ABSTRACT
According to the meshing transmission relationship between each part in the transmission process of the F2C-T transmission, the F2C-T transmission is divided into the following four parts:
1. The transmission part of the involute gear The transmission part of the involute gear con-
sists of the input shaft, the key gear, and three planetary gears. And the input shaft and the sun gear are fixedly connected together to form the input gear shaft. And three planetary gears are distributed at angles that are 120 degrees away according to the structure of the planet. 2. Eccentric transmission part
Each eccentric body is composed of a spline shaft, two eccentric shaft necks, and a rotary arm
1 INTRODUCTION
F2C-T transmission is a new pattern with a twostage closed type cycloid transmission device. It exhibits properties, such as high transmission precision, small rotation error, high transmission efficiency, stable transmission, and so on. And so, it has an extremely widespread application prospect in the field of transmission. While studying the F2C-T drive, its structure requires analysis at first. The shape of the components and the transmission relationship between the parts can be grasped. And then, the power loss of the system in the transmission process can be found. The transmission efficiency of F2C-T transmission is calculated. Transmission efficiency is one of the important indexes to evaluate the performance of mechanical transmission devices, and its level also directly affects the research value and development prospects of the device. Therefore, it is of great significance to study the transmission efficiency of F2C-T transmission.
