Abstract
An arrangement performs a contact pattern test of bevel gears when they are produced. The arrangement includes a testing unit in connection with a machining apparatus, to which testing unit a finished bevel gear can be fastened to rotate around its axis so that the finished bevel gear and the other bevel gear which is being finished can be arranged into a rotating contact with each other so as to allow the contact pattern of the cogs to be checked.
Claims4
An arrangement for performing a contact pattern test of bevel gears which are to rotate in tooth contact when the machining of the bevel gears is carried out in a machining apparatus, which comprises a body, a machining unit and a fastening unit which are movable in relation to the body, which fastening unit can be turned around a vertical axis and onto which the bevel gear to be machined is to be mounted for the duration of the machining, the arrangement further comprising a testing unit in connection with the machining apparatus, to which testing unit one of the bevel gears or the bevel gear set can be fastened after its machining so that it can rotate around its rotational axis, the testing unit and the fastening unit being movable so that after the latter bevel gear of the bevel gear set has been machined, said units can be moved into such a position in relation to each other that the position of the bevel gears enables the contact pattern test without unfastening the latter bevel gear from the fastening unit.
