塑料挤出机专用减速机
ZLYJ系列高强度硬齿面减速机
Special decelerator for Plastic Extruder
Series ZLYJ Decelerator with High Strength and Hard Tooth Surface
一、概述Brief
ZLYJ系列减速器是为塑料螺杆挤出机配套设计的高精度硬齿面带推力座的传动部件。产品设计采用了ZBJ19009-88所规定的各项技术规范。其特点是齿轮和轴类零件采用了高强度合金钢材质。齿轮经渗碳，淬火，磨齿工艺加工。齿轮精度为GB10095-88. 6级。齿面硬度HRC54-62.在空心输出轴前端配置有超规格的推力轴承，承受螺杆的工作后座力。轴承和油封等主要标准件皆采用国内优质产品，也可按用户需要，配装进口产品。整机具有体积小。承载能力高，传动平稳.噪声低，效率高等特点。产品性能已达到国际先进水平，可替代同类进口产品使用。
本系列产品中的规格和传动比为现有用户的常用数据。用户在选用时，可将螺杆的实际传动扭矩与表(2)所列许用输出扭矩相比较(表列扭矩已计入工况系数和安全系数，可1:1 直选)，以输出扭矩为准选型。若需与橡胶挤出机配套，因橡胶挤出机冲击力较塑料强，请用户提出具体技术参数.向我厂咨询再确定选型。
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、适用条件Service condition
1。减速器高速轴转速不大于1500r/min;
1. Rotate speed of decelerator high-speed shaft no more than 1500r/min;
2.工作环境温度为0-35'C。当温度范围超出本规定时，可按用户要求，另行配置加热或冷却装置。
2. Ambient service temperature is 0-35'C. If the temperature is beyond this range, the lubricating heating or cooling device is supplied as required by user.
三、减速器代号和标志Decelerator code and earmark
在减速器代号中，包括型号，输出级中心距、公称传动比、装配型式。
Decelerator code is composed of type, output stage center distance;nominal drive ratio and assemblage mode.
4.当取轴承负荷系数f=1.5时。按表列许用轴向推力和输出轴给定转速计算，推力轴承的理论计算寿命，除133. 146 两型为1.2万小时左右，其各型皆在2.5万小时左右。
4.f bearing load factor is f.=1.5, calculation is made according to allowable axial thrust and output shaft given rotate speed listed in the table theoretical calculating life of thrust bearing is about 12.000 hours for type 133 or 146, and about 25,000 hours for all of the rest types.
5.用户按表列数据作初步选型。在订货时，我厂将对每一例选型作详细校核，以提高选用的可靠性。
5.User is to make preliminary selection according to the listed data .when products are ordered,we will make detail and careful verification for each of user’s selection to enhance the applicability of the selection.
六、润滑与冷却、加热Lubrication ,cooling and heating
齿轮和轴承皆用油池润滑和”飞溅润滑。ZLYJ280 及以上规格的承除飞溅润滑而外，还增加了油泵润滑系统强制循环供油润滑。
润滑油牌号为中极压齿油N150或其它粘度相似的优质齿轮油。
当环境温度低于0C时，需在油池中增加电热管，对润滑油进行了预热
当环境温度高于35"C时，制造厂应按手用户提供的温度值进行热平计算，以确定是否增加冷却装置。
Oil sump submergence and splash lubrication are used for gear wheel and bearing.for bearing type ZLYJ280 and aborve ,oil pump lubrication system is added for forcible circulation feed lubrication,except for splash lubrication.
Lubricant brand is mild extreme, pressure gear; lubricant N150 or other quality gear lubricant with similar viscosity.
If ambient temperature is <0'C ,electrical heating pipe should be mounted in oil sump to preheat lubricant oil.
If ambient temperature is >35'C，the manufacturer should make proper calculation in terms of heat balancing based on the temperature data supplied by user and decide whether a cooling device is needed.
强制润滑油路的示意图见图3。See Figure 3 for sketch map of forcible lubrication oilway
