SPIDER BEARING SUPPORT FOR A METER ROTOR

摘要

SPIDER BEARING SUPPORT FOR A METER ROTOR A rotary meter of the vane type having a rotary gate separating the inlet from thc outlet. The rotor vanes and the gate are rotated in a predetermined timed sequence by a suitable transmission such as timing gears which interconnect the rotor and the gate. The rotor is journaled in the housing by axially spaced bearings, at least one of which is mounted in the improved spider bearing support disposed on the outboard side of the rotor. The spider bearing is connected to the housing by detachable holding tabs and positioned concentric to the rotor axis. The housing is enclosed by an end bonnet with the spider bearing support connected to the housing axially below the bonnet and intermediate the bonnet and the rotor. The spider bearing support improves the accuracy of centering the rotor within the housing, decreasing the cost, and improving the access while simplifying the assembly.
