Title The Three-dimensional Modeling of the Serialized HVA Vacuum Gate Valves
Abstract Lights has become a common street lighting tool in the Modern society .it is a great convenience to our lives .However, street maintenance and repair, but there are many problems, Markets need a safe and reliable lift lights . This paper describes the use of two sets of worm gear transmission, and were driven reel and the cam in order to achieve uniform lifting program, The device consists of motor, reducer, worm groups, cams, winding wheel, steering wheel, control circuitry and shade, couplings and other associated hardware components. This paper introduces the design background, institutions overall design, dynamic analysis and verification, location and connections, focusing on the overall design and analysis check. On this basis, draw two-dimensional and three-dimensional drawings, guiding production.
Keywords : worm cam reel reducer wiring
