Description
Technical field
The utility model relates to technical field of motors, especially a kind of coal-winning machine water-cooled machine.
Background technology
The technology trends of low seam electric traction coal mining machine flame-proof motor adds high-power and power density, along with the continuous lifting of coal-winning machine design of electrical motor capacity, the unit volume loss produced when motor is run increases, motor each several part temperature is caused to raise, therefore limiting motor temperature rise, resolve heating and the cooling problem of motor, become one of developing subject matter of coal mining motor technology.
Coal-winning machine power of motor density is high, unilateral magnetic force is large, specific diameter is than large, for ensureing that the strength and stiffness of rotor axis of electric and support meet the demands, need the structure improving existing coal-winning machine motor, again due to coal-winning machine machine operation bad environments, the coal-winning machine motor demand fulfillment field service requirement easily of improvement.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, and provide a kind of strength and stiffness requirement meeting rotor axis of electric and support, field service is coal-winning machine water-cooled machine easily.
The utility model solves the technical scheme that its technical problem adopts: a kind of coal-winning machine water-cooled machine, this motor comprises front end housing, rear pressing cover, support, output shaft and terminal box, also comprise rotor hollow shaft, described rotor hollow shaft is supported by bearing, front end housing and rear pressing cover, rotor hollow shaft is connected by spline pair near end with output shaft, and front end place is provided with external splines.
Further, described rear pressing cover is provided with handle, and described handle is connected to rear pressing cover by pin.Extract pin when changeing, lay down rear pressing cover, available handle directly pulls out output shaft, is convenient to safeguard and change.
Further, the upper end of described motor has water inlet, and the bottom of described support is provided with delivery port.Water inlet and delivery port coexist non-shaft stretching end, are beneficial to waterway circulating, easy to use.
The beneficial effects of the utility model are: this motor meets the strength and stiffness requirement of rotor axis of electric and support, and field service is convenient.
