Abstract
The invention discloses a method for processing a keyway through a helical gear. The method comprises the steps of mounting a welding steel plate on the non-matching surface of a helical gear part; milling a reference plane through a planer type milling machine; and aligning the axis of the helical gear part according to the reference plane, so as to process the keyway. The method has relatively good universality, the location accuracy of the keyway position is high, the processing and manufacturing process is simple, the welding steel plate loss is less and can be reused, and the production cost is reduced while the production efficiency is improved.
Description
Technical field
The present invention relates to field of machining, especially one for the processing method of helical gear to keyway.
Background technology
Gear wheel rim has tooth can engage the mechanical organ transmitting motion and power continuously.In machine-building, gear is a kind of high-precision product.The form of gear tooth all has required precision, particularly helical gear, and bevel wheel machining keyway has required precision to tooth.Generally there are two kinds of processing methods: one is adopt lathe groove, afterwards in the processing method adopting Linear cut, according to center line that lathe is carved to process keyway; Another kind method is the frock of design specialized, and this method is relatively high relative to first method precision, but frock making process is complicated, cost is high, and the selectivity of this frock is stronger, poor universality.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, and provide a kind of versatility good, high to tooth processing progress, production efficiency is high, low a kind of for the processing method of helical gear to keyway of production cost.
The technical solution adopted for the present invention to solve the technical problems is: a kind of for the processing method of helical gear to keyway, is applicable to accurately locate inner hole key slot position according to helical teeth feature, comprises the steps:
1) the non-mating surface of the helical gear part after fine finishining welds a block welding steel plate;
2) excellent to difference symmetrical insertion pitch circle in the both sides teeth groove of tooth needed for processed keyway, the axis of two pitch circle rods is connected to form a plane, use planer-type milling machine to mill out datum plane on welding steel, described datum plane is parallel with the plane that the axis of above-mentioned pitch circle rod is connected to form;
3) use dial gauge to carry out centering by datum plane, find out the axial location of helical gear part, and linear cutter keyway is carried out to helical gear part;
4) take off welding steel and remove the high point fixed welding steel and cause.
In order to better find the center of circle of the non-mating surface of helical gear part accurately, step 3) in touch by dial gauge the center of circle that datum plane finds the non-mating surface of helical gear part accurately.
Further, step 4) in take off the method for welding steel for knocking.
Accordingly, step 4) in remove high point method remove for using sander grinding.
Step 4) in remove high point methods and also can be helical gear part end face made allowance, knock and remove after welding steel, finish turning helical gear part end face removes high point.
The invention has the beneficial effects as follows: provided by the invention a kind of for the processing method of helical gear to keyway, by at the non-mating surface welding steel of helical gear part, and on welding steel, mill out datum plane by gantry mill, there is good versatility, and keyway position setting accuracy is high, processing and making process is simple, and welding steel loss is less and can utilize by secondary, while enhancing productivity, reduce production cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. helical gear part 2. welding steel 3. teeth groove 4. pitch circle rod 5. datum planes in figure
Detailed description of the invention
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1 a kind of for the processing method of helical gear to keyway, is applicable to accurately locate inner hole key slot position according to helical teeth feature, comprises the steps:
1) the non-mating surface of the helical gear part 1 after fine finishining welds a block welding steel plate 2.Described welding steel 2 is according to having certain thickness and length, and installation site is without strict required precision.
2) inserting pitch circle rod 4 to respectively symmetrical in the both sides teeth groove 3 of tooth needed for processed keyway, the axis of two pitch circle rods 4 is connected to form a plane, use planer-type milling machine to mill out datum plane 5 on welding steel 2, described datum plane 5 is parallel with the plane that the axis of above-mentioned pitch circle rod 4 is connected to form.
3) use dial gauge to carry out centering by datum plane 5, find out the axial location of helical gear part 1, and linear cutter keyway is carried out to helical gear part 1.
4) knock and take off welding steel 2 and remove the high point that fixing welding steel 2 causes.Now, the method removing high point is removed for using sander grinding; Also can be helical gear part 1 end face made allowance, knock after removing welding steel 2, finish turning helical gear part 1 end face removes high point.
Adopt above-mentioned processing method, adding man-hour to keyway, the connection datum level of two pitch circle rod 4 axial lines leads to gantry mill to be transferred on welding steel 2, then by dial gauge centering Gear axis, conveniently can carry out linear cutter.Compared to lathe groove and design specialized frock, by teeth groove 3 interpolation pitch circle rod 4 can be convenient to helical gear internal control keyway to tooth requirement, there is good versatility.Be transferred on welding steel 2 by datum plane 5 simultaneously, avoid multiple bearing, keyway position setting accuracy is high, and processing and making process is simple, cheap, used welding steel 2 also can use by secondary, and loss is less, improve production efficiency high, reduce production cost.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
