Abstract

The invention relates to a fixing device (10), in particular to a bellows fixing device, comprising a convex spigot section (14) and a concave spigot section (16) matched with the convex spigot section, and relates to the used The method for fixing the bellows to the universal joint housing and / or shaft by the fixing device described above. In order to improve the closure properties of the fastening device, the fastening device according to the invention is provided with an inner recessed area (36).

Description

technical field [0001] The invention relates to a fixing device, especially a bellows fixing device, which comprises a convex spigot section, a concave spigot section matched with the convex spigot section, and an inner notch area installed on the convex spigot section , and relates to a method for fixing a bellows to a universal joint housing and / or a shaft with said fixing device. Background technique [0002] Bellows fixtures are known from elastic materials, in particular pleated bellows and rolled bellows. Therefore, sometimes overlapping fixing straps can be used, and the clamping effect can be achieved by tightening the two free ends of the fixing straps by an appropriate method. However, the portion of the pleated bellows which is in contact with the free end of the fixing band is easily damaged, and furthermore, the fixing band requires a large installation space. Therefore, some endless loop closure snap rings have been suggested in the past. The diameter of the...
