Study on lubricant of open gear and its applications;

Inquiring into Open Gear Lubrication of Rotary Kiln;

Strength analysis of open gear for winch sluicegate hoist based on reliability theory;

In respect of the main power loss of the exposed gears,a designing theoryand method was offered to design stub tooth gears accoding to their contact intensity.

Diagnosis of the abnormities of the exposed gear of balling drum based on Fourier analysis was made,and the result indicates that,the outcome of Fourier analysis is definitely the same as the actual running status.
