Hydraulic Cylinder (Optional); Helical­gear Unit; Stroke­mounting Flange; Stroke­mounting Flange With Bevel­gear Motor - Siemens FLENDER H3LV Assembly And Operating Instructions Manual

5.2.4.2 Hydraulic cylinder (optional)

The hydraulic cylinder is connected to the stroke­mounting flange and the adapter sleeve located inside
it. In this way the insert shaft of the helical­gear unit can be vertically adjusted. When mounting, the
mounting dimensions specified on the dimensioned drawing must be observed.
Note
Be sure to observe the operating instructions for the hydraulic cylinder for operation and maintenance.
For technical data, refer to the data sheet and/or the list of equipment.
5.2.5 Helical­gear unit
The torque is transmitted to the vertically adjustable, upwardly protruding insert shaft via a multi­stage
vertical helical­gear unit with shafts fitted on rolling bearings and a hollow output shaft provided with
splines.
The oil is fed to the toothed parts, the rolling bearings and the splines on the hollow shaft and the insert shaft
by splash lubrication. The gear unit thus requires very little maintenance.
5.2.6 Stroke­mounting flange
5.2.6.1 Stroke­mounting flange with bevel­gear motor
The insert shaft is height­adjusted on the drive via the spindle drive inside the stroke­mounting flange. It is
fitted on below the helical­gear unit in the area of the output shaft. The spindle is guided in the
stroke­mounting flange by means of rolling bearing. This rolling bearing is adequately dimensioned to
enable it to absorb the axial forces exerted.
The drive journal of the spindle projects downwards from the stroke­mounting flange. Two shaft­sealing
rings at the shaft outlet prevent oil from escaping.
The rolling bearing and the spindle drive are also lubricated by splash lubrication. The stroke-mounting
flange together with the helical­gear unit form a common oil chamber.
5.2.6.2 Stroke­mounting flange with lifting cylinder
The stroke­mounting flange is attached below the helical­gear unit in the area of the output shaft (insert
shaft). Using an attached hydraulic cylinder, the insert shaft can be vertically adjusted via an adapter
sleeve with internal rolling bearing.
This rolling bearing is adequately dimensioned to enable it to absorb the axial forces exerted.
The rolling bearing is lubricated by splash lubrication. The stroke-mounting flange together with the
helical­gear unit form a common oil chamber.
The junction of the stroke­mounting flange and the hydraulic cylinder is sealed with gaskets. If gaskets
made from PTFE are used, they should be preheated to 60 to 80 °C in an oil or water bath before fitting.
When the gasket has been placed in the groove on the intermediate cover, the piston rod of the hydraulic
cylinder must be inserted (for calibration).
5.2.7 Gear­unit cam-operated switch (optional)
The gear­unit cam-operated switch is fitted with four freely adjustable cam operated switches for
positioning the spent­grain cutting machine and a rotary­angle transducer to indicate the lifting distance.
The gear­unit cam operated switch must be adjusted by the system constructor before start­up.
Note
Be sure to observe the operating instructions for the gear­unit cam operated switch for operation and
maintenance.
For technical data, refer to the data sheet and/or the list of equipment.
