Powder Clutch and Brake
Characteristics
1. Highly precious wide-range control
The torque can be adjusted to fit the capacity in order to achieve wide-range control as the response is quick and accurate with the superfine processing, and the transferred torque varies.
2. Low maintenance expense
Its long life is guaranteed as it has superior resistance to heat, oxidation, corrosion and friction being composed of spherical particles of Fe, Al and Cr alloy and can be used for a long period of time without adding grease by applying the rubber cover type bearing type.
3. Stability
The material and production lines are protected as the torque needed to maintain adequate tension is transferred to the output shaft irrespective of the torque of the input shaft.
4. High reliability
It can be safety operated for a long time without an operator as the torque transferred to the output shaft can be constantly maintained and the voltage can be adjusted at all times in any circumstances.
5. Automation
The automatic tension control is achieved through the automatic tension control system built based on the unique control method and accumulated technology of Pora.
6. Shock absorbing property
Though, in case of a general electronic clutch or brake, shock is applied to the device as torque is momentarily transferred when the power is transferred, a powder brake or clutch induces generation of a slip to smoothly transfer the power giving no burden to the device at all.
Application
The powder clutch and powder brake with exceptionally superior tension control can be widely used for industrial machines as they are easy to mount and 100% conforms to international standards.
Example) It is widely used to control rewinding and unwinding tensions of industrial machines such as the resin machine, paper-makingmachine, spinning machine, wire-making machine and food machine.
