Description

High-load U-shaped roller sliding bearing Technical Field The utility model belongs to the technical field of sliding bearings, and particularly relates to a high-load U-shaped roller sliding bearing. Background The existing linear guide rail system mostly adopts a ball circulation structure, which is easy to generate noise during high-speed operation, relies on lubrication to maintain durability, and remarkably reduces the service life of a bearing in a dust environment. In the prior art, a heavy-load roller slider with a patent publication number of CN216077966U 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, the roller surface is contacted with the surface of the guide rail, a follower is bolted in a follower rolling hole of the slider, the follower surface and the surface of the guide rail are in rolling contact with each other in a certain angle to form two groups, so that the whole slider is prevented from falling off the guide rail, the followers on the two sides of the slider are in rolling contact with the surface of the guide rail from three directions, the roller is in line-to-line contact with the guide rail, the contact area is larger, the limit load is allowed to be higher, the problem that the steel ball is in dotted line contact with the guide rail, the contact area is too small, and the load is smaller still exists in practical use. Therefore, a high-load U-shaped roller sliding bearing is needed, and the problems that foreign matters cannot be effectively prevented from entering the sliding block and running stability of a roller pin cannot be guaranteed in the prior art are solved. Disclosure of utility model The utility model aims to provide a high-load U-shaped roller sliding bearing so as to solve the problems in the background art. The U-shaped roller sliding bearing comprises a cylindrical guide rail and a sliding block body, wherein the sliding block body is arranged on the cylindrical guide rail in a sliding mode, supporting surfaces are arranged on the left side and the right side of the sliding block body, sealing elements are arranged on the sliding block body through the supporting surfaces, a first roller bearing is arranged on the upper portion of the sliding block body and used for bearing the load of the sliding block body, a roller pin is rotatably arranged on the first roller bearing, a bearing is arranged between the roller pin and the first roller bearing, the roller pin is correspondingly arranged on the sliding block body and provided with a slot, the roller pin is arranged in the sliding block body through the slot, locking screws used for locking the roller pin are arranged at the outer ends of the roller pin on the sliding block body, second roller bearings are arranged on the outer side of the cylindrical guide rail and fixedly connected with fixing screws, and the bottom of the sliding block body is obliquely arranged. In the scheme, two first roller bearings are arranged on the upper portion of the sliding block body and are arranged at left and right intervals. It is further worth to describe that the second roller bearings are respectively arranged on the front side and the rear side of the bottom of the sliding block body. It should be further noted that, the first roller bearing and the second roller bearing are both needle bearings or CF bearings. As a preferred embodiment, the sealing element is arranged in a U-shaped structure and is covered outside the cylindrical guide rail by a support surface. Compared with the prior art, the high-load U-shaped roller sliding bearing provided by the utility model at least comprises the following beneficial effects: (1) Through the holding surface that sets up in slider body both sides, be convenient for install sealing member between slider body and cylinder guide rail, through the setting of sealing member, can improve the leakproofness between slider body and the cylinder guide rail to effectively prevent that the foreign matter from getting into in the slider body, sealing member passes through U type structure setting simultaneously, its cladding cylinder guide rail, makes the motion process of slider body more stable, and then improves its life. (2) Through the slot of matching kingpin installation that sets up on the slider body, be convenient for install the operation with first antifriction wheel bearing in slider body upper portion, provide high load bearing capacity through first antifriction wheel bearing setting, simultaneously through having set up locking screw at the kingpin tip to ensure that first antifriction wheel bearing's stable is fixed, further improved slider body operational stability and life.
