Abstract: The essence of the multidisciplinary collaborative design problem (MCDP) is the coordination of the design variables among multiple disciplines on the basis of the all constraints of all disciplines. There exist some problems such as the early detection of design conflicts and the determination of the consistency domains of the design variables, etc. The resolving of these problems can help designers avoid bad decision-making, reduce the design iteration and improve the design efficiency. Aiming at the problems, this paper proposes a constraint-net model to describe and manage all the design variables and constrains of all disciplines, discusses the reformulating method of the MCDP to improve computation efficiency, and develops the interval propagation algorithm to determine the consistency domains of the design variables, etc. A gear drive is taken as an example to illustrate the effectiveness of the proposed method.

Abstract: Geometric design procedures for the cycloidal drive with ceramic ball meshing elements were introduced. Using the theory of conjugate surfaces, the equations of meshing of the cycloid drive and the cycloid raceway profiles were derived. Design examples were presented to demonstrate the design procedure and feasibility. The ceramic balls were used as the meshing elements. Prototype of this research was made and tested with satisfying results. The results of this work are suitable for computeraided design and manufacture of industrial applications.

Abstract: This paper presents geometric design procedures for a new type of roller drive. Here, the pinion has two circularly arrayed cylindrical teeth instead of one circularly arrayed. This proposal is based on coordinate transformation and envelope theory, from which the epicycloid profiles are obtained. The centers of the cylindrical teeth of the pinion are determined by equidistant offset a distance 3 ρ (pinion-tooth radius). The real pinion profiles are the equidistant curve of the epicycloid profiles. Two examples are presented to demonstrate that this approach is feasible.
