Determination of gear unit type and size 1.1.Find the transmission ratio 1.2.Determine the nominal power rating of the gear unit It is not necessary to consult us, if: 1.3 Check for maximum torque ..: peak operating, starting or braking torque Gear unit sizes and number of reduction stages are given in rating tables depending on iN and P2N. 1.4 Check whether additional forces on the output shaft are permissible; it is essential to consult Siemens! 1.5 Check whether the actual ratio as per tables on pages 3/6 to 3/6 is acceptable.2. Determination of oil supply: Horizontal mounting position () Dip lubrication (all parts to be lubricated are immersed in the oil or are splash lubricated) Oil circulation lubrication by means of flange-mounted pump (type H1 only) Vertical mounting position () Dip lubrication with oil expansion unit Forced lubrication on request Upright mounting positions (, ) Dip lubrication with oil expansion unit Forced lubrication on requestn1 n2is = P2N P2 f1 f2 P2 P2N 3.3 TA n1 9P2N f3 Siemens AG 2 Design of the gear units Guidelines for selection Constant mechanical power rating 3/3 Siemens MD 3.1 2Overview (continued) 3.
