A Shearing Yoke is a component used in agricultural machinery, typically in systems like rotavators, mowers, or other implements that require a connection between the tractors PTO (Power Take-Off) shaft and the working machine. It is designed to protect the machinery from damage in case of overload or impact.
Function:
The primary function of a shearing yoke is to act as a safety feature. It is designed to shear off or break under excessive load or shock, preventing damage to the PTO shaft, gearbox, or the connected implement.
It works similarly to a shear pin or slip clutch, absorbing sudden forces that could otherwise damage more expensive components of the machinery.
Material:
Shearing yokes are typically made from high-strength steel or forged metal to handle the typical working load but are engineered to break under excessive stress, thus protecting the rest of the machinery.
Design:
The yoke usually has a splined or U-joint design to connect the PTO shaft to the implement (like a rotavator, mower, etc.).
It may have an integrated shear pin or a specific weak point that is intended to break under excessive strain, allowing the rest of the system to remain intact.
Safety:
It is an important safety feature that ensures the tractor and implement are not damaged in case of sudden resistance, like hitting a rock or a dense, tough patch of soil.
By breaking the yoke instead of the PTO shaft or gearbox, it saves significant repair costs.
Lubrication:
Many shearing yokes come with greaseable parts to ensure smooth operation and reduce wear during use, helping extend the lifespan of the component.
Corrosion Resistance:
They are often treated with anti-corrosion coatings or finishes to prevent rust and deterioration when used in wet or muddy conditions.
Protection of Machinery: Prevents damage to the PTO shaft, gearbox, or implement by breaking under excessive load.
Cost-Effective: Reduces the need for costly repairs by preventing more serious damage to expensive parts.
Safety: Reduces the risk of damage to the operator or machine in case of sudden overloads.
In summary, a shearing yoke is a safety device used in agricultural machinery that protects the PTO system and implements by shearing under excessive load, preventing damage to critical parts. It is made of durable materials but designed to break under extreme conditions to safeguard the rest of the equipment.
