Abstract
A driving shaft is a hollow or solid shaft with multiple sections of different diameters, and the shaft includes a transmission end and a knife end. The transmission end is formed on a first-diameter section of the shaft. The transmission end has a first shoulder to which a bearing is mounted. At least one transmission member is connected to the transmission end. The knife end is formed on a second-diameter section of the shaft and has a second shoulder to which another bearing is mounted. A knife is connected to the knife end. The knife end includes a release hole and a tapered hole. At least two grooves are defined in the transmission end and extend toward the knife end for a length. Higher torque is able to be applied to the shaft.
Claims11
A driving shaft apparatus comprising:
- a shaft with multiple sections of different diameters extending from a transmission end to a knife end directly holding a knife, the transmission end formed on a first-diameter section of the shaft, the first-diameter section having a first radius, the transmission end having a first shoulder to which a bearing is mounted, the shaft being rotationally driven by at least one transmission member surrounding and connected to an external surface of the transmission end;
- the knife end formed on a second-diameter section of the shaft, the knife end having a second shoulder to which another bearing is mounted, the knife connected to the knife end, the knife end having a release hole and a tapered hole, and
- at least two grooves defined in the external surface of the transmission end and extending toward the knife end for a length, the first shoulder located at two respective lower ends of the grooves, each of the grooves having a second radius which is smaller than the first radius.
