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