Transmissions angularite depanaj

torsyonèl Vibwasyon

Lè nap Peye Transmissions U-Joint Operasyon Ang

Aksyon an nan yon transmissions ak yon jwenti inivèsèl nan de pwent k ap travay nan yon ang rezilta nan yon mouvman spesifik. transmissions la pral pi vit ak ralanti de fwa pou chak revolisyon. Si ang yo ap travay nan de pwent nan arbr a se inegal, torsyonèl rezilta Vibration. Vibration torsyonèl sa a pral yo gen tandans anile tèt li soti si toude jwenti ang k ap travay yo egal.

Kalite Bri

se bri oswa Vibration ki fèt sèlman nan vitès wout sèten ak diminye kòm ogmante vitès jeneralman ki te koze pa ang inegal k ap travay nan jwenti transmissions. pouvwa Bri oswa Vibration ki se ki pèsistan nan tout seri a vitès ak varye nan entansite ak chanjman nan vitès ki te koze pa dezekilib drivelines, tanbou fren dezekilib oswa disk, oswa drivelines ak jwenti inivèsèl soti nan faz.

Chèk preliminè

Fè chèk nan bagay sa yo anvan yo pran lekti ang:

  1. Check companion flange or yoke nut for looseness and torque to proper specification if necessary.
    transmissions glise jwenti
  2. Driveline slip joints that do not have the arrows or other markings pointing to each other will result in the driveline universal joints being out of phase. Nan yon lòt sans, the transmission universal joint may be turned one spline or more to the right or left of being aligned with the universal joint at the opposite end of the driveline.
    • Some computer designed drivelines are purposely built with U-joints out of phase. Check manufacturer’s specifications for proper setting. Epitou, check closely to make certain no twist has occurred to the tubing, causing these two joints to be out of phase Make sure the slip joint works freely and is not bound or seized. Slip joints must absorb axle housing movements.
  3. Unbalanced drivelines can cause vibration that occurs throughout the speed range of vehicle and varies in intensity with a change of speed. The driveline may be at fault in respect to balance and concentricity. A quick field check to determine driveline balance can be made by securing a small piece of metal or similar weight with a hose clamp to the front of the tube where the splined shaft is welded. Road test the vehicle and continue to move the weight around the tube until the balance point is found and vibration disappears or is minimized.
    dezekilib transmissions
    Drivelines yo dynamique balanse gen entansyon vitès wotasyon yo epi yo pa vitès enfini. Se konsa, vibration can be expected when this rotational velocity is exceeded. Check concentricity of driveline by mounting on lathe centers and dial indicating. Tcheke espesifikasyon fabrikan an pou alokasyon runout.
  4. sipò Engine ke yo chire, kase oswa ki lach, and mounting pads that are worn or deteriorated must be corrected to restore the engine suspension to its original vibration tolerance.

Lè w ap pran Readings

plain, wing and flange driveline joint
plain driveline joint
universal joint

Take readings with protractor from machined surfaces of yokes or companion flanges. Plain, zèl oswa kalite bride jwenti ka rankontre. Some will require partial disassembly to obtain accurate readings.

Sou jwenti di ki plenn, it may be necessary to remove the bearing cap. Lè w ap pran lekti, make sure the universal joint is in a vertical plane. At the rear axle, take readings from a machined surface differential carrier that is in the same plane as the axle pinion shaft, oswa nan sifas machinèd ki se pèpandikilè ak arbr lye, kèlkeswa sa ki pi fasil.

Si Vibration rive pandan y ap opere vid, take readings in empty condition. Si li rive lè chaje, take readings when loaded. When it is necessary to measure driveline lengths, measure from joint center to joint center

espesifikasyon fabrikan an ta dwe swiv lè yo fè premye chèk angularite. Some manufacturers have found it necessary to vary from the ideal due to geometrical limitations. If vibration persists after adhering to manufacturer’s specifications, contact the manufacturer’s representative.

Angularite Chèk - èl Paralèl oswa yon jouk bèf fèt

  1. Single Aks Machin
    • transmisyon ang – Take reading of transmission angle. This angle is the angle to which the rear axle joint angle must match. The transmission angle will have a declination reading of from 0 to 5 degre nan pifò ka yo.
      transmisyon ang lekti
    • Aks ang. Take reading either from machined surface of axle housing or pinion bearing retainer. This angle must be within one degree of the transmission angle.
      • egzanp: If transmission angle reading is 3 degrees down to the rear, the rear axle angle should be 3 degre moute.
  2. Tandem Essieux oswa Machin ak Inite Oksilyè
    • Pran transmisyon lekti ang.
    • Take reading from joint of front tandem axle or auxiliary joint. This reading should be within one degree of transmission angle.
      • Remak: The rear joint of front tandem axle will be the same as the front joint.
    • Pran lekti nan ang jwenti a tandem aryè aks, or axle to rear of auxiliary. This angle must be within one degree of transmission angle.

Plan kad Nasyonzini Travay Ang Limit (Paralèl)

jwenti Inivèsèl gen yon maksimòm ang k ap travay, ki depann sou kalite ak envantè. Li rekòmande pou jwenti ang lan k ap travay pou paralèl asanble jwenti pa gen dwa depase 8 degre pou drivelines prensipal plis pase 40″ lontan. Pou drivelines prensipal anba 40″ ang a maksimòm pa ta dwe depase Length (L) divize pa 5. (limit sa a pa aplike nan interaxle drivelines.)

egzanp: Pou yon 35″ transmissions, the maximum joint working angle would be 35 plis 5 oswa 7degrees. This working angle must not be exceeded.

Place protractor on driveline to obtain angle of driveline from transmission to axle. The difference between the driveline angle and the joint angle is the joint working angle. For instance, si transmisyon a se 3 degre desann, and the driveline angle is down 7 degre, the transmission joint working angle is 7 mwens 3 oswa 4 degre.
Sou kondwi tandem oswa enstalasyon oksilyè, take readings in the same manner, comparing the universal joint angles to the driveline angle to which it is attached.

Angularity Checks – Non-Parallel Compensating Angles or Flanges or Yokes

Avèk machin kout baz wou ki gen yon longè transmissions minimòm soti nan transmisyon aks, se transmissions la oblije opere nan ang k ap travay trè grav sou kèk enstalasyon. Sa a tou aplike nan interaxle drivelines. Sa yo k ap travay grav jwenti ang pwovoke Vibration. Pou diminye k ap travay ang, se esyeu la panche anwo jouk mitan an lye arbr ak transmisyon Mainshaft mitan kwaze Midway ant sant sa yo jwenti.

angularity check

Avèk aks tandem kondwi, the rearward axle is tilted upward until its pinion shaft centerline and forward axle pinion shaft centerline intersect midway between joint centers.

Lè n ap kalkile ki pa paralèl enstalasyon jwenti, it is necessary to take the driveline angle readings as well as transmission and axle angle readings.

  1. Single Aks Machin
    • Pran lekti ang transmisyon
    • Pran ang transmissions
    • Pran lekti ang aks jwenti
    • Yo kalkile pou ang kòrèk:
      • The difference between the driveline angle and the transmission angle will be the transmission joint working angle.
      • The difference between the driveline angle and the axle angle will be the axle joint working angle.
      • The two working angles of transmission and axle must be equal.
      • egzanp:
        transmisyon se 3 degre desann
        transmissions se 7.5 degre desann
        Aryè aks se 12 degre desann
        Se konsa 7.5 mwens 3 egal 4.5 degre
        12 mwens 7.5 egal 4.5 degre, giving 4.5 equal working angles
  2. Tandem Essieux oswa Machin ak Inite Oksilyè – When taking readings on tandem drive axles or between auxiliary and rear axle, the same principles apply as with single axle vehicles. Take readings between transmission and front tandem axle, or auxiliary. Take readings between axles or between auxiliary and axle. Nan yon lòt sans, take angle readings for each set of universal joints

Plan kad Nasyonzini Travay Ang Limit (Ki pa Peye-Paralèl)

Li rekòmande pou maksimòm jwenti ang lan k ap travay pou asanble ki pa paralèl jwenti pa gen dwa depase longè a transmissions prensipal divize pa 10. Pa egzanp, si longè a transmissions prensipal la se 55, maksimòm ang lan k ap travay jwenti se 55 divize pa 10 oswa 5.5 degre. (limit sa a pa aplike nan interaxle drivelines.)

Aks Ajisteman

ang aks pouvwa jeneralman ap ajiste pa youn nan fason sa yo, ki depann sou kalite a nan aks.

  1. Ajiste branch koupl, si kalite reglabl.
  2. Add to or reduce length of non-adjustable torque rods.
  3. Add or reduce the number of shims behind torque rod brackets.
  4. Use correct amount of wedge shims under spring to axle pad.

Sispansyon - Lye aks Ang

Li pral fè ti kras oswa ki pa gen chanjman nan aks ang lye ak kalite sispansyon ki gen yon mouvman paralelogram. Sa yo pèmèt enceintes diferans pou avanse pou pi leve, li desann nan yon vètikal dwat pandan yon operasyon.
Sispansyon pa gen yon mouvman paralelogram pral pèmèt arbr esyeu lye fluktue nan yon arc ak, kidonk toujou ap chanje lye ang arbr pandan yon operasyon. Ou ka jwenn yon kantite lajan pou Vibration varye yo rive ki te koze pa ang k ap travay nan jwenti yo inivèsèl ke yo te ti tan inegal.
Single kondwi machin aks gen ti kras oswa ki pa gen chanjman nan ang aks lye pandan yon operasyon.
