Motor when operation, the fluted disc moves with motor shaft together, and photoelectric sensor gathers the quantity of the outside tooth of fluted disc and then obtains the rotational speed of fluted disc and export the control unit to and/or display element, and the rotational speed of fluted disc is exactly the rotational speed of motor, and photoelectric sensor can regard the component parts of motor itself as like this, does not need in addition the rotation axis that tests the speed at motor externally mounted, and compact structure is not fragile.
Description
Technical field
This utility model is related to machine field, more particularly, to a kind of motor speed measuring device.
Background technology
During motor uses, in order to improve electric machine speed regulation effect and precision, it usually needs install in motor body and test the speed
Device, reaches the effect of closed loop control by speed feedback signal.The speed measuring device that motor is installed at present usually tests rotation
On axle, the gear of hot jacket is engaged by gear with the gear of hot jacket on electric machine rotational axis, thus transmitting the rotating speed of motor exactly
To the rotary shaft that tests the speed, in rotary shaft, encoder is installed testing the speed, and then records the rotary rpm of motor.
These equipment are all to be installed by shaft coupling and elastic support, and elastic support can buffer installation to a certain extent
The vibration that decentraction causes, on micro-machine, using effect is fine.But large and middle size motor shaft diameter is big, install encoder and
The rotary shaft that tests the speed, it is difficult to ensure that concentricity, often occurs the problem that encoder, the rotary shaft that tests the speed are damaged；The volume of pot motor
Even if only small decentraction when installing of code device, the rotary shaft that tests the speed, the problem of damage similarly occurs in running；
Secondly the rotary shaft that commonly tests the speed adopts shaft coupling to install, and it occupies axial space greatly, for motor for double-ended drive, is then fitted without position
Put, meanwhile, the equipment such as the rotary shaft that tests the speed, encoder installs complexity, and on-site maintenance and replacing are difficult, and equipment requires to use environment
Height, is not suitable for severe working condition.
Utility model content
This utility model provide one kind be directly installed on motor and compact conformation, install simple, be hardly damaged, scene
Motor speed measuring device easy to maintenance.
To achieve these goals, the technical scheme of this utility model offer is：A kind of motor speed measuring device, including motor
Rotating shaft and the bearing being fixed on machine shaft on support, fluted disc is set on the shaft part of machine shaft tail end, in motor housing
At upper position corresponding with fluted disc, installation set is set, in installation set, is provided with photoelectric sensor, photoelectric sensor gathers turning of fluted disc
Speed simultaneously exports to control unit and/or display unit.
During motor operation, fluted disc moves together with machine shaft, the number of the fluted disc external teeth that photoelectric sensor collection is passed through
Measure and then obtain the rotating speed of fluted disc and export to control unit and/or display unit, the rotating speed of fluted disc is exactly the rotating speed of motor, this
Sample photoelectric sensor can be regarded as the ingredient of motor itself it is not necessary in addition install the rotary shaft that tests the speed, knot in outside motor
Structure is compact, is hardly damaged.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
In conjunction with Fig. 1, Fig. 2, a kind of motor speed measuring device, it is fixed on support including machine shaft 10 with by machine shaft 10
Bearing 20, fluted disc 30 is set on the shaft part of machine shaft 10 tail end, at position corresponding with fluted disc 30 on motor housing
Setting installation set 40, is provided with photoelectric sensor 50 in installation set 40, photoelectric sensor 50 gather the rotating speed of fluted disc 30 and export to
Control unit and/or display unit.During motor operation, fluted disc 30 moves together with machine shaft 10, and photoelectric sensor 50 gathers
The quantity of fluted disc 30 external teeth and then obtain the rotating speed of fluted disc 30 and export to control unit and/or display unit, fluted disc 30
Rotating speed is exactly the rotating speed of motor；In addition the Spring Card limiting fluted disc 30 position is also had on machine shaft 10, Spring Card is by fluted disc 30
Position restriction is lived, and to ensure that photoelectric sensor 50 faces the position of fluted disc 30 external teeth all the time, and then ensures the data of collection
Accurate.
Further, installation set 40 downside radially offers through hole 41, and photoelectric sensor 50 is arranged in through hole 41 and sets
There is the locking unit of locking photoelectric sensor 50 position, probe 51 is adjustable with the distance of fluted disc 30.Fluted disc 30 can voluntarily be processed,
According to the profile up-down adjustment photoelectric sensor 50 of fluted disc 30, probe 51 and the distance of fluted disc 30 is made to reach optimal measuring distance,
Then lock.
As shown in figure 1, being provided with bearing end cover 60 outside bearing 20, it is fixed that installation set 40 and bearing end cover 60 pass through seam
Position, bolt 42 sequentially passes through bearing end cover 60, installation set 40 will be affixed to bearing end cover 60 and installation set 40.Seam is positioned with following
Benefit：One axiality being to ensure that installation set 40 and bearing end cover 60, two is by installation set 40 and bearing end cover 60 end face seal,
Three is the function with axially position.
In order to improve safety, outside installation set 40, it is covered with motor enclosing cover 70, motor enclosing cover 70 is by installation set 40, fluted disc 30
All it is hidden in inside it with photoelectric sensor 50, plays the effect of sealing protection, simultaneously these parts as motor itself
A part, compact conformation, be hardly damaged.
Tumbler of the present utility model and static element are not directly contacted with, and greatly improve the reliability of whole device operation
Property.
