Deserti Meccanica SGR Series

Torque limiters of the “backlash-free” series are safety devices which protect mechanical components that are subject to repeated and different kinds of overload but where it is recommended to maintain a fixed and determined point of transmission. RADIAL/TORSIONAL VALUE = 0 FUNCTIONING Any overload in the movement system caused by exceeding the predetermined torque value causes disengagement of the device, separating the driving part from the driven. Torque is transmitted from the hub to the pressure flange through rollers “A” lodged in special “copied” housings. The rollers are pushed by the moving part, transmitting the back-lash free torque limiter in both senses of rotation. On exceeding working torque the rollers exit their respective housing, generating the shifting of the moving component and the consequent stopping of the transmission, intercepted by an electric micro-switch which further brings about the stop (signaled) of the driving part. APPLICATION The great precision of “backlash-free” torque limiters means that they can be used in all mechanical transmissions where disengagement of the drive must absolutely not cause shifting in the fixed movement points: step by step systems, automatic machines, machine tools etc. The various versions of “backlash-free” torque limiters- mechanical-pneumatic-laminar sprocket-for intromitters – mean that they can be applied to meet every specific need
