Definitions
- the invention relates to a deep rolling head of a deep rolling tool according to the preamble of the first claim.
- Deep rolling roller heads of this type are known. For example, from WO 03/090972 A1 a
- a deep rolling roller head of a deep rolling tool for deep rolling of radii or punctures on the main and thrust bearing pin of crankshafts known with a housing in which one or two fixed rollers are laterally spaced from each other with little play in a roller cage rotatably guided.
- the roller cage is fastened on the underside of the housing facing the crankshaft with pins which respectively support the roller cage on its end faces facing away from the deep-rolling rollers and at the same time guide them laterally.
- the housing of the deep rolling roller head is provided on its side facing the crankshaft bottom at both ends thereof each with a projection for supporting the roller cage. Pins as fastening and guiding members for the roller cage are provided and engage in the roller cage.
- the end face adjoining the underside has a predetermined first distance to the middle over a portion of its length.
- the associated short leg is supported by a stop on its inside on the portion of the housing.
- the roller cage supporting the end face of the associated long leg has a predetermined second distance from the section.
- the deep rolling roller head of a deep rolling tool is known, as used for deep rolling of radii or punctures on the main and stroke bearing journals of crankshafts with a housing in which one or two deep rolling rollers are spaced laterally apart with little play each guided in two roller cages are loosely rotatable.
- the roller cages are mounted on the crankshaft facing the front side of the housing with holders which support the roller cages each on their side facing away from the fixed rollers ends and at the same time lead laterally.
- the housing is provided on its side facing the crankshaft at both ends thereof each with a projection for supporting one of the two roller cages.
- An attachment and management body for each Roller cage is provided and engages in the roller cage, wherein it can be attached to one of the projections of the housing at the same time.
- the well-known deep rolling roller heads have in common that for mounting the roller cages close tolerances must be met. Narrow tolerances increase the cost price of the tool. For this reason, the present invention is based on the task of reducing the number of pieces or sections of the deep rolling roller head, which must be made to hold the roller cages within low manufacturing tolerances. At the same time it should be possible to continue to use organs, such as the L-shaped holder, as they are known and in use. Finally, it should be possible with this so to be created innovation to remedy the occurring at the direction of rotation of the crankshaft roller cage occurring wear by simple means.
- this object is achieved in that the direction of rotation of the crankshaft remote from the end face of the housing of the deep rolling roller head has a projection on which one of the roller cages with its front side is supported, which lies opposite the end face, wherein the deep rolling roller is guided.
- a known L-shaped holder is provided, which is with respect to the housing and lockable and at the end of the long leg of the other roller cage of the deep rolling tool with its front side supported, which in turn is the end face, in which the deep rolling roller is guided.
- an offset with which the deep rolling against the direction of rotation of the crankshaft relative to the longitudinal center of the housing of the deep rolling roller head can be realized without any special effort.
- the offset is between 0.1 and 1 mm and is preferably 0.2 mm.
- the single figure shows approximately true to scale a deep rolling head in the side view.
- the deep rolling roller head 1 of a deep rolling tool for deep rolling by means of deep rolling rollers 2 of radii or recesses 3, which are represented in the present case by a broken circular line, to the main or crankpins 4 a crankshaft (not shown) while the crankshaft rotates in a rotational direction 5, has a prismatic, flat, approximately rectangular housing 6.
- the two roller cages 8 and 9 each have a first end face 10 and 11 which have a mutual distance 12 from each other and at the same time a distance 13 and 14 to the longitudinal center 15 of the housing 6.
- end faces 10 and 11 recesses 16 are provided, wherein the deep rolling rollers 2 loosely guided.
- first end faces 10 and 11 opposite second end faces 17 and 18 of the roller cages 8 and 9, these are based on parts of the housing 6 or on organs, which are slidably mounted on the housing 6.
- the direction of rotation 5 of the crankshaft facing away from section 19 of the end face 7 of the housing 6 has a projection 20 on which the roller cage 8 is supported with its second end face 17.
- an L-shaped holder 22 is provided, as it is known per se from the prior art.
- the L-shaped holder 22 is with respect to the Housing 6 via screws 23 and 24 and lockable.
- the other roller cage 9 is supported with its second end face 18 from.
- the longitudinal center 15 of the housing 6 and the center of rotation 27 of the bearing journal 4 of the crankshaft lie in one and the same plane. Compared to this plane, the center of rotation of the deep rolling roller 2 is displaced by an offset 28 against the direction of rotation 5 of the crankshaft.
- the offset 28 is between 0.1 and 1 mm, preferably 0.2 mm.
- the projection 20 of the end face 7 of the housing 6 has a support surface 29, on which the second end face 17 of the roller cage 8 abuts and is supported.
- the support surface 29 has a distance 30 from the longitudinal center 15 of the housing 6, which is greater by the offset 28 than the distance that has the outer end 25 of the long leg 26 of the L-shaped holder 22 from the longitudinal center 15 of the housing 6. It is assumed that the two roller cages 8 and 9 each have the same dimensions.
