ENCLOSED COMPRESSOR
Document Type and Number:
Japanese Patent JP2006132333
Kind Code:
A
Abstract:
To provide a highly reliable and high quality enclosed compressor which prevents deformation of a crank shaft and coming-off of an oil pump case when mounting an oil pump case in a oil feed hole of a crank shaft.
In a mounting method of an oil pump case 6 in an enclosed compressor, a female screw is formed in the inner periphery of an oil feed hole in the bottom end of a crank shaft 4 and fixed to the bottom end of a crank shaft 4 by being screw-coupled with a male screw formed in the oil pump case 6, which facilitate mounting of the oil pump case 6 onto the crank case 4 and prevents deformation of the crank shaft due to press-fitting and coming-off of the oil pump case.
