Description
Technical field
Present invention relates particularly to the design methods of a kind of planetary gear on end-face grinding machine and the planetary gear endoporus.
Background technology
Planetary gear is the main tooling of cylindrical roller end-face grinding machine.In grinder, planetary gear had not only had revolution but also had had
Rotation, workpiece does reciprocal planetary motion in planetary gear by inner ring drive, and has upper and lower abrasive disk spin finishing.It is ground in plane
In mill, it is desirable that workpiece motion s track equably spreads entire lap tool surface, in favor of lap tool uniform wear.Lapping using star lapping machine processing
Grinding track is complicated, and inside and outside processing situation is consistent, to allow workpiece end face to obtain good vertical difference and parallel error.
End-face grinding machine divides different size, and the end-face grinding machine range of work for being commonly used to cylindrical roller processing at present is φ
3~φ 50, the roller precision after processing：End face run-out, parallel error are less than 0.002mm, surface roughness is less than Ra0.125.Add
Work efficiency rate：Often the process time of disk roller be 5~10 minutes, often the processing quantity of disk roller according to the diameter of roller 6
Between~1300.Machining accuracy, efficiency are higher.End-face grinding machine is generally used for the whole mill processing of cylindrical roller end face.
The existing design method of planetary gear is that 4~5 macropores are opened on planetary gear, and roller is enclosed along the internal diameter row one in hole,
It, be in centre plus a spacer to prevent roller from shaking and rollover.
The material of planetary gear is generally modulated using No. 45 steel, and spacer uses GCr15.Circular needs to be related to three
Formula, complex steps and trouble.When calculating spacer outer diameter, radial clearance stays 0.3~0.5mm.This comparison for calculation methods is multiple
It is miscellaneous.Particularly with the smaller roller of roller diameter, diameter 7mm hereinafter, in calculating process total backlash δ and roller diameter direction
Expose when value is careless slightly or the tolerance value of process mesoporous is close to the limit of abrasive disc size, just will produce roller
It falls or the phenomenon that last roller can not load.If generating roller phenomenon in process, abrasive disc crash can be caused,
It is breakneck.
Original planetary gear both ends of the surface are designed as flat.The sand that original domestic end-face grinding machine such as MB43100, MB4363 are used
Wheel disc is elastic grinding wheel, and since grinding wheel material and granularity are thicker, planetary gear does not stick on abrasive disc.And it is used at present high-precision
Degree grinder abrasive disc material is CBN grinding wheels, and granularity is thinner.Due to the difference of cooling system, planetary gear often adheres to sand
On wheel disc, when adhering to lower grinding wheel disk, planetary gear can take any more；If adhering to abrasive disc, it is easy to fall down and injures abrasive disc by a crashing object.Problem above
So far it is not solved effectively.
Invention content
The object of the present invention is to provide the design sides of a kind of planetary gear on end-face grinding machine and the planetary gear endoporus
Method, calculates that complicated, structure design is unreasonable to solve the planetary gear on existing end-face grinding machine there are size, and it is de- that roller easily occurs
