Abstract
The utility model relates to a special electric push rod for a high-speed centrifugal fan, in particular to a special device for regulating inlet-outlet guide blades of the high-speed centrifugal fan. The device consists of a transmission, a transmission seat and a transmission cover, which are assembled into a whole. The front end of the transmission seat is provided with a push rod outer sleeve; the output shaft of the transmission passes through a linkage transmission sleeve and a transmission thread; a push rod is arranged in the push rod outer sleeve; the output shaft of the transmission is provided with a pinion which is joggled with a gearwheel; the gearwheel and a potentiometer are synchronously arranged in the transmission seat; and the transmission is connected with a miniature motor into a whole. As the utility model adopts the miniature motor for speed reduction via the gears and for transmission via a screw pair, the rotary movement of the spindle of the motor can be converted into linear movement of a screw rod (push rod) with a certain speed. Meanwhile, as the device is provided with the potentiometer, the start of the motor is realized by controlling parameters of the potentiometer so as to control the stroke of the push rod. The utility model has the advantages of low cost and convenient maintenance.
Description
Technical field
The utility model relates to a kind of motor push rod special for high speed centrifugal fan, is used for high-speed centrifugal fan specifically and imports and exports the isolated plant that stator is regulated, and belongs to mechanical structure (electromechanical integration) technical field.
Background technique
In prior art, the adjusting of high-speed centrifugal fan import and export stator generally adopts the electric pushrod of standard on the market, the control of push rod stroke to rely on the signal of actuating motor to realize.The electronic pusher body of this type of standard is long-pending bigger, and is very inharmonious with the blower fan main body, and the application of actuating motor makes its manufacture cost higher, and maintenance needs the professional workforce.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of motor push rod special for high speed centrifugal fan is provided, and its volume is little, low cost of manufacture, convenience easy to maintenance.
According to the technological scheme that the utility model provides, motor push rod special for high speed centrifugal fan is assembled into one by speed changer, gearbox adapter and gear shift cover; Front end at gearbox adapter is installed the push rod overcoat, transmission output shaft is by keyed jointing drive sleeve and motion thread, push rod is installed in the push rod overcoat, small gear is installed on transmission output shaft, feature is described small gear and gearwheel engagement, gearwheel and potentiometer are installed in the gearbox adapter synchronously, and speed changer and microminiature motor fuse.
Described microminiature motor is connected with fitting seat.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to adopt the regular micro motor by gear reduction and screw pair transmission, the straight line motion of the screw rod (push rod) that rotatablely moving of electric machine main shaft converted to have certain speed, simultaneously, this device is provided with potentiometer, by the parameter of potentiometer is controlled the startup that realizes motor, thus the stroke of control push rod; Low cost of manufacture, easy to maintenance; Can be exclusively used in the automation control of high-speed centrifugal fan being imported and exported stator.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1: high-speed centrifugal fan special electric screw rod comprises parts such as microminiature motor 1, speed changer 2, transmission output shaft 3, drive sleeve 4, motion thread 5, push rod (screw rod) 6, dust ring 7, small gear 8, gearwheel 9, potentiometer 10, push rod overcoat 11, gearbox adapter 12, gear shift cover 13 and fitting seat 14.
The utility model adopts stay bolt that microminiature motor 1, speed changer 2 are assembled into one with gearbox adapter 12 and gear shift cover 13; In microminiature motor 1 the other end connection seat 14, installing and locating when being used to use; Front end at gearbox adapter 12 is installed push rod overcoat 11, and transmission output shaft 3 drives drive sleeve 4 and motion thread 5 by keyed jointing, and push rod 6 is installed in the push rod overcoat 11, dust ring 7 is installed between push rod overcoat 11 outer ends and push rod 6 is used to prevent dust.Small gear 8 is installed on transmission output shaft 3, small gear 8 and gearwheel 9 engagements, gearwheel 9 is installed in the gearbox adapter 12 synchronously with potentiometer 10.
After microminiature motor 1 starts, make transmission output shaft 3 by certain rotating speed rotation by speed changer 2, transmission output shaft 3 drives drive sleeve 4 by link and screw thread 5 rotates, and converts move up and down (straight line motion) of push rod 6 again to by the rotation of screw drive adjutant screw thread 5.Small gear 8 also rotated synchronously and drives gearwheel 9 and rotates when transmission output shaft 3 rotated simultaneously, this moment, potentiometer 10 changed potential parameters according to the order of sequence with the rotation of gearwheel 9, motor outage when waiting this parameter to reach the numerical value of presetting in the automation control system, push rod 6 stop motions, the stator (not drawing among the figure) that connect with push rod this moment has been adjusted to the position of setting, and the self-locking performance of screw drive pair has been guaranteed the stability of stator adjusted position.
