Definitions
- the invention relates to a grinding wheel, preferably for grinding gears, is provided with a bore serving for their attachment and with a reinforcing layer, and a method for strengthening the grinding wheel.
- Such grinding wheels are used, for example, in the machining of gears for car transmissions.
- it is necessary to strives to steadily increase the cutting speeds during continuous generating grinding.
- safety standards must be adhered to, according to which the permissible cutting speed must be in a specific relationship to the blasting speed of the grinding wheel.
- the invention is based on the object to provide a grinding wheel of the type mentioned that an increase in the blasting speed during operation of the grinding wheel is made possible.
- both a bore lining the bore and this reinforcing layer are formed in the grinding wheel pores by at least one cast-in plastic.
- potting compound a 2-component polyurethane system has been found to be particularly suitable.
- the grinding wheel according to the invention is set in rotation with a preferably horizontally oriented rotation axis and, for example, 400 rpm (revolutions per minute), a certain amount of potting compound is poured into the bore, whereby by adjusting the spin speed and / or the amount, the degree of liquid and the curing time of the potting compound used, the penetration depth of the adhesive into the grinding wheel and the thickness of the reinforcing ring can be set within certain limits.
- Fig. 1 shows an arrangement for reinforcing a grinding wheel with a
- Fig. 2 is a side view of the grinding wheel.
- FIG. 1 shows a grinding wheel 1 of porous ceramic material, wherein it is preferably made of corundum. Of course, instead of corundum other similarly porous structured ceramic materials may be considered.
- the grinding wheel 1 is provided with a bore 2 in particular for its attachment to a spindle of a machine tool.
- At least one cast-in plastic material forms both a ring 2a lining the bore 2 and this reinforcing layer 2b in the grinding wheel pores V.
- the grinding wheel is made of an open to highly porous structure, advantageously with a porosity of over 50 percent by volume.
- a potting compound of a 2-component polyurethane system which is particularly suitable both in terms of its physical properties and because of its economy potting compound for producing the ring 2a and for filling the disc pores V in Area of the annular reinforcing layer 2b.
- other suitable casting compounds can be used.
- the potting compound is poured into the bore 2 of the grinding wheel 1 by means of a casting device, of which only one supply nozzle 5 is currently shown, which guides the potting compound into the region of the bore 2.
- a casting device of which only one supply nozzle 5 is currently shown, which guides the potting compound into the region of the bore 2.
- the grinding wheel 1 To produce the ring 2 a surrounding the bore 2 as well as the reinforcing layer 2 b in the grinding wheel pores V of the grinding wheel 1, it is rotated about the horizontally oriented axis of rotation 6 by a drive, not shown, while a certain one is provided by the casting device with the feed nozzle 5 Quantity potting compound is supplied.
- the grinding wheel 1 rotates at a speed of, for example, 400 rpm (revolutions per minute), whereby the cast-in casting compound penetrates into the pores 1 'of the grinding wheel 1 due to the then acting centrifugal force and bonds with its ceramic material.
- the achievable penetration depth 4 and also the wall thickness 3 of the ring 2a are dependent on the spin speed and the cast amount, as well as the degree of liquid and the curing time of the potting compound used. By varying these sizes, the wall thickness 3 or penetration depth of the potting compound and the thickness of the reinforcing layer 2b can be regulated within certain limits.
- the cast-in plastic for the formation of the ring and the reinforcing layer in the grinding wheel pores by a layered pouring with different materials of Verguss, Adhesive masses may be formed.
