The Splined Drive Adapter is to connect a rotating test bench drive shaft with the splined input shaft of a pump during functional testing. It allows torque and rotational motion from the test bench to be transmitted directly to the pump without slippage. The adapter ensures proper engagement between mating splines so rotational power flows smoothly during operation. It enables accurate simulation of operating conditions while testing pump performance.Attributes:• Ensures stable operation during forward rotation testing.• Allows repeated testing without affecting shaft positioning.• Ensures proper spline engagement during pump testing operations.Applications: The Splined Drive Adapter is used between a test bench drive shaft and a pump spline shaft to transmit rotational motion and torque during pump testing and performance evaluation.
