Below elaborate the foregoing invention purpose and realize approach:

-weight and volume in order to reduce retarder, rely on differential rotation principle and Lever type power transmission principle, for the gear engagement that the increase that solves with velocity ratio increases is arranged, adopt to increase the number of axle and by the method that radially adds gearwheel, and fixed axis and by axial expansion gear engagement with diaxon.

-in order to reduce vibration and noise, realizing that the subtracting of Spielpassung between axle and the gear sleeve pipe closed, the axle pivot point place of diaxon uses self-aligning bearing, the influence that final gear engagement is received a parallelism error less.

In-reliability and life-span, contact the contact that realizes between the transmission key element with the rolling of movable sleeve pipe, and sleeve pipe is carried out the rerum natura treatment effect reduce friction in order to guarantee retarder.

1) adopts differential rotatablely moving and Lever type power transmission principle.

1. at the main transmission key element-gear of differential Lever type retarder, that carries out different revolutions on running shaft differentially rotatablely moves and passes on transmission.

The differential effect that rotatablely moves

● improve the engagement between the transmission key element and realize the slyness of retarder transmission.

● the transmission by differential rotation is passed on, and improves starting characteristic.

● by the differential realization that rotatablely moves, can guarantee the reliability of transmission key element and prolong the life-span.

2. adopt lever principle, realize the slyness that moment is amplified.

Adopt following principle: make the power that every fulcrum acted on the lever, avoid rising and equally distributed principle rapidly; On lever, choose fulcrum, with regard to the principle of the square amplification effect that can obtain relativity under the same power.

● the moment of torsion equalization of output terminal is assigned to each transmission key element, thereby has relatively reduced the starting torque of retarder.

● reduce inertial force, reduce the power at gear engagement place.

2) on gear engagement, reduce the velocity ratio of output terminal, thereby reduce the stress of the output gear gear teeth and the size of dwindling gear.

When output shaft bears under the same external force, to the stress analysis that gear tooth acted on.

Application example: the follower of 100HP elevator retarder

Load-up condition-elevator power P=2700Kg

Lifting-speed U=2.3m/s

Drum diameter D=1500mm

Output shaft condition d=180mm

Keyway area 240mm * 50mm

Tangential force F in the axle effect

F·d＝P·D

F·180＝2700·1500

$F=\frac{1500}{180}\·2700=225t$

So, to the specific pressure of keyway effect be;

$g=\frac{30\·{10}^3\·9.8}{240\·50\·{10}^{-6}}\≈30\mathrm{MPa}$

When the modulus m=12 of the follower of master gear retarder (A=1000mm), gear width B=240mm, the stress of respectively distinguishing of the follower gear teeth is following (referring to Fig. 2);

One district-σ _e=1550Mpa

Two districts-σ _e=863Mpa

Three districts-σ _e=395Mpa

Four districts-σ _e=173Mpa

When the modulus m=8 of the follower of differential Lever type retarder (A=300mm), gear width B=120mm, the stress of respectively distinguishing of the follower gear teeth is following (referring to Fig. 3);

Tangential force 22.5t

One district-σ _e=1230Mpa

Two districts-σ _e=412Mpa

Three districts-σ _e=138Mpa

The reason that reduces stress value is: if reduce velocity ratio, when output shaft bears same moment of torsion, along with reducing of tooth radius, just reduce in the moment of gear tooth effect.

3) utilize moment of torsion to offset effect, reduced the diameter of axle.

As shown in Figure 4, in the moment of axle dangerous section

● the moment of torsion on axle

${\mathrm{<figure-callout\; id="1"\; label="M"\; filenames="HSA00000164997100041.png"\; state="\{\{state\}\}">M</figure-callout>}}_1=9550\&CenterDot;\frac{N}{n}$

N: to the power (Kg) of axle effect

N: the rotation number (rpm) of axle

● at the resultant bending moment of dangerous section

${\mathrm{<figure-callout\; id="2"\; label="M"\; filenames="HSA00000164997100022.png,HSA00000164997100041.png"\; state="\{\{state\}\}">M</figure-callout>}}_2=\sqrt{M_x^2+{\mathrm{<figure-callout\; id="2"\; label="M\; y"\; filenames="HSA00000164997100022.png,HSA00000164997100041.png"\; state="\{\{state\}\}">M</figure-callout>}}_y^{}}$

M _x, M _y: in the vertical surface of dangerous section and the moment of flexure on the horizontal plane

● at the conversion square of dangerous section

$M_0=\sqrt{{\left({\mathrm{kM}}_2\right)}^2+{\left(k_1{M}_1\right)}^2}$

k ₁, k ₂: kinetic coefficient

-calculate at the diameter of axle of dangerous section

$d=\sqrt{\frac{M_0}{0.1{\left[\mathrm{\&sigma;}\right]}_1}}\mathrm{mm}$

[σ] ₁: the moment of flexure allowable stress Pa that presses shaft material

Axle in A-B section and C-D section only is subjected to moment of flexure, and is not subjected to moment of torsion,

So $M_0=\sqrt{{\left({\mathrm{kM}}_1\right)}^2}\&ap;{\mathrm{<figure-callout\; id="1"\; label="kM"\; filenames="HSA00000164997100041.png"\; state="\{\{state\}\}">kM</figure-callout>}}_1$

The diameter of axle that is not subjected to moment of torsion is d ₁, d then ₁＜d.

4) improve the gear engagement quality, and reduce vibration and noise.

At gear-driven vibration and noise, main relevant with the gear meshing state.The quality of gear engagement is relevant with the making precision of each gear, simultaneously also with the gear installation shaft between the mutual alignment precision very relevant.

Non-parallel degree error is as follows to The noise between the axle;

Shaft declivity is to the influence of sound press (dB)

1. at the gear sleeve pipe of differential Lever type retarder and axle, by Spielpassung, i.e. h ₆, g ₆, f ₇, e ₈, d ₉Come combination, and adjust the parallelism error of axle, therefore can improve the gear meshing quality.

2. the pivot point of diaxon is as self-aligning spherical bearing fulcrum, and therefore the inclination of axle is adjusted in 2 °～5 °, and improves the gear engagement quality, and reduces vibration and noise.

5) utilize movable sleeve tubular construction and rerum natura effect, reduce the sliding friction torque between sleeve pipe and the axle.

1. realize the relative differential motion of sleeve pipe, reduce friction coefficient and friction torque to axle journal.

The peripheral velocity of axle is V ₁, the linear speed of sleeve pipe is V ₂

Friction factor when sleeve pipe carries out differential motion to axle is μ '

Friction factor when sleeve pipe is fixed is μ

${\mathrm{\&mu;}}^{\&prime;}=\mathrm{\&mu;}\&CenterDot;\frac{V_1}{\sqrt{{\mathrm{<figure-callout\; id="1"\; label="V"\; filenames="HSA00000164997100041.png"\; state="\{\{state\}\}">V</figure-callout>}}_1^2+{\mathrm{<figure-callout\; id="2"\; label="V"\; filenames="HSA00000164997100022.png,HSA00000164997100041.png"\; state="\{\{state\}\}">V</figure-callout>}}_2^2}}$ In the formula, $\frac{V_1}{\sqrt{{\mathrm{<figure-callout\; id="1"\; label="V"\; filenames="HSA00000164997100041.png"\; state="\{\{state\}\}">V</figure-callout>}}_1^2+{\mathrm{<figure-callout\; id="2"\; label="V"\; filenames="HSA00000164997100022.png,HSA00000164997100041.png"\; state="\{\{state\}\}">V</figure-callout>}}_2^2}}<1$

V ₂Be worth greatly more, this value is more little.

Because of V in differential Lever type retarder ₂＞V ₁, μ ' is less than μ.

If the fulcrum radius is R, the diameter of axle is d, then

During the sleeve pipe rotation, the friction torque at fulcrum place is

When sleeve pipe did not rotate, the friction torque at fulcrum place was

∴ $M_{}$ ${}_1={\mathrm{<figure-callout\; id="2"\; label="M"\; filenames="HSA00000164997100022.png,HSA00000164997100041.png"\; state="\{\{state\}\}">M</figure-callout>}}_2\&CenterDot;\frac{V_1}{\sqrt{{\mathrm{<figure-callout\; id="1"\; label="V"\; filenames="HSA00000164997100041.png"\; state="\{\{state\}\}">V</figure-callout>}}_1^2+{\mathrm{<figure-callout\; id="2"\; label="V"\; filenames="HSA00000164997100022.png,HSA00000164997100041.png"\; state="\{\{state\}\}">V</figure-callout>}}_2^2}}$

∴M ₁＜M ₂

2. utilize the rerum natura effect, reduce the sliding friction torque between sleeve pipe and the axle.

Gear sleeve pipe at differential Lever type retarder with axle is, according to the movable sleeve tubular construction, during the reduction sliding friction torque, sleeve pipe is used complex coating technology and heating in vacuum oil impregnate technology and reduced friction factor, therefore reduce sleeve pipe and the wearing and tearing of axle and the reliability and the life-span of prolongation retarder.

● significantly reduce friction factor.

Be 0.0075 under the lubricating condition

● increase critical operating conditions.

P _max?40MPa

V _max?6m/s

P·V＝40MPa·6m/s＝240Mpa·m/s
