The planetary gearbox used in factory automation is the important element in order to control the position of each parts. But the studies of these reducers have not been fully implemented enough to design and make the high precision goods. This paper is supposed the various evaluation method of the planetary reducer. And the manufactured products are estimated by each experiments such as the Backlash measurement, Finite Element Analysis, the Accelerated test technique and noise test.

We investigated the coating and curing properties of UV-cationic systems containing different photoinitiators for through and high speed cure by using differential photocalorimetry(Photo-DSC) and fourier-transform infrared spectroscopy(FT-IR). Results of the physical properties showed that the system with iodonium salt type photoinitiator gave slower curing rate but better film properties than those of the systems with sulfonium salt type photoinitiators. Photo-DSC and FTIR/ATR analyses exhibited that the system containing 0.5wt% anthracene photosensitizer and the system conducted on dual curing at 80℃ revealed significantly improved curing rate and crosslink density.
