Publication number: 20150093275Abstract: To fasten an auxiliary crank for prevention of autorotation of an orbiting scroll to a compressor-casing side bearing in a scroll compressor, a tool must access from a motor side to a compressor casing so as to fasten the auxiliary crank to the compressor-casing side bearing. Therefore, fastening between the auxiliary crank and the bearing cannot be made after a motor section and a compressor body are fastened together. This necessitates the steps of: separating the compressor body from the motor section; fastening the auxiliary crank to the compressor casing; and then fastening the compressor body and the motor section together. A compressor-motor integrated scroll compressor cannot be assembled in sequential steps, entailing increased assembly costs and lowered maintenability. A plurality of notches or holes is formed on a motor housing or the compressor casing.Type: ApplicationFiled: July 24, 2014Publication date: April 2, 2015Inventors: Shumpei YAMAZAKI, Yoshiyuki KANEMOTO

Publication number: 20080159894Abstract: A gap between opposing wrap portions is narrowed to increase compression efficiency, and an amount of machining time is reduced to thereby increase productivity. A plurality of proximate portions 8 are formed, at spacings in a spiral direction, on an outer peripheral surface 3B of a wrap portion 3 of a fixed scroll 1. Flat surfaces 8A are used to connect adjacent proximate portions 8. Similarly, a plurality of proximate portions 14 are formed, at spacings in the spiral direction, on an outer peripheral surface 13B of a wrap portion 13 of an orbiting scroll 11. Flat surfaces 14A are used to connect adjacent proximate portions 14. In this way, the outer peripheral surfaces 3B and 13B of the wrap portions 3 and 13 can be formed in polyangular shapes, so as to reduce a gap between the wrap portions 3 and 13 and simplify the shapes. As a result, an amount of machining time can be reduced.Type: ApplicationFiled: December 26, 2007Publication date: July 3, 2008Inventor: Yoshiyuki Kanemoto
