2)the host serial number or the date of delivery(shown on the host machine nameplate)

3)detailed failure phenomena, photographs, sound recordings etc.

4)customer units and contact information

 

5.易损件,备品和备件 expendables and spare parts

齿轮箱的易损件主要包括油封和轴承,他们是齿轮箱运行中必不可少却又容易损坏的部件,通常情况下使用者要有一定量的备品备件,以防不时之需。

The damageable parts of gear unit include oil seal and rolling bearing. They are absolutely necessary, but they are furthest damageable parts during the process of the gear unit's running. Customers should deposit some spare part in order to need when these parts are abrupt shattered.

5.1轴承bearing

对轴承的保养很重要,每年齿轮箱大修或者新设备开始运行时,都要对轴承进行清洗,随时检测油品清洁度或更换润滑油。虽然轴承材料都是经过特殊的热处理,可以长时间在高温下运行,但建议轴承最好在80°C以下运行,最高不超过100°C。

It is very important for bearing‘s maintaining. Consumer should rinse bearings when the gear unit is annually heavy repaired or new equipment begin running, and inspect cleanliness of lubrication or replace lubrication. Although the bearing's material is especial heat treatment, run under the high temperature for a long time. We suggest bearings had better run at below 80°C and no more highest than 100°C

5.2油封oil seal

油封的材料通常为丁睛橡胶(NBR)和氟橡胶(FPM),在实际使用时要特别注意,使用和处理不当可能会造成人员伤害。

齿轮箱运行一段时间后,油封会出现损耗或老化,为了提高设备运行效率和维修时间,通常需要准备一些备品备件,建议按运行6个月时间准备高速轴油封备品,12个月时间准备输出轴油封备品。

The material of oil seal usually is nitrile rubber and fluoro rubber. That oil seal is improperly used and disposed will hurt personnel, so handlers must especially notice. the gear unit running after a period of time, loss or aging of oil seal can appear, in order to improve the efficiency of equipment operation and maintenance time, usually need to prepare some spare parts, recommendations according to run 6 months to prepare for the high speed shaft seal spare parts, 12 months to prepare the output shaft oil seal spare parts.

 

6.常见故障及应急方法 common failures and handing

6.1 齿轮箱有异常响声与抖动 gearbox abnormal noise and vibration

6.1.1齿轮箱在正常使用过程中,声音突然增大或齿轮箱抖动明显增大,却不能减少,应立即停机检查。

1)齿轮啮合部分有损伤——检查啮合齿轮,可能需要更换损伤部件。

2)轴承间隙增大——调整轴承间隙

3)轴承损坏——更换损坏轴承

4)齿轮箱地脚孔螺栓有松动——锁紧地脚螺栓并配用螺纹密封胶

5)电机地脚螺栓有松动,齿轮箱与电机连接的同心度超出规定范围——重新校调同心度至规定范围

6)齿轮箱过载——降低负荷至额定功率范围

7)联轴器是否对中,是否有损坏——重新校对并符合要求,或更换联轴器

8)润滑系统是否正常——调节喷油量及喷油位置

Gearbox in normal use, the sound suddenly increase or gearbox vibration significantly increased, however cannot be reduced. At this time, the gearbox should be immediately stopped and need to be checked.

1)there is damage in the point where two gears mesh——examine the teeth, you may need to replace the damaged parts.

2)bearing clearance increased——to adjust the bearing clearance.

3)bearing damage——replace damaged bearings

4)the screw of gearbox foot hole is loosed——tighten the anchor bolts with thread sealant

5)motor foot hole screw are loosethe gearbox and motor connections concentricity is out of range——re-calibrated to the required range of concentricity.

6)whether the gearbox is overload——decrease the load into the nominated range

7)alignment of couplingwhether there are damages in the coupling——readjust coupling or replace the oil seal.

8)whether the lubrication system is functioning normally——adjust the oil spray quantity and nozzle orientation.

6.2齿轮箱温度异常升高gearbox abnormal temperature rise

6.2.1齿轮箱比较理想的工作温度为40~60°C,如果齿轮箱温升超过35°C,或者润滑油工作温度超过65°C时,建议停机检查。一般需检查以下情况:

1)检查油位,观看油镜,油尺或者液位计是否按说明书要求加油,油位过高过低都会引起油温过高。

2)齿轮油老化,污染——确定上一次更换齿轮油的时间,重新更换润滑油

3)带外冷却器的齿轮箱——冷却水流量太小,检查冷却水流动是否通畅

4)冷却水温度太高——降低冷却水温度

5)经过冷却器的油量太小——过滤器杂质过多堵塞滤网,需清理过滤器滤网;也可能是油泵损坏,需要换油泵

6)轴承损坏——更换轴承

Gearbox ideal operating temperature is 40~60°Cif the gearbox temperature rise exceeds 35°Cor the oil temperature exceeds 65°C,recommended shut down and check the gearbox. Ordinarily the below steps need to followed:

1)check the oil level, watch oil immersion, oil dipstick or gauge. To see whether charge the oil according the requirements. The oil level is too high or too low will cause the high oil temperature.

2)gear oil aging or polluted——to confirm the time of the last oil change or replace the lubrication oil.

3)gearbox with a cooler——cooling water flow is too small. Check the cooling water flow is unobstructed.

4)high temperature of cooling water——lower the temperature of cooling water

5)gear oil flow through the cooler is too small——probably too many impurities clog the filter strainer, need to clean the filter screen, or the pump may be damaged and need to replace.

6)The bearing is damage——replace the bearing

6.3 漏油 leakage

6.3.1检查漏油位置,找出漏油点,如果是油封渗漏油:

1)油封唇口是否损坏或油封是否老化——更换油封

2)回油孔是否通畅——清洁回油孔,检查润滑油质量

3)检查装油封处轴颈光洁度,是否有划痕——打磨并用金相砂纸抛光,如严重更换备件

4)进油量是否过大——调节油量

5)油封与轴颈的同轴度是否符合要求——重新加工端盖上装油封的孔

如果是油路管接头处漏油,一般是卡套帽松动,用扳手拧紧即可

1)whether the tip of oil seal has been damaged or the seal has aged——replace the oil seal

2)whether the oil return hole is clean——clean the oil return hole and check the quality of the lubrication oil.

3)roughness if the shaft journal under oil seal, whether there is scratch——grind and poolish using abrasive paperif the damage or scratch is seriousreplace the shaft with spare parts.

4)whether the input oil quantity is too large——adjust the oil quantity

5)coaxiality between the oil seal and the shaft journal——remachine the seal hole of oil seal in the cover.
