Technical field
The invention belongs to face gear numerical control gear milling, this field of roll flute processing in the gear manufacturing approach.
Background technology
The face gear drive be meant be meshed roller gear intersect the implementation space with bevel gear or alternating axis between transmission.Compare with bevel gear, the face gear drive has that registration is big, bearing capacity is strong, stability is strong, vibration is little, advantage such as little takes up space.Along with the development of Aero-Space cause, the face gear drive has obtained extensive use in the power set of aircraft, occupies very consequence.
The face gear working method is one of main task of face gear research, and Chinese scholars has been done a lot of researchs to it in recent years, but the present processing method of opposite gear at home is Gear Shaping mostly; The face accuracy of gear that processes is lower; Bearing capacity is relatively poor, makes the application of face gear can only rest on the occasion of low speed, underloading, can not satisfy the transmission requirement of aviation apparatus; In order to improve the comprehensive transmission performance of face gear, the high accuracy manufacturing of necessary realization face gear.The transmission performance of face gear is further improved; Generally need the opposite gear to heat-treat; And heat treatment will produce the heat expansion distortion to tooth surface of face gear, and the precision of influence surface gear and transmission performance are because tooth face hardness is very high after the heat treatment; Adopt general processing method to be difficult for processing, must study the roll flute processing method could solve.
For the processing of face gear mill teeth and roll flute, domestic still do not have ready-made lathe and can realize.In U.S. Patent number US6390894 (B1), designed a kind of gear grinding lathe, this lathe is designed to vertical direction with face gear blank erecting bed; Reduced the rigidity of lathe; Reduced machining accuracy, this machine tool structure is complicated simultaneously, and the machine tool motion axle has ten more than; Increase the difficulty of numerical control control, also increased cost.On the whole, the research of opposite gear grinding processing has in recent years obtained certain progress, but the grinding machine bed complex structure that is designed, machining accuracy and production efficiency can not satisfy market demand fully.
This patent has been invented a kind of disk wheel cutter that utilizes on existing roller gear gear form-grinding machine bed basis; Through being installed, an additional numerical control rotating platform realizes the processing method of face gear high accuracy roll flute; This method is utilized existing roller gear gear form-grinding machine bed and disk wheel; Realization is created to the high accuracy of tooth surface of face gear, reaches the effect of face gear high-precision processing, need not the special-purpose roll flute machining tool that otherwise designed is made the face gear; Greatly reduce production cost, shortened the construction cycle.
Summary of the invention
The technical problem that this patent solves is: defectives such as, transmission performance difference low to Gear Processing precision above the market; Invented a kind of disk wheel cutter that utilizes on existing roller gear gear form-grinding machine bed basis, realized the processing method of face gear high accuracy roll flute through an additional numerical control rotating platform is installed.This method can be carried out roll flute processing to the face gear after the heat treatment, realizes the high-precision processing of opposite gear, improves the transmission performance of face gear.
The face gear grinding processing method of this patent invention is characterized in that: a vertical additional numerical control rotating platform 4, the index dial rotation along continuous straight runs of numerical control rotating platform 4 installed on the lathe index table; Numerical control rotating platform 4 is furnished with motor and driver and is connected to the digital control system of lathe, is rotated around lathe Y axle by digital control system control, and face gear 1 is installed on the additional numerical control rotating platform 4; Disk wheel 2 is installed on the machine tool chief axis, and in process, face gear 1 rotates around the B1 rotating shaft with additional number control turntable 4; Simultaneously face gear 1 is with lathe A rotation axis oscillating, and disk wheel 2 rotates at a high speed around self axis with main shaft, and disk wheel 2 radially comes and goes feed motion at the face gear simultaneously; After processing a complete teeth groove; The face gear carries out dividing movement, to process next teeth groove, up to processing whole gear.
Because the gear teeth of face gear are in the end face of gear; Therefore to realize the roll flute processing of face gear; One additional numerical control rotating platform 4 must vertically be installed on former lathe circular dividing table, make lathe realize the calibration function of along continuous straight runs, keep very high kinematic accuracy in order to make improved lathe; The additional numerical control rotating platform of installing 4 is furnished with motor and driver and is connected to the digital control system of lathe, and it realizes accurately motion by digital control system control.
Engagement rule by face gear 1, disk wheel 2 and spur gear 3 can know that the axial cross section profile of the disk wheel 2 that is utilized should be identical with the axial profile of spur gear 3.In order to guarantee face gear 1 and disk wheel 2 accurate generates, face gear 1 rotates and is constant with the rotating ratio of additional number control turntable A rotation axis oscillating around self axis with lathe B1 rotating shaft in process, and
N wherein
cWith N
fBe respectively the number of teeth of spur gear 3 and face gear 1.
In process; Small angle of face gear 1 every swing, disk wheel 2 radially comes and goes feeding once the face gear, so repeatedly up to processing a complete teeth groove; After processing a complete teeth groove; The face gear carries out dividing movement, to process next teeth groove, up to processing whole gear.
Said spur gear 3 is virtual, and in the process of reality, spur gear 3 is non-existent, in the drawings it is drawn just for process principle better is described.Simultaneously all need carry out heat treatment earlier in processing as last, to improve the combination property of material at the flank of tooth of real machined surface gear 1.
