Definitions
- the invention is based on the object of making the lubricant guide and supply safer in order to maintain the required uniform, uninterrupted flow of lubricant.
- the object is achieved according to the invention in that the upper flange and the lower flange form a lubrication gap for liquid lubricant which is delimited on both sides and that the lubrication gap has a labyrinthine shape in the flow direction before the lubricant emerges.
- the advantage is a constant lubricant flow, which keeps contaminants away more easily and with which contaminants are less likely to adhere. remaining Contamination is easier to remove from the lubricant outlet.
- the labyrinth-like course is formed by a ring recess trapezoidal on one side with a flank in a lubricant cover and a rectangular projection protruding into it on a lubricant flange. Metal or slag splashes can only reach the labyrinth flank and are therefore easier to remove.
- a further improvement is achieved in that the upper flange in the area of the labyrinth is made of a material that is resistant to heat and temperature changes. This also prevents the sticking of liquid metal or slag splashes. Ceramic materials in particular are used for this.
- Fig. 4 is a front view of the outlet slot with alternative inserts made of non-steel materials.
- the upper flange 3 and the lower flange 4 are made of steel as carriers of the rings 17.
- the lubricant 7 consists of casting oil of natural or synthetic origin or from a mixture of one of these oils with a low-friction, heat-resistant material such as graphite, casting powder and the like. Like. LIST OF REFERENCE NUMBERS
