Description
Technical Field
The invention relates to a lubricating device of a self-lubricating sliding bearing, and belongs to the technical field of bearing lubricating devices.
Background
Plain bearings are widely used for their advantages of long life, suitability for high speed, resistance to shock and vibration loads and low noise. If the sliding bearings are distinguished according to the lubricating modes, the sliding bearings are divided into self-lubricating and forced lubricating; the sliding bearing of force-feed lubrication needs to have lubricating oil to flow before the motor is started and in operation all the time, in order to ensure that enough lubricating oil reduces the bearing temperature between the shaft and the bearing when starting, but this kind of lubricating mode needs to have an independent lubricating oil station to supply oil for the bearing, not only increases the use cost, but also consumes a large amount of electric energy, for the occasion that the bearing temperature is not high in the operation process, if can keep the shaft and the sliding bearing support to have enough lubricating oil to exist before starting, just can no longer use the lubricating oil station, thereby save the cost, reduced the control logic in practical use.
In the prior art, lubricating oil is not available between a shaft and a sliding bearing after the shaft and the sliding bearing are placed for a long time, so that the condition that the alloy on the surface of the sliding bearing is abraded in the starting process is caused.
Disclosure of Invention
The present invention is directed to solve the above problems of the prior art, and further to provide a lubricating device for a self-lubricating sliding bearing.
The purpose of the invention is realized by the following technical scheme:
a lubrication arrangement for a self-lubricating plain bearing comprising: the oil-feeding type sliding bearing comprises a sliding bearing body, a transparent sealing cover plate, an oil feeding pipe, a sight glass, a one-way valve and a pump, wherein a threaded hole for installing the oil feeding pipe is formed in the transparent sealing cover plate, the sight glass is installed in the oil feeding pipe, the one-way valve is installed at the position of an oil outlet of a bearing bush of the sliding bearing body, and the pump is connected in series with the oil feeding pipe between the sight glass and the one-way valve. The pump is a manual pump or an electric pump.
The invention uses the oil pump (manual pump or electric pump) outside the sliding bearing to pump the lubricant inside the sliding bearing from the lower part of the bearing seat through the one-way valve with micro back pressure, and enters between the shaft and the bearing from the top of the sliding bearing, and the pipeline before entering the bearing is provided with the transparent sight glass, which can observe through the sight glass to ensure that enough lubricant flows into the sliding bearing.
Through the process, the lubricating oil flows into the sliding bearing before the equipment is started, so that enough lubricating oil is reserved between the bearing bush and the shaft of the sliding bearing, the formation of an oil film is facilitated, and the abrasion between the bearing bush and the shaft is reduced.
In the whole process, the lubricating oil is extracted from the oil tank of the bearing seat, passes through the lubricating bearing and then returns to the oil tank of the bearing seat again, the oil level height of the sliding bearing is not changed in the whole process, and the oil level height is kept consistent all the time.
The invention has the advantages of solving the defects that the bearing bush is abraded and the service life of the sliding bearing is influenced because no lubricating oil exists between the shaft and the bearing in the starting process of the self-lubricating sliding bearing, and avoiding the oil leakage phenomenon caused by the rise of the oil level of the bearing when the device is used.
Drawings
Fig. 1 is a schematic structural view of a lubricating device of a self-lubricating sliding bearing of the present invention.
In the figure, reference numeral 1 is a sliding bearing body, 2 is a transparent sealing cover plate, 3 is an oil inlet pipe, 4 is a sight glass, 5 is a one-way valve, and 6 is a pump.
Detailed Description
The invention will be described in further detail below with reference to the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation is given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1, a lubricating device for a self-lubricating sliding bearing according to the present embodiment includes: slide bearing body 1, transparent sealing cover plate 2, advance oil pipe 3, sight glass 4, check valve 5 and pump 6, transparent sealing cover plate 2 is last to have the screw hole that is used for installing into oil pipe 3 and wholly install in slide bearing body 1's top, sight glass 4 is installed in advancing oil pipe 3, be used for looking over whether lubricating oil flows through in the oiling process, check valve 5 installs the axle bush oil-out position at slide bearing body 1, check valve 5 is owing to there is small back pressure, can effectively prevent because the external pipeline trouble makes lubricating oil run off, lead to the emergence of shut down the accident, also can prevent the foreign matter entering. The pump 6 is connected in series with the oil inlet pipe 3 between the sight glass 4 and the one-way valve 5.
The pump 6 is a manual pump or an electric pump.
The working process of the lubricating device of the self-lubricating sliding bearing of the embodiment is as follows: just before starting the motor, the pump 6 is operated to generate negative pressure between the one-way valve 5 and the pump 6, so that lubricating oil enters the inside of the bearing from the sliding bearing body 1 through the one-way valve 5, the pump 6, the sight glass 4 and the oil inlet pipe 3 and reaches the space between the sliding bearing and the shaft, and the purpose of lubrication before starting is achieved.
The above description is only a preferred embodiment of the present invention, and these embodiments are based on different implementations of the present invention, and the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
