Thrust bearing and lubricating device thereof

Abstract

The invention provides a thrust bearing and a lubricating device thereof. The thrust bearing comprises a shaft washer, a housing washer and a rolling body between the shaft washer and the housing washer, and is characterized in that an oil pumping device is arranged on the outer side of the shaft washer. The lubricating device of the thrust bearing comprises a shaft, a radial bearing and a bearing pedestal, and is characterized in that the bearing pedestal is provided with an oil inlet in one side of the bearing and is provided with an oil outlet in the other side of the bearing; the oil inlet and the oil outlet are respectively connected with an oil tube; one end of an oil inlet tube is connected with a cooling device, one end of an oil outlet tube is connected with a magnetic filter, and the cooling device is communicated with the magnetic filter. Therefore, lubricating oil can be continuously supplied to the bearing through the oil pumping device, the temperature of the lubricating oil can be controlled within a certain range through the cooling device, and the lubricating oil passing through a coiled pipe in a water tank is filtered through the magnetic filter, is cooled and then returns inside the bearing pedestal, so that the high temperature of the bearing rotating at high speed can be effectively reduced, the lubricating oil is cleaned through the magnetic filler, the friction force of the bearing is reduced, and the service life of the bearing is prolonged.

Description

[0001] technical field [0002] The invention relates to a thrust bearing and a lubricating device for the bearing. Background technique [0003] The bearing is assembled on the shaft, and the bearing is concentric with the shaft and rotates around the concentric shaft. During use, the bearing will generate a certain amount of friction, which will cause wear to the bearing and affect the service life of the bearing. The traditional method is that during the assembly process, in the Apply lubricating grease on the bearing. The lubricating grease is a paste-like grease that lubricates the bearing. However, the heat dissipation effect of the lubricating grease is not ideal. With the use of the equipment, the lubricating grease will continue to volatilize and dry out. Re-apply grease on the mating surface, and apply grease again, only to disassemble the assembled bearing, which causes a lot of inconvenience and reduces production efficiency. At the same time, the bearing unde...

Problems solved by technology

[0003]The bearing is assembled on the shaft. The bearing is concentric with the shaft and rotates around the concentric shaft. During use, the bearing will generate a certain amount of friction, which will cause wear to the bearing and affect the For the service life of the bearing, the traditional method is to apply grease on the bearing during the assembly process. The grease is a paste-like grease that lubricates the bearing. With the use of equipment, the grease will continue to volatilize and dry out, and it is necessary to reapply grease on the mating surface, and to reapply grease, only the assembled bearings must be disassembled, which causes a lot of inconvenience and reduces production efficiency. The bearing under high-speed rotation tends to heat up and heat up, which greatly increases the friction force. There is a lubricating device for the bearing, such as the patent No. 200910171398.4. At least one side of the bearing along the axial direction is provided with an oil suction device. The oil suction device is a worm gear device. , the bearing seat is provided with an oil inlet hole and an oil outlet hole on the side of the shaft where the oil suction device is installed and on the opposite side. The oil inlet hole and the oil outlet hole are respectively connected to the oil tank through the oil pipe. Continuous oil supply lubricates, reduces friction, and can also dissipate heat and cool down. However, this device dissipates heat through the oil tank. The higher the bearing speed, the faster the oil flow rate, and the oil temperature in the oil tank will also rise. Therefore, the temperature of the lubricating oil must be increased. It is not guaranteed, and some equipment needs to use radial bearings and plane thrust ball bearings at the same time, but the existing plane thrust ball bearings cannot be continuously lubricated and dissipated by this lubricating device
