New Mechanical Solutions for Highly Efficient Gears

Traditionally, worn gears are used for lift speeds up to 1.6 m/s. There is also the possibility to use multiple threat worm gears for speeds up to 2.5 m/s. New developments include teeth gears and planetary gears. This paper describes an unconventional solution of a V-belt driven machine. With the aid of standards relating to V-belt drives, the paper then describes the design requirements for their use in elevator machines. Finally, a comparison of the features of V-belt and conventional machines helps to highlight the applications in which V-belt drives can provide a cost-effective and convenient solution.
