摘要： A control module (18) advantageously reduces cost and enhances reliability, design flexibility, ease of assembly, and performance of a flywheel operated hand tool (10). The control module (18) includes a thin film printed circuit with non-contact speed sensing of a flywheel to more accurately set the target speed and control transfer kinetic energy thereof to a fastener, achieving a desired depth regardless of variations in component performance and battery voltage. The printed circuit also includes long service life thin film switches for responding to trigger (30) and safety (34) inputs. Furthermore, the control module (18) responds to a user speed selection (40) and to preset speed selection ranges to reconfigure the controls as appropriate to constraints of a fastener drive assembly and to user preferences.

摘要： Disclosed and taught is a novel drive mechanism for a cyclic operating tool employing an energized flywheel (45) to provide the necessary energy to perform a working cycle. The drive mechanism disclosed is particularly useful in hand tool applications such as a hand held nailing machine. The flywheel (45) may be energized by a corded or battery powered motor. The herein disclosed mechanusm teaches a novel pair of ball ramp cam plates wherein a first pair of ball ramps cause an initial engagement of a clutch (35) with the energized flywheel (45) whereupon rotation of the clutch (36) causes activation of a second pair of ball ramps which affect compression of a spring (72) which acts to increase the pressure applied to the clutch thereby assuring a slip free engagement between the clutch (36) and he flywheel (45) throughout the working cycle of the drive mechanism. Upon completion of the drive mechanisms working cycle, the second pair of ball ramp cam plates further act to disengage the clutch (35) from the flywheel whereby the flywheel (45) may dissipate the unused kinetic energy remaining within the flywheel (45) as the drive mechanism returns to the start position.

The drive mechanism disclosed is particularly useful in hand tool applications such as a hand held nailing machine. The flywheel may be energized by a corded or battery powered motor (42). The herein disclosed mechanism teaches a novel pair of ball ramp cam plates (52, 54, 56, 58) wherein a first pair of ball ramps (56, 58) cause an initial engagement of a clutch with the energized flywheel whereupon rotation of the clutch (35) causes activation of a second pair of ball ramps (56, 58) which affect compression of a spring which acts to increase the pressure applied to the clutch thereby assuring a slip free engagement between the clutch and the flywheel throughout the working cycle of the drive mechanism. Upon completion of the drive mechanisms working cycle, the second pair of ball ramp cam plates further act to disengage the clutch from the flywheel may dissipate the unused kinetic energy remaining within energy remaining within the flywheel as the drive mechanism returns to the start position.
