Problems solved by technology

The supporting products of high-power motors have high speed and large radial force. If the shaft extension end adopts grease-lubricated medium-series cylindrical roller bearings, the allowable speed of the bearing is often lower than the working speed, causing the motor rotor to roll when it reaches the working speed. The heat generated by body friction cannot be taken away in time or because the grease cannot be replenished in time, the surface temperature of the rolling body rises, the grease-lubricated lubricating film is lost, and the bearing is burnt due to the formation of a non-bearing lubricating protective film

Abstract

The invention relates to a thin oil-lubricated bearing device for a horizontal motor. The thin oil-lubricated bearing device for the horizontal motor is characterized in that: a motor shaft is arranged in a bearing bush; a gasket, a respirator, a respiratory tube and an oil duct are arranged on an outer cover of a bearing; a fixed bearing retainer ring, the outer cover of the bearing, an inner cover of a bearing, and a semi-ring are arranged on the bearing bush; a fixed baffle plate is arranged on the inner cover of the bearing; and an outer cover oil throwing disk, a rolling bearing, a round nut, a sleeve and an inner cover oil throwing disk are fixed on the motor shaft sequentially. The thin oil-lubricated bearing device for the horizontal motor has the advantages of completely guaranteeing the lubricating of the bearing of the horizontal motor with heavy load and high rotating speed due to thin oil lubrication and effectively improving the permissible working rotating speed of the motor bearing and prolonging the service life of the motor bearing, along with compact and reasonable structure.

Description

technical field [0001] The invention relates to a thin-oil-lubricated horizontal motor rolling bearing device, in particular to a thin-oil-lubricated rolling bearing device for some heavy-duty, high-speed horizontal motors. Background technique [0002] Lubrication is crucial to the normal operation of bearings. According to statistics, 80% of bearing failures are caused by various lubrication failures. The supporting products of high-power motors have high speed and large radial force. If the shaft extension end adopts grease-lubricated medium-series cylindrical roller bearings, the allowable speed of the bearing is often lower than the working speed, causing the motor rotor to roll when it reaches the working speed. The heat generated by body friction cannot be taken away in time or because the lubricating grease cannot be replenished in time, the surface temperature of the rolling body rises, the grease lubricated lubricating film is lost, and the bearing is burned withou...
