TT  Torque Tender - 1

Overload Protection Equipment TORQUE LIMITERS TORQUE LIMITERS Overload Protection Equipment TORQUE LIMITERS Application Semiconductor manufacturing equipment, textile machinery, printing machinery Detecting an Overload Reliably and Taking Appropriate Action to Protect the Machine against Overload This torque limiter detects an overload and disconnects the input side and the output side immediately to protect the machine. Because it is the one-position engagement type, when the overload is removed, the input and output are automatically connected with the same torque in the same indexing position. In contrast to the friction type, this type can be used even in adverse environments. Drive key Spring slide Torque spring Figure A Spring bearing 1. Normally the drive key is engaged with the groove of the housing to transmit torque. (Figure A) 2. If an overload is applied, the drive key is tilted against the force of the torque spring and disconnected from the groove of the housing to disconnect the input side and the output side. (Figure B) 3. When the input side and the output side are returned to the original indexing position after removing the overload, the operation can be restarted with the torque that was set originally. 4. The normal and reverse rotation torque can be changed by independently connecting normal and reverse rotation torque springs. (Please contact Miki Pulley for details.)

Overload Protection Equipment TORQUE LIMITERS TORQUE LIMITERS Torque Limiters Options Signal Pin Unattended or remotely controlled machines and equipment require equipment that detects an overload and automatically switches off the power or sounds a warning alarm. An overload can be detected by connecting the signal pin to the torque tender. When an overload is detected, the input side and the output side are disconnected and the cam mechanism of the torque tender hub pushes the signal pin out in the radial direction. This can be used to switch off the power or sound a warning alarm....
