the repetition of the process realizes that the rubber layers 33 on the surfaces of the two groups of metal plates 32 are continuously rubbed with each other, so that heat is generated, and the solid oil body of the lubricating oil box 13 is heated to promote melting;
at the same time, the poking column 17 on the pressing rod 18 acts on the curve groove 14 to enable the lubricating oil box 13 to rotate under the force, so that the oil in the lubricating oil box 13 can be heated uniformly, and the melting of the solid lubricating oil is further accelerated; ensuring the normal operation of the motor bearing 11.
The invention has the advantages that the preheating structure is formed by arranging two groups of metal plates which are rubbed with each other, so that the problem that the viscosity of lubricating grease is increased or the static resistance moment of a motor bearing is increased due to solidification and freezing at low temperature can be solved in time when the motor encounters extreme cold weather, and the normal operation of the motor under a variable environment can be well ensured.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
