Description
Technical field
This utility model relates to a kind of lubricant passage way, a kind of to the lubricant passage way of ring gear engaging piece in planet circular system.
Background technology
Wind-power electricity generation is generated compared with the lubricant passage way electricity of ring gear engaging piece in planet circular system with traditional firepower, there is the free of contamination advantage of generating, compared with hydroelectric generation, there is capital construction low cost, floor space little, the convenient advantage of maintaining, the most large-scale water-power plant, storage reservoir is also easy to cause downstream certain potential safety hazard.Gear-box is the critical component of wind-driven generator, and in wind-driven generator, gear-box the most all uses multistage planet train.Although gear-box is improved by someone, casing carried out the classification of necessity, preferably resolve dismounting difficulty, it is to avoid replacing assembly, decrease maintenance cost.In planet circular system, the load born due to planetary gear and gear ring in gear-box is the biggest, sufficiently lubrication is must assure that during work, lubricating system currently for meshing face of inner gear ring typically uses splash system lubrication, we have found that, when the liquid level of lubricating oil is too low, the lubricant housings that frequently can lead to ring gear cannot obtain lubricating oil, for this, people are set to point to the jet of ring gear on casing, although this mode can ensure that also can obtain lubrication in the case of lubricating oil liquid level is relatively low, but there is injection dead angle, can not effectively ensure that lubricating oil covers whole lubrication face.The most preferably solve the lubrication of ring gear, become the technical problem that this area is paid close attention to.
Utility model content
The purpose of this utility model is: cannot lubricate the gear ring field of conjugate action liquid level is low when for traditional splash lubrication mode, and the jet being set to point to ring gear on casing but exists the series of problems such as injection dead angle, it is provided that a kind of.
The purpose of this utility model is achieved in that a kind of to the lubricant passage way of ring gear engaging piece in planet circular system, including the forced feed lubrication oil duct in casing, it is characterized in that: planet carrier and casing intersection are provided with the ring shaped oil passage of closing, ring shaped oil passage is linked up with the forced feed lubrication oil duct in casing, being provided with fuel injection passage and oil transportation channel in planet carrier, fuel injection passage is linked up with ring shaped oil passage by oil transportation channel；Described fuel injection passage is parallel with meshing face of inner gear ring, at least provided with a jet pointing to ring gear on fuel injection passage.
In this utility model: described ring shaped oil passage is made up of casing, planet carrier and sealing ring, sealing ring is positioned at casing and the joint portion of planet carrier relative motion, the entrance of oil transportation channel is located on the ring shaped oil passage wall of planet carrier side, and the oil-out of forced feed lubrication oil duct is located on the ring shaped oil passage wall of case-side.
In this utility model: be provided with the jet of three equally distributed sensing ring gears on fuel injection passage, jet is furnished with Radix Rumicis shower nozzle.
The utility model has the advantage of: owing to planet carrier and casing intersection are provided with the ring shaped oil passage of closing, the lubricating oil of the forced feed lubrication oil duct in casing can be induced one the oil transportation channel in planet carrier by ring shaped oil passage, owing to the fuel injection passage in planet carrier is parallel with meshing face of inner gear ring, at least provided with a jet pointing to ring gear on fuel injection passage, especially three jets are uniformly distributed, jet is furnished with Radix Rumicis shower nozzle, and the whole work surface of ring gear can be made all to obtain lubricating oil.
