Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2017020536
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power transmission device capable of suppressing deterioration of durability due to abrasion and securing high torque transmission efficiency.SOLUTION: A friction wheel 13 is provided between a driving pulley 12 and a driven pulley 15. On the outer diameter surface of the friction wheel 13, a first coating 18 comprising a high-strength elastic member and a second coating 19 comprising a high-friction-coefficient elastic member are provided in parallel in an axial direction. The first coating 18 and the second coating 19 elastically contact with the driving pulley 12 and the driven pulley 15 respectively. Consequently, high torque transmission efficiency is secured by elastic deformation of the second coating 19 comprising the high-friction-coefficient elastic member.SELECTED DRAWING: Figure 3
