The disadvantages are heavy weight, poor thermal conductivity, inability to die cast, poor plasticity, and lower elongation than aluminum.
The motor can generate heat energy during operation, releases heat, has poor heat conduction and heat dissipation, often causes the temperature in the motor to be too high, thereby causing alarm emergency stop, and simultaneously, due to the principle of thermal expansion and cold contraction, parts in the cast iron motor, such as a drive motor shaft and some rotating parts on the upper part of the drive motor shaft, are tighter in contact surface adhesion of the parts due to thermal expansion, and the friction force generated during operation is larger, so that the abrasion loss is also increased.
[ utility model ]
The utility model aims to provide a cast iron motor to solve the problems that the existing motor generates heat energy in operation and has poor heat conduction and heat dissipation, and alarming scram is easy to cause; meanwhile, due to the principle of thermal expansion and cold contraction, the friction force generated by parts in the motor during operation is increased, and the abrasion loss can be increased along with the increase.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the cast iron motor comprises a motor shell and a drive motor shaft, wherein the drive motor shaft is arranged in the motor shell, a cooling water channel is arranged in the motor shell, and a water outlet and a water inlet are respectively arranged at two ends of the cooling water channel; and an oil hole is formed in the motor shaft of the drive motor.
Further, the cooling water channel is in a spiral shape, and a bending part is arranged on the cooling water channel.
Further, a process hole is formed in the motor shell, and the process hole is communicated with the cooling water channel.
Further, the cross section of the cooling water channel is rectangular.
Further, the wall thickness of the cooling water channel and the inner cavity of the motor shell is 3-5mm.
Further, the axis of the drive motor shaft is in a through hole shape, an annular groove and a shoulder are formed in the right side face of the drive motor shaft, and the oil hole is formed in the annular groove and the shoulder.
The beneficial effects achieved by the utility model are as follows:
the multi-ring spiral cooling water channel is arranged in the motor shell, corresponding bending is designed on the cooling water channel, the length of the cooling water channel can be prolonged, the contact area with the motor shell is increased, each ring of the spiral cooling water channel can be guaranteed to be on the same plane by arranging the bending, and the cooling flow channel is relatively reasonable in arrangement; in addition, the inside of the cast iron motor is improved to enable the motor shaft to throw out engine oil inside the motor shaft through centrifugal force in the rotating process, so that corresponding rotating parts are lubricated, the abrasion loss is reduced, and the service life of the motor is prolonged.
