| description | FIELD: mining. ^ SUBSTANCE: invention refers to driving facility for sprockets of chain drives, particularly to drive of scraper-chain transporters or chain plane knives for underground mine developments. Drive incorporates the asynchronous electric engine and a gear box. Also the asynchronous electric engine consists of an engine with feeding from a frequency converter, while there is an intermediary two-speed sprocket gear box in the driving block between an engine shaft and the gear box; the intermediary gear box is designed in particular as the front gear box with one starting and one normal stage, when by means of the latter starting effect in the starting stage can be achieved, which is required for starting of loaded scraper-chain conveyer or for free pulling of the chain plane knife. ^ EFFECT: regulating rotary speed and torque of asynchronous electrical engines. ^ 22 cl, 3 dwg |
