The tooth surface equation of described enveloping worm 16 is

Wherein, A=-cos α_dCos θ, B=-cos α_dsinβsinθ±sin α_dCos β, C=-cos α_dcosβsinθ±sinα_dSin β, D=r_dcosθ-a₀, E=r_dsinβsinθ±0.5S_aCos β, F=- r_dcosβsinθ±0.5S_acosβ,n_x=sin α_dcosθ,n_y=sin α sin θ sin β+cos α_dCos β, n_z=-sin α_dsinθcos β+cosα_dSin β, α_dFor processing the emery wheel profile angle of enveloping worm 16, r_dFor processing the grinding wheel radius of enveloping worm 16, S_aFor adding The emery wheel top width of work enveloping worm 16, β is the emery wheel inclination angle of processing enveloping worm 16, Corner for worm screw.

Formula has three variablees to be determined: tool rest angle of revolution in the course of processingMeshing point P is along emery wheel side surface direction From distance u of wheel top grinding and the grinding wheel spindle cross section at meshing point P place and i_aAngle theta.

One is selected in the operation interval of processingValue, the then value of a selected u, root in fully teeth height numerical range Variable θ can be drawn according to the tooth surface equation of enveloping worm 16.The tooth surface equation of enveloping worm 16 is solved as Newton iteration: by processing Practical situation may determine that, the θ value of the tooth surface equation meeting enveloping worm 16 is near 180 °, therefore at 170 ° to 190 ° In the range of obtain one group of tooth surface equation meeting enveloping worm 16ValueWill ArriveSubstitute into In formula I.e. can get a contact point on enveloping worm 16.Corresponding to same IndividualValue, takes different values by u in fully teeth height scope, can be contacted different θ values by conjugate condition equation successively, thus Multiple contact point can be obtained, contact point is connected and can form a contact line.Finally corresponding to differentValue, can obtain not Same contact line, these contact lines just constitute worm spiral face.

The failure mode of enveloping worm 16 has global failure and the flank of tooth to lose efficacy two kinds, and the global failure of enveloping worm 16 is often It is the overload owing to standing serious impact or short-term during transmission, or has than more serious load along contact line Concentrate.The flank of tooth of enveloping worm 16 lost efficacy and includes contact fatigue spot corrosion, gluing, weares and teares, fractures.And the entirety of enveloping worm 16 Lost efficacy and the flank of tooth all contact performance and greasy properties in enveloping worm 16 that lost efficacy had substantial connection, therefore, from enveloping worm 16 Contact performance and greasy property trigger evaluate enveloping worm 16 performance.

Excellent greasy property can reduce friction, alleviate abrasion, reduction temperature rise, increases the anti-bonding energy of enveloping worm 16 Power, improves the bearing capacity of enveloping worm 16, thus reaches to extend the effect in its service life.Obtain excellent greasy property, It is substantially to set up certain thickness lubricating oil film between the flank of tooth of worm screw and turbine, it is ensured that the flank of tooth under the biggest pressure, Remain able to be in the environment of hydrodynamic lubrication, or at least work in the environment of semi-liquid lubrication.

Assessment to enveloping worm 16 greasy property: and road gloomy formula theoretical according to elastic hydrodynamic lubrication sets oil film Oil film thickness is estimated by thickness geometrical factor.

k_h=v_n ^0.7/(K_12N ^0.43)

v_nIt is relative Entrainment Velocity, v_nIt is calculated by following equationWherein, (v₁)_o1 (v₂)_o1It is enveloping worm 16 and the speed of worm gear rotating disk 17, (N) at meshing point_o1It is that enveloping worm 16 instantaneous contact line is taken up an official post Law vector at Yi Dian, | N |=(N_ξ ²+N_η ²)^0.5。

It is additionally, since the oil film thickness at engaging-in end worm screw tooth root minimum, therefore selects at engaging-in end worm screw tooth root Oil film thickness evaluate enveloping worm 16 performance.

Excellent contact performance refers to that the distribution contacting line on enveloping worm 16 can not be wide, also can not be narrow, works as contact Line distribution can not be wide, also can not be narrow.When contacting line distribution and being wide, at the contact line at enveloping worm 16 job initiation angle In the outside of enveloping worm 16 flank of tooth, show that the total number of teeth in engagement between enveloping worm 16 and worm gear rotating disk 17 is less.Otherwise, contact When line distribution is narrow, contact line can tend to concentrate on the centrosymmetry face of worm gear rotating disk 17, and this will cause worm gear rotating disk 17 tooth The intensity in face reduces.

Assessment to enveloping worm 16 contact performance: with once contact line corresponding to job initiation angle worm gear rotating disk 17 points Contact point on degree circle be object to set up contact performance assessed value f (x)=| | z₁|-b₂/ 2 |, wherein, | z₁| for above-mentioned specific Contact point is to the distance in worm gear rotating disk 17 centrosymmetry face, b₂For worm gear rotating disk 17 facewidth.

Utilize the tooth surface equation optimizing software optimization enveloping worm 16 so that the oil film thickness at engaging-in end worm screw tooth root is several What coefficient is maximum, and contact performance assessed value is minimum.

After setting up enveloping worm 16 model that revolution drives structure, it is optimized for this model, finally makes envelope snail Bar 16 has excellent greasy property and contact performance, reduces the friction of enveloping worm 16, alleviates abrasion, reduction temperature rise, increases The antiscuffing capacity of enveloping worm 16, improves the bearing capacity of enveloping worm 16.And, the flank of tooth of enveloping worm 16 turns with worm gear Between the flank of tooth of dish 17, contact range is reasonable, thus extends its service life.
