The diameter of the head end of described rotating shaft is greater than rotating shaft by the linkage section of interference fit holding at the inner ring of bearing, the head end of rotating shaft is pressed against on the exterior edge face of the inner ring of bearing, between the linkage section of rotating shaft and connecting end, there is the section of being spirally connected, fixing swivel nut is screwed onto in the section of being spirally connected, and the exterior edge face of fixing swivel nut is pressed against on the interior edge face of the inner ring of bearing.

The internal end surface of described outer end cap is fixed with self-lubricating abrasion-resistant layer, self-lubricating abrasion-resistant lamination leans against on the end face of the head end of rotating shaft.

The internal end surface of described inner end cap is fixed with self-lubricating abrasion-resistant circle, the interior edge face of fixing swivel nut is pressed against on self-lubricating abrasion-resistant circle.

Before the internal thread that the madial wall at the connection bump circle of described axial hole and the two ends of axial hole has, there is annular groove, the sidewall of annular groove sprinkles and is bolted with multiple bulb plunger, the steel ball of bulb plunger stretches out annular groove, outer end cap has the shrinkage pool corresponding with bulb plunger with on the outer side wall of inner end cap, and the steel ball of bulb plunger is nested in corresponding shrinkage pool.

Outstanding effect of the present invention is:

Compared with prior art, its bearing adopts plug bush type to fix, and is fixed, makes its bearing removal easy for installation, greatly improve its replacing speed and effect by raised item and strip groove.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present invention;

Fig. 2 is partial sectional view of the present invention.

Embodiment:

Embodiment, see as shown in Figure 1 to Figure 2, a kind of Simple detachable formula rotary roller, comprise wheel body 10, the outer side wall of described wheel body 10 has race 11, the middle part of wheel body 10 has axial hole 12, the middle part sidewall of axial hole 12 has connection bump circle 13, the madial wall of connection bump circle 13 has multiple raised item 131, bearing 20 sleeve is in connection bump circle 13, in the strip groove 21 of the correspondence that raised item 131 sleeve has on the outer side wall of the outer ring of bearing 20, rotating shaft 30 is fixed in the inner ring of bearing 20, the madial wall at the two ends of axial hole 12 has internal thread, outer end cap 14 and inner end cap 15 are screwed onto in the internal thread of the end of corresponding axial hole 12 respectively, the connecting end of rotating shaft 20 stretches out inner end cap 15.

Further, the diameter of the head end of described rotating shaft 30 is greater than rotating shaft 30 by the linkage section of interference fit holding at the inner ring of bearing 20, the head end of rotating shaft 30 is pressed against on the exterior edge face of the inner ring of bearing 20, there is between the linkage section of rotating shaft 30 and connecting end the section of being spirally connected 31, fixing swivel nut 32 is screwed onto in the section of being spirally connected 31, and the exterior edge face of fixing swivel nut 32 is pressed against on the interior edge face of the inner ring of bearing 20.
