図8は、従来技術に係る旋回軸受の縦断面図であり、油圧ショベルへの搭載例 である。図9は、図8の旋回軸受部分を拡大した拡大図である。 FIG. 8 is a vertical cross-sectional view of a slewing bearing according to a conventional technique, which is an example of mounting on a hydraulic excavator. FIG. 9 is an enlarged view in which the slewing bearing portion of FIG. 8 is enlarged.
【0003】 図8及び図9に示すように、旋回軸受23は、内輪23a,外輪23b,及び 鋼球24を有する。内輪23aは、リング状の部材であって、下部送行体21の 上端部にボルト等で締結されている。内輪23aの外周面の周方向には、縦断面 がU字状である鋼球24の転動面23dを有し、また内輪23aの内周面の周方 向には、内歯23cが一体に形成されている。外輪23bは、リング状の部材で あって、上部旋回体22の下端部にボルト等で締結されている。外輪23bの内 周面の周方向には、縦断面がU字状である鋼球24の転動面23eを有する。内 輪23aは、転動面23dと転動面23eとの間に鋼球24を介装することによ って外輪23bに旋回可能に嵌装されている。鋼球24は、外輪23bが内輪2 3aの外周を旋回するのに伴い転動面23d,23eを転動する。また、内輪2 3aの外周面の下方部及び外輪23bの内周面の上方部より突出したシール27 によって内輪23aと外輪23bとのすき間がシールされる。As shown in FIGS. 8 and 9, the slewing bearing 23 has an inner ring 23 a, an outer ring 23 b, and a steel ball 24. The inner ring 23a is a ring-shaped member, and is fastened to the upper end portion of the lower transporting body 21 with bolts or the like. In the circumferential direction of the outer peripheral surface of the inner ring 23a, a rolling surface 23d of a steel ball 24 having a U-shaped longitudinal section is provided, and in the circumferential direction of the inner peripheral surface of the inner ring 23a, internal teeth 23c are integrally formed. Is formed in. The outer ring 23b is a ring-shaped member and is fastened to the lower end of the upper revolving structure 22 with bolts or the like. The rolling surface 23e of the steel ball 24 having a U-shaped vertical section is provided in the circumferential direction of the inner peripheral surface of the outer ring 23b. The inner ring 23a is rotatably fitted to the outer ring 23b by interposing a steel ball 24 between the rolling surface 23d and the rolling surface 23e. The steel ball 24 rolls on the rolling surfaces 23d and 23e as the outer ring 23b turns around the outer circumference of the inner ring 23a. The gap between the inner ring 23a and the outer ring 23b is sealed by the seal 27 protruding from the lower part of the outer peripheral surface of the inner ring 23a and the upper part of the inner peripheral surface of the outer ring 23b.
【0004】 上述の如き構成の旋回軸受は、内輪23aの内歯23cと歯合する出力軸歯車 26が、上部旋回体22に固定された旋回減速機25によって回転駆動されるこ とにより、上部旋回体22を鉛直軸まわりに旋回せしめる。In the slewing bearing having the above-described configuration, the output shaft gear 26 that meshes with the inner teeth 23c of the inner ring 23a is rotatably driven by the slewing reducer 25 fixed to the upper slewing body 22. The revolving unit 22 is revolved around the vertical axis.
【0005】[0005]
上述の如き従来技術に係る旋回軸受は、内輪23aの内周面及び外周面に内歯 23c及び転動面23dが一体に成形されている。 In the conventional slewing bearing as described above, the inner teeth 23c and the rolling surface 23d are integrally formed on the inner and outer peripheral surfaces of the inner ring 23a.

At that time, the rolling surface 23e of the replaced inner ring 23a and the inner ring 23a are continuously used. The steel ball 24 and the outer ring 23b may not fit well with the rolling surface 23d, and the swivel function of the swivel bearing may deteriorate. Further, when the rolling surface 23d or the rolling surface 23e is damaged and only the inner ring 23a or the outer ring 23b is replaced, there is a possibility that the turning function is deteriorated similarly to the above.
【0007】 そこで、旋回軸受23全体を新品と交換するとなれば、著しいコスト高となる 。Therefore, if the entire slewing bearing 23 is replaced with a new one, the cost will be significantly high.
