DEVICE FOR STREAM sonochemical clean parts ROLLING BEARING AND METHOD OF ITS SIZE READJUSTMENT for specific parts to be cleaned

摘要

FIELD: process engineering.;SUBSTANCE: invention relates to in-line sonochemical cleaning of roller bearing elements and to method of its readjustment. Proposed device comprises one or several sources of equal-frequency ultrasound oscillations with flat equal-size radiating surfaces and gravity conveyor chutes replaced depending upon element type size to make elements roll by gravity parallel with radiating surfaces. Distance from conveyor trajectory plane to radiating surfaces along normal line does not exceed one-and-a-half wave length of ultrasound oscillations in solution. Conveyor trajectory nearby chute for outer races is located at the distance from normal lines running from geometrical centers of radiating surfaces not exceeding 15% of maximum size of radiating surface perpendicular to conveyor trajectory. Conveyor trajectory nearby chute for inner races and balls is located at the distance of 1/2…3/4 of said size. Proposed method consists in replacing the chute to suit type size of cleaned bearing, setting acoustic power of ultrasound oscillation sources and conveyor stroke. Conveyor stroke cycle required for cleaning in seconds is determined mathematically.;EFFECT: higher efficiency of cleaning.;2 cl, 7 dwg
