SPN has developed, produced and assembled a worm gear unit especially for the drive of a weaving machine. The gear is driven by a toothed belt or by a toothed belt wheel on the worm shaft. The drive set consists of a case-hardened worm shaft and a bronze worm wheel and has a center distance of 80 mm, with a transmission ratio of i=8:1. In order to achieve the target price, among other things the center distance was reduced and a higher power density was achieved. Various auxiliary units are driven by the worm shaft via additional belt wheels. In addition to the helical spur gear, the output shaft also has a sprocket wheel which drives the oil pump of the machine-side continuous lubrication of the gearbox. The axle of the counter gear is clamped by a steel component integrated into the gear housing. The gearbox housing consists of 2 aluminium chill castings.

The machines of our end customer are now in operation worldwide with our gear unit.
