Pinion Preload Setting & Checking

The Pinion Preload setting & checking system held by spring balancer at the assembly line, the operator engages the fixture with the housing by guiding in the dowels and performs testing.

• The Gear-Box is received at the backlash station after installing the crown gear using master shim.
• The operator measures the backlash of the Ring gear and enters the value in the software.
• The Final preload checking fixture is held by spring balancer at the assembly line, the operator engages the fixture with the housing by guiding in the dowels.
• The operator starts the Run. The Preload value is measured by the torque cell.
• The Operator enters this value in the software. The software using predictive and mathematical algorithm calculates the Shim required for setting the Backlash between 0.1-0.3mm and     final preload between1.84-2.74 Nm.
• The values for increasing or decreasing the shims on LH and RH side is displayed on the screen.
• The operator uses these shims and re-assembles again.
• The process is finished by checking the final preload and backlash.
