Abstract
The present invention relates to fork type torque amplification device, gear block is fixed with gear box cover and graduated tile, power transmission shaft and outlet guide rachis it is rotatablely equipped with in gear block, one end at power transmission shaft is fixed with needle dial, and needle dial coordinates with graduated tile, is fixed with disk on power transmission shaft, disk is fixed with straight pin, being fixed with fork plate on outlet guide rachis, offer shift fork breach on fork plate, described straight pin embeds in this shift fork breach；The gear block of corresponding fork plate swinging end two side position is fixed with limit switch.The present invention adds the arm of force to greatest extent, thus realizes the effect that moment of torsion amplifies, and rotates especially auxiliary further by fork plate and adds moment of torsion, it is achieved that the purpose that end is easily stirred.
Description
Technical field
The present invention relates to a kind of torque amplification device, present invention relates especially to a kind of fork type torque amplification device.
Background technology
Moment of torsion is the power making object rotate, and is exactly the size of moment in physics, equal to power and the product of the arm of force.In the diffuser group of high-speed centrifugal fan, owing to the rotation of exit guide blade is by driving at rotating shaft, stress point is at rotating shaft, therefore the arm of force is the least, compressor flow is the biggest, the aerodynamic moment that exit guide blade rotates is the biggest, adds the resistance that frictional force is brought so that the moment of torsion needed for driving motor is the hugest.When motor cannot meet, can realize by increasing driving force, the most both add operating cost and too increased the volume of driving means.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of driving motor using smaller power but can drive the fork type torque amplification device of the fan outlet guide vane teunnion of big model.
The technical scheme provided according to the present invention, described fork type torque amplification device, being fixed with gear box cover and graduated tile on gear block, be rotatablely equipped with power transmission shaft and outlet guide rachis in gear block, the one end at power transmission shaft is fixed with needle dial, needle dial coordinates with graduated tile, power transmission shaft is fixed with disk, disk is fixed with straight pin, outlet guide rachis is fixed with fork plate, offering shift fork breach on fork plate, described straight pin embeds in this shift fork breach；The gear block of corresponding fork plate swinging end two side position is fixed with limit switch.
The axis of described straight pin is 1.2 ~ 1.6:1 to the diameter ratio of the distance between the axis of power transmission shaft with power transmission shaft.
The first self-lubricating bearing it is provided with between power transmission shaft and gear box cover.
The second self-lubricating bearing it is provided with between outlet guide rachis and gear block.
The present invention adds the arm of force to greatest extent, thus realizes the effect that moment of torsion amplifies, and rotates especially auxiliary further by fork plate and adds moment of torsion, it is achieved that the purpose that end is easily stirred.
Accompanying drawing explanation
Fig. 1 is the front view of the present invention.
Fig. 2 is the top view of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
