BEVEL GEARBOX

R SERIES CUBIC BEVEL GEARBOX

The bevel gearbox is a system designed to transmit a rotary motion of power to axes perpendicular to each other.

GOOD REASONS TO USE R QUICKDRAWS

Let’s see the main features of R cubic bevel gearboxes:

Cubic shape for universal, interchangeable mounting on any machine
Available in eight sizes (54-86-110-134-166-200-250-350)
They stand out for the lightness of the crankcase, which for the first seven sizes – except for the 350 which is made of cast iron – are made of aluminum alloy
Gleason bevel gears, in Nikel-Chrome steel, which ensure maximum exhaust capacity; To ensure long life, they are surface treated with case-hardening.
Five ratios of reduction or multiplies. 1:1 – 1:1,5 – 1:2 – 1:3 – 1:4
carbon steel shafts at 80Kg/mmc
three standard types of grips: male shafts, cavities with traction by tongue or grooved profile of type UNI 8953 or dragging by means of shrink discs
Male shafts ground to H7 tolerance and drilled shafts for tongues or shrink fit ground to H7 tolerance
tapered roller bearings – except for size 54 which is fitted with deep-groove ball bearings
sealing rings in nitrile compound, on request in Viton, Silicone, Teflon and more
oil lubrication. Size 54 is lubricated with permanent synthetic grease

SIZING OF THE BEVEL GEARBOX

The type of angular gearbox is identified according to the handling needs to be met. It is important to already have an idea of the system diagram in order to correctly identify the power flows.

First of all, it is essential to identify power, number of revolutions, torques to be transmitted, torque and, PTO, choosing between male shafts, hollow shafts with tongue, UNI 8953 splined profile or DIN mouse, shrink discs or hexagonal cavities…

It is also very important to take into account the heavy use of the bevel gearbox. And in particular, pay attention to:
