a) Fastening:
Spot gearbox on the surface offering satisfactory rigidity. Mating surfaces ought to be machined and flat.
Mating surfaces should be within definite geometric tolerances (see guide). This is especially correct of flange-mounted gearboxes with splined hollow shafts.
In applications that involve large radial loads on the output end, flange mounting is proposed for some gearbox sizes as this mounting makes use of the double pilot diameters offered in these gearboxes.
Ensure the gearbox is appropriate for that necessary mounting position.
Use screws of resistance class eight.eight and more than to safe the gearbox. Torque up screws towards the figures
indicated in the pertinent tables.
With transmitted output torque greater than or equal 70% of the indicated M2max torque, and with
regular movement reversals, use screws with minimal resistance 10.9.
Some gearbox sizes could be fastened working with either screws or pins. Of pin seated while in the frame the gearboxes be at the very least one.five times pin diameter.
b) Connections
Safe the connection parts to gearbox input and output. Never tap them with hammers or very similar tools.
To insert these components, utilize the service screws and threaded holes presented on the shafts. Make sure you clean off any grease or protects in the shafts in advance of fitting any connection elements.
Fitting hydraulic motors.
Be cautious the O ring between motor flange and gearbox input flange when assembling. Install the
hydraulic motor prior to filling lube oil into the gearbox.
Connecting the hydraulic brake.
The hydraulic circuit must be this kind of to guarantee that brake is launched instants in advance of gearbox begins and applied soon after gearbox has stopped. Verify that stress inside the hydraulic line for brake release is at zero each time gearbox is stopped.
Course of rotation
Motors are linked on the suitable electric or hydraulic circuit based on their direction of rotation.
When executing these connections, keep in mind that all gearboxes, whether from the in-line or suitable angle design, possess the very same course of rotation each at input and output. For a lot more facts of the connection of electric and hydraulic motors, see appropriate sections in this catalogue.
