Abstract
The invention relates to a spindle bearing lubricating system for a wind driven generator. The spindle bearing lubricating system comprises a spindle bearing (1) and a bearing base (2) sleeved on the spindle bearing (1), wherein an oil inlet (21) and an oil return hole (22) are arranged on the bearing base (2); the oil inlet (21) is connected with an oil pump (4) through an oil transmission pipe (31); the oil pump (4) is connected with an oil tank (5) through an oil transmission pipe (32); the oil return hole (22) is connected with one end of an oil transmission pipe (33); and the other end of the oil transmission pipe (33) extends into the oil tank (5). With the adoption of the spindle bearing lubricating system for the wind driven generator, lubrication oil can be circularly used and flows back into the oil tank after a bearing is lubricated, so as to achieve sufficient lubrication and reduce pollution to an environment. A heater is arranged in the oil tank, so that when an environment temperature is lower, the heater heats the lubrication oil to ensure that the lubricating system normally operates; and when an oil level reaches an alarming value, the spindle bearing lubricating system can automatically alarm, so that the service life of the bearing is prolonged.
Description
[technical field]
The present invention relates to a kind of lubrication system, particularly a kind of mainshaft bearing of wind-driven generator lubrication system.
[background technique]
It is to adopt grease to lubricate mostly that wind driven generator principal shaft adopts the lubricious of independent axes bearing, and bearing itself is with closure not, and lubricating grease is not easy to preserve, and the blower fan main shaft low-speed heave-load is not easy to form oil film; Change relatively difficulty of oiling agent, bearing cleaning, the temperature change scope is little, the mobile non-constant of lubricating grease under the low-temperature condition; Below-5 ℃, lubricating grease can not flow, and the grease that from bearing roller, is extruded can not return participates in the raceway lubricating; Even the configuration automatic lubricator, when temperature below-5 ℃, the lubricating grease of squeezing into can only play lubrication near squeezing into a little; Lack the fat warning device and be difficult to realize, the lubricated waste discharge fat difficulty of grease, new lubricating grease promptly becomes degras through the running of six months; If can not be in time with its removing, remaining degras will produce initiate lubricating grease and pollute, and make initiate lubricating grease become degras very soon; The wearer of the on-stream generation of bearing can not in time be discharged, and remains in the lubricating function that wearer in the lubricating grease will reduce lubricating grease greatly, and life-span of bearing is produced greatly influence; The traditional bearing lubrication system adopts integrated bearing support, and it is big to take up space, and is inconvenient to operate.
[summary of the invention]
The technical problem that the present invention will solve is to provide a kind of mainshaft bearing of wind-driven generator lubrication system, and through this lubrication system, lubricant oil can recycle; After being lubricated bearing, lubricant oil flows back among the fuel tank, and fully lubricated, reduce pollution on the environment; Heater is set among the fuel tank; When ambient temperature was on the low side, heater heated lubricant oil, guaranteed that lubrication system runs well.
For realizing above-mentioned purpose, the present invention has adopted following technical proposal:
A kind of mainshaft bearing of wind-driven generator lubrication system; Comprise main shaft bearing, be nested with the bearing support on main shaft bearing; Bearing support is provided with oil inlet hole and spill port, and oil inlet hole is connected with oil pump through transport pipe, and oil pump is connected through transport pipe with fuel tank; Spill port is connected with transport pipe one end, and the transport pipe the other end extend in the fuel tank.
Be provided with filter between bearing support and the oil pump as stated.
Be provided with damper between bearing support and the oil pump as stated.
Be provided with the oil level oil temperature sensor as stated in the fuel tank.
Be provided with heater in the fuel tank as stated.
Oil level oil temperature sensor, heater and the controller and the alarm that are arranged at fuel tank top are connected as stated.
The invention has the beneficial effects as follows:
1, through this mainshaft bearing of wind-driven generator lubrication system, the lubricant oil in the fuel tank can recycle, and improves lubrication effect, reduces pollution on the environment;
2, this lubrication system has filter, can the lubricant oil that be input in the bearing be filtered, and improves lubricating quality;
3, this lubrication system has orifice valve, can increase the pressure of lubricant oil in the transport pipe, makes the conveying of lubricant oil steady;
4, this lubrication system has heater, and lubrication system is run well under the environment of weather cold, expands the scope that lubrication system conforms;
5, this lubrication system has alarm, and when the oil level of lubricant oil among the fuel tank was lower than warning value, system reported to the police automatically, reminds the timely make-up oil of staff, increases the service life.
[description of drawings]
