Place gearbox on a surface providing adequate rigidity. Mating surfaces need to be machined and flat.
Mating surfaces need to be inside of definite geometric tolerances (see guide). This is certainly in particular true of flange-mounted gearboxes with splined hollow shafts.
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 for your required mounting position.
Use screws of resistance class 8.eight and in excess of to secure the gearbox. Torque up screws to your figures
indicated from the relevant tables.
With transmitted output torque better than or equal 70% on the indicated M2max torque, and with
frequent motion reversals, use screws with minimum resistance ten.9.
Some gearbox sizes is usually fastened making use of both screws or pins. Of pin seated within the frame the gearboxes be at least 1.5 instances pin diameter.
Secure the connection elements to gearbox input and output. Tend not to tap them with hammers or equivalent equipment.
To insert these parts, use the support screws and threaded holes supplied to the shafts. Be sure to clean off any grease or protects from the shafts just before fitting any connection components.
Fitting hydraulic motors.
Be careful the O ring amongst 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 ought to be such 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.
Path of rotation
Motors are linked towards the ideal electric or hydraulic circuit as outlined by their route of rotation.
When carrying out these connections, bear in mind that all gearboxes, no matter if within 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 electrical and hydraulic motors, see pertinent sections on this catalogue.
