DEBURRING METHOD AND DEVICE OF INTERNAL GEAR

摘要

PROBLEM TO BE SOLVED: To provide a deburring device for an internal gear for removing burr occurring on a complex internal gear having a plurality of internal gear sections. SOLUTION: Deburring tools 76 and 78 are mounted back to back to two sleeves 80 and 82 slidably engaging with a rotatable cutter shaft 66. A helical compression spring 94 is arranged between two sleeves, and is energized in the mutually separating direction. By rotating the internal gear 26, one 76 of the deburring tools is pressed to the inside end surface 130 having burr 124. The pressing force is adjusted by adjusting an elastic force of the spring by adjusting the axial position of the cutter shaft 66. The burr 124 is removed while the deburring tool rotates following the internal gear 26. A common spring 94 is used also when the deburring tool 78 is pressed on the other inside end surface 132 having burr 126. COPYRIGHT: (C)2005,JPO&NCIPI
