Embodiment 1

[0025] see Figure 1-6 , the present invention provides the following technical solutions: a thrust bearing for a submersible submersible motor, comprising an end cover 1, an oil chamber 2 is formed in a ring on the end cover 1, lubricating oil is housed in the oil chamber 2, and the top side of the oil chamber 2 A through hole 3 is opened on the inner wall, and a water floating shaft 4 is installed in the oil chamber 2. The top of the water floating shaft 4 penetrates the through hole 3 and extends to the outside of the through hole 3. During the use of the water pump, there is water pressure under water. The water pressure causes the pressure of the part of the first cavity 7 close to the air inlet 9 to increase, causing the first piston 8 to move closer to the end cover 1, so that the part of the first cavity 7 close to the end cover 1 is lubricated. The oil flows into the oil chamber 2, the lubricating oil pressure in the oil chamber 2 increases, and the lubricating oil en...

Abstract

The invention belongs to the technical field of bearings, and particularly relates to a thrust bearing for a submersible and oil-submerged motor. The thrust bearing comprises an end cover, wherein anoil cavity is annularly formed in the end cover, lubricating oil is contained in the oil cavity, a through hole is formed in the inner wall of the top side of the oil cavity, a water floating shaft isinstalled in the oil cavity, the top end of the water floating shaft penetrates through the through hole and extends out of the through hole, a sealing ring is fixedly connected to the water floatingshaft in a sleeve mode, the sealing ring is in sealed connection with the through hole, one side of the end cover is fixedly provided with a first fixing seat, and a first cavity is formed in the first fixing seat. According to the thrust bearing, the design that the liquid water floating shaft is used for replacing a conventional bearing with the service life limited by rolling friction and thestatic lubricating oil is adopted, when a water pump is subjected to water pressure underwater, the lubricating oil can automatically flow, when the working depth of the water pump is very small, andthe pressure difference is very small, a micro water pump is started so as to realize external oil supply, the lubricating oil in the oil cavity is made to flow, the lubricating oil keeps flowing, thepart loss is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of thrust bearings, and in particular relates to a thrust bearing for a submersible submersible motor. Background technique [0002] The submersible submersible motor is a motor that can work underwater or under oil. During the working process of the motor, the submersible pump will give a reaction force to the motor shaft. The self-adjusting thrust bearing can bear the axial force of the motor shaft and ensure Its axial movement is within an acceptable range. When the motor is subjected to a large axial load, a thrust bearing is used to bear the axial force of the bearing. The structure of the thrust bearing belongs to the conventional bearing design of rolling friction and static oil lubrication life. There is mechanical loss, and the bearing life is limited to the wear of lubricating grease and rollers. There is loss, and a new type of thrust bearing is urgently needed. Contents of the invention [00...
