For micro-compressor, for guaranteeing the high efficiency of motor, its motor stator and rotor gaps generally is designed to monolateral gap 0.2～0.3mm and requires circular gap even.As adopt above-mentioned current stator and rotor and the fixation arrangement of the compression pump housing and housing, and necessarily require the precision of existing assembly technology, equipment, frock etc. significantly to improve, just reach stator and rotor gap requirement to once assembling.
The model utility content
The purpose of this utility model is to provide for above-mentioned existing problems and deficiency
OneKind is simple in structure, the adjustable structure of the Mini compressed machine rotor assembling that cost is low, and easy accessibility is convenient to adjust fit up gap between rotor and stator.
The technical solution of the utility model is achieved in that
a kind of adjustable structure of Mini compressed machine rotor assembling, comprise motor rotor core and bent axle, motor rotor core is connected with the middle mode by Spielpassung of bent axle, it is characterized in that: described motor rotor core is provided with the assembling circular port, form planar wall on the inboard aperture wall of assembling circular port, bent axle is provided with the shaft end that coordinates with the circular interporal lacuna of assembling on motor rotor core, and be provided with planar wall on the outer wall of shaft end, the shaft end of described bent axle is fixedly connected with by the detachable mode of screw with assembling circular port on motor rotor core, the setting that is complementary of the planar wall of the planar wall of the shaft end of bent axle and motor rotor core assembling circular port.
The cross section of the assembling circular port of described motor rotor core is " D " font, and the cross section of the shaft end of bent axle is " D " font, and " D " font hole internal diameter to coordinate with " D " font axle outside dimension be 0.01～0.08 Spielpassung.
Described motor rotor core is adjusting type assembling, and because of the existence of the above Spielpassung value, the spacer shims that can stipulate by use or special tool are adjusted and keep the rotor gap.
The shaft end center of described bent axle is provided with tapped hole, and motor rotor core passes through screw lock after being inserted in the shaft end of bent axle.
The utility model compared with prior art has following advantage: the utility model is by the Spielpassung size of " D " font axle of appropriate design rotor " D " font hole and bent axle, and the detachable mode that adopts screw to be fixedly connected, can realize the convenient fit up gap of adjusting the motor stator and rotor, guarantee the efficient operation of micro-compressor motor.
