The daily movement of ball mill, those who cannot leave lube is lubricant, good lube conduces to the chance that reduces loss and unforeseen stoppage, can let an user be benefited fine is much. Brief introduction issues lube of gear mineral separation below. Gear oil of abbreviation of lube of gear mineral separation, it basically is used lubricant device of all sorts of mechanical gear mineral separation. Gear oil and internal-combustion engine lube are same, also by petrolatum model (or synthesis) base oil and corresponding additive are comprised. Gear oil can be divided for car gear oil and industrial gear oil two kinds big. The parts such as needle bearing of the gear change mechanism that car gear oil basically uses at machine of car, project, gear case that changes machine, around to drive axle, gimbal, on the part of gear mineral separation that still can be used at the corresponding bear such as vessel of tank, ship and working requirement. A formula that industrial gear oil basically uses at all sorts of bear conditions to fall, ajar type, close type and plant of mineral separation of worm wheel worm. The working requirement of gear oil reachs its action: The gear in orgnaizations of all sorts of mechanical mineral separation, what according to its axes mutual position affects is different, can divide for parallel axis mineral separation, intersect axial mineral separation and crisscross axis mineral separation. The appearance that gear and tine press in every kinds of mineral separation differs to have different mineral separation kind again, ; of gear of gear of cylinder of if the straight tine of parallel axis mineral separation is columnar gear, inclined tine, cylinder of person handwriting tine intersects of axial mineral separation have mineral separation of axis of crisscross of; of bevel gear of straight bevel gear, inclined tine, helix bevel gear have mineral separation of worm of hyperbola gear, worm wheel, helix. One.

Characteristic of gear mineral separation and 　 of requirement of gear oil work 1.

Efficiency of gear mineral separation is tall, efficiency of mineral separation of general and columnar gear can be amounted to 98% , compare with bearing photograph, the equivalent curve radius of gear is small, oily wedge condition is poor. 2.

Gear is line contact between mineral separation tine and tine, accordingly, osculatory area is small, unit contact pressure is high. Unit of average car gear contacts pressure to be able to amount to 2000-3000MPa, and hyperbola gear is higher, can amount to 3000 one 4000MPa. 3.

Gear mineral separation has line contact not only, still have sliding contact, especially hyperbola gear, its have taller opposite sliding velocity between teeth of a cogwheel, can amount to 8m/o left and right sides commonly. This falls in condition of high speed big negative charge, can make oily film attenuates local even burst, bring about attrition and wear away aggravate, cause even abrade and occlusive. 4.

The working temperature of gear oil is average relatively internal-combustion engine oil is low, change along with environmental temperature greatly and change, car gear oil is oily lukewarm general not prep above 100 degrees. Contemporary car uses hyperbola gear, because of its axes slants buy amount is larger, the opposite sliding velocity that can make when speed is high gear annulus face asks is very tall, make oily Wen Da goes to 160 degrees 180 degrees one. 2.

Gear oil is in the action 　 in gear mineral separation 1.

Reduce what gear reachs other motion part to wear away, prolong gear life. 2.

Reduce attrition, reduce power loss. 3.

Dispersive quantity of heat, have certain cooling effect. 4.

Prevent to corrode and rust. 5.

Reduce working noise, reduce the concussion effect between vibration and gear. 6.

Rinse contamination, develop the contamination between tooth flank especially, reduce wear away. CNC Milling CNC Machining
