    • The present disclosure relates to a slewing gear device (110) for rotating a superstructure (102) of a construction machine (100) relative to an undercarriage (104) of the construction machine (100). The slewing gear device (110) may comprise a ring gearwheel (126), at least one inner gearwheel (132), and a plurality of lubricant dispensing units (136) configured to dispense a lubricant onto inner teeth (130) of the ring gearwheel (126). The lubricant dispensing units (136) may be arranged spaced apart from one another about the central axis (A) in a specific manner, which may ensure proper lubrication of the inner teeth (130) of the ring gearwheel (126) also if operations with limited swing angles only are performed by the construction machine (100).

    • A mounting block (114) for a hydraulic mining shovel (100) is disclosed. The mounting block (114) is provided to couple a module (110) to a superstructure (106) of the hydraulic mining shovel (100). The mounting block (114) includes a first surface (202) that engages with the module (110) and a second surface (204) that engages with the superstructure (106) via a weld (400). The mounting block (114) further includes a peripheral surface (206) extending between the first surface (202) and the second surface (204). The peripheral surface (206) includes a first portion (208) having a first tapering cross section (209). The first tapering cross section (209) tapers inwardly towards the first surface (202) in a first direction (210) defined from the second surface (204) to the first surface (202).
    • 公开了一种用于液压挖掘机(100)的安装块(114)。 提供安装块(114)以将模块(110)联接到液压挖掘机(100)的上部结构(106)。 安装块(114)包括与模块(110)接合的第一表面(202)和经由焊接(400)与上部结构(106)接合的第二表面(204)。 安装块(114)还包括在第一表面(202)和第二表面(204)之间延伸的外围表面(206)。 外围表面(206)包括具有第一锥形横截面(209)的第一部分(208)。 第一锥形横截面(209)在从第二表面(204)到第一表面(202)限定的第一方向(210)上朝向第一表面(202)向内渐缩。
