Abstract
The utility model relates to rolling bearings, in particular to a bearing for yawing in a wind-driven generator, which comprises an outer ring, an inner ring, a rolling part and a retainer. The outer ring is connected with the inner ring by steel balls, plugs are transversally arranged at connecting positions of the steel balls with the inner ring, the other ends of the plugs are fixed onto the inner wall of the inner ring, through holes are axially arranged on the plugs, pins are inserted into the through holes, oil nozzles are transversally disposed at connecting positions of at least one group of steel balls with the inner ring, and gear teeth are disposed on the outer ring. By means of adopting the structure, the integral bearing is compact in structure, convenient and speedy in installation and convenient in operation, and can realize excellent effect when used in a yawning structure of the generator.
Description
Technical field
The utility model relates to a kind of rolling bearing, particularly relates to the bearing that is used to go off course in a kind of wind-driven generator.
Background technique
In the wind-power electricity generation process, the wind wheel of wind power generating set should be in state down with the wind all the time.Promptly when wind direction changed, the wind wheel of wind power generating set also changed simultaneously.Therefore, generator set need be realized relatively rotating of cabin and pylon by the system that is made up of drive unit and driftage bearing, and the bearing enclose of driftage bearing is connected with pylon with the cabin of wind power generating set respectively.Make the wind wheel of generator set accurately to locate like this, be in state down with the wind all the time, make full use of wind energy and generate electricity.
Existing bearing is not very compact, and driftage bearing inconvenience is installed in wind-driven generator.The external treatment of some wind-power generating yaw bearing is not enough, not so durable in use.
Summary of the invention
The utility model technical issues that need to address provide a kind of easy to operate, and are simple in structure, compact, the wind-power generating yaw bearing of accurate positioning.
For solving the problems of the technologies described above, wind-power generating yaw bearing of the present utility model is made up of outer ring, inner ring, rolling element and retainer, the outer ring is connected with inner ring by steel ball, the joint of described steel ball and inner ring is horizontally arranged with obstruction, the other end that stops up is fixed on the inwall of inner ring, that stops up axially has a through hole, inserts pin in the through hole; The joint of at least one group of steel ball and inner ring is horizontally arranged with oil nozzle; The gear teeth are arranged on the outer ring.
After adopting such structure, the compact structure of whole bearing, it is convenient, easy to operate to install, and can play good effect in generator driftage structure.The pure zinc of thermal spraying on the bearing surface, and then coat epoxy resin paint.After these external treatment of process, bearing is just more durable in use.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the sectional view of the utility model wind-power generating yaw bearing.
Embodiment
Wind-power generating yaw device shown in Figure 1 is made up of outer ring, inner ring, rolling element and retainer, the outer ring is connected with inner ring by steel ball, the joint of described steel ball and inner ring 6 is horizontally arranged with stops up 8, the other end of obstruction 8 is fixed on the inwall of inner ring 6, stop up 8 axially have a through hole, insert pin 7 in the through hole, pin 7 mainly plays fixing effect.At least one group of steel ball 3 is horizontally arranged with oil nozzle 5 with the joint of inner ring 6, can add lubricant oil by 5 pairs of steel ball groups of oil nozzle, and the gear teeth 4 be arranged on the outer ring 1.Every group of steel ball 3 has two, becomes axial distribution, is communicated with between the two, can improve the shock resistance of bearing like this.Outer ring 1 is equipped with Stamping Steel Ribbon 2 with the joint of inner ring 6, mainly is to prevent that lubricant oil from leaking.Have bolt hole on the outer ring 1, convenient whole bearing fixing is on the pylon of wind-driven generator.
The pure zinc of thermal spraying on the bearing surface, and then coat epoxy resin paint, such processing can be so that whole bearing be more durable.
