Chain belt retainer of movable guide device

Abstract

The invention discloses a chain belt retainer of a movable guide device. The chain belt retainer is used for guiding a plurality of rolling bodies in the movable guide device; the rolling bodies are limited and guided by the chain belt retainer, so that the rolling bodies are incapable of separating from each other or being in overtaking collision with each other in a circulating channel in the movable guide device. The chain belt retainer comprises a strip-shaped flexible belt body, a plurality of rolling body receiving parts formed in the flexible belt body side by side and guide bodies arranged at two ends of the flexible belt body respectively, wherein each rolling body receiving part is used for receiving a rolling body; the diameter of the guide bodies is greater than the thickness of the flexible belt body and is smaller than or equal to the diameter of the rolling bodies; embedding parts which are butted with each other are respectively arranged on the guide bodies at two ends;the guide bodies can be connected with each other when the chain belt retainer is coiled until the head and the tail are butted with each other. According to the chain belt retainer of the movable guide device, the purpose of smoothly operating the rolling bodies is achieved through guidance of the guide bodies in the circulating channel.

Description

technical field [0001] The invention relates to a chain belt retainer for a mobile guide device, in particular to a mobile guide device installed and applied in the circulation channel of the mobile guide device to keep the rolling elements arranged and running in the circular channel chain strap holder. Background technique [0002] refer to figure 1 and figure 2 As shown, the current mobile guide device 20 (such as a linear slider or a ball nut) is used to slide and is arranged on a linear slide rail 40 or a screw rod 50, and is provided through the internal circulation channel 202 of the mobile guide device 20 Multiple rolling elements 30 (refer to image 3 and Figure 4 shown), so that the rolling body 30 rolls on the linear slide rail 40 or the screw rod 50, and then achieves the function that the moving guide device 20 rolls on the linear slide rail 40 or the screw rod 50 with low frictional resistance characteristics. This kind of moving guide device 20 is often...

Problems solved by technology

[0004] However, the width of the above-mentioned guide groove 203 is small, so that the side 102 of the chain belt holder 10 embedded in the guide groove 203 is easy to get stuck between the moving guide device 20 and the circulator 201 at both ends when sliding. At the seam A of the joint, the mobile guide device 20 cannot slide smoothly, and the chain belt retainer 10 will be broken if it is more serious.
