K129減速機安裝方法:

K129減速機的固定:臥式底腳K129減速機螺栓規格M36。K129減速機螺栓/螺母擰緊扭矩強度等級8.8,螺栓規格M36擰緊扭矩2500N.m。

K129減速機安裝條件:不當安裝可能造成減速器及減速電機損失還可能造成財產損失。檢查下列各點要求是否得到滿足:減速電機銘牌上標注的電壓與電源電壓一致、驅動裝置在運輸或者倉儲過程中未遭受損壞;確保滿足下列規定:對于標準減速器:環保溫度符合技術資料、銘牌以及章節“潤滑油”中潤滑油中的規定。周圍不得存在有害油污、酸、氣體、蒸汽、放射性環境等;對于特殊形式:傳動裝置要根據環境條件來設計。請注意銘牌上的規定;對于蝸輪蝸桿減速器:不能對蝸輪蝸桿減速器施加過大的逆向外部慣性矩,以免損壞減速器;必須徹底清除輸出軸和法蘭表面上的防銹劑、污垢或類似污染。必須使用常用的溶劑。不得讓溶劑進入到軸密封環的密封唇上,否則會損壞材料;在腐蝕性的環境條件請保護好輸出軸端面的油封以防損壞。齒輪減速電機

軸端公差:直徑公差按照GB1800~1804規定、直徑≤50mm的實心軸,采用GBk6、直徑≥50mm的實心軸,采用GBm6、空心軸,采用GBH7、中心孔按照GB/T145標準C型式。

法蘭端公差:對中軸肩的公差依據 GB1800~1804標準、b1≤230mm時采用GBj6、b1>230mm時采用GBh6。

K129減速機或K129減速電機只能以訂購的安裝位置進行安裝/裝配。請注意銘牌上的規定。支撐安裝位置必須具備下列特征:、平穩、防震、·抗彎,剛性好;地腳和法蘭固定所允許的最大平面誤差(參考值參見 ISO 1101標準):減速器規格≤67:最大0.4mm 、減速器規格77-107:最大0.5mm、減速器規格137-147:最大0.7mmm、安裝時不要將K129減速機地腳和安裝法蘭同時擰緊,以免相互較勁,且注意其許用徑向力和軸向力!計算許用徑向力與軸向力時要注意K129減速機樣本中的“選型”章節。K系列減速機

K129減速機存放注意事項:若存放時間超過6個月,BOSERL公司建議采用“長期存放”設計規格。此種設計規格的減速機標識有相應的標簽。

溫帶(亞洲、非洲、中/南美洲、澳大利亞、新西南、溫帶地區除外):1.置于包裝箱內,且與干燥劑、濕度指示器一同密封在塑料包裝中。要求化學處理用于防蟲、防霉。有頂棚,防雨,雪,無外部沖擊。半年,需定期檢查包裝情況和濕度(相對濕度<50%);2.敞開,有頂棚、恒溫、恒濕環境(5°C<0<60°C,相對濕度<50%)。要求沒有溫度上的起伏突變,帶過濾通風設備(防塵、泥)。防濕氣腐蝕和外部沖擊。半年或更長,需定期檢查:清潔、機械損傷和防腐情況。

溫帶(歐洲、美國、加拿大、中國和俄羅斯、熱帶地區除外):1.置于包裝箱內,且與干燥劑、濕度指示器一同密封在塑料包裝中。要求有頂棚、防雨、雪,無外部沖擊。半年,需定期檢查包裝情況和濕度(相對濕度<50%);2.敞開,有頂棚、恒溫、恒濕環境(5°C<0<60°C,相對濕度<50%)。要求沒有溫度上的起伏突變,帶過濾通風設備(防塵、泥)。防濕氣腐蝕和外部沖擊。半年或更長,需定期檢查:清潔、機械損傷和防腐情況。直角減速機

K129減速機的潤滑油混合有防腐劑(揮發性腐蝕抑制劑)。注意,腐蝕劑僅在-25°C-+50°C范圍內有效。另外,法蘭表面與軸端都應涂防腐劑。長期存放時,要滿足以下所列的存放條件:1.K129減速機包裝必須由一家經驗豐富的公司針對的采用合格的包裝材料進行;2.BOSERL公司建議,根據安裝的位置存放K129減速機。

存放一段時間后,開機調試前,K129減速機必須保持密封,以避免防腐劑揮發。K129減速機出廠時會根據安裝位置(M1..M6)進行加油。K129減速機運行前,務必檢查油位!
