Abstract
The utility model discloses a spiral bevel gear shaft. The spiral bevel gear shaft comprises a bevel gear and a bevel gear shaft, wherein an inner hole of the bevel gear and a shaft neck of the bevel gear shaft, which is matched with the inner hole, are provided with spline grooves, splines are embedded in the inner hole of the bevel gear, and the bevel gear and the bevel gear shaft are connected by a connecting key. The spiral bevel gear shaft disclosed by the utility model is in independent processing by adopting components, the shaft length can be up to more than 1200 mm, the locating shaft neck diameter of an input bevel gear shaft is more than 200 mm, and the mode number is 20-30 mm. A tooth part of the bevel gear adopts a 17CrNiMo6 steel for quenching by mixing with carbon; and a shaft part of the bevel gear adopts a 42CrMoA hardened and tempered steel, and thus the material cost is lowered. According to the spiral bevel gear shaft disclosed by the utility model, the tooth part and the shaft part which are respectively processed are connected through the connecting key and are then assembled into an integrated type large-scale input bevel gear shaft, thus the processing cost is lowered, the processing period is shortened, the structure is simple, and the requirements of large size and high accuracy can be met.
Description
Technical field
The utility model relates to a kind of gear shaft, is specifically related to a kind of spiral bevel gear wheel shaft.
Background technique
In recent years,, maximize along with the facilities continuous advancement in technology, high efficiency, the big machinery uni-drive gear box of low energy consumption is used widely.As the spiral bevel gear one by one of the core component in the speed reducer, also develop by force to big specification, highi degree of accuracy, bearing capacity.But the machining large helical bevel gear needs large-scale spiral umbrella gear mill teeth machine and gear grinding machine; At present because the restriction of processing technique; The processing diameter is more than 200mm, and length is more than 1200mm, and modulus seldom has at spiral bevel gear axial screw umbrella gear mill teeth machine and the gear grinding machine of 20～30mm.So the gear set specifications that provides is all less.Secondly the heat treatment process of large-scale integrated type helical bevel gear axle is difficult, and quality is wayward, and cost is high.The 3rd, umbrella gear tooth portion need adopt the 17CrNiMo6 steel, costs an arm and a leg, and as adopting integrated type, then cost of material is higher.Be difficult to satisfy the demand of existing weaponry and equipment.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, provide a kind of simple in structure, be easy to manufacturing, the spiral bevel gear wheel shaft that specification is big, precision is high, bearing capacity is strong.
For realizing above-mentioned purpose; The technological scheme of the utility model is a kind of spiral bevel gear wheel shaft of design; Said gear shaft comprises umbrella gear and angular wheel shaft, it is characterized in that, is provided with spline at the axle journal of the endoporus of said umbrella gear and the angular wheel shaft that matches with this endoporus; In said umbrella gear endoporus, also be embedded with spline, bevel gear is connected by connecting key with bevel gear shaft.
Wherein optimized technical scheme is, said spline is the spline of involute formula.
Optimized technical scheme also has, and near the other end of said angular wheel shaft, is provided with axial flat key keyway.
The advantage and the beneficial effect of the utility model are: this spiral bevel gear wheel shaft adopts part independently to process, and axial length can reach more than the 1200mm, more than the input bevel gear axle locating journal diameter 200mm, and modulus 20～30mm.Umbrella gear tooth portion adopts 17CrNiMo6 steel, carburizing and quenching; Axial region adopts 42CrMoA Hardened And Tempered Steel, reduces cost of material.The tooth portion that will process separately through connecting key is connected with axle, always dresses up the large-scale input bevel gear axle of integrated type again, cuts down finished cost, and has shortened the process-cycle.Simple in structure, can satisfy big specification, high-precision requirement.
Description of drawings
Fig. 1 is the structural representation of the utility model spiral bevel gear wheel shaft.
Among the figure: 1, umbrella gear; 2, angular wheel shaft; 3, spline; 4, spline.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
As shown in Figure 1, the utility model is a kind of spiral bevel gear wheel shaft, and this spiral bevel gear wheel shaft includes umbrella gear 1 and angular wheel shaft 2; The maximum outside diameter 494.77mm of umbrella gear 1, modulus 22.61mm, the number of teeth 20, long 1377mm, maximum axle journal diameter 220mm, umbrella gear tooth portion adopts the 17CrNiMo6 steel, and carburizing 3 is quenched.Axial region adopts 42CrMoA Hardened And Tempered Steel, and umbrella gear 1 is processed respectively with split angular wheel shaft 2.The axle journal of umbrella gear 1 endoporus and the split angular wheel shaft 2 that matches with this endoporus is provided with spline 4, and umbrella gear 1 endoporus is embedded with spline 3, and the umbrella gear that processes 1 interference fit is packed in the axle journal spline 4 of split angular wheel shaft 2 by spline 3.Length overall 1403mm after the general assembly forms a large-scale input bevel gear shaft of integrated type.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
Claims (3)
1. spiral bevel gear wheel shaft; Said gear shaft comprises umbrella gear and angular wheel shaft; It is characterized in that; Axle journal at the endoporus of said umbrella gear and the angular wheel shaft that matches with this endoporus is provided with spline, in said umbrella gear endoporus, also is embedded with spline, and bevel gear is connected by connecting key with bevel gear shaft.
2. spiral bevel gear wheel shaft as claimed in claim 1 is characterized in that, said spline is the spline of involute formula.
