  3. Hirth joint - Wikipedia

    en.wikipedia.org/wiki/Hirth_joint

    Hirth joint made from anodized aluminum to show the meshing of the teeth Hirth joint (disassembled) between the semi-axles of a Campagnolo Ultra-Torque crankset. Face spline joints consist of a ring of radial splines or teeth milled or ground into the end faces of two rotary components such as a drive shaft and the hub of a wheel.

  4. Spline (mechanical) - Wikipedia

    en.wikipedia.org/wiki/Spline_(mechanical)

    A spline is a ridge or tooth [1] [2] [3] on a drive shaft that matches with a groove in a mating piece and transfers torque to it, maintaining the angular correspondence between them. For instance, a gear mounted on a shaft might use a male spline on the shaft that matches the female spline on the gear.

    Shaft angle. A shaft angle is the angle between the axes of two non-parallel gear shafts. In a pair of crossed helical gears, the shaft angle lies between the oppositely rotating portions of two shafts. This applies also in the case of worm gearing. In bevel gears, the shaft angle is the sum of the two

  6. Linear-motion bearing - Wikipedia

    en.wikipedia.org/wiki/Linear-motion_bearing

    Ball splines (ball spline bearings) are a special type of linear motion bearing that are used to provide nearly frictionless linear motion while allowing the member to transmit torque simultaneously. There are grooves ground along the length of the shaft (thus forming splines ) for the ball bearings to run inside.

  7. Steel grades - Wikipedia

    en.wikipedia.org/wiki/Steel_grades

    In addition to the above category codes there are symbols that can be added to the grade code to identify any additional compositional requirements, delivery conditions, mechanical properties, &c. These values depend solely on the type/application code given in the first part of the code and are so numerous as to be impossible to indicate here.

  8. Strain wave gearing - Wikipedia

    en.wikipedia.org/wiki/Strain_Wave_Gearing

    For example, if there are 202 teeth on the circular spline and 200 on the flex spline, the reduction ratio is (200 − 202)/200 = −0.01 Thus the flex spline spins at 1/100 the speed of the wave generator plug and in the opposite direction. Different reduction ratios are set by changing the number of teeth.

  9. Ball screw - Wikipedia

    en.wikipedia.org/wiki/Ball_screw

    The second principal curvature is simply = for the screw shaft groove and = for the nut groove, where and are, respectively, the conformity factors of the groove profiles of the screw shaft and nut. These formulations do not take into account the shape of the groove profiles and the presence of the helix angle: more recent publications found ...
