Abstract

The invention relates to a bell housing (101) having a first region (103) for securing in a nacelle of a wind turbine, a second region (105) for receiving a gear mechanism, and a wall (107); said wall(107) connecting the first region (103) and the second region (105) together. The wall (107) is provided with at least two recesses (109).

Description

technical field [0001] The invention relates to a transmission cover according to the preamble of claim 1 . Background technique [0002] For fastening the transmission in the nacelle of the wind turbine, torque struts and transmission housings are known from the prior art. The transmission cover is usually provided with ribs for added rigidity. But ribs can cause problems when casting. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a transmission cover which does not have the inherent disadvantages of the solutions known from the prior art. In particular, the transmission cover should be easily castable. And this should not sacrifice rigidity. It is also an object of the invention to improve the vibration behavior of the gear housing. [0004] This object is solved by a transmission cover according to claim 1 . Preferred refinements follow from the claims. [0005] The transmission cover has a first region, a second region and a...
