The vertical mill’s axial bearing is supported by12fan-shaped tilting tile thrust bearing.The two degrees of freedom make internal gear ring and three planetary wheels bear force evenly.The inner gear ring is rigidly fixed on the box body,which, designed into cylinder housing shape,provides an ideal support form for the axial thrust bearing.Besides,the inside and outside walls of cylinder casing are configured with symmetrical reinforcement,thus the body has very good rigidity.The0utput shaft and planet carrier become integrated,making the instructor simple and reasonable.The cone gear adopts Klingelnberg style spiral gear.The parallel shaft gear pair, the sun wheel,and the planet wheel are involute straight tooth.These gears adopt high strength carburized steel,witch,after carburized gear-grinding,are of high precision.All the supporting bearings of the speed reducer gearbox are rolling bearings. The axial thrust bearings are tilting tile thrust bearings.Consisting of several piece of fan bearing shell,they bear the axial thrust of vertical grinding mill.During operation, the bearing bushing is always soaked in the oil tank and constantly offered with fresh lubrication oil through the ring nozzle.So the oil tank always maintains a certain level.Lubricating oil system uses independent stations.And there is oil pressure,oil temperature automatic protection system,making the operation of the whole equipment safe and reliable.Ⅱ.Performance Parameter1.Operational EnvironmentAmbient

people or the machine.Do not remove the nameplate.2.Inspection requirementsAs for the driving device and the reducer,you should check the following items.If there are any problems,please contact our representatives,our own store or office which is nearest to you.(1)Whether what is written on the nameplate is the same as what you ordered.(2)Whether there is any damage in transit.(3)Whether the bolts and nuts becomes flexible.Ⅳ.Lifting、Carriage and Preservation1．Lifting·Please do not stand under the goods to prevent from the safe accident when lifting.·Please pay attention to the lifting position and lift as shown in the illustration lightly.·Pay attention to the risk of falling and reversion when e lifting bolts and lifting hole to lift the actuating unit or gear box.But after they are installed in the equipment,so not use lifting bolts or lifting hole to lift the whole equipment.Because falling,inversion or lifting bolts and holes’damage will lead injury or equipment damaged.·Weight of the driving device and the reducer shall be confirmed according to the nameplate,case,outside view and the sample before lifting.And if it is beyond the rated weight,the lifting shall be not allowed to prevent from the accident.Notice：Lifting directly by the output flange is definitely not allowed2．Carriage·Lubricating oil in the gears box shallbe eliminated before the carriage.·Gears box shall be fixed reliably.·Measures to protect from wind,rainand moisture shall be taken.·Place it directly on the ground is notallowed3．PreservationWhen the driving device or the

driving device or reducer,otherwise,it might lead to human injuries or damage to the machine.2.FoundationThe reduction gearbox must be put on the foundation that has good rigidity,no vibration and is even.For example,the reducer can be put on the foundation frame that has a mechanically processed carrying plane,and the foundation frame should beconnected with concrete foundation.After alignment,the reducer box center should be positioned by the taper pin and then use the bolts to connect it with the foundation frame.3．Alignment1）Alignment of the motor and the reducer.The main shaft connects reduction gearbox and main motor must be in the same line with shaft of motor in the operation.In order to meet this need,axial horizon and vertical running must use special measuring device to measure.Specifically as shown below:Coupling type Radical running Axial running（R=200）Rigid coupling0.030.02Flexible coupling0.080.08If R>200mm，the axial running value can increase accordingly2）Installation and alignment of reducer box and grinding mill installation.·Before connecting to other machine please confirm the direction.Or the equipment will be damaged resulting from the wrong direction.·Never put too much impact pressure or too high loader because this will lead the damage to the bearing and rid of the lantern ring.·The installation of the reduction gearbox and the grinding mill must be right and careful.Disc and the thrust axis must be cleaned and not any stain should be left. The mouth size of the disc and the thrust axis unit’s connection must be measured and have detailed records.The connection between the disc and the thrust axis table bolts must be tightened.The thrust axis units connected to the disc cannot be deformed or distorted.The thrust axis station’s axial running tolerance cannot exceed0.13mm.3）Reducer installation and connection of the high and low pressure lubrication oil station:Reduction gearbox with high and low pressure lubrication oil station installation work must be properly detailed.Allocate pipe according to the scene.Low pressure oil outlet end of lubrication oil station and the inlet oil tube of the reduction gear box must be connected by steel pipe.All the16high oil pressure of the oil station outlet16tubes should be connected to the16high pressure sliding bearings of the reduction gear box.Please pay particular attention to:as there are4high pressure oil pump on the oil station,every high pressure pump leads4high pressure oil tubes, when connecting to gearbox,the four pumps’oil-out and gearbox’oil-inlet must be cross and linked uniformly.During the installation of the mill and gear box or in any other case,if the lubrication system does not work,never allow gearbox slowly rotate or jigger.Note that that the reducer box cannot reversion work.Ⅵ．Records of Field installation，Adjustment and Test Run1.Type of reduction gearbox2.Factory Number of reduction gearbox3.Specifications and models of grinding mills4.Specification,model,the power,speed,voltage,current of main drive motors5.Driving direction(From the main motor)6.Detailed record should be done in the process of alignment during installation,·Result record of alignment between reduction gearbox and the motor.·Result record of alignment between reduction gearbox and the grinding mill.7.Run-in testing recordStart work time：Year Month DayRun down time：Year Month DayGrinding mill load：Running time：No.Drivetimeyear-month-dayStopping timeyear-month-dayHostload（T）Motorstatorvoltage（V）Motorstatorstartingcurrent(A)Motorstatorworkingcurrent（A）Temp(。
