Abstract: Disclosed, is a drive (101) for a sedimentation tank (1000) comprising a main ring gear (160) operatively connected to a cage (150) via a web portion (152). A bearing transfer ring (170) is provided to the web portion (152) such that a gap (172) is provided between the bearing transfer ring (170) and the main ring gear (160). The bearing transfer ring (170) is connected to a first bearing race (144) which communicates with a second bearing race (142) that is fastened to a base portion (136) of the drive (101). Torque (T) is delivered to the cage (150) to turn a rake assembly (1002). The gap (172) provides clearance for deflections, distortions, or deformations of the main ring gear (160) caused by bending stresses (B) in the main ring gear (160) may. The bearing transfer ring (170) absorbs stresses imparted to the main ring gear (160) and prevents fasteners (188) connected to stiff bearing races (144) from shearing. Also disclosed is a retrofit kit for a sedimentation tank drive, a sedimentation tank (1000) having a drive (101) according to the above description, and a method of thickening/clarifying slurry (1008) utilizing a drive (101) according to the above description.

Abstract translation: 公开了一种用于沉淀池（1000）的驱动器（101），其包括通过腹板部分（152）可操作地连接到保持架（150）的主环形齿轮（160）。 轴承传送环（170）设置到腹板部分（152），使得在轴承传递环（170）和主齿圈（160）之间设置间隙（172）。 轴承传送环（170）连接到与紧固到驱动器（101）的基部（136）的第二轴承座（142）连通的第一轴承座（144）。 转矩（T）被传递到保持架（150）以转动耙组件（1002）。 间隙（172）提供由主环形齿轮（160）中的弯曲应力（B）引起的主环形齿轮（160）的偏转，变形或变形的间隙。 轴承传送环（170）吸收施加到主齿圈（160）的应力，并且防止与刚性轴承座（144）连接的紧固件（188）不被剪切。 还公开了一种用于沉淀池驱动装置的改装套件，具有根据上述说明的驱动装置（101）的沉淀池（1000），以及利用根据本发明的驱动装置（101）来增稠/澄清浆料（1008）的方法 以上说明。
