摘要： Disclosed and taught is a novel drive mechanism for a cyclic operating tool employing an energized flywheel 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 may be energized by a corded or battery powered motor. The herein disclosed mechanism teaches a novel pair of ball ramp cam plates wherein a first pair of ball ramps cause an initial engagement of a clutch with the energized flywheel whereupon rotation of the clutch causes activation of a second pair of ball ramps 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 he 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 whereby the flywheel may dissipate the unused kinetic energy remaining within the flywheel as the drive mechanism returns to the start position.
摘要翻译： 公开和教导的是用于循环操作工具的新颖的驱动机构，其采用赋能飞轮来提供必要的能量来执行工作循环。 所公开的驱动机构在诸如手持打钉机的手工工具应用中特别有用。 飞轮可以由有线或电池供电的电动机通电。 本文公开的机构教导了一对新的一对滚珠坡道凸轮板，其中第一对滚珠坡道引起离合器与通电飞轮的初始接合，由此离合器的旋转引起第二对滚珠坡道的启动，这影响了压缩 弹簧用于增加施加到离合器的压力，从而确保在驱动机构的整个工作循环期间离合器和他的飞轮之间的无滑动接合。 在驱动机构工作循环完成时，第二对滚珠坡道凸轮板进一步用于使离合器与飞轮脱离接合，由此当驱动机构返回到起始位置时，飞轮可以消散剩余在飞轮内的未动能。
