Motion guide device and cover used in the same

Abstract

The invention provides a motion guiding device and a cover body. The motion guide device includes a support body and a movable body, the movable body has a movable body main body and a cover body, and a direction conversion path for changing the direction of the rolling elements is provided in the motion guide device, wherein the cover body is provided with: an oil supply part; The first oil passage communicates the oil supply portion with the direction changing passage located in either one of the left and right leg portions of the cover body; and the second oil passage connects the oil supply portion with the left and right leg portions of the cover body. The other direction changing passage communicates with each other; the oil passage separating mechanism separates the first oil passage and the second oil passage. Therefore, by providing the oil passage separation mechanism in the motion guide device, when the motion guide device is used in a wall-mounted or inclined posture, the problem that the lubricating oil is difficult to reach the upper oil passage due to the influence of gravity can be solved. A good lubricating effect can be obtained, so that the life of the motion guide device can be extended and maintenance-free for a long time.

Description

technical field [0001] The present invention relates to a motion guide device and a cover body used in the motion guide device, and more particularly, to a motion guide device including a cover body provided with an oil supply portion, and the cover body. Background technique [0002] A linear guide, which is one type of a 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 balls as rolling elements 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 A loaded rolling path formed of rolling grooves, an unloaded path provided on the moving block and parallel to the loaded rolling path, and a U-shaped dire...

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
