this paper put getting value range of back-passing oil cylinder installation angle and tush plank inclination.

The paper explores an analysis on the working and mechanical conditions of milling and cutting bifunctional tools on soil stabilizer rotor,and thus advances setting principles for the milling tool s anterior angle,relief angle and installation angle.

This paper describes the deviation occurred in the process of manufacturing and processing multi -stage axial -flow compressor between blade s angle and design value and this kind of deviation will cause the variation of blade s installation angle.

Method for determining setting angle of mixer s blades;

The formulas for setting angle and entrance angle of disc cutters are derived by using the contact condition of space curve.

The grass removing angle and setting angle of straw-mulching bent blade of the straw-returned-native-field machine (Model: 1ZT-210) were described in the paper.

Research on the installing angle of shearer pick-shaped cutter;

The paper discusses the relations of pick installing angle to cutting drum forces,specific energy consumption and service life of drum plate and picks and gives reasonable range of pick installing angle.

In this paper, the quantitative relation between the mounting angle of boring tool and boring cutting face outline in boring process can be reasoned from discussing the movement of rotation error of boring machine spindle, thus it is possible to optimistically seek mounting angle so as to obtain the best processing effect.

Aiming at investigating how the air horn and mounting angle affect a Pitot tube measurement, experiments were carried out on various Pitot tubes.

After the installing angles of harrow and blade were adjusted,the obvious effect was gained,and the nomal operation was ensured.
