Hollow-Shaft Actuators for Intelligent Automation
IFAC Proceedings Volumes, 1992Abstract For new intelligent automation applications a complex set of requirements exists for electro-mechanical servo actuators. They must exhibit high positioning accuracy and repeatability, high torque capacity and high torsional stiffness, yet also be light, compact and offer a competitve price/performance ratio.

Magnetically Levitated Homopolar Hollow-Shaft Motor
IEEE/ASME Transactions on Mechatronics, 2010This paper describes a novel and compact topology for contactless levitation and rotation of a wide annular rotor through the walls of a sealed process chamber. In the proposed setup, a homopolar magnetic bearing biased by permanent magnets is combined with a high-pole-number segment motor. The paper discusses the functional principle of the motor, and

Novel Integrated Bearingless Hollow-Shaft Drive
Conference Record of the 2006 IEEE Industry Applications Conference Forty-First IAS Annual Meeting, 2006This paper describes a novel and compact design concept for contactless levitation and rotation of a wide annular rotor through the walls of a process chamber. In the proposed set-up, a homopolar magnetic bearing biased by permanent magnets is combined with a high-pole-number segment motor.

Producing hollow drive shafts by rotary compression
Archives of Civil and Mechanical Engineering, 2015The paper presents the numerical and experimental results of producing hollow parts by a new method of rotary compression. First, the most popular methods for producing axisymmetric hollow parts are described. Next, the paper examines the forming of such parts by rotary compression.

Dynamic characteristics of cracked uncertain hollow-shaft
Mechanical Systems and Signal Processing, 2019Abstract Considering the parametric uncertainties, the model of a rotor system with transverse crack is investigated. Polynomial Chaos Expansion is used to describe the uncertainties. The Harmonic Balance method is employed to solve the dynamic equations of cracked uncertain hollow-shaft system.

Hollow Drive Shafts - Innovation by Forming Technology
SAE Technical Paper Series, 2002<div class="htmlview paragraph">Within the scope of the entire car industry, lightweight construction plays an increasingly dominating role in fulfilling requirements from a technological, environmental and economic point of view. This direction is mainly focussed on components that can be produced at optimal weight.

Stability of hollow shafts in torsion
Strength of Materials, 19841. The static load capacity of thin-walled shafts is determined by their loss of stability in torsion. 2. A method is suggested for calculating the stability of hollow smooth shafts and shafts with holes in torsion, with axial forces and centrifugal loads taken into account. 3.

TORSION OF A HOLLOW TAPERED SHAFT
Journal of the American Society for Naval Engineers, 1940The author presents an exact solution of the problem of torsion of a hollow tapered shaft. He attains an order of accuracy hardly required for engineering purposes. The solution is presented as of possible academic interest to some members.

Fatigue failure of a hollow power transmission shaft
Engineering Failure Analysis, 2002A micro/hairline crack was noticed on a low speed, hollow shaft of a single stage helical gearbox during service. Though this had not resulted in a catastrophic failure, the shaft was withdrawn from service because of leakage of oil. Subsequent investigation revealed that the crack had initiated by fatigue at one of the keyway edges and progressed ...

Elastoplastic torsion of hollow FGM circular shaft
2015In many cases, a torsional shaft may be a thick-walled radially inhomogeneous cylindrical object. The hollow shafts made of functionally graded materials (FGMs) are such kind of compositions which were studied in this paper. Cylindrical FG shafts are composed of ceramic and metallic parts with power function distribution across the radial direction ...
