Zlyj330 Extruder Machine Gearbox

Product Description>IntroductionZLYJ series Reduction Gearbox (speed reducer) is a transmission part for most single screw extrusion line, wihch also possesses high precision hard gear surface and thrust block designed. Designed with standard ZBJ19009-88, it combines well with most of machines from different suppliers. Also the gear and axis parts are made of high strength alloy steel with surface hardness HRC54~62. In the front end of hollow input axis there is large specification thrust bearing that will bear axial thrust force while the screw is working  >Applied Circumstance1. All kind of extrusion & blowing machinery2. High speed shaft rotation Speed Major Technical Index1. Output Speed: 16-100 RPM2. Output Torque: Max.4300 Nm3. Motor Power: 5.5-200 Kw  >Selection of Gearbox1. Select speed ratio e.g. input speed n1=1000rpm, output speed n2=70rpm, ratio i=n1/n2=14.28, should select ratio 14 2. Select model type according to input power e.g. input power P=26kw, after checking form, 29kw>26kw, most ecomonic should be ZLYJ200 3. Select assemble type as per actual use, select horizontal or vertical type 4. Calculate axial thrust Fa=π*Ds²*Ps/(4*1000) e.g. Screw diameter Ds=75mm, Screw pressure Ps=26MPa Fa=π*Ds²*Ps/(4*1000)=114.8kN 187kN>114.8kN, ZLYJ200 can bear the axial thrust and economic to select 5. Confirm connection size 6. Confirm cooling type Parameters ConcernedRecommended Products   EXTRUSION SCREW BARREL         INJECTION SCREW BARREL         TWIN SCREW BARREL/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
