Helical gear units to the spn standard

Do you want to transmit power without maintenance and without slippage, and is the available installation space flat? SPN helical gear units convince through their flat design. But SPN helical gear units are also the best choice when the load is to be distributed over several shafts. A gear unit that is as unique as your application.

We demonstrate our expertise and many years of know-how in the development and production of customer-specific spur gears in several projects. For safety in special switchgear in the distribution of electrical energy for several locations, we supply robust and reliable transmission solutions. The application example for this perfect drive can be found here.

Basic design of helical gear units

A helical gear unit can be designed as a gear train, a step-up gear unit or as a combination of these. Several bevel gears located one behind the other make up a gear train. One gearwheel drives the next, thus connecting the drive to the output. A gear ratio is only provided by the first and last gearwheels of the chain.

In mulitistage step-up gear units a small gear drives a large gear. This is the first transmission ratio. For the second transmission ratio the large gearwheel of the first stage is connected to a small gearwheel, which then drives the gearwheel of the second transmission ratio. At very high rotational speeds only the first gearwheel rotates at the high rotational speed. The other stages are already stepped down, meaning that a helical gear unit is especially suitable for high rotational speeds.
