Background technology
Moment of torsion is the power for making object rotate, and is exactly the size of torque in physics, equal to power and the product of the arm of force.
In the diffuser group of monopole centrifugal blower, since exit guide blade is rotated by being driven at shaft, it is necessary to bear out
The mouth rotating aerodynamic moment of guide vane, will also bear the resistance that the frictional force at each position is brought so that the moment of torsion needed for driving motor
It is very big, when motor can not meet torque demand, it can be realized by middle increase actuator moment of torsion, so both reduce fortune
Row cost, also saves installation operation space.
The power attenuation very little of gear engagement, can be ignored herein, can be considered and transmits moment of torsion, power by gear
Remain unchanged, and rotating speed reduces, then has haveed the function that to increase moment of torsion.

Second self-lubricating copper sheathing, pinion shaft, interior hexagonal connection bolt, scale plate, needle dial, interior hexagonal connection bolt；The diffusion
Device shaft one end couples gear wheel, the diffuser system inside diffuser shaft other end connection；The pinion shaft leads to
Cross square hole to be connected with actuator, actuator moment of torsion, by external toothing, is passed to diffuser by the pinion shaft with gear wheel
Shaft；Fix scale plate on the spring bearing cover board, one end concatenation pointer disk in the diffuser shaft, is connected with interior hexagonal
Needle dial is pressed in diffuser shaft by bolt；The diffuser shaft is connected by key with gear wheel；First self-lubricating
Copper sheathing is coordinated by transition to be installed on spring bearing；The second self-lubricating copper sheathing is coordinated by transition is installed to spring bearing
On, the pinion shaft is installed in the second self-lubricating copper sheathing；The spring bearing connects bolt by interior hexagonal and is installed to tooth
On roller box tank wall.
Preferably, the pinion shaft transmits moment of torsion with diffuser shaft by the gear of external toothing.
Preferably, the pinion shaft is connected with actuator by square hole.
Preferably, the no-load voltage ratio of the pinion shaft and gear wheel is 2:1~4:1.
Compared with prior art, the beneficial effects of the invention are as follows：Present inventive concept is ingenious, simple in structure, all parts it
Between coordinate compact, by the engagement system of big pinion gear, not only effectively avoid the deficiency of the installation space after actuator directly fills,
And the moment of torsion of actuator can be effectively increased, reduce the purchase cost of actuator.
