Variable Speed Drives

The Grand mechanical variable speed drives consist of variable speed pulley, adjustable base plate, variable speed belt and driven pulley. The automatic variable speed drives are primarily intended for use where fairly frequent speed changes are necessary like textile machines, machine tools, packaging machines, autoclaves, agitators, printing machines, bottling plants, pumps for viscous liquids, biscuit and tea processing lines, conveyors and feeders. The Grand variable speed pulley is double diaphragm type spring loaded pulley. This assembly comprises two facing cone shaped discs each sliding laterally on a sleeve and two diaphragm shaped springs which comprise outer side of cone shaped discs. Through the medium of an equaliser both halves of the pulley move, which ensure perfect alignment of the variable speed V-belt at all speed settings. Two adjusting nuts are fitted on outer side of the sleeve. This adjusting nut helps to adjust spring load on the cone shaped flanges for enhanced variable speed V-belt life. An adjustable motor base with operating handwheel with the help of which motor and pulley assembly can be easily moved forward or backward through this change in the centre distance between driving and driven shaft is the only control required for regulating the speed. This provides versatility to a machine by enabling the right speed in changing conditions in production, reduced manufacturing costs, better and uniform quality of products. These drives are available for up to 25 HP motor and designed for positive speed variation. Dealership enquiries are sought.
