Abstract
The invention discloses a farming machine gear box shell which comprises a shell, wherein an input shaft hole and an output shaft hole are formed on the shell, the shell is an aluminum alloy casting, an installing hole is installed on the aluminum in a loose core mode, a reinforcing rib is installed outside the aluminum alloy casting in a transverse mode, and the wall thickness of the aluminum alloy casting is 4 mm. The farming machine gear box shell is simple in structure, low in weight and cost, and small in subsequent processing amount.
Description
Technical field
The present invention relates to a kind of agricultural ploughing machine gear box casing, belong 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(g/cc), make gear box casing be assembled in agricultural ploughing machine weight larger, and be unfavorable for mechanical light-weight design; Secondly, the wall of gear box casing is thicker, expends raw material many; Again, also need to get out mounting hole after existing cast iron gear box casing blank moulding.
Summary of the invention
The invention is intended to provide lighter weight, agricultural ploughing machine gear box casing that consumptive material is few.
Purpose of the present invention can reach by following measures: a kind of agricultural ploughing machine gear box casing, comprise shell, have input shaft bore and output shaft hole on 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, due to the mounting hole of loosing core on aluminium alloy castings, follow-up needs tapping gets final product, and reduced the following process amount of housing.
The present invention is simple in structure, weight is lighter, with low cost, the following process amount is little.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is agricultural ploughing machine gear box casing embodiment's of the present invention 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 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 the original wall thickness 〉=6mm with shell 1 has 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 is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (1)
1. an agricultural ploughing machine gear box casing, comprise shell, has input shaft bore and output shaft hole on shell, it is characterized in that: 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.
