Definitions
- the invention relates to a deep rolling head of a Deep rolling tool for deep rolling of radii or Engraving on the main and stroke journal of Crankshafts with a housing in which one or two Deep-rolling rollers at a lateral distance from each other, corresponding to the axial width of the respective Bearing, with little play in two Roller cages are loosely rotatable and the Roller cages on the crankshaft facing Front side of the housing are fastened with holders, which the roll cages each on their the Support fixed rollers facing away from end faces and at the same time lead laterally.
- the well-known deep rolling head is common that the roller cages on the housing of the deep rolling roller head each secured with L-shaped holders. With help The holder can roll cages in a predetermined Position brought and fixed on the deep rolling head become. It is envisaged that the deep rolling in loose the respective roller cages with little play be guided rotatably. This game is usually about 0.2 mm. In addition, it is envisaged that the Deep rolling against the center of the housing of the A deep rolling roller head around which a leading role for the deep rolling rolls on which the Support fixed rollers against the crankshaft, a Offset of about 0.2 mm. In addition, the Fixed rollers in the deep rolling head also one more Spread in the axial direction.
- the exact, i. specified position of the deep rolling rollers in Deep rolling head is crucial for its service life.
- wear which is the Play between the deep rolling rollers and the roller cages in the course of using the deep rolling tool increased. From this it becomes evident that the exact Adjusting the deep rolling rollers in the deep rolling head a particular importance.
- the setting is made at known from the prior art Deep rolling roller heads over the L-shaped bracket for the Roller cages. In the best case, there is for this Setting adjustment gauges. But it is also usual that Manual adjustment by a trained specialist allow. However, it was possible to observe that the life of the deep rolling rolls and the Roll cages essential of the skill of the adjusting expert is influenced. It is also Setting the fixed rollers a lengthy Activity which requires a lot of working time.
- the task is characterized by a novel embodiment of the Housing of the deep rolling roller head solved according to the features of the main claim.
- the organ consists of a simple, flat flap, one end of which is on the projection of the Housing is bolted and the other, free end cantilevered into the groove on the bottom of the Roller cage engages.
- it can also be a single one Lug be provided which bridges both roller cages and with its two ends on the respective projection of Housing of the deep rolling roller head is releasably screwed.
- the deep rolling roller head 1 has an approximately rectangular, flat housing 2.
- the lower end face 3 of the housing. 2 is facing the crankshaft 21, of which Fig. 1 the Section through any main bearing shows whose Bearing journals each side of radii or punctures 22 be limited.
- these radii or punctures 22 engage fixed rollers 4, which in turn with little play between two adjacent roller cages 5 and 6 are rotatably mounted.
- new condition of the Deep rolling tool is the game between the Deep rolling roller 4 and the two roller cages 5 and 6 each about 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 each other and also a lateral Distance to the center of rotation 7 of the housing. 2
- FIG. 2 shows the two recesses 9 on the front side 8 of a roller cage 5.
- the in the Figure 2 recognizable inclined position of the two recesses. 9 at the same time corresponds to the inclined position of the deep rolling rollers. 4 in the deep rolling head 1.
- roller cages 5 and 6 are supported corresponding projections 11 and 12 from.
- the projections 11 and 12 each jump on the bottom 3 of Housing 2 and give between each other Recess 13 free, wherein the two roller cages 5 and 6 and the deep rolling rollers 4 are received.
- the Roller cages 5 and 6 are connected to the housing 2 or with its projections 11 and 12 not connected. They are in the recess 13 between the both projections 11 and 12 loosely mounted and guided. In this case, the roller cages 5 and 6 are based with their rear end faces 10 each on corresponding Surface 14 of the projections 11 and 12 from.
- each tabs 15 are provided.
- the tabs 15 exist made of flat irons of small length and width, and are in each case via screws 16 with the respective projection 11 or 12 of the housing 2 releasably connected.
- the front, freely projecting end of the two tabs 15 attacks each in a groove 18, which on the bottom 19 of the Roller cage 5 and 6 is provided (Fig. 2).
- two tabs 15 may also be a single tab be provided, which via the two roller cages. 5 and 6 engages and the distance between the end faces. 8 bridged.
- a spacer 20 inserted, the even only a small thickness between 0.1 mm and 0.5 mm, preferably 0.2 mm.
- About the spacer 20 can the game between the deep rolling 4 and the Both roller cages 5 and 6 are compensated.
- the spacer 20 but also serves to the Center of rotation of the deep rolling roller 4 with respect to 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, adjust.
- tab 15 may also be a pin provided be, which is the holder and guide of each Roller cage 5 and 6 on the projection 11 and 12 of the housing 2 secures.
- the spacer 23 of Fig. 3 is a prismatic body of opposite to the thickness of the Spacer 20 of FIG. 1 substantially larger axial Length. 3 shows only a single spacer 23, which the adjacent roll cage 5 on his rear end face 10 is supported. Analogous to this also the roller cage 6 a similar spacer be assigned according to the spacer 23.
- the spacer 23 is on two cylindrical pins 24 out in the mutual distance 25 from each other in holes 26th engage within the projection 11 of the housing 2.
- the pins 24 are parts of the spacer 23 and with this firmly and inextricably linked.
- the distance 25 makes room for the engagement of the screw 16 for the Tab 15 in the projection 11th
