It is pressed with the right press fitting end of " Z " font link block on right bent axle outside the circle of position, is set on the big cylindrical surface at right bent axle and right press fitting end
There is positioning key, finally fixed in the outside at right press fitting end by gasket and screw；
Bearing connects again with the piston rod of air compressor machine, forms the driving of air compressor machine.
Further improvement lies in that：Left clump weight, the right side of corresponding right axle shaft are additionally provided on the outside of the left bent axle of the left half axle
Right clump weight is equipped on the outside of bent axle.
Further improvement lies in that：Input end of motor, left bent axle and left clump weight in the left half axle are cast for nodular cast iron
The integral structure made；Right connecting pin, right bent axle and right clump weight in right axle shaft are the integral structure of nodular cast iron casting；
" Z " font link block casts for nodular cast iron.
Further improvement lies in that：The left bent axle and right bent axle are pressed " Z " font link block using heat pressing process.
Further improvement lies in that：The screw thread of the screw is the anti-down rotatable structure of two-part.
Advantageous effect：
Air compressor crank of the present invention uses split structure, realizes axle bearing assembling, semi-axis structure is detachable, due to using axis
It holds and is connected with piston rod, can effectively reduce the frictional force of bent axle and connecting rod, increase the service life of bent axle；Due to using split
Formula bent axle, bent axle are oil free type structure, and bearing is connected with piston rod using bearing, and removing conventional crankshafts from needs maintaining
The problem of bearing shell.
Simultaneously because the split type processing of split structure, becomes processing simply, installation is convenient to, single parts
It replaces and is also convenient for after damage, due to the press fitting of " Z " font link block and the effect of positioning key, also ensure its precision and monoblock type
Structure is consistent.
Left clump weight and right clump weight ensure its balance and inertia.
The integral structure of nodular cast iron casting casting is conducive to process and safeguard, while also ensures its wearability.
The left bent axle and right bent axle are pressed " Z " font link block using heat pressing process, can ensure its matching relationship,
Achieve the purpose that interference fit.
The screw thread of screw ensures its reliability for the anti-down rotatable structure of two-part.
