Description

Technical Field

[0001] The utility model relates to the field of transmission processing, in particular to a transmission friction plate tooth profile alignment and centering device. Background Art

[0002] When assembling the clutch assembly of an automatic transmission, the steel plates and friction plates are alternately stacked in the clutch outer hub. Since there is no clamping force between the steel plates and the friction plates at this time, the friction plates can rotate and move freely in the radial direction. After completing the stacking of the steel plates and the friction plates and installing the retaining springs, the friction plate tooth-shaped mating parts need to be installed into the inner tooth profile of the friction plates. During the alternating stacking process, the axis of the friction plates usually deviates from the axis of the outer hub, and the inner tooth profiles of the friction plates are easily misaligned with each other. In addition, the friction plate tooth-shaped mating parts have been centered by the shaft when they are installed, so if the friction plates are not centered, the tooth-shaped mating parts will be blocked by the friction plates and cannot be installed. Before installing the friction plate tooth-shaped mating parts, the inner tooth profile of the friction plates needs to be aligned and centered.
