Abstract
The utility model relates to an improve axle centering and measure composite set of precision, including being used for the fixed axle to avoid the not hard up central addendum cone of axle and prevent a drunkenness clamp plate, wherein central addendum cone has cup jointed nut and steel sheet including fixing the addendum cone in screw rod body one end on the screw rod body, and wherein two nuts has been cup jointed respectively at both ends around the steel sheet, prevent a drunkenness clamp plate and then fix the neck at the screw rod body have to lie in the screw rod the body radial slide bearing and the steel sheet at both ends from top to bottom, wherein the radial slide bearing outside is provided with rather than the fixed bearing frame that links to each other, then is provided with on the steel sheet and adjusts jackscrew and housing pin. The effect is obvious on improve unit axis centering precision, quality and work efficiency, having shortened time of axis centering, has great extended application scope, like turbo generator set, large -scale air -blower, large -scale dust exhausting fan, air exhauster etc.
Description
Technical field
This utility model belongs to large high-speed slewing service technique field, relates to oneImprove the combination unit of alignment measurement precision。
Background technology
Electromotor that current large-scale vapour (gas, electricity) drives, gas compressor, aerator, air exhauster etc. remain metallurgy industry and use one of relatively broad capital equipment, and large high-speed rotation special equipment maintenance is front and alignment measurement adjustment after maintenance, one extremely important and indispensable operation in the repair and maintenance work that the equipment that is to ensure that is properly functioning.
Being the main method of overhaul of the equipments by junction box levelling axis centering between slewing, shaft assignment data demand is strict, it is necessary to accomplish accurate.Currently used measuring appliance is many based on dial gauge with laser alignment instrument.
The subject matter present situation that shaft assignment process exists has:
1, using bush(ing) bearing is supporting mass, by plane thrust slide bearing bear axial load and limit the steam turbine of axially-movable, turbocompressor, turbo-expander, etc. the rotor of unit, axial gap has 0.35 to 0.7mm respectively.Rotor as easy as rolling off a log generation during the jiggering of shaft assignment is bigger and nondirectional axial float, causes end face (opening) error of measured data (angular deviation).
2, using sliding bearing as the high-rating generator of radial support rotary motion and motor rotor, rotor journal width ratio plain journal bearing width wants width in design, and axial gap has 5～30 respectively.So unit rotor as easy as rolling off a log generation during the jiggering of shaft assignment is bigger and nondirectional axial float, cause end face (opening) error of measured data (angular deviation).
3, the rotor weight of Diagnosing System for Oil Pump is at 3000 more than 20000kg mostly, owing to rotor produces nondirectional axial float during the jiggering of shaft assignment, the error of measured data caused directly affects centering adjustment work, and need to increase the substantial amounts of time, human and material resources go repeatedly to revise, measure, adjust, and directly affects the raising of work efficiency.
Utility model content
In order to overcome the disadvantages mentioned above of prior art, this utility model provides oneImproving the combination unit of alignment measurement precision, it hasSimple in construction, assemble, adjust, easy to operate feature, the axis Alignment measuring process in the large high-speed slewing maintenance with sliding bearing as supporting mass can be applied to, axial float be can the most effectively limit, alignment measurement precision and work efficiency improved.
This utility model solves the technical scheme is that one of its technical problemImprove alignment measurement precision combination unit, including for fix axle avoid axle loosen center addendum cone andAnti-axle play pressing plate, wherein center addendum cone includes the addendum cone being fixed on screw body one end, screw body is socketed with nut and steel plate, two nuts wherein it are respectively sleeved in steel plate rear and front end, described anti-axle play pressing plate is then fixed on the cervical region of screw body, include bush(ing) bearing and the steel plate being positioned at the upper and lower two ends of screw body, wherein outside bush(ing) bearing, be provided with the bearing block being secured to be connected, steel plate is then provided with adjustment jackscrew and housing pin.
Described addendum cone is fixed in screw body by rolling bearing.
The beneficial effects of the utility model are: can rationally limit axial float during detecting the large high-speed slewing shaft assignment with sliding bearing as supporting mass, improve alignment measurement precision, there is simple in construction simultaneously, assembling, adjust, convenient and reliable operation, it is effectively shortened the detection time during large high-speed slewing shaft assignment, improve the features such as work efficiency, by the application in the maintenance process of large high-speed slewing, we can see that this utility model is improving unit axis accuracy of alignment, quality and work efficiency, the time upper effect shortening axis centering is obvious, there is bigger expanded application scope, such as Turbo-generator Set, large blower, large-scale dedusting fan, air exhauster etc..
