Abstract
The utility model relates to a large-sized spiral bevel gear shaft which comprises a bevel gear and a bevel gear shaft and is characterized in that the inner bore of the bevel gear and the neck journal of the bevel gear shaft matched with the inner bore are provided with key slots, a connection key with a length of 250mm and a width of 45mm is embedded in the inner bore of the bevel gear, and the bevel gear is connected with the bevel gear shaft with the connection key. The parts of the large-sized spiral bevel gear shaft are processed independently, the large-sized spiral bevel gear shaft has a length of over 1200 mm, and the positioning shaft journal of the input bevel gear shaft has a diameter of more than 200 mm and a module of 20-30 mm. The teeth of the bevel gear are made of 17CrNiMo6 steel, and the shaft part is 42CrMoA quenched and tempered steel. The respective processed teeth and shaft are connected through the connection key and assembled to an integrated large-sized input bevel gear shaft, thereby the process cost is lowered, and the process cycle is shortened. The large-sized spiral bevel gear shaft has simple structure and can satisfy the requirement of large specification and high accuracy.
Description
Technical field
The utility model relates to a kind of helical bevel gear axle, and more particularly, it relates to a kind of helical bevel gear axle that is used for the big machinery uni-drive gear box.
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 core component in the speed reducer---helical bevel gear, also develop by force to big specification, highi degree of accuracy, bearing capacity.But the machining large helical bevel gear needs large-scale spiral bevel 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 helical bevel gear axial screw bevel gear mill teeth machine and the gear grinding machine of 20～30mm.So the gear set specifications that provides is all less.The heat treatment process difficulty of the integrated type helical bevel gear axle that next is large-scale, and quality is wayward, the cost height.The 3rd, bevel 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.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes existing integrated type helical bevel gear axle, provide a kind of simple in structure, be easy to manufacturing, the large-scale spiral bevel gear shaft that specification is big, precision is high, bearing capacity is strong.
The utility model takes following technical proposals to realize this purpose:
Include bevel gear, bevel gear shaft is characterized in that: the axle journal of endoporus of described bevel gear and the bevel gear shaft that matches with this endoporus is provided with keyway, and the bevel gear endoporus also is embedded with long 250mm, the connecting key of wide 45mm, bevel gear is connected by connecting key with bevel gear shaft.
Adopt large-scale spiral bevel gear shaft of the present utility model, part is independently processed, and axial length can reach more than the 1200mm, more than the input bevel gear shaft locating journal diameter 200mm, and modulus 20～30mm.Bevel 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 by connecting key is connected with axle, always dresses up the large-scale input bevel gear shaft 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 a structural representation of the present utility model.
Among the figure 1, bevel gear, 2 bevel gear shafts, 3, connecting key, 4, keyway.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described in further detail.
The utility model is made of bevel gear 1 and bevel gear shaft 2, the maximum outside diameter 494.77mm of bevel gear 1, and modulus 22.61mm, the number of teeth 20, long 1377mm, maximum axle journal diameter 220mm, bevel gear tooth portion adopts 17CrNiMo6 steel, carburizing and quenching.Axial region adopts 42CrMoA Hardened And Tempered Steel, and bevel gear 1 and split bevel gear shaft 2 are processed respectively.The axle journal of bevel gear 1 endoporus and the split bevel gear shaft 2 that matches with this endoporus is provided with keyway 4, bevel gear 1 endoporus is embedded with long 250mm, the connecting key 3 of wide 45mm is packed bevel gear 1 interference fit that processes in the axle journal keyway 4 of split bevel gear shaft 2 into by connecting key 3.Length overall 1403mm after the general assembly.Form a large-scale input bevel gear shaft of integrated type.Present embodiment is just routine one by one, can also make all size as required.
