用于PTO传动轴的棘轮扭矩限制器SA系列

A ratchet torque limiter is a device that interrupts power transmission in the event of a torque spike or overload exceeding the setting. After removing the cause of the overload, the torque limiter will automatically re-engage. Ratchet torque limiters are typically used to protect appliances subjected to constant or alternating torque from overloads.

Advantages of Ratchet Torque Limiter

One of the biggest advantages of ratchet torque limiters is that they protect against overload. They work in a similar way to a 1:1 transmission when the torque is less than a predetermined value. Once the torque exceeds the limit, the limiter acts as a clutch and removes inertial energy from the drive train. They operate in milliseconds, making them suitable for a wide range of applications, including conveyors, assembly lines, textile machinery, and printing machines.

这种扭矩限制器通常由硬化钢制成，无间隙。它具有用于调节限位的附加弹簧。它有多种型号，包括气动、液压和机械。根据扭矩限制器的用途，它可以安装在不同的位置。正常使用时，无需对其进行调整。发生故障时，用户只需断开螺旋钻，即可恢复 PTO 功能。

One of the advantages of the ratchet torque limiters for PTO驱动轴 is that they don't waste any energy, allowing you to tow the vehicle. Without this technology, towing would be impossible. Besides, a PTO ratchet torque limiter is more durable than a manual limiter.

Another major benefit of a PTO ratchet torque limiter is that it offers a safety measure if a PTO-driven implement jams. A small farm tractor can give up when running at 3800 RPM, and if it suddenly stops, the PTO shaft can also fail. The torque limiting device is the first line of defense against such catastrophic failures, and this slip clutch device eliminates the need to change pins.
