Abstract

Oil pump gear end face finishing method disclosed by the invention, it is characterized in that, the most hand-held oil pump gear, the end face of oil pump gear contacted gently at the abrasive paper for metallograph 2 of high speed rotating～within 3 seconds, make the surface roughness of this end face up to Ra0.4, then this end face of oil pump gear put essence plain grinding lathe be processed, this end face end making oil pump gear is jumped and is reached 10 microns, within the depth of parallelism reaches 5 microns；Other end according still further to said method processing machine oil pump gear.The present invention improves gear surface precision, improves lubricating oil pump assembly precision, simple to operate, is suitable for producing in enormous quantities, greatly reduces lubricating oil pump noise, makes lubricating oil pump reliability, safety and service life be greatly improved.

Description

Oil pump gear end face finishing method
Technical field
The present invention relates to various high-precision gear face finishing method, throw particularly to oil pump gear end face Light method.
Background technology
Existing gear face is beated, the depth of parallelism ensures bad, because gear is by mill during upper surface grinding machine Roughness the highest, the most jagged, with oilstone polishing can not ensure a collection of gear face burr well Remove clean, therefore grinding backgear end jumped and the depth of parallelism is excessive, cause lubricating oil pump assembly precision the highest, Noise is big, and reliability, safety and service life are the highest.
Summary of the invention
The technical problem to be solved is that the deficiency overcome in existing process technology, and carries For a kind of oil pump gear end face finishing method, the method can improve the roughness of end face, makes gear put Time on surface grinding machine good with contacting of workbench, it is ensured that plain grinding processing rear end face beat and the depth of parallelism Precision improves, so that lubricating oil pump assembly precision improves, noise declines substantially, improve its reliability, Safety and service life.
The technical problem to be solved can be achieved through the following technical solutions:
Oil pump gear end face finishing method, it is characterised in that the most hand-held oil pump gear, by machine The end face of oil pump gear contacts gently at the abrasive paper for metallograph 2 of high speed rotating～makes this end face in 3 seconds Surface roughness up to Ra0.4, then this end face of oil pump gear put essence plain grinding lathe carry out Processing, makes this end face end of oil pump gear jump and reaches 10 microns, within the depth of parallelism reaches 5 microns；Again The other end of processing machine oil pump gear according to the method described above.
The present invention compared with prior art has a following features:
The present invention improves gear surface precision, improves lubricating oil pump assembly precision, simple to operate, suitable It is suitable for production in enormous quantities, greatly reduces lubricating oil pump noise, make lubricating oil pump reliability, safety and make It is greatly improved with the life-span.
Detailed description of the invention
Oil pump gear end face finishing method, its most hand-held oil pump gear, by oil pump gear End face contacts gently at the abrasive paper for metallograph 2 of high speed rotating～within 3 seconds, makes the surface roughness of this end face Up to Ra0.4, then this end face of oil pump gear put essence plain grinding lathe be processed, make machine This end face end of oil pump gear is jumped and is reached 10 microns, within the depth of parallelism reaches 5 microns；According still further to above-mentioned side The other end of method processing machine oil pump gear.
