Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/179122
Kind Code:
A1
Abstract:
Provided is a power transmission device which is always capable of smoothly transmitting power, by effectively absorbing an impact as a result of the appropriate elastic member acting in response to the load of a torque load. This power transmission device is configured in a manner such that: first pressing projection parts 81p and second pressing projection parts 82p formed so as to project in a first rotating body 81 and a second rotating body 82, which are positioned so as to be capable of coaxially rotating relative to the rotational center axis Lc, are provided at relative positions that overlap the trajectory of rotation; a soft rubber 86a having a large elastic deformation volume and a small elastic coefficient and a hard rubber 87 having a small elastic deformation volume and a large elastic coefficient are interposed between the first pressing projection parts 81p and the second pressing projection parts 82p; and while in a state where a relative torque load is not produced between the first rotating body 81 and the second rotating body 82, the soft rubber 86 contacts both the first pressing projection parts 81p and the second pressing projection parts 82p, and the hard rubber 87a is interposed between the first pressing projection parts 81p and the second pressing projection parts 82p in a manner such that a gap exists therebetween.
