摘要： Counterbalanced mechanism for a jaw chuck. There is provided for an otherwise conventional multi-jaw chuck suitable mechanism for independently balancing each said jaw. In a preferred embodiment, a pin is pivotally fixed at one of its ends into each master jaw, pivoted to the chuck body intermediate its ends and pivotally related at its other end to a radially movable counterbalancing mass. Each said mass and jaw are so related to the lever pin upon which they operate that they create balancing moments when the centrifugal force acting on each is equal and, due to the geometry of the apparatus, said moments remain sufficiently close to equal at any speed of operation of the chuck that a substantial balancing of the parts is obtained. Thus, whether the chuck is inside gripping or outside gripping, it can be properly adjusted in a normal manner at a standstill and the pressure of the chuck onto the workpiece will not materially change within the range of any normal operating speed.

摘要： Self-ejecting chuck key for a gear chuck. A coil spring is arranged on the key of a gear chuck around the shank thereof and between means for holding same in position. Said spring includes a number of turns enlarged to clear the bevel gear of the key and preferably extends beyond said gear to a point between the small end of said gear and the end of the key. Said spring is made sufficiently soft that it can bear on both the body and the jaw nut of the chuck simultaneously without interfering with the effective and convenient operation of the key.

摘要： A jaw chuck provided with an inner sleevelike housing which, at its forward end, is provided with radially extending T-shaped slots which slidably accommodate the jaw carriers. The inner housing is totally surrounded and fixedly connected to an outer sleevelike housing which overlaps the outer ends of the slots. A push-type activator is disposed adjacent the rearward end of the inner housing and is axially slidable relative thereto. This activator includes wedges which project axially forwardly and are slidably and wedgably engaged with the jaw carriers for effecting radial displacement thereof. The wedges have the outer peripheries thereof axially slidably supported on the inner periphery of the outer housing.

摘要： A jaw chuck construction having an inner sleevelike body containing a plurality of radial guide grooves in which are slidably disposed jaw carriers. An actuator device is axially slidably supported within the inner body and has axially projecting wedges which cooperate with mating wedges formed on the jaw carriers for camming same radially toward or away from a workpiece. The axially projecting wedges slidably project into central slots formed in the individual jaw carriers for engaging the latter substantially centrally of the jaw carrier to minimize tilting and off-center loading of the jaw carriers. The inner body and the jaw carriers are confined by an outer sleevelike body which snugly embraces the inner body and slidably engages the outer radial surfaces of the axially projecting wedges, whereby centrifugal forces imposed on the jaw carriers are transmitted directly to the axially projecting wedges and then imposed directly on the surrounding outer body so that the centrifugal forces do not appreciably affect or reduce the gripping force between the jaws and the workpiece.

摘要翻译： 一种夹爪卡盘结构，其具有包含多个径向引导槽的内部套筒体，其中可滑动地设置有夹爪承载件。 致动器装置轴向可滑动地支撑在内体内并且具有轴向突出的楔形件，其与形成在钳口支架上的配合楔配合，以径向朝向或远离工件进行凸轮转动。 轴向突出的楔形物可滑动地突出到形成在单个颚板载体中的中心狭槽中，用于与后者基本上接合颚板载体的中心，以最小化颚骨架的倾斜和偏心加载。 内部主体和下颚托架由外部套筒体限定，该外部套筒体紧密地包围内部主体并且可滑动地接合轴向突出的楔形件的外部径向表面，由此施加在夹爪支架上的离心力直接传递到轴向突出的楔形件， 然后直接施加在周围的外部体上，使得离心力不会明显地影响或减小夹爪和工件之间的夹持力。
