Description
Technical field
The utility model is a kind of Oscillating Tooth Gear Reducer speedup box, particularly a kind of Oscillating Tooth Gear Reducer speedup box that is used for wind-driven generator.
Background technique
The gear speedup case of wind-driven generator of the prior art is the vitals of wind power plant, at present based on the multi-stage planetary gear transmission, particularly high-power gear speedup case more than hundreds of kilowatts, its complex structure, bulky, deal is heavy, the manufacturing process complexity, need high-precision big apparatus processing, so cost an arm and a leg.
Chinese patent CN200975458, a kind of coaxial dicyclo oscillating tooth planetary transmission is disclosed, the type of belt drive of this speed changer adopts axle two ring gear with small teeth difference transmissions, and the characteristics of Oscillating Tooth Gear Reducer have been absorbed and a kind of novel oscillating tooth speed changer that designs, this transmission ratio scope is big, bearing capacity is big, for Oscillating Tooth Gear Reducer increases newtype.The described gearbox of this model utility adopts planetary transmission, drive mechanism complexity, very flexible.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provides that a kind of bearing capacity is strong, friction factor is little, volume is little, in light weight, the Oscillating Tooth Gear Reducer speedup box that is used for wind-driven generator of low cost of manufacture.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of Oscillating Tooth Gear Reducer speedup box that is used for wind-driven generator, comprise movable teeth rack, shock wave device, oscillating tooth, eccentric bushing and output shaft, the teeth groove of described movable teeth rack is embedded with oscillating tooth, the two sides of oscillating tooth is complementary with shock wave device with rotating mechanism and contacts, be provided with eccentric bushing in the shock wave device, be socketed with output shaft in the eccentric bushing;
Described rotating mechanism comprises the cycloid ring gear, and the two sides of oscillating tooth is complementary with shock wave device with the cycloid ring gear and contacts, and oscillating tooth rotates with the track of cycloid ring gear;
Perhaps rotating mechanism comprises the pin tooth, and the pin gear cover is connected to pin gear sleeve, and the pin tooth is evenly distributed in the pin wheel housing, and oscillating tooth is complementary with shock wave device with pin gear sleeve and contacts.
Cycloid ring gear inward flange described here has the profile of tooth exterior feature, and the profile of tooth exterior feature is a hypocycloid, and the profile of tooth exterior feature is contacted to be oscillating tooth, and oscillating tooth is contained in the movable teeth rack, and the another side of oscillating tooth contacts with shock wave device, and shock wave device is enclosed within outside the eccentric bushing, assembling output shaft in the eccentric bushing.When movable teeth rack rotated its drive oscillating tooth by external force together, oscillating tooth made shock wave rotate again, and the eccentric bushing and the output shaft that are contained in the shock wave device are also followed rotation together.The number of teeth of oscillating tooth and hypocycloid gear ring be to differ from one or two, output shaft rotates with the velocity ratio speedup of setting.Cycloid ring gear, movable teeth rack, shock wave device, oscillating tooth, eccentric bushing and output shaft have been formed the speed increasing mechanism of pure rolling, and cycloid ring gear and oscillating tooth are realized multiple tooth engagement.Make the speedup box bearing capacity strong, the output torque is big, and noise is low: because the Oscillating Tooth Gear Reducer velocity ratio is big, so volume is less, weight is lighter, the planet step-up gear ratio with same gear ratios has only its 1/2nd.The cycloid ring gear also can replace with pin wheel housing, is provided with pin gear sleeve in pin wheel housing uniformly, is provided with the pin tooth in the pin gear sleeve, and the mode of motion is identical with the cycloid ring gear.
As preferably, the flank profil in the described cycloid ring gear is a hypocycloid, or hyperbola.Profile of tooth is wide to be the rolling that hypocycloidal shape will help oscillating tooth, and hypocycloid can provide favourable track for the rolling of oscillating tooth.
As preferably, described oscillating tooth is a roller, or a kind of in the roller, needle roller, steel ball.
As preferably, the oscillating tooth number in the described movable teeth rack in the teeth groove and the difference of the flank profil number in the cycloid ring gear and the pin number of teeth in the pin wheel housing are 1 or 2.According to the size of Oscillating Tooth Gear Reducer speedup box velocity ratio, change oscillating tooth number gets final product with the ratio of the wide number of profile of tooth.
Therefore, the utility model provides a kind of Oscillating Tooth Gear Reducer speedup box that is used for wind-driven generator, and multiple tooth engagement, bearing capacity is strong, transmission efficiency is high, noise is low, compact structure, volume are little, in light weight, manufacturing process is simple, need not high-precision large equipment, cost is low.Little, in light weight owing to volume simultaneously, the corresponding also reduced size of wind driven generator yaw mechanism that brings, weight reduction is for gross investment has brought certain economic benefits and social benefit.
