of the teeth and the load on the rolling-contact bearings, and so has an influence on the service life of the gear unit. All points on the gear unit mounting surface must lie between two imaginary parallel planes that are 0.1mm per 1m apart. Design the foundation frame according to the relevant weight and torque, taking into ac- count the forces acting on the gear unit. The feet of the gear unit must be properly suppor- ted. Base frames or substructures that are too soft can result in radial or axial displace- ment during operation. This displacement is not measurable when the drive is at stand- still. Procedure To install the gear unit on foundation frame, proceed as follows: 1.Clean the underside of the gear unit feet. 2.Use suitable hoisting gear to set the gear unit down on the foundation frame. 3.Tighten the foundation bolts to the specified tightening torque ( Page . If necessary, install stops to prevent displacement. 4.Align the gear unit precisely with the input and output equipment ( Page . 5.Record the alignment dimensions. 6.Keep the report in safe place together with these operating instructions. NOTICE Damage caused by unevenly tightening the fastening bolts The gear unit can be damaged by unevenly tightening the fastening bolts. Evenly tighten the fastening bolts. When tightening the fastening bolts, make sure that the gear unit is free of mechanical stress. 5.3.2.3 Mounting on concrete foundation using stone bolts or foundation blocks 5.3 Gear unit assembly Requirements The lower side of the gear unit mounting feet must be clean.
