WELL SERVICING PUMP SYSTEM WITH DRIVELINE ASSEMBLY FOR HYDRAULIC FRACTURING SYSTEM

Abstract: a driveline assembly for use with a well-servicing pump system is disclosed. the driveline assembly comprises a stub shaft attachable to one of a pump or a motor, a flange shaft attachable to the other of the pump or the motor, and a coupling assembly comprising a drive-transfer cylinder and a spring-loaded locking sleeve. in a drivingly-engaged position, rotary drive motion of the motor is transferred to the pump. in an unlocked position, the locking sleeve allows the drive-transfer cylinder to move axially from the drivingly-engaged position where the drive-transfer cylinder connects and transfers rotary drive between the flange shaft and the stub shaft to the drivingly-disengaged position where the drive-transfer sleeve disconnects and allows relative rotation between the flange shaft and the stub shaft. in a locked position, the locking sleeve locks the drive-transfer cylinder in one of either the drivingly-engaged position or the drivingly-disengaged position.
