Tuam Tshoj lwm tus neeg precision miniature ob theem spur iav compound spur iav

Spur iav thiab helical iav yog ob qho tib si hom iav siv hauv cov tshuab tshuab, tab sis lawv muaj cov yam ntxwv sib txawv thiab haum rau kev siv sib txawv. Ntawm no yog qhov sib piv ntawm ob:

Spur Gears

Yam ntxwv:
1. Cov hniav sib dhos: Cov hniav yog ncaj thiab sib npaug rau lub iav axis.
2. Load Distribution: Load yog faib hla ib kab ntawm kev sib cuag.
3. Efficiency: High efficiency vim tsawg zawv zawg ntawm cov hniav.
4. Suab nrov: nrov nrov ntawm kev kub ceev vim yog kev sib koom ua ke ntawm cov hniav.
5. Kev tsim khoom: Yooj yim thiab pheej yig dua los tsim khoom.
6. Axial Load: Tsis muaj axial thrust load yog generated.

Qhov zoo ntawm Spur Gear:
● Yooj yim tsim thiab yooj yim los tsim.
● Kev ua haujlwm siab vim muaj kev sib txhuam qis.
● Siv tau rau cov ntawv thov ceev qis mus rau nruab nrab.
● Tsis muaj axial thrust yog generated, simplifying bearing tsim.

Disadvantages ntawm Spur iav
● Suab nrov ntawm kev kub ceev.
● Tsawg load-nqa peev piv rau helical iav.
● Sudden loading ntawm cov hniav tuaj yeem ua rau hnyav dua thiab tsim kua muag.

Helical iav

Yam ntxwv:
1. Cov hniav sib dhos: Cov hniav raug txiav ntawm lub kaum sab xis rau lub iav qhov axis, tsim ib lub helix.
2. Load Distribution: Load faib ntau cov hniav, muab kev ua haujlwm zoo dua thiab ntsiag to.
3. Kev ua haujlwm zoo: Kev ua haujlwm qis dua me ntsis dua li cov iav spur vim muaj kev sib txhuam ntau dua.
4. Suab nrov: Kev ua haujlwm ntsiag to vim kev sib koom ua ke ntawm cov hniav.
5. Kev tsim khoom: Ntau qhov nyuaj thiab kim los tsim khoom.

6. Axial Load: Tsim axial thrust load uas yuav tsum tau haum rau hauv cov qauv tsim.

Qhov zoo ntawm Helical iav:
● Kev ua haujlwm du thiab ntsiag to, zoo tagnrho rau kev siv ceev ceev.
● Lub peev xwm thauj khoom ntau dua vim qhov kev faib tawm ntawm kev thauj khoom hla ntau cov hniav.
● Zoo meshing ntawm cov hniav, txo kev hnav thiab ncua kev ua neej.

Disadvantages ntawm Helical iav:
● Ntau qhov nyuaj thiab raug nqi tsim khoom.
● Tsim cov axial thrust, yuav tsum tau ua kom muaj zog ntau dua.
● Kev ua haujlwm tsawg dua vim muaj kev sib txhuam ntxiv.
