Embodiment Construction

[0015] Below, the substantive features and advantages of the present invention will be further described in conjunction with examples, but the present invention is not limited to the listed examples.

[0016] see Figure 1~2 As shown, the Figure 1~2 The structure of a radial heavy-duty roller linear guide pair provided by the embodiment of the present invention is shown. For ease of description, only parts related to the embodiments of the present invention are shown.

[0017] see Figure 1~2 , a radial heavy-duty roller linear guide pair, including a guide rail 1 and a slide seat 2, the upper part of the slide seat 2 is provided with a row of roller guide grooves and a row of upper raceways, and two rows of side rollers are symmetrically arranged on both sides. The roller 3 bearing the radial pressure load is set in the upper raceway, the roller 4 bearing the lateral pressure load is set in the side raceway through the cage 5, 6, and the rollers 3, 4 are both It is a cyl...

Abstract

The invention belongs to the technical field of linear guide rail pairs, and particularly relates to a radial heavy load type roller linear guide rail pair. The radial heavy load type roller linear guide rail pair comprises a guide rail and a sliding base. The upper portion of the sliding base is provided with a row of a roller guide groove and a row of an upper roller path, and two rows of lateral roller paths are symmetrically arranged on the two sides of the sliding base; rollers bearing radial pressure loads are arranged in the upper roller path, rollers bearing lateral pressure loads are arranged in the lateral roller paths through retainers, each roller is a circular cylinder with protruding shoulders at the two ends, and the rollers are in linear contact with the roller path face of the upper roller path and the roller path faces of the lateral roller paths. The rollers stably move in the roller paths and can bear acting force in all directions, abrasion of contact surfaces of the rollers and the roller paths is low, and thus the service life of the radial heavy load type roller linear guide rail pair is long. Compared with a traditional product, contact rigidity of the radial heavy load type roller linear guide rail pair is increased to about 5 times, and bearing capacity is increased to about 10 times.

Description

technical field [0001] The invention belongs to the technical field of linear guide rail pairs, and in particular relates to a radial heavy-duty roller linear guide rail pair. Background technique [0002] With the rapid development of CNC machine tools in the direction of large-scale, heavy-duty, high-speed, low-noise and fast-response, CNC gantry milling, CNC floor boring, large-scale machining centers, and large-scale special equipment urgently need rolling bearings with higher bearing capacity and stronger rigidity. The linear guide rail pair is matched with it. [0003] At present, the traditional ball linear guide is usually used in the machinery industry. Its structure is: the sliding seat and the guide rail each have four arc raceways, which are supported by balls, and the contact between the ball and the raceway surface is point contact. The advantages are small friction, high sensitivity and precision, and are suitable for small precision machine tools. The disad...
