ZLYJ Series Gearboxes for Single Screw Extruder are a kind of special gearboxes researched and developed byimportind the  advanced tchnologoyo of the hard tet-surfa in the world. For recent ten years, they are widely usedintop and middle grade plastic, rubber and chemical fiber extruders, sell well in the county and are exported abroad.With ahigher reputation in the industry, it has features as flows:
1. The whole machine looks beautiful and liberal, and can be used both vertically and horizontally. It can suit multiplerequirement of assembling.
2. The gear data and box structure are optimally designed by the computer. The gears are made of top grade low carbon alloy steel with Grade 6 precision of teeth atter carbon penetrating, quench and teeth grinding. The hardnessof the teeth surface is 54.62 HRC. The gear pair has stable running, low noisy and has high driving ficiency.
3. The assembling connector  can be easily connected with screw rod of the machine barrel.

4. The bearing structure of the output shat has a unique style, which can efetively prolong service ife of the bearings.

5. All standard parts such as bearing, oil seal, lubricant oil pump etc. are all top quality products selected from domestic famous manufacturers. They can be also selected trom impoted products as per requirement of customer.

1.This eries produt can be used n educing dving of sngne scew rod etudter with he screw rod dameler of 30.250mm.

2.The input speed of the gearboxer is normally not larger than 1500 rpm.
3.The dvwing alio 1 bewen 6.3 and 20, adghat in Be table can be slelede rfentiat The drwing naio can be also adjusted as per requirement of customer.
4.The temperature in work enionmentis-10℃- 45℃should be preheated before starting. When emperature is ower than0℃ the lbriant oil should be preheated before starting.

·安装使用和维护 Assebling,Aplication and Maintenance

1、起吊齿轮箱时，应使用吊环螺钉。
2、齿轮箱运输、存放时应注意防潮。到货后如半年内不安装，应对外露的加工面重新涂防锈油。
3、齿轮箱安装的底座要平整,并且有强度和刚性,在地脚螺栓均匀紧固的情况下，应确定输出轴中的螺杆能无卡滞地均匀回转。联轴器的安装误差应不超过其允许的偏差值,以免引起附加力,缩短轴承寿命。
4、齿轮箱在交货前均经过严格的试运转检验，各项指际符合要求，交货后可以直接投入使用。使用前应注入中压齿轮油N220至油标上限(采用循环油润滑用N150).如齿轮箱附带列管式油冷却器则须在加油后，空车运转一段时间后，再次加油至油标上限。
5、带有电机油泵的齿轮箱，在加载前，应先开启电机油泵，空车运转一段时间，以利各润滑点的充分润滑。6、齿轮箱在运行300小时后换油，以后每运行3000~4000小时换油一次，每次换油的间隔时间不应超过18个月。换油时应先清洗箱体、滤油器、空气滤清器、放油螺塞。
1. When liting the gearbox, the ring screw should be used.
2. Take care to prevent moisture when the gearbox is in transportation or storage. If do not assemble in half a year after it is arrived, the exposure surface should be coated with antrust oil.
3. The base to assemble the gearbox should be plain with enough strength and igidit. Under circumstance the anchor bolts are evenly tightened, it should ensure that the screw rod inserted into the output shaft should be rotated freely without blockage. The assembling error of the coupler should do not excess its alwedtolerance so as to avoid from added force and to prolong the life of the bearings.
4. The gearbox should pass through stict test rnning nspecton beiore they are dlivere Only a index arein acording to the rquirement, can they be put nto use drety ater divery. Belore apicainn it should befled with md-xteme pessre gear oil N220 up to the upper imit of the oil mank (N150 I iculation pump ubrication is used), If the reducer has pipe style oi cor then run the reducer under no-load for a shortperiodl of time ater oil is flede, then fll oil again up to the upper limit of the oil mark.
5. For the gearbox with motor oil pump,before adding load, it should switch on the oil pump of the motor to runthe geabox under noload for a shont period of tine so as o fcite ull lbricaionn of al ubicen ponis.
6. Replce oil when he geatbox is ialyl uning for 3000 hours, and change oil once for every 30 4000; tereter The maximum ineval between oil replacements should be no longer than 18 months.running hours When eplacingn, fist cleanbox body,oil fter, air fiter and oil discharge screw plug.
