Order information for servo gearmotors R, F, K, S, W gear units NOTE Direction of rotation of the output shaft The following order information is required for R, F, K and S gear units and gearmotors in addition to the mounting position to exactly determine the design of the drive. This information is also required for Spiroplan gearmotors (W gearmotors) that do not depend on a particular mounting position. CCW CW Figure 0: Output direction of rotation As viewed at the output shaft: Clockwise (CW) = Rotating clockwise Counterclockwise (CCW ) = Rotating counterclockwise AXX Position of the output shaft and output flange In right-angle gear units, you also have to indicate the position of the output shaft and the output flange: A or B or AB B B CCW A CW A 0 Figure : Position of the output shaft and the output flange AXX Catalog Synchronous Servo Gearmotors

3 M M M Order information for servo gearmotors R, F, K, S, W gear units Position of output end in right-angle gear units In shaft mounted right-angle gear units with a shrink disc, you also have to indicate whether the A or B side is the output end. In Figure, the B side is the output end. The shrink disc is located opposite the output end, here on the A side. In shaft mounted right-angle gear units, the "output end" is equivalent to the "shaft position" of right-angle gear units with solid shaft. B A Figure : Example: Position of the output end AXX NOTE You will find the permitted mounting surfaces (= hatched area) in the mounting position sheets (page ff). Example: Only the mounting surface at the bottom is possible with helical-bevel gear units K/K in mounting positions M and M. Changing the mounting position Make sure to read the following information when you operate the gearmotor in a mounting position other than the one indicated in the order: Adjust lubricant fill quantity to match the new mounting position Adjust position of breather valve For helical-bevel gearmotors: Contact the SEW-EURODRIVE customer service prior to changing to mounting position M or M and when changing from M to M or vice versa. For helical-worm gearmotors: Contact the SEW-EURODRIVE customer service when changing to mounting position M or M. Catalog Synchronous Servo Gearmotors

TorqLOC mounting system for gear units with hollow shaft Description of TorqLOC The TorqLOC hollow shaft mounting system is used for achieving a non-positive connection between customer shaft and the hollow shaft in the gear unit. As a result, the TorqLOC hollow shaft mounting system is an alternative to the hollow shaft with shrink disc, the hollow shaft with key and the splined hollow shaft that have been used so far. The TorqLOC hollow shaft mounting system consists of the following components: Figure 9: Components of the TorqLOC hollow shaft mounting system 99AXX [] Customer shaft [] Shrink disc [] Locking collar [] Conical steel bushing [] Conical bronze bushing [] Fixed cover [] Hollow shaft in gear unit Advantages of TorqLOC The TorqLOC hollow shaft mounting system is characterized by the following advantages: Cost saving because the customer shaft can be made from drawn material up to quality h. Cost saving because different customer shaft diameters can be covered by one hollow shaft diameter and different bushings. Simple installation since there is no need to accommodate any shaft connections. Simple removal even after many hours of operation because the formation of contact corrosion has been reduced and the conical connections can easily be released. 0 Catalog Synchronous Servo Gearmotors

Lubricants and fill quantities R, F, K, S, W gear units General information Unless a special arrangement is made, SEW-EURODRIVE supplies the drives with a lubricant fill adapted for the specific gear unit and mounting position. The decisive factor is the mounting position (M...M, chp. "Gear Unit Mounting Positions") specified when ordering the drive. You must adapt the lubricant fill in case of any subsequent changes made to the mounting position ( Lubricant fill quantities). NOTE SEW-EURODRIVE fills the gear units with the amount of oil specified for the specific mounting positions. If the mounting position is changed, the amount of oil must be adapted as required. Consequently, a mounting position may only be changed after consultation with SEW-EURODRIVE, otherwise your right to claim under warranty no longer applies.
