The EP PolyGearbox (RPG) is a compact and lightweight reduction gearbox with a built-in limit switch system that’s suitable for assembly of a locally available electric electric motor. The PolyGearbox can be used in manually-controlled or climate-controlled ventilation and display screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is certainly 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 ensures that the drive shaft is definitely locked when the decrease gearbox is not running. The completely sealed reduction gearbox comes with an growth chamber with a diaphragm to keep the gear oil at a low pressure under all circumstances, even at high temps. Thanks to the use of an expansion chamber, the PolyGearbox could be installed in any placement. There are no limitations, because there is no need for a bleed connect. The sealed reduction gearbox keeps the Gear motors for Greenhouse apparatus oil of the PolyGearbox in ideal condition for its entire operating lifetime. The PolyGearbox is ideal for discontinuous use, working course s3-30%, with a maximum activation time of 25 minutes.
The PolyGearbox reduction gearbox has an FT85 motor assembly flange, on to which a suitable IEC standard electric motor can certainly 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 integrated chamber and is enclosed by an impact-resistant plastic cover. The limit switch 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 has an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
