Scroll type air compressor

Abstract

A scroll type air compressor provided by the invention utilizes an L-shape mounting frame for respectively mounting a compressor and a generator to a first mounting section and a second mounting section thereon. The generator is mounted to the second mounting section via a plate and is capable of being fine-tuned in displacement with respect to the plate, such that a second end surface of a second drive pulley of the generator can be made coplanar with a first end surface of a first drive pulley of the compressor. The position of the plate can also be adjusted up and down with respect to the second mounting section to a required position so that the distance between the drive pulleys of the generator and the compressor can be adjusted and the tension of a transmission belt can be determined.

What is claimed is: 
     
         1 . A scroll type air compressor, comprising:
 a mounting frame comprising a first mounting section and a second mounting section;   a compressor, mounted to the first mounting section of the mounting frame, the compressor comprising a first drive pulley having a first end surface perpendicular to the first mounting section when the compressor is mounted to the first mounting section;   a plate, fine-tunable in displacement with respect to the second mounting section and mounted to the second mounting section;   a generator, mounted to the second mounting section via the plate, the generator comprising a second drive pulley having a second end surface perpendicular to the first mounting section when the generator is mounted to the second mounting section, the generator being fine-tunable in displacement with respect to the plate in such a way that the first end surface is coplanar with the second end surface; and   a transmission belt engaged with both the first drive pulley and the second drive pulley, the generator driving the compressor to operate by driving the transmission belt;   wherein the plate is fine-tuned in displacement with respect to the second mounting section so that the transmission belt is adjusted to bear a predetermined tension.   
     
     
         2 . The scroll type air compressor of  claim 1 , wherein the first mounting section has orientation of a first direction and the second mounting section has orientation of a second direction; wherein the first direction is a rotation and axial direction of the compressor and the generator. 
     
     
         3 . The scroll type air compressor of  claim 2 , wherein the generator is fine-tunable in displacement with respect to the plate along the first direction, the plate is fine-tunable in displacement with respect to the second mounting section along the second direction, and the generator drives the transmission belt along the second direction. 
     
     
         4 . The scroll type air compressor of  claim 2 , wherein the second mounting section of the mounting frame comprises a plurality of longitudinal holes extending along the second direction and the plate along with the generator are mounted to the second mounting section by using a plurality of screws passing through the plurality of longitudinal holes. 
     
     
         5 . The scroll type air compressor of  claim 1 , wherein the mounting frame is an L-shape frame, with the first mounting section and the second mounting section perpendicular to each other. 
     
     
         6 . The scroll type air compressor of  claim 1 , further comprising a fixing frame fixed to both the compressor and the generator.
