Technical field

This application involves technical field of motors, more particularly to a kind of motor transmission shaft and with its magneto.

Background technique

With the development of the social economy, industrially proposing increasingly higher demands to energy-saving consumption-reducing.Due to magneto There is superior energy-saving consumption-reducing to act on, and can be realized large torque and directly drive, does not need to save equipment peace using speed reducer Space is filled, therefore, magneto is gradually widely used.

Industrially when directly driving using magneto low speed, high speed shaft shaft coupling and speed reducer, but permanent magnetism are eliminated The output shaft of motor appoints so shaft coupling is needed to connect at present in axis connection driven with low speed, the more parts of whole set equipment, then More maintenace points, and shaft coupling belongs to wearing detail.In addition, transmission shaft (i.e. rotor axis of electric) in the prior art is generally band There is the entity axis of step, which is fixedly connected with rotor field spider, and output shaft passes through shaft coupling and driven axis connection.Due to connection The presence of axis device can also make the installation space demand of equipment larger, if used in below ground, bigger equipment is installed empty Between more will lead to being significantly increased for use cost, such as underground mining operating condition, then need to exploit bigger tunnel, to guarantee equipment foot Enough installation spaces, this will lead to construction cost and increased dramatically.

Thus, it is desirable to have a kind of technical solution overcomes or at least mitigates at least one drawbacks described above of the prior art.

Apply for content

The application's is designed to provide a kind of motor transmission shaft and overcomes or at least mitigate with its magneto At least one drawbacks described above of the prior art.

To achieve the above object, the application provides a kind of motor transmission shaft, and the motor transmission shaft includes:

Ring gear, the ring gear are provided with internal tooth；

Central axis, one end of the central axis are provided with the external tooth with internal tooth cooperation, the other end of the central axis It is provided with axle sleeve；Part between the axle sleeve and the external tooth is the ontology of the central axis.

Optionally, be provided with rolling bearing or bearing shell between the ring gear and the central axis, the rolling bearing or Bearing shell is used to support the central axis and ring gear.

Optionally, the axial ends of the ring gear is provided with sealing cover, and the central axis passes through one of sealing cover, And the internal tooth of the ring gear and the external tooth mating part of central axis are located between two sealing covers.

Optionally, the axle sleeve of described central axis one end is any one in hydraulic controlled sleeve, hub splines or thick-walled sleeve.
