Embodiment Construction

[0014] Transmissions configured as conical spur gears for driving in figure 2 The work machine 11 is only partially shown in FIG. The transmission comprises an output stage in the form of a ring gear stage and one or more transmission input stages which will be described below. The working machine 11 is in this case a ball mill, on the cylindrical circumference of which a toothed ring 10 surrounding the ball mill is fastened. The invention can also be used in other working machines, such as crushers, tube mills, mixing drums or rotary kilns.

[0015] for housing in figure 2 The transmission housing 1 of the transmission shown in the figure 1 Consists of the first housing part 2 at the front. In the rear area of ​​the transmission housing 1 , the second housing part 3 with the protruding flange bushing 5 is connected to the first housing part 2 .

[0016] The first housing part 2 has a smaller diameter in the upper region 6 than in the lower region 7 and a greater height...

Abstract

The invention relates to a spur gear for driving a gear ring on a work machine having the features of the preamble of Claim 1. A spur gear, in particular a bevel spur gear having one or more gear stages for driving a work machine (11), which is enclosed by a gear ring (10), comprises a gear housing (1), which receives the gear stages, and contains an adjustably movable pinion (9), which is situated on an output shaft (26) of an output stage, and engages with the gear ring (10). The gear housing (1) comprises a first stiff housing part (2) and a second rigid housing part (3). The first housing part (2) encloses the output stage having the output shaft (26) and the adjustably movable pinion (9) and has side walls (19), which project beyond the gear (1) and rest on the foundation (23). The second housing part (3) is fastened on a front side on the first housing part (2) without contact with the foundation (23).

Description

technical field [0001] The invention relates to a spur gear transmission for driving a toothed ring on a working machine having the features stated in the preamble of claim 1 . Background technique [0002] The known ring gear drive drives the working machine especially in the upper power range. In this case, the axis of the working machine extends mainly in a vertical or horizontal direction. Such drives are found, for example, in ball mills, mixing drums, crushers, tube mills or rotary kilns. A special feature of this machine tool is the large toothed ring mounted directly on the machine tool, which is located spatially close to the actual machining process. The ring gear often forms together with other transmission stages a drive train for converting the drive power of the electric motor. In this case, the other transmission stages are located in their own transmission housing, which is inserted into the drive train via a solid flange connection or precisely aligned on...
