Abstract

The invention relates to the field of submersible linear motors, in particular to a submersible linear motor and a rotor thereof. The rotor of the submersible linear motor comprises a rotor inner pipe, wear-resistant magnetic conduction rings and magnets, wherein the wear-resistant magnetic conduction rings and the magnets are arranged on the rotor inner pipe at intervals. The rotor inner pipe is of a hollow structure. Oil passing passageways are arranged on the pipe wall. Oil guide grooves are formed in the end faces of the wear-resistant magnetic conduction rings. The oil passing passageways and the oil guide grooves are communicated with each other. The oil passing passageways and the oil guide grooves are communicated with each other, and therefore a circulation lubricating oil way is formed by the oil passing passageways, the oil guide grooves and a stator inner cavity. When the submersible linear motor rotor reciprocates to work, the pressure difference is generated by the two ends of the submersible linear motor stator inner cavity, and lubricating oil can pass through the oil passing passageways of the rotor inner pipe, flows through the oil guide grooves in the end faces of the wear-resistant magnetic conduction rings and flows to the friction faces of the wear-resistant magnetic conduction rings and the stator inner cavity to form a protection oil film. By forming the protection oil film, friction between the wear-resistant magnetic conduction rings and the stator inner cavity can be effectively relieved, and therefore the service life of the submersible linear motor is easily prolonged.

Description

technical field [0001] The invention relates to the field of oil submersible linear motors, in particular to an oil submersible linear motor and a mover thereof. Background technique [0002] The stator and the mover of the submersible linear motor are in a clearance fit. Due to the existence of magnetic attraction, the mover and the stator are always in a non-concentric state. When the inner cavity of the stator is filled with lubricating oil, due to the eccentricity of the mover, the lubricating oil on the friction surface will always be pressed out. The wear of the motor stator and mover affects the service life of the submersible linear motor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil submersible linear motor and a mover in view of the above-mentioned defects of the prior art, which overcomes that the lubricating oil on the friction surface cannot be replenished during the movement of the mover ...
