Description
Technical field
The utility model relates to a kind of special and supporting wind power speed-increasing device of wind-powered electricity generation unit, belong to the transmission of power speed change gear.
Background technique
At present, it is ripe that the technology of utilizing wind-force to generate electricity has been tending towards, as the wind-powered electricity generation unit of present 250KW, has blade to bear wind-force on this wind-powered electricity generation unit and rotating speed is passed to generator by the wind-force transmission shaft.Usually rotating speed is high more, and the generating efficiency of generator is just high more, and the wind-force rotating speed that blade is accepted is not high, and therefore, directly the wind-force rotating speed being reached generator, to carry out the effect of wind-power electricity generation not very good.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of wind-powered electricity generation connecting shaft speedup box that is connected between wind-force transmission shaft and the generator, it includes one by the input shaft of bearings in casing, be fixed with the planet carrier that has planetary gear train on the axle, be connected with sun gear with planetary gear train, be fixed with driving gear on this sun gear, and pay engagement through one-level fixed axis gear at least and link to each other with output shaft.
Described input shaft is supported on the casing by two selfaligning roller bearings, and its input end connects with fan blade by flange, and the other end has planet carrier with splined.
Described planet carrier links to each other with sun gear through planetary gear train, and the planet wheel shaft of planetary gear train supports the location by two selfaligning roller bearings, and the both sides of bearing respectively are provided with spacer ring, and sun gear connects with first order dead axle driving gear through a crowned spline.
Described dead axle driving gear is paid engagement by the secondary fixed axis gear and is linked to each other with the output shaft that is supported in the casing by two each selfaligning roller bearings.
The end cap separately of described output shaft and input shaft all adopts the gap to get rid of oil and packing combination seal, and the high-pressure oil pipe in the input shaft is a monolithic construction, and it is front loaded from input shaft, reaches output terminal always.
Casing described in the utility model is divided into four sections and vertical profile, and its preceding casing is the spheroidal graphite cast iron casing, and oil scale and fuel level sensor are housed on it, and is provided with three plane staircases, and preceding casing also is equipped with an air-strainer.
The brake joining plate that is 10 ° of installations with vertical line is housed on the described rear box, and purge cock is housed, magnetic plug screw, temperature transducer and ventilative cap.
The below of described rear box is provided with oil pump inlet port and flow-off, and connects with flange.
An oil distributor seat is equipped with at described casing top.
The utlity model has compactness rational in infrastructure, the speedup effect is obvious, and long service life is overhauled characteristics such as easy to maintenance, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a form structure schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model includes and is divided into four sections also casings 1 of vertical profile, so that install.Be supported with input shaft 3 with two selfaligning roller bearings 2 in the casing 1, this input shaft 3 connects with fan blade by flange, and it bears the weight and the end thrust of blade simultaneously, and transmits blade rotational speed.Input shaft 3 has planet carrier 4 through splined, and planetary gear train 5 is arranged on this planet carrier, and planet wheel shaft 6 wherein supports the location by two selfaligning roller bearings 7, and respectively there is a spacer ring on the both sides of bearing to make axially locating.Planetary gear train 5 is connected with sun gear 8, and this sun gear connects with first order dead axle driving gear 9 through a crowned spline, and pays 10 engagements through one-level fixed axis gear at least and link to each other with output shaft 11.The end cap of input shaft of the present utility model and output shaft all adopts the gap to get rid of oil and packing combination seal, and its good sealing effect and mounting or dismounting are convenient.The utility model has an integrated type high-pressure oil pipe 12, and front loaded from input shaft extends output terminal, in case high pressure oil leaks always.Shown in Figure 2, of the present utility model before casing be the spheroidal graphite cast iron casing, rational in infrastructure, intensity is reliable, and oil scale and fuel level sensor 13 are housed on it, and is provided with two platform staircases 14, so that climb during the maintenance gear case.On the preceding casing air-strainer 15 is housed also, but its not only oiling but also the cap usefulness of can doing to breathe freely.The utility model also is equipped with the brake joining plate that is 10 ° of installations with vertical line on rear box, and (not shown) such as purge cock, magnetic plug screw, temperature transducer, ventilative cap are housed, their mounting or dismounting are all very convenient, and the center hole of casing is worn, so that Bearing Installation.The utility model is owing to adopt pressure lubrication, and for guaranteeing the lubricated good of all gears and bearing, the special oil distributor seat 16 of adorning at the casing top bends thick steel pipe through one, branches to each little oil pipe and joint again, and each gear and bearing are fixed a point to lubricate.Oil pump inlet port and flow-off are positioned at rear box below (not shown), and connect with flange, and fuel sucking pipe is shortened, compact structure, and pressure loss is little.
