Preferably, described bosh has water inlet, delivery port and cell body, and described water inlet and delivery port are separated setting, and it is circular-arc that cell body becomes, and water inlet is communicated with one end of cell body, and delivery port is communicated with the other end of cell body.
Preferably, described the first sealing ring, the second sealing ring, the 3rd sealing ring and cell body are all coaxial with lid.
Preferably, described counterbore is multiple, and spaced apart around the axis of lid.
Preferably, the middle part of described lid has shoulder hole, is fitted with the wear-resisting collar of a size coupling on this shoulder hole, and the upper portion side wall of this wear-resisting collar is radially protruding with annular flange flange, the step surface laminating of this annular flange flange and shoulder hole.
Preferably, the upper end of the described wear-resisting collar and the upper surface flush of lid, the lower end of the wear-resisting collar flushes with the lower surface of lid.
Compared to existing technology, the beneficial effects of the utility model are:
The utility model is by offering bosh at lid upper surface, coordinate outer loop water system, can carry out effective cooling heat radiation to lid, make the parts in shell and the shell of electric main shaft obtain good cooling effect, simultaneously, after coordinating with the shell of electric main shaft, the first sealing ring, the second sealing ring and the 3rd sealing ring have played three layers of anti-gas-leak effect, pass to compressed-air actuated situation to adapt to air-flotation electric spindle domestic demand, and, the second sealing ring and the 3rd sealing ring also play waterproof action, prevent that the water in bosh from spilling, guarantee gas, cooling water passes through smoothly in cover plate assembly, in addition, the wear-resisting collar has anti-wear effect, can effectively avoid axle core on electric main shaft and the gouging abrasion of the wear-resisting collar, and protection axle core runs well.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
