The EP PolyGear motors for Greenhouse gearbox (RPG) is a concise and lightweight reduction gearbox with an integrated limit switch system that is suitable for assembly of a locally available electric motor. The PolyGearbox is utilized in manually-controlled or climate-managed ventilation and display systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is definitely rainproof and windproof. The PolyGearbox includes a high protection class (IP65) and can be used within an ambient temperature of 0-60 °C.
The low-noise PolyGearbox includes a gearwheel transmission and a worm wheel transmission, which are integrated within an aluminium precision housing. The self-braking worm wheel transmission ensures that the drive shaft can be locked when the decrease gearbox is not running. The fully sealed reduction gearbox comes with an growth chamber with a diaphragm to keep carefully the gear oil at a low pressure under all circumstances, even at high temperatures. Thanks to the use of an expansion chamber, the PolyGearbox can be installed in any position. There are no limitations, because there is no need for a bleed plug. The sealed reduction gearbox keeps the gear oil of the PolyGearbox in ideal condition for its entire operating life time. The PolyGearbox is ideal for discontinuous use, operating class s3-30%, with a maximum activation period of 25 minutes.
The PolyGearbox reduction gearbox has an FT85 motor assembly flange, on to which the right IEC standard engine can simply be installed (EN 50347).
The PolyGearbox has a rotating limit switch system with operating switches and circuit breakers (NC contacts) for turning off at the end positions. The limit change system is installed within an integrated chamber and is definitely enclosed by an impact-resistant plastic-type material cover. The limit change system is accessible and easy to adjust. The limit change system’s maximum switching range is usually 40 or 64 revolutions of the drive shaft. The cabling is connected 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.
