- Laminate and fix the thin plates 3 together For example, as shown in FIGS. 3 and 4, the rack teeth 2 are arranged in the axial direction (the direction indicated by the arrow 5 is the axial direction) so that the streaks of the rack teeth 2 of the laminated thin plates 3 form a splint. .) Are shifted from each other by a predetermined amount and stacked and fixed to each other. In FIG. 4, the tooth tips of the rack teeth 2 are filled so that the deviation of the rack teeth 2 between the thin plates 3 can be easily understood.
- the fixing method in the thin plate laminating step can be adopted as the fixing method in the thin plate laminating step.
- an adhesive is applied in advance to the mating surfaces of the thin plates 3, and after the thin plate laminating step, the laminated thin plates 3 are brought into close contact with each other at a predetermined pressure, so that no relative displacement occurs between the thin plates 3. Can be fixed.
- a through hole penetrating the laminated thin plate 3 in the thickness direction is processed, a bolt is inserted into the through hole, and the laminated thin plate 3 is fastened together with the nut. In this way, the thin plates 3 can be fixed so that no relative displacement occurs.
- a cover body 6 made of fibers 4 impregnated with rubber or resin is bonded to the rack teeth 2 of the laminated thin plates 3, and the rack teeth 2 are covered with the cover body 6.
- the cover body 6 for example, as shown in FIG. 5, the front surface 6 a is molded into a rack tooth shape of a general mountain rack, and the back surface 6 b is formed with rack teeth 2 of a plurality of laminated thin plates 3. What is formed into a concavo-convex shape corresponding to the concavo-convex shape to be formed (the concavo-convex shape is not shown) is used.
- FIGS. 3 and 4 immediately after the thin plate laminating step is performed, a step is generated between the tooth surfaces 2 a of the rack teeth 2 that are axially displaced from each other. By covering 2, such a step is eliminated in appearance.
- the rack 1 as shown in FIG. 1 is completed through the above steps.
- the fiber 4 impregnated with the rubber or resin will be described in more detail.
- the fiber 4 impregnated with the rubber or resin can be formed of aramid fiber, nylon, urethane, cotton, silk, hemp, acetate, rayon, fiber containing fluorine, polyester, etc., and impregnated with rubber or resin.
- the fiber shape may be, for example, a short fiber shape or a long fiber shape.
- the rubber material or the resin material enters between the fibers, and the fibers are bonded together to function as the cover body 6. Further, by impregnating the fibers with rubber or the like, wear due to rubbing between the fibers is reduced, and further, it is possible to improve the wearability of the cover body 6 generated between the fibers and the pinion gear. .
