Abstract
Title of the present utility model is a kind of fan structure with speed measuring function, relates to the fan structure that speed measuring fluted disc is directly installed on the band speed measuring function on fan specifically.It mainly solves current fan with velocity transducer is what to separate, speed measuring fluted disc is arranged on motor shaft, this structure needs motor axial space large, increase motor manufacturing cost, the serious problem that also design of electrical motor scheme can be caused not adopt due to the restriction of motor mounting space, weight, cost.The utility model comprises speed measuring fluted disc and detecting head device, it is characterized in that: speed measuring fluted disc is embedded on the external diameter of fan by endoporus, and detecting head device is arranged on the outside end cap of speed measuring fluted disc or support relative position.The utility model fan and fluted disc is installed as one, and this structure eliminates speed measuring fluted disc and installs axial space, eliminates motor speed measuring device part axial length, alleviates the weight of motor, reduce motor manufacturing cost, improve running reliability of motor.
Description
Technical field
The utility model relates to a kind of fan structure with speed measuring function, relates to the fan structure that speed measuring fluted disc is directly installed on the band speed measuring function on fan specifically.
Background technique
At present, with the motor of speed sensor, fan cooling system, its fan and velocity transducer are what to separate, speed measuring fluted disc is arranged on motor shaft, and so inevitably make the axis of motor increase the thickness of speed measuring fluted disc, this structure not only needs the installing space increasing speed measuring fluted disc, also can increase the weight of speed measuring fluted disc, increase motor manufacturing cost, poor reliability, serious also can cause design of electrical motor scheme not adopt due to the restriction of motor mounting space, weight, cost.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and the one provided is safe and practical, can reduce motor volume, alleviate motor weight, reduce the fan structure of the band speed measurement device of motor cost.
Technical solution of the present utility model is: comprise speed measuring fluted disc and detecting head device, it is characterized in that: speed measuring fluted disc is embedded on the external diameter of fan by endoporus, and detecting head device is arranged on the outside end cap of speed measuring fluted disc or support relative position.
Fan and fluted disc are installed as one by the utility model dexterously, speed measuring fluted disc is arranged on the outer surface of fan by the utility model, detecting head device is arranged on fluted disc outside, this structure eliminates speed measuring fluted disc and installs axial space, eliminate motor speed measuring device part axial length, alleviate the weight of motor, reduce motor manufacturing cost, improve running reliability of motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, speed measurement device of the present utility model is fixedly mounted on end cap or support by detecting head device 1, forms velocity transducer by detecting head device 1 and the speed measuring fluted disc 2 be fixedly mounted on end cap or support; Speed measuring fluted disc 2 is embedded on the outer surface of fan 3, on fan 3 cylindrical, specifically leave the mounting point of speed measuring fluted disc 2, be arranged on the external diameter of fan 3 after being strengthened by speed measuring fluted disc 2 endoporus, this structure can save the axial length of motor speed measuring device part, alleviates the weight of motor; Detecting head device 1 is arranged on the outside end cap of speed measuring fluted disc 2 or support relative position.
Working principle: in motor operation course, namely motor speed is the rotating speed of fan 3, velocity transducer is fixed by speed measuring fluted disc 2 and fan 3, namely the rotating speed of fan 3 is the rotating speed of speed measuring fluted disc 2, motor speed can be obtained identical with speed measuring fluted disc 2 rotating speed, the rotating speed of the speed measuring fluted disc 2 that detecting head device 1 detects i.e. motor speed, thus reach the effect that fan has speed measuring function.
Claims (1)
