Definitions
- the invention relates to a deep-rolling roller head of a deep-rolling tool for deep-rolling radii or recesses on the main and pin bearings of crankshafts with a housing in which one or two deep-rolling rollers are spaced apart from one another, corresponding to the axial width of the respective bearing pin, with little play in two Roller cages are loosely rotatable and the roller cages are fastened on the end of the housing facing the crankshaft with holders which support the roller cages on their end faces facing away from the deep-rolling rollers and at the same time guide them laterally.
- Deep rolling roller heads of this type are known, for example, from the publications mentioned below:
- the known deep rolling roller heads have in common that the roller cages are each attached to the housing of the deep rolling roller head with L-shaped holders. With the help of the holder, the roller cages can be brought into a predetermined position and fixed to the deep rolling roller head. It is provided that the deep rolling rollers in the respective roller cages can be loosely rotated with little play. This game is usually about 0.2 mm. In addition, it is provided that the deep-rolling rollers have an offset of approximately 0.2 mm from the center of the housing of the deep-rolling roller head, around which a guide roller for the deep-rolling rollers rotates, on which the deep-rolling rollers are supported with respect to the crankshaft. In addition, the deep rolling rollers in the deep rolling roller head also have an expansion in the axial direction.
- the exact, i.e. The predefined position of the deep rolling rollers in the deep rolling roller head is decisive for their service life. Despite precise adjustment, wear occurs, which increases the play between the deep rolling rollers and the roller cages during the use of the deep rolling tool. From this it can be seen that the precise setting of the deep rolling rollers in the deep rolling roller head is of particular importance.
- the setting is made via the L-shaped holder for the roller cages.
- there are setting gauges for this setting but it is also customary to have the setting carried out by hand by a skilled specialist.
- the service life of the deep rolling rollers and roller cages is significantly influenced by the skill of the hiring specialist.
- setting the deep rolling rollers is a lengthy task, which requires a lot of work.
- the object of the present invention is to improve a deep rolling roller head in such a way that that an exact setting of the deep rolling rollers is possible without special skill or great effort in working time. It should also be possible to compensate for the wear that occurs on the roller cages. At the same time, the service life of the deep rolling rollers and roller cages and the quality of the rolled product should be improved. After all, the improvement should be simple and inexpensive and should also be able to be carried out by less experienced specialists with the required precision.
- the object is achieved by a novel design of the housing of the deep rolling roller head, in that the housing on its end facing the crankshaft receives a projection on each end of the end for supporting one of the two roller cages and a fastening and guide element for the respective roller cage is provided which engages in the roller cage and can be attached to the projection of the housing.
- one or two spacers in the ends of the housing of the deep-rolling roller head can be moved in the direction of the deep-rolling rollers and made adjustable and lockable in different positions with the help of a fine adjustment. In this case, the wear of the roller cages, as soon as it becomes noticeable, will be compensated for from time to time by adjusting the spacer (s).
- the new design of the housing of the deep rolling roller head does not change anything on the roller cages themselves. They still have a longitudinal groove on their underside facing the crankshaft, via which they are held on the housing by a suitable organ and guided laterally.
- the organ consists of a simple, flat tab, one end of which is screwed onto the projection of the housing and the other, free end of which protrudes into the groove on the underside of the roller cage.
- a single tab can also be provided, which bridges both roller cages and is detachably screwed with its two ends to the respective projection of the housing of the deep rolling roller head.
- the spacer insertable between the projection and the respective roller cage can serve, as already described, to produce the offset of the deep-rolling roller, but also to compensate for the wear of the roller cage to a certain extent.
- Fig. 1 a deep rolling roller head in side view
- Fig. 3 shows another deep rolling roller head with a partially sectioned side view
- Fig. 4 shows a longitudinal section through the deep rolling roller head of Fig. 3 along the line IV - IV.
- the deep rolling roller head 1 has an approximately rectangular, flat housing 2.
- the lower end face 3 of the housing 2 faces the crankshaft 21, of which FIG. 1 shows the section through any main bearing, the bearing journals of which are delimited laterally by radii or recesses 22 , Deep rolling rollers 4 engage in these radii or recesses 22, which in turn are rotatably mounted with little play between two adjacent roller cages 5 and 6.
- the play between the deep rolling roller 4 and the two roller cages 5 and 6 is in each case approximately 0.1 mm to 0.5 mm, preferably 0.2 mm.
- the end faces 8 of the two roller cages 5 and 6 have a lateral distance from one another and also a lateral distance from the center of rotation 7 of the housing 2.
- roller cages 5 and 6 each have groove-shaped recesses 9, in which a deep rolling roller 4 is rotatably guided on two opposite sides on the circumference of their body.
- FIG. 2 shows the two recesses 9 on the end face 8 of a roller cage 5.
- the inclined position of the two recesses 9, which can be seen in FIG. 2, corresponds at the same time to the inclined position of the deep-rolling rollers 4 in the deep-rolling roller head 1.
- roller cages 5 and 6 are supported on corresponding projections 11 and 12.
- roller cages 5 and 6 each jump out on the underside 3 of the housing 2 and open a recess 13 between them, in which the two roller cages 5 and 6 and the deep-rolling rollers 4 are accommodated.
- the Roller cages 5 and 6 are not connected to the housing 2 or its projections 11 and 12. They are loosely supported and guided in the recess 13 between the two projections 11 and 12.
- the roller cages 5 and 6 are supported with their rear end faces 10 in each case on corresponding surfaces 14 of the projections 11 and 12.
- Tabs 15 are provided to hold the roller cages 5 and 6 on the housing 2.
- the tabs 15 consist of flat iron of small length and width, and are each detachably connected to the respective projection 11 or 12 of the housing 2 by means of screws 16.
- the front, freely projecting end of the two tabs 15 engages in a groove 18, which is provided on the underside 19 of the roller cage 5 and 6 (Fig. 2).
- a single tab can also be provided, which extends over the two roller cages 5 and 6 and bridges the distance between their end faces 8.
- a spacer 20 is inserted between two adjacent surfaces 10 and 14, which itself has only a small thickness between 0.1 mm and 0.5 mm, preferably 0.2 mm.
- the spacer 20 also serves to adjust the center of rotation of the deep-rolling roller 4 relative to the center of rotation 7 of the housing 2 by a small amount, which is also between 0.1 mm and 0.5 mm, preferably 0.2 mm.
- a pin can also be provided, which secures the holding and guiding of the respective roller cage 5 and 6 on the projection 11 and 12 of the housing 2.
- the spacer 23 of FIG. 3 is a prismatic body of substantially greater axial length than the thickness of the spacer 20 of FIG. 1. 3 shows only a single spacer 23, which supports the adjacent roller cage 5 on its rear face 10. Analogously, a similar spacer corresponding to the spacer 23 can also be assigned to the roller cage 6.
- the spacer 23 is guided on two cylindrical pins 24 which engage in bores 26 within the projection 11 of the housing 2 at a mutual distance 25 from one another.
- the pins 24 are parts of the spacer 23 and firmly and non-detachably connected to this.
- the distance 25 creates space for the engagement of the screw 16 for the tab 15 in the projection 11.
- the two bores 26 are each closed by grub screws 28, the position of which within the bores 26 can be adjusted from the end 27.
- the spacer 23 with its two pins 24 is supported on the grub screws 28.
- the exact position of the spacer 23 and thus the position of the roller cage 5 on the housing 2 of the deep rolling roller head 1 is set.
- the two grub screws 28 are fixed by a screw 29 which acts on the two grub screws 28 via a soft washer 30.
- the position of the spacer 23 and thus the position of the roller cages 5 and 6 to the deep rolling rollers 4 is adjusted as required to the wear of the roller cages 5 and 6 by adjusting the grub screws 28 and locking the screw 29.
