塑料擠出機專用減速機
ZLYJ系列高強度硬齒面減速機
Special decelerator for Plastic Extruder
Series ZLYJ Decelerator with High Strength and Hard Tooth Surface
一、概述Brief
ZLYJ系列減速器是為塑料螺桿擠出機配套設計的高精度硬齒面帶推力座的傳動部件。產品設計采用了ZBJ19009-88所規定的各項技術規范。其特點是齒輪和軸類零件采用了高強度合金鋼材質。齒輪經滲碳，淬火，磨齒工藝加工。齒輪精度為GB10095-88. 6級。齒面硬度HRC54-62.在空心輸出軸前端配置有超規格的推力軸承，承受螺桿的工作后座力。軸承和油封等主要標準件皆采用國內優質產品，也可按用戶需要，配裝進口產品。整機具有體積小。承載能力高，傳動平穩.噪聲低，效率高等特點。產品性能已達到國際先進水平，可替代同類進口產品使用。
本系列產品中的規格和傳動比為現有用戶的常用數據。用戶在選用時，可將螺桿的實際傳動扭矩與表(2)所列許用輸出扭矩相比較(表列扭矩已計入工況系數和安全系數，可1:1 直選)，以輸出扭矩為準選型。若需與橡膠擠出機配套，因橡膠擠出機沖擊力較塑料強，請用戶提出具體技術參數.向我廠咨詢再確定選型。
Series ZLY Jdecelerator is a drive with high- precision and hard tooth surface and thrust bearing designed to match with screw extruder.It is designed according to the specifications in code ZBJ19009 88,leatured with high- strength alloy steels for gear wheel and shaft parts. The gear is treated with carburation,quenching and gear grinding. Gear wheel precision is GB10095-88. class 6.Tooth surface hardness is HRC54-62 A thrust bearing with over- specication is mounted on the front end of the hollow output shaft to carry back blow of screw Domestic quality products are selected for the standard parts such as bearing and oil seal that may also use imported products as required by customer.the whole unit is compacthas high carry capacity,provide stable drive with low noise and high efflciency.the performance of this product is upto the advanced level and a good substiute for imported products of the same kind.
The specifications and drive ratio for these series products is based on the common data currently used by users. To select the desirable productuser may compare the actual screw drive torque with the llowed output torque listed in table 2(The listed torque has llowed for work status factor safety factor and may be selected as 1:1),and use output torque as standard selection.If rubber estruder is needed for the matching,user is required to present detail specifications and consult with us before selection due to the fact that impact of rubber extruder is higher than that of plastic ones.
二、適用條件Service condition
