Drum couplings therefore tolerate a certain degree of angular misalignment. Because the three overhead crane drum couplings have different structures, their permissible angular deviations are also different.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>WJ\u7403\u9762\u6eda\u5b50\u8054\u8f74\u5668\uff1a<\/strong> \u5f53\u8f74\u7ebf\u503e\u659c\u65f6\uff0c\u7403\u9762\u6eda\u5b50\u5728\u6c9f\u69fd\u5185\u4f1a\u79fb\u52a8\u5230\u4e0d\u7a33\u5b9a\u7684\u4f4d\u7f6e\uff0c\u8fd9\u4f1a\u5bfc\u81f4\u566a\u97f3\u548c\u78e8\u635f\u3002\u6700\u5927\u5141\u8bb8\u89d2\u5ea6\u504f\u5dee\u4e3a1.5\u00b0\u3002<\/li>\n\n\n\n<li><strong>WZL\u7403\u5f62\u94f0\u63a5\u8054\u8f74\u5668\uff1a<\/strong> \u8fd9\u79cd\u8054\u8f74\u5668\u7684\u5de5\u4f5c\u539f\u7406\u7c7b\u4f3c\u4e8e\u4e07\u5411\u8282\u3002\u5f53\u8f74\u7ebf\u503e\u659c\u65f6\uff0c\u7279\u6b8a\u7684\u952e\u69fd\u4f1a\u8865\u507f\u89d2\u5ea6\u4f4d\u79fb\u3002\u867d\u7136\u6ed1\u52a8\u91cf\u589e\u5927\uff0c\u4f20\u52a8\u6548\u7387\u964d\u4f4e\uff0c\u4f46\u5185\u90e8\u53d7\u529b\u60c5\u51b5\u53d8\u5316\u4e0d\u5927\u3002\u6700\u5927\u5141\u8bb8\u89d2\u5ea6\u504f\u5dee\u4e3a3\u00b0\u3002<\/li>\n\n\n\n<li><strong>\u76f4\u6d41\u51a0\u72b6\u9f7f\u8f6e\u8054\u8f74\u5668\uff1a<\/strong> \u7531\u4e8e\u5f84\u5411\u5b9a\u4f4d\u4f4d\u7f6e\u4e0e\u5185\u90e8\u9f7f\u8f6e\u526f\u4e4b\u95f4\u5b58\u5728\u4e00\u5b9a\u8ddd\u79bb\uff0c\u8f74\u7ebf\u503e\u659c\u4f1a\u5f71\u54cd\u9f7f\u8f6e\u556e\u5408\u3002\u5141\u8bb8\u7684\u89d2\u5ea6\u504f\u5dee\u53d7\u9f7f\u8f6e\u526f\u95f4\u9699\u7684\u9650\u5236\uff0c\u4e3a0.5\u00b0\u3002<\/li>\n<\/ul>\n\n\n\n<p>\u5728\u8fd9\u4e09\u79cd\u7c7b\u578b\u4e2d\uff0c\u7403\u5f62\u94f0\u63a5\u8054\u8f74\u5668\u5bf9\u8d77\u91cd\u673a\u5b89\u88c5\u7cbe\u5ea6\u7684\u8981\u6c42\u6700\u4f4e\u3002<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"2-2-maintenance\">2.2 \u7ef4\u62a4<\/h3>\n\n\n\n<p>\u8054\u8f74\u5668\u7ef4\u62a4\u7684\u5173\u952e\u5728\u4e8e\u6da6\u6ed1\uff0c\u56e0\u6b64\u5b9a\u671f\u6da6\u6ed1\u5fc5\u4e0d\u53ef\u5c11\u3002\u4ece\u7ed3\u6784\u4e0a\u770b\uff0c\u9700\u8981\u6da6\u6ed1\u7684\u533a\u57df\u4e3b\u8981\u662f\u626d\u77e9\u4f20\u9012\u90e8\u4ef6\u548c\u5f84\u5411\u627f\u8f7d\u90e8\u4ef6\u3002 <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>WJ\u7403\u9762\u6eda\u5b50\u8054\u8f74\u5668\uff1a<\/strong> \u7403\u9762\u6eda\u5b50\u65e2\u4f20\u9012\u626d\u77e9\u53c8\u627f\u53d7\u5f84\u5411\u8f7d\u8377\u3002\u56e0\u6b64\uff0c\u6bcf\u4e2a\u6eda\u5b50\u90fd\u9700\u8981\u826f\u597d\u7684\u6da6\u6ed1\u3002\u7531\u4e8e\u6cb9\u5b54\u4e0d\u53ef\u80fd\u4e0e\u6bcf\u4e2a\u6eda\u5b50\u90fd\u5bf9\u9f50\uff0c\u6da6\u6ed1\u901a\u9053\u7684\u8bbe\u8ba1\u81f3\u5173\u91cd\u8981\u3002\u5b9e\u9645\u4e0a\uff0c\u8fd9\u79cd\u8054\u8f74\u5668\u7684\u6da6\u6ed1\u6761\u4ef6\u76f8\u5bf9\u8f83\u5dee\u3002<\/li>\n\n\n\n<li><strong>WZL\u7403\u5f62\u94f0\u63a5\u8054\u8f74\u5668\uff1a<\/strong> \u7279\u6b8a\u952e\u4f20\u9012\u626d\u77e9\uff0c\u800c\u7403\u9762\u627f\u53d7\u5f84\u5411\u8f7d\u8377\u3002\u6da6\u6ed1\u7279\u6b8a\u952e\u81f3\u5173\u91cd\u8981\uff0c\u4f46\u7531\u4e8e\u53ea\u6709\u4e24\u4e2a\u952e\uff0c\u56e0\u6b64\u6cb9\u5b54\u53ef\u4ee5\u8bbe\u7f6e\u5728\u5b83\u4eec\u9644\u8fd1\u3002\u7403\u9762\u4e5f\u5fc5\u987b\u6da6\u6ed1\uff0c\u56e0\u4e3a\u5176\u8f83\u5927\u7684\u63a5\u89e6\u9762\u79ef\u5728\u6da6\u6ed1\u4e0d\u8db3\u65f6\u4f1a\u4ea7\u751f\u76f8\u5f53\u5927\u7684\u6469\u64e6\u963b\u529b\u3002\u7403\u9762\u94f0\u94fe\u8868\u9762\u7684\u6cb9\u4fdd\u6301\u6027\u8f83\u5dee\uff0c\u56e0\u6b64\u5176\u6da6\u6ed1\u6761\u4ef6\u4e5f\u4e0d\u7406\u60f3\u3002<\/li>\n\n\n\n<li><strong>\u76f4\u6d41\u51a0\u72b6\u9f7f\u8f6e\u8054\u8f74\u5668\uff1a<\/strong> \u9f7f\u8f6e\u526f\u4f20\u9012\u626d\u77e9\uff0c\u7403\u9762\u627f\u53d7\u5f84\u5411\u8f7d\u8377\u3002\u4e3b\u8981\u7684\u6da6\u6ed1\u533a\u57df\u662f\u7403\u9762\u63a5\u89e6\u533a\u57df\u3002\u5916\u5957\u7b52\u7684\u63a5\u89e6\u9762\u5b9e\u9645\u4e0a\u662f\u5706\u67f1\u9762\uff0c\u800c\u53ea\u6709\u5185\u5957\u7b52\u5177\u6709\u7403\u9762\u63a5\u89e6\u9762\uff1b\u8fd9\u5f62\u6210\u7ebf\u63a5\u89e6\uff0c\u4f7f\u6da6\u6ed1\u6cb9\u80fd\u591f\u4fdd\u6301\u5728\u63a5\u89e6\u9762\u4e4b\u95f4\u3002\u56e0\u6b64\uff0c\u5176\u6da6\u6ed1\u6761\u4ef6\u76f8\u5bf9\u8f83\u597d\u3002<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"2-3-installation-characteristics\">2.3 \u5b89\u88c5\u7279\u70b9<\/h3>\n\n\n\n<p>Because the three overhead crane drum couplings differ in their sensitivity to axis deviation, the coupling type installed on the hoisting mechanism should be identified before installing the drum.
