The optimization of the gear modification coefficient of the dryer decelerator in paper machine;

Method of selecting modification coefficient of involute internal gear with zero-tooth-difference mechanism;

Modification coefficient choose of the involute planetary gear drive with small teeth difference based on CAD;

A study on the selection of position-shift coefficient of GSC was made,and a CAD system of GSC with 3D modeling and simulation by VC++ was opened up.

This paper makes a study on the selection of position-shift coefficient of GSC, and development of a CAD system of GSC with 3D modeling and simulation.

This paper makes a study on the selection of position-shift coefficient of GSC, and achieves in the following two aspects:1 put forward a mathematical model for selection of position-shift coefficient.

In allusion to the existing difference of selecting living consumption water quantity standard,this paper calculates the day and hour variety coefficient through testing calculation according to the population and construction age,and put forwards the living consumption water quantity standard in Shengyang City and provides the science reference for the water supply plan and design.

Constituting the quota system,the paper gives the degree of correspondence of this capability by variety coefficient of statistics, and proceeds with the simulative study.
