Abstract

In this device the power spring of a rotatable element is always tensioned to the optimum value and overloading of the spring is prevented. Rotatable element 1 is fixed to a shaft and contains in an inside portion a power spring (not shown) covered by cage 2. Cage 2 is mounted on sleeve 5 to rotate freely on the same shaft. One end of the power spring is fixed to element 1, the other end engages cage 2. Spring clutch 10 is shown as a spiral having two windings only. Clutch 10 is mounted on sleeves 5 and 6. Sleeve 6 is free to rotate on the same shaft and receives a constant torque by ratchet gear feed 7 with pawls 8 and 9.

Power Spring Energizer Overload Regulator

In this device the power spring of a rotatable element is always tensioned to the optimum value and overloading of the spring is prevented. Rotatable element 1 is fixed to a shaft and contains in an inside portion a power spring (not shown) covered by cage 2. Cage 2 is mounted on sleeve 5 to rotate freely on the same shaft. One end of the power spring is fixed to element 1, the other end engages cage 2. Spring clutch 10 is shown as a spiral having two windings only. Clutch 10 is mounted on sleeves 5 and 6. Sleeve 6 is free to rotate on the same shaft and receives a constant torque by ratchet gear feed 7 with pawls 8 and 9.

When the torque produced by the power spring, arranged inside cage 2 and supplying the power for the rotation of pin wheel 1, exceeds the torque transmitted by the ratchet gear 7, the charge limiter 12 engages the spring clutch end 11. Upon release of spring clutch 10, sleeve 6 becomes disengaged from sleeve 5. When element 1 rotates in anticlockwise direction, projecting member 14 of charge limiter 12 engages the pin 13. The latter is fixed to cage 2 so that distortions of spring clutch 10 are prevented.
