Abstract
The utility model discloses a belt pulley. The belt pulley includes a pulley body; a flange coaxially connected with one side of the pulley body; a support cylinder coaxially connected with the other side of the pulley body; a support boss disposed at outer end part of the support cylinder; a steel outer ring disposed on outer circumference of the pulley body and in interference fit with the pulley body; and belt teeth disposed on the outer ring. By such configuration, belt pulley can be easily dismantled by screw extractor without damaging the outer ring and belt teeth.
Description
Technical field
The utility model relates to a kind of belt pulley, belongs to field of mechanical technique.
Background technique
Usually adopt key, jackscrew or locking nut that belt pulley and transmission shaft are fixed together between conventional belt wheel and the transmission shaft, strong groove is easy to wear, working life short, the maintenance frequent through reaching with the fixing belt pulley endoporus of upper type, transmission shaft, key; Especially belt pulley and transmission shaft surface of contact cause surface of contact surface friction drag to increase after getting rusty under the effect of water and oxygen, and be relatively more difficult with conventional method for dismounting dismounting, when adopting bearing to draw horse to dismantle, also damages the belt teeth on the belt pulley outer ring easily.
The model utility content
The technical problem that the utility model will solve is to above deficiency, and a kind of belt pulley is provided, and the belt teeth of this belt pulley is not fragile, and dismounting easily.
For solving the above problems; The utility model adopts following technological scheme: a kind of belt pulley, comprise pulley body, and a side of pulley body is coaxially connected with flange; It is characterized in that: the opposite side of said pulley body is coaxially connected with the support tube, and the outer end of support tube is provided with support rim.
Further improvement as technique scheme:
The excircle of said pulley body is provided with the outer ring of steel, outer ring and pulley body interference fit, and the outer ring is provided with belt teeth.
The utility model is taked above technological scheme, compared with prior art, has the following advantages: the steel outer ring with the pulley body interference fit is set on the excircle of pulley body; And the support tube of coaxial connection is set, and in the outer end of support tube support rim is set, just can be with drawing horse like a cork belt pulley to be taken off, and can not damage outer ring and belt teeth.
The utility model is described further with implementing below in conjunction with accompanying drawing.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment middle belt pulley;
The 1-pulley body, the 2-outer ring, the 3-belt teeth, 4-flange, 5-support tube, 6-support rim.
Embodiment
Embodiment, as shown in Figure 1, a kind of belt pulley; Comprise pulley body 1, the excircle of pulley body 1 is provided with the outer ring 2 of steel, outer ring 2 and pulley body 1 interference fit; Outer ring 2 is provided with belt teeth 3; One side of pulley body 1 is coaxially connected with flange 4, and the opposite side of pulley body 1 is coaxially connected with support tube 5, and the outer end of support tube 5 is provided with support rim 6.
When needing the dismounting belt pulley, will draw horse to be enclosed between support tube 5 and the transmission shaft, the leading screw of horse is drawn in rotation, because the effect of support rim 6 and leading screw just can be taken off belt pulley like a cork, and can not damaged outer ring 2 and belt teeth 3.
Claims (2)
1. belt pulley; Comprise pulley body (1); One side of pulley body (1) is coaxially connected with flange (4), it is characterized in that: the opposite side of said pulley body (1) is coaxially connected with support tube (5), and the outer end of support tube (5) is provided with support rim (6).
2. a kind of belt pulley as claimed in claim 1 is characterized in that: the excircle of said pulley body (1) is provided with the outer ring (2) of steel, outer ring (2) and pulley body (1) interference fit, and outer ring (2) are provided with belt teeth (3).
