Slip Clutch PTO Shaft

Agricultural equipment is often a combination of a tractor's engine and attachments. The Slip Clutch PTO shaft transfers power from the engine to another piece of farm equipment. In the case of a tiller or bush hog, the correct spline shaft should be attached to the machine. The slip clutch PTO shaft provided by us is of high quality and gains a good reputation worldwide.

A slip clutch PTO shaft is a good option if you're not sure of what setting you need to use. The PTO slip clutch is designed to prevent overload. Unlike conventional limiters, this device will stop the machine from overextending when the torque is too high. By limiting torque, the PTO drive shaft with slip clutch prevents a machine from overheating, resulting in damage or even breakdown. And since these limiters are mechanical devices, the risk of overheating is minimized, and the torque will be distributed in the smallest possible amount. If the torque exceeds the preset limit, the PTO slip clutch will shut off and prevent further damage.

What is a PTO Slip Clutch?

You can find PTO slip clutches on most PTO-driven rotary mowers. A PTO slip clutch is a simple disc and spring device. In other words, it is a torque limiting device that limits the amount of torque that can be transferred from the tractor to the implement. Rotation at different speeds on both sides of the PTO drive shaft is achieved by sliding or freewheeling. Slip clutches are commonly used with brush rotators and rotating equipment. In addition, these PTO slip clutches can also be used with most PTO-driven equipment such as post-hole augers, hay spreaders, balers, cork saws, and other common farm equipment.

How a PTO Slip Clutch Works

A PTO slip clutch, also called a friction torque limiter, is a mechanical device that protects a system from overloading and causing damage. Proper knowledge of how they work can make it an effective, reliable, and user-friendly tool for preventing damage to critical machinery. These devices work by preventing excessive torque from being transmitted and are available in many different styles.

A slip clutch can be used to control the amount of torque transmitted by a shaft, wire, or filament. These devices are often customized with a hand-operated adjustment knob to adjust the amount of torque output. Because these devices don't have precise measurement capabilities, their results may vary by up to 10%, which is less than optimal for narrow-web unwind and rewind applications. To prevent this, use a PTO slip clutch in combination with a flexible coupling.

A PTO slip clutch works by coupling two rotating bodies, such as a motor and shafts. The slip clutch's springs exert axial pressure on the frictional discs. This frictional force allows the limiter to withstand a preset amount of slip. Once the slip clutch reaches a certain level, it stops transmitting torque and resumes its previous output. The torque transmitted during the slip period depends on the speed of the rotations, duration of the slip, the types of lubrication used, and the frictional materials. Some slip clutches can tolerate continuous slip.

Why Use a Slip Clutch PTO Shaft?

A Slip Clutch PTO Shaft protects the implement gearbox and the PTO. The patented slip clutches are easy to install and maintain. The design allows for a large number of attachments to be connected to your tractor. Adding a PTO shaft will allow you to extend the shaft, so you can continue to work on your farm.
