Problems solved by technology

[0004] The transmission chain form of the above-mentioned high-speed generator sets is heavy due to the insufficient integration of the transmission chain; the semi-direct drive generator set has the risk of oil leakage from the gearbox due to the integration of the gearbox, and the shaft current of the generator causes electric corrosion of the gearbox bearing and generator electric shock. The magnetic force acts on the bearing of the gearbox, leading to the disadvantages of premature failure of the bearing life

Embodiment 1

[0030] like figure 1 , figure 2 In the embodiment shown, a high-speed wind turbine with high integration is characterized in that, the high-speed wind turbine with high integration comprises: a main shaft 1, one end of the main shaft is fixedly connected with the impeller; a gear transmission assembly, the The gear transmission assembly includes an input end and an output end 14, the input end of the gear transmission assembly is fixedly connected with the other end of the main shaft; a generator 16, the input shaft of the generator is fixedly connected with the output end of the gear transmission assembly .

[0031] The gear transmission assembly includes a first-stage planetary gear 8, a first-stage sun gear 11 and a first-stage planetary carrier 7, the first-stage planetary carrier is the input end of the gear transmission assembly, and the first-stage planetary carrier is connected to the main shaft. Fixed connection.

[0032] The first-stage planet carrier is fixedly ...

Embodiment 2

[0046] The difference from the first embodiment is that a shock absorber bracket 28 is fixed on the outer side of the gear box, the inner side of the shock absorber bracket fits the outer contour of the gear box, and the outer contour of the shock absorber bracket is circular, so the outer contour of the shock absorber bracket is circular. The plurality of shock absorbers are evenly spaced on the outer edge of the shock absorber bracket, and the shock absorber bracket is provided with a plurality of hollow areas.

[0047] The circular shock absorber bracket can better transmit the force, so that the sudden vibration is evenly transmitted to each shock absorber, and the hollow area set on the shock absorber bracket can provide deformation space to prevent the reduction box body when the vibration is too large. cause damage and deformation.

[0048] Therefore, the present invention has the following beneficial effects: (1) Compared with the prior art, the transmission chain of t...

Abstract

The invention discloses a high-integration-level high-speed wind generating set, which is characterized in that the high-integration-level high-speed wind generating set comprises a main shaft, an impeller, a wind generating set, a wind generating set and a wind generating set, the gear transmission assembly comprises an input end and an output end, and the input end of the gear transmission assembly is fixedly connected with the other end of the main shaft; and an input shaft of the generator is fixedly connected with the output end of the gear transmission assembly. Compared with the prior art, the transmission chain is higher in integration level, a primary planet carrier main bearing is omitted, the main shaft is directly and fixedly connected with the primary planet carrier, torque transmission stability is improved, meanwhile, the gear transmission assembly is fixedly connected with the main shaft, the gear box is fixedly connected with the bearing seat, a gear box elastic support and a torque arm are omitted, cost is lower, the weight is lighter, and economical efficiency is higher.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a high-integration high-speed wind power generating set. Background technique [0002] In a wind turbine, the main drive chain is the core component of the wind turbine, and its performance directly affects the cost of the entire wind turbine, the reliability of the unit's operation, and its market competitiveness. At present, the main layout forms of the main transmission chain with gearbox for large wind turbines are divided into the following categories: the first category is that the gearbox is separated from the main bearing seat, and the gearbox can be either a high-speed gearbox or a medium-speed gearbox (half-speed gearbox). Direct drive type), the gearbox can be separated from the generator or integrated into one; the second type is the integration of the gearbox and the main bearing, the gearbox box and the main bearing seat are rigidly connected, because the size o...
