In applications that involve high radial loads at the output end, flange mounting is advisable for some gearbox sizes as this mounting can make utilization of the double pilot diameters supplied in these gearboxes.
Make sure the gearbox is suitable to the required mounting position.
Use screws of resistance class 8.eight and over to secure the gearbox. Torque up screws to the figures
indicated from the related tables.
With transmitted output torque better than or equal 70% with the indicated M2max torque, and with
frequent motion reversals, use screws with minimum resistance ten.9.
Some gearbox sizes can be fastened employing either screws or pins. Of pin seated within the frame the gearboxes be at least 1.5 instances pin diameter.
b) Connections
Secure the connection elements to gearbox input and output. Tend not to tap them with hammers or equivalent equipment.
To insert these parts, make use of the support screws and threaded holes offered to the shafts. Be sure to clean off any grease or protects from the shafts ahead of fitting any connection components.
Fitting hydraulic motors.
Be careful the O ring involving motor flange and gearbox input flange when assembling. Set up the
hydraulic motor in advance of filling lube oil to the gearbox.
Connecting the hydraulic brake.
The hydraulic circuit needs to be this kind of to make certain that brake is released instants just before gearbox starts and applied following gearbox has stopped. Test that pressure in the hydraulic line for brake release is at zero every time gearbox is stopped.
Route of rotation
Motors are linked for the ideal electric or hydraulic circuit according to their route of rotation.
When carrying out these connections, bear in mind that all gearboxes, no matter if inside the in-line or proper angle layout, possess the exact same route of rotation both at input and output. For more specifics with the connection of electric and hydraulic motors, see pertinent sections on this catalogue.
