齒輪的失效方式

　　齒輪的失效方式

1
、齒麵磨損

關guan於yu開kai式shi齒chi輪lun傳chuan動dong或huo含han有you不bu清qing潔jie的de光guang滑hua油you的de閉bi式shi齒chi輪lun傳chuan動dong，因yin為wei齧nie合he齒chi麵mian間jian的de相xiang對dui滑hua動dong
，使shi一yi些xie較jiao硬ying的de磨mo粒li進jin入ru了le摩mo擦ca外wai表biao，從cong而er使shi齒chi廓kuo改gai動dong
，側ce隙xi加jia大da，以yi至zhi於yu齒chi輪lun過guo度du減jian薄bo導dao致zhi齒chi斷duan。一yi般ban情qing況kuang下xia


，隻zhi有you在zai光guang滑hua油you中zhong攙chan雜za磨mo粒li時shi
，才cai會hui在zai運yun轉zhuan中zhong引yin起qi齒chi麵mian磨mo粒li磨mo損sun。

2、齒麵膠合

、疲憊點蝕

相xiang互hu齧nie合he的de兩liang輪lun齒chi觸chu摸mo時shi
，齒chi麵mian間jian的de作zuo用yong力li和he反fan作zuo用yong力li使shi兩liang作zuo業ye外wai表biao上shang發fa生sheng觸chu摸mo應ying力li
，因yin為wei齧nie合he點dian的de位wei置zhi是shi改gai變bian的de

，且qie齒chi輪lun做zuo的de是shi周zhou期qi性xing的de運yun動dong
，所suo以yi觸chu摸mo應ying力li是shi按an脈mai動dong循xun環huan改gai變bian的de。齒chi麵mian長chang期qi在zai這zhe種zhong交jiao變bian觸chu摸mo應ying力li作zuo用yong下xia，在zai齒chi麵mian的de刀dao痕hen處chu會hui呈cheng現xian小xiao的de裂lie紋wen，跟gen著zhe時shi刻ke的de推tui移yi，這zhe種zhong裂lie紋wen逐zhu漸jian在zai表biao層ceng橫heng向xiang擴kuo展zhan，裂lie紋wen構gou成cheng環huan狀zhuang後hou，使shi輪lun齒chi的de外wai表biao發fa生sheng細xi小xiao麵mian積ji的de剝bo落luo而er構gou成cheng一yi些xie疲pi憊bei淺qian坑keng。

4、輪齒折斷

5
、齒麵塑性變形

在衝擊載荷或重載下，齒麵易發生部分的塑性變形，從而使漸開線齒廓的曲麵發生變形。
