Description
Technical field
It is especially a kind of for processing method of the helical gear to keyway the present invention relates to field of machining.
Background technology
Gear is that with teeth can continuously engage transmits motion and the mechanical organ of power on wheel rim.In machine-building, gear
It is a kind of high-precision product.The form of gear tooth has required precision, particularly helical gear, and bevel wheel machining keyway has precision will to tooth
Ask.Typically there are two kinds of processing methods：One is to use lathe groove, afterwards in the processing method using wire cutting, according to lathe institute
Center line is carved to process keyway；Another method is the frock of design specialized, and this method is relative relative to first method precision
It is higher, but frock making process is complicated, cost high, and the selectivity of this frock is stronger, poor universality.
The content of the invention
The technical problem to be solved in the present invention is：Overcome deficiency in the prior art good there is provided a kind of versatility, to tooth plus
Work progress is high, and production efficiency is high, a kind of low processing method for being used for helical gear to keyway of production cost.
The technical solution adopted for the present invention to solve the technical problems is：A kind of processing side for being used for helical gear to keyway
Method, it is adaptable to inner hole key slot position is accurately positioned according to the feature of helical gear part, comprised the following steps：
1) the non-mating surface of the helical gear part after finishing welds a block welding steel plate；
2) pitch circle rod, the axle of two pitch circle rods are respectively symmetrically inserted in the both sides teeth groove needed for processed keyway to tooth
Line is connected to form a plane, and datum plane, the datum plane and above-mentioned pitch circle are milled out on welding steel using planer-type milling machine
It is parallel that the axis of rod connects the plane to be formed；
3) centering is carried out by datum plane using dial gauge, finds out the axial location of helical gear part, and to helical gear
Part carries out linear cutter keyway；
4) remove welding steel and remove high point caused by fixed welding steel.
In order to preferably find the center of circle of the non-mating surface of helical gear part, step 3 accurately) in datum plane is touched by dial gauge
Find the center of circle of the non-mating surface of helical gear part accurately.
Further, step 4) in the method for welding steel is removed to tap.
Accordingly, step 4) in remove high point method be using sander grind remove.
Step 4) in remove high point methods and be alternatively helical gear part end face made allowance, tap and remove after welding steel, essence
Car helical gear part end face removes high point.
The beneficial effects of the invention are as follows：The present invention provide it is a kind of for helical gear to the processing method of keyway, by
The non-mating surface welding steel of helical gear part, and datum plane is milled out on welding steel by gantry mill, with preferably logical
With property, and keyway position setting accuracy is high, and processing and making process is simple, and welding steel loss is less and secondary can utilize,
Production cost is reduced while improving production efficiency.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
The datum plane of 1. helical gear part, 2. welding steel, 3. teeth groove, 4. pitch circle rod 5. in figure
Embodiment
Presently in connection with accompanying drawing and preferred embodiment, the present invention is further illustrated.These accompanying drawings are simplified signal
Figure, only illustrates the basic structure of the present invention in a schematic way, therefore it only shows the composition relevant with the present invention.
As shown in Figure 1 is a kind of for processing method of the helical gear to keyway, it is adaptable to according to the feature of helical gear part
Inner hole key slot position is accurately positioned, is comprised the following steps：
1) the non-mating surface of the helical gear part 1 after finishing welds a block welding steel plate 2.The evidence of welding steel 2
There are certain thickness and length, installation site is without strict required precision.
2) pitch circle rod 4, two pitch circle rods 4 are respectively symmetrically inserted in the both sides teeth groove 3 needed for processed keyway to tooth
Axis connect to form a plane, mill out datum plane 5 on welding steel 2 using planer-type milling machine, the datum plane 5 with it is upper
Stating the axis of pitch circle rod 4, to connect the plane to be formed parallel.
3) centering is carried out by datum plane 5 using dial gauge, finds out the axial location of helical gear part 1, and to helical teeth
Take turns part 1 and carry out linear cutter keyway.
4) percussion removes welding steel 2 and removes high point caused by fixed welding steel 2.Now, the method for removing high point
Removed to be ground using sander；Or the end face made allowance of helical gear part 1, tap and remove after welding steel 2, smart car helical teeth
Take turns the end face of part 1 and remove high point.
Using above-mentioned processing method, when being processed to keyway, the connection reference plane of two axial lines of pitch circle rod 4 leads to gantry
Milling is transferred on welding steel 2, then can pass through dial gauge centering Gear axis, you can convenient to carry out linear cutter.Compare
In lathe groove and design specialized frock, by the interpolation pitch circle rod 4 of teeth groove 3 can be easy to helical gear internal control keyway to tooth requirement,
With preferable versatility.Datum plane 5 is transferred on welding steel 2 simultaneously, it is to avoid multiple bearing, keyway position positioning accurate
Exactness is high, and processing and making process is simple, cheap, and used welding steel 2 secondary can also be used, and loss is less, carries
High production efficiency is high, reduces production cost.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to the present invention
The equivalent change or modification that Spirit Essence is made, should all cover within the scope of the present invention.
