抄録

It is essential to measure the forces at the threshing teeth or the screw on a threshing cylinder and to understand its effect on the cylinder shaft torque and its variation towards the axial direction in order to reexamine the specification of the cylinder for the purpose of reduction of required power. The threshing performance should be also taken into consideration. The prediction of the torque was made an attempt in this part of the paper. This is the prediction of the torque from the force of blow in the threshing teeth and the tangential force of edge in the screw which were measured by the load detector formerly reported to understand the effect of its torque on the cylinder shaft torque. This part also describes to seize the threshing condition under the present specification by means of inspecting the distribution of grain which is threshed and pass through the concave. A testing facility which had the screw type thresher was developed. The specification of this threshing cylinder was able to be changed in the threshing teeth and the screw. The indoor test with this cylinder have been carried out. So the foundation of the simulation and the field test for reducing the required power has built up.
