The Beveloid gear is a helical cylindrical gear with non-parallel axes but inclined up to 15°, for this reason it is very useful to apply them when a slight inclination of the axis of use is required. We typically recommend it for the marine sector when space needs to be greatly optimised.
GSI deals with developing projects with relatively small beveloids. Therefore, it is faced with situations where it is important to have a lean structure. Over time and also in the face of various studies it has been possible to reach the conclusion that it is better to house the engine horizontally. From here it follows that the shaft that connects the propeller comes out not perpendicular but slightly inclined.
The turning point is given by the possibility of having inclined axes which allow the output shaft of the marine inverter to carry out its work correctly.
Some technical data on the management of the beveloid
Surely, it is not a piece suitable to be machined without experience on both the technical, production and control sides. The first aspect of study to get to the realization is perhaps the most important and complex phase to allow not to make mistakes during production. Here, the pieces are built by moving the horizontal axis of the hobbing or tooth grinding machine with a motion synchronized with the vertical axis of the machine. Finally, as regards the control of these pieces, the verification of the contact is assumed. So a simple check with the involute gauge is not enough. This is because, given its geometry, the Beveloid has a helix distorted by the inclination of the characteristic diameters of the gear. Only the contact test can determine the correct profile to build.
Due to its complexity, the beveloid gear therefore requires strong experience both on the technical side and on the manufacturing side.
