Description
Technical field
The utility model relates to a kind of motor compressor, belongs to the technical field of machinery.
Background technique
The exhaust emissions of vehicle is the principal element of pollution of atmosphere.The city with high density vehicle is particularly outstanding.In the past few years for improving toxic emission, various places government launches respectively various preferential policy to promote that environmental protection vehicle develops.
Pure Electric Transit big bus is a kind of environmental protection vehicle of zero-emission, and obtain big or middle city and generally approve, development prospect is wide.
Because the transmission of electric energy is convenient, the power of its compressor no longer needs motor directly to provide, and therefore becomes motor compressor.
At present, the whole dependence on import of electric bus air condition compressor or overseas-funded enterprise manufacture.Its structure is motor direct connection compressor, with the direct cool motors stator and rotor of refrigeration agent return-air; Compressor arrangement is eddy type.Its feature: 1, overall structure is long; 2, expensive; 3, scroll compressor reasons in structure refrigerating capacity is less, has certain limitation to the travelling comfort of automobile; 4, rotating speed is high, noise is large.
Model utility content
The purpose of this utility model is to provide a kind of compact structure, noise is little, Safety performance is high motor compressor.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of motor compressor, comprises motor and compressor, described motor and compressor arranged in parallel, be with by PK between the main shaft output terminal of motor and the main shaft input end of compressor and be connected; The casing of motor offers gas-entered passageway, and gas-entered passageway is looped around the stator exterior of motor, one end of gas-entered passageway and the casing ft connection of motor, and the other end of gas-entered passageway is communicated with the swash plate chamber in compressor, piston compression chamber successively; The casing of compressor offers exhaust passage, one end of exhaust passage and the casing ft connection of compressor, the other end of exhaust passage is communicated with piston compression chamber; In integral structure between the casing of motor and the casing of compressor.
As the further setting of such scheme, described motor is thulium permanent magnetism gear.Thulium permanent magnetism gear is lightweight, efficiency is high, and efficiency can reach about 95%, and can facilitate and change motor speed as required, to reach the object of compressor " change discharge capacity ".
Described compressor is oblique tray type compressor.Oblique tray type compressor can choose arbitrarily required discharge capacity in the broad range of 100 to 500ml/r.The main shaft of oblique tray type compressor rotates, and makes the swash plate be anchored on main shaft promote piston and make axially reciprocating in piston compression chamber, complete the compression to refrigeration agent.Be characterized in that compact structure, noise are little, it is little to vibrate; And the volumetric efficiency during slow-speed of revolution is high.
The utility model motor compressor mainly contains following beneficial effect:
1. motor and compressor arranged in parallel, and in integral structure between the casing of motor and the casing of compressor, make compact overall structure.
2. be connected by PK band between motor with compressor, reduce rotational noise.
3. well-known, motor needs cooling, general motor compressor is directly passed between the rotor of motor and stator by refrigeration agent return-air (containing refrigeration oil), make iron core, permanent magnet, particularly coil long period of soaking is in refrigerant gas and refrigeration oil, be the hidden danger of motor, likely cause serious consequence.The utility model motor compressor then have employed motor stator exocoel cooling technology, makes refrigerating agent containing oil and stator, rotor, coil completely isolated, adds reliability and Security that motor uses.
The utility model motor compressor, is particularly useful for Electric Transit big bus.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model motor compressor;
Another kind of sectional structure schematic diagram during Fig. 2 to be the utility model be display refrigerant gas circulation path.In figure, filled arrows represents air inlet path, and hollow arrow represents exhaust pathway.
Embodiment
As shown in Figure 1 and Figure 2, the utility model motor compressor, comprises motor and compressor.Wherein, motor and compressor arranged in parallel, be with 5 to be connected by PK between the main shaft output terminal 4 of motor and the main shaft input end 6 of compressor; The casing 1 of motor offers gas-entered passageway 2, the stator 3 that gas-entered passageway 2 is looped around motor is outside, one end of gas-entered passageway 2 and casing 1 ft connection of motor, the other end of gas-entered passageway 2 is communicated with the swash plate chamber 9 in compressor, piston compression chamber 7 successively; The casing 8 of compressor offers exhaust passage 10, one end of exhaust passage 10 and casing 8 ft connection of compressor, the other end of exhaust passage 10 is communicated with piston compression chamber 7; In integral structure between the casing 1 of motor and the casing 8 of compressor.
When the utility model motor compressor is installed, its motor and compressor preferably adopt the horizontal layout that is parallel to each other.
In the present embodiment, motor is preferably thulium permanent magnetism gear.Compressor is preferably oblique tray type compressor.
Meanwhile, in the present embodiment, the larger parts such as the casing 1 of motor, the casing 8 of compressor and case lid all preferably adopt silumin squeeze casting, strictly control wall thickness, to reach light-weighted requirement.
Working principle of the present utility model is as follows:
In gas-entered passageway 2, refrigerant gas after cool motors imports the swash plate chamber 9 of compressor, then cool, the slip of lubricate compressors, rolling friction pair, then import after piston compression chamber 7 completes compression, discharge through exhaust passage 10.
Above-described embodiment only illustrates inventive concept of the present utility model for explaining, but not the restriction to the utility model rights protection, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should fall into protection domain of the present utility model.
