Linear transmission device and assembly method of rolling module of linear transmission device

Abstract

The invention relates to a linear transmission device and an assembly method of a rolling module of the linear transmission device. The linear transmission device is a chained assembly formed by roll balls which enable the rolling module to be loaded into the front portion of a load route, a spacer and a connection. When the rolling module is assembled, the linear transmission device enables the rolling module to be loaded into the load route, then the connection which is connected with the spacer is drawn out, the connection and the spacer are damaged and separated so as to finish assembly of the rolling module, and a peculiar relict part is formed on the peripheral surface of the spacer; thus, assembling motions can be facilitated, and production and assembly efficiency are improved due to the fact that the chained assembly is finished by the rolling module which is to be loaded into the front portion of the load route.

Description

technical field [0001] The invention relates to a linear transmission device and an assembly method of a rolling module of the linear transmission device, which is related to the transmission device. Background technique [0002] The ball screw belongs to a well-developed transmission device industry. Between the screw and the nut in the ball screw, there are multiple rolling parts that are continuously rolling. Through the continuous rolling of the rolling parts and the rotation of the screw, Make a linear relative motion between the screw and the nut; [0003] In order to prevent the balls in the ball screw from colliding during the rolling process, a spacer is provided between the balls. The spacer separates the adjacent balls and ensures the rolling of the balls. Common balls 10 and spacers 11 such as figure 1 As shown, a spacer 11 is set between two balls 10, and the spacer 11 of each adjacent ball 10 is set as an arc surface 111 to correspond to the rolling action of...

[0003] In order to prevent the balls in the ball screw from colliding during the rolling process, a spacer is provided between the balls. The spacer separates adjacent balls and ensures the rolling of the balls. Common balls 10 and spacers 11 such as figure 1 As shown, a spacer 11 is arranged between two balls 10, and the spacer 11 of each adjacent ball 10 is set as an arc surface 111 to correspond to the rolling action of the ball 10, and the peripheral side of the spacer 11 is provided with a groove 112 , the spacer 11 is provided with elastic force by the slot 112, and the balls 10 can rotate smoothly. Although the spacer 11 can achieve the purpose of spacing the balls 10 and ensuring the rolling action, however, the spacer 11 and each ball 10 are separate individual components before being assembled into the ball screw. During assembly, the spacer 11 and the balls 10 must be installed one by one while the ball screw is rotating, which is troublesome to assemble;

[0004] In addition, please refer to figure 2 Shown is another common ball 20 and spacer 21, which has the same problem as the first common ball mentioned above. The spacer 21 and ball 20 are also separate components before being assembled into the ball screw, and must be assembled during assembly. It is very troublesome to assemble the spacers 21 and the balls 20 one by one;
