Definitions
- the invention relates to a roller cage for at least one deep rolling roller of a tool for deep rolling punctures or radii at bearing points of crankshafts, the deep rolling roller being loosely guided on a portion of its circumference on the roller cage or within a concave recess in the roller cage.
- reference numeral 22 shows deep rolling rolls which are loosely guided in roller cages, reference numeral 15.
- the roller cages 15 are attached to the outer end of the long leg of an L-shaped tool holder, provided with the reference number 20.
- the deep rolling rollers are described, for example, in US Pat. No. 5,806,184.
- the deep rolling rollers provided with the reference number 40 are guided in roller cages with the reference number 26.
- the size and shape of the deep rolling rollers 40 can be seen from FIGS. 4a to 4c.
- a rolling bearing which are arranged in the body between the cage and the rolling elements made of lubricating material.
- the sheet metal cage of the known roller bearing itself is not in contact with the roller bodies and is therefore not exposed to wear from the rolling elements.
- the known roller bearing is intended for use in machines which process products in which contamination by oils, greases or solid lubricants is to be avoided.
- the textile and food industry are examples of applications for the known roller bearing.
- Deep rolling rollers for deep rolling punctures or radii at crankshaft bearings are highly stressed tools. They wear out, for example, due to material breakouts, similar to gearwheels or rolling elements in rolling bearings.
- the deep rolling roller is supported in the vertical direction upwards by a guide roller.
- the entire load on the deep rolling roller is caused by contacts between the deep rolling roller, the guide roller, the crankshaft and the roller cage.
- the roller cages opposite each deep rolling roller only the roller cage in the drive direction of the crankshaft wears out. To reduce this wear, it is generally known to offset the deep rolling roller by a small amount compared to the line formed by the axis of the crankshaft and the guide roller.
- the deep rolling rollers are not only subjected to pressure, however, slip also occurs between the deep rolling roller, the crankshaft and the guide roller because the rolling effective radii are different.
- the roller cage transmits the generated rolling force directly to the deep rolling roller and is therefore used the slip movement is heavily loaded and accordingly wears out quickly. Up to now, this wear has been counteracted by applying rolling oil to the deep rolling tools or oil-air lubrication.
- Low-viscosity oil (5 CST) is used for oil lubrication and is supplied very abundantly.
- the task for the invention results from this to reduce the wear of the roller cage.
- the funds used should be easy to use, reliable and inexpensive at the same time.
- a suitable material of this type is, for example, graphite.
- a graphite block is arranged within a recess in the roller cage and, during deep-rolling, releases graphite particles to the deep-rolling roller, which bring about their lubrication.
- the wear of the graphite-containing part of the roller cage is controlled in a simple manner in that the remaining parts of the roller cage, which do not contain graphite, are kept so small in their dimensions that a sufficiently large graphite layer can always be removed with their wear ,
- a solid lubricant such as Mo S2.
- a sintered metal material is considered as a roller cage.
- the porosity of the sintered metal material enables a lubricant to be applied under pressure from the outside. The lubricant travels through the sintered metal material and exits at those points where the roller cage is in contact with the deep rolling roller.
- the invention is based on a
- Fig. 1 is a side view of the engaged parts of a deep rolling tool
- Fig. 2 shows a roller cage, in which a lubricant-dispensing element is contained.
- the number 1 in FIG. 1 denotes a circle which represents the circumference of a bearing point of any crankshaft.
- the crankshaft 1 rotates in the direction of the arrow 2.
- a deep-rolling roller 3 engages in a recess (not shown) in the crankshaft 1.
- the deep-rolling roller 3 is supported in the vertical direction from above by a support roller 4, which in turn rotates in the direction of the arrow 5.
- the deep rolling roller 3 itself is loosely guided by a roller cage 6 which touches the deep rolling roller 3 in the direction of arrow 7.
- the contact between the deep rolling roller 3 and the roller cage 6 is shown enlarged in FIG. 2.
- the roller cage 6 has a recess 11.
- a graphite block 8 is embedded, which represents the direct contact between the roller cage 6 and the deep-rolling roller 3.
- the ratio of the contact surface 9 between the end face of the graphite block 8 and the deep-rolling roller 3 and the surfaces 10 of the wall of the roller cage 6 which laterally supports the graphite block 8 is selected such that a sufficient amount of graphite can always be released from the graphite block 8 to the deep-rolling roller 3 when the roller cage 6 wears.
- the ratio of the areas to be considered is determined experimentally.
