PURPOSE:To permit manufacture of the captioned compressor even by means of a conventional machining technique by offsetting the assembly error by means of a joint part installed onto the crank shaft of a compression element, in a rotary compressor equipped with a plurality of compression chambers, namely a plural-cylinder rotary compressor. CONSTITUTION:Each compression element 3a, 3b is independently assembled with each cylinder 26a, 26b, upper bearing 28a, 28b, lower bearing 27a, 17b, roller 5a, 5b which eccentrically moves in each compression chamber 16a, 16b composed of these above mentioned three parts descrived the above, and each crank shaft 6a, 6b used for the eccentric movement of the roller 5a, 5b. The rotor which is fixed onto the motor shaft formed integrally with the crank shaft of the compression element which is closest to a motor among a plurality of independent compression element 3a and 3b is supported, by said compression element, and said compression element is fixed onto a chamber, and other compression element are heaped-up successively onto the before mentioned compression element, and the power transmission between the contiguous compression elements is performed with the joint installed onto the crank shafts of the both compression elements, and thus the error is offset. |
