Description

Novel sliding bearing

Technical Field

The utility model relates to an industrial equipment bearing technical field, specific novel slide bearing that says so.

Background

The bearing has a vital function in mechanical design, has no replaceable function and is very wide in the related range. The rolling bearing developed on the basis of the bearing has the working principle that rolling friction replaces sliding friction, and generally comprises two ferrules, a group of rolling bodies and a retainer, and is a mechanical foundation part with strong universality, high standardization and high serialization. As various machines have different working conditions, various requirements are put forward on the aspects of load capacity, structure, service performance and the like of the rolling bearing. For this purpose, rolling bearings need to have various structures, including: deep groove ball bearings, self-aligning roller bearings, cylindrical roller bearings, tapered roller bearings, and the like. However, the most basic structure is made up of an inner race, an outer race, rolling elements and a cage — commonly referred to as four large pieces.

The rolling bearing mainly depends on a retainer to uniformly arrange rolling bodies between two rings for rolling motion, and the retainer not only uniformly separates the rolling bodies, but also guides the rolling bodies to rotate per se. When the two rings roll, the rolling body needs to bear large load and rotary friction force, so that the rolling body and the retainer are easy to deform and damage, and the service life of the rolling bearing is influenced. Meanwhile, when the rolling element and the retainer are deformed and damaged, the rolling bearing needs to be integrally replaced, which wastes time and labor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough that prior art exists, and provide a novel slide bearing.

In order to solve the technical problem, the utility model discloses a novel sliding bearing, including outer lane and inner circle, be provided with the annular sliding body between outer lane and the inner circle, the annular sliding body and outer lane and inner circle clearance fit.

Furthermore, a plurality of oil inlet grooves are uniformly formed in the inner side and the outer side of the annular sliding body respectively.

Furthermore, a plurality of first annular oil ducts are arranged on the inner side of the outer ring, and the first annular oil ducts are matched with the oil inlet grooves on the inner side of the annular sliding body.

Furthermore, a plurality of second annular oil ducts are arranged on the outer side of the inner ring, and the second annular oil ducts are matched with the oil inlet grooves on the outer side of the annular sliding body.

Further, the left and right sides of outer lane all is provided with the box dam, the box dam sets up the inboard at the outer lane, box dam and annular sliding body sliding connection.

Furthermore, the annular sliding body is made of wear-resistant and high-temperature-resistant materials.

To sum up, the utility model discloses following beneficial effect has:

the utility model discloses abandoned antifriction bearing's rolling element and holder, the substitute is the annular sliding body to sliding friction replaces rolling friction, because the annular sliding body slides and sets up between outer lane and inner circle, when the pivot was rotated, the annular sliding body received frictional resistance's influence can be followed the pivot and rotated the direction and rotate, can prevent that the annular sliding body part from bearing the load and excessively taking place deformation. Compared with the rolling body and the retainer, the annular sliding body eliminates the guide of the retainer to the rolling body and the rotation of the rolling body, has stronger bearing load capacity, is not easy to damage and has longer service life; the lubricating quality is improved by arranging the oil inlet groove, the annular oil duct I and the annular oil duct II, and the service life is further prolonged. When the utility model discloses a when the annular sliding body damaged, need not change whole bearing, only need to change the annular sliding body, convenient and fast, labour saving and time saving.
