Helical gearboxes are a group of drives in simple or offset axles. One, two or three pairs of gears can work together in this type. Helical gearboxes are fixed to the device with a foot or flange. A characteristic feature of these drives is their high efficiency of up to 95%. The gear units can be equipped with a flange connection for IEC or NEMA electric motors, a flange connection for servomotors, an integrated compact motor or a solid input shaft with a keyway.
Motovario helical gear units are marked with symbols: H, HA, CH, CHA, IH, IHA, PH.
The gearing range of helical gearboxes is in the range from I=1.23 to I=353,98.
Versions with ATEX certificate are available for operation in potentially explosive areas.
