The EP PolyGearbox (RPG) is a compact and lightweight reduction gearbox with an integrated limit switch system that’s ideal for assembly of a locally available electric motor. The PolyGearbox can be used in manually-managed or climate-managed ventilation and screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is rainproof and windproof. The PolyGearbox has a high protection class (IP65) and can be used in an ambient temperature of 0-60 °C.
The low-noise PolyGearbox has a gearwheel transmission and a worm wheel transmission, which are integrated within an aluminium precision housing. The self-braking worm wheel transmitting means that the drive shaft is usually locked when the reduction gearbox isn’t running. The fully sealed reduction gearbox comes with an expansion chamber with a diaphragm to keep carefully the gear oil at a low pressure under all situations, even at high temperature ranges. Thanks to the use of an expansion chamber, the PolyGearbox can be Gear motors for Greenhouse installed in any position. There are no restrictions, because there is no dependence on a bleed connect. The sealed decrease gearbox keeps the apparatus oil of the PolyGearbox in optimum condition for its entire operating lifetime. The PolyGearbox is suitable for discontinuous use, operating course s3-30%, with a maximum activation time of 25 minutes.
The PolyGearbox reduction gearbox comes with an FT85 engine assembly flange, on to which a suitable 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 at the end positions. The limit change system is installed in an integrated chamber and is certainly enclosed by an impact-resistant plastic-type cover. The limit switch system is obtainable and simple to adjust. The limit switch system’s optimum switching range is 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.
