<p>The invention relates to a device and a method for testing the teeth of asymmetric gear wheels, intended to be employed in determining the maximal load force of a tooth of asymmetric gear wheel under static conditions in the stage of designing the gear wheel in the assembly of a reduction unit. According to the invention, the device is mounted on a materials testing machine (8) and comprises a base plate (1), a test specimen support (5), a fastening yoke (6), a test specimen (4), a rack support (2) and a rack (3). The teeth testing method, as claimed by the invention, has the following stages: manufacturing the test specimen (4), placing the device (7) into the materials testing machine (8), placing the test specimen (4) in the support (5), driving the device (7) for applying a stress on the tooth, measuring the variation of the tangential testing force Fand of the tooth deformation up to the moment of the breaking thereof, removing the used test specimen (4) from the device (7), removing the device (7) from the materials testing machine (8) and processing the obtained data.</p> |
