本系列産品中的(de)規格和(hé)傳動比爲現有用(yòng)戶的(de)常用(yòng)數據。用(yòng)戶在選用(yòng)時(shí)，可(kě)将螺杆的(de)實際傳動扭矩與表(2)所列許用(yòng)輸出扭矩相比較(表列扭矩已計入工況系數和(hé)安全系數，可(kě)1:1 直選)，以輸出扭矩爲準選型。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(yòng)戶提出具體技術參數.向我廠咨詢再确定選型。
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、适用(yòng)條件Service condition
1。減速器高(gāo)速軸轉速不大(dà)于1500r/min;
1. Rotate speed of decelerator high-speed shaft no more than 1500r/min;
2.工作環境溫度爲0-35'C。當溫度範圍超出本規定時(shí)，可(kě)按用(yòng)戶要求，另行配置加熱(rè)或冷(lěng)卻裝置。
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、減速器代号和(hé)标志Decelerator code and earmark
在減速器代号中，包括型号，輸出級中心距、公稱傳動比、裝配型式。
Decelerator code is composed of type, output stage center distance;nominal drive ratio and assemblage mode.
4.當取軸承負荷系數f=1.5時(shí)。按表列許用(yòng)軸向推力和(hé)輸出軸給定轉速計算(suàn)，推力軸承的(de)理(lǐ)論計算(suàn)壽命，除133. 146 兩型爲1.2萬小時(shí)左右，其各型皆在2.5萬小時(shí)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(yòng)戶按表列數據作初步選型。在訂貨時(shí)，我廠将對(duì)每一例選型作詳細校核，以提高(gāo)選用(yòng)的(de)可(kě)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、潤滑與冷(lěng)卻、加熱(rè)Lubrication ,cooling and heating
齒輪和(hé)軸承皆用(yòng)油池潤滑和(hé)”飛(fēi)濺潤滑。ZLYJ280 及以上規格的(de)承除飛(fēi)濺潤滑而外，還(hái)增加了(le)油泵潤滑系統強制循環供油潤滑。
潤滑油牌号爲中極壓齒油N150或其它粘度相似的(de)優質齒輪油。
當環境溫度低于0C時(shí)，需在油池中增加電熱(rè)管，對(duì)潤滑油進行了(le)預熱(rè)
當環境溫度高(gāo)于35"C時(shí)，制造廠應按手用(yòng)戶提供的(de)溫度值進行熱(rè)平計算(suàn)，以确定是否增加冷(lěng)卻裝置。
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.
強制潤滑油路的(de)示意圖見圖3。See Figure 3 for sketch map of forcible lubrication oilway
