Technical Field
The utility model belongs to the technical field of bearing cooling, and particularly relates to a negative pressure oil circulating lubrication cooling bearing device.
Background
The bearing is generally installed in the bearing frame, and in the equipment operation process, the axle carries out sliding friction with the bearing, and the friction can produce the heat, and long-time operation will lead to higher heat, makes the bearing heat up, and lubricating oil is rotten, and then influences the normal operating of bearing. In the prior art, two modes of adding lubricating oil into a bearing sleeve or performing water circulation cooling in a bearing base are usually adopted to reduce the generation of heat, but the former has limited cooling effect, and the latter easily causes the corrosion of accessories and influences the service life of the bearing.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a negative pressure oil circulation lubrication cooling bearing device which is reasonable in structural design, good in cooling effect on bearing operation, obvious in lubricating effect and free of oil leakage due to negative pressure circulation.
The specific technical scheme is as follows:
the bearing block mechanism comprises a bearing sleeve, a bearing and an operation shaft, wherein the bearing and the operation shaft are arranged in the bearing sleeve, and an oil outlet and an oil inlet are formed in two ends of the bearing sleeve. The oil circuit negative pressure circulating mechanism comprises a frame, an oil tank and a diaphragm pump, wherein the oil tank is provided with an oil tank oil filling port filter, an oil tank oil outlet filter and an oil tank oil inlet; the diaphragm pump is provided with an oil inlet and an oil outlet. The oil outlet of the oil tank is connected with the negative pressure oil inlet of the bearing sleeve, the negative pressure oil outlet of the bearing sleeve is connected with the oil inlet of the diaphragm pump, and the oil outlet of the diaphragm pump is in butt joint with the oil inlet of the oil tank, so that oil circuit negative pressure circulation is formed in the bearing sleeve, and on one hand, the oil tank plays a role in lubricating a running bearing and reduces friction heat production; on the other hand, the oil is cooled in the oil tank and the circulating pipeline and then continuously contacts with the bearing to absorb the heat of the bearing and reduce the temperature of the bearing.
Furthermore, the size of the operation shaft and the bearing is designed, and the size of the bearing sleeve is selected, so that the bearing sleeve is suitable for various bearings which are easy to generate heat.
Furthermore, an oil tank oil filling port filter and an oil tank oil outlet filter are arranged on the oil tank, so that the cleanness of cooling oil passing through the bearing sleeve is ensured, the bearing is cooled and lubricated, and no slag enters the bearing sleeve to form friction blockage.
Furthermore, the design adopts the negative pressure circulation of the diaphragm pump, the whole system is internally provided with negative pressure, and oil leakage is avoided.
According to the negative-pressure circulating oil cooling bearing, the bearing is lubricated by circulating the oil way of the bearing sleeve, the heat generated by the bearing is reduced, the heat generated by the bearing is absorbed by heat transfer, the bearing is always in a cooling and lubricating state, the friction damage of the bearing is reduced, the continuous running and use time of the bearing is prolonged, the service life of the bearing is prolonged, the failure rate of equipment is reduced, and the production efficiency is improved. The applicability is wider.
