In order to meet the demand for specific environments, such as for the following sectors: food, pharmaceuticals, shipbuilding, chemical, textile, paper, photographic, etc, the stainless steel right angle gearbox has been engineered. In all ratios, the housings and both input and output shafts are manufactured from stainless steel AISI 316. The main advantages of AISI 316 steel compared to AISI 304 steel are the best corrosion resistance and the wider range of applications. In particular, AISI 316 performs an excellent corrosion resistance in the atmosphere (normal atmosphere and sea atmosphere), and an excellent corrosion resistance against a variety of substances, including food, which are usually critical for steels. The outer housing is ergonomically designed to prevent interleaving of liquid or powder. The surface is electro-polished and bead blasted, and the shafts are ground. Upon request, according to minimum amounts, our stainless steel right angle gearboxes can be produced with the external parts of shafts according to customer’s drawing for all ratios.
The gearboxes are engineered for an input speed (shaft A) of 1400 rpm. They can even be used at speeds up to 3000 rpm. The permissible temperatures for trouble-free running of gearboxes should be kept within -18°C and +80°C (0°F and 170°F). In particular conditions of temperature, please consult our technical department. High accuracy assembly ensures low operating noise levels, even at high running speeds. Angular clearances between gears are hold within 15’ and 30’. On request the gearboxes can be supplied all right angle gearboxes with reduced angular clearances. All units are factory filled with lubricant. The series R5000 gearboxes are lubricated with synthetic oil. Being lubricated for life, they do not require any periodical oil filling up nor any oil change. For particular applications, according to minimum quantities, it is possible to produce these right angle gearboxes with oil types as requested by customer. Thanks to the construction shape, the mounting of gearboxes is allowed in any position. The only requested caution is to advise a possible mounting with a shaft in vertical position, in order to provide the proper lubrication.
The gearbox housing is compact and made of stainless steel AISI 316, whose main feature is an excellent corrosion resistance. The fixing flanges with threaded holes, and other guides allow the mounting in any position. The GLEASON spiral bevel gears are made of alloy, carburized, hardened steel. Shafts are made of stainless steel AISI 316. For particular applications, according to minimum quantities, we can produce right angle gearboxes with special shafts with all the standard dimensions of the housings. All shafts are rotating on generously sized and high quality ball bearings of first class brands. Standard oil seals are made in NBR. For special applications, on request we can supply right angle gearboxes with special oil seals.
