Abstract
Refrigerant compressor, comprising an electric drive unit (2), a cylinder housing (1), a crankshaft (11) which may be driven by the electric drive unit, wherein the cylinder housing (1) has the main bearing for the crankshaft (11), and a piston (12), driven by the crankshaft (11) and guided in the cylinder housing (1), which compresses the refrigerant. To allow the main bearing length to be dimensioned as large as possible, it is provided that at least one height compensation element (26) is situated between the cylinder housing (1) and the electric drive unit (2) in order to keep an overall height of the cylinder housing and the respective drive unit practically identical within a compressor family having drive units of different heights.
Claims7
1:
- Refrigerant compressor, comprising an electric drive unit (2), a cylinder housing (1), a crankshaft (11) which may be driven by the electric drive unit, wherein the cylinder housing (1) comprises the main bearing for the crankshaft (11), and a piston (12), driven by the crankshaft (11) and guided in the cylinder housing (1), which compresses the refrigerant, wherein at least one height compensation element (26) is situated between the cylinder housing (1) and the electric drive unit (2), in order to keep an overall height of the cylinder housing and the respective drive unit practically identical within a compressor family having drive units of different heights.
2:
- Refrigerant compressor according to claim 1, wherein the cylinder housing (1) has at least one contact flange (5) which is mounted on at least one corresponding contact surface of the electric drive unit (2), and the at least one height compensation element (26) is situated between the contact flange (5) and the contact surface.
3:
- Refrigerant compressor according to claim 2, wherein the electric drive unit is a single phase asynchronous motor, and the contact surface is the core stack (2) of the stator.
4:
- Refrigerant compressor according to claim 3, wherein the contact flange (5), height compensation element (26), and contact surface are screwed together.
5:
- Refrigerant compressor according to claim 1, wherein the height compensation element (26) has a borehole or recess for accommodating a fastening element, preferably a screw.
6:
- Compressor family having refrigerant compressors of different refrigerating capacities, wherein each refrigerant compressor includes an electric drive unit (2), a cylinder housing (1), a crankshaft (11) which may be driven by the electric drive unit (2), wherein the cylinder housing (1) has the main bearing for the crankshaft (11), and a piston (12), driven by the crankshaft (11) and guided in the cylinder housing (1), which compresses the refrigerant, wherein the electric drive unit (2) of each refrigerant compressor in the compressor family has a different overall height (Hoverall), composed of the height of the electric drive unit (He) and the height of the cylinder housing (Hz), depending on the refrigerating capacity, wherein at least one height compensation element (26) is situated between the electric drive unit (2) and the cylinder housing (1) of each refrigerant compressor in the compressor family.
7:
- Compressor family according to claim 6, wherein the section defining the height (He) of the electric drive unit (2) is the height of the core stack (2) of the stator.
