Title:
ROTATION TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2006220282
Kind Code:
A
Abstract:
To resolve a problem in a conventional rotation transmission device using gears wherein reduction of friction generated in a sliding contact portion of mutually meshed gears is desired.
The device for carrying out rotation transmission between gears is provided with at least a worm gear 20 which is an input gear, and an output gear 25 which is an output gear. The mutually meshed gears slidably contact via grease using ester oil and/or ether oil as base oil. By forming a hard carbon thin film on a sliding contact face of at least one of the mutually meshed gears, and providing a hydrogen content of the hard carbon thin film at twenty atomic percent or less, extensive reduction of the friction in the sliding contact portion is realized.
