GENERAL INTRODUCTION ML20 vertical roller mill reducer transmit through the bevel gears combined with planet gears, a pair of bevel gears with a right angle transmission are connected with a set of planet transmission which

12、input shaft is perpendicularly upward through double-tooth coupling. The sun wheel is supported on the thrust disc by the spherical bearing, the axial support of the vertical mill is endured by the tilted thrust bearing with fan-shaped oil film, and this two freedom of motion make the inner ring and

13、 three planet wheels under the equal stress. Internal gear is rigidly fixed in the housing, the designed cylindrical housing provide the ideal support to the axial thrust bearing. In addition, cylindrical housing configure symmetrical ribs both at inside and outside, which let the house have strong

14、rigidity. The output shaft welded with the planet carrier, which make the configuration simple and reasonable.Bevel gears are Klingelnberg helix gears, and the sun gear and planet gears are involute spur gears. These gears all apply to the carburized carbon steel, gears feature high accuracy after c

15、arburizing and grinding.All the block bearings are the rolling bearings. Axial thrust bearings are the tilted thrust bearings composed of several fan-shaped bearing bushing, which can stand the axial force of the vertical mill. During operation, bearing bushing are directly submerged into the oil ta

16、nk and supplied fresh lubrication oil through the ring-type nozzles, to keep the tank always in a certain oil level, in such a manner, the mill can work for a period time when the lubrication system suddenly stop or other mechanical errors occur.Lubrication system is applied to separate oil pump sta

17、tion with pressure and self-protective system, which let the whole unit work safe and reliable.II. Characteristic parameter1. Operating environment Ambient temperature: -20C +40 C Ambient humidity: below 85%Environmental conditions: no corrosive gas, explosive gas or vapor. No dust and at better air

18、 exchange place.If have other special requirements besides the above ones, please contact us.If there are requirement for anti-explosion in open on the purchase order, our designers will consider it. It will be safe to install our products under our specification. The reducer should be installed at

19、this kind of place where it is convenient to carry out the inspection and maintenance work.The reducer should be installed on rigid support. 2.

Precautions Please confirm whether the packing is still in good condition before opening. Please take care when opens the packing.Check whether received

21、goods are coordinate with goods listed in the purchasing order. If improper products are used, it may cause injury or equipment broken.Do not remove the nameplate.2.Inspection requirementsThe following should be inspected when the driving device or gear reducer arrives. If there are some confusion o

22、r problems, please contact our sales department.(1) Whether items on the nameplate or things on the packing list are the same as them in the purchasing order.(2) Whether there are some damage caused by transportation.(3) Whether bolts or nuts are loose.Lifting, transportation & storage1. LiftingWhen

23、 lifting the reducer, its forbidden to stand below the reducer, as the dropt reducer may cause injury.Please note the lifting position shown in the drawing and lift the reducer with care.Please be careful when lifting the reducer since it may drop down or turn over. If there are lifting bolts or hol

24、es, one must use them when lifting. When lifting the whole set of reducer, one must use lifting holes in the lower housing, while it is forbidden to use them in the upper housing. However, after the reducer is installed to the equipment, do not use lifting bolts or holes to lift the equipment as it

25、may cause injury or machine broken.Please clarify the reducers weight before lifting from the nameplate, package, outline drawing or sample copy. If it exceeds the maximum lift capacity of the lifting device, please do not lift the reducer, as it may cause injury or machine broken.Note: It is forbid

26、den to lift the reducer with the output flange. 2. TransportationThe lubrication oil must be drained out before transportation.The reducer must be fastened tightly.Anti-wind, anti-rain and anti-moist protection must be adopted.It is forbidden to place the reducer directly on the ground.3. StorageIf

27、the driving device or reducer stops for a short period, it should be stored as follows:1) Proper place for storing The reducer should stay in a clean and dry place. Do not lay it out door or at this kind of place where may be humid, dusty and the temperature is changeful or contains corrosive gas. R

28、ust preventative oil must be painted to the input and output shafts.After dismantlement the lubrication oil pipes should be packed with vinyl resin to prevent foreign substances from getting inside.Anti-wind, anti-rain and anti-moist protection must be adopted. It is forbidden to place the reducer d

29、irectly on the ground.2) Storage periodThis period should not exceed the rust preventing period.If the storage period is longer than rust preventing period, the special anticorrosive specification is needed, please contact us.If this reducer is an exportation product, the anticorrosive specification

30、 for export products are needed, please contact us.Standard rust preventionOutside preventionThe reducer has been painted with rust preventative oil before delivery. The anti-rust status must be inspected in 6 months after delivery, and if it is necessary, it should be painted again.Inside rust prev

31、entionRust prevention period6 monthsStoring ConditionThere should be no humidity, no dust, less temperature change, no corrosive gas. Normally it should be lie in doors or in the storage area.3) Usage after storageBeing effected by temperature, ultraviolet radiation and other factors, seals are easi

32、ly aging and metamorphosing. Thus, the seals should be inspected before restart up the reducer after a long time storage, if the above mentioned happens, please replace them with new ones.When restarting up the reducer, please inspect whether there are abnormal noise, vibration or heating. If a brake is attached, please chec
