The flexible shaft is a shaft with low rigidity and flexible and flexible transmission. It is used to connect two axes with different axes and not in the same direction or with relative motion to transmit rotary motion and torque. It can flexibly transfer rotary motion and torque to any position.
4 to 5 layers of steel wire are spirally wound on the central steel wire and adjacent layers of steel wire are twisted in opposite wire bundles. It has a structure similar to a single-twisted wire rope, but with a very short twist distance and a great twist angle, and the outer layer of wire is mostly right-twisted. Also called soft wire rope.
Special equipment is required for twisting the flexible shaft. Welding joints are not allowed in the center wire. The outer wire must be deformed in advance by a pre-deformer. When manufacturing the flexible shaft, the pressure shoe should be pressed tightly. The pressure line tile is made of Cr12 steel. The shaft is required to be tight and flat when the shaft is driven, and the broken wire in the production process allows welding.
In mechanical design, it is used as a non-linear transmission or a non-same plane transmission component. It can simplify the transmission machinery, at the same time, the transmission accuracy is high, and the use of a wide range of departments, such as concrete vibrators, wind picks, marine water pumps, medical appliances And the transmission of the machine tool, the car’s odometer can be driven by flexible shafts. In addition, the soft shaft can also reduce the impact.
