Worm gears

Worm gears are helical gears and where the rotary motion of a worm gear on a cylindrical shaft is transmitted to a rotating gear wheel that is offset by 90°. These gears allow a particularly high gear ratios in a confined spaces and are therefore ideal for use in tight spaces.

The worm gear consists of two components: a threaded worm shaft and a threaded worm wheel. The worm shaft is usually made of steel and the worm wheel is usually made of bronze.

Worm gears are high-precision and very strong offset gears. They are mainly used when a large overall gear ratio is required. With a worm gear and worm wheel, a large overall ratio can be achieved with fewer steps. This means that a smaller, less expensive gearboxes can be used.

These high-performance gears meet our requirements every time and in every respect and are used in demanding applications such as conveyor systems, mills and bucket elevators, extrusion machines, machine tools or separating machines.

    Due to its mode of operation, a worm gear enables large transmission ratios into the slow range. In worm gears, the two shafts cross at a defined distance (A).

  • Duplex worm gearboxes

    Duplex worm gearboxes

    The duplex worm gear is a series of high-precision servo gears for applications that require low backlash. This gear offers a very small torsional backlash and very high torsional rigidity.

Repair and services

The quality of our gearboxes is an important part of our philosophy. We try to design our gearboxes according to the needs of our customers in such a way that we meet both the requirements for performance and economy.

For FLOHR, however, customer service does not end with the handover of the product. Each of our gearboxes is well documented and should should give you a long service life. We also offer a full repair and maintenance service for all of our gearboxes.

In order to be able to provide any type of repair and service as quickly as possible, we offer our customers a well thought-out service strategy, which also includes the storage of special parts and a rolling exchange of strategically relevant parts. In conjunction with this, we offer a  repair, maintenance and service for all of our customers' transmissions, irrespective of brand. With a quick and professional damage analysis, you will immediately receive a cost estimate for the necessary repair measures. After approval, we guarantee reliable processing of the repair or service order.

Thanks to our service strategy, we have already had very good experiences with our customers. Together with you, we agree on maintenance intervals in order to prevent damage and reduce downtimes to a minimum. However, should an unscheduled problem occur, you will be immediately supported by our team.

Talk to us about the service and maintenance concepts - we will be happy to support you with your planning!
