Title:
TORQUE LIMITER
Document Type and Number:
WIPO Patent Application WO/2018/043486
Kind Code:
A1
Abstract:
The purpose of the invention is to provide a torque limiter that can transmit a large torque without backlash when transmitting rotation and for which fluctuation in resistance torque is small. Provided is a torque limiter, wherein a shaft-shaped inner ring (2), an interior ring (3) surrounding the inner ring (2), and a pair of exterior rings (4) disposed on both sides of the interior ring (3) are installed in a housing (1) so as to have a common central axis. The inner ring (2) and the interior ring (3) are engaged so as not to rotate relative to each other, the pair of exterior rings (4) and the housing (1) are engaged so as not to rotate relative to each other, and a conical face formed on the outer peripheral face of the interior ring (3) is pressure welded to an opposing conical face formed on the inner peripheral face of the exterior rings (4). When a rotational torque of a prescribed value or greater is applied between the inner ring (2) and the housing (1), the inner ring (2) and the housing (1) rotate relative to each other against the frictional force between the conical face of the interior ring (3) and the opposing conical face of the exterior ring (4).
