An oil scraping device based on a sliding bearing oil supply system

Abstract

The invention relates to an oil-scraping device based on a sliding bearing oil supply system. With the adoption of the technical scheme that the device comprises an oil scraper, a rotary shaft, an oil disc, oil sealing hoods, a speed measuring unit, a controller and an executing unit, wherein the oil disc sleeves the surface of excircle of the rotary shaft and is fixedly connected to the rotary shaft; the two oil sealing hoods are symmetrically distributed on two sides of the oil scraper in the periphery of the oil disc, and the oil scraper is arranged in an T-shape and is assembled with the oil disc; the executing unit is arranged on the oil scraper, is fixed on an oil supply system body and is connected to the rotary shaft through the controller and the speed measuring unit to adjust the gap between the oil scraper and the oil disc, defects that the application range is limited when the operation is unsmooth, the bearing leaks oil and the rotating speed is too low as the circular flow is too large for a long time in an existing self-lubricating sliding bearing oil disc are overcome, and the problems that the output oil quantity of the oil supply system cannot be controlled, the operation efficiency of equipment is low, and the environmental pollution is easily caused as a result of leakage can be solved. The device can be widely applied to self-lubricating matched use of various sliding bearings.

Description

technical field [0001] The invention relates to an oil scraping device based on a sliding bearing oil supply system. Background technique [0002] The existing self-lubricating sliding bearings generally adopt the oil supply structure of the oil pan. The oil pan and the shaft are rigidly connected and rotate synchronously; Keep a certain gap. When the oil pan rotates, due to the pumping effect, the oil pan can bring the lubricating oil from the liquid surface through the gap into the corresponding oil inlets on both sides of the oil scraper, and from the oil outlet of the oil scraper. flow to the bearing bush for lubrication; however, since the gap between the oil scraper and the oil pan cannot be adjusted, in practical applications, the amount of oil scraped and output by the oil scraper is affected by the rotation speed of the rotating shaft and cannot be controlled; when the gap At a certain time, if the shaft speed is low, the oil output through the oil scraper is too s...

[0002] The existing self-lubricating sliding bearings generally adopt the oil supply structure of the oil pan. The oil pan and the shaft are rigidly connected and rotate synchronously; Keep a certain gap. When the oil pan rotates, due to the pumping effect, the oil pan can bring the lubricating oil from the liquid surface through the gap into the corresponding oil inlets on both sides of the oil scraper, and from the oil outlet of the oil scraper. flow to the bearing bush for lubrication; however, since the gap between the oil scraper and the oil pan cannot be adjusted, in practical applications, the amount of oil scraped and output by the oil scraper is affected by the rotation speed of the rotating shaft and cannot be controlled; when the gap At a certain time, if the shaft speed is low, the oil output through the oil scraper is too small, and sometimes it cannot meet the oil demand for bearing lubrication at all; if the shaft speed is high, the oil output through the oil scraper is too large, and the oil Excessive circulating flow rate will lead to poor operation, especially to the sealing of the bearing. In severe cases, it will cause oil leakage from the bearing and cause pollution. Moreover, the application range is limited due to the control of too high or too low speed. low efficiency
