The specific embodiment
The utility model is shown in Fig. 1-4: comprise traction sheave 1, brake equipment 7, restraining coil 6, rotor 5, stator case 4 and front shroud 2, described stator case 4 is oblate tubbiness, the back shroud 40 of described bucket end double as stator case 4; Described front shroud 2 is respectively equipped with front bearing hole and the rear bearing hole that is connected rotor 5 with back shroud 40, is fixedly connected with the inner water sleeve 3 of annular on the inner barrel wall face of stator case 4.
The top of described front shroud 2 is provided with water inlet 8, the bottom is provided with water outlet 10, and described water inlet 8 and water outlet 10 are communicated with described inner water sleeve 3.
Be provided with radially water channel 41 of back shroud in the described back shroud 40; Described back shroud radially water channel 41 connects described inner water sleeve 3.
Outside, rear bearing hole is provided with a circle rear bearing hole Coolant gallery 9 on the described back shroud 40, and described rear bearing hole Coolant gallery 9 is communicated with radially water channel 41 of described back shroud.
The utility model can be external a complete constant low-temperature water source water cooling of cover or the constant temperature system of heating.
The utility model can also be provided with temperature measuring equipment on the towing machine housing, when being higher than required best coolant water temperature, system sends signal to cooling water, starts the cooling circulation water supply system, and cooling water expansion tank is remained in the best cooling range.
