The Impact of a Buyer's Incentives and Organizational Structure on Suppliers' Quality
Journal of Operations Management, Volume 71, Issue 8, Page 1185-1221, December 2025.ABSTRACT Changes in a buyer organization's incentives and structure can have a significant impact on supply chain performance, such as the quality of sourced components. We examine this relationship using data from a unique quasi‐experiment where one of the two plants of a buyer introduced long‐term quality improvement incentives and a more organic ...

Generation of spiral bevel gears with zero kinematical errors and computer aided tooth contact analysis [PDF]
Kinematic errors in spiral bevel gears are a major source of noise and vibrations in transmissions. A method for the generation of Gleason's spiral bevel gears which provides conjugated gear tooth surfaces and an improved bearing contact was developed. A

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1980 Using an inductance type vibrometer for shaft, the displacement of bevel gears is measured on a rectangular-coordinate, and the results are discussed. The results are as follows : The displacements of three directions perpendicularly intersecting each other are influenced by the bending stiffness of gear shaft and the stiffness of bearings.

Research on geometrical characteristics of straight bevel gears with a small shaft angle with a non-generated gear and generated pinion [PDF]
FME Transactions, 2017 Based on the precessional bevel gears with a small shaft angle, a number of drives for oil and gas equipment have been developed. They are characterized by high efficiency (about 0.9) and a small starting torque. Due to multi-pair tooth meshing they have

The Comparison of Straight Tooth Bevel Gear and Spiral Bevel Gear about the Stress of Gear Tooth
Instrumentation and Equipments, 2016 大型的数控龙门加工中心中，卧式主轴头通过一对直齿圆锥齿轮副来作为相交轴的传动部件。其加工中心在高速运转时，直齿圆锥齿轮副会发出大的噪声和冲击，导致加工中心的加工质量和精度下降。为了解决这一问题，提出采用弧齿圆锥轮副代替直齿圆锥齿轮副。基于ANSYS Workbench软件，分析直齿圆锥齿轮副与弧齿圆锥齿轮副的齿跟弯曲应力和齿面接触应力的状况，在此基础上，得出弧齿圆锥齿轮副在传动过程中其轮齿的综合力学性能要优越于直齿圆锥齿轮副相应的轮齿性能。这使得数控龙门加工中心可回转式卧式主轴头在更换前70分贝的噪声降至到60分贝，噪声得到了显著的降低。 In the large CNC gantry machining center, through a pair of straight bevel gear ...

Crack Propagation in Tooth Root: A Comparison Between Pulsator Test and Running Gears
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 12, Page 5181-5194, December 2025.ABSTRACT Tooth root fatigue fracture is a critical gear failure mode in which the tooth root breaks because of the repetition of bending load. The most widely adopted procedure for evaluating root strength is through pulsator testing. However, this test method does not present gears in meshing conditions. When focusing on the limited‐life region of the
