Abstract
To simplify composition and enable production cost reduction and mass production by utilizing a motor rotary shaft as a rotary encoder shaft, upper and lower plates as rotary discs and incorporating encoder mechanism in a body with fans. Magnets 5 are mounted on the outside edge of a subplate 2 and magnetism sensors 6 are provided in the vicinity of and for the magnets 5. And ray passage holes 7 and 7 of proper size are provided in alignment on the outside edge of upper and lower plates 1 and 2. A light emitting element 8 is set in a ray hole 7, and a light receiving element 10 is set in another ray hole 7 through a fixed disk 9. The rotary shaft 11 of a motor M is utilized as a rotary encoder shaft, and upper and lower plate 1 and 2 are as rotary discs. The practical manufacture of encoder fans with an encoder mechanism incorporated in the composition of motor direct-coupled fans enables simple composition, production cost reduction, and mass production.
Description
The invention relates to turbofan with sensor mechanism.
The open clear 56-8552(A of communique of Japan Patent) a kind of revolution detector of turbosupercharger is disclosed.Its magnetic-type sensor is arranged on turbofan is fixed on the nut in the rotating shaft.In addition, the open clear 57-200831 of communique of another piece Japan Patent also discloses a kind of turbofan.The optical sensor that this fan had is to be contained on the outstanding position of maximum diameter place blade of turbofan.The turbofan of above-mentioned prior art is textural all complicated.
The object of the present invention is to provide a kind of turbofan with magnetic-type or optical sensor simple in structure.The fan of when constituting fan sensor being packed into forms an integral body, the turbofan of prior art is simplified, to reduce cost suitable a large amount of production.
The present invention is provided with magnetic-type on the front and rear cover plate by turbine or optical sensor is reached.
Fig. 1 is the planimetric map of turbofan, and Fig. 2 is the front elevation of this turbofan, expresses the magnetic-type sensor mechanism, and Fig. 3 is the planimetric map of the demifacet of turbofan, and Fig. 4 is its sectional view, expresses optical sensor mechanism, and Fig. 5 is a Block Diagram.
Now with reference to the accompanying drawings an embodiment is illustrated, a kind of as shown in Figure 2 turbofan, at up and down discoideus front shroud (1) and have between the back shroud (2) of central opening polylith blade (3) is housed, the central part at cover plate is fixed with nave boss.As shown in Figure 1, load onto magnet (5) in the outside of back shroud (2), in place magnetic quantity transducer (6) is housed near this magnet, among Fig. 4, in front and rear cover plate (1), (2) the outside, same position in a straight line is provided with the luminous original paper (8) of the loophole (7) of suitable size by a side of this loophole, with the disk that is fixed in an other side (9), photo detector (10) is set, the running shaft (11) of motor M as the turn-sensitive device axle, and has been constituted present embodiment with the front and rear cover plate of fan as rotating disk.
The present invention as mentioned above, with existing different in the way that has on the fan of motor in addition the sensor device be combined into that will make, but when the direct binding of formation has the fan of motor, sensor mechanism is packed into, in assembling work, very simple, its make efficiency is quite reasonable.When making, at first, in the situation of magnetic encoder, as shown in Figure 1, outer circumference at back shroud (2) (also can in the outside of front shroud) is loaded onto two magnet (5), also multi-pole magnet SN can be set, and in the place near this magnet sensor (6) is set.Shown in the Block Diagram of Fig. 5,, and this is controlled by feedback signal by the revolution of sensor fan.And for example shown in Figure 4, in the situation of optical sensor,, loophole (7) is set in the outside of front and rear cover plate, side up and down at this loophole is provided with light-emitting component (8), by fixed disc, photo detector (10) is set, the opposing party with this optical sensor, receive light by loophole (7), thereby detect the revolution of fan, and this is rotated control by feedback signal, this program is shown in the Block Diagram of Fig. 5.
Claims (1)
1, a kind of turbofan with sensor mechanism of magnetic-type or optical profile type, it is characterized in that, at the front shroud that constitutes turbofan or the outer circumferential side of back shroud 2 utmost points or multi-pole magnet are set, in place magnetic quantity transducer is set near this magnet, by the revolution of this magnetic quantity transducer with the detection fan, or in the end of front shroud or back shroud, the loophole of suitable size is set on the straight line of the upper edge, a position of front and rear cover plate at least, side at this loophole, light-emitting component is set, by fixed disc photo detector is set the opposing party, running shaft with motor is the turn-sensitive device axle, and with the cover plate is rotating disk, directly sensor mechanism is fit in the fan, to detect the revolution of fan.
