<p>PURPOSE:To make pressure imposed on a driven shaft lower to produce a gas compressor being less in mechanical wear and high in reliability by forming the gas compressor in a rotary cylinder block type, and holding a driven shaft to which the said cylinder block has been fixed by a side plate through a bearing. CONSTITUTION:A side plate 3 is fixed to the open end plane of an approximately cup-shaped casing 1, and a driving shaft 5 having a helical bevel gear 4 fitted on it is inserted in the side of the casing 1. The one end of a driven shaft 16 to which a cylinder block 12 is fixed is engaged with the helical bevel gear 4 in inclination to it, and the other end of the drive shaft 16 is rotatably supported by a side plate 3 through a bearing 17. Pressure acting on the bearing 17 is therefore dispersed on its whole circumference to make the said pressure lower as compared with that in the case of a fixed shaft.</p> |
