Housing for winning machines used in underground mining, in particular drum shearers

摘要

The invention relates to a housing 6 for winning machines used in underground mining, in particular drum shearers 1. This housing 6 serves to accommodate components from power electronics, for example thyristors, chokes or transformers 7, and consists of a cylindrical casing 8 provided with a flange 9 at one end. A bush 10 is pushed into the casing bore in a closing manner, the fluid passage 12 of which, running in the bush periphery, is connected to a feed and discharge line 13. The push-in support 16 holding the components is located inside the bush bore. The support 16 is provided with two shell-shaped cooling bodies 17 extending over the length of the bush bore. They are located on opposite sides of the support 16, where they bear with their peripheral surface in a closing manner against the bore wall of the bush 10 and turn their arched inner surface, provided with cooling ribs 19, towards the support 16.
