Hanyar Nazari da Aunawa ta Tsarin

Tsarin Kimanta Kusurwa na R (Dokar Yankewa ta Masana'antu):

R ≈ 1.5–3.0 × kauri bango (t)

Misali:
Idan kauri bango shine 5mm → kusurwar R ≈ 7.5mm–15mm

Hanyar Auna Fili

Ana iya duba kusurwar R ta hanyar:

✔ Kayan aikin auna radius
✔ Samfuran auna da'ira
✔ Injin aunawa mai daidaita bayanan martaba

Me yasa R Angle yake da mahimmanci?

Radius na kusurwa yana shafar:

✔ Ƙarfi - yana rage yawan damuwa
✔ Rufi — yana tabbatar da rufewar galvanized a gefuna
✔ Walda — yana inganta ingancin haɗakarwa
✔ Kayan kwalliya - kyakkyawan tsari
✔ Haɗawa - yana shafar dacewar ramin da girman mahaɗin

Abin da za a Duba Lokacin Siyan Karfe Mai Bukatar Angle na R

Masu saye ya kamata su kimanta:

① Tabbatar da bin ƙa'idodin da aka tsara

Tambayi mai samar da kayayyaki wane tsari da kuma mizani suke bi
(EN10210, EN10219, GB, JIS, BS suna da siffofi daban-daban na kusurwa).

② Tabbatar da cewa Radius ya cika buƙatun aikace-aikacen

Babban R → santsi, ƙarfi, da sauƙin shafa

Ƙananan gefuna masu kaifi, sun dace da masu haɗawa

③ Duba Kauri Bango da Daidaita R

Radius na kusurwa yana daidai da kauri na bango - ƙaramin radius ga bututu masu kauri sau da yawa yana nuna rashin tsari.

④ Tabbatar da Aunawa ta Gaskiya

Buƙata:

Bayanan gwajin ma'aunin radius

⑤ Kula da Bayan Aiki

Yin amfani da galvanizing mai zafi, hudawa, ko injina yana buƙatar madaidaicin radius na kusurwa don kwararar shafi da kwanciyar hankali na tsarin.

Kammalawa

Kusurwar R ba wani abu ne na kwalliya ba.
Yana inganta aikin kwakwalwa, yana ƙarfafa tsarin rigakafi,rayuwar hidima, da kuma daidaiton shigarwa.
