Abstract
This graduation design is about the design of the six slot steel machine. First of six trough moving steel machine has made the simple outline; then analyzes the six slot steel machine type selection and calculation method of displacement. Then according to these design criteria and selection method in accordance with the given parameters requirements selection of design; then on the selected six tank shift steel machine and the main components were checked. Groove in the shift steel machine design, manufacturing and application, at present our country and the overseas advanced level compared to still have a large gap, in the design and manufacture of domestic six trough steel moving machine process exists many problems.The whole structure mainly by the motor generates dynamics will require the power through the coupling transfer to the gear, through the gear and the transition to another set of gear, and then through the transition gear to worm. At the same time, the paper on the six slot shift steel machine is the key part of the design process are detailed. The main contents include the design of the overall scheme of the system design, motor selection, actuator design, transmission parts, the shaft of the design and check and bearing selection, etc..
This paper mainly introduces the groove shift the development condition of the steel machine, the six slot shift steel structure design principle, six trough shift the overall scheme of steel machine analysis and determination, the six slot shift steel structure design content contained in the mechanical drawing of rendering, the calculation of structure design conclusion and suggestions.
Research content of this thesis:
(1) the overall structure design of the six slot steel machine.
(2) analysis of working performance of the six slot machine.
(3) motor selection.
(4) transmission system and executing component of the six slot machine.
(5) design and calculation analysis and verification of design parts.
(6) drawing the assembly drawing and the assembly drawing of the important parts.
Key words: Six slot machine, transmission device, connecting rod, reducer
