Abstract
The utility model provides a flip-over type outer rotor compressor with good balance. A crankshaft of the flip-over type outer rotor compressor is not easy to loosen. The flip-over type outer rotor compressor comprises a footing plate, a rack, a crankshaft, a connecting rod, a piston, a cylinder and a motor comprising a stator and an outer rotor, wherein supporting springs are arranged below the rack in a supporting manner; the stator (3) and the outer rotor (4) are arranged above the rack (9); counterweight holes (401) with clump weights embedded inside, which are uniformly distributed along the circumferential direction at intervals, are formed in the upper end face of the outer rotor, close to the periphery; an elastic bush (5) is arranged in the center of the upper end of the outer rotor; axial sectioned grooves (501) uniformly distributed along the circumferential direction are formed in the external section of the elastic bush; the elastic bush is sleeved in the upper end of the crankshaft (7); a hoop (8) is sleeved outside the elastic bush in an interference manner. The outer rotor compressor is used as a refrigeration compressor.
Description
Technical field
The utility model relates to compressor, particularly external rotor compressor.
Background technique
It is little that external rotor compressor has volume, the feature that moment of torsion is large.But the external rotor of its motor of external rotor compressor of the prior art is without junction at equilibrium member, in the time being used in the compressor of relatively high power, the defect that motor balance quality lowly causes is just comparatively outstanding, one of them obvious problem is vibration and the noise that motor imbalance causes, and the external rotor of external rotor electric machine is cantilever-type configuration, form for iron core adds die casting again, be difficult to work in-process once balance.In addition, the bent axle coordinating with external rotor adopts simple press mode to be assemblied in external rotor, easily produces loosening.Existing external rotor compressor is generally that external rotor is positioned at frame (compressor) below besides, and cylinder, piston are positioned at frame (compressor) top, convenient not when this can cause assembling external rotor, cause work efficiency to decline.
Summary of the invention
The utility model will solve external rotor compressor of the prior art because rotor easily causes motor oscillating and produces large noise without junction at equilibrium member, and external rotor and bent axle assembling surface of contact is short, easily produce loosening, external rotor and the bent axle inconvenient problem that is linked and packed, upside-down mounting type external rotor compressor of the present utility model is provided for this reason, this external rotor compressor electric motor balance quality is good, bent axle is not easy to become flexible, and external rotor and bent axle are linked and packed conveniently.
For addressing the above problem, the technical solution adopted in the utility model is to be provided with footing piece, frame, bent axle, connecting rod, piston, cylinder and to comprise stator and the motor of external rotor, below frame, support is provided with supported spring, its special way is that described stator and external rotor are installed on frame (compressor) top, and cylinder piston is placed in to frame (compressor) below.The nearly periphery place, upper-end surface of external rotor offers the circumferential counterweight hole of setting balancing weight uniformly at intervals, center, external rotor upper end has resilient bushing, the outer sections of this resilient bushing has circumferentially uniform axial splitting groove, in the upper end portion of described bent axle, be placed on described resilient bushing, this interference ground, resilient bushing outside overcoat has anchor ear.
The resilient bushing of center, described external rotor upper end can be and the integrated resilient bushing of external rotor.The resilient bushing of center, described external rotor upper end is placed on the resilient bushing of external rotor center hole in can being also, the periphery wall of this resilient bushing is provided with anti-rotation convex tendon or groove.
Above described footing piece, be connected with spring seat, described supported spring is connected in above this spring seat.
For the needs that adapt to AC and DC, frequency conversion can circumferentially be embedded with magnetic shoe in uniform way at the inwall of described external rotor.
Can offer keyway at the center hole perisporium of described stator, be combined with frame in stator center hole and adopt key pin combination.
In bent axle, be placed on described resilient bushing, the step that is coated to anchor ear interference resilient bushing is first anchor ear to be heated, and after heat expansion hole enlargement, is inserted in spring bushing, after the cooling undergauge of anchor ear, holds resilient bushing tightly, and resilient bushing is held bent axle again tightly.
The utility model is the circumferential counterweight hole of setting balancing weight uniformly at intervals because the upper-end surface of external rotor offers, in the time that external rotor carries out Balance Treatment adjustment by self-driving type balance, can realize at imbalance point installation balancing weight the balance of external rotor, thereby the stationarity while realizing compressor operation, to reduce vibration and noise.Again because center, external rotor upper end has resilient bushing, this resilient bushing has circumferentially uniform axial splitting groove, also be provided with the anchor ear of resilient bushing after interference ground overcoat, therefore bent axle upper end portion inner sleeve resilient bushing, interference ground, resilient bushing outside overcoat anchor ear, bent axle can be connected in to external rotor center tightly, be difficult for loosening.External rotor in the utility model and bent axle binding site, in bent axle upper end portion, are linked and packed conveniently external rotor and bent axle.The inwall of described external rotor is circumferentially embedded with the utility model of magnetic shoe in uniform way, can adapt to the needs of AC and DC, frequency conversion.
