Abstract

The treadmill in the society now has become the majority of the people in the limited places to exercise the main way, and the multifunctional treadmill for most people favor. Because of its small land occupation, complete function, can achieve effective fitness for purpose, being broad masses place needs.

The design of the main research contents include the overall functional design, transmission design, shape design, front and rear drum design. According to the research content of each part can be divided into: the overall functional design ( has been determined experimentally human body structure and movement characteristics, and according to their exercise given the care needs ) including basic function, structure design and functional principle of determination; transmission mechanism design includes motor type, power selection and technical parameters, transmission mechanism design and parameter selection multi wedge belt pulley, the structure and size selection and belt tensioning device selection; shape structural design includes a frame design and stent design; before and after the drum design includes bearing calculation, shaft strength calculation and design requirements and drum. At the same time also includes the running plate and a running belt design, use and maintenance.
