摘要： A collet chuck 1 having a chuck body 3, a collet 11 disposed in the body 3, a nose ring 23 for radially compressing the collet 11, and a locknut 30 for axially moving the nose ring 23 into compressive engagement with the collet 11 is provided with a bearing assembly 45 disposed between the nose ring 23 and the collet 11 which loads compressive forces in a direction which is advantageously parallel to the axis of rotation A of the chuck. Both the locknut 30 and the nose ring 23 include flange portions 27, 43 that confront each other with opposing surfaces 47, 49 that are complementary in shape to the spherical profile of the ball bearings 50 and which traverse a line L parallel to the axis of rotation A of the chuck. The collet chuck 1 further includes O-rings 61, 65 disposed between the nose ring 23 and the locknut 30both in front of and behind the ball bearings 50 for sealing the bearing assembly 45 against dust and debris and retaining lubricant. Finally, the portion of the nose ring 23 which wedgingly engages the collet 11 to compress it inwardly is undercut with a groove 72 in order to enhance the compliance between the nose ring 23 and the collet 11, thus providing a more uniform radial compressive force around the collet 11 which in turn results in improved gripping characteristics.

摘要： La invencion es una boquilla de quijadas convergentes que satisface todos los criterios antes mencionados al tiempo que evita las desventajas asociadas con la tecnología anterior. La boquilla de quijadas convergentes de la invencion generalmente comprende un collar dispuesto en un bastidor giratorio, un anillo de oreja dispuesto alrededor del collar y tiene una porcion de leva para comprimir de manera radial la orilla externa elástica, una contratuerca dispuesta alrededor y acoplada de forma roscada al bastidor de la boquilla que tiene una porcion de pestaña que confronta una porcion de pestaña del anillo de oreja para aplicar fuerzas de compresion allí en una direccion que es paralela al eje de rotacion del bastidor de la boquilla. Algo muy importante, la boquilla de quijadas convergentes comprende además un ensamble de cojinetes para transmitir la fuerza de compresion paralela entre las porciones de pestaña confrontantes del anillo de oreja y la contratuerca. Con este fin, el ensamble de cojinetes incluye ranuras opuestas en las pestañas confrontantes de la contratuerca y el anillo de oreja, respectivamente, y una pluralidad de cojinetes de bolas dispuestos entre estas ranuras donde cada ranura tiene, en seccion transversal, una porcion arqueada complementaria en forma para los cojinetes de bolas que atraviesa una línea paralela al eje de rotacion del bastidor de la boquilla, y un anillo elástico (de resorte) de diseño balanceado. En la incorporacion preferida, las porciones arqueadas de las ranuras definen a todas las superficies opuestas completas de las porciones de pestaña opuestas del anillo de oreja y contratuerca. Adicionalmente, la porcion arqueada de cada ranura de preferencia circunscribe por lo menos 100o alrededor de la circunferencia de los cojinetes de bolas. La forma complementaria de las porciones arqueadas con respecto a la superficie de los cojinetes de bolas, acoplada con su extension de 100o, provoca las fuerzas compresivas que van a transmitirse desde la contratuerca hacia el anillo de oreja mediante el amplio contacto de superficie a superficie entre los cojinetes de bolas y las superficies de las ranuras. De preferencia, por lo menos 10o de la extension de 100o de cada una de las ranuras está dispuesto en un lado de un línea paralela al eje de rotacion del bastidor de la boquilla para asegurar que esta fuerzas de compresion se transmitirán axialmente en forma paralela. Para asegurar que el anillo de oreja aplicará uniformemente una fuerza radial de compresion alrededor de la superficie seguidora en el collar, se proporciona una ranura de deformacion por debajo de la superficie de leva del anillo de oreja para hacer que la superficie de leva sea más fácilmente conformable para la superficie seguidora del collar. La provision de tal ranura crea un elemento de leva más delgado con forma de borde de anillo de oreja que tiene un extremo libre relativamente elástico. Para evitar que el polvo y los escombros entren el ensamble de cojinetes y retener el lubricante, un par de anillos-O están dispuestos entre las superficies adyacentes del anillo de oreja y la contratuerca ambos en frente de y por detrás de los cojinetes de bolas. Los anillos-O están formados de preferencia de un elastomero que tiene una alta resistencia a la abrasion y baja friccion, tal como el poliuretano, para características de largo uso. Finalmente, debido a que las porciones de tipo pestañas del anillo de oreja y la contratuerca están dimensionadas de tal forma que el anillo de oreja es instalable de forma libre en la contratuerca sin interferencia mecánica, el ensamble de cojinete de la invencion puede armarse rápidamente al asentar el primero de los dos anillos-O en una ranura en la contratuerca y luego colocar los cojinetes de bolas en su ranura respectivamente en la contratuerca, asentando el segundo de los dos anillos-O, colocando el anillo de oreja en su lugar sobre los cojinetes de bolas y luego instalando un anillo elástico sobre el anillo de oreja con el fin de asegurarlo en su lugar sobre los cojinetes de bolas. La contratuerca puede entonces atornillarse sobre el extremo del cuerpo de la boquilla roscada.

摘要： An collet and lock nut assembly includes a collet for receiving a cutting tool shank and a lock nut for creating a gripping force between the collet and the shank. The collet has a nose portion and a body portion separated by an annular groove. The lock nut has a plurality of retention tabs and a corresponding number of clear portions. The collet and lock nut assembly can be easily assembled by inserting at least one retention tab within the groove of the collet, and then applying pressure to the collet such that the remaining retention tabs of the lock nut are received within the groove of the collet to place the assembly in a locked position. The collet and cutting tool shank can be drawn from the tool holder by applying rotational torque to the lock nut. The collet is easily removed from the lock nut by applying pressure in any circumferential, lateral direction against the collet.
