    摘要： A gear machining device is provided which can machine an accurate gear by a cutting process by synchronously rotating a machining tool and a workpiece at a high speed. A machining tool includes roughing cutting teeth for roughing bottom lands and right and left side faces of teeth of a gear, right side face finishing cutting teeth for finishing the right side faces of the teeth, and left side face finishing cutting teeth for finishing the left side faces of the teeth. The cutting teeth thus cut different parts of the teeth of the gear. This can reduce cutting resistance and suppress self-vibration during the cutting process, thereby improving tooth trace accuracy of the gear.

    摘要： For machining the tooth flanks of a hardened workpiece having pre-formed teeth two cutting blades or plates are secured to a cutting blade or plate holder. The cutting blades or plates are provided with a base member or backing formed of a hard metal and a cover layer sintered thereon which is formed of cubic boron nitride. Each cutting blade forms a cutting surface and a clearance surface. Each individual cutting blade or plate is arranged at the cutting blade or plate holder in relation to the direction of the intended cutting movement such that the surface of the cover layer forms the clearance surface and an end face or surface of the cover layer is located in the cutting surface. Consequently, there is achieved the result that the cutting surface can be reground in the same manner as tools which, for example, are made of hardened steel and which are not provided with a cover layer.

    摘要： An apparatus for regulating the lapping pressure during the lapping of two bevel gears at a lapping machine comprising a device for driving one of the bevel gears and for braking the other bevel gear. A control mechanism for adjusting the desired lapping pressure. A differential pressure transmitter is operatively connected with the control mechanism, said differential pressure transmitter serving to measure the liquid-pressure differential brought about by the bearing load in a hydrostatic bearing of one bevel gear in order to regulate the lapping pressure as a function of the bearing load at the aforesaid drive- and braking device.
