Definitions
- the invention relates to the fixing of a bearing pin in a receiving bore of a housing which can be caulked at least at one end to the bore to achieve a positive and / or positive connection, the bolt having a lateral surface with a hardness that is greater than the hardness of its end faces is.
- Such a bolt for mounting the roller of a rocker arm acted upon by a cam is previously known from US Pat. No. 5,054,440.
- This rocker arm has a fork-shaped section, the two cheeks of which each have a receiving bore through which the bearing pin is guided. It carries a roller supported by needles, which is acted upon by a cam.
- the bolt is held in the receiving bore by caulking, that is to say it is acted upon on one or both end faces with a corresponding tool, so that part of its material is displaced in the radial direction into the receiving bore.
- the object of the invention is therefore to develop a bearing pin which has a long service life even under high load conditions.
- this object is achieved according to the characterizing part of claim 1 in conjunction with its preamble in that the entire bolt is carbonitrided, quenched and tempered, so that a hardness of HV 745-950 (HRC 62-68) is realized, then the thus treated bolts for setting a hardness of HV 212-305 (HRB 93-HRC 30) are soft-annealed before the outer surface is subjected to induction hardening to set a final hardness of HV 745-950 (HRC 62-68).
- the advantage of such a bolt produced in the manner according to the invention is that there is an increased hardness and a higher residual compressive stress in the raceway area, so that the bolt has increased wear and fatigue strength in this area, with soft end faces at the same time.
- Carbonitriding is known to the person skilled in the art as a thermochemical method for treating a workpiece in the austenitic state with the purpose of enriching the surface layer with carbon and nitrogen, both elements subsequently being in solid solution in the austenite. This treatment is immediately followed by quenching with the goal of achieving hardening.
- carbonitriding realizes a specific layer structure in the form of a connecting layer and a diffusion layer underneath. While the connection layer is decisive for all the workpiece properties that are related to the effects on the immediate surface, i.e. the wear behavior and the corrosion resistance, the mechanical properties of the workpieces, the fatigue strength and the tensile strength relate to the diffusion layer.
- tempering takes place.
- internal stresses are relieved, so that hardness and strength decrease, while toughness and ductility increase.
- soft annealing of the carbonitrided, quenched and tempered stud to set the hardness values HV 212-305 (HRB 93-HRC 30), which are the hardness values for the two ends of the stud.
- This soft annealing is used in particular to improve the deformability of the bolt, so that it can be easily plastically deformed in its end regions and thus can be caulked to a receiving bore in a simple manner.
- the annealing temperatures depend on the material used and are between 650 and 700 ° C for steel.
- the purpose of soft annealing is to give the steel a structure that is suitable for hardening and to convert it to a soft, easily machinable state.
- Induction hardening is currently the most widespread thermal surface hardening process.
- a magnetic alternating generated field that induces an alternating current in an electrically conductive workpiece (bolt) according to the transformer principle.
- the direct conversion of the electrical energy into thermal energy via internal heat sources thus leads to the heating of the component, the energy transfer taking place without contact.
- the heating is mainly limited to the boundary layer in which the internal heat sources are effective.
- heat conduction leads to radially progressive heating of the component. It follows that the hardening depth can be adjusted with simple means and can always be adapted to the respective application without great effort.
- the bolt should be solid or at least hollow in the section of its front ends.
- the advantage of a hollow cylindrical bolt is that in addition to reducing the weight, the widening when caulking on its end faces is favored.
- FIG. 1 shows a schematic side view of a valve train of an internal combustion engine
- Figure 3 is an enlarged view of a bolt according to the invention.
- the rocker arm 1 of a valve train of an internal combustion engine shown in FIG. 1 is pivotally mounted about its axis 2. At its right-hand end region, the rocker arm 1 is operatively connected to the shaft of the gas exchange valve 3, which is held in the closed position by the associated spring 4. At its left-hand end, the roller 5, which is in contact with the cam 7, is held in the rocker arm 1 via the pin 6. During its rotation, a pivoting movement of the rocker arm 1 about its axis 2 is triggered such that its left-hand part is moved up and its right-hand part is moved down, the gas exchange valve 3 opening.
- the rocker arm 1 has a fork-shaped part with the cheeks 1.1, 1.2 spaced apart from one another at its left-hand end.
- the aligned bore 1.3 extends through these cheeks 1.1, 1.2, in which the bolt 6 is arranged, which carries the roller 5 mounted on the roller ring 8.
- the bolt 6 forms the inner raceway 6.1 for the rolling element ring 8 and is caulked on its two end faces 6.2 in the receiving bore 1.3 of the cheeks 1.1, 1.2 of the rocker arm 1.
- the bearing pin 6 on the one hand must be soft on its end faces 6.2 in order to be able to be calked at all and on the other hand must have sufficient hardness in the raceway area 6.1 in order to be able to function as a resilient radial bearing.
- the purpose of the soft annealing is on the one hand to give the steel a structure suitable for hardening and on the other hand to convert it to a soft, easily machinable state.
- the stud has a hardness of HV 250, this hardness being the final hardness for its two end faces 6.2 at the same time.
- This is finally followed by partial induction hardening of the lateral surface of the bolt 6 in a known manner, so that it has a final hardness of HV 800.
- the pin 6 has the area 6.3, which serves as a raceway 6.1 for the rolling elements 8.
- This area 6.3 contains the structure described in claim 2 after induction hardening, that is to say finely divided spherical carbides in a matrix of tempered martensite with a residual austenite content of 5-25%.
- the transition area 6.4 of the bolt 6 separates the hardened area 6.3 from the soft end faces 6.2.
