MEANS FOR PREVENTING WEAR IN THE TRANSFORMAL WORKING MEMBERS OF HERMETIC COMPRESSOR

摘要

The abrasion preventing device of conversion mechanism in a closed electric motor compressor is capable of supplying a sufficient lubricating oil upon operation of the compressor to thereby prevent a slider and a slider shell which constitute the conversion mechanism from being abrasive. The abrasion preventing device comprises: a slider(46A) slidably coupled with the interior of a slider shell(47) and having a fixed hole(44) through which a splash bar(41) on the top end of a crank shaft(43) is passed; and first and second inducing grooves(49A,49A') formed on the both sides of the fixed hole(44), connected to first and second oil grooves(45A,45A') formed on the peripheral surface of the both sides of the slider(46A) to minimize the contact area with the slider shell(47), and for guiding oil(O) splashed from the splash bar(41).
