The EP Greenhouse Gearbox is a compact and lightweight reduction gearbox with a limit switch system that is ideal for assembly of a locally available electric motor. The Gearbox can be used in manually-managed or climate-controlled ventilation and display systems in greenhouses. The quick and easy-to-installEP Gearbox can be rainproof and windproof. The Gearbox has a high protection course (IP65) and can be used within an ambient temperature of 0-60 °C.
The low-noise Gearbox for Greenhouse includes a gearwheel transmission and a worm wheel transmission, which are integrated in an aluminium precision housing. The self-braking worm wheel transmitting ensures that the drive shaft is locked when the reduction gearbox is not running. The completely sealed reduction gearbox has an expansion chamber with a diaphragm to keep carefully the gear oil at a minimal pressure under all circumstances, even at high temperatures. Thanks to the use of an expansion chamber, the Gearbox could be installed in any position. There are no restrictions, since there is no dependence on a bleed plug. The sealed reduction gearbox keeps the gear essential oil of the Gearbox in optimum condition because of its entire operating lifetime. The Gearbox is suitable for discontinuous use, operating class s3-30%, with a maximum activation time of 25 minutes.
The Gear box reduction gearbox has an FT85 motor assembly flange, on to which the right IEC standard motor can easily be installed (EN 50347).
The Gear box has 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 in an integrated chamber and is definitely enclosed by an impact-resistant plastic cover. The limit change system is obtainable and easy to adjust. The limit switch system’s optimum switching range is usually 40 or 64 revolutions of the drive shaft. The cabling is connected in spring-clip connections. The Gearbox has an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
The Gearbox for greenhouse includes 16 teeth 5/8”x3/8” sprockets, keys and fasteners. The accompanying chain couplings and assembly plates are available as gear reduction motor accessories.
