Bearing and deep-well pump transmission shaft system provided with bearing

Abstract

The invention discloses a bearing and a deep-well pump transmission shaft system provided with the bearing, and belongs to the technical field of bearing machines. The bearing comprises an outer shaft sleeve and an inner shaft sleeve, wherein the outer shaft sleeve is arranged on the outer side of the inner shaft sleeve; a plurality of spaced oil seeping annular grooves are axially formed in the outer peripheral wall of the outer shaft sleeve; clamping annular grooves used for connecting the outer shaft sleeve to the inner shaft sleeve are formed in the inner peripheral wall of the outer shaft sleeve; clamping convex blocks matched with the clamping annular grooves are arranged on the outer peripheral wall of the inner shaft sleeve; the outer shaft sleeve is used to be matched with an outer shaft pipe of the transmission shaft system; the inner shaft sleeve is used to be matched with a long shaft of the transmission shaft system; a first plug-in mounting oblique surface is arranged in a position of one end, corresponding to the outer peripheral wall of the outer shaft sleeve, of the outer shaft sleeve; second plug-in mounting oblique surfaces are arranged in he positions of the two ends, corresponding to the inner peripheral wall of the inner shaft sleeve, of the inner shaft sleeve; and oil seeping notches are formed in the positions of the two ends, corresponding to the end faces of the outer shaft sleeve, of the outer shaft sleeve. The bearing and the deep-well pump transmission shaft system can effectively exert a vibration reduction function; a high temperature situation caused by insufficient lubrication of the transmission shaft system is avoided; and the safety performance is improved accordingly.

Description

technical field [0001] The invention belongs to the technical field of bearing machinery, in particular to a bearing and a deep well pump transmission shaft system with the bearing. Background technique [0002] A deep well pump is a device used to pump liquid cargo from the liquid cargo tank to the outside of the liquid cargo tank. A common deep well pump usually includes a pump body placed in the cargo tank, a motor placed outside the cargo tank, and a drive shaft set between the pump body and the motor. The drive shaft is used to transmit the power output by the motor to the pump. The transmission shaft system includes a major shaft and an outer shaft tube sleeved outside the major shaft, and a bearing is arranged between the outer shaft tube and the major shaft. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] Since the liquid cargo tank is usually loaded with flamma...
