摘要： A device for clamping a crankshaft in a grinding machine has a rotary face plate which defines a lubricant-filled space and carries two parallel shafts for removable clamping jaws. The jaws can cooperate with a support, which is removably affixed to the face plate, to hold a crankshaft therebetween. The mechanism for pivoting the jaws toward and away from the support has a feed screw which is accessible from the outside of the face plate and extends into the space where it meshes with a nut which can pivot two bell crank levers in opposite directions. The bell crank levers are mounted on the two shafts, and those arms of the levers which must be pivoted by the nut in order to move the respective jaws toward the support carry pistons which deform packages of dished springs when the jaws bear against the crankshaft.

摘要： A grinding machine comprises a grinding shaft which is rotatably mounted on the grinding shaft stock for rotation about a longitudinally extending shaft axis. The grinding machine includes at least one grinding disk fixedly mounted to the shaft and at least one bearing movably disposed between the grinding shaft and the grinding shaft stock for rotatably supporting the grinding shaft. Finally, the grinding machine includes an adjustment means with an adjustable piezoelectric actuator which is disposed between the bearing and the grinding shaft stock. The grinding machine can be used to grind selective regions of a workpiece which is mounted to a workpiece stock so as to define a fixed longitudinally extending workpiece axis. When a changing electrical potential is applied to the adjustment means, a piezoelectric element of the piezoelectric actuator experiences physical deformation thereby allowing the piezoelectric actuator to reposition the bearing until the grinding shaft axis is parallel to the workpiece axis.

摘要： A process for successive grinding of crankpins of crankshaft by a grinder includes clamping the crankshaft at two spaced center journals thereof and rotating the crankshaft around the axis of a crankpin to be ground. To enable the maintenance of highly acurate production tolerances even for small quantities and large crankshafts in an economical manner, only crankpins directly adjacent to the center journals that are clamped are ground. Different clamping positions of the crankshaft are offset axially from one another by the center-to-center distance between two adjacent crankpins of the center journals or a multiple thereof.
摘要翻译：用于通过研磨机连续研磨曲轴的曲柄轴的过程包括将曲轴夹紧在两个间隔开的中心轴颈处，并使曲轴围绕曲轴销的轴线旋转以进行研磨。为了能够以经济的方式维持高度生产公差，即使是小批量和大型曲轴，也只有直接与被夹紧的中心轴颈相邻的曲柄销才被研磨。曲轴的不同的夹紧位置通过中心轴颈的两个相邻的曲柄销之间的中心到中心的距离彼此轴向偏移，或者是其倍数。

摘要： Grinding machine for pins of heavy crankshafts on which the crankshaft is eccentrically mounted in a rotatable clamping arrangement on both sides, where the crankshaft pin to be ground is located in the rotational center of the clamping arrangement and on which the pin can be ground with a grinding head of a cylindrical grinder, with at least one relief arrangement for the crankshaft to supply an eccentrically rotating main bearing with constant, vertically applied force counteracting the dead weight of the crankshaft. The relief arrangement exhibits at least one relief bow for mounting of the main bearing to be supported whose suspension point essentially rotates in a location vertically above the main bearing and synchronously with equal eccentricity as the main bearing.
