Installation of Track Drive Planetary Gearbox

Observing a few rules for correct installation is essential to the reliable and proper operation of the gearbox or gear motor.

The rules set out here are intended as a preliminary guide to selecting a gearbox or gear motor. For effective and proper installation, follow the instructions given in the installation, and use the maintenance manual for the gearbox available from our sales department.

Following is a brief outline of installation rules:

a) Fastening:

Place gearbox on a surface providing adequate rigidity. Mating surfaces should be machined and flat.

Mating surfaces must be within definite geometric tolerances. This is especially true of

flange-mounted gearboxes with splined hollow shafts.

In applications that involve high radial loads at the output end, flange mounting is recommended for some gearbox sizes as this mounting makes use of the double pilot diameters provided in these gearboxes.

Make sure the gearbox is suitable for the required mounting position.

Use screws of resistance class 8.8 and over to secure the gearbox. Torque up screws to the figures indicated in the relevant tables.

With transmitted output torque greater than or equal to 70% of the indicated M2max torque, and with frequent movement reversals, use screws with minimum resistance 10.9.

Some gearbox sizes can be fastened using either screws or pins. pin seated in the frame of the gearboxes be at least 1.5 times pin diameter.

b) Connections

Secure the connection parts to gearbox input and output. Do not tap them with hammers or similar tools.

To insert these parts, use the service screws and threaded holes provided on the shafts. Be sure to clean off

any grease or protect from the shafts before fitting any connection parts.

Fitting hydraulic motors.

Be careful the O ring between motor flange and gearbox input flange when assembling. Install the hydraulic motor before filling lube oil into the gearbox.

Connecting the hydraulic brake.

The hydraulic circuit should be such to ensure that brake is released instantly before gearbox starts and applied after gearbox has stopped. Check that pressure in the hydraulic line for brake release is at zero whenever the gearbox is stopped.

Direction of rotation

Motors are connected to the suitable electric or hydraulic circuit according to their direction of rotation.

When performing these connections, bear in mind that all gearboxes, whether in the in-line or right-angle design, have the same direction of rotation both at input and output. For more details of the connection of electric and hydraulic motors, see relevant sections in this catalog.

c) Painting

Painted with antioxidant water primer in the color red. Mating surfaces are not painted. The final coat is to be applied by the customer. Before painting, protect the seal rings installed on the shafts. Contact with paint may deteriorate the seals with subsequent oil leakage.

d) Lubrication

Before start-up, fill the gearbox with the recommended lube oil up to the correct level. The level is checked through the suitable plug or sight glass provided on each gearbox, depending on the designated mounting position.
