METHOD OF MANUFACTURING PIN HOLDING RING FOR INTERNAL GEAR, INTERNALLY MESHED PLANETARY GEAR STRUCTURE, AND HYDRAULIC MOTOR AND PUMP |
摘要 |
A method of manufacturing a pin (roller) holding ring for a gear mechanism in which external gears (5a, 5b) are meshed internally with an internal gear (20) comprising a pin (roller) holding ring (110) having semi-circular pin (roller) holding holes in the inner peripheral side and pins (rollers) (11) close-fitted rotatably in these pin holding holes, the method comprising the steps of drilling fully circular pin holding holes (113a) in a ring base material before the inner diameter DA of a pin holding ring base material (151) is machined to a finish diameter, and expansion-machining the inner diameter of the pin holding ring up to a finish diameter after the inner surfaces of the pin holding holes have been surface-finished by a roller burnishing machining so as to provide the pin holding ring having semi-circular pin holding holes, whereby the sliding rotation of the pins in the pin holding holes can be improved. |
