Abstract

The invention discloses a process bearing block for a flapping test of a steam turbine rotor shaft, which comprises a base plate, two side frame plates of which the bottom ends are fixed on the base plate, and a base of a front baffle plate and a rear baffle plate which is positioned in the middle and of which the two ends are fixed on the two side frame plates respectively. The process bearing block further comprises an adjusting mechanism flapping up and down, an adjusting mechanism flapping horizontally, a flexibility self-adjusting mechanism and a bearing bush, wherein the adjusting mechanism flapping up and down comprises two hydraulic jacks and two locking nuts; the adjusting mechanism flapping horizontally comprises a sliding seat and a spherical seat; the flexibility self-adjusting mechanism is a spherical bearing; and the bearing bush is placed on the spherical bearing. Through the technical scheme of the process bearing block for the flapping test of the steam turbine rotor shaft, the process bearing block has the advantages of compact structure, high bearing capacity, portable operation, good bearing bush interchangeability, easy manufacture, economization and practicability.

Description

technical field [0001] The invention relates to a technical bearing block used for shaft drift test of steam turbine rotor. Background technique [0002] According to the design requirements, when the 1000MW and combined cycle steam turbine units are assembled, the shaft float test needs to be carried out before the rotor falls into the cylinder to check its radial dynamic and static clearance. The specific steps are as follows, use the dummy shaft to find the center - adjust the bearing seat - measure the digital display and adjust the holding rings and partitions - replace the bearing bush - the rotor falls into the cylinder - use the deflection rotor up and down, left and right - measure the dynamic and static clearance - crank. [0003] Since the product bearing seat does not participate in the assembly, a process bearing seat with the function of up, down, left, and right adjustment and high-precision interchangeable bearing pads is required. The technical bearing sea...
