Table 1 Technical data (1) Intermittent operation: permissible values may occur for max. 10% of every minute. (2) Peak load: permissible values may occur for max. 1% of every minute. (3) At speeds lower than those given, the motor cannot be expected to run evenly. (4) If no drain line is fitted, the built-in check valves ensure that the case pressure is equal to the pressure in the return line. The max. case pressure for OMSU is dictated by the technical data of the component to be attached. OMSU motors have built-in check valves.

10 Internal spline data for the component to be attached The attached component must have internal splines corresponding to the external splines on the motor cardan shaft (see drawing below). Case hardening steel with a tensile strength corresponding at least to 20 MoCr4 (900 N/mm2). See also SAE 8620 for further information on steel material. Internal involute spline data Standard ANS B92. 1-1970, class 5 (corrected m • x = 0.8; m = 2.1166) Table 3 Internal involute spline data WHITE can accept no responsibility for possible errors in catalogues, brochures, and other printed material.

Drain connection on OMSU or attached component The case pressure is released to the motor return pressure by the motor drain hole (0 5 mm) and the incorporated check valves. A drain line ought to be used when pressure in the return line can exceed the permissible pressure on the shaft seal of the attached component. The drain line can only be connected to the drain connection of the attached component, i.e. the OMSU motor has no external drain connection. The drain line on the attached component allows oil to flow freely between component and the motor. The drain line must be led to the tank...

Maximum tightening torque Maximum tightening torque Table 4 Maximum tightening torque In order to make sure that the OMSU counterpart is correct, the drain flow should be measured on the first of each new application. Any subsequent modification of the counterpart should imply new checking. When the motor is fitted onto the counter part with the correct tightening torque, the drain flow is measured at Q = 30 I/min and an oil viscosity of 35 mm2/s at differential pressure: Table 5 Differential pressure After a minimum of 5 min. of operation the drain flow shall be minimum 0.03 l/min and maximum...
