Mounting structure of synchronous motor oil cooling machine base with rear sealing cover plate

Technical Field

The utility model relates to a synchronous machine's field, concretely relates to take mounting structure of back seal cover plate synchronous machine oil cooling frame.

Background

The invention of the motor made it one of the active driving forces after the industrial revolution more than a century ago. Its widespread use in various mechanical sports has made life simple and ultimately has driven human progress. People also continuously pursue the improvement of the performance of the motor and the optimization of the production process, and the oil-cooled motor gradually occupies more market demands by higher mechanical efficiency, better heat dissipation performance and better observability compared with the air-cooled motor, but the mould opening is difficult and the manufacturing cost is high due to the hollow inside of the shell of the oil-cooled motor, so that the oil-cooled heat dissipation is a non-preferred heat dissipation mode.

The problems of the structural form and the processing technology of the oil cooling machine base circulating in the current market are as follows:

1. the base is integrally opened, and the inner part of the base is hollow, so that the opening of the base is difficult, the thickness of the mould is uneven, poor pouring is easy to occur, fracture, sand holes and the like are formed, and the yield of finished products is great;

2. the hollow part of the engine base processed by the traditional mode can not be subjected to rust prevention treatment, rust spots are easy to appear after the engine base is placed for a long time, impurities are generated, the efficiency and the service life of oil cooling circulation are reduced, and meanwhile, the risk of poor sealing is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a take mounting structure of back seal cover board synchronous machine oil cooling frame.

The purpose of the utility model is accomplished through following technical scheme: the mounting structure of the synchronous motor oil cooling machine base with the rear sealing cover plate mainly comprises a machine base, the rear sealing cover plate and a rear end cover, wherein sealant is uniformly smeared on a connecting end face A of the machine base and the rear sealing cover plate, a plurality of blind holes and counter bores are formed in a connecting end face B of the rear sealing cover plate and the rear end cover plate, screw holes are formed in positions, corresponding to the counter bores, of the machine base, the counter bores and the screw holes are connected through inner hexagonal cylindrical head screws, the machine base and the rear sealing cover plate are fastened and fixed, through holes are formed in positions, corresponding to the blind holes, of the rear end cover plate, the through holes and the blind holes are connected through the inner hexagonal cylindrical head screws with spring washers, and the rear sealing.

Furthermore, a step surface A is arranged on the connecting end surface A, a step surface B is arranged on the connecting end surface B, and the step surface A and the step surface B are coaxial.

Further, the blind holes and the counter bores are uniformly distributed along the circumference of the connecting end face B.

Furthermore, a rectangular groove is arranged between any adjacent blind hole and the counter bore.

The utility model has the advantages that: the oil-cooled motor base is divided into a rear sealing cover plate and a base main body, and the mould opening is respectively carried out, so that the mould opening difficulty is reduced, and the probability of fracture and sand holes is reduced; the internal hollow structure can be subjected to rust prevention treatment, so that the phenomenon of internal corrosion caused by long-time placement of the motor is avoided, and the motor can be used for oil cooling and water cooling in general when necessary; when the engine base leaks oil, the rear sealing cover plate or the engine base can be independently replaced or repaired, and the repairing of the motor engine base can be simplified.
