研究出一种殿面驱动用旋转作动器。利用逆滚动螺旋机构将油缸的直线运动直接转换为旋转运动。研究表明，这种新作动器与现有作动器比较，具有输出矩大，直径小，重量轻，标准化通用化的优点。

针对现存的各种V带不足之处，提出了一种复合V带的新结构，提出了设计计算方法，制造出了样品，并对样品的一些性能和寿命进行了试验。

多年研究表明，利用现有的切削理论，已经无法再成十倍的提高切削速虎一种新的超高速铣削理论被提出，它的思想是：一方面利用挤压变形和摩擦，提高工件切削区的温度，使工件的强度和硬度显著下降另一方面，设法保持刀具的温度在300℃以下，使硬度保持不变；从而实现了刀具硬度与工件硬度比的大量增加，实现了μc=8500m/min超高速铣削。本理论已经生产验征，表明本理论的正确性。

The design of a novel transmission for reduction is reported in this paper. The transmission is based on the layout of triangle mechanisms, for it is intended to reduce speed. Two course of the reduction, that we term Rotating-Straight-Rotating (R-S-R), are described here, namely, first rotation movement is transformed to straight movement and then straight movement is transformed to rotating movement again though two triangle screw structure. The reducer can be applied to the purpose of the large-scale reducing speed.

In this papers, a new type of Magnetorheological Fluids continuously variable transmission (MRFCVT) with V-shape working gap and Self-pressurized structure was given, introduced the work principle and structure, also deduced the dynamical equation and Self- pressurized formula of MRFCVT, did some simulative caculation about virtual prototype in two-dimension static magnetic field using finit element method, an explicit conclusion was drawn that this new type of MRFCVT which was reinforced by the self-pressurized structure can be applied in power transmission domain.MRF, Self-pressurized, Simulation, CVT
