Abstract
An electric compressor includes a housing, a driving shaft, an electric motor, and a compression mechanism. The housing includes a first housing and a second housing. The electric motor includes a stator and a rotor. The first housing has a first end surface. The second housing has a second end surface. The first housing and the second housing are fixed by a first fastener. The stator is fixed to the first end surface by a second fastener. The first end surface has a first hole through which the first fastener is inserted and a second hole in which the second fastener is fixed.
Claims6
An electric compressor comprising:
- a housing;
- a driving shaft;
- an electric motor that rotates the driving shaft;
- and
- a compression mechanism that is driven with rotation of the driving shaft to compress refrigerant,
- the housing including a first housing extending in an axial direction of the driving shaft and a second housing having a cylindrical shape and fixed to the first housing in the axial direction,
- the electric motor including a stator formed in a cylindrical shape and a rotor that is rotatable inside the stator,
- the first housing and the second housing cooperating to form a suction chamber that is divided from an outside of the housing and into which the refrigerant is sucked,
- the first housing having a first end surface that is an annular shape and facing the second housing in the axial direction,
- the second housing having a second end surface that is an annular shape and facing the first end surface in the axial direction,
- a gasket having an annular shape and being provided between the first end surface and the second end surface and sealing the suction chamber against the outside of the housing,
- the first housing and the second housing being fixed with each other with the gasket interposed between the first end surface and the second end surface by a first fastener, wherein
- the stator is disposed in the suction chamber and fixed to the first end surface by a second fastener in the axial direction,
- the first end surface has a first hole which the first fastener is inserted through or fixed in and a second hole in which the second fastener is fixed,
- the second hole is open in the first end surface and is located on an inner side of the first hole in a radial direction of the first housing,
- the first fastener is a bolt that is located on an outer side of the stator in the radial direction of the first housing, and
- the second fastener is a bolt that is located on an outer side of coil ends of the stator and on an inner side of the first fastener in the radial direction of the first housing.
