Abstract
The utility model discloses a holding assembling type gear of a hard tooth surface. The utility model comprises a flange (1), a hub (2) and a bolt (3), the flange(1) is connected with the hub(2) fixedly by the bolt holding assembling. The utility model is proper in design and simple in structure, because of the holding assembling type structure, the flange can choose the material of 20 CrNi2MoA to be made, and the hub can choose the material of ZG 270-500 to be made. In this way, before the function of the hard tooth surface gear is ensured, the production cost is reduced largely, the use amount of precious mental is reduced to enhance economic benefit.
Description
The utility model belongs to the gear technique field, and what relate generally to is the box-like gear of a kind of hard flank of tooth.
Existing hardened face gear structure is the solid forging structure substantially.The material that uses mostly is the noble metal class, and as the high-quality low-carbon alloy steel, nickeliferous high-quality low-carbon alloy steel etc. so just make the cost of production height of whole gear, and the noble metal use amount is big.Especially more outstanding for big specification hardened face gear
The purpose of this utility model promptly produces thus, proposes a kind of hard flank of tooth holding type gear.This holding type gear can reduce production costs under the prerequisite that guarantees hard flank of tooth tooth function greatly, reduces the use amount of noble metal.
For achieving the above object, the utility model is achieved through the following technical solutions: it is made up of wheel rim, wheel hub, and wheel rim and wheel hub are fixedly connected closing by crossing bolt.
The utility model is reasonable in design, and is simple in structure.Because it is the holding type structure, wheel rim can be selected high-quality low-carbon alloy steel material for use, and wheel hub can be selected the ZG270-500 material for use.Like this, under the prerequisite that guarantees the hardened face gear function, can reduce production costs greatly, reduce the use amount of precious metal, and then increase economic efficiency.
The utility model accompanying drawing is a structural representation
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in the figure, present embodiment is the carburizing and quenching hardened face gear.Adopt the holding type gear structure.Gear is made up of wheel rim 1, wheel hub 2 and bolt 3, and wheel rim 1 adopts the 20CrNi2MoA material, which is provided with the Bolt Connection hole; Wheel hub 2 adopts the ZG270-500 material, also is provided with the Bolt Connection hole on it.Wheel rim 1 is fixedly connected closing by bolt 3 with wheel hub 2.This embodiment's middle gear directly is 1402.65mm, and the gear width is 350mm, and modulus is 14, and the number of teeth is 95.Through relatively, adopt the holding type gear structure than the solid forging structure, can save high-quality low-carbon alloy steel 2199kg, save 3.6102 ten thousand yuan of costs.
Claims (1)
1, a kind of hard flank of tooth holding type gear, it is characterized in that: it is made up of wheel rim (1), wheel hub (2) and bolt (3), and wheel rim (1) is fixedly connected closing by bolt (3) with wheel hub (2).
