• Specification

• Function 

1. Torque Transmission
Function: The primary role of the coupling is to transfer torque from the power - generating source (such as an engine or a hydraulic motor) to the driven component (like a pump, transmission, or a shaft that drives a working attachment). It ensures that the mechanical power is effectively transmitted between the two shafts, enabling the machine to perform its intended tasks, whether it's digging, lifting, or other operations in the case of a Komatsu excavator or loader.

2. Misalignment Compensation
Function: During the operation of construction machinery, shafts connected by the coupling may not always remain perfectly aligned. This can be due to factors such as manufacturing tolerances, thermal expansion, wear over time, or vibrations. The coupling is designed to accommodate different types of misalignments, including angular misalignment (where the shafts are at an angle to each other), parallel misalignment (where the shafts are offset parallel to each other), and axial misalignment (where the shafts move axially relative to each other).
