Description

System integrated type direct drive motor

Technical Field

The utility model relates to a motor and supporting mechanical equipment technical field, concretely relates to system integrated form direct drive motor.

Background

When the motor is manufactured, the motor is generally manufactured separately into an independent motor, and then is connected with other equipment to be driven through transmission parts such as a coupler/belt pulley/speed change gear/chain and the like, and the transmission parts have energy loss, so that the overall efficiency of the equipment system is reduced, and the energy consumption is increased. And because the individual motor bearing and equipment transmission part also need to be maintained and replaced after the life-span expires, increased the maintenance cost and lead to the production benefit loss when equipment shut down.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a system integrated form direct drive motor, including equipment casing and equipment pivot, the one end of equipment pivot extends to the equipment casing outside, and motor rotor is installed to the both sides of equipment pivot lateral surface, and the outside of rotor is provided with motor stator, and motor stator's the outside is fixed with the connection shell, and the connection shell passes through bolt A to be connected with the equipment casing.

Furthermore, a cover plate is arranged on one side of the end part of the motor stator and is connected with the connecting shell through a bolt B.

Furthermore, the rotating shaft of the equipment is fixed with the rotor of the motor in an interference fit fixing mode.

Furthermore, the rotating shaft of the device is fixed with the rotor of the motor in a thread locking mode.

Furthermore, the torque transmission between the rotating shaft of the equipment and the rotor of the motor adopts an interference fit mode.

The utility model discloses beneficial effect as follows:

the system integrated direct drive motor has the advantages that the traditional external independent motor, a transmission mechanism and a motor installation mechanism are omitted, the equipment volume is obviously reduced, the maintenance items, the cost and the time of the equipment are reduced, the system drive efficiency is greatly improved, and the system integrated direct drive motor has obvious advantages in the aspects of energy conservation, consumption reduction and equipment benefit improvement.
