Background technique
The rotating part of slewing, i.e. rotor inevitably generate unbalance mass, in casting, process,
High vibration can be generated when rotor high speed rotation, influences equipment safety, rotor need to be moved to eliminate this adverse effect
Balance, and it is dynamically balanced crucial exactly determining with the circumferential position re-mounted.Counterweight is determined during rotor dynamic balancing at present
Circumferential installation site needs to take off bearing housing measured phase angle, and this method error of measuring is big, heavy workload, consuming time is long.
Summary of the invention
The object of the present invention is to provide a kind of slewing phase angle measurement device, can under the premise of not taking off bearing housing,
Weight installing position is determined by disk turn, can save workload and working hour, and measure accurately.
The present invention provides a kind of slewing phase angle measurement devices, including photoelectric sensor, signal receiving device, meter
Counting apparatus, and the label disk for being mounted on slewing rotor shaft or shaft coupling；
It marks and is equidistantly pasted with 72 reflective tapes at the same Radius of disk, the angle of the every equal part of reflective tape is 5 °, is used
In the axle journal of rotor shaft or shaft coupling is divided into uniform 72 equal part；
Photoelectric sensor is connect with signal receiving device, and signal receiving device is connect with counting device, in disk turn
The period of the day from 11 p.m. to 1 a.m, the signal for issuing photoelectric sensor returns to a signal after being irradiated to reflective tape, and is recorded and returned by counting device
Signal number the angle that rotor turns over is calculated by 5 × signal number.
Further, which further includes the photoelectric sensor power supply unit connecting with photoelectric sensor.
According to the above aspect of the present invention, can be passed through under the premise of not taking off bearing housing by slewing phase angle measurement device
Disk turn determines weight installing position, saves workload and working hour, and measure accurately.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And can be implemented in accordance with the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention and the accompanying drawings.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of slewing phase angle measurement device of the present invention.
Figure label:
1- marks disk；2- reflective tape；3- photoelectric sensor；4- photoelectric sensor power supply unit；5- signal receiving device；
6- counting device.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Join shown in Fig. 1, present embodiments provides a kind of slewing phase angle measurement device, including photoelectric sensor 3, letter
Number reception device 5, counting device 6, and the label disk 1 for being mounted on slewing rotor shaft or shaft coupling；
It marking and is equidistantly pasted with 72 reflective tapes 2 at the same Radius of disk 1, the angle of the every equal part of reflective tape 2 is 5 °,
For the axle journal of rotor shaft or shaft coupling to be divided into uniform 72 equal part；
Photoelectric sensor 3 is connect with signal receiving device 5, and signal receiving device 5 is connect with counting device 6, in disk
The turn period of the day from 11 p.m. to 1 a.m, the signal for issuing photoelectric sensor 3 returns to a signal after being irradiated to reflective tape 2, and is remembered by counting device 6
The angle that rotor turns over is calculated by 5 × signal number in the signal number that playback returns.
The device marks on disk 1 in use, in advance in rotor shaft or to adjustment notch disk 1 on wheel (shaft coupling)
72 reflective tapes 2 are uniformly pasted, then the angle between two reflective tapes is 5 °, after disk turn, when the key of rotor itself passes on from one to another
After sensor receives signal, starting to count present apparatus key phase received signal quantity n, then the angle turned over is 5 ° × n,
Thus the circumferential installation site of dynamic balance weight is accurately determined.
The slewing phase angle measurement device can accurately measure certain circumferential position and key phase 0 in shaft at the low rotational speed
Angle between point；Weight installing position can be determined under the premise of not taking off bearing housing；It is mountable on dynamic and static component, can be anti-
It is multiple to use；Determine weight installing position accurately, conveniently.
In the present embodiment, which further includes the photoelectric sensor power supply unit 4 connecting with photoelectric sensor.
The above is only a preferred embodiment of the present invention, it is not intended to restrict the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is several improvement and
Modification, these improvements and modifications also should be regarded as protection scope of the present invention.
