Abstract
The utility model discloses a flat belt flow-forming tensioning wheel, and belongs to the technical field of transmission devices. The flat belt flow-forming tensioning wheel comprises an upper edge, a wheel rim, a lower edge and spokes, the upper edge, the wheel rim, the lower edge and the spokes are formed integrally in a flow forming mode, the upper edge and the lower edge are arranged on the two sides of the wheel rim respectively, the spokes are connected on the middle portion of the wheel rim, and a shaft sleeve is connected to the inner sides of the spokes. The tensioning wheel has the advantages that the surface making contact with a belt is smooth, and good in finish degree, and the service life of the belt is prolonged; a belt groove and the spokes are integrated, therefore, the tensioning wheel is good in intensity, and attractive in appearance; the tensioning wheel is formed through flow forming, and therefore the tensioning wheel is good in balance performance; a bearing is fixed through clamping rings, and therefore the bearing is convenient to replace and low in maintenance cost. Therefore, the flat belt flow-forming tensioning wheel has wide application prospect in the field of agricultural machines.
Description
Technical field
The utility model belongs to the transmission device technical field, is particularly related to a kind of flat belt spinning Idle wheel.
Background technique
Flat belt Idle wheel in farm machinery, as shown in Figure 2, the structure that generally adopts two and half cincture riveted joints to form.Adopt such structure, can cause following defect and deficiency:
1. manufacturing procedure is many, the processing technology complexity, and manufacturing efficiency is low;
2. after riveting, greatly, Product Precision is low in distortion, and, due to two half of surface irregularities of rising as high as the banks of taking turns combination, belt pulley easily weares and teares, and belt life reduces;
3. after bearing assemble, can not dismantle, once quality problems occur, whole part is scrapped, and the after market maintenance cost is high.
The model utility content
The purpose of this utility model is to overcome the above-mentioned defect of mentioning and deficiency, and a kind of flat belt spinning Idle wheel is provided.
The utility model realizes that the technological scheme of its purpose employing is as follows.
A kind of flat belt spinning Idle wheel, comprise the integrated top edge of spinning, wheel rim, lower limb and spoke, and described top edge and lower limb are divided into the wheel rim both sides, and described spoke is connected in the wheel rim middle part, and described spoke inboard is connected with axle sleeve.
Described spoke and axle sleeve welding.
Described axle sleeve is arranged with bearing.
Be arranged with to prevent the axially movable snap ring of bearing on described axle sleeve, described snap ring is arranged at the bearing outside, and described bearing inboard is arranged in axle sleeve.
Owing to adopting said structure, a kind of flat belt spinning of the utility model Idle wheel compared with prior art has following beneficial effect:
1. with the surfacing of belt contact, degree of finish is good, and belt life is extended;
2. belt grooves is an integral body with spoke, and intensity is good, beautiful shape;
3. Idle wheel is by mould pressing, and balance quality is good;
4. bearing is fixed by snap ring, so bearing replacing is convenient, and maintenance cost is low.
Therefore, this flat belt spinning Idle wheel has broad application prospects at agricultural mechanical field.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the existing structure schematic diagram.
In figure: 1-top edge, 2-wheel rim, 3-lower limb, 4-spoke, 5-axle sleeve, 6-bearing, 7-snap ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of flat belt spinning Idle wheel, comprise the integrated top edge 1 of spinning, wheel rim 2, lower limb 3 and spoke 4, and described top edge 1 and lower limb 3 are divided into wheel rim 2 both sides and form belt grooves, described spoke 4 is connected in wheel rim 2 middle parts, and described spoke 4 inboards are connected with axle sleeve 5.Belt grooves is an integral body with spoke 4, and intensity is good, beautiful shape.Mould pressing, balance quality is good.With the surfacing of belt contact, degree of finish is good, and belt life is extended.
Described spoke 4 and axle sleeve 5 welding.Described axle sleeve 5 is arranged with bearing 6.
Be arranged with to prevent the axially movable snap ring 7 of bearing 6 on described axle sleeve 5.As preferably, described axle sleeve 5 is provided with an annular groove, and snap ring 7 is arranged in annular groove.Described snap ring 7 is arranged at bearing 6 outsides, and described bearing 6 inboards are arranged in axle sleeve 5.Bearing 6 can be changed by dismounting snap ring 7, has reduced the maintenance cost of part.
The utility model is illustrated according to embodiment, and under the prerequisite that does not break away from present principles, this device can also be made some distortion and improvement.It should be pointed out that all employings are equal to the technological scheme that the modes such as replacement or equivalent transformation obtain, and all drop in protection domain of the present utility model.
