Wheel of a chassis for elaen parked on carriers Transformer with a cycling shoe underneath the wheel

The innovation is aimed at a wheel one Chassis * for a transformer placed on girders with a wheel shoe underneath the wheel, this having a flat base and a curved inner surface facing the wheel.

Medium-sized transformers, such as those used for converting electricity fed into the factory, Workshops or groups of chewers are used to set them up with a simple, equipped with four wheels mounted in a frame. With help the wheels can then be relatively heavy

on the transformer house or some other substructure previously installed, mostly walled, girders consisting of T- or I-girders can be parked. After that, yours will be usually from the deodorant surface perpendicular or obliquely protruding, isolated so-called · 'horns on the inlet and Derivatives connected.

In operation arise in a transformer as a result of the electromotive force acting in it Forces vibrations, which are expressed in an audible humming and spread over the wheels to the Beams on which they are placed and transferred from these to the masonry. this in turn brings both a noise nuisance and the risk of the wheels rolling away on their parking racks with himself. While the vibrations transmitted to the masonry can cause cracks in it and vibration noises can be transmitted to other rooms via the masonry, a path the wheels roll, even if only over a short distance, to loosen the line connections on the »insulated horns of the transformer that protrude upwards.

Therefore, the innovation is based on the task of rolling the wheels of a chassis of a transformer in operation and
