Abstract
The utility model discloses a novel end cover insulation structure for a wind driven generator. The novel end cover insulation structure comprises a bearing (7) and a bearing seat (2), wherein the bearing seat (2) is fixedly arranged on a motor end cover (1), the bearing seat (2) is provided with a cylindrical inner wall in contact with the outer wall of the bearing (7), the back end of the bearing (7) is provided with a bearing inner cover (8), the front end surface of the bearing inner cover (8) is in contact with an outer ring of the bearing (7), the front end of the bearing (7) is provided with an oil thrower (3), the oil thrower (3) is provided with a back end surface in contact with the outer ring of the bearing (7), and an insulating layer (6) is respectively arranged on the cylindrical inner wall of the bearing seat (2), the front end surface of the bearing inner cover (8) and the back end surface of the oil thrower (3) are respectively provided with an insulation layer (6). The novel end cover insulation structure has the beneficial effects that the effective insulation between a bearing body and the end cover is reached, the long-period insulation effect can be reached through the bearing insulation structure, in addition, the insulation mechanical performance of the bearing is reliable, and the effective protection effect on the metal surface is also realized.
Description
Technical field
The utility model relates to technical field of wind power generator, particularly a kind of novel wind generator end cap insulation system.
Background technology
Wind-driven generator running environment is abominable, very inconvenience of its lifting and replacing, and maintenance cost is extremely expensive, and therefore the reliability to wind-driven generator has very high requirement.
Wherein, the reliability of wind-driven generator middle (center) bearing part is particularly important.Require high accuracy, low vibration, low noise, dynamo bearing is in the state of continuous high speed work again, thereby the bearing arrangement designed rationality is most important.In order effectively to suppress the infringement of shaft voltage, when bearing arrangement designs, all need reasonably carry out the insulation processing of bearing to bearing.Bearing insulation structural design unreasonable not only directly influences useful life of bearing, also the integral bearing reliability of structure impacted, and finally because of bearing fault causes shutting down, produces maintenance work a series of complicacies, expensive then.
Insulated part has all adopted traditional laminated product in present stage numerous end cap insulation systems, the distortion of insulating material and make moist and cause failure of insulation and then cause bearing fault in long-term use.
The utility model content
The purpose of the utility model is to overcome the shortcoming of prior art, provides effective insulation can a kind ofly be provided, can reach the novel wind generator end cap insulation system that mechanical performance requires again.
The purpose of the utility model realizes through following technical scheme: a kind of novel wind generator end cap insulation system; It comprises bearing that is installed on the motor shaft and the bearing pedestal that is set in the bearing outside, and on electric motor end cap, bearing pedestal has a cylinder shape inner wall that contacts with bearing outer wall to bearing pedestal through bolt; The rear end of bearing is provided with internal bearing cover; Internal bearing cover is installed on the bearing pedestal, and the front end face of internal bearing cover contacts with bearing outer ring, and the front end that is positioned at bearing is provided with bearing end cover; Bearing end cover is installed on the bearing pedestal; And also be provided with oil scraper ring between bearing end cover and the bearing pedestal, oil scraper ring has one and the contacted rear end face of bearing outer ring, is provided with a layer insulating on the rear end face of the cylinder shape inner wall of bearing pedestal, the front end face of internal bearing cover and oil scraper ring.
Described insulating barrier is a teflon coatings.
The utlity model has following advantage: the utility model is provided with one deck teflon coatings insulating barrier contacting with bearing on part and the contact-making surface that bearing contacts; Thereby reached the effective insulation between bearing body and the end cap; And this teflon coatings insulating barrier has good moisture resistance, heat-resisting quantity, chemical resistance, high sheet resistance and extremely low coefficient of friction; Make this bearing insulation structure long-term insulation effect be guaranteed; Also improved the Mechanical Reliability of bearing insulation, also effective protective effect has been played in the metal surface.
