Description
Technical Field
The utility model relates to a wind-powered electricity generation trade technical field specifically relates to an independent low viscosity main shaft lubricating oil filters, cooling device.
Background
The main shaft is one of the core components of the entire wind power plant. The connecting piece of the engine room and the wind wheel is also an important component for connecting the speed-up gearbox.
The lubrication of the main shaft at present mainly relies on grease lubrication and there is no cooling system. The discharged grease is cleaned and scrapped by an oil receiving disc. The normal working temperature of the main shaft is 30-40 ℃, and the grease is sticky at the temperature. Grease with large pressure on the front bearing seat and the rear bearing seat cannot completely and fully enter a fit clearance in real time to form a good oil film for lubrication. The roller, the main shaft and the front and rear bearing seats are hard extruded when part of the fans work in the state for a long time. Finally, the service lives of the main shaft of the wind power generation equipment, the double-row roller bearing, the front bearing seat and the rear bearing seat are shortened, and the maintenance cost is high. This patent application is made in view of this.
Disclosure of Invention
Low viscosity main shaft lubricating oil filter cooling device, its design aim at solve above-mentioned prior art problem and make lubricating oil through using low viscosity lubricating oil, enter into each fit clearance in real time fully and form the lubricating oil film to improve the live time of lubricating oil, reduce extravagantly, and played good lubrication and cooling effect.
In order to achieve the design purpose, the low-viscosity spindle lubricating oil filtering and cooling device mainly comprises a front bearing seat, a rear bearing seat, a sealing cover, a hydraulic filtering station and a flow divider; wherein,
the main shaft is connected with the front bearing seat and the rear bearing seat, and the sealing covers are arranged on the front bearing seat and the rear bearing seat;
the hydraulic filtering station is respectively connected with an oil collecting position of the sealing cover and an oil inlet of the flow divider;
the flow divider is used for respectively injecting the filtered lubricating oil back to the front bearing seat and the rear bearing seat through the oil pipe.
Above basic design utilizes the sealed cowling recess to accomplish the collection to leaking lubricating oil, filters through hydraulic pressure filtering station, and the cooperation ambient temperature cools off lubricating oil to can improve lubricating oil life.
The improved structure is based on the sealing and isolating dustproof structure of the sealing cover and the bearing seat, a labyrinth type sealing ring can be arranged between the sealing cover and the bearing seat, and the sealing ring is fixed on the main shaft and rotates together with the main shaft;
a fit clearance is formed between the sealing cover and the sealing ring; the inner wall of the sealing cover is provided with a hairbrush.
The improved optimized measure is that the front bearing seat and the rear bearing seat are provided with temperature sensors which monitor the temperature of the main shaft part in real time.
In summary, the lubricating oil filtering and cooling device for the spindle has the advantages that the sealing position of the spindle adopts labyrinth sealing, and the sealing covers are arranged on the front bearing seat and the rear bearing seat to fully isolate the oil leakage position from the external environment. The lubricating oil that flows out is collected the bottom recess department of cover by sealed cowling drainage plate. Then enters a hydraulic filtering device through an oil suction pipe, is filtered and finally is shunted to each oil filling port by a shunt. The device realizes the filtration of low-viscosity lubricating oil and utilizes the external environment to carry out natural cooling. Good lubricating and cooling effects on the main shaft, the front bearing seat and the rear bearing seat. Impurities in the fit clearance are removed in time, and pollution of external sand blown by wind and dust to the lubricating oil is isolated through labyrinth sealing.
Drawings
FIG. 1 is a schematic diagram of the structure and operation of a low viscosity spindle lubricating oil filtering and cooling device;
FIG. 2 is a schematic view of a seal arrangement of the seal housing and bearing housing;
as shown in fig. 1 and 2, the upper sealing cover 1, the sealing ring 2, the fitting gap 3, the first brush mounting portion 4, and the second brush mounting portion 5 are provided.
Detailed Description
The invention is further illustrated by the following figures and examples.
Embodiment 1, as shown in fig. 1, a low viscosity spindle lubricating oil filtering and cooling device includes front and rear bearing blocks, a sealing cap, a hydraulic filtering station and a flow divider; wherein,
the main shaft is connected with the front bearing seat and the rear bearing seat, and the sealing covers are arranged on the front bearing seat and the rear bearing seat;
the hydraulic filtering station is respectively connected with an oil collecting position of the sealing cover and an oil inlet of the flow divider;
the flow divider is used for respectively injecting the filtered lubricating oil back into the front bearing seat and the rear bearing seat through oil pipes;
the front bearing seat and the rear bearing seat are provided with temperature sensors, the temperature sensors monitor the temperature of the front bearing seat and the temperature of the rear bearing seat in real time, and when the working temperature is exceeded, the temperature is fed back to the master control system for alarming.
After the low-viscosity lubricating oil flows out through the fit clearance, the lubricating oil is concentrated to the groove collecting position through the drainage plate of the sealing cover;
guiding the flowing lubricating oil into a hydraulic filtering device through an oil suction pipe to filter impurities finely;
and the filtered lubricating oil flows out of each oil injection pipe through the shunt and is re-injected into the front bearing seat and the rear bearing seat through environmental cooling.
The temperature sensor monitors the temperature of the bottom of the bearing seat in real time and feeds the temperature back to the master control system, and when the temperature exceeds the normal working temperature, an alarm signal is sent out to stop the machine for maintenance.
As shown in fig. 2, a labyrinth seal ring 2 is arranged between an upper seal cover 1 and a bearing seat, and the seal ring 2 is fixed on a main shaft and rotates together with the main shaft;
a fit gap 3 is formed between the upper seal cover 1 and the seal ring 2 to prevent friction between the upper seal cover 1 and the seal ring 2.
The inner wall of the upper sealing cover 1 is provided with a first hairbrush mounting part 4 and a second hairbrush mounting part 5, and the dust and the leaked lubricating oil are fully separated by the hairbrush. Even the round angle that fine hair, sand and dust dropped the hang plate appears also can collect fine hair, sand and dust and can not drop inside the sealed cowling.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are considered to be within the scope of the invention as defined by the following claims.
