Wprowadzenie do normy GB\/T 9145-2003<\/h2>\n

Niniejsza norma okre\u015bla wymiary graniczne dla gwint\u00f3w metrycznych og\u00f3lnego przeznaczenia o \u015bredniej dok\u0142adno\u015bci w preferowanej serii, zapewniaj\u0105c zmienno\u015b\u0107 i wydajno\u015b\u0107 w zespo\u0142ach mechanicznych. Obejmuje ona gwinty zgrubne i drobnozwojowe do zastosowa\u0144 wewn\u0119trznych i zewn\u0119trznych, z tolerancjami stosowanymi przed na\u0142o\u017ceniem cienkich pow\u0142ok.<\/p>\n<\/div>\n

\n

Zakres<\/h2>\n

Norma GB\/T 9145-2003 definiuje wymiary graniczne gwint\u00f3w metrycznych o \u015bredniej tolerancji dok\u0142adno\u015bci i preferowanych seriach, maj\u0105cych zastosowanie w og\u00f3lnych zastosowaniach in\u017cynieryjnych. Gwarantuje ona, \u017ce \u200b\u200bprofile gwint\u00f3w nie przekraczaj\u0105 maksymalnego stanu materia\u0142u okre\u015blonego przez profile podstawowe i pozycje tolerancji. Ma to kluczowe znaczenie dla element\u00f3w z\u0142\u0105cznych w bran\u017cach wymagaj\u0105cych niezawodnego po\u0142\u0105czenia bez zak\u0142\u00f3ce\u0144, zw\u0142aszcza po platerowaniu.<\/p>\n

    \n
  • Stosuje si\u0119 do gwint\u00f3w przed na\u0142o\u017ceniem cienkich pow\u0142ok, np. galwanicznych.<\/li>\n
  • Po na\u0142o\u017ceniu pow\u0142oki profile musz\u0105 pozosta\u0107 w pozycjach H lub h.<\/li>\n
  • Koncentruje si\u0119 na \u015brednich d\u0142ugo\u015bciach sprz\u0119gania, zapewniaj\u0105c zr\u00f3wnowa\u017con\u0105 wytrzyma\u0142o\u015b\u0107 i \u0142atwo\u015b\u0107 produkcji.<\/li>\n<\/ul>\n<\/div>\n
    \n

    Og\u00f3lne wymiary graniczne<\/h2>\n

    \u017baden punkt na profilu podstawy gwintu nie mo\u017ce przekracza\u0107 maksymalnego profilu jednostki dla danego kszta\u0142tu i tolerancji. W przypadku gwint\u00f3w platerowanych, rzeczywiste kontury po platerowaniu nie mog\u0105 przekracza\u0107 pozycji H\/h. Zapobiega to nadmiernemu dokr\u0119ceniu lub uszkodzeniu zespo\u0142\u00f3w. Uwaga: Tolerancje s\u0105 odpowiednie dla cienkich pow\u0142ok; grubsze pow\u0142oki wymagaj\u0105 korekty.<\/p>\n<\/div>\n

    \n

    Gwinty wewn\u0119trzne o grubym skoku<\/h2>\n

    Dla \u015bredniej precyzji, d\u0142ugo\u015b\u0107 w\u0142\u0105czenia jest \u015brednia. Strefy tolerancji: 5H dla d \u2264 1,4 mm; 6H dla d > 1,4 mm. Granice dla \u015brednicy podzia\u0142owej D2<\/sub> i mniejszej \u015brednicy D1<\/sub> zapewni\u0107 w\u0142a\u015bciwe dopasowanie do gwint\u00f3w zewn\u0119trznych.<\/p>\n

    Introduction to GB\/T 9145-2003 Standard<\/h2>\r\nThis standard specifies limit dimensions for general-purpose metric screw threads of medium accuracy in the preferred series, ensuring interchangeability and performance in mechanical assemblies. It covers coarse and fine pitch threads for internal and external applications, with tolerances applied before plating for thin coatings.\r\n\r\n<\/div>\r\n
    \r\n

    Scope<\/h2>\r\nGB\/T 9145-2003 defines the limit dimensions for metric screw threads with medium tolerance precision and preferred series, applicable to general engineering purposes. It ensures that thread profiles do not exceed the maximum material condition defined by basic profiles and tolerance positions. This is crucial for fasteners in industries requiring reliable mating without interference, especially post-plating.\r\n
      \r\n \t
    • Applies to threads before thin coatings like electroplating.<\/li>\r\n \t
    • Post-plating, profiles must stay within H or h positions.<\/li>\r\n \t
    • Focuses on medium engagement lengths for balanced strength and manufacturability.<\/li>\r\n<\/ul>\r\n<\/div>\r\n
      \r\n

      General Limit Dimensions<\/h2>\r\nNo point on the thread root profile shall exceed the maximum entity profile per basic form and tolerance. For plated threads, actual contours post-plating must not surpass H\/h positions. This prevents over-tightening or failure in assemblies. Note: Tolerances suit thin platings; heavier coatings require adjustments.\r\n\r\n<\/div>\r\n
      \r\n

      Coarse Pitch Internal Threads<\/h2>\r\nFor medium precision, engagement length is medium. Tolerance zones: 5H for d \u2264 1.4 mm; 6H for d > 1.4 mm. Limits for pitch diameter D2<\/sub> and minor diameter D1<\/sub> ensure proper fit with external threads.\r\n

      FAQ<\/h2>\r\n

      What tolerance zones apply to coarse internal threads?<\/h3>\r\n5H for diameters \u22641.4 mm; 6H for >1.4 mm, ensuring medium precision fit.\r\n

      How does plating affect thread dimensions?<\/h3>\r\nTolerances are pre-plating; post-plating profiles must not exceed H\/h positions for thin coatings to maintain assembly.\r\n

      Why use fine pitch threads?<\/h3>\r\nThey provide better vibration resistance and finer adjustments, with stronger cores per limits in tables 3 and 4.\r\n

      What is medium engagement length?<\/h3>\r\nIt balances thread strength and cost; use table values for specific ranges to avoid over- or under-engagement.\r\n

      How to interpret root radius?<\/h3>\r\nMin values per GB\/T 197-2003 reduce stress; essential for fatigue-prone applications.\r\n

      Are these limits for all materials?<\/h3>\r\nYes, but adjust for special platings; consult standard for heavy coatings requiring oversized threads.\r\n\r\n<\/div>\r\n ","_et_gb_content_width":"","footnotes":""},"categories":[220],"tags":[],"class_list":["post-5757","post","type-post","status-publish","format-standard","hentry","category-technical-documentation-and-references"],"_links":{"self":[{"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/posts\/5757","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/comments?post=5757"}],"version-history":[{"count":3,"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/posts\/5757\/revisions"}],"predecessor-version":[{"id":5760,"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/posts\/5757\/revisions\/5760"}],"wp:attachment":[{"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/media?parent=5757"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/categories?post=5757"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/korea-transmission.com\/pl\/wp-json\/wp\/v2\/tags?post=5757"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
