A lokacin da ƙira ko sayen maɓuɓɓugan ruwa don kowane aikace-aikace, fahimta Tsabtakar da bazara yana da mahimmanci. Tolerances are the allowable deviations in a spring's dimensions, Abubuwan kayan abu, ko halayen aikin daga ƙirar da aka ƙayyade. Wadannan karkacewar tabbatar da cewa ayyukan bazara kamar yadda aka yi niyya, Ko da lokacin da ɗan bambanci yana faruwa yayin masana'antu ko a ƙarƙashin yanayi daban-daban.
Wannan shafin zai bincika abin da hakwar bazara suke, Abubuwan da ke faruwa suna tasiri su, Kuma me yasa suke da mahimmanci don tabbatar da abin dogara.
Menene hakoran bazara?
A cikin mahallin maɓuɓɓugan ruwa, tolerances are the permissible range of variation in a spring's physical and mechanical properties. Wadannan bambance-bambancen na iya hadawa:
- Girma: Diamita waya, coil diamita, tsawon kyauta, ko jimlar adadin coils.
- Kaya: Karfi da bazara a wani takamaiman matsawa, ƙarin teleho, ko dattaki.
- Farashi: The spring's stiffness or resistance to deformation.
- Gama: Runduna na ciki ko ingancin (E.g., Plating ko fenti).
Misali, Idan an ƙayyade lokacin bazara tare da tsawon lokaci na 50 mm ± 0.5 mm, Mai kera ya tabbatar da ainihin lokacin bazara ya fadi a tsakanin kewayon 49.5 mm to 50.5 mm.
Me yasa yasa aka yarda da hakoran bazara?
Tsabta na bazara yana da mahimmanci ga dalilai da yawa:
1. Tabbatar da daidaituwa
Springs galibi sashe na taron hadaddun. If the spring's dimensions or performance deviate too much from specifications, Zai iya dacewa ko aiki yadda yakamata a cikin aikace-aikacen, kai ga gazawar injina.
2. Dogaro da aminci

Dalilai da yawa suna tantance hakuri na jure wa bazara:
1. Nau'in bazara
Daban-daban na bazara (matsawa, ƙarin teleho, trission, ko masu amfani da maɓuɓɓuka) da hakora na musamman saboda tsarinsu da aikinsu. Misali:
- Springs Springs yawanci suna da haƙuri ga tsayin daka kyauta da kaya.
- Tsawo Springs na iya yin haƙuri mai haƙuri don tashin hankali.
2. Abu
Kayan da aka yi amfani da su don kera bazara ta shafi wadatar hakuri. Misali, Karfe mai tsayi na iya jure wa mai haƙuri da haƙuri fiye da kayan masarufi.
3. Masana'antu
