Abstract

The utility model discloses heavy-load roller slider content, a guide rail is arranged on a platform or a bracket, a roller is arranged in a long hole on the slider through a roller pin, the roller pin is fixed by a jackscrew and is not moved, the surface of the roller is contacted with the surface of the guide rail, a follower is bolted in a follower hole of the slider, the surface of the follower is in rolling contact with the surface of the guide rail, the followers are divided into two groups, the axes of the followers and the rollers form a certain angle to prevent the slider from falling off from the guide rail integrally, the followers and the rollers on two sides of the slider are in rolling contact with the surface of the guide rail from three directions, the rollers and the guide rail are in line-to-line contact, the contact area is larger, the allowable limit load is higher, and the problems that a steel ball and the guide rail are in point-line contact, and the contact area is too small, so that the load is smaller are solved.

Description

Heavy-load roller sliding block

Technical Field

The technology is suitable for the technical field of linear motion in the mechanical industry, and particularly relates to heavy-load roller slider content.

Background

Linear guide rail sliding block mechanisms are increasingly applied to various fields in the modern mechanical industry, and the requirements of high load, severe environment, high linear speed and the like are met. Most of the slide blocks in the market are steel ball circulation type slide blocks, the slide blocks in the type are not perfect mechanisms, the advantages of the slide blocks are not described, and the defects of the slide blocks are summarized corresponding to the special requirements: the steel ball directly contacts with the guide rail, so that the circulation path of the steel ball is open, and impurities such as sand and dust easily enter the circulation path of the steel ball to directly influence the normal circulation of the steel ball; the steel ball circulation path is mostly in a waist-round shape, and the steel balls can periodically impact the inner wall of the retainer and collide with each other in the circulation process to generate noise; the steel ball is in point-line contact with the guide rail, and the contact area is too small, so that the load range is smaller. The technology is disclosed in the specification: heavy load roller blocks.

Disclosure of Invention

The technology adopts a roller contact mode of a deep groove ball bearing mechanism. The rollers and the guide rail are in line-to-line contact, the contact area is large, and the allowable limit load is high. Sealing devices are arranged on two sides of a bearing of the roller, impurities such as sand and dust are not easy to invade into a circulation path of the steel ball, and the allowable speed is high.

The application discloses heavy load gyro wheel slider is by guide rail 1, slider 2, gyro wheel 3, follower 4, gyro wheel round pin 5, jackscrew 6 constitutes characterized by: the guide rail 1 is installed on a platform or a bracket according to practical application, the roller 3 is installed in a long hole 101 on the slide block 2 through a roller pin 5, the roller pin 5 is fixed by a jackscrew 6 and is not moved, the surface of the roller 3 is in surface contact with the guide rail 1, the follower 4 is bolted in a follower hole 102 of the slide block 2, the surface of the follower 4 is in rolling contact with the surface of the guide rail 1, the followers 4 are divided into two groups, the axes of the followers and the axes of the followers form a certain angle with each other to prevent the whole slide block 2 from falling off from the guide rail 1, and the followers 4 on two sides of the slide block 2 and the roller 3 roll in three directions to be in surface contact with the guide rail 1, so that the whole slide block 2 makes reciprocating linear motion upwards on the guide rail 1.

Detailed Description

The technology shown in fig. 1, 2 and 3 comprises a guide rail 1, a slide block 2, a roller 3, a follower 4, a roller pin 5 and a jackscrew 6, and is characterized in that: the guide rail 1 is installed on a platform or a bracket according to practical application, the roller 3 is installed in a long hole 101 on the slide block 2 through a roller pin 5, the roller pin 5 is fixed by a jackscrew 6 and is not moved, the surface of the roller 3 is in rolling contact with the surface of the guide rail 1, the follower 4 is bolted in a follower hole 102 of the slide block 2, the surface of the follower 4 is in rolling contact with the surface of the guide rail 1, the followers 4 are divided into two groups, the axes of the followers and the axes of the followers form a certain angle with each other to prevent the whole slide block 2 from falling off from the guide rail 1, and the followers 4 on two sides of the slide block 2 and the roller 3 are in rolling contact with the surface of the guide rail 1 from three directions, so that the whole slide block 2 can only do reciprocating linear motion upwards on the guide rail 1. The end surface shape, rectangle and opening circle of the slide block 2 are combined to form the outline shape similar to capital English letter 'C'.

Fig. 4 is another end face shape of the slider 2 according to the present technology, in which a rectangle and an open circle are combined to form a contour shape similar to the capital letter "K", and the shape has no substantial influence on the function.
