Description
(1) technical field
The present invention relates to wind power technology, is exactly a kind of vertical pivot wind power generation gear case specifically.
(2) background technique
Gear-box in the wind power generating set is an important mechanical part, and its main function is that the transmission of power that wind wheel is produced under the wind-force effect is given generator and made it obtain corresponding rotating speeds.Usually the rotating speed of wind wheel is very low, does not far reach the desired rotating speed of generator for electricity generation, must be used for by the speedup of gear-box gear pair realizing, so also gear-box is referred to as speedup box.According to the general arrangement requirement of unit, will be integrated with gear-box with the transmission shaft (being commonly called as macro-axis) that the wind wheel wheel hub directly links to each other sometimes, also have macro-axis and gear-box are arranged respectively, the structure of utilizing tensioner covering device or shaft coupling to connect therebetween.In order to increase the stopping power of unit, usually input end or the output terminal at gear-box is provided with braking device, cooperates blade tip braking (fixed slurry is apart from wind wheel) or become slurry jointly the unit transmission system to be carried out Associated brake apart from braking device.Because unit is installed in places, air port such as high mountain, wilderness, seabeach, island, be subjected to the wind-force effect of irregular break-in varying duty and the impact of strong gusts of wind, stand the influence of the scorching summer and freezing winter and the extreme temperature difference throughout the year, physical environment of living in is in addition had inconvenient traffic, gear-box is installed in the small space of cat head, in case break down, repair very difficulty, so to its reliability with all proposed the requirement more much higher working life than common mechanical.For example, under conventional state, the mechanical property, also should have characteristic such as cold-check resistance under the low-temperature condition to the requirement of construction material; The gear-box smooth working be should guarantee, vibration and impact prevented; Guarantee sufficient lubricating condition, or the like.To the huge area of summer in the winter temperature difference, dispose suitable heating and cooling device.Also the monitory point to be set, remote control is carried out in running and lubricating status.Multi-form wind power generating set has different requirement, and the setting type of gear-box and structure are also therefore and different.The most common in wind-powered electricity generation circle horizontal axis wind-driven generator group with fixing parallel-axes gears transmission and planetary pinion transmission.As previously mentioned, wind-power electricity generation is subjected to the influence of natural condition, the appearance of some special meteorological conditions, all may cause the wind-powered electricity generation unit to break down, and narrow and small cabin can not be as have firm support basis ground, the power coupling of whole drive unit and the factor of torsional vibration are always embodied a concentrated reflection of on certain weak link, and a large amount of facts have proved, this link usually is the gear-box in the unit.Therefore, strengthen research, pay attention to its work of carrying out maintaining is seemed particularly important gear-box.Present widely used wind power generation gear case, installation form are horizontal axis, 3～4 grades of transmissions, and the transmission chain length mostly is external introduction, does not have independent intellectual property right, and the accuracy of manufacturing of gear is required high (more than 5 grades).Material and heat treatment etc. require also very high, but still are difficult to solve this ubiquitous difficult problem of broken teeth.
(3) summary of the invention
The object of the present invention is to provide a kind of transmission efficiency height, vertical pivot wind power generation gear case that volume is little.
The object of the present invention is achieved like this: it is made up of casing and one-level speed increasing mechanism, and casing connects the one-level speed increasing mechanism.
The present invention also has following technical characteristics:
(1) described casing comprises upper casing, lower housing, support, internal gear and lower velocity shaft, and lower velocity shaft connects upper casing, and upper casing connects lower housing and internal gear, and lower housing connects support.
(2) described one-level speed increasing mechanism comprises flexible supporting device, lower support dish, excentric sleeve, back shaft, upper support dish, first planetary pinion, eccentric crankshaft, second planetary pinion and high speed shaft, flexible supporting device connects the lower support dish, the lower support dish connects back shaft, high speed shaft and eccentric crankshaft respectively, eccentric crankshaft connects upper support dish, lower support dish, first planetary pinion and second planetary pinion respectively, back shaft connects the upper support dish, and high speed shaft connects coupling and excentric sleeve respectively.
Main feature of the present invention is: the vertical pivot structure, the one-level transmission, multiple tooth engagement, because mounting structure changes the overall height dimension that makes a whole set of wind generating unit and reduces about 60% (about 80 meters of existing level axle wind power generation gear case device pylon height, about 35 meters of vertical pivot wind power generation gear case device pylon height), and cancelled driftage, change slurry two cover transmission devices, greatly reduce the manufacture, installation, maintenance cost.Be the transmission of one-level transmission speedup, Transmitted chains is short, and transmission efficiency is up to about 95%.Axial dimension is short simultaneously, is that existing level axle wind power generation gear case can't be realized.Vertical pivot wind power generation gear case of the present invention is multiple tooth engagement simultaneously, and bearing capacity is big, and pure rolling, transmission accuracy height greatly reduce the hidden danger that exists of broken teeth phenomenon.Engagement one-level speedup transmission in adopting, and internal gear made the part of casing, compare with existing level axle wind power generation gear case drive technology, its volume under the prerequisite that realizes identical function, weight reduces about 30%.
