Abstract
The utility model relates to a belt wheel for agricultural and forestry machines. The belt wheel comprises two wheel hubs with the thickness a half smaller than that of an original belt wheel. A groove of the belt wheel and for containing a belt has an inverted trapezoidal section. The edge on one side of each wheel hub is thinner than the center portion of the wheel hub. The center and the edge of each wheel hub and the belt needing placing form a half of a right trapezoid which is perpendicularly divided along an upper side and a lower side which are parallel into two halves. The two wheel hubs are installed oppositely to form the completed belt wheel. A shaft hole is installed at the center of each wheel hub.
Description
Technical field
The utility model relates to the agriculture and forestry machinery field, is meant that especially a kind of agriculture and forestry machinery uses belt pulley.
Background technique
In the agriculture and forestry machinery field, because of the restriction of operational site, gear transmission and chain transmission are prone to can't use on a large scale because of vibrating big reason, in the agriculture and forestry machinery field, and most of the selection with belt transmission, belt pulley is the critical piece of agriculture and forestry machinery.
In the existing technology, because of will the periphery of wheel hub being machined for the groove of placing belt in the belt pulley course of working, and this groove generally is an employing machining mode as be difficult to processing with the casting technique mould.And mechanical processing technique is complicated, also is unfavorable for utilization ratio of raw materials, can't reduce production costs.
The inventor proposes a kind of improvement technology to this belt pulley to the defective of existing technology, and this technology is used and adopted powder metallurgical technique processing, adopts mould once to suppress and is close to shaping, need not process, and stock utilization is high.
The model utility content
The purpose of the utility model provides a kind of technology, and is complicated with the processing technology that overcomes existing technology, the characteristics that stock utilization is low, and when damaging appears in belt pulley, can be convenient for changing, renewal cost is low simultaneously.
The utility model is realized through following technological scheme.
A kind of agriculture and forestry machinery is used belt pulley; Comprise by two wheel hubs and forming with former half thickness of belt pulley; The belt pulley of said composition is used to place the cross section of groove of belt for trapezoidal, and a side margin of said each wheel hub is thinner than the center portion, and the center of said each wheel hub is formed one with the edge and vertically divided half the right-angled trapezium with the belt section of required placement equally along two parallel edges up and down; Said two wheel hubs are installed relatively, form the pulley groove of a completion; There is installation axle hole at said each wheel hub center.
As further improvement, the groove that said two wheel hubs are formed is used to place belt is a triangle.
The beneficial effect of the utility model is:
Through the patent art scheme, can realize using the casting technique mode to cast, also reduce production costs when enhancing productivity.
Description of drawings
Fig. 1, the plan view of the utility model a slice wheel hub;
Fig. 2, the schematic cross-section of the utility model a slice wheel hub;
Fig. 3, the use condition schematic cross-section of the utility model.
Embodiment
Below in conjunction with the specific embodiment of accompanying drawing detailed description this patent, said embodiment's example is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar parts or the parts with identical or similar functions.Be exemplary through the embodiment who is described with reference to the drawings below, only be used to explain this patent, and can not be interpreted as restriction this patent.
1-is shown in Figure 3 with reference to accompanying drawing, and the embodiment of this patent realizes through following technological scheme:
A kind of agriculture and forestry machinery is used belt pulley; Comprise by two wheel hubs 1 and forming with former half thickness of belt pulley; The belt pulley of said composition is used to place the cross section of groove of belt for trapezoidal, and a side margin of said each wheel hub is thinner than the center portion, and the center of said each wheel hub is formed one with the edge and vertically divided half the right-angled trapezium with the belt of required placement equally along two parallel edges up and down; Said two wheel hubs are installed relatively, form the pulley groove 3 of a completion; There is installation axle hole 2 at said each wheel hub center.
As further improvement, the cross section that said two wheel hubs are formed is used to place the groove of belt is a triangle.
This patent improve one's methods for:
By improving requirement, processing mold is processed said a slice wheel hub shape; In batch mixing with iron powder, plumbago, nickel powder, oiling agent are processed mixed material powder in proportion, ratio is weight percentage, and comprises the nickel of 1.0%-5.0%, the copper of 1.0%-3.0%, the plumbago of 0.5%-0.9%, the oiling agent of 1.0%-5.0%, surplus is an iron powder; With above-mentioned batch mixing under 500-600MPa pressure through the mould press forming, at 1120 ℃ of-1140 ℃ of following sintering, and insulation 30-40 minute is adopted well formula steam treatment stove in the steam treatment operation with grill-hearth travelling oven, furnace temperature 550 is spent 2 hours time.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
