On the market there are some safety devices placed on the input shaft of the motor. It's necessary to make a distinction between that type of torque limiter and the SOTL system that Italplant has patented (Safety Output Torque Limiter). This safety device is essential for the protection of your machines and operators that may be involved in a "jamming" of the body against the dial plate.
A simple torque limiter safety placed at the entrance of the gearbox, has the only function of protecting the main organ transmission, id est the indexer and the cam followers of it, which are the weakest indexer parts. Absolutely does not protect either the machine or people who might come into contact with the stations. The protection on the input shaft of the gearbox protect only the indexer by any panic stops and restarts of the machine in a stage of operation in which the law of motion indexer has the same coefficient of maximum acceleration. Completely different is the benefit of a torque limiter located at the output indexer, that we equip also with fine adjustment of the torque that it can transmit (ATT - Adjustable Transmission Torque). This is because, if there is a jam or a contact which could cause an increase in torque above what calculated for the movement of the machine, the same causes the mechanical detachment of throughout the motorization and the disjunction indexer from the dial plate. Simultaneously, the security system patented by Italplant protects the indexer stopping the machine and avoids a possible contact of the stations of the disc with an obstruction or a human body: this can prevent an accident.
EXTERNAL TORQUE LIMITER - LCI
The Italplant external torque limiter LCI is a security system that is positioned outside of the rotary table. Docked at the output of the indexer, in case of overload, beyond a certain torque it releases the load carried by the disc. This is possible due to its internal springs, which apply an axial force that keeps in touch the surfaces of the two parts, until the release.
SAFETY INPUT TORQUE LIMITER - SITL
Italplant torque limiter, equipped with an high capacity spring release system, is useful in all those cases where it is necessary to protect a transmission from overloads, shocks and any other torque irregularities.
- Built-in in the wormgearboxes
- Protected from any possible polluting agents
- It is easily adjustable from outside by turning a standard hexagonal nut
- It can slip for several minutes at a time without damage
