Torque Limiter SLQ 28
Features
PT Tech’s SLQ series is a friction torque limiter designed for standard torque and energies. This is an economical way to protect your expensive drive train from shockload damage, while allowing your equipment to continue to perform. No resetting is required after shockloads occur and torques are pre-set by your design staff. PT Tech has other model torque limiters for applications requiring greater torque capacity within the same diameter as the SLQ series.
Technical Specs
Torque Settings
A SLQ Series torque setting is preset at the factory. When the drive system torque exceeds the torque setting, the torque limiter will slip while continuing to transmit torque equal to the setting. This is possible because the static and dynamic coefficient of friction of the disc pack is almost identical due to proprietary design.
The SLQ series torque limiter is designed to operate at motor speed. In most drive systems the prime mover represents approximately 90-95% of the equivalent inertia. The SLQ series will generally provide excellent inertial shockload protection when located at the prime mover.
Application Assitance
PT Tech has analyzed hundreds of drive systems in many types of equipment and industries. Our torque control expertise is available to our customers at no charge to help engineer possible torque protection.
PT Tech can provide a computerized report that analyzes your drive system and helps determine the need for torque protection. The computer generates a torque analysis graph comparing the maximum torque in the drive system, with and without a TLC torque limiter, under various jam conditions. Also, PT Tech has developed a unique test stand that can simulate shockloads generated by the inertia of motors up to 2,500 HP.
