A processing method for rough cutting hourglass worm on general NC lathe
Journal of Advanced Mechanical Design, Systems and Manufacturing, 2019 The manufacturing method of two spatial-orthogonal rotary axis linkage is usually used to cut hourglass worm. However, the traditional processing method of roughing tooth groove depends on the special machine, specific tool, and its processing efficiency is lower.

A New Method of Inspecting an Hourglass Worm.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1992 A method of inspecting an hourglass worm is newly proposed. The equation expressing the worm tooth surface involves some constants corresponding to the machine setting of the grinding wheel on a worm grinding machine. The constants differ from the design values because of machine setting error.

Establishment of Straight Profile Hourglass Worm under Virtual Reality
Journal of Physics: Conference Series, 2023 Abstract Virtual workpiece is widely used in dynamic simulation and can be imported into the Virtual Gear Measuring Center (VGMC) to be virtually measured. The tooth surface of hourglass worm is complicated, so the dynamic meshing performance is often improved by modification of the tooth surface.

Grinding of high accurate hourglass worm. Trial manufacture of worm grinding device.
Journal of the Japan Society for Precision Engineering, 1988 High accurate worm gears can be effectively used as an angle dividing standard. Wildhaber worm gearing is a kind of hourglass worm gearing. Due to the geometrical simplicity, its worm and worm wheel can be easily finished and accurately measured. This study describes a precision grinding method of the Wildhaber worm.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990 In order to avoid the influence of the displacement of gear axes under load upon tooth contact, the authors propose that a projective group of the surface normals should be concentrated upon the intersection point of the plane perpendicular to the wheel axis and the axis about which the worm axis rotates, displacing its position relative to the wheel ...

Run-on of germline apoptosis promotes gonad senescence in C. elegans [PDF]
, 2016 Aging (senescence) includes causal mechanisms (etiologies) of late-life disease, which remain poorly understood. According to the recently proposed hyperfunction theory, based on the older theory of antagonistic pleiotropy, senescent pathologies can ...
