Low-speed self-lubrication high-temperature sliding bearing

Abstract

The invention discloses a low-speed self-lubrication high-temperature sliding bearing. The low-speed self-lubrication high-temperature sliding bearing comprises a fastening button, a shaft sleeve, anoil inlet, an outer seat, a retaining groove, a bottom plate, a positioning button, a bearing, a sleeve body, balls, a limiting ring and a retaining ring. The low-speed self-lubrication high-temperature sliding bearing has the beneficial effects that the balls in the limiting ring and the balls on one side of the retaining ring are of annular structures, and normal installation and use of the bearing cannot be influenced by all positions of the shaft sleeve; the annular inside diameter formed by the balls in the limiting ring is the same as the diameter of the bearing, and the friction betweenthe bearing and the shaft sleeve is minimum, so that the loss of movement is reduced; the annular diameter formed by the balls on one side of the retaining ring is greater than the diameter of the bearing, and the friction between the sleeve body and the outer seat is minimum, so that the loss of movement is reduced; one side of the retaining groove is of a right triangle structure, and the fastening button and the retaining groove can form an abutting structure after installation, so that more support force is supplied; and the interior of the outer seat is of a solid structure, the oil inlet is connected with the shaft sleeve in the outer seat, and lubricant can be applied to the bearing at any time during use, so that the service life of the bearing is prolonged.

Description

technical field [0001] The invention relates to a bearing, in particular to a low-speed self-lubricating high-temperature sliding bearing, which belongs to the field of mechanical parts. 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 during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into rolling bearings and sliding bearings. Rolling bearings have been standardized and serialized, but their radial size, vibration and noise are relatively large, and their price is also high, which does not meet the current requirements of low noise pollution, environmental protection and energy saving. Contents of the invention [0003] The object of the present invention is to provide a low-speed self-lubricating high-temperature sliding bearing in orde...
