Abstract
The utility model relates to the field of mechanical processing, in particular to an intersecting-axis variable-gear-thickness right rotating bevel gear applicable to generating cutting. The utility model aims at providing the intersecting-axis variable-gear-thickness right rotating bevel gear applicable to generating cutting for improving the finished product rate and prolonging the service life of products. The tooth of the variable-gear-thickness right rotating bevel gear is in a drum shape, in addition, the two ends of the tooth are in a reverse slop shape, and the gear thickness of the right rotating bevel gear is gradually reduced from the large end to the small end. The intersecting-axis variable-gear-thickness right rotating bevel gear utilizes computer software for researching and modifying important parameters of gear tooth number, modulus number, position change factors and the like so that the phenomena of root cutting, tooth top sharpening and the like are prevented, then, a gear hobbing machine is reformed according to the generating cutting processing principle, a special clamp and a generating mechanism are designed, the intersecting-axis variable-gear-thickness right rotating bevel gear with the conical angle Delta being only 1.09 degrees is processed, and high industrial practical values are realized.
Description
Technical field
The utility model relates to field of machining, is specifically related to a kind of concurrent aces that is applicable to generating cutting and becomes transverse tooth thickness dextrorotation helical gear.
Background technique
Became transverse tooth thickness dextrorotation helical gear for concurrent aces in the past, because can't become processing by model, can only carry out correction of the flank shape processing at plain-milling machine, owing to there being the principle mistake, therefore the various faults of involute variable tooth thickness gear often occurs, such as undercut, topping etc., the utility model is reequiped gear hobbing machine, designed Specific Clamps, developed concurrent aces and become transverse tooth thickness dextrorotation helical gear.Owing to avoided the principle mistake, so service life of gear improving obviously.
The model utility content
For above-mentioned situation, the purpose of this utility model provides a kind of concurrent aces that is applicable to generating cutting and becomes transverse tooth thickness dextrorotation helical gear, to improve yield rate and the life-span of product.
In order to reach the foregoing invention purpose, the technical solution of the utility model is: the concurrent aces that is applicable to generating cutting becomes the helical gear tooth of transverse tooth thickness dextrorotation and is cydariform, and the two ends of described tooth are the adverse slope shape, and the transverse tooth thickness of described dextrorotation helical gear from large end to small end diminishes gradually.
Preferably, the helical gear cone angle of described dextrorotation is 1.09 °.
Owing to having adopted technique scheme, the utility model to utilize computer software to grope, revise the important parameters such as the number of teeth of gear, modulus, modification coefficient, to prevent the phenomenons such as undercut, topping.Then become process principle according to model, the repacking gear hobbing machine is designed special fixture and is become mechanism with model, and processing a cone angle δ only is the concurrent aces change transverse tooth thickness dextrorotation helical gear of 1.09 degree, has industrial practice and is worth.The utility model can realize reliably easily on gear hobbing machine that the minimum concurrent aces of cone angle δ becomes the helical gear model of transverse tooth thickness dextrorotation and becomes processing, has increased the helical gear model of a kind of novel change transverse tooth thickness dextrorotation and has become processing method.
Description of drawings
Fig. 1 is the schematic diagram of the utility model dextrorotation helical gear contrate tooth profile;
Fig. 2 is the helical gear plan view of the utility model dextrorotation;
Fig. 3 is the schematic diagram of the utility model dextrorotation helical gear crowned teeth;
Fig. 4 is the adverse slope shape schematic diagram at the utility model dextrorotation helical gear two ends.
Embodiment
Below in conjunction with drawings and Examples embodiment of the present utility model is further described, but should limit protection domain of the present utility model with this.
Fig. 1 becomes the helical gear contrate tooth profile of transverse tooth thickness dextrorotation, as seen its profile of tooth left-right asymmetry.Fig. 2 becomes transverse tooth thickness to revolve helical gear plan view, as seen diminishes gradually from large end 1 to small end 2 transverse tooth thickness.Along facewidth direction even contact, prevent unbalance loading in order to be two as far as possible when becoming Tooth Thickness Helical Gear and intermeshing, we make crowned teeth with the gear teeth, and as shown in Figure 3, wherein 3 is the cydariform amount.For guaranteeing the stressed even of the gear teeth, we have designed the adverse slope shape at two ends in addition, and as shown in Figure 4, wherein 4 is adverse slope.
The helical gear course of working of the utility model dextrorotation is as follows:
1, the model of design specialized variable tooth thickness gear becomes mechanism and anchor clamps;
2, then reequip gear hobbing machine;
3, design compilation gear processing;
4, design customization dextrorotation becomes the dedicated asymmetric tooth-profile of gear hobboing cutter of Tooth Thickness Helical Gear;
5, carry out at last gear hobbing processing;
6, the dimensional accuracy of check gear product.
The above is better embodiment of the present utility model only, is not to limit practical range of the present utility model.Have in the technical field under any and usually know the knowledgeable, within not breaking away from spirit and scope of the present utility model, when being used for a variety of modifications and variations, therefore protection domain of the present utility model should be as the criterion with claims institute confining spectrum.
Claims (2)
1. a concurrent aces that is applicable to generating cutting becomes transverse tooth thickness dextrorotation helical gear, and it is characterized in that: the helical gear tooth of described dextrorotation is cydariform, and the two ends of described tooth are the adverse slope shape, and the transverse tooth thickness of described dextrorotation helical gear from large end to small end diminishes gradually.
2. the concurrent aces that is applicable to generating cutting as claimed in claim 1 becomes transverse tooth thickness dextrorotation helical gear, and it is characterized in that: the helical gear cone angle of described dextrorotation is 1.09 °.
