Abstract
The utility model discloses a farming machine gearbox case which comprises an outer case. An input shaft hole and an output shaft hole are formed in the outer case. The outer case is an aluminum alloy casting. An installing hole is formed in an upper pulling core of the aluminum alloy casting. A reinforcing rib is transversely arranged outside the aluminum alloy casting. The wall thickness of the aluminum alloy casting is 4mm. The farming machine gearbox case is simple in structure, light in weight, low in cost, and little in follow-up amount of finish.
Description
Technical field
The utility model relates to a kind of agricultural ploughing machine gear box casing, belongs to the agro-farming mechanical field.
Background technique
The raw material that existing agricultural ploughing machine gear box casing adopts are cast iron, and wall thickness 〉=6mm, its shortcoming is: at first, cast iron density is 7.8(gram/cubic centimetre), it is bigger to make that gear box casing is assembled in the agricultural ploughing machine weight, and is unfavorable for mechanical light-weight design; Secondly, the wall of gear box casing is thicker, and it is many to expend raw material; Again, also need to get out mounting hole after the existing cast iron gear box casing blank moulding.
The model utility content
The utility model is intended to provide lighter weight, agricultural ploughing machine gear box casing that consumptive material is few.
The purpose of this utility model can reach by following measure: a kind of agricultural ploughing machine gear box casing, comprise shell, have input shaft bore and output shaft hole on the shell, described shell is aluminium alloy castings, the mounting hole of loosing core on this aluminium alloy castings, described aluminium alloy castings outer lateral is to being provided with stiffening rib, and the wall thickness of aluminium alloy castings is 4mm.
The technique scheme difference with the prior art is: at first, original cast iron housing is replaced to aluminium alloy castings, the lighter weight of aluminum alloy has alleviated the weight of housing, is convenient to mechanical light-weight design; Secondly, the wall thickness of aluminium alloy castings is reduced into 4mm, has saved the aluminium alloy compression casting raw material, has further alleviated the weight of housing; Again, the aluminium alloy castings outer lateral has increased the intensity of shell to being provided with stiffening rib; In addition, because the mounting hole of loosing core on the aluminium alloy castings, follow-up needs tapping gets final product, and reduced the following process amount of housing.
The utility model is simple in structure, weight is lighter, with low cost, the following process amount is little.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model agricultural ploughing machine gear box casing embodiment's structural representation.
Embodiment
With reference to Fig. 1, a kind of agricultural ploughing machine gear box casing, comprise the shell 1 that aluminum alloy is made, this shell 1 is aluminium alloy castings, have input shaft bore and output shaft hole on the aluminium alloy castings, loosing core on this aluminium alloy castings has mounting hole 3, and this aluminium alloy castings outside is horizontally connected with the stiffening rib 2 of projection, and the thickness of this aluminium alloy castings is 4mm.
Because original wall thickness 〉=6mm of shell 1 has been become 4mm, saved the aluminium alloy compression casting raw material, further alleviated the weight of housing; In addition, stiffening rib 2 can increase the intensity of shell, and the mounting hole 3 of loosing core has in advance also reduced the boring step in the following process.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
Claims (1)
