Two-stage reduction gear device using a helical gear

摘要

(57) [summary] [purpose] In the two-stage reduction gear device using a helical gear, to reduce the thrust force acting on the low speed of the output shaft to support the small thrust bearing of the fluid lubricating action. The [Configuration] In the two-stage reduction gear device using helical gears, the intermediate shaft 2 and output shaft 3, the tapered surface 13A of the rolling contact to face each other, a thrust collar 13 provided with a 14A to the distal end are provided, respectively, the output shaft 3 is supported by the thrust bearing 10.
