Elecon Engineering Company Limited

worm extruder gear unit consist of worm gear unit where on the hollow shaft thrust bearing is mounted on a seperate housing which has a capacity of absorbing heavy thrust induced during the process of plastic extrusion. The hollow shaft is with a provision of internal splines for ease of process.

these type of worm extruder gear units are an economical drive assembly for low power plastic extruder.

available sizes are 4", 5", 6", 7", 8", 9" and 10. 5"

the boggie drive unit consists of double side helical and at the center a worm gear unit which is specified as double heli-worm gear unit.

the boggie drive arrangement is used where bridge scrapper for lime stone is required to stack and for that this gear boxes are used at two different speeds.

shunting speed (high speed) - this is achieved through an a. C. Motor which drives worm gear unit through coupling (on rh side).

reclaiming speed(low speed) - this is achieved through d. C. Motor which is driven helical gear box and driving worm gear unit (on lh side).

elecon has developed above 17" center distance gear unit in the size 24" & 28" for special purpose applications.

24" size is developed in underdriven mounting position used for opening heavy duty gate on water dam.

28" size is developed in underdriven mounting position for double reduction gear unit(14/28) size for an application of launching pad platforms used at isro shar center, sriharikota.

the casing of the gear box is of welded construction and mainly in two parts.
