ANALYSIS ON THE AXLES

The axles are the interface between our wheels and the aircraft on which they are installed.
In our catalogue there are many types of axles, all those that our customers have requested us over the years; we can easier produce new models based on the customer’s design, even for experimental aircraft
Our axles are of two types: round axles and 4-holes axles.
to explain the axle we can divided it into two parts: the first must interface with the aircraft, the second with our wheels.
The round axles on the side towards the aircraft have a round body that has to inserted directly into the leg; they are stopped with a transversal bolt to fixing the axle and preventing rotation during braking; they are provided with a welded 3-holes flange the brake caliper is fixed to. The position of the flange is designed to obtain the correct axial positioning of the caliper, whether it is floating aluminum caliper or fixed magnesium caliper.
Almost all models can be special fitted for the installation of the wheel cover or skis.
The 4-hole axles have a flange with 4 holes to place the bolts in, to tighten the carriage leg, the axle and pincer together.
In most models the interaxes of the holes are the same: the interchangeability help us by reducing waiting times and costs.
the self-locking ring does not have a setback on the axle but only on the bearing, so, an incorrect tightening can cause damage to the bearings.

To avoid problems, we recommend placing a special spacer piece between the bearing and the self-locking ring: our spacer part number 0100101205 rev1.
Explanation:
an unaligned landing can cause an axial thrust moves from the ground to the tire, and then to the semi-rim, which transfers it to the hub and finally to the bearing.

The bearing that receive and hold the thrust is the one opposed to the direction of the thrust: it is contained between two opposite shoulders: outside the hub, inside the axle.
The other bearing is not affected by any axial thrust, as it could slip out of the hub, so the use of the inner spacer does not help to distribute the load between the two bearings, it is used only to avoid overloading the bearings during the closing of the ring.
If in the axle is fitted the containment ring there is no risk of breakage: it’s in contact with the axle and the distance between the bearings is guaranteed.
To facilitate the installation of the self-locking ring nut (when present) we recommend the purchase of the corresponding key: it facilitates the assembly / disassembly operation and avoids damaging. So light to be picked up on board the aircraft.
