摘要： Provided is a reciprocating compressor having a structure in which friction losses between a shaft and a bearing can be reduced without impairing the ability of the bearing to support the shaft. A reciprocating compressor (100) includes a cylinder (5), a piston (4), a connecting rod (6), a shaft (1), and a bearing (2). The shaft (1) has a journal portion (28) as a portion covered by the bearing (2). The journal portion (28) has a first journal portion (7) located closer to the connecting rod (6) with respect to a midpoint M of the journal portion (28) in a direction parallel to a rotational axis and a second journal portion (8) located farther from the connecting rod (6) with respect to the midpoint M. The bearing (2) has a first sliding portion (10) for supporting the first journal portion (7) and a second sliding portion (11) for supporting the second journal portion (8). The first sliding portion (10) has a first recessed portion (29) in at least one range selected from a range of 0° to 180° and a range of 270° to 360° in a rotational direction of the shaft (1) from a reference position.

摘要： A closed compressor (10A) includes: a compressor body (100); and a closed vessel (200) in which the compressor body (100) is accommodated and oil is stored. The compressor body (100) has an electric element (110) and a compression element (120) that is driven by the electric element (110). The compression element (120) has a cylinder block (122) that forms a cylinder, a piston (123) that performs a reciprocating motion in the cylinder, and a crankshaft (124) that actuates the piston (123). The cylinder block (122) configures a bearing (125) that pivotally supports the crankshaft (124). The cylinder forms a compression chamber (126). The compressor body (100) has a support (300) that forms a curved surface (301). A contact portion, at which the curved surface (301) comes into contact with a receiving surface in the closed vessel (200), is formed.

摘要： PROBLEM TO BE SOLVED: To provide a reliability-enhanced hermetic compressor to be driven by an inverter circuit, in which, in order to improve oil shortage when starting the hermetic compressor, the compressor is operated at a commercial frequency until oil for starting is accumulated in an oil storage groove and then the oil is supplied from the oil storage groove to a lower race.SOLUTION: When operating a hermetic compressor at less than a commercial frequency, the compressor is operated at the commercial frequency until oil 103 for starting is accumulated on an upper surface of a lower race 169 of an oil storage groove 184, and a lubrication state can be stabilized and reliability can be enhanced by quickly supplying sufficient oil to an upper race 161 and the lower race 169. Since the oil 103 supplied from a main shaft part 123 can be stored in the oil storage groove 184 by collecting the oil 103 by an oil fence 180, oil can be sufficiently supplied from the oil storage groove 184 to the lower race 169 and a contact state between a ball 165 and the lower race 169 can be stabilized, so that the ball 165 and the lower race 169 can be prevented from being damaged.

摘要： PROBLEM TO BE SOLVED: To provide a hermetic compressor having an improved efficiency and reliability, by improving an oil feed speed at the start-up, while reducing a sliding loss of the hermetic compressor driven by an inverter using a viscous pump.SOLUTION: The hermetic compressor includes: in a cylindrical cavity part 160 below a shaft 118, the viscous pump 150 comprising an insertion part 166 and a helical groove 176 formed of an inner periphery of the cylindrical cavity part 160 and an outer periphery of the insertion part 166; and a centrifugal pump 152 with a rotation synchronization means 178 for closely bringing a lubricating oil 104 in the cylindrical cavity part to a rotational speed of the shaft 118. The centrifugal pump is arranged on the upper part of the viscous pump, thereby reducing friction between the outer periphery of the insertion part of the viscous pump and the inner periphery of the cylindrical cavity part, resulting in reducing input and improving efficiency. Also, by disposing the centrifugal pump on the upper part of the viscous pump, an oil feeding time of the lubricating oil to the sliding part at the start-up is shortened, and the occurrence of wear at the sliding part is suppressed, thereby reducing the input to improve the efficiency and the reliability.

摘要： PROBLEM TO BE SOLVED: To provide an efficient hermetic compressor by increasing a quantity of refrigerant gas flowing in a suction hole.
SOLUTION: A communication pipe 159 of a suction muffler 151 has a suction muffler outlet 157 communicating with a suction hole 141 of a valve plate 143, is disposed in such a manner as to extend in a vertical direction with respect to the axial center of the suction hole 141, and disposed in such a manner that a part of the suction hole 141 is covered by a part of the suction muffler outlet 157 positioned at a downstream side of refrigerant gas 105 flowing in the communication pipe 159 in the case of an axial direction projection of the suction hole. In the suction muffler outlet 157, an effective area of the suction hole 141 is increased by setting a side where a larger amount of refrigerant gas 105 flows closer to the center of the suction hole 141, and volumetric efficiency is improved.
