The Ridder RW motor gearboxes are maintenance-free, compact power sources for driving vent, screen, hoist and flap ventilation systems in greenhouses and barns. The key features of these dives are a self-braking work gear transmission, and a built-in linear limit switch system. There is a broad range of electric motors available to enable the Ridder RW motor gearboxes to be applied worldwide.
The gearbox of a RW motor gearbox consists of a combination of pinions and worm gear transmissions that have been matched for low-noise mechanical power transmission. The RW motor gearbox’s self-braking worm gear transmission ensures that the output shaft will brake when the drive unit is stopped. Because Ridder has opted for the most compact possible design for the RW motor gearboxes, with a relatively high output drive moment, the RW motor gearboxes are only suitable for intermittent running (duty cycle s3, running time 30%).
Ridder can supply a wide range of mounting plates, each of which is designed to match a specific type of system. A sprocket is supplied standard on every RW motor gearbox. The RW motor gearboxes are coupled to the drive shafts of the system to be driven, with the aid of chain coupling sets. The use of chain couplings enables undesirable effects to be relieved, such as minor off-centering and misalignments. This is beneficial for the drive system.
All RW motor gearboxes include the capability of being manually driven by means of a hexagon in the electric motor shaft. This enables the system to be manually driven e.g. during installation, or in the event of a power failure. Ridder RW motor gearboxes are finished in graphite-gray powder coating and are supplied including fixing bolts and spring washers.
