Abstract
The invention discloses a shape correction method for reducing noise or abnormal sound of gears. The shape correction method includes that (A), edge correction start points of the driven gears are determined, to be more specific, coincidence degrees of the gears are 1.0-2.0, two pairs of teeth mesh with each other before points b are released from meshing in the instant that single teeth of the driving gears and the driven gears are about to mesh with one another, the shapes of the driven gears are corrected at the moment, the edge correction start points are meshing points a, and the edge correction ranges range from the meshing points a to tooth crest regions of the driven gears; (B), edge correction start points of the driving gears are determined, to be more specific, points c are meshing limit points of every two corresponding teeth in the instant that the two teeth of each driving gear and the corresponding driven gear are about to mesh with each other, areas from the points c to tooth crest regions of the driving gears participate in meshing of two pairs of teeth, the edge correction start points of the driving gears are the points c, and the edge correction ranges range from the points c to the tooth crest regions of the driving gears. The shape correction method for reducing the noise or the abnormal sound of the gears has the advantages that the edge correction points and edge correction radiuses are accurately determined, the shapes of the gears can be corrected, and accordingly the noise and the abnormal sound can be eliminated when the two pairs of teeth or more than two pairs of teeth mesh with each other.
Description
Technical field
The present invention relates to gear technique field, and in particular to a kind of design of gears method of reduction gear transmission noise.
Background technology
Involute cylindrical gear can effectively transmit motion and load, be widely used in all kinds of machine drivings, gear
The correct condition of engagement is that coupling gear base pitch is equal, requires that registration, more than 1.0, works as coincidence to ensure that the gear teeth can be engaged continuously
Spend is 1.0<ε<It is that a pair of tooth engagements are engaged alternately with two pairs of teeth, when registration is 2.0 on actual line of action when 2.0
<ε<It is that two pairs of tooth engagements are engaged alternately with three pairs of teeth when 3.0, when a pair of teeth are engaged, base pitch deviation does not influence engagement property
Can, when two pairs or more tooth simultaneously engage when, as base pitch deviation be zero theoretically in the absence of interference, in fact, plus
The gear teeth certainly exist base pitch deviation after work（Positive or negative value）And the base pitch change that the lower gear tooth deformation of load effect is produced, therefore tooth
The time that face enters engagement just has early or late, and the relatively early gear teeth into engagement are then dry in interference and squeezed state-i.e. engagement
Relate to, when gear operation especially runs at high speed, this interference can produce larger noise and abnormal sound, solution is needed for this, and this is asked
Topic.
The content of the invention
In order to solve the problems, such as during gear operation produce noise and abnormal sound, the invention provides one kind reduce gear noise or
The correction method of abnormal sound.
The technical scheme that is used to achieve the above object of the present invention is：A kind of correction of the flank shape side for reducing gear noise or abnormal sound
Method：
（A）, the tip relief starting point of driven gear 2 determination, the registration of gear 1 and gear 2 is 1.0-2.0, driving gear 1 with from
Moving gear 2 will enter the moment of monodentate engagement, be two pairs of tooth engagements before b point drop out of gears, now to the correction of the flank shape of driven gear 2, tip relief
Starting point is meshing point a, and tip relief scope is meshing point a to the tooth top region of driven gear 2；
（B）, the tip relief starting point of driving gear 1 determination, driving gear 1 will engage moment with driven gear 2 into two teeth, c
Point is the limit point of two teeth engagement, and c points to driving gear tooth top region take part in two pairs of tooth engagements, and the tip relief of driving gear 1 rises
Initial point is c points, and tip relief scope is c points to the tooth top region of driving gear.
The correction method for reducing gear noise or abnormal sound of the invention, by accurately determining tip relief point and tip relief radius pair
Gear carries out correction of the flank shape, can realize being abated the noise and abnormal sound when two pairs and more than two pairs teeth engagements.
Brief description of the drawings
Fig. 1 is that driving gear 1 will enter the moment schematic diagram that monodentate is engaged with driven gear 2.
Fig. 2 is that driving gear of the present invention 1 will engage moment schematic diagram with driven gear 2 into two teeth.
Fig. 3 is tooth sectional side view.
In figure：1st, driving gear, 2, driven gear.
Specific embodiment
The correction method for reducing gear noise or abnormal sound of the invention, referring to Fig. 1 and Fig. 2, wherein：L-theoretical line of action
Length；L1-length；L2-length；Pb-base pitch length；The tip circle radius of Ra1-driving gear 1；The tip circle of Ra2-driven gear 2
Radius；The base radius of Rb1-driving gear 1；The base radius of Rb2-driven gear 2.
Fig. 1 show driving gear 1 will enter the moment that monodentate is engaged with driven gear 2, be two pairs of teeth before b point drop out of gears
Engagement, it is assumed that the registration of gear 1 and gear 2 is 1.0-2.0, now to the correction of the flank shape of driven gear 2, correction of the flank shape starting point is to nibble
To the tooth top region of driven gear 2, dx1 is the involute tip relief of driving gear 1 starting spot diameter to chalaza a.Fig. 3 is shown in correction of the flank shape, wherein：Ø
Dnf max are involute starting spot diameter maximum；Dx is profile modification starting spot diameter, and dna is that involute terminating point is straight
Footpath；K is profile modification amount；E is the facewidth.
Equally, Fig. 2 will be engaged moment for driving gear 1 with driven gear 2 into two teeth, and c points are the pole of two teeth engagement
Point of accumulation, c points to driving gear tooth top region take part in the engagement of the two pairs of teeth, thus driving gear correction of the flank shape point from c points to driving tooth
The tooth top region of wheel, dx2 is the involute tip relief of driven gear 2 starting spot diameter, and Fig. 3 is shown in correction of the flank shape.
The processing of profile modifying gear as shown in Figure 3, at present, high class gear based on shaving nitridation and carburizing and quenching, for
Nitridation gear, can realize the processing of the form of gear tooth, for carburizing and quenching gear, using Buddha's warrior attendant by reconditioning gear shaver knife-edge
Stone roller grinding wheel realizes the processing of design tooth profile.
The present invention is described by embodiment, and those skilled in the art know, is not departing from spirit of the invention
In the case of scope, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, in religion of the invention
Lead down, these features and embodiment can be modified to adapt to particular situation and material without departing from essence of the invention
