Abstract
The invention discloses an index plate machining high-precision gear tooth grinding technology. The index plate machining high-precision gear tooth grinding technology comprises the following steps that a large plane grinding wheel gear grinding machine is used for machining a gear blank with the number z of teeth of a ground gear two times of the number Z of working grooves of an adopted index plate; an odd number of same-name tooth faces of the gear blank are subjected to fine machining to serve as standard tooth faces, an even number of same-name teeth of the gear blank are subjected to semifinishing, pitch deviation of all teeth of the left tooth face of the gear blank is measured, and the working allowance of an even number of teeth of the left tooth face is determined according to the average deviation of an algebraic sum of the single pitch deviation of an even number of tooth faces and the standard tooth faces; an even number of teeth of the left tooth face continue to be subjected to fine machining until the working allowance of the tooth face to be machined is smaller than a set machining threshold value; an even number of teeth of the right tooth face continue to be subjected to fine machining until the working allowance of the machined tooth face is smaller than a set machining threshold value. The index plate machining high-precision gear tooth grinding technology has the advantages that the number of machining steps is small, the grinding allowance is small, and the product precision is high.
Description
Technical field
The present invention relates to field of machining, especially index dial processes high-accuracy gear grinding technique.
Background technology
Gear is in numerous areas extensive uses such as equipment manufacturing, automobile, boats and ships precision instruments, traditional gear-grinding process limits the kind of the index dial processing tooth base number of teeth, for expanding the range of work of index dial, existing large plane grinding-wheel gear grinding machine all adopts index dial to be indexing system, but due to problems such as manufacturing costs, be not used widely in actual production.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of index dial and process high-accuracy gear grinding technique, procedure of processing is few, and grinding allowance is little, and Product Precision is high.
In order to realize foregoing invention object, the invention provides following technical scheme:
A kind of index dial processes high-accuracy gear grinding technique, comprises the steps, is doubled the tooth base of index dial work nest number Z used with large plane grinding-wheel gear grinding machine processing by roll flute tooth number z; First fine finishining goes out one group of odd number flank of tooth of the same name of tooth base as the benchmark flank of tooth, then semifinishing tooth base even number tooth of the same name, measure the circular pitch deviation of the left flank of tooth of tooth base all teeth, determine the allowance of left flank of tooth even number tooth according to the mean difference of the even number flank of tooth and the benchmark flank of tooth single circular pitch deviation algebraical sum;
Continue the even number tooth of the left flank of tooth of fine finishining, until the allowance of the flank of tooth to be processed is less than the processing threshold value of setting;
Continue fine finishining right flank of tooth even number tooth, until the allowance of the processing flank of tooth is less than the processing threshold value of setting.
Further, gear grinding machines are large plane grinding-wheel gear grinding machine.
Compared with prior art, the present invention has the following advantages:
Procedure of processing of the present invention is few, and grinding allowance is little, and the amplitude change of single circular pitch deviation is no more than 0.49 μm, thus ensure that the single tooth pitch precision of tooth base is repeatedly processed in the grouping of application index dial.(2) many in positive and negative alternately variation tendency owing to adopting this process to obtain the single circular pitch deviation of tooth base, the tooth pitch that therefore can not increase tooth base during fine finishining adds up total deviation (3) and adopts this process, and the integral multiple that range of numbers of teeth index dial can being processed tooth base increases to index dial work nest number by the work nest number of index dial significantly increases the scope that index dial processes the tooth base number of teeth.
Detailed description of the invention
Describe the present invention below, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of index dial processes high-accuracy gear grinding technique, comprises the steps, is doubled the tooth base of index dial work nest number Z used with large plane grinding-wheel gear grinding machine processing by roll flute tooth number z; Gear grinding machines are large plane grinding-wheel gear grinding machine.First fine finishining goes out one group of odd number flank of tooth of the same name of tooth base as the benchmark flank of tooth, then semifinishing tooth base even number tooth of the same name, measure the circular pitch deviation of the left flank of tooth of tooth base all teeth, determine the allowance of left flank of tooth even number tooth according to the mean difference of the even number flank of tooth and the benchmark flank of tooth single circular pitch deviation algebraical sum;
Continue the even number tooth of the left flank of tooth of fine finishining, until the allowance of the flank of tooth to be processed is less than the processing threshold value of setting;
Continue fine finishining right flank of tooth even number tooth, until the allowance of the processing flank of tooth is less than the processing threshold value of setting.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
