Abstract
The utility model provides a velocity measurement device. The velocity measurement device mainly comprises a velocity measurement board, an inductor, and a programmable controller, wherein the velocity measurement board can be connected with a rotator assembly of the motor, the inductor cooperates with the velocity measurement board and is connected with the programmable controller. The utility model also provides a motor equipped with the velocity measurement device, wherein the velocity measurement board and the inductor of the velocity measurement device is mounted in the motor. In the embodiment of the velocity measurement device and the motor, a teeth shaped board is disposed in the velocity measurement device, so that designing teeth shape on the rotator is avoided, thus design is simplified, the structure is made more compact, processing is made more convenient, and cost is reduced; the motor, which is equipped with the velocity measurement device, is more compact in structure and convenient to dismount and maintain.
Description
Technical field
The utility model technology relates to speed measuring device and motor, refers more particularly to motor speed measuring device and the motor that this speed measuring device is housed.
Background technology
In the prior art, motor rotary speed measurement mechanism is different according to sensing element, inlays magnetic material or rotating parts is made to the forms such as gear on rotating parts.It is easily to adsorb iron filings that rotating parts is inlayed magnetic material weak point, causes hydraulic fault, needs in addition larger installing space; It is the size that has increased part that rotating parts is made gear deficiency, and the volume of product is large, complex structure is compact not, inconvenient repair demolition.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned deficiency, design a kind of new induction installation, simplify product design manufacture, convenient for maintaining dismounting, adopt nonmagnetic substance, can be applicable to the inner use of hydraulic product, can not adsorb iron filings and cause hydraulic pressure clamping stagnation, the speed measuring device reducing production costs and the motor that this speed measuring device is housed.
The utility model solves the technical scheme that its technical problem adopts: a kind of speed measuring device, mainly comprises velocity measurement plate, inductor, Programmable Logic Controller; Velocity measurement plate can be connected with the rotor assembly of motor, and inductor coordinates and is connected with Programmable Logic Controller with velocity measurement plate.
Described velocity measurement plate is castellated plates, and the periphery of castellated plates is provided with tooth.
Described inductor is arranged in the induction region of castellated plates peripheral teeth.
A motor for speed measuring device is housed, and the velocity measurement plate in described speed measuring device or castellated plates, inductor are installed on the inside of motor.
In technique scheme, castellated plates can be fixed on the outside of rotor assembly, also can be fixed on the rotor assembly of motor inside, during revolution, drive castellated plates synchronously to rotate, transducer is fixed on housing and coordinates with castellated plates, in the induction region of the tooth of castellated plates periphery in inductor, it is connected near profile of tooth and with Programmable Logic Controller register, after switching on power, at inductor head, produce an alternating magnetic field, when when revolution, castellated plates enters this magnetic field, metal inside induction produces eddy current, this field weakening; When castellated plates shifts out this magnetic field, this magnetic field is recovered original intensity and is exported corresponding signal, by Programmable Logic Controller computing, is controlled.
The beneficial effects of the utility model are that this speed measuring device is provided with a castellated plates, have avoided design tooth profile on rotor, make design simplification, and compact conformation is easy to process, cost; The motor of this speed measuring device is equipped with in inside, and structure is compacter, is easy to remove and repair.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model speed measuring device;
Fig. 2 is the structural representation that the utility model is equipped with the motor of this speed measuring device;
Fig. 3 is the structural representation of castellated plates in the utility model.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is further illustrated
If Fig. 2 is the wheeled motor of a kind of inner curve low-speed big, by output shaft, be directly connected with wheel, reach the object that drives vehicle, in operation process, need measurement, regulation speed.In the utility model, be achieved in that by valve plate 10 and join pressure oil to rotor assembly 4, rotor assembly 4 interacts and produces moment of torsion with stator 5, and rotor assembly 4 drives power transmission shaft 1 to rotate, and then drives Vehicle Driving Cycle; Speed measuring device as shown in Figure 1: drive when rotated castellated plates 6 to rotate at rotor assembly 4, transducer 7 produces pulse signal input Programmable Logic Controller 8 and calculates corresponding rotating speed simultaneously.
More concrete operation process is: motor passes into after pressure oil, rotor assembly 4 drives castellated plates 6 synchronously to rotate, transducer 7 is after switching on power simultaneously, head at transducer 7, produce an alternating magnetic field, when rotor assembly 4 drives profile of tooth to enter this magnetic field, metal inside induction produces eddy current, this field weakening, a pulse signal of transducer 7 outputs; When rotor assembly 4 drives profile of tooth to leave this magnetic field, intensity is before recovered in this magnetic field, a pulse signal of transducer 7 outputs; Rotor assembly 4 rotates continuously, and transducer 7 continues output unlike signal, by wire, inputs Programmable Logic Controller 8, through Programmable Logic Controller 8, calculates motor rotary speed (or Vehicle Speed).
Most preferred embodiment of the present utility model is illustrated, and the various variations of being made by those of ordinary skills or remodeling can not depart from scope of the present utility model.
