Description
Technical field
The present invention relates to gear wheel technical field.
Background technology
As shown in figure 1, gear wheel middle gear of the prior art is structure as a whole with wheel hub, outer gear rim is a diameter of
3200mm, hub thickness is 1000mm, and being processed manufacture with solid forging forms, and forging material is 34CrNi3Mo, the material
Utilization rate is low, and processing cost is very high.
The content of the invention
The technical problem to be solved in the present invention is：There is provided a kind of welding gear wheel, it is easy to make, cost is relatively low.
The technical solution adopted for the present invention to solve the technical problems is：One kind welding gear wheel, with wheel hub, the wheel
Epiplastron, bottom web are welded in hub both sides, and reinforcement is welded to connect between the epiplastron, bottom web, and back-up ring is welded on upper abdomen
Plate, bottom web outer ring, back-up ring are welded to connect with epiplastron, bottom web, and the back-up ring and gear ring are assembled, the back-up ring and gear ring
It is welded to connect, the material that the gear ring is used is 34CrNi3MoA, the material that the wheel hub is used is 42CrMoA, the upper abdomen
The material that plate, bottom web are used is Q345B, and the material that the reinforcement is used is Q345B, the material that the back-up ring is used for
Q345B。
A diameter of 3200mm of the outer rim of the gear ring, the thickness of the wheel hub is 1000mm.
The beneficial effects of the invention are as follows：The present invention is because change the structure of gear so that the allowance of gear, processing
Difficulty is obtained for control well, and by welding procedure, the intensity of gear structure can also reach requirement, effectively control gear
The weight of finished product, reduces the manufacturing cost of gear.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the gear of prior art；
Fig. 2 is the structural representation of gear of the invention；
Wherein, 1, wheel hub, 2, epiplastron, 3, bottom web, 4, reinforcement, 5, gear ring.
Specific embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side
Formula illustrates basic structure of the invention, therefore it only shows the composition relevant with the present invention.
As shown in Fig. 2 a kind of welding gear wheel, with wheel hub 1, epiplastron 2, bottom web is welded in the both sides of the wheel hub 1
3, be welded to connect reinforcement 4 between the epiplastron 2, bottom web 3, back-up ring is welded on epiplastron 2, the outer ring of bottom web 3, back-up ring with
Epiplastron 2, bottom web 3 are welded to connect, and the back-up ring is assembled with gear ring 5, and the back-up ring is welded to connect with gear ring 5, the tooth
The material that circle 5 is used is 34CrNi3MoA, and the material that the wheel hub 1 is used is 42CrMoA, and the epiplastron 2, bottom web 3 are adopted
Material is Q345B, and the material that the reinforcement 4 is used is Q345B, and the material that the back-up ring is used is Q345B.The tooth
A diameter of 3200mm of the outer rim of circle 5, the thickness of the wheel hub 1 is 1000mm.
The present invention is because change the structure of gear so that the allowance of gear, difficulty of processing are obtained for well
Control, by welding procedure, the intensity of gear structure can also reach requirement, effectively control the weight of gear finished product, reduce
The manufacturing cost of gear.
The adoptable concrete technology of the present invention is as follows：
1st, wheel hub and epiplastron, bottom web are welded, welding is incubated after being welded as 300 DEG C of preheating；2nd, postwelding is carried out
Dehydrogenation；3rd, normal temperature welding reinforcement between epiplastron, bottom web；4th, by epiplastron, bottom web outer ring welding back-up ring, welding side
Formula be normal temperature welding, 5, postwelding tempering, it is ensured that the elimination of welding stress；6th, back-up ring external diameter and gear ring major diameter fit tolerance carry out group
Dress, spot welding is taken jail, enters stove and preheated, and welding is incubated after preheating；7th, postwelding tempering, it is ensured that the elimination of welding stress；8th, detect a flaw,
Ensure welding crackle.
With above-mentioned according to desirable embodiment of the invention as enlightenment, by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
