Description
[technical field]
The utility model belongs to motor measurement mechanism technical field, especially relates to a kind of rotary large-scale cross-flow generator rotor survey round belting of regulating the location with ball bearing.
[background technology]
Large-scale cross-flow generator, its rotor does not have axle construction for the dish class, is connected with the hydraulic turbine main shaft flange by the rotor field spider endoporus.Yoke closed assembly and magnetic pole in rotor assembling mount in the operation process, all with the rotor field spider endoporus as location, measuring basis.Surveying round belting is its important measurement mechanism.
It is fixedly pattern of axle that tradition is surveyed the round belting structure, with the rotor field spider endoporus be little clearance fit, survey round belting support also is clearance fit on axle and rotates around axle.Because the gap makes axle become the ray state; Simultaneously the axis of rotor field spider endoporus is a virtual state, causes the axis of axle to be difficult to the parallel axes of rotor field spider and overlaps.So, when each the use, the survey round belting revolves and turns around, and multiple " 0 " state of its dial gauge is all uncertain between 0.3-0.5mm, and the concentricity precision of each axial plane survey circle data is relatively poor, is difficult to reach the rotor circularity of designing requirement and the measuring accuracy of cylindricity.In addition, the rotor inner hole diameter of every kind of model unit differs, and needs spindle specially to cooperate with it, can't implement generally, and axle needs grinding, swing bearing machining precision height, and the frock manufacturing expense is big.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provide a kind of that adopt the ball bearing governor motion and have simple in structure, easy to manufacture, easy to adjust, versatility is wide, the frock expense is low and the large-scale cross-flow generator rotor of the high advantage of measuring accuracy is surveyed round belting.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of large-scale cross-flow generator rotor is surveyed round belting, comprises column, side is housed respectively in the both sides, bottom of column supports, and ball bearing is equipped with in the bottom that described side supports; Guidepost is equipped with in bottom at described column, in the both sides of guidepost ball bearing is housed; One side is equipped with support on the top of described column, in an end of support measuring staff is housed.
By regulating the contact condition of 3 ball bearing of rotor field spider endoporus and hole wall, make it guarantee to survey that round belting is flexible, in the smooth rotation, movement clearance reaches optimum condition.General scalable rotation concentricity is in 0.05mm; Rotate in the endoporus of lower end owing to survey the whole fixed point of round belting, thereby multiple " 0 " degree basically identical of each axial cross section circle dial gauge when measuring, up big and down small phenomenon can not appear.
By regulating the vertical contact condition of 3 ball bearing of support outerplanar, can guarantee to survey round belting when rotated the axial plane degree of each cross section circle about 0.3mm.
Because the bearing arrangement of endoporus location is designed to adjustable state, survey the circle request for utilization so can satisfy the rotor diameter of hole dimension in the certain limit.
The beneficial effects of the utility model are: the measurement size that this device has used is φ 7350mm to the maximum; The radius measurement tolerance is: ± 0.15mm; Cylindricity tolerance is: ± 0.1mm (cooperation is hung vertical steel wire and measured); Measurement of planeness tolerance is: ± 0.15mm; Has advantage simple in structure, easy to manufacture, easy to adjust, that versatility is wide, the frock expense is low and measuring accuracy is high; Satisfy the accuracy requirement of the cross-flow generator large-scale dish-type rotor cylindrical and the measurement of planeness fully, use when being particularly suitable for the power station assembled in situ.
[description of drawings]
Fig. 1 is the structural representation of the utility model when behaviour in service;
Among the figure: 1-guidepost, the support of 2-side, 3-column, 4-support, 5-measuring staff, 6-generator amature, 7-ball bearing, 8-endoporus, 9-rotor field spider.
[embodiment]
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, a kind of large-scale cross-flow generator rotor is surveyed round belting, comprises column 3, side is housed respectively in the both sides, bottom of column 3 supports 2, and ball bearing 7 is equipped with in the bottom of described side support 2; In the bottom of described column 3 guidepost 1 is housed, ball bearing 7 is housed in the both sides of this guidepost 1; A side is equipped with support 4 on the top of described column 3, in an end of this support 4 measuring staff 5 is housed.8 three ball bearing of endoporus 7 by regulating rotor field spider 9 and the contact condition of endoporus 8 walls, make it guarantee to survey round belting flexibly, in the smooth rotation, movement clearance reaches optimum condition.General scalable rotation concentricity is in 0.05mm; Owing to survey the rotation lower end endoporus 8 in of the whole fixed point of round belting, thereby each axial cross section circle spends basically identical in multiple " 0 " of dial gauge when measuring, and up big and down small phenomenon can not occur; By regulating the vertical contact condition of 3 ball bearing 7 of support 4 outerplanars, can guarantee to survey round belting when rotated the axial plane degree of each cross section circle about 0.3mm; Because the bearing arrangement of endoporus location is designed to adjustable state, survey the circle request for utilization so can satisfy the rotor diameter of hole dimension in the certain limit.
Method of operating during enforcement and order are:
Phase one: rotor field spider is in place, transfer centrosome flange face level → just folded magnet yoke blanking sheet 100mm height, at rotor field spider center pit lift heavy plumb line, with the adjustment of milscale gauge rod and measure yoke cylindrical original bench mark → unload plumb line, install to adjust and survey round belting, the dial gauge thimble is aligned yoke cylindrical original bench mark position, pointer be transferred to " 0 " position, survey round belting check dial gauge along the circumference rotation and be returned to " 0 " → continue lamination and monitor adjustment yoke circularity and linearity at any time until finishing whole yoke closed assembly with surveying round belting.
Subordinate phase: split out the survey round belting, once more lift heavy plumb line → first magnetic pole of extension, adjust magnetic pole external diameter and linearity → second time dress with the milscale gauge rod and survey round belting, be benchmark with first magnetic pole, the dial gauge thimble aligns the pole arc peak, the dial plate pointer is transferred to " 0 " position → utilization survey round belting mounts all the other magnetic poles of detection one by one.
