Embodiment
Mini engine output terminal special belt pulley of the present utility model, as shown in Figure 1, to be combined into one formation primarily of wheel sheet A1 and wheel sheet B2.
Wheel sheet A1 is consisted of punching press global formation primarily of half race 1a and spoke 1a;
Wheel sheet B2 is consisted of punching press global formation half race 2b and spoke 2a; Wheel sheet A1 and wheel sheet B2 specification are equal to.This structure is conventional structure, is not described in detail at this.
The concrete structure of wheel sheet A1 and wheel sheet B2 compound is: spoke 1a and spoke 2a is face-to-face, and concentric compound forms belt wheel.
In order to make the compound of belt wheel more fit, the utility model adds positioning and fastening arrangement 3 on spoke, and positioning and fastening arrangement 3 is arranged on spoke, and with spoke global formation, decrease process step.And in the utility model, the design of positioning device, according to different demands, devises following technological scheme:
Embodiment 1
On the basis of above-mentioned belt wheel, positioning device 3 structure of the present embodiment is as shown in Figure 2: be equipped with center hole 4 at wheel sheet A1 and the wheel set 1a of wheel sheet B2 and the central position of spoke 2a, centered by center hole, the surface of wheel set 1a is all arranged with the positioning spline 1a1 of pair of separated formula female and the positioning key 1a2 of projection; The surface of spoke 2a is all arranged with pair of separated formula positioning spline 2a1 and positioning key 2a2.During assembling, positioning spline 1a1 and positioning key 2a2, positioning spline 2a1 and positioning key 1a2 are fitted together to, and rotary screw is fixedly connected with motor in center hole 4, while fixing, what realize between wheel sheet A1 and wheel sheet B2 is fastening.
The advantage of this structure, for adopting this positioning device, when making wheel sheet, only needs a mould, cost-saving and adopt the ingenious cooperation of positioning key and center hole, and namely reach the effect of location, achieve again compact compound, structure is simple, reasonable in design.
