Abstract
The utility model relates to a main gearbox for a middle-speed mill, which comprises an input spiral bevel gear shaft and a spiral bevel gear which is matched with the input spiral bevel gear shaft; the input spiral bevel gear shaft is connected with the spiral bevel gear, and connected with a planet wheel by a sun wheel; the planet wheel is connected with a planet frame by a planet shaft, and connected with a working machine by an output flange arranged on the planet frame and the planet shaft which are respectively provided with an oil tank. The utility model can be respectively provided with the oil tanks on the planet frame and the planet shaft; the oil tanks enable oil flow in the oil tanks to flow towards the sun wheel by inclined oil holes, and the sun wheel can get lubrication; the planet shaft is drilled with the oil tanks and the transverse flow oil holes flowing towards the planet wheel to enable the planet wheel and the bearing to get sufficient lubrication. The lubrication oil channel can avoid clogging, and the utility model has the advantages of good lubrication effect, small size, and reliable operation.
Description
The utility model relates to a kind of gearbox, particularly a kind of medium-speed pulverizer main-gear box.
In the prior art, the main transmission speed change that various vertical powder machineries adopt mostly is the input of vertical spin umbrella tooth greatly and is equipped with and gradually drives the gearbox that hardened face gear combines, its lubricated road is crisscross inside and outside casing, very numerous rope and complexity, stop up easily, another kind is that the main transmission gearbox is that spiral bevel gear is defeated, the vertical gearbox of planet output, lubricant passage way is also very numerous and diverse messy, stops up easily.
The purpose of this utility model be to provide a kind of simple in structure, volume is little, not susceptible to plugging a kind of medium-speed pulverizer main-gear box.
The utility model is such realization: a kind of medium-speed pulverizer main-gear box comprises that the associated spiral bevel gear of input spiral bevel gear axle is connected, be connected with planetary gear by sun gear, planetary gear is connected with planet carrier by planet axis, is respectively equipped with oil sump by linking to each other with working machine at output flange on the planet carrier on planet carrier, planet axis.
Compare with prior art, the utility model is to be provided with oil sump respectively on the planet carrier planet axis, oil sump makes the oil of oil sump flow to sun gear by inclined oil hole of air, sun gear is lubricated, being drilled with oil sump on planet axis makes planetary gear and bearing obtain sufficient lubrication with the cross-current oilhole that flows to planetary gear, this lubricant passage way can be avoided stopping up, and the high lubricating effect volume is little, and is reliable.
Be elaborated below in conjunction with the utility model.
Fig. 1 is a kind of medium-speed pulverizer main-gear box structural representation.
Fig. 2 is a kind of structural representation of lubricating oil bath parts of medium-speed pulverizer main-gear box.
As Fig. 1, shown in Figure 2, motor power (output) reaches spiral bevel gear 3 with its pairing by input spiral bevel gear axle 2, by sun gear 7 power is reached planetary gear 5 and tooth volume 6, by planetary gear power is passed to planet carrier 8, to pass to working machine by the output flange 9 that is connected on the planet carrier, bearing 4 is housed on the turning cylinder, upper-part is installed in the casing 1, the lubricating oil of grease pump is introduced into the top box of this gearbox, flow to the oil sump 10 on planet carrier top by the casing oilhole, make the oil of oil sump flow to sun gear by inclined oil hole of air, sun gear is lubricated, and another part is the cross-current oilhole that is drilled with oil sump on the planet axis 11 and flows to planetary gear, makes planetary gear 5 and bearing obtain sufficient lubrication, oilhole, oil sump all designs on parts, make inside and outside no special-purpose fuel tank of casing or oil sump, make product with compact structure, have enough lubricating oil in the oil sump all the time, can not produce because of oil-break makes bearing and gear gummed and cause damage parts, avoid obstruction simultaneously yet.
Claims (3)
1, a kind of medium-speed pulverizer main-gear box, comprise that the associated spiral bevel gear of input spiral bevel gear axle is connected, be connected with star-wheel by sun gear, planetary gear is connected with planet carrier by planet axis, link to each other with working machine by output flange on planet carrier, it is characterized in that on planet carrier, planet axis, being respectively equipped with oil sump.
