Abstract

The invention relates to a wind power generation main bearing which belongs to the aerogenerator field, the wind power generation main bearing is characterized by comprising a main bearing upper limb, a main bearing lower limb, an anti-thrust cylindrical roller and a holder; the inner sides of the main bearing inner limb and the main bearing lower limb are provided with two rows of anti-thrust cylindrical rollers; the outer side of the main bearing inner limb is provided with a single row of centripetal cylindrical rollers and the cylindrical rollers are placed on the holder. The bearing of the invention saves a main shaft so that the impact of an original stiff shaft on a gear box and a generator can be reduced greatly and the service life of the gear box and the generator can be prolonged; the transmission of power can be realized well and the main bearing of the invention is easy to be repaired and detached. The main bearing can stand axial force with big load and big radial load, which can be well suitable for the working condition of aerogenerators with no main shaft, thus meeting the stress requirements of the aerogenerator.

Description

1. Technical field [0001] The invention relates to a main bearing for wind power generation, which belongs to the field of wind power generators. 2. Background technology [0002] At present, the structure of the known wind power generator with gearbox is that the main bearing is placed in the main bearing seat, the main bearing seat is fixedly connected with the nacelle floor, one end of the main shaft is connected with the wheel hub, and the other end is connected with the gearbox through the main bearing seat, and the gearbox Connected to generator. This structure is rigidly connected, and the main shaft has a great impact on the gearbox and generator, which may easily cause premature damage to the gearbox, and it is extremely inconvenient to repair and disassemble. 3. Contents of the invention [0003] The purpose of the present invention is to provide a main bearing for wind power generation that can reduce the impact on the gearbox and the generator, prevent the gea...
