Description
Technical field
The present invention relates to variable-frequency adjustable-speed asynchronous traction motor, be specially a kind of large tractor alternating current electric drive system
Use traction motor.
Background technology
The trend of big-power tractor is to use alternating current drive system to replace Hydraulic Power Transmission System the most in the world, and passes
The traction motor of system cannot meet the mounting condition of large tractor, the kind of drive and the type of cooling.
Summary of the invention
The present invention is to solve that existing traction motor exists and cannot meet the mounting condition of large tractor, the kind of drive
And the problem of the type of cooling, it is provided that a kind of large tractor alternating current electric drive system traction motor.
The present invention adopts the following technical scheme that realization: the traction of large tractor alternating current electric drive system is electronic
Machine, including support, the left and right sides of support is provided with middle indentation type drive end bearing bracket and rear end cap, sets between drive end bearing bracket and rear end cap
It is equipped with hollow internal spline rotating shaft, and the left and right sides of hollow internal spline rotating shaft is provided with 6222-2Z bearing；Support outer wall is arranged
There is annular water channel, annular water channel has some spray apertures, be provided with double-deck O type between support and drive end bearing bracket and rear end cap close
Seal；It is provided with rotor punching on hollow internal spline rotating shaft, outside rotor punching, is cased with stator punching, hollow on front side of rotor punching
It is provided with fan on internal spline rotating shaft, drive end bearing bracket, rotor punching, rear end cap are provided with air vent；Arrange on stator punching
Have by the stator winding of Inverter fed motor enamel-covered wire coiling, and stator winding end is provided with PT100 pyrostat.
The horizontal installation of this motor, and its drive end bearing bracket and rear end cap use concave shaped structure, reduces two bearings support interval,
Reducing rotating shaft deflection, reduce vibration and the noise of motor, during motor work simultaneously, cooling water sprays and mistake from annular water channel, band
Walk stator heat, overcome existing traction motor and exist and cannot meet the mounting condition of large tractor, the kind of drive and cold
But the problem of mode.
Present configuration is reasonable in design reliably, meets the installation requirement of large tractor, and reduces shaking of motor
Dynamic and noise, extends service life, it is ensured that globality and reliability, has simple in construction, easy to operate and low cost
Advantage.
