Abstract
The paper studies on the topic of JWB100Ball screw elevator design. Mainly on the worm gear, worm gear screw transmission parts of the design, with the lead screw, worm, worm gear as the main research object, its work force, material strength, stiffness, toughness and thermal performance were analyzed, and the lift device characteristics and use, to determine the worm gear, worm screw two transmission devices as the main transmission design, developed a worm gear, worm, screw between the structural design. To complete the structure design, drawing auxiliary tool for drawing Auto CAD 3 A0 drawings, clear expression of the JWB100Ball screw lift structure characteristics and performance. Design of the worm screw lift that can be used in single machine, also can be used in combination. According to certain procedures to accurately control the restructuring to enhance or promote height, can be used to directly drive the motor or other power, and can also manually. It has different forms of structure and form of the assembly, the device can lock. Widely used in machinery, metallurgy, construction, water conservancy facilities and other industries, has the advantages of compact structure, small volume, light weight, wide range of power, no noise, convenient installation, flexible use, multiple functions, supporting form, high reliability, long life and many other advantages. Keywords: Elevator；Screw；Worm；Crane
