Detailed Description
In order to more fully explain the practice of the utility model, examples of the practice of the utility model are provided. These examples are merely illustrative of the present utility model and do not limit the scope of the utility model.
The utility model will be explained in further detail with reference to the accompanying drawings, in which: 1: a main shaft; 2: an outer water jacket; 3: a front bearing seat; 4: a rear cover; 5: a waterproof cover; 6: a drain hole; 7: a stator; 8: a rotor; 9: a housing; 10: a rear bearing seat; 11: a front bearing; 12: a rear bearing; 13: a seal ring; 14: pressing the cap; 15: a front nut; 16: an annular groove; 17: and (5) sealing the framework.
The front bearing seat in the utility model can also be called a front large cover, a front gland and the like.
As shown in the drawing, the electric spindle for diamond machining comprises a stator 7 and a rotor 8, wherein the spindle 1 and the rotor are fixedly integrated, a shell 9 is arranged outside the stator, a water channel is arranged on the periphery of the shell, cooling water is communicated with the water channel, an outer water jacket 2 is sleeved outside the shell 9, a front bearing seat 3 is fixedly connected with the front part of the shell 9, a rear bearing seat 10 is arranged behind the shell, a rear cover 4 is fixedly connected onto the shell behind the rear bearing seat, two ends of the spindle are respectively supported in a front shaft, 11 and 12, the front bearing 11 is arranged in the front bearing seat 3, the rear bearing 12 is arranged in the rear bearing seat 10, a sealing ring 13 is arranged at the front end of the front bearing, a press cap 14 is arranged at the front part of the sealing ring, and the press cap is screwed in the front bearing seat through threads.
