  • Publication number: 20110017004
    Abstract: The invention relates to a method for setting the tooth face position of a gear wheel (2), which is non-positively connected to a double-skewed pinion shaft (1). A hydraulic press fit (4, 4a) is formed between the gear wheel (2) and pinion shaft (1) for relieving a non-positive connection of the gear wheel (2) shrink-fitted onto the pinion shaft (1). The setting is carried out by determining a tooth face apex point (A) of the double-skew of the pinion shaft (1). A radial plane (E) with a predetermined axial offset (AV) from the tooth face apex point (A) and a radial offset (RV) with respect to the tooth face apex point (A) are defined. The intersecting point (S) of a tooth face (11) of the gear wheel (2) must be located with the predetermined radial offset (RV) in the radial plane (E).
