Abstract
Disclosed is a lubricating arrangement for planetary gear, which is a lubricating arrangement and specifically relates to a lubricating arrangement for the planetary gear of yaw or pitch gearbox used for wind generators. The lubricating arrangement for planetary gear comprises a planet carrier, a planetary gear, a needle bearing and a planetary shaft, wherein the both ends of the planet shaft are fixed on the two side boards of the planetary carrier, the planetary gear is mounted on the planet shaft through the needle bearing, and oil orifices for lubricating the needle bearing are arranged on the planetary shaft or planetary gear. Oil orifices for lubricating the needle bearing arranged on the planetary gear are so designed that at least one oil orifice is started from the tooth root of the planetary gear and ended at the needle bearing. And, the oil orifices for lubricating the needle bearing arranged on the planetary shaft are so designed that an axial oil orifice is arranged on the planetary shaft and at least one oil orifice laterally introduced into the oil orifice of the needle bearing. The objective of the utility model is to provide a novel lubricating arrangement to solve the practical lubrication problem of needle bearing on the planetary gear of yaw or pitch gearbox used for wind generators.
Description
Technical field
The utility model relates to a kind of lubricating fitting, especially a kind of technical field that is used for the planet wheel lubricating fitting of wind-driven generator driftage or variable propeller gearbox.
Background technique
Driftage is one of vitals of wind-driven generator with variable propeller gearbox.Its effect is the angle that is used for regulating engine rooms of wind power generators or blade, makes it adapt to the variation of wind direction or wind-force.Because operating mode is more abominable, inconvenient maintenance adds that installing space is narrow and small, and driftage all has strict requirement with variable propeller gearbox to reliability, weight, boundary dimension.Reduce the radial dimension of gear-box when increasing bearing capacity, the needle bearing that bearing capacity is strong, installing space is little is often adopted in the supporting of planet wheel.Because driftage is all adopted flooding system lubrication with each planetary stage gear of variable propeller gearbox and bearing, but the needle bearing radial dimension is little, axial length is big, is installed in the space of relatively sealing, is difficult to obtain lubricated fully.
Summary of the invention
The purpose of this utility model is: the practical problem at the lubricated difficulty of needle bearing in existing wind driven generator yaw and the variable propeller gearbox provides a kind of new lubricating fitting.
The purpose of this utility model is achieved in that a kind of lubricating fitting of planet wheel, comprise planet carrier, planet wheel, needle bearing, planet axis, the two ends of planet axis are fixed on the planet carrier biside plate, planet wheel is installed on the planet axis by needle bearing, and planet wheel or planet axis are provided with the oilhole that needle bearing is lubricated.
The oilhole that needle bearing is lubricated that is provided with on the planet wheel is: at least one arises from the oilhole that the planet wheel tooth root terminates in needle bearing.
The oilhole that needle bearing is lubricated that is provided with on the planet axis is: planet axis is provided with an axial oilhole, and at least one is imported the oilhole of needle bearing by axial oilhole.
The utility model adopts technique scheme, compared with prior art has following advantage:
The utility model is provided with single-row on planet wheel or the multiple row radial direction oil hole, and oilhole is communicated with the tooth root and the endoporus of planet wheel.An axial oilhole is set on planet axis, and the single-row or multiple row radial direction oil hole vertical with axial oilhole, axially oilhole is positioned at the center of planet axis and runs through the two ends of planet axis, and radial direction oil hole is vertical with axial oilhole, connection shaft to oilhole and with the cylindrical of planet axis.Lubricating structure is simple, and oilhole is processed than being easier to, and can realize that continuous and reliable is lubricated to needle bearing.
