- the application is effected by means of an ultrasonic sonotrode, which on the one hand lowers the slide wedge 31a axially inwards by mechanical pressure.
- the inclined surfaces 26a and 36a slide against one another, guided by the ribs 34a and the grooves 24a, while at the same time radially inside the second support surface 37a to the shoulder 8 'of the second fitting part 8 applies, supported by the first support surface 27a radially outward.
- the ultrasonic sonotrode softens the material of the ribs 34a after complete clearance compensation and thus fills the grooves 24a. After curing of the material both wedges 21a and 31a are firmly welded together and thus remain in the position in which the game is completely balanced.
- the dimensions of the slider 15 are chosen so that even large radial tolerances of the two fitting parts 7 and 8, i. large distances between the second support surface 37a and the paragraph 8 ', aus ⁇ can be compensated, so that in most cases there is an overcompensation of the radial tolerances.
- the ultrasonic welding ensures that the wedges 21a and 31a are connected and held in position with complete clearance compensation.
- the ultrasound sonotrode gives way to the entire material of the two wedges 21a and 31a until the gaps to the fitting parts 7 and 8 are filled, adapting to the individually existing clearance and compensation of the tolerances. It is advantageous if the two wedges 21a and 31a have cavities into which excess material can evade.
