Motion guiding device and cover body used in motion guiding device

Abstract

The invention provides a motion guiding device and a cover body. The motion guiding device is provided with a supporting body and a moving body, the moving body is provided with a moving body main body and the cover body, and direction switching ways used for allowing rolling bodies to achieve direction switching are arranged in the motion guiding device; the cover body is provided with an oil supply portion, a first oil way, a second oil way and an oil way separating mechanism; the first oil way is used for enabling the oil supply portion to communicate with the direction switching way located on any one of a left foot and a right foot of the cover body; the second oil way is used for enabling the oil supply portion to communicate with the direction switching way located on the other oneof the left foot and the right foot of the cover body; and the oil way separating mechanism is used for enabling the first oil way and the second oil way to be separated. According to the motion guiding device, the oil way separating mechanism is arranged, when the motion guiding device is used in the postures such as wall hanging and inclining, the problem that lubricating oil is difficult to arrive at the oil way close to the upper portion due to influences of the gravity can be solved, the good lubricating effect can be achieved, and then long life and long-term free maintenance of the motion guiding device can be achieved.

Description

technical field [0001] The present invention relates to a motion guide device and a cover used in the motion guide device, and more specifically, to a motion guide device including a cover provided with an oil supply portion, and the cover. Background technique [0002] A linear guide rail as one type of motion guide device includes a rail as a support body and a moving block as a moving body attached so as to be movable along the rail. A plurality of rolling balls capable of rolling motion are provided between the rail and the moving block. A plurality of balls circulate in an annular ball circulation path, and the ball circulation path includes: a ball rolling groove provided on the rail and a load ball provided on the moving block and facing the ball rolling groove provided on the rail The load rolling path constituted by rolling grooves, the unloaded path provided on the moving block and parallel to the loaded rolling path, and the U-shaped direction change path provide...

AI Technical Summary

Problems solved by technology

[0006] First of all, it is difficult to reduce the size and compactness of the linear guide because it is necessary to form a recess on the end cover plate for inserting the oil passage unit.

[0007] Secondly, since a plurality of oil passages are respectively formed on the end cover plate and the oil passage unit, the structure of the oil passage becomes complicated
