All worm gearboxes series U-MU are accomplished in a special version with primary reduction stage.
There are four types of primary reduction units which are usually combined with worm gearboxes: P 63 – P 71 – P 80 – P 90; the number characterizing each size is actually the size of the motor in B14 construction, which can be fitted with a certain primary reduction.
Each type of primary reduction unit can be made with two different ratios: 3/1 si 4/1. therefore, the highest ratio achievable with a primary reduction is 400/1.
The primary reduction of the worm gearboxes has the great advantage of being able to be used even for applications different from their connection with a worm gearbox, and can be even used as a single separate reduction unit.
Worm gearboxes can be used in different industrial domains such as: food industry, belt conveyors and conveyors in general, mixers, agitators, dosing machines, bread machines, packaging machines, printing machines, industrial automation equipments, wood processing machines.
