Preferably, it is provided with pin hole between the flange and the crown of roll ridge, is provided in the pin hole for preventing
State the pin of flange and the crown of roll ridge relative motion.
Preferably, the flange is welded with the crown of roll ridge.
Preferably, between the crown of roll ridge and the shaft rounded corner a diameter of 30 ± 10mm.
Preferably, the nominal diameter of the pin hole is 14-20mm, and the quantity of the pin hole is 1-8.
Preferably, the pin hole is that either the circular cone pin hole pin is straight pin or taper bolt to cylinder pin hole.
Preferably, one end of the shaft be three layers of step structure, and it is ladder-like between junction it is rectangular；It is described
The other end of shaft be two layers of step structure, and it is ladder-like between junction be in arc-shaped.
Preferably, the other end of the shaft offers the keyway for being keyed with wheel hub.
Preferably, the lateral wall of the shaft is provided with wearing layer.
The beneficial effects of the utility model are：The utility model provides a kind of spindle nose, including shaft and flange, the axis
Bar is convexly equipped with the crown of roll ridge around the shaft, and rounded corner transition between the crown of roll ridge and the shaft solves weakness
Stress the problems in excessively collects, and the flange is fixedly connected with the crown of roll ridge, using such structure, makes the shaft and institute
The connection stated between flange is more secured, improves the bulk strength of shaft head structure, reduces between the shaft and the flange
The phenomenon that frangibility, spindle nose fall off in mechanical transmission course, when driving torque is larger also can effectively meet demand, increase
The service life of spindle nose is added.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left view of the utility model.
Reference numeral is：1, shaft；2, flange；3, crown of roll ridge；4, pin hole；5, keyway.
Specific implementation mode
For the ease of the understanding of those skilled in the art, with reference to embodiment and attached drawing 1-2 to the utility model make into
The explanation of one step, the content that embodiment refers to not are the restriction to the utility model.
As shown in Figs. 1-2, a kind of spindle nose, including shaft 1 and flange 2, the shaft 1 are convexly equipped with around the shaft 1
Crown of roll ridge 3, rounded corner transition between the crown of roll ridge 3 and the shaft 1, the flange 2 are fixedly connected with the crown of roll ridge 3.
It solves weakness stress the problems in excessively to collect, using such structure, makes the company between the shaft 1 and the flange 2
It connects more secured, improves the bulk strength of shaft head structure, reduce frangibility, spindle nose between the shaft 1 and the flange 2 and exist
The phenomenon that falling off in mechanical transmission course, when driving torque is larger also can effectively meet demand, increase making for spindle nose
Use the service life.
The flange 2 and the crown of roll ridge 3 interference fit connect, and interference fit is H7/m5 so that the flange 2 with
Large carrying capacity between the crown of roll ridge 3, to absorb impact performance good, and the flange 2 is effectively prevent to be detached with the shaft 1.
It is provided with pin hole 4 between the flange 2 and the crown of roll ridge, is provided in the pin hole 4 for preventing the method
The pin of orchid 2 and 3 relative motion of crown of roll ridge increases between the flange 2 and the crown of roll ridge 3 and sells to bear equipment torque,
Influence of the dispersion torque to weld seam effectively prevent flange 2 described in transmission process that relative motion occurs with the crown of roll ridge 3.
It is welded between the flange 2 and the crown of roll ridge 3, it is preferred that open slope between the flange 2 and the crown of roll ridge 3
Mouth solder design welds fusion depth to increase, and does not influence the welding stress problem of the shaft 1.
A diameter of 30 ± 10mm of rounded corner between the crown of roll ridge 3 and the shaft 1, the preferred crown of roll ridge 3 with
A diameter of 30mm of rounded corner between the shaft 1, can solve weakness stress between the crown of roll ridge 3 and the shaft 1
The problem of excessively concentrating and leading to fracture.
