ZJY Series Axle-mounted Reducer
1. Overview:
ZJY/ZGY/TIT series axle-mounted reducers adopt the installation method directly suspended on the power input shaft of the matching main engine, omitting the connection accessories between them and the installation platform of the decelerator. They are widely applicable to the mechanical transmission of belt conveyor scraper conveyor, bucket elevator and other equipment, and can also be matched with other mainframes with the installation requirements.
The product is manufactured according to ZBY19009-88 standard. The main transmission parts are made of alloy steel. The gear is processed by carbon grinding point. The precision reaches grade 6 (GB10095-88). The product has the advantages of small volume, high carrying capacity, long service life, low noise and high efficiency.
2. Scope of application
The maximum speed of the high-speed end does not exceed 1500 r/mn.
The working environment is warm from 40 C to 45 C.

ZJY axle-mounted gear reducer (JB/T 7007-1993) is also a parallel axle and involute cylindrical gear reducer with zigzag axes. It is mainly used for driving device of belt conveyor and bucket elevator, as well as other types of mechanical equipment. Working conditions: the speed of the high speed shaft of the reducer is not more than 1500r/min, and the working environment temperature is - 40-40 C. When the temperature is lower than 5 C, the lubricating oil should be preheated to more than 10 C before start-up.
Feature description
1. Connection of Reducer and Work Machine
The ZJY reducer is directly mounted on the main axle of the working machine. When the reducer is running, the reaction moment acting on the reducer box body is also mounted on the counter moment bracket of the reducer box body or balanced by other methods. The machine is directly matched and the other end is connected with the fixing bracket.
2. Installation of Reaction Moment Support
Counter-moment brackets should be installed on the side of the reducer facing the machine to reduce the additional bending moment on the axle of the machine. Elastomers such as rubber are used in the sleeve of the connecting end of the reaction moment bracket and the fixed support to prevent flexion and absorb the torque fluctuation.
3. Installation Relation between Reducer and Work Machine
In order to avoid the deflection of the main shaft and the additional force on the bearing of the reducer, the distance between the reducer and the working machine should be as small as possible without affecting the normal working conditions, the value of which is 5-10mm. Inspection and maintenance of speed reducer
L-CKC100~L-CKC220 EP industrial gear oil injected into GB/T5903 should be changed for the first time after 200-300 hours of operation. The quality of oil should be checked regularly in future use. Oil mixed with impurities or deteriorated should be replaced in time.
1、減速器一般采用垂直位置及其前后各20°范圍內(nèi)懸掛安裝，與主機配套使用。
2、減速器輸出軸孔套入主機軸前，應(yīng)在軸和軸孔表面涂上油脂，以減小裝配阻力。切勿采用強行打擊的方式安裝，否則可造成軸承損壞或空心軸端變形。 對采用雙端錐套安裝的減速器，可按如下程序
安裝：
（1）先將內(nèi)側(cè)的空心錐套套入主機主軸；
（2）將減速器推入主機主軸，左端掛在左錐套上；
（3）從右側(cè)裝入右錐套；
（4）依此擰緊左右錐套的緊固螺釘。
3、安裝傳動三角帶。由于減速器體積緊湊，所配置的軸承尺寸較小，為確保軸承正常使用，請注意以下幾點：
（1）盡可能選用高強度窄型三角帶。窄型三角帶可減小帶輪的寬度和外圓尺寸，以及三角帶的張緊拉力，這樣可以使輸入軸帶輪的張緊力作用點位置靠近輸入軸內(nèi)側(cè)，對提高輸入軸軸承的壽命十分有
利。
（2）應(yīng)選用全部金加工的三角帶輪。對有輪輻減輕孔的帶輪，應(yīng)滿足靜平衡的要求。
（3）三角帶應(yīng)緊張適度。一般可用兩個手指下壓三角帶，受壓點下移是否在1-2mm的方法來判別三角帶的緊張程度。由于三角帶在運行一段時間后會因初張力延長而打滑了，該延長量應(yīng)以二次緊張來
彌補。切勿在初裝時過分緊張，給輸入軸軸承增加不應(yīng)有的懸臂拉力。
4、為克服減速器在運行時空心軸軸承摩擦反力矩對減速器箱體的作用，一般采用防扭拉桿來平衡該力矩。防扭拉桿的安裝位置見圖1。防扭拉桿可采用00型"開式鎖具螺旋扣"，見附錄2。由于索口環(huán)頭
內(nèi)孔尺寸不規(guī)范，可用經(jīng)過加工的環(huán)頭更換。環(huán)頭內(nèi)孔與拉桿銷的配合可采用H9/n9。采用小間隙的環(huán)頭配合，可減小減速器的左右晃動。
5、打開減速器箱體中部油塞，使箱體處于垂直位置，從吊環(huán)孔加入N220中級壓齒輪油，油位至下部油塞溢出高度。
6、減速器現(xiàn)空載運轉(zhuǎn)一段時間，檢查是否有異常噪聲、漏油、振動等不正?，F(xiàn)象，如無則可投入負(fù)載運行。
7、減速器首次運轉(zhuǎn)300-600小時后應(yīng)更換潤滑油。此后每運轉(zhuǎn)1500-5000小時更換一次（主要由工作環(huán)境而定），最長不得超過18個月。在換油時應(yīng)同時清洗磁性油塞（安裝在箱體下部）。
8、減速器在運行中出現(xiàn)油溫突然性升高或不正常噪聲時，應(yīng)立即停車檢查。故障排除后，才能繼續(xù)投入工作。
9、當(dāng)單向運轉(zhuǎn)的減速器需反向或雙向運轉(zhuǎn)時，可打開輸入軸對面端蓋，對常接觸式逆止器將星輪用拉板拉出（拉板可按星輪上起吊螺孔位置自制）反裝，即可改向運轉(zhuǎn)；或拆除星輪缺口處的滾子、頂
銷（小規(guī)格的無此零件）、頂簧，實現(xiàn)雙向運轉(zhuǎn)。對非常接觸逆止器，則需要將逆止體拉出反裝，同時把外環(huán)也卸下反裝。
10、空心軸端蓋用于固定減速器軸向位置和拆卸減速器用。用于固定時，用與中心孔徑相配的六角螺栓吊緊主機輸入軸；用于拆卸時，可在兩側(cè)螺紋孔內(nèi)旋入六角螺栓，頂出箱體。
