Abstract
A power transmission device of a steering system. A first connector includes a first coupling portion coupled to a first shaft and first supporting portions protruding axially from the first coupling portion. A second connector includes a second coupling portion coupled to a second shaft disposed coaxially with the first shaft and second supporting portions protruding axially from the second coupling portion to be circumferentially spaced apart from the first supporting portions. A damper is coupled axially between the first connector and the second connector, and includes blades supported circumferentially between the first supporting portions and the second supporting portions.

A power transmission device of a steering system, comprising:
- a first connector comprising a first coupling portion coupled to a first shaft and first supporting portions protruding axially from the first coupling portion;
- a second connector comprising a second coupling portion coupled to a second shaft disposed coaxially with the first shaft and second supporting portions protruding axially from the second coupling portion to be circumferentially spaced apart from the first supporting portions;
- and
- a damper coupled axially between the first connector and the second connector, and comprising blades supported circumferentially between the first supporting portions and the second supporting portions, wherein the damper comprises a cylindrical axial support member including a threaded portion provided on an outer circumferential surface of the cylindrical axial support member, the threaded portion having axially alternating ridges and grooves.
A power transmission device of a steering system, comprising:
- a first connector comprising a first coupling portion coupled to a first shaft and first supporting portions protruding axially from the first coupling portion;
- a second connector comprising a second coupling portion coupled to a second shaft disposed coaxially with the first shaft and second supporting portions protruding axially from the second coupling portion to be circumferentially spaced apart from the first supporting portions;
- and
- a damper coupled axially between the first connector and the second connector, and comprising blades supported circumferentially between the first supporting portions and the second supporting portions, wherein the damper comprises an axial support member having a jig hole in one or both of one side surface and an other side surface of the axial support member and an annular strength-enhancing member provided within the axial support member, the strength-enhancing member being fixedly held in the jig hole to be integrated with the axial support member.
