Definitions
- the present invention relates to a compressor for which ease of production is provided.
- the circulation of the refrigerant used for cooling is provided by a compressor (1 ').
- the motor (2') is comprised of two main components, the stator (3') and the rotor (4').
- the magnetic field created in the motor (2') rotates the rotor (4') and the crankshaft (5') secured press-fittingly on the rotor (4') also rotates.
- the rotational motion of the crankshaft (5') is transmitted to the piston by the piston rod and the crankpin, providing the back and forth motion of the piston.
- the compressor (1 ') furthermore comprises an oil suction pipe (6') secured at the end of the crankshaft (5') ( Figure 1).
- the rotor has to be selected to be suitable with the diameter of the crankshaft since crankshafts with different diameters are used in different types of compressors having variable powers and since the rotor is secured press-fittingly to the crankshaft made of casting material. This creates difficulties in both production and assembly and also in storage.
- the aim of the present invention is the realization of a compressor for which ease of production and assembly is provided.
- the compressor realized in order to attain the aim of the present invention comprises a rotor that is secured press-fittingly to the oil suction pipe without being in contact with the crankshaft.
- the only mechanical connection of the rotor is with the oil suction pipe.
- the length of the crankshaft can be shortened by means of the rotor being press-fittingly secured to the oil suction pipe without being in contact with the crankshaft. This provides to reduce cost of the crankshaft, that is produced of cast material and having a higher cost than the oil suction pipe. [0010] Moreover, the rotor, secured on the oil suction pipe independently from the crankshaft, is enabled to be used in different types of compressors without modification. By means of the present invention, advantages are provided for the producer in production and storage since the same rotor can be used with the crankshafts of variable diameters.
- the length of the crankshaft can be shortened to remain in the bearing.
- the oil suction pipe is mounted inside the crankshaft press-fittingly.
- the oil suction pipe is mounted press-fittingly on the crankshaft from outside the crankshaft.
- the oil suction pipe is mounted on the crankshaft from outside the crankshaft by means of a fastening element.
- the oil suction pipe is inserted into the crankshaft and secured on the crankshaft by screwing from outside the crankshaft.
- the oil suction pipe is mounted on the crankshaft by screwing.
- Figure 1 - is the schematic view of a compressor in the conventional art.
- Figure 2 - is the schematic view of the compressor in the present invention.
- Figure 3 - is the cross-sectional view of the oil suction pipe and the rotor mounted to each other press-fittingly.
- Figure 4 - is the cross-sectional view of another version of the embodiment in Figure 3.
- Figure 5 - is the cross-sectional view of the oil suction pipe and the crankshaft secured to each other by using a fastening element.
- Figure 6 - is the cross-sectional view of another version of the embodiment in Figure 5.
- Figure 7 - is the cross-sectional view of the oil suction pipe and the crankshaft secured to each other by screwing.
- Figure 8 - is the cross-sectional view of another version of the embodiment in Figure 7.
- the compressor (1) comprises a motor (2) composed of two main components, a stator (3) and a rotor (4), a crankshaft (5) that transmits the motion received from the motor (2), a cylinder block (7) and a bearing (8) for the crankshaft (5) to bear on the cylinder block (7) in the radial direction and an oil suction pipe (6) secured to the end of the crankshaft (5) for aspirating the oil.
- the rotor (4) is secured to the oil suction pipe (6) without being in contact with the crankshaft (5) ( Figure 2).
- the rotor (4) is secured on the oil suction pipe (6), preferably by press-fitting, and such that the only physical connection thereof is with the oil suction pipe (6).
- the rotational motion of the rotor (4) is transmitted to the crankshaft (5), not in contact with the rotor (4), by means of the oil suction pipe (6) whereon the rotor (4) is secured.
- crankshaft (5) While the crankshaft (5) is secured in place, the rotor (4) is mounted to the oil suction pipe (6) coaxially.
- the assembly of the rotor (4) is completed by securing the oil suction pipe (6), with the rotor (4) thereon, to the end of the crankshaft (5).
- the magnetic field created in the motor (2) rotates the rotor (4) and thus the oil suction pipe (6) press-fittingly secured to the rotor (4) and the crankshaft (5) to which it is mounted, also rotates.
- the rotation of the crankshaft (5) is transmitted to the piston by the piston rod and the crankpin, moving the piston back and forth thereby operating the compressor (1).
- crankshaft (5) is shortened by mounting the rotor (4) to the oil suction pipe (6) instead of the crankshaft (5). Shortening the length of the crankshaft (5) allows reducing the cost of the crankshaft (5) which is preferably produced of cast material.
- the same rotor (4) can be used in different types of compressors (1) wherein crankshafts (5) with different diameters are used by mounting the rotor (4) to the oil suction pipe (6).
- This provides both production and storage advantages.
- the same rotor (4) can be used in a compressor (1) having a 19 mm. crankshaft (5), by inserting the oil suction pipe (6) into the crankshaft (5) (The wall thickness of the oil suction pipe (6) is 1 ,5 mm.).
- the air gap between the rotor (4) and the stator (3) can be adjusted more properly and conveniently. Moreover, the damages incurred during mounting the rotor (4) to the crankshaft (5) can be prevented.
- the oil suction pipe (6) can be fastened to the crankshaft (5) either press-fittingly, by using a fastening element or by screwing for transmitting the rotational motion of the rotor (4), mounted to the oil suction pipe (6), to the piston rod and the piston.
- the oil suction pipe (6) is partially inserted into the crankshaft (5) and secured press-fittingly to the crankshaft (5).
- the diameter of the crankshaft (5) does not change ( Figure 4).
- the oil suction pipe (6) is secured press-fittingly to the crankshaft (5) such that the end of the crankshaft (5) is partially encircled ( Figure 3).
- the oil suction pipe (6) is inserted into the crankshaft (5) and is secured to the crankshaft (5) by using a fastening element (screw etc.) from above the portion of the crankshaft (5) corresponding to the place wherein the oil suction pipe (6) is inserted ( Figure 6).
- the oil suction pipe (6) is secured to the crankshaft (5), partially surrounding the crankshaft (5), by using a fastening element from above the portion surrounding the crankshaft (5) ( Figure 5).
- grooves are opened on the oil suction pipe (6) and on the inner and outer surfaces of the crankshaft (5).
- the oil suction pipe (6) is secured inside or outside the crankshaft (5) by screwing via these grooves ( Figure 7 and Figure 8).
- crankshaft (5) is shortened by driving in the rotor (4) to the oil suction pipe (6).
- the same type of rotor (4) is enabled to be utilized in compressors (1) wherein crankshafts (5) with different diameters are used by driving in the rotor (4) to the oil suction pipe (6).
- ease of mounting and dismounting the compressor (1) is provided, minimizing the damages to the crankshaft (5) and the rotor (4) during these processes.
- the time period required for the process of adjusting the air gap between the rotor (4) and the stator (3) is reduced, providing ease of assembly.
