FEA-optimized lightweight hollow shafts for the transmission

ATZ worldwide, 2009
When it comes to transmissions, considerable weight savings may be made by using hollow transmission shafts. Hirschvogel achieved success in transferring the same high loads in spite of less material use. These forged light- weight shafts may be used both in manual transmissions as well as in axle drives and transfer gearboxes of passenger cars or ...

Scaling of magnetically levitated homopolar hollow-shaft machines

2013 IEEE 10th International Conference on Power Electronics and Drive Systems (PEDS), 2013
In this paper, we analyze scaling issues that arise when the size of a magnetically levitated hollow-shaft machine is varied, but the output power is kept constant. Reducing the size by a factor of two leads to a required increase in speed by a factor of about three.

Torsional Vibrations of a Nonprismatic Hollow Shaft

Journal of Vibration and Acoustics, 1989
Propagation of torsional waves in elastic homogeneous non-prismatic hollow shafts is investigated. Three different types of end conditions are considered: both ends fixed, both ends free, and one free—one fixed end. Design charts are presented to determine the natural frequency of a nonprismatic hollow shaft upon specifying its geometric profile, end ...

VIBRATION OF STRAIGHT–CURVED–STRAIGHT HOLLOW SHAFTS

Journal of Sound and Vibration, 2000
Abstract This work presents the governing equations for both the in-plane motion and out-of-plane motion of a curved hollow shaft. Two types of shaft structures, which are a curved hollow shaft and a straight–curved–straight hollow shaft, are considered.

New warm forming processes to produce hollow shafts

Journal of Materials Processing Technology, 2001
Abstract In order to maintain their competitiveness, the producers constantly have to reduce their costs and to improve the quality of their products. The trend towards lightweight construction in vehicle manufacturing results in an increased use of hollow shafts in vehicle gear boxes.

Analytical Modeling of a Material Efficient Hollow Shaft Design

Advanced Science, Engineering and Medicine, 2020
This paper discusses the optimal distribution of material across the cross-section of a shaft under pure uniform torsional loads such that the factor of safety and thereby the shear stresses generated at any point in the cross-section remain largely the same irrespective of their radial distance from the centre of the shaft. An analytical mathematical

Manufacturing of hollow transmission shafts via bulk-metal forging

Journal of Materials Processing Technology, 1997
Abstract More and more hollow transmission shafts are used in all vehicle gears as a result of the demand of light components. Different methods of bulk-metal forging are shown partially in combination with joining and machining processes. They will be discussed with reference to shaping, tolerances and economical aspects.

Grinding Characteristics of Carbon Fiber Epoxy Composite Hollow Shafts

Journal of Composite Materials, 2000
Since carbon fiber epoxy composite materials have excellent structural properties due to their high specific strength, high modulus, high damping and low thermal expansion, composite hollow shafts have been widely used for power transmission shafts for motor vehicles, spindles for machine tools, and rollers for thin film processing.

Analysis of buckling of hollow laminated composite drive shafts

Composites Science and Technology, 1995
Abstract Laminated composite, circular cylindrical hollow shafts are used extensively as primary load-carrying structures in many applications under various loading configurations. Advanced composite materials also seem ideally suited for long, power drive-shaft applications.

Critical speed analysis of laminated composite, hollow drive shafts

Composites Engineering, 1993
Abstract A theoretical analysis is presented for determining the critical speeds of a rotating circular cylindrical hollow shaft with layers of arbitrarily laminated composite materials by means of the thin-and thick-shell theories. The theory used is the dynamic analog of the Sanders best first approximation shell theory.
