一、概述Brief

ZLYJ系列減速器是為塑料螺桿擠出機(jī)配套設(shè)計(jì)的高精度硬齒面帶推力座的傳動(dòng)部件。產(chǎn)品設(shè)計(jì)采用了ZBJ19009-88所規(guī)定的各項(xiàng)技術(shù)規(guī)范。其特點(diǎn)是齒輪和軸類零件采用了高強(qiáng)度合金鋼材質(zhì)。齒輪經(jīng)滲碳，淬火，磨齒工藝加工。齒輪精度為GB10095-88. 6級(jí)。齒面硬度HRC54-62.在空心輸出軸前端配置有超規(guī)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(biāo)準(zhǔn)件皆采用國(guó)內(nèi)優(yōu)質(zhì)產(chǎn)品，也可按用戶需要，配裝進(jìn)口產(chǎn)品。整機(jī)具有體積小。承載能力高，傳動(dòng)平穩(wěn).噪聲低，效率高等特點(diǎn)。產(chǎn)品性能已達(dá)到國(guó)際先進(jìn)水平，可替代同類進(jìn)口產(chǎn)品使用。

本系列產(chǎn)品中的規(guī)格和傳動(dòng)比為現(xiàn)有用戶的常用數(shù)據(jù)。用戶在選用時(shí)，可將螺桿的實(shí)際傳動(dòng)扭矩與表(2)所列許用輸出扭矩相比較(表列扭矩已計(jì)入工況系數(shù)和安全系數(shù)，可1:1 直選)，以輸出扭矩為準(zhǔn)選型。若需與橡膠擠出機(jī)配套，因橡膠擠出機(jī)沖擊力較塑料強(qiáng)，請(qǐng)用戶提出具體技術(shù)參數(shù).向我廠咨詢?cè)俅_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

1。減速器高速軸轉(zhuǎn)速不大于1500r/min;

1. Rotate speed of decelerator high-speed shaft no more than 1500r/min;

2.工作環(huán)境溫度為0-35'C。當(dāng)溫度范圍超出本規(guī)定時(shí)，可按用戶要求，另行配置加熱或冷卻裝置。

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、減速器代號(hào)和標(biāo)志Decelerator code and earmark

在減速器代號(hào)中，包括型號(hào)，輸出級(jí)中心距、公稱傳動(dòng)比、裝配型式。

Decelerator code is composed of type, output stage center distance;nominal drive ratio and assemblage mode.

4.當(dāng)取軸承負(fù)荷系數(shù)f=1.5時(shí)。按表列許用軸向推力和輸出軸給定轉(zhuǎn)速計(jì)算，推力軸承的理論計(jì)算壽命，除133. 146 兩型為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.用戶按表列數(shù)據(jù)作初步選型。在訂貨時(shí)，我廠將對(duì)每一例選型作詳細(xì)校核，以提高選用的可靠性。

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、潤(rùn)滑與冷卻、加熱Lubrication ,cooling and heating

齒輪和軸承皆用油池潤(rùn)滑和”飛濺潤(rùn)滑。ZLYJ280 及以上規(guī)格的承除飛濺潤(rùn)滑而外，還增加了油泵潤(rùn)滑系統(tǒng)強(qiáng)制循環(huán)供油潤(rùn)滑。

潤(rùn)滑油牌號(hào)為中極壓齒油N150或其它粘度相似的優(yōu)質(zhì)齒輪油。

當(dāng)環(huán)境溫度低于0C時(shí)，需在油池中增加電熱管，對(duì)潤(rùn)滑油進(jìn)行了預(yù)熱

當(dāng)環(huán)境溫度高于35"C時(shí)，制造廠應(yīng)按手用戶提供的溫度值進(jìn)行熱平計(jì)算，以確定是否增加冷卻裝置。

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.
