| Careful adjustment of the shaft bevel gear and bevel gear is essential to ensure that the final drive gear set gives long service and runs silently. During manufacture the bevel gear and shaft bevel gear are therefore matched and checked on testing machines to ensure correct mesh pattern and silent running. The position for quietest running is obtained by moving the shaft bevel gear axially and, at the same time, maintaining the backlash within the specified tolerance. If required, the shaft bevel gear and bevel gear (final drive gear set) must always be renewed together. |
