Shanghai Daoqin Plastics Co., Ltd.

gears is machine force and 运动 一 types main/primary 形式. gears industrial is machine industrial in technology most 密集, most industry. gears industrial main/primary 包括三部 separation:车辆 gears manufacturing, industrial gears manufacturing and gears manufacturing. plastics gears formed is injection molding processing large trend.

    2009 year, China gears, and 驱动部 parts manufacturing 业经受住 国际金 melt machine effect/influence, industry maintain stability growth, although increase speed relatively upper year large lower slip, in 美, day and other 发达国家受金 melt machine effect/influence industry sales decrease/reduce ring lower, China gears, and 驱动部 parts manufacturing 业 平稳 growth still to full 球瞩目, China already formed is full gears and other equipment production large 国.

    gears, and 驱动部 parts is machine equipment in most basic parts 之一, 各国都 has amount more enterprise production gears parts. in outer, 传动驱动 parts production 均以专业化 is 主, generally enterprise is in, small type, in 数十至数百人; has very more enterprise is full property, in world has production, sales and 服务网点; another 一 传动驱动 parts company is large group company separation. China in already world 传动驱动零部 parts production large 国之列, main/primary in low product is 主. currently, 传动驱动零部 parts full market most large several or is Germany, 北美, Japan, Korea, and Italy, France and other Europe 国家以 and China.

    我国国民经济 fast speed development and outer 发达国家 industry structure adjustment, to gears, and 驱动部 parts industry belt/tape development machine 遇, day growth inner outer market demand, belt/tape 动 整 industry speed development, make industry production capacity fast speed increase, production amount large degree improve/increase.

    gears mold application scope large can separation is 三 方面: plastics gears use mold, powder 末冶金 gears use mold and 精锻锥 gears use mold. its in, plastics gears use mold demand amount comparison large. gears main/primary use has 两, is 传递运动, is 传递动 force. currently inner plastics gears main/primary by use 传递运动, USA in in 传递动 force selection upper, 也越 越 more using/adopting plastics gears. this is is plastics gears has very more advantages, ratio 如传动噪声 low, can 够吸振, lubricated and other and other, but also plastics gears can mold opening processing, production efficiency high. 应该说, plastics gears in gears industry application 会越 越 more, this is world property trend.

    currently in low gears mold in inner can production, high gears mold more Imported. inner 专门做 gears mold factory more, large gears 厂自己做 gears mold, gears 厂往往设一 工段 or workshop this as. in 精锻锥 gears 方面, 株齿, 江苏飞船, 太平洋精锻 and other enterprise manufacturing gears mold in gears mold industry is comparison good, its 精锻锥 gears quality relatively high. in plastics gears 方面, 总体 说, plastics gears and its mold main/primary distribution in 两 区域, is 浙江宁波, this has 340 more plastics gears 厂, is most large plastics gears mold production 基; 另一 就 is deep 圳宝安, 以港资 enterprise is 主, product degree relatively high, main/primary use outer 销.

    纵观我国 gears mold current situation, can 谓喜忧参 semi. is gears mold production already has 一定基础, plastics gears development large trend to gears mold belt/tape more large market 空间; is inner production gears mold water and world water also has 一段距离, but also in gears industry especially is plastics gears industry large development trend lower, inner for market reaction 不够敏锐, sleeve/set research difficult upper market demand.

    upper, gears plant/unit positive small type 化, high speed 化, standards direction development.特殊 gears application, gears plant/unit development, low 振动, low gears plant/unit made is gears design 方面 一 features. is to gears plant/unit small type 化目, can improve/increase has 渐开线 gears 承载推 force. 各国普遍 using/adopting hard technology, improve/increase hardness shrink small plant/unit dimensions; can application 以圆弧 gears is table/sheet 特殊齿形. method combined as made 舰载直 rise machine 主传动 system using/adopting gears rear, make decrease speed device high degree large is reduce. shipbuilding force in speed machine trend, in large type upper using/adopting large rate gears plant/unit has formed 效; in 冶金, 矿山, water 泥一轧 machine and other large type plant/unit in, gears its small, property good, efficiency high advantages application 愈 愈 more.

gears manufacturing process development very large degree upper performance in degree and other grade and production efficiency improve/increase. 自七十 year various gears manufacturing degree, improve/increase grade left right, has 甚至2～3 grade. generally low speed gears degree 由 8～9 grade improve/increase to 7～8 grade. machine gears 由6～8 grade improve/increase to 4～6 grade.轧 machine gears 由7～8 grade improve/increase to 5～6 grade. for/regarding 模数不 large in small specifications gears, due to high property can machine development, add upper tool material improvement, efficiency has significantly improve/increase. using/adopting more 头滚刀, can to speed degree is 90m/s. use ultra- hard processing 模数3 left right 调质钢 gears, degree can 达200m／s, improve/increase efficiency, need to machine tool 往复运动 machine 构 限 made. most in development using/adopting tool 卸载, use pressure bearings, reinforcement and rigid property and other new structure rear, efficiency has obvious improve/increase. new type machine 冲程数 can to 2000次／ separation. gears use development trend; is 含Cr, Ni, Mo low alloy 钢; is 硼钢; is carbon nitrogen use 钢; is easy 切削钢. due to 我国缺乏Ni, Cr, commonly used 20CrMnTi渗 carbon or use add dilute 土钢. heavy type machine commonly used 18CrMnNiMo渗 carbon or in carbon alloy 钢. machine industry use 40Cr, 38CrMoAl and other and high speed gears use 25Cr2MoV钢进行 nitrogen 化.

    信息化 trend 方面:

    utilizing machine can for various can can design 方实进行计算, analysis and comparison, through excellent 选, relatively is 理想 结果. in analysis 齿面接触区, combined and versus for speed degree in, for elastic lubricated 计算以 and parameters and other 方面编 made 程序. also has, in gears 修形计算 and gears can force 计算方面都编 has 程序. already made GB3480-83渐开线圆柱 gears can force standards soft parts. production application. in gears processing 方面, can utilizing machine control 整 切齿 process. make manufacturing quality stability can 靠. currently, inner in research application micro machine for 弧齿锥 gears adjustment 卡进行计算, can for processing and adjustment, make 齿面接触达 to comparison 理想 位置, large large improve/increase 工效. in addition, according to principle, application micro machine for ring 面蜗杆螺旋齿面进行抛 material 线修形, already used for production. although this 方面 工 as in inner also 处于起步 stage/phase, it for improve/increase gears manufacturing quality and technology water tool has important 意义.

    mold industry expert 罗百辉认 is, made gears mold standards has 效途径应考虑 industry between combined as, industry 协会应该 standards 建立, 统一起. remove large 连理工, 华南理工 and other large in research gears mold outer, already has research in this as. in gears industry and large research machine force amount, process 装备, plastics inner in deformation and other 方面 集 formed research and combined as, is related and currently need 做 工 as. formed 立“ small gears as 委员会”就 is is in discussion solution small gears production in in issues. 如今, world upper most most gears mold standards USA, China gears mold 应该借鉴 USA standards, according to development need, 逐步建立起自己 industry standards and standards. specific 说, is need 一 做 relatively good enterprise 厂标进行 improves, combined outer standards, formed industry standards. this through standards specification market, will can relatively good promote industry development.

    from industry 讲, gears mold very small, but also 处于自发状态, related 专业协会 formed positive is is this type of 状况. formed 立协会仅仅 is 第一步, lower need mold industry expert 罗百辉认 is, made gears mold standards has 效途径应考虑 industry between combined as, industry 协会应该 standards 建立, 统一起. remove large 连理工, 华南理工 and other large in research gears mold outer, already has research in this as. in gears industry and large research machine force amount, process 装备, plastics inner in deformation and other 方面 集 formed research and combined as, is related and currently need 做 工 as. formed 立“ small gears as 委员会”就 is is in discussion solution small gears production in in issues. 如今, world upper most most gears mold standards USA, China gears mold 应该借鉴 USA standards, according to development need, 逐步建立起自己 industry standards and standards. specific 说, is need 一 做 relatively good enterprise 厂标进行 improves, combined outer standards, formed industry standards. this through standards specification market, will can relatively good promote industry development.
