Abstract
The invention relates to a pulling fork type torque amplifying device. A gearbox cover and a scale plate are fixedly arranged on a gearbox seat, a transmission shaft and an outlet guide blade shaft are rotationally arranged in the gearbox seat, one end part of the transmission shaft is fixedly provided with a dial, the dial is matched with the scale plate, a circular disc is fixedly arranged on the transmission shaft, a cylinder pin is fixedly arranged on the circular disc, a pulling fork plate is fixedly arranged on the outlet guide blade shaft, a pulling fork notch is formed in the pulling fork plate, the cylinder pin is embedded in the pulling fork notch, and a position limiting switch is fixedly arranged on the gearbox seat corresponding to the two side positions of the swinging end of the pulling fork plate. The pulling fork type torque amplifying device has the advantages that the force arm is increased to the maximum degree, so the torque amplification effect is realized, the torque is further increased in an auxiliary way through the rotation of the pulling fork plate, and the goal of easily pulling the tail end is realized.
Description
Technical field
The present invention relates to a kind of torque amplification device, the present invention especially relates to a kind of fork type torque amplification device.
Background technique
Moment of torsion is the power that object is rotated, and is exactly the size of moment in physics, equals the product of power and the arm of force.In the Diffuser group of high-speed centrifugal fan, because the rotation of exit guide blade drives by rotating shaft place, force bearing point is in rotating shaft place, therefore the arm of force is very little, compressor flow is larger, the aerodynamic moment of exit guide blade rotation is also larger, adds the resistance that frictional force is brought, and makes the required moment of torsion of drive motor also very huge.In the time that motor cannot meet, can realize by increasing driving force, so both having increased operating cost has also increased the volume of drive unit.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of fork type torque amplification device that uses the drive motor of smaller power but can drive the fan outlet guide vane teunnion of large model is provided.
According to technological scheme provided by the invention, described fork type torque amplification device, on gear block, be fixed with gear box cover and scale plate, in gear block, be rotatablely equipped with transmission shaft and outlet guide rachis, be fixed with needle dial in an end of transmission shaft, needle dial coordinates with scale plate, on transmission shaft, be fixed with disk, on disk, be fixed with straight pin, on outlet guide rachis, be fixed with fork plate, on fork plate, offer shift fork breach, described straight pin embeds in this shift fork breach; On the gear block of corresponding fork plate swinging end two side positions, be fixed with limit switch.
The axis of described straight pin to the diameter ratio of the distance between the axis of transmission shaft and transmission shaft is 1.2 ~ 1.6:1.
Between transmission shaft and gear box cover, be provided with the first self oiling bearing.
Between outlet guide rachis and gear block, be provided with the second self oiling bearing.
The present invention has increased the arm of force to greatest extent, thereby realizes the effect that moment of torsion amplifies, and is rotated especially and is further assisted and increased moment of torsion by fork plate, has realized the object that end is easily stirred.
