Sealed bearing

Abstract

The invention discloses a sealed bearing, which comprises an outer ring, an inner ring is movably connected to the surface of the inner wall of the outer ring, balls are movably connected between the outer ring and the inner ring, and balls are movably connected between the balls. A cage, the top of the outer ring is movably connected with a plug body, the bottom of the surface of the plug body is fixedly connected with a sealing sleeve, and a first sealing ring is movably connected between the outer ring and the inner ring and on the back of the ball, A first sound-insulating ring is movably connected between the outer ring and the inner ring and located on the back of the first sealing ring, and a first spring piece is movably connected between the outer ring and the inner ring and located on the back of the first sound-insulating ring. Through the cooperation of the sealing sleeve, the first sealing ring, the first spring leaf, the second sealing ring and the second spring leaf, the present invention solves the problem that the traditional detachable bearing cannot keep the lubricating grease in the bearing, and at the same time foreign sundries or dust It is easy to enter the bearing and affect the service life of the bearing.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a sealed bearing. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient (friction coefficient) during its movement, and ensure its rotation accuracy (accuracy). Due to the different friction properties, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and their prices are higher. Rolling bearings are generally It consists of four parts: outer ring, inner ring, rolling element and cage. In simple terms, as long as the outer ring, inner ring, and rolling element are present, it can be defined as a rolling bearing. According to the shape of the rolling element,...
