The Huco Dynatork MS worm gearbox stops rotation of the low-speed shaft whenever the stall torque exceeds the calibrated value of the internal torque limiter.
The Huco Dynatork MS worm gearbox with integral torque limiter is suitable for safeguarding machinery and the people that operate it.
It stops rotation of the low-speed shaft whenever the stall torque exceeds the calibrated value of the internal torque limiter.
In the event of a power cut this safety gearbox effectively locks and in the majority of applications this is an appropriate consequence.
For others however it is a disadvantage.
In a motorised factory door, for example loss of power can leave the door stuck open or closed.
For applications such as this Huco Dynatork has introduced the MRV50.LS safety worm gear box with a disengaging torque limiter.
A disengaging lever essentially provides a manual override so that the door can still be operated until power is restored.
The built-in torque limiter comprises a symmetrical cone on the output shaft acting against a hollow cone on the worm wheel, all rotating in an oil bath.
This gives precise adjustment and consistency in the slipping point during torque overload.
The low contact pressure between the conical hub and the worm wheel of the gearbox make constant adjustment unnecessary during the life of the product.
Thanks to use of quality materials and the inclusion of an oil bath component wear is greatly minimised.
Disengaging models are available for single, three-phase and DC operation, with 40 - 80mm centres, and the power range is 0.09 - 3kW.
These aluminium gearboxes are manufactured in Italy by TS Power Transmission.
