Description
- This application is a continuation of U.S. application Ser. No. 09/381,722, filed Dec. 27, 1999, now allowed, which is a 371 National Phase of PCT/EP97/06170, filed Nov. 6, 1997.
- The present invention is directed to a pressure roller for textile machines, as are used, for example, for a texturing machine for pressing a filament against a delivery roller.
- From German Patent DE-A 29 23 871, a pressure roller is known, the covering of which is formed from plastic or rubber and is arranged, for example, on a support sheath which at the same time forms the outer bearing race of a deep groove ball bearing, by which the pressure roller can be turned on a carrying axle. The outer races of the deep groove ball bearings used require a costly processing; the ball grooves are worked into the outer bearing races and moreover, on the axial ends of the outer bearing races, cylindrical shoulders are provided on the inside, which are provided to receive a grinding arbor. In order to grind the coating of the pressure roller in a flawless manner and with a high degree of precision in running, the pressure roller is clamped onto the grinding arbor.
- Embodiments are also known, in which between the support sheath already mentioned above and the covering, an intermediate sheath is provided, made of aluminum, for example. In this case, the covering and the intermediate sheath form a prefabricated component that is pressed onto the outer bearing race of the deep groove ball bearing, for example. It is advantageous in this pressure roller that a prefabricated unit can be made which on the one hand, is formed from the intermediate sheath provided with the coating and on the other hand, is made from the complete deep groove ball bearing, the outer bearing race of which is constructed simultaneously as a support sheath. The covering must no longer be applied in a costly process, for example, by spraying onto the outer bearing race, but instead the prefabricated units are merely pressed together.
- In both of the embodiment examples described, however, the expensive processing of the outer bearing race of the deep groove ball bearing is disadvantageous. In both cases, the ball grooves and the cylindrical shoulders arranged to the side must be provided for receiving the grinding arbor. Pressure rollers for textile machines are mass-production articles, in the manufacturing of which cost-effective solutions are desired.
- It is thus the purpose of the invention to further develop a pressure roller for textile machines, and in particular for a texturing machine, in such a way that the manufacturing of the deep groove ball bearing is simplified and thus the manufacturing costs for the pressure roller are clearly reduced.
- According to the invention, this purpose is achieved in that a standardized deep-groove ball bearing that has a bearing race and balls that roll on the bearing race is provided, the outer bearing race of which carries the support sheath, where the structural height of the standardized deep groove ball bearing is at most 80 percent of the axial extension of the support sheath. In the pressure roller according to the invention, for example, a simple smooth cylindrical support sheath made of steel can be used, which is provided with the covering on the outside. The standardized deep groove ball bearing can be introduced in a simple way into the support sheath and attached to it for example, by interference fit or adhesive. The standardized deep groove ball bearings are considerably more cost-effective than the known, expensive to produce deep-groove ball bearings having specially constructed outer bearing races. By the specification of the maximum structural height of the standardized deep-groove ball bearing in terms of the axial extension of the support sheath it is ensured that on both sides of the deep groove ball bearing, sufficient space is provided on the support sheath for grinding arbors. In a pressure roller according to the invention that is fitted to the requirements of applied practice, the structural height of the standardized standard deep groove ball bearing amounts to approximately 30% of the axial extension of the support sheath.
- In the pressure roller according to the invention it is possible that the support sheath and the standardized deep groove ball bearing are pulled into the intermediate sheath formed out of aluminum, for example, that carries the covering. It is also conceivable, however, that the support sheath is provided directly with the coating and then pulled onto the outer bearing race of the standardized deep groove ball bearing.
- The support sheath is preferably provided with an inwardly projecting central section for receiving the outer bearing race. When the standardized deep groove ball bearing is arranged in the area of the central section, material displacements, preferably embossings, can be provided on one or even on both sides of the central section, in order to affix the standardized deep groove ball bearing relative to the support sheath. Due to the way in which the central section projects radially inwardly, an introduction and application of suitable tools for the material displacement is possible without problem.
- A pressure roller that is especially light in weight has a support sheath, in which the side sections adjacent to the central section have a wall thickness that is larger than 2.0% and smaller than 6.0% of the outer diameter of the support sheath.
- For application in texturing machines, the pressure roller according to the invention is arranged so that it can pivot transversely to the support axle via a pendulum device. The pendulum device has a pendulum sheath arranged concentrically to the support axle and a pin, which is guided through transverse drill holes of the support axle and the pendulum sheath. The pendulum sheath can, for example, be manufactured out of plastic by injection molding, where it is conceivable to mold the pendulum sheath onto the inner bearing race of the standardized deep groove ball bearing.
- Shown is:
- FIG. 1 is a lengthwise section through a pressure roller according to the invention;
- FIG. 2 is a cross-section through the pressure roller according to the invention according to FIG. 1; and
- FIG. 3 is a detail of a portion of the pressure roller according to FIG. 1 at the area designated “X” which has been enlarged.
- FIG. 1 shows in longitudinal section a pressure roller according to the invention for textile machines, in particular, for a texturing machine for pressing a filament, not shown, against a delivery roller, also not shown. The pressure roller is set in bearings so that it can rotate over a standardized deep groove ball bearing1 relative to a
support axle 2. Acoating 3 formed from rubber or plastic surrounds anintermediate sheath 4 formed from aluminum, which is carried by asupport ring 5. Thesupport ring 5 is pulled onto theouter bearing race 6 of the standardized deep groove ball bearing 1. The structural height (i.e., the axial dimension) of the standardized deep groove ball bearing 1 is set at a maximum of 80% of an axial length or extension of the support ring orsheath 5. In the preferred embodiment, the structural height of the standardized deep groove ball bearing 1 is approximately 30% of the axial extension of thesupport sheath 5. The standardized deep groove ball bearing is arranged so that it can tilt via apendulum device 8 relative to the carryingaxle 2 transversely to the longitudinal axle. Between the two bearingraces balls 9 are arranged, which roll on theball grooves 10, 11 of the bearingraces support sheath 5 preferably made out of steel has acentral section 12 projecting to the inside for receiving theouter bearing race 6, whereembossings 13 provided on both sides of thecentral section 12 engage behind the outer bearing race on the side face. - Side sections14 adjacent to the central section are designed to be thin-walled and are provided with
cylindrical shoulders 15 on the inside for receiving grinding arbors, not shown. The side sections 14 have wall thicknesses that are larger than 2.0 percent and smaller than 6.0 percent of the outer diameter of thesupport sheath 5. - The
pendulum device 8 has apendulum sheath 16 constructed out of plastic, which is arranged concentrically to thesupport axle 2, and which is attached to the inner bearingrace 7. Thependulum device 8 is clearly shown in FIG. 2. The carryingaxle 2 and thependulum sheath 16 are provided withtransverse holes pin 19 is inserted. Since play is provided crosswise to thepins 19 on both sides between the carryingaxle 2 and thependulum sheath 16, it is ensured that the pressure roller can swing around the longitudinal axis of thepin 19. - FIG. 3 shows the
embossings 13 mentioned above which are constructed on several positions of thesupport sheath 5, arranged distributed over the circumference. -
