Lubricating device of self-lubricating sliding bearing

Abstract

The invention provides a lubricating device of a self-lubricating sliding bearing, and belongs to the technical field of bearing lubricating devices. The lubricating device comprises a sliding bearingbody, a transparent sealing cover plate, an oil inlet pipe, sight glass, a one-way valve and a pump. The transparent sealing cover plate is provided with a threaded hole used for mounting the oil inlet pipe and integrally arranged above the sliding bearing body; the sight glass is arranged in the oil inlet pipe; the one-way valve is arranged at the position of a bearing bush oil outlet of the sliding bearing body, and the pump is connected to the oil inlet pipe between the sight glass and the one-way valve in series. The oil pump is arranged on the outer side of the sliding bearing, lubricating oil in the sliding bearing is pumped out from the lower part of the bearing seat through the micro-backpressure one-way valve; the lubricating oil enters the space between a shaft and a bearing from the top of the sliding bearing, the transparent sight glass is arranged on a pipeline before the lubricating oil enters the bearing, observation can be conducted through observation of the sight glass, it is guaranteed that enough lubricating oil flows into the sliding bearing, formation of an oil film is facilitated, and abrasion between a bearing bush and the shaft is reduced.

Description

technical field [0001] The invention relates to a lubricating device for a self-lubricating sliding bearing, which belongs to the technical field of bearing lubricating devices. Background technique [0002] Sliding bearings are widely used for their long life, high speed, shock and vibration load and low noise. Sliding bearings are divided into self-lubricating and forced-lubricating if they are distinguished according to their lubrication methods; the sliding bearings with forced lubrication need to have lubricating oil flowing before the motor starts and during operation, so as to ensure that there is enough lubricating oil between the shaft and the motor when starting. The bearing temperature is lowered between the bearings at the same time, but this kind of lubrication method requires a separate lubricating oil station to supply oil to the bearings, which not only increases the cost of use, but also consumes a lot of electric energy. For occasions where the bearing temp...

Sliding bearings are divided into self-lubricating and forced-lubricating if they are distinguished according to their lubrication methods; the sliding bearings with forced lubrication need to have lubricating oil flowing before the motor starts and during operation, so as to ensure that there is enough lubricating oil between the shaft and the motor when starting. The bearing temperature is lowered between the bearings at the same time, but this kind of lubrication method requires a separate lubricating oil station to supply oil to the bearings, which not only increases the cost of use, but also consumes a lot of electric energy. For occasions where the bearing temperature is not high during operation, if It is possible to keep enough lubricating oil on the shaft and the sliding bearing bracket before starting, so that the lubricating oil station can no longer be used, thus saving costs and reducing the control logic in actual use

[0003] In the prior art, there is no lubricating oil between the shaft and the sliding bearing after being placed for a long time, resulting in the wear of the alloy on the surface of the sliding bearing during the starting process
