DRIVE TECHNOLOGY OIL EQUIPMENT TECHNOLOGY NEW DEVELOPMENTS HOME " ABOUT COMPANY " PUBLICATIONS " ARTICLES " Nrv gearboxes - applications NRV series gearboxes and their application NRV worm gearboxes have a simple and reliable design. All component parts are enclosed in a casing of a universal shape, so the design of the gearbox has a low noise level and high performance. All housings correspond to the connection dimensions. This unification makes it possible to replace defective gearboxes from other companies. The unit is mounted in any position that requires production needs. The NRV gearbox is available in 9 standard sizes. The gearbox housing is made, depending on the standard size, from an aluminum alloy or cast iron. Cast iron housings are used in gearboxes that are designed for high loads. The NRV gearbox is single-stage according to its operating principle. The maximum radial load can be up to 16,500 Nm. The gearbox is very compact. Its high and reliable operation at a low price for the mechanism is the most optimal on the market of drive mechanisms and equipment. The power of NRV gearboxes is distributed according to the size. Gear ratios range from 5 to 100. Gears are made of high grade bronze alloy. Gear wheels are ground. The gearbox is connected to the motor by means of FRC or SKF couplings. But it is also possible to connect using a belt drive through pulleys. To connect the gearbox output, it is advisable to use chain couplings or chain drives on sprockets. The NRV worm gearbox is conveniently and comfortably serviced. Gearbox housings are painted in accordance with DIN 1843. Blue polyepoxy paints are used for painting. Gearboxes are used in many branches and industries. Without such gearboxes, it is difficult to imagine the normal work of machine builders, food workers, agricultural producers. Before mounting, check the gearbox housing for leaks. If a leak is found, it must be repaired and the oil topped up to normal. Maintenance of NRV gearboxes is carried out according to the provisions of the enclosed manufacturer's instructions.
