🔧 Gear Flange – Tata 1212 (Serrated Type)
📌 Overview
A gear flange (serrated) for the Tata 1212 truck is a drivetrain coupling component used in the transmission output / propeller shaft / differential connection area. This flange features a serrated (or cross-serrated) contact face that ensures positive mechanical engagement with the mating shaft yoke or companion flange. It is designed for high torque transmission and vibration resistance in medium-duty commercial truck applications like the Tata 1212 series.
Tata 1212 trucks are medium-capacity cargo vehicles with a 3.3 L diesel engine, manual gearbox (GBS-40), and robust drivetrain suited for hauling loads around 12 tons GVW.
⚙️ Function & Features
✔ Serrated Contact Surface
The serrated (toothed) flange face provides a stronger frictional bond between the flange and the corresponding yoke or companion flange.
This reduces micro-slip under load and increases dependable torque transfer through the drivetrain.
✔ Drivetrain Coupling Role
Connects the gearbox output to the propeller shaft or the propeller shaft to differential in the truck’s driveline.
Ensures that rotational power from the gearbox is smoothly delivered to the rear axle without loss or backlash.
✔ Construction & Material
Typically forged steel or machined alloy steel designed to handle heavy loads, shock loading, and vibration stresses typical of commercial truck use.
✔ Engineered for Heavy-Duty Use
Matched with Tata truck powertrains like the 1212 series that produce robust torque outputs, ensuring drivetrain components work reliably over long life cycles
