Description
Technical field
The utility model relates to the gear-box that a kind of cement industry vertical roller grinder is used, belong to gear drive.
Background technique
Along with global energy day is becoming tight, more and more higher to the requirement of the protection of environment simultaneously, consume rich and influential family's cement industry as global energy, rise more and more higher to the requirement of energy-saving and emission-reduction.Vertical roller grinder is little with its floor space, less investment, energy-saving effect is obvious, utilization rate of raw materials is high and gradually by universally acknowledged, obtained the approval in the world, thereby becomes the standard configuration on the cement production line.
At present, vertical roller grinder mainly contains two kinds of forms with the structure of speed reducer: a kind of is that the one-level spiral bevel gear adds the one-level Gear Planet Transmission; Second kind is that the one-level spiral bevel gear adds the two-stage parallel axis transmission; For first kind of form, because the velocity ratio of speed reducer is bigger, the velocity ratio of the two poles of the earth transmission is all bigger, and simultaneously, the scale of cement line is also increasing now, requires the transmitted power of speed reducer also increasing, makes the spiral bevel gear specification very big.Domestic present situation is that the large-scale spiral umbrella gear can't be processed at all at present, relies on import fully, has increased cost of production and manufacture cycle greatly.Simultaneously, because the speed ratio of planetary stage is also bigger, the diameter of sun gear is too small, can not well guarantee the working life of gear-box.To second kind of form, because the speed ratio of roller mill speed reducer is bigger, maintainability is required to make that than higher the gear-box volume of this form is very big, be unfavorable for processing and cost control, cause sizable wasting of resources simultaneously; Simultaneously, because the volume of this gear-box is too huge, make the operation of gear-box very unreliable, this form is superseded substantially now.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of cost that can effectively lower system is provided, and significantly reduces the manufacture cycle of gear-box, reduces the vertical roller grinder gear-box of maintenance the risk and cost.
The purpose of this utility model is finished by following technical solution, it is mainly by casing, the transmission of first order spiral bevel gear, the second level driving of parallel axes, the transmission of third level planetary pinion is formed, described input shaft is placed in the casing by bearing, and its inner is fixed with bevel pinion, and is engaged with a bevel gear wheel and constitutes the transmission of first order spiral bevel gear by this bevel pinion; With the coaxial parallel stage small gear that is fixed with of described bevel gear wheel, this small gear and gearwheel engagement also constitute the second level driving of parallel axes; With the coaxial sun gear that is fixed with of described gearwheel, this sun gear has planet wheel by gear engagement, and planet wheel links to each other with a planet carrier by stationary axle, and planet carrier is connected with and can drives the output flange that the vertical roller grinder upper millstone rotates.
Crowned teeth cover in the middle of being provided with one between described gearwheel and the sun gear, gearwheel end axle join by crowned teeth with sun gear end axle and are connected together mutually with the crowned teeth cover.
The utility model adopts three grades of transmissions, can reduce the bevel gear of gear-box greatly, and it is homemade that bevel gear is realized fully, saves foreign exchange; Simultaneously, low price, the cycle is fast, and is guaranteed, can reduce the later maintenance expense and the risk of gear-box greatly.Simultaneously,, make the structure of gear-box little, in light weight, can reduce the cost of whole gear-box, save investment, reduce the operation cost of system owing to be three grades of transmissions.
