Socket part, the side wall of the cavity be with the matched cylindrical surface of interconnecting piece, and the outer peripheral surface of interconnecting piece and the side wall of cavity are affixed
It leans on, the connecting hole is in a strip shape and the length of the connecting hole is along the axially extending of shaft, and the main shaft of head protrudes into cavity and inserts
In connecting hole, and main shaft is connected with shaft by spline, and the interconnecting piece is set in outside main shaft；The side wall of the cavity
Offer heat release hole along extending radially through for shaft, and heat release hole have it is multiple.
In above-mentioned helical-lobe compressor in the connection structure of motor and head, the spindle jacket of the head sets and consolidates
Surely there is cooling wind blade annular in shape.Cooling wind blade is rotated together with main shaft, can further speed up the radiating rate of junction.
In above-mentioned helical-lobe compressor in the connection structure of motor and head, the casing, which is arranged and is fixed with outside, is in
The diameter of the ring body of taper, ring body is gradually become smaller from motor to heading, and all heat release holes are interior with ring body
Chamber face.Ring body is entered in heat release hole and is blocked with impurity such as blocks dusts, make entirely to radiate for blocking heat release hole
The smooth progress of process is realized so that the purpose for improving transmission accuracy and job stability be made to stablize.
In above-mentioned helical-lobe compressor in the connection structure of motor and head, the one end of the ring body far from head is logical
The mode and casing for crossing tight fit are fixedly connected with.
Compared with prior art, the connection structure of motor and head has the advantage that in this helical-lobe compressor
1, head spindle extend into casing and is connected by spline with machine shaft, both effectively shortens connection knot in this way
The length of structure also ensures that shaft and main shaft remain higher concentricity, to effectively improve the precision of transmission process and steady
It is qualitative.
2, under the action of heat release hole, to accelerate the radiating rate of main shaft and shaft junction, with prevent connection structure by
There is deformation in high temperature influence, to further increase the precision and job stability of transmission.
3, under the cooperation of the side wall of cavity and interconnecting piece outer peripheral surface, main shaft is inserted into shaft and plays preferable guiding work
With to facilitate the assembling of connection structure.
4, ring body is entered in heat release hole and is blocked with impurity such as blocks dusts, made entire for blocking heat release hole
The smooth progress of radiation processes is realized so that the purpose for improving transmission accuracy and job stability be made to stablize.
