Abstract

The invention discloses a ring riveting device and a ring riveting method thereof. The ring riveting device is used for carrying out ring riveting on a combined gear. The ring riveting device comprises an upper die and a lower die, wherein the end surface of the upper die is provided with a plurality of riveting teeth, the lower die is provided with a die core hole, and shaft teeth of the combinedgear are accommodated in the die core hole for positioning. The axis of the upper die is aligned with the axis of the combined gear, the riveting teeth of the upper die rivet and press the end surfaces of sheet teeth from top to bottom, the riveting teeth rivet and press the peripheries of matching surfaces between the sheet teeth and the shaft teeth to form a plurality of riveting holes, the contact area of the matching positions between the sheet teeth and the shaft teeth is increased, the purpose of increasing axial sliding force is achieved, and the phenomenon that the matching positionsslip and lose efficacy under the stress use condition is avoided.

Description

technical field [0001] The invention relates to the technical field of gear processing, in particular to a ring riveting device and a ring riveting method. Background technique [0002] Due to the small fit between the piece teeth and the shaft teeth of the existing conventional combined gear, the phenomenon of slippage and failure of the fit will occur under the condition of force use, so that the combined gear cannot work normally. Contents of the invention [0003] In order to solve the above problems, the present invention provides a ring riveting device, which increases the matching position between the blade teeth and the shaft teeth by performing ring riveting processing on the outside of the matching position between the blade teeth and the shaft teeth, and solves the problem of force-bearing use. There will be a phenomenon of slipping failure of the matching position. [0004] Another object of the present invention is to provide a ring riveting method for the ab...
