Двигательный асинхронный железнодорожный привод

Abstract

Рассмотрены вопросы создания моторного привода для разъединителей контактной сети электрифицированных участков железной дороги на основе асинхронного двигателя и нелинейной механической передачи, а также вопросы синтеза криволинейного кулисного механизма для данного привода.

The work purpose consists in the development and creation of a new design of the motor drive for circuit breakers of a contact system of electrified railway track sections, the analysis of the curvilinear rocker mechanism synthesis for this drive. A possibility of the curve synthesis for creation of a link ensuring a specified law of motion at the known geometrical parameters of a unit and also specified power and kinematic parameters of input and output units is analyzed. The investigation results allowed developing, designing, manufacturing and testing a motor drive for switching contact breakers of electrified railway sections. The results of this work allowed creating a motor drive with a rocker mechanism consisting of two arched guides which has a possibility to increase considerably a rotational moment imparting to a working element at the moment of the breaker switching on or out.
