Abstract
The utility model discloses a planetary gear bearing positioning structure of a wind power gear box. One end of a planet shaft (3) is fixed on the side wall of a planet carrier (1); the diameter of the other end of the planet shaft (3) is slightly large, a stepped surface is formed at the end, and the stepped surface and the side wall of the planet carrier (1) position two bearings (4) axially; and the planet shaft (3) has a hollow structure, a bolt (2) is arranged in the planet shaft (3), penetrates the planet shaft (3), is connected with the side wall of the planet carrier (1), and pre-tightens the two bearings (4) axially. The bearing can be positioned axially by only controlling the dimensional tolerance of width of distance rings without requirement on tolerance of axial dimension between two side arms of the planet carrier, thus enabling processing to be simpler; and the planetary bearings are pre-tightened axially by the bolt, thus reducing adjusting pads used in the existing planetary bearing positioning structure, and enabling the operation to be more convenient.
Description
Technical field
The utility model relates to a kind of wind-powered electricity generation gear-box planet wheel bearing support device, relates in particular to the wind-powered electricity generation gear-box planet wheel bearing position structure that adopts the bolt axial pretightening.
Background technique
The present planetary bearing taper roller bearing supporting way that adopt more, be not easy to control in Bearing Installation process middle (center) bearing orientation type, should be by the spacerband width tolerance of size between two pairing bearings be controlled, again the axial dimension tolerance between the planet carrier two side arms is strict with, processing is caused difficulty.In addition, bearing pre-tightened is by adjusting operation inconvenience to the spacer between bearing and the planet carrier.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of axially locating easy, the easy-operating wind-powered electricity generation gear-box of pretension planet wheel bearing position structure.
The technical solution of the utility model is as follows: a kind of wind-powered electricity generation gear-box planet wheel bearing position structure, be fixed with planet axis on the planet carrier, be with planetary pinion on this planet axis, described planetary pinion is bearing on the planet axis through two bearings, separate by distance ring between described two bearings, its key is: described planet axis one end is fixed on the planet carrier sidewall, the bigger formation step surface of planet axis the other end end diameter, and this step surface and planet carrier sidewall are to two bearing axially locating; Described planet axis is a hollow structure, is provided with bolt in this planet axis, and this bolt passes planet axis and is connected with the planet carrier sidewall, and two bearings are carried out axial pretightening.Utilize the pretension of bolt to adjust distance between planet carrier sidewall and the planet axis the other end end step surface, come two bearings and distance ring axially locating.Do not need complicated strict tolerance to calculate in the process component process.
Have oilhole on the planet axis sidewall of above-mentioned hollow, this oilhole communicates with oil inlet hole on the distance ring.Communicate planetary bearing is carried out splash lubrication.
Above-mentioned bearing is a tapered roller bearing.
Beneficial effect: the utility model is owing to only need can finish axially locating to bearing by the width dimensions tolerance of control distance ring, and the axial dimension zero allowance requirement between the planet carrier two side arms makes processing simpler; And by bolt planetary bearing is carried out axial pretightening, reduced the spacer part in the present planetary bearing position structure, more convenient operation.
