Axle head broach snap ring assembly structure

The utility model provides a development trend is to the development of maximizing that axle head broach snap ring assembly structure, the problem that solve is current BCL type centrifugal compressor to satisfy the demand that the user's set maximized. The maximization of unit leads to the sealed outside diameter with end cover cooperation department of axle head big, and the sealed size of axle head is thick, if use the axle head seal structure of conventional form, certainly will lead to the fact axle head obturator size great, require to add lock nut and spacer excircle size on the greater trochanter simultaneously, the processing sealed for the axle head brings more difficulty with the assembly, is difficult to guarantee machining precision and assembly precision to increased the rotor weight, the steady running of antitrochanter is unfavorable, the utility model provides a cross -section of broach sealing member has fixed tooth for type shape, its bottom, and one side shoulder agrees with with the pump
