Abstract
The utility model discloses a large scale welding structure carburization quenching gear, mainly consisting of a gear edge(1), a gear hub(2) and an accessory plate(3). The gear edge(1), the gear hub(2) and the accessory plate(3) are integrated into one through welding. The utility model has the advantages of rational design, easy production and high practicality. As the utility model adopts a welding structure, the gear edge can be made of nickel contented good quality low carbon alloy steel material, while the gear hub and the accessory plate can be made of other materials. So that, the utility model also has the advantages of greatly decreasing the production cost, reducing the consumption of the expensive metal and having good economic benefit and social benefit.
Description
The utility model belongs to the gear technique field, and what relate generally to is a kind of large welded structures carburizing and quenching gear.
Existing large-scale its structure of carburizing and quenching hardened face gear mainly contains solid forging or holding type structure.Wherein, the solid forging structural material is the high-quality low-carbon alloy steel, has the defective that whole gear cost is higher, the noble metal use amount is more; And holding type structural manufacturing process more complicated, the processing cost height, and for there being many narrow limitation under the situation of facewidth broad again.Get nickeliferous high-quality low-carbon alloy steel (as 20CrNi2MoA) based on present many hard flank of tooth carburizing and quenching gear material multiselects, whole like this tool gear material and processing cost are just higher, and be just particularly outstanding for this defective of large-scale carburizing and quenching hardened face gear.
The purpose of this utility model promptly produces thus, proposes a kind of large welded structures carburizing and quenching gear.This gear is not only simple in structure, and is practical, and under the prerequisite that guarantees gear transmission function and bearing capacity, can reduce cost significantly, reduces the use amount of noble metal.
For achieving the above object, the utility model is achieved through the following technical solutions: it mainly is made up of wheel rim, wheel hub and disc, and wheel rim, wheel hub and disc are connected as one by welding.
The utility model is reasonable in design, and processing technology is simple, practical.Because it be welded structure, be very suitable for big specification gear, promptly outside diameter greatly, the gear of facewidth broad, be not subjected to the restriction of casehardening furnace.And its wheel rim is to adopt nickeliferous high-quality low-carbon alloy steel (20CrNi2MoA) material, and wheel hub and disc are to adopt other materials (as: Q235-A, ZG270-500) to make, therefore, under the prerequisite that guarantees gear transmission function and bearing capacity, can reduce production costs significantly, reduce the use amount of noble metal, increase economic efficiency.
The utility model has following accompanying drawing:
Accompanying drawing 1 is the utility model structural representation
Accompanying drawing 2 is the utility model structural representation
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
Shown in Fig. 1-2: present embodiment mainly is made up of wheel rim 1, wheel hub 2, disc 3, and wheel rim 1, wheel hub 2 and disc 3 are connected as one by welding.In order to strengthen the intensity of disc 3, be welded with the steel pipe 4 of some 3 of two disc.Between wheel rim 1 and wheel hub 2, be provided with the pin 6 that plays the role of positioning.This embodiment's middle gear external diameter is 2730mm, and the gear width is 580mm, and modulus is 30, and the number of teeth is 89, and gear is the carburizing and quenching hardened face gear.Wheel rim 1 adopts the 20CrNi2MoA material, and wheel hub 2 and disc 3 adopt Q235-A, ZG270-500 material.As calculated, this gear adopts the welding type gear structure can save high-quality low-carbon alloy steel 16632kg than the solid forging structure, saves 24.639 ten thousand yuan of costs.Its economic benefit and social benefit are considerable.
