摘要: A drill chuck has a chuck body, a holder body, and an outer sleeve surrounding the bodies, with jaws between them. A ring of teeth on one of the bodies can be engaged by a pawl angularly fixed on the other of the bodies. When engaged, the pawl and the array of teeth allow rotate relative to the chuck body in a tightening direction but not in a loosening direction. Respective interengaging stops on the other body and on the outer sleeve limit relative angular movement of the outer sleeve on the other body between a pair of angularly offset end positions. An inner control sleeve has a cam formation engageable with the pawl in only one of the end positions to hold the pawl in the freeing position. The pawl is biased by a spring in the other end position into the locking position.

摘要: A drill chuck has a chuck body, a holder body, and a front sleeve surrounding the bodies, with jaws between them. A ring of teeth on one of the bodies can be engaged by a pawl angularly fixed on the other of the bodies. When engaged, the pawl and the array of teeth allow rotate relative to the chuck body in a tightening direction but not in a loosening direction. Respective interengaging stops on the other body and on the front sleeve limit relative angular movement of the front sleeve on the other body between a pair of angularly offset end positions. A back control sleeve has a cam formation engageable with the pawl in only one of the end positions to hold the pawl in the freeing position. The pawl is biased by a spring in the other end position into the locking position.
摘要翻译: 钻夹头具有卡盘主体,保持器主体和围绕主体的前套筒,其间具有夹爪。 其中一个主体上的一个齿环可以通过角度固定在另一个主体上的爪来啮合。 当接合时,棘爪和齿排允许在紧固方向上相对于卡盘体旋转,而不是在松动方向上旋转。 在另一身体和前套筒上的相互接合止挡限制了在一对角度偏移的端部位置之间的另一个主体上的前套管的相对角度运动。 背部控制套筒具有凸轮形成部件,该凸轮部件仅在一个端部位置处与棘爪接合,以将棘爪保持在释放位置。 棘爪被另一端位置的弹簧偏压到锁定位置。

摘要: A valve positioning device capable of comparing the travel position of an output shaft of a diaphragm actuator or cylinder with the pressure level of a pneumatic input signal and further being capable of manipulating the pressure of a separate air signal piped to said diaphragm actuator or cylinder in order to correct any imbalance between said stem position and a given pneumatic signal level; wherein said valve positioning device is further capable of varying its dynamic response by built in adjustment means.
