Abstract

DC60 (29/04/56) to provide a rotary compressor where the cam volume of the camshaft part of the shaft The crank is increased to increase the maximum volume of the compression chamber. and which will not reduce the assembly ability and prevent refrigerant leakage and can improve the compression efficiency. In a rotary compressor, where a pair of compression mechanism units 10a and 10b are stacked, in order to splice the baffles, 30 is driven by a crankshaft 50 that includes two parts, the camshafts 51a and 51b and the crankshaft. The 50 includes shaft sections 52a and 52b supported by end plates on both sides. The shafts 52a and 52b of the crankshaft 50 are formed to different outside diameters. The camshaft segments 51a and 51b of the crankshaft 50 are formed to have different outside diameters. Through holes, the center 33 of the baffle 30 is formed to have an internal diameter smaller than each diameter. The exterior of the camshaft segments 51a and 51b of the crankshaft 50 and the baffles 30 are divided for to enclose the baffle insert 53 of the crankshaft 50 to provide a rotary compressor in which the cam volume of the camshaft part of the shaft The crank is increased to increase the maximum volume of the compression chamber. and which will not reduce the assembly ability and prevent refrigerant leakage and can improve the compression efficiency.

Claims (1)

Disclaimer (all) which will not appear on the announcement page: EDIT 24/11/2016 1. Rotary compressor in which the compression mechanism is stacked in order to bond the driven baffle. The crankshaft is supported by a bearing (bearing) arranged on both ends of it, where the crankshaft will include. Two camshafts formed with different outside diameters and two camshafts formed with different outside diameters. The baffle also includes a through hole through which the crankshaft extends through. Through holes, which have a slit The inner center is smaller than each of the outer diameter of the camshaft segments. And the baffle will be divided In order to encompass the crankshaft The outer diameter of the small diameter of the crankshaft part shall not be smaller than 0.8 times and not larger than 0.9 times the outer diameter of the side shaft section, the large diameter and the outer diameter of the small diameter side camshaft of the crankshaft. Shall not be smaller than 0.86 times and not larger than 0.94 times of the outer diameter of the camshaft side. 2. The rotary compressor of the 1st claim, where the small diameter side shaft and the small diameter camshaft part of The crankshaft is set closely together, and the large diameter side shaft and the large diameter side camshaft part of The crankshaft is set closely together. 3. The rotary compressor of the 1st or 2nd right holder, where the outer diameter of the shaft section is Being deformed on the side, the small diameter of the crankshaft is 0.925 times the outer diameter of Large diameter side camshaft --------------------- 1. a rotary compressor in which a pair of compression mechanical units is stacked in order to splice Driven baffle The crankshaft includes two parts, the camshaft and the crankshaft, including the shaft. It is supported by the upper end plates, where the crankshaft shaft is formed to differ in outer diameter. And the camshaft portion of the crankshaft is formed so that the outside diameter differs, and the holes through the center of the baffle are formed to have a smaller inner diameter. Each outer diameter of the camshaft part of the crankshaft And partitions will be divided to To encompass the insert part of the crankshaft
