems solved by technology

The manufacturing method of this connection retainer 31 needs to place the rolling element 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 spacer between the rolling element and the link cage is in close contact, so that the friction resistance of the rolling element is too large to cause sliding

Embodiment Construction

[0033] The present invention provides a preferred embodiment, figure 1 It is a schematic diagram of the annular structure of the rolling element retainer of the present invention; wherein the rolling element (not shown) of the rolling element retainer 40 of the annular structure is an example of a ball, and the rolling element retainer 40 is mainly composed of a connecting belt 41 The spacers 42 are connected into a ring structure, and an end 43 is added on the connecting belt 41, so that the rolling elements placed at the edge ends of the rolling element holder 40 can be properly retained in the rolling element holder 40; When the rolling element holder 40 is installed with rolling elements, the rolling element retainer 40 is turned inward as shown by the arrow in the figure, and then the rolling elements are sequentially inserted to assemble a complete rolling element retaining device.

Abstract

The invention relates to a retainer for the rolling element. The retainer for the rolling element is mainly composed of the partition body and connective band. The connective band makes the partition body into an annular structure, which forms a holding space and in which the rolling element is kept to make the space of the retainer for the rolling element have elastic domain for adjustment. It reduces the frictional resistance to make the rolling element roll smoothly.

Description

technical field [0001] The present invention relates to a rolling element retainer, which is a rolling element retaining device used on linear transmission elements; generally speaking, linear transmission elements are applied to mechanisms such as machine tools, electronics, automation equipment, and semiconductor equipment. . Background technique [0002] In the linear transmission elements in the prior art, the cages of the rolling elements can be roughly divided into two types: the cage of the first design is a single individual, and the cage of the other design is a design of connecting many individual individuals. first as Figure 4 As shown, the sliding block 11 fits on a rail and moves, the sliding block 11 is provided with balls 20 and a single retainer 30 is placed between the balls 20 in order to prevent the balls 20 from colliding with each other. When assembling the linear transmission element using this design, it is necessary to place each rolling element and...
