Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention:
as shown in fig. 1-4, a disconnect-type square head flange axle rudderstock forging, including the upper rod body 1 and the lower rod body 2, the upper rod body is the forging with the lower rod body, the upper end of the upper rod body is equipped with square head flange board 3, and its lower extreme is equipped with connecting portion 4, the lower end of the lower rod body is used for being connected fixedly with marine screw, and its upper end is equipped with can dismantle the lower connecting portion 5 of being connected with the upper connecting portion, the upper connecting portion can be dismantled with lower connecting portion through the connecting piece and be connected fixedly. In this embodiment, for improving the connection steadiness, go up connecting portion and set up to the picture peg, connecting portion set up to cylindric down, and open at its middle part has and supplies picture peg male slot 6, and when going up the picture peg and inserting in the slot, go up connecting portion and lower connecting portion and form complete columnar structure, therefore, can be comparatively convenient with connecting portion and lower connecting portion connect fixedly, and the picture peg of platykurtic and the structure of slot can effectively improve the torsion transmission intensity of axle rudderstock when the transmission in addition, avoid appearing cracked problem, structural strength is high.
In this embodiment, in order to further improve structural strength, the outer diameter of the columnar structure is greater than the diameters of the upper rod body and the lower rod body.
In addition, for the steadiness of improving the connection, be equipped with the multiunit on the cylinder of the slot both sides of connecting portion down and link up both screw thread punch combination, screw hole 7 on the screw thread punch combination radially sets up along columnar structure, go up the picture peg middle part and be equipped with a plurality of through-holes 8 that a plurality of and screw thread punch combination correspond, pass the screw hole and the through-hole of screw thread punch combination through bolt fastening spare 9 and then will go up the picture peg and be connected fixedly with connecting portion down, through bolt fastening spare, can make things convenient for installation and dismantlement between connecting portion and the lower connecting portion.
