Linear sliding rail

Abstract

A linear movement bearing comprises the slide track, slide base and multiple row sliding body. The slide base comprises the rigid, a base, outside edge front and rear end caps providing each row of each row of rolling return channel, seal plate and reinforcement plate. Outside the slide track and inside two rigid feet having four rows of corresponding tracks, with the base providing rolling return information channel inner side, and providing oil storage slot for each row of rolling body required lubricant, with oil block inside the oil storage slot, and the oil block contacting with the notch of the base to pass the lubricant to the rolling body. The oil storage slot has information channel that has oil delivery conditions to make up the lubricant. Two rigid reinforcement plates set outside the end cap, the fastening screw fastening the reinforcement palate on the slide base rigid through two end surfaces of the slide base, with the slide base end closer to the slide track inner side and lower part being able to fixed and reinforced.

Description

technical field [0001] The present invention is a linear slide rail design, including an axially extending slide rail, a slide seat, multiple rows of rolling elements and a lubrication system, the rolling elements are in the corresponding track of the slide seat and the slide rail and the circulation channel provided by the slide seat The internal circulation runs, and the lubrication system provides sufficient and long-term lubrication for the rolling elements. In order to increase the running speed of the linear slide rail, the present invention also provides a design for strengthening the strength of the end cover that provides the outer edge of the rolling track. Background technique [0002] A linear slide rail design, including a slide rail, at least one slide seat and multiple rows of rolling elements; the slide rail has axially extending tracks on the left and right outer sides or the upper side; the slide seat consists of at least one rigid body, front and rear end ...

Problems solved by technology

Among them, due to the complex shape of the channel, which may be 3D, it is difficult to cut or fill, or it is difficult to fill the fiber of the oil delivery material into the slender oil delivery pipe, especially when the oil delivery pipe is thinner.

[0003] On the other hand, since the end cover that provides the outer edge of the rolling channel is generally injection molded by plastic to form its complex shape, and is fixed to the two ends of the rigid body of the slider by screws, at the junction of the track load area and the rotary channel The end cover is limited by the slide track, and the outer edge of the turntable must be gradually reduced to prevent interference with the slide track. Therefore, it becomes the weakest part of the outer edge of the turntable, and is also limited by the height of the linear slide rail.

Generally, the lowermost turntable is designed to be close to the lower edge of the end cover, so the position of the fixing screw can only be designed at a distance from the junction of the track load area and the turntable and the lower edge of the end cover under space constraints, generally in the rigid body The upper edge of the two feet, so when the running speed of the sliding seat increases, the impact of the rolling element on the outer edge of the turning track also increases, and it is completely borne by the end cover. Damage; at the same time, the end cover is easily opened outward by the impact at the lower edge and the junction of the track load area and the turntable, causing the position of the turntable to change, and the rolling body is therefore not in a smooth cycle.

Generally, the sealing plate or oil storage device fixed on the outside of the end cover is only combined with the end cover, so the combination rigidity between the end cover and the rigid body of the slider cannot be increased.
