摘要：
Compression device is the important mechanism of baler. This paper uses the virtual prototyping technology. It analyzes the function of compression device in 9KG-350 high density baler and the three-dimensional digital model of compression device is obtained based on UG package .Then the model is put into ADAMS, and a kinematical simulation analysis is performed. Through the simulation, the whole kinematical process is reflected, gaining the relative kinematical curves of compression device as well. The results can be help in study the design of baler and the structure optimization.
摘要：
Slotting process used to achieve modify heavy-loading mine gear.According to the pitch circle radius of gear tooth profile modification is difficult to accurately draw, reverse-designed the profile of the modification slotting cutter fold may occur on the cusp, generating simulation for slotting profile modification is implemented using MATLAB based on engagement theory of slotting process,which can test whether the pitch circle is set to reasonable, to avoid resulting the top or root of conjugate gear’s profiles be cut,achieved the adaptive design of profile modification slotting cutter.
摘要：
According to the traditional tooth profile, modification process cannot meet the traction gear’s technical requirements of the high-speed locomotive. A new way for the tooth profile modification technology was provided in the paper. The slotting profile modification process was proposed, the formulating methods of the tooth profile modification K diagram was introduced, modification curve fit as the sections of involutes, the modification profile angles of slotting cutter corresponding sections of involutes was deduced using the profile angle error analysis theory and the tooth profile of modification slotting cutter precision was designed. The feasibility and advantages of modification slotting cutter were validated by examples, which indicates the widely use of this technology in high-speed locomotive traction gear.

摘要：
Relative to gear shaping and gear hob, using gear slotting produces herringbone gear which is used in nuclear power turbine speed redactor has more obvious technical and economic benefits, but profile angle error of slotting cutter causes profile error and base pitch deviation of herringbone gear. It will result in high-frequency noise which damages the tactical and technical performance of warship. By analyzed the wire cutting system of rack cutter used in MAAG type gear machining for herringbone gear, the mathematical model of error prediction for rack cutter profile angle was founded. On the base of model of error prediction, the principle of error control and the method of revision control are presented. Finally, the example of prediction and control is provided.
