多功能电动跑步机的设计（机械CAD图纸）.doc

摘要 跑步机是家庭及健身房常备的器材，而且是当今家庭健身器材中最简单的一种，是家庭健身器的最佳选择。专家们相信未来跑步机市场将以高价位产品为主导。低价位产品销售也不错，近几年价格已有上升趋势。注重生活时尚的消费者认为跑步机价格在 1000美元以上是理所当然的事。这些迹象表明，未来跑步机仍会持续增长。 Abstract The race apparatus is the family and apparatus always on the alert of gymnasium, and the simplest one in the body-building apparatus of the current family, it is the best choice of the family building up body device . The experts believe the race apparatus market will take high price products as the leading factor in the future. Low price products sell too good, price in recent years had the tendency to rise. Pay attention to consumers with fashionable life and think the price of the race apparatus is the natural thing above 1000 U.S. dollars. These signs indicate , the race apparatus will still increase continuously in the future. Have used the three-dimensional entity software SOLIDWORKS to carry on the entity modeling of the part in the course of designing, design with the ensemble architecture . Design and include the support , the base shelf , the cylinder , run board, is it bring to run, design consult domestic and international every brand structure and design, carry on accurate calculation by organization to transmission, and design stress shock attenuation systematic importance and run the static -proof functionality of the board especially, the design enables persons who run to experience the strength of the race apparatus. Because of the particularity of the race apparatus, safe problem is worth paying close attention toer, how to use the race apparatus correctly, it is as important as maintenance of the race apparatus.
