Problems solved by technology

A further disadvantage is that the welding processes with welded electrodes that have hitherto been used in the manufacture of hybrid large transmission gears are highly manual and extremely time-consuming, so they can only be used economically in small batches in production
The determination of process data in series production is not yet state-of-the-art and can only be documented by means of subsequent quality control

Embodiment Construction

[0070] figure 1 with figure 2 A large transmission gear 1 according to a first embodiment of the invention is shown, having an outer diameter of 600 mm or more. The large transmission gear is a hybrid gear, which is produced from a number of individual components, namely a substantially cylindrical hub 2, a disk wheel 3 and a case-hardened toothed ring 4, which is indicated by arrow A The marked positions are welded to each other.

[0071] At least one disk wheel 3 is provided with an eccentrically arranged recess 5 . The recesses each have a different shape and are arranged asymmetrically distributed on at least one disc wheel 3, as in figure 1 as shown in.

[0072] The large transmission gear 1 is manufactured as follows. In a first step the individual components, namely the hub 2, the disc wheel 3 and the toothed ring 4 are provided. A mechanical soft machining of the component is achieved in a subsequent step. The hub 2 is turned here. The ring gear 4 is then equi...

Abstract

The invention relates to a method for producing a face gear (1; 10; 32; 39) consisting of a plurality of individual components, the method having the following steps: a) providing a single component comprising at least one hub (2; 11 ; 33; 40), disc wheels (3; 12, 13; 34, 35; 41, 42) and ring gears (4; 14; 36; 43), b) at least partially machined individual components, c) connecting the individual components using a welding process, d) hardening at least one toothed ring (4; 14; 36; 43), e) hard machining at least one toothed ring (4; 14; 36; 43) and f) in use In the case of a nitric acid etchant corrosion process, a burnout grinding test is carried out, characterized in that, before step f), the sealing material (8; 24; 38) resistant to nitric acid is used to realize the Sealing of the rear gap (6; 23; 37) present in the region of the formed weld seam.

Description

technical field [0001] The invention relates to a method for producing a face gear consisting of individual components. Background technique [0002] The basic purpose of a gear train is to achieve the highest possible torque transmission at a desired speed. On the one hand, an application-dependent safety of the individual transmission components must be achieved here. On the other hand, it must be possible to manufacture the structure economically. The key components here are meshed components such as ring gears, planetary gears, sun gears, pinion shafts and spur gears, the latter being utilized to the greatest extent possible within the framework of their toothing due to their diameter and weight. For this purpose it is necessary in all cases to produce the spur gears from high-value gear steels with a low probability of error and a high degree of purity. [0003] In order to achieve the necessary edge strength and root strength, in most cases at least the area of ​​th...
