APPARATUS FOR FIXING CYLINDER OF COMPRESSOR

摘要

PURPOSE: An apparatus for fixing a cylinder of a compressor is provided to reduce vibration and noise by improving fixing structure of a cylinder assembly mounted in a hermetic container. CONSTITUTION: An apparatus includes an electromotive mechanism part(M) mounted in a hermetic container(10) to generate rotary force; a cylinder assembly(D) having an upper bearing(40) and a lower bearing(50) covering and coupled to both sides of a cylinder(30) to form a hermetic inside space; a wavy partition(22) inserted to the upper bearing and the lower bearing of the cylinder assembly in such a manner that the partition penetrates the upper bearing and the lower bearing, and placed on one side of a rotary axis(20) rotated by the electromotive mechanism part to partition the inside space of the cylinder assembly; and a fixing member(130) fixing the cylinder assembly to the electromotive mechanism part to be separated from the hermetic container by fixed gap. The fixing member comprises three fixing bars supporting the cylinder on three spots. The fixing bar has one end, a cylinder supporting part(132) welded and coupled to one side of the cylinder, and the other end having a male screw part(133) formed thereon, inserted to a fixing hole(m1) formed on a stator(m) of the electromotive mechanism part, and fixed by a nut(134).
