Scroll type hydraulic machine

Abstract

Abstract PURPOSE:To prevent the occurrence of vibration in a scroll compressor as well as to simplify a rotation preventive mechanism, by installing each gear in an auxiliary crank for rotation prevention and a driving shaft, while stretching a toothed belt between gears, and giving tension to this belt. CONSTITUTION:A main crank 5B for producing a swivel motion is fitted in a bearing hole 7c at the central part of a swivel scroll 7 of a scroll compressor to transmit power of a main shaft A. On the other hand, on the outer circumferential part, there is provided with a rotation preventing auxiliary crank setting part 7D in which an auxiliary crankshaft 10B is fitted. Gears 5C and 10C are installed in both these cranks, while a toothed belt 13 given tension by a pressing member 14 is stretched between these gears.
