📌 What is a Gear Coupling?
A gear coupling is a mechanical torque‑transmitting joint that connects two rotating shafts (for example, the driveshaft to another shaft) and allows the drivetrain to transfer power smoothly even when the connected shafts are slightly misaligned. It uses mating gear teeth on the hubs and sleeves to transmit torque efficiently and is common in heavy‑duty vehicle drivetrains that require high torque capacity.
In truck driveline applications (such as Eicher), gear couplings are used to:
Join the propeller shaft to companion flanges or intermediate shaft hubs
Transmit torque between non‑collinear shafts with some permissible misalignment
Provide a stronger mechanical connection than a simple sleeve or smooth adapter
Improve drivetrain durability and reduce vibration under load.
🔩 Typical Gear Coupling Types / Parts You Might Use
Here are some gear coupling products that serve the general purpose of torque transmission between shafts and can be used in automotive or industrial driveline setups (note: they may not be Eicher‑OEM specific but fit similar coupling functions):
