Title:
過負荷防止機構付き角度位置保持装置
Document Type and Number:
Japanese Patent JP6854313
Kind Code:
B2
Abstract:
A small and compact rotation transmitter is provided by combining a torque limiter as an overload prevention system and an angular position holding apparatus like a torque hinge. An outer race member (4) is installed in a housing (2), and a coil spring (10) is mounted on the outer peripheral surface thereof. Inside the outer race member (4), an internal space (53) having a circular cross section is formed, and an inner race member (6) is installed concentrically with the outer race member (4) . In the annular space between the outer race member (4) and the inner race member (6), a thin-plate elastic piece (8) is inserted to be pressed against the outer race member (4) and the inner race member (6), and either the outer race member (4) or the inner race member (6) is connected to an input-side device while the other is connected to an output-side device. Even when no rotation torque is input from the input-side device, the position of the output-side device is held by a braking torque from the coil spring (10) . When the rotation torque from the input-side device becomes excessive, slippage occurs on the thin-plate elastic piece (8), whereby the outer race member (4) and the inner race member (6) are disconnected.
