As a kind of preferred version of the present utility model, also be provided with capillary groove in the front end end of described main shaft, this capillary groove and described labyrinth circle link along the outward extending end of main-axis end, and its slot part stretches into described main-axis end.
As a kind of preferred version of the present utility model, described before the bearing of supporting arrangement be two to be the angular contact bearing that is arranged in juxtaposition, be connected with the spacer ring of arranging around described main shaft in the centre of described two angular contact bearings.
As a kind of preferred version of the present utility model, described spacer ring is cone spacer and preceding outer ring spacer before described main shaft from the close-by examples to those far off is followed successively by.
As a kind of preferred version of the present utility model, described before the bearing of supporting arrangement be three to be the angular contact bearing that is arranged in juxtaposition.
As a kind of preferred version of the present utility model, the bearing of described back supporting arrangement is two to be the angular contact bearing that is arranged in juxtaposition, and is connected with the spacer ring of arranging around described main shaft in the centre of described two angular contact bearings.
As a kind of preferred version of the present utility model, described spacer ring from the close-by examples to those far off is followed successively by back cone spacer and back outer ring spacer around described main shaft.
Technique effect of the present utility model is that described main spindle box adopts cylindric enclosed construction, and bearing supporting step is left in its inside, thereby guaranteed the rigidity of main spindle box, also avoided shaft distortion, the rigidity of main shaft itself is increased, bearing capacity increases, and bearing life improves.
Technique effect of the present utility model is that again described main shaft adopts the labyrinth circle of shaft end seal to be connected to an integral body with main shaft, and makes the thickening of front-end of spindle adpting flange, and the degree of depth of connecting bolt is guaranteed, and has guaranteed the sealing of spindle end.
Technique effect of the present utility model is again, has capillary groove at front-end of spindle, thereby has avoided main shaft that abnormal noise is arranged in operation process, has guaranteed the sealing of spindle end.
Technique effect of the present utility model is that again preceding supporting arrangement adopts two angular contact ball bearings to add middle preceding inside and outside spacer ring or three bearings constitute, and makes it increase bearing capacity.
