6 ExchangerWarranty regulations:Reggiana Riduttori guarantees its products for 12 months from the date of warranty shall lose its validity should the defect or anomaly result from the incorrect or inadequate application of the instructions: Upon delivery of the REDUCTION gear check that it has not suffered damage during transport and that all prescribed accessories are present. The REDUCTION gear is intended for use in environments and for applications that are in line with the provisions of the project. All improper use of the REDUCTION gear is prohibited. Replacement or alteration of parts of the machine, that have not been authorized by REGGIANA RIDUTTORI, can give rise to accident risk,and therefore relieve the constructor from any civil or penal responsibility, and cause the warranty to lose its TECHNICAL DATA GENERAL INDEXREDUCTION GEAROUTPUTREDUCTION GEARINPUTCLOCKWISEDIRECTIONCOUNTERCLOCKW ISEDIRECTIONThe rotation directionof any mechanical element (shaft,cogged wheel, pulley, etc.)

8 Defined as the ratio between the output power and the input power of the REDUCTION value of the efficiency limited to only the PLANETARY REDUCTION gear , single stage in conditions of average speed and torque T2,equals This value decreases in the following cases: Decrease in the torque applies Increase in rotation speed REDUCTION GEARS in multistage configurationThe value of the efficiency of angular REDUCTION GEARS is usually lower than that of the linear REDUCTION functions, range of applications and expected useReggiana Riduttori PLANETARY REDUCTION GEARS are designed to implement power transmission inside operator machines. They canbe connected directly or indirectly to an electric or hydraulic REDUCTION GEARS are used for many different applications, both industrial and mobile, for example the mechanical industry,the chemical and plastics industry, the food industry, building and construction, mining/ extraction, agriculture and forestry, transportand hoisting, the naval sector and wind energy the REDUCTION gear only for the purposes it has been designed for.

9 If it is used improperly it could be dangerous for thesafety and health of people. The purposes for which these REDUCTION GEARS have been created and made are industrial and torqueT2 This is the value of the torque transmitted in continuous operation with service factor fs =1, equaling a theoretical life of 30000 n2xhcorresponding to million revolutions of the output shaft. This value is given in for each size of REDUCTION r que T2 is limited by the surface resistance and by the resistance to flexure of the teeth of the GEARS in compliance with the standardISO6336. For the right choice of the REDUCTION gear , when the life requested is far from 30000 n2xh, multiply the value of the torqueT2 by the corrective coefficient Tf given in graph 2 on page torqueT2 MAXThis represents the value of the maximum torque allowed in output for brief periods or for occasional peaks, without permanentdamage being made to the most stressed elements.

10 In general it equals T2x , making sure that this value does not exceed thatgiven in When the loading conditions foresee frequent start-ups, frequent inversions or long times at the maximum torque, limitthe value of the torque installed or select a greater size of REDUCTION input speed n1 MAXThis indicates the maximum speed allowed in input for brief periods or inintermittent operation; the value is given in for each size of reductiongear, both in linear and angular conformation. The input speed of thereduction gear is limited by the peripheral speed of the GEARS , the bearingsand the seals. For an angular REDUCTION gear we advise not exceeding 1500min-1 in continuous operation, otherwise the noise level rises considerablyand the temperature increases due to the oil shaking.
