The paper analyzed the motion principle of an end-face lapping machine for an optical fibre conneetor,and deduced the expressions for the workpiece′s motion path in relation to its lapping plate and the motion path vise versa,both of which,as shown by Eqs(5) and(6) in the full paper,are trochoid.

The wave model was generated by using real frequency spectrum of ocean wave to control the 3-D trochoids.

The experimental results showed that high quality of cavity surface can be obtained by using appropriate technologic parameter and trochoidal milling mode with micro-end mill cutter.

In order to improve the mechanical performance and transmission efficiency of the traditional pulsed mechanical continuously-variable transmission(CVT),a novel pulsed CVT is proposed according to the linear characteristic of hypocycloid at specific parameters and by combining the planet gear transmission mechanism with the crank slide block mechanism.

Based on the causing principle of hypocycloid ,this paper discusses the track of geometric elements in moving circle plain under different conditions, theapplication of hypocycloid in mechanical engineering is also briefly demonstrated.

The working principle and structural design of a new hypocycloid energy transformation mechanism is introduced,and the dynamic model of the mechanism is established using the Euler-Lagrange approach based on energy.

This paper discusses the formation and properties of the inner cycloid and the principle of the tritubercular cycloidal pump is illustrated.

The text introduces the two choices of inner gear profile curve of the rolling gear drive and the theoretical reasons of the equidistance curve of inner cycloid and the close an; curve.
