摘要： The stability of an animal joint, especially a knee, is assessed with an arrangement having track arranged about perpendicular to the axis of the distal portion; a cart slidably engaged to the track; a fork positioned on the cart; a support adapted to receive the distal linear portion, the support connected to the fork; a lever arm connected to the support, the lever arm positioned to rotate the support about the axis of the distal portion; and at least one instrumented handle, the instrumented handle detachably engages at least one of the cart and the lever arm. In some embodiments, the fork can rotate freely on the cart. Additionally, in various embodiments, the cart may be selectively locked at a position along the length of the track. In various embodiments, the arrangement further comprises: a bracket rigidly attached to the distal portion and positioned between the support and the joint; and the at least one instrumented handle detachably engages the bracket.

摘要： A dressing roll unit is supported on a nonrotating shaft clamped and maintained as a "fixed end" beam, thereby restrained against axial movement and deflection. The shaft is formed with spaced-apart bearing points, wherein wedge-shaped relief sectors are formed about the shaft at the bearing points, and a roll body is maintained about the bearing points with an annular clearance. Rotation of the dressing roll body and roll thereby forms high pressure hydrodynamic wedges of oil at the relief sectors and annular clearances, to create an extremely rigid roll mounting unit, without the need for pivoting bearing parts.
摘要翻译： 修整辊单元支撑在作为“固定端”梁夹持并保持的非旋转轴上，从而抑制轴向运动和偏转。 轴形成有间隔开的轴承点，其中在轴承点处围绕轴形成楔形浮雕扇区，并且辊体围绕具有环形间隙的轴承点保持。 修整辊体和辊的旋转从而在浮雕扇区和环形间隙处形成高压油压楔形油，以形成非常刚性的辊安装单元，而不需要枢转轴承部件。

摘要： A spindle is rotatably mounted within a housing on spaced-apart antifriction bearings. The inner races of the bearings are held solidly against shoulder portions of the spindle and the outer race of the front bearing is mounted against a shoulder in the housing. The outer race of the rear bearing is supported in a circular diaphragm concentric with the spindle axis, which may be flexed along the axis to load the bearings against one another. A hydraulic chamber is formed against the diaphragm to load the diaphragm at preselected intervals, and a stop plate is provided in the housing to limit movement of the outer race is a distance corresponding to a maximum preload in the bearings. When the stop plate is contacted, hydraulic pressure may be greatly increased to further load the diaphragm and its corresponding outer race solidly against the stop plate without further increasing the preload in the bearing set, providing a high holding force resistant to spindle pull out.
摘要翻译： 主轴可旋转地安装在壳体内的间隔开的减摩轴承上。 轴承的内圈固定地固定在主轴的肩部上，而前轴承的外圈安装在壳体的肩部上。 后轴承的外圈被支撑在与主轴轴线同心的圆形隔膜中，该轴承可以沿轴线弯曲以将轴承彼此加载。 液压室形成为抵靠隔膜以预选的间隔装载隔膜，并且在壳体中设置挡板以限制外座圈的移动距离对应于轴承中的最大预载。 当挡板接触时，可以大大提高液压压力，以进一步将隔膜及其对应的外圈固定地抵靠止动板，而不会进一步增加轴承组中的预载荷，从而提供抵抗主轴拉出的高保持力。

摘要： Grinding and regulating wheels are carried on opposed feed slides on a machine base. A workrest is fixed to the base between the opposed wheels. Wheel dressers are mounted to cross-slides on the base, behind the wheels, independent of the feed slides. CNC dressing occurs through combined transverse motions of feed slide (with wheel) and cross slide (with dresser).
