Dimensional Drawing NOTE Stromag GmbH strongly emphasises that the technical details, such as dimensions, weights, tolerances, tightening torques and other technical specifications and units required for assembly, such as securing devices and lubricants, must be obtained from the dimensional drawing.
Structure and function Component designations Fig. 4 Gear part Flange Switch component Drive shaft, design with parallel key Housing, IP65 shown as an example Cam disc in the gear part Adjustment worm Design, task and function of the assembly groups The GCLS consists of a gear component (1) and a switch component (2), which are accommodated in a housing (3).
5.2.3 Drive The following mounting conditions must be observed: • If possible, the drive should be engaged via a flexible connection, a flexible diaphragm coupling for example. • The ideal drive is carried out over a torsionally-stiff flexible coupling with low axial and radial restoring forces. This compensates for any misalignments and offsets, e.g.
5.3.2 Block adjustment Fig. 6 Block adjustment Gear The design structure of the gear with planetary stages allows a block adjustment to be additionally fitted for single contact adjustment from gear size 2. The final gear stage is therefore equipped with a black adjustment worm. All cam discs are adjusted together using this adjustment worm block adjustment (1).
Indicator disc/dial (optional) for the block adjustment display Fig. 7 Cam disc Dial, 5° separation Adjustment worm of the final cam disc Indicator Indicator disc (optional) By means of one of the indicator discs (3) attached to the back (B-side) of the GCLS, the block adjustment setting can be read from the dial (4) on the back panel.
The cam discs are named after the effective cam angle. For cam discs of series 51, this corresponds to the switching point angle on the switching point radius of the cam disc. Any cam angles (15° − 345°) can be supplied as a special design upon request. The usable revolutions enabled by a cam disc on a GCLS drive shaft, result in the following: ...
