The EP PolyGearbox (RPG) is a compact and lightweight reduction gearbox with an integrated limit switch system that is suitable for assembly of a locally available electric electric motor. The PolyGearbox is utilized in manually-managed or climate-managed ventilation and display screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is certainly rainproof and windproof. The PolyGearbox has a high protection class (IP65) and can be utilized within an ambient temperature of 0-60 °C.
The low-noise PolyGearbox includes a Gear motors for Greenhouse gearwheel transmission and a worm wheel transmission, which are integrated in an aluminium precision housing. The self-braking worm wheel transmitting means that the drive shaft is certainly locked when the reduction gearbox isn’t running. The completely sealed reduction gearbox has an growth chamber with a diaphragm to keep carefully the gear oil at a low pressure under all conditions, even at high temps. Thanks to the use of an expansion chamber, the PolyGearbox can be installed in any placement. There are no restrictions, because there is no need for a bleed plug. The sealed reduction gearbox keeps the gear essential oil of the PolyGearbox in ideal condition because of its entire operating life time. The PolyGearbox is ideal for discontinuous use, operating course s3-30%, with a maximum activation period of 25 minutes.
The PolyGearbox reduction gearbox has an FT85 engine assembly flange, to which the right IEC standard engine can easily be installed (EN 50347).
The PolyGearbox has a rotating limit switch system with operating switches and circuit breakers (NC contacts) for turning off by the end positions. The limit change system is installed in an built-in chamber and is enclosed by an impact-resistant plastic material cover. The limit switch system is accessible and simple to adjust. The limit change system’s maximum switching range is usually 40 or 64 revolutions of the drive shaft. The cabling is linked in spring-clip connections. The PolyGearbox comes with an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
