摘要： This invention pertains to an impact wrench mechanism and a clutch therefor, wherein a motor having an output shaft rotatably drives a carrier member mounted on an axis. Anvil jaw(s) rotatably and coaxially mounted adjacent the carrier member have impact jaw(s) extending radially therefrom. Hammer member(s) having impact jaw(s) for impacting with the anvil jaw(s) is (are) mounted on the carrier member for rotation therewith and for limited linear motion relative thereto in a direction essentially transverse to the axis of rotation to allow the hammer member impact jaw(s) to contact the anvil jaw(s). The line of force of the impact blow has a force component tending to urge the hammer member(s) out of engagement with the anvil jaw(s), but the hammer member(s) have a mass and a mass center location such that linear inertial force is created which prevents motion of the hammer member(s) during the impact blow.
摘要翻译：本发明涉及一种冲击扳手机构及其离合器，其中具有输出轴的马达可旋转地驱动安装在轴上的载体构件。相邻于承载构件可旋转并同轴安装的砧座具有从其径向延伸的冲击颚。具有用于与砧座钳口冲击的冲击颚的锤件（一个或多个）安装在承载构件上以与其一起旋转，并且在基本上横向于旋转轴线的方向上相对于其限制的线性运动，允许锤构件冲击下颚接触砧座。冲击冲击的力线具有倾向于促使锤构件脱离与砧座卡爪接合的力分量，但是锤构件具有质量和质量中心位置，使得线性产生惯性力，其防止冲击冲击期间锤构件的运动。

摘要： This invention pertains to a rotary impact tool and a clutch therefor, wherein a motor drives a carrier cage or member within which is pivotally mounted one or more swinging hollow hammer members. An output shaft extends through the carrier member and through the hollow hammer member and includes forward and reverse impact anvil surfaces. The hammer member is, or members are, mounted to swing in respect to the carrier member as the hammer member(s) rotate(s) with the carrier member, and carries forward and reverse impact jaws on its internal surface. As the clutch is driven in the forward direction by an air motor or the like, the forward impact jaw is moved in and out of the path of the anvil jaw on the output shaft by cam action, and during an impact blow the inertia of the rotating hammer member(s) act automatically to hold the impact jaw in engagement with the anvil jaw.
摘要翻译：本发明涉及一种旋转冲击工具及其离合器，其中马达驱动一个托架架或构件，其中枢转地安装有一个或多个摆动中空锤构件。输出轴延伸穿过承载构件并穿过中空锤构件，并包括前后冲击砧座表面。当锤构件与承载构件一起旋转时，锤构件或构件被安装成相对于承载构件摆动，并且在其内表面上承载正向和反向的冲击爪。当离合器通过气动马达等沿向前方向驱动时，前冲击夹爪通过凸轮作用在输出轴上移动和移出输出轴上的砧座爪的路径，并且在冲击期间的惯性旋转锤构件自动作用以将冲击夹持件保持与砧座卡爪接合。
