Wherein, the spline in described sharf union end connection slot is located at the footpath perpendicular with the pin of this union end upwards.
Wherein, the keyway in the middle of described on a connection part of coupling spindle and the mutual vertical setting of the keyway on another connection part.
Wherein, the spline in described sharf union end connection slot is provided with two of axle center symmetry.
Wherein, the cross sectional shape of described spline is arc, and arc place circle diameter equals the diameter of connection slot, and the arc of bow-shaped cross-section is less than semicircle.
Wherein, described suspention bearing shell by two semi-round retaining sleeves, be located at the bearing shell in the middle of two retaining sleeves and form with the suspension rod that retaining sleeve is fixedly connected; Suspension rod is located at footpath that two retaining sleeves fasten the annulus forming upwards; The clamp port two ends of retaining sleeve are respectively provided with a flange journal stirrup, and a pair of flange journal stirrup of the bottom of suspension rod and two retaining sleeves is fixedly connected.
The beneficial effect that adopts technique scheme to produce is:
Sharf of the present utility model adopts pin to connect with middle coupling spindle and the comprehensive and connecting mode of key connecting, has solved that single pin draw bail transmitting torque is little, the disadvantage of easy inefficacy, makes multistage sharf can realize long period failure-free operation.The split retaining sleeve of suspention bearing shell is left and right clamping, has avoided carrying the situation that clamps up and down backgauge while being clamminess material.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figures 1 to 4, the rotating shaft that the utility model is a kind of conveyor screw, comprises the multistage sharf 1 of coaxial setting and is located at the middle coupling spindle 2 between two sections of sharfs 1; Middle coupling spindle 2 is made up of holding part 2-1 and two connection part 2-2,2-3 being located at holding part 2-1 two ends; The upper cover of holding part 2-1 has suspention bearing shell 3; On the connection end face of sharf 1, offer axial connection slot, two connection part 2-2, the 2-3 of middle coupling spindle 2 are inserted in respectively in corresponding connection slot, and the union end of the sharf 1 that is inserted in it of connection part 2-2,2-3 is fixedly connected by pin; In the middle of described, on the connection part 2-2 of coupling spindle 2,2-3 outside face, offer axial keyway, in the connection slot that the connection part of this centre coupling spindle 2 is inserted in, be provided with the spline 4 matching with keyway; And the spline 4 in a union end connection slot of sharf 1 is located at the footpath perpendicular with the pin of this union end upwards, the keyway on a connection part of middle coupling spindle 2 and the vertical setting mutually of the keyway on another connection part.
As shown in Figure 2,3, the spline 4 in sharf 1 union end connection slot is provided with two of axle center symmetry; And the cross sectional shape of spline 4 is arc, and arc place circle diameter equals the diameter of connection slot, and the arc of bow-shaped cross-section is less than semicircle.On concrete manufacture, middle coupling spindle 2 is selected 45# steel, and it is arc stick that two cross sections are not cut away to line cutting in the two ends of 45# steel; On a union end connection slot of sharf 1, bore three welding-on holes, two arc stick welding-ons that cut away, in connection slot, are become to 180 ° and are arranged symmetrically with.Therefore, adopt above-mentioned arc spline, key connecting area of contact is large, coordinate closely, and the flow process of processing and manufacturing is simple, cost is low.The comprehensive connecting mode that adopts pin and key between the utility model middle period bobbin 1 and middle coupling spindle 2 has broken up the torque of transmitting, therefore better reliability on orthogonal both direction.
