An envelope shaping method for huge straight bevel gear [PDF]
An envelope shaping method of machining huge straight bevel gear is proposed in this paper. This method can achieve higher machining precision and efficiency. Firstly, the geometric characteristic of the tooth surface is analyzed. Then an envelope shaping principle is given. Based on this principle, the mathematical model of machine motion is built. In

Molecular Photogearing for Controlling Rotary Motion at the Nanoscale
Molecular gears capable of controlling and transmitting rotary motion at the nanoscale are indispensable for the construction of artificial molecular machines. In this concept, we discuss how molecular photogears featuring a propeller‐shaped motif attached to a light‐driven molecular motor offer new possibilities to perform these tasks with better ...

Policy Spandrels: How Design Decisions Can Open Up Spaces for Unintended Policy Change
ABSTRACT This article introduces the concept of policy spandrels to make sense of public policies producing second‐order effects that are unintentional from the perspective of policy design and yet are fraught with consequences. By analogy with architectural spandrels—leftover spaces that can be used for unforeseen purposes—policy change can be enabled

PROFILE MODIFICATION INFLUENCE ON THE CONTACT RATIO FOR STRAIGHT BEVEL GEAR
Bevel gear, as octoidal gear, is not accurate involute. As a result, unlike involute cylindrical gear, bevel gear is accomplished by using profile which are not modification or profile with zero modification.

Dynamic Behavior of Straight Bevel Gears of Gleason Type
Dynamic behavior of straight bevel gears of Gleason type was investigated by measuring the dynamic load, circumferential, radial and axial vibration accelerations of gears and noise under different running conditions. It was found that the root stress ratios of maximum dynamic root stress to static one in the toe, middle and heel of a straight bevel ...

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.
