The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an avoid cracked comber draft transmission shaft, includes draft axle, transmission shaft, connector, the input of draft axle, the output cross section of transmission shaft are the rectangle, the inside rectangle through-hole that is used for cup jointing the input of draft axle, the output of transmission shaft of connector, the outside of connector is for surrounding the unclosed face of cylinder behind a week, should unclosed department for along radial intercommunication to the locking groove of rectangle through-hole, the locking groove is provided with the locking bolt.
Preferably, the rectangle of the cross section of the input end of the drafting shaft is an inscribed square of the circumferential surface of the shaft body of the drafting shaft, and the rectangle of the cross section of the output end of the transmission shaft is an inscribed square of the circumferential surface of the shaft body of the transmission shaft.
Preferably, the length of the connector into which the drafting shaft and the transmission shaft extend is greater than 22mm.
Preferably, the connector is provided with two locking bolts, and the two locking bolts are distributed along the axial direction of the drafting shaft.
Preferably, four counter bores are arranged on the side face of the connector and are respectively located at two ends of the two locking bolts.
Preferably, the middle part of the rectangular through hole is provided with a step for limiting the insertion depth of the drafting shaft and the transmission shaft
The utility model has the advantages that: the utility model provides an avoid cracked comber draft transmission shaft, its includes draft axle, transmission shaft, connector, the input of draft axle, the output cross section of transmission shaft are the rectangle, the inside rectangle through-hole that is used for cup jointing of connector the input of draft axle, the output of transmission shaft, the outside of connector is for encircleing the not confined face of cylinder behind a week, should not seal the department for radially communicate to the locking groove of rectangle through-hole, the locking groove is provided with the locking bolt, the utility model discloses the structure science has both made things convenient for the installation of draft transmission shaft to dismantle, and the lifting surface when having improved transmission power again has prolonged the life of draft transmission shaft, avoids its fracture.

Detailed Description
The following detailed description of the present invention is provided with reference to the accompanying drawings and specific embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1 and 2, the breakage-preventing drafting transmission shaft of the combing machine of the embodiment includes a drafting shaft 1, a transmission shaft 2, and a connector 3, cross sections of an input end of the drafting shaft 1 and an output end of the transmission shaft 2 are rectangular, a rectangular through hole 31 for sleeving an input end of the drafting shaft 1 and an output end of the transmission shaft 2 is arranged inside the connector 3, an outer portion of the connector 3 is an unsealed cylindrical surface surrounding a circle, the unsealed portion is a locking groove 32 communicated with the rectangular through hole 31 along a radial direction, the locking groove 32 is provided with a locking bolt 33, the locking bolt 33 can reduce a gap at the locking groove 32, so that the drafting shaft 1 and the transmission shaft 2 are clamped at the rectangular through hole 31, contact areas of the drafting shaft 1 and the transmission shaft 2 with the connector 3 are large, and breakage of the drafting shaft 1 or the transmission shaft 2 due to overlarge torque is avoided.
Further, the rectangle of the cross section of the input end of the drafting shaft 1 is an inscribed square of the circumference surface of the shaft body of the drafting shaft 1, and the rectangle of the cross section of the output end of the transmission shaft 2 is an inscribed square of the circumference surface of the shaft body of the transmission shaft 2.
Furthermore, the length of the drawing shaft 1 and the length of the transmission shaft 2 extending into the connector 3 are both larger than 22mm, so that the connection is reliable and the connector is not easy to break.
Further, the connector 3 is provided with two locking bolts 33, and the two locking bolts 33 are distributed along the axial direction of the drafting shaft 1, so as to better clamp the drafting shaft 1 and the transmission shaft 2.
Furthermore, four counter bores are arranged on the side face of the connector 3, and the four counter bores are respectively located at two ends of the two locking bolts 33, so that the locking bolts 33 can be conveniently detached.
Further, a step for limiting the insertion depth of the drafting shaft 1 and the transmission shaft 2 is arranged in the middle of the rectangular through hole 31.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
