减速机一般用于低转速大扭矩的传动设备，把电动机、内燃机或其它高速运转的动力通过减速机的输入轴上的齿数少的齿轮啮合输出轴上的大齿轮来达到减速的目的，普通的减速机也会有几对相同原理齿轮达到理想的减速，大小齿轮的齿数之比，就是传动比。Reducerisgenerallyusedindrivingequipmentoflowspeedhightorque,largegeargearoutputshaftpowermotor,internalcombustionengineorotherhighspeedrunningthroughthereducerinputshaftlessnumberofteethonthereducertoachievethepureofgeneralreducerwillh***eseveralpairsofthesameprincipletoachievetheidealeffectofgearreducer.Thesizeofthenumberofteethofthegearratio,thetran***issionratiois.我国减速机行业发展历史已有近40年，在国民经济及工业的各个领域，减速机产品都有着广泛的应用。食品轻工、电力机械、建筑机械、冶金机械、水泥机械、环保机械、电子电器、筑路机械、水利机械、化工机械、矿山机械、输送机械、建材机械、橡胶机械、石油机械等行业领域对减速机产品都有旺盛的需求。减速机动力源运转速度根据在不同转速条件下对减速机的试验表明，随着减速机输入转速的增加，噪声也将增大。Chinasspeedreducerindustryhasbeendevelopingfornearly40years.Inallfieldsofnationaleconomyandnationaldefenseindustry,thereducerhasawiderangeofapplicati.Foodindustry,electricalmachinery,ctructionmachinery,metallurgicalmachinery,cementmachinery,environmentalprotectionmachinery,electronicappliances,ctructionmachinery,hydraulicmachinery,chemicalmachinery,miningmachinery,transportationmachinery,buildingmaterialsmachinery,rubbermachinery,petroleummachineryandotherindustriesonthereducerproductsh***estrongdemand.反力矩支架的安装：反力矩支架应安装在减速机朝向的工作机的那一侧，以减小附加在工作机轴上的弯矩。反力矩支架与固定支承联接端的轴套使用橡胶等弹性体，以防止发生挠曲并吸收所产生的转矩波动.Reversetorquesupportinstallation:thereversetorquebracketshouldbeinstalledonthesideoftheworkingmachinefacingthereducerinordertoreducetheadditionalbendingmomentontheworkingshaft.Therubberandotherelastomersareusedintheshaftsleeveofthereversetorquebracketandthefixedsupportjunctiontopreventtheflexureandabsorptionofthetorqueripple.通常齿轮减速机已广泛应用于冶金、矿山、起重、运输、水泥、建筑、化工、纺织、印染、制药、等领域。但在这种齿轮减速机的使用有一定的限制,所以,让我们了解下使用时需要注意什么。1、高速旋转不超过1500r/min。齿轮减速器。2、齿轮圆周速度不超过20m/s。Usuallygearreducerhasbeenwidelyusedinmetallurgy,mining,lifting,transportation,cement,ctruction,chemical,textile,printinganddyeing,pharmaceutical,andotherfields.Buttherearesomerestrictiontheuseofthisgearreducer,soletusknowwhattopayattentiontowhenusingit.1.Thehighspeedrotationdoesnotexceed1500R/min.Gearreducer.2,thecircumferentialspeedofthegearisnotmorethan20m/S.)
