The EP PolyGearbox (RPG) is a compact and lightweight reduction gearbox with a limit switch system that’s suitable for assembly of a locally available electric Gear motors for Greenhouse engine. The PolyGearbox is used in manually-controlled or climate-managed ventilation and display screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is usually rainproof and windproof. The PolyGearbox has 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 is usually locked when the reduction gearbox is not running. The completely sealed reduction gearbox comes with an expansion chamber with a diaphragm to keep carefully the gear essential oil at a minimal pressure under all circumstances, even at high temperatures. Thanks to the usage of an expansion chamber, the PolyGearbox could be installed in any placement. There are no limitations, because there is no need for a bleed plug. The sealed decrease gearbox keeps the gear oil of the PolyGearbox in ideal condition for its entire operating lifetime. The PolyGearbox is suitable for discontinuous use, working course s3-30%, with a maximum activation time of 25 minutes.
The PolyGearbox reduction gearbox comes with an FT85 electric motor assembly flange, on to which the right IEC standard motor can certainly 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 switch system is installed in an integrated chamber and is definitely enclosed by an impact-resistant plastic cover. The limit change system is accessible and simple to adjust. The limit change system’s optimum switching range is certainly 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.
