Drive for driving worm gear of e.g. side degassing unit of extruder, has internally toothed drive wheels twisted relative to each other, and drive shafts connected with worm gears and including drive gears, which cog with respective wheels

摘要

The drive (9) has internally toothed drive wheels (17, 18) of same diameters twisted relative to each other and fixed in a twisting position. A drive gear is driven by a drive motor (10) and cogs with one of the drive wheels. Drive shafts (20a, 20b) are connected with worm gears (8a, 8b) and include drive gears (19a, 19b), which cog with respective drive wheels. The drive shafts are rotatably mounted at housing covers (15, 16) of a housing (13). An elongate hole is provided at one of the drive wheels in a defined radius.
