Abstract

The treadmill is family often used in daily life of equipment, it has the advantages of simple structure, high reliability, has been widely used in various places and families. The treadmill is designed according to human body engineering, accords with the general fitness requirements, this design is scientific and reasonable.

This topic is entertainment treadmill, running as the main design object, and driving, power is to provide, and long service life, easy to repair, be on the road a long time running, high safety performance.

Running on a treadmill on the market today is still relatively rare, the main reason is that the market has been part of the structural design is unreasonable, the stability is not high. This leads to the market for the treadmill is rare. This topic design, and strive to design better than the market existing products, improve treadmill shortcomings, the true sense of the extended out to the treadmill.
