Abstract
The utility model relates to a head oil tank for power-off protection of a bearing, which aims to solve the difficulty in power-off lubrication protection for an obliquely installed bearing. The oil tank is arranged at the top part of the bearing; an air filter is arranged at the top part of the oil tank to keep the interior air pressure and the external air pressure of the oil tank balanced; and a one-way valve is arranged between an oil outlet pipe and the oil tank. When the electricity is cut off suddenly or oil can not be supplied normally, the pressure in the bearing bush cavity is low due to the lack of oil, then the one-way valve is opened; and oil in the oil tank flows into the bearing bush cavity through the one-way valve and the oil outlet pipe under the action of gravity, thereby achieving the lubrication protection function. The utility model has the characteristics of simple structure, obvious effect, convenient installation and the like, and is suitable for the power-off protection of inclined bearings.
Description
Technical field
The utility model relates to a kind of bearing fuel tank, especially a kind of bearing power-off protection top petrol tank.
Background technique
Use in the bearing power-off protection apparatus at common electric machine, roughly have three kinds: 1. oil ring protection; 2. disc protection; 3. top petrol tank protection.
But with in the bearing, because motor tilts to install, the also corresponding inclination of bearing is so the protection of common oil ring is inadvisable in inclination motor; because disc device space is bigger, the oil level of certain altitude will be arranged simultaneously again, but bearing tilts to install; oil level is too high, and so leakage of oil easily is also inadvisable.Top petrol tank is installed in from the height of motor 5～10m aerial, and trouble is installed.For the inclination motor bearing, common several protections have been unsuitable for providing power-off protection for it.
Summary of the invention
The purpose of this utility model is the problem at the bearing outage lubrication protection difficulty of tilt installing, and designs a kind of simple in structure, bearing power-off protection top petrol tank that effect is remarkable, easy for installation.The technical solution of the utility model is so to realize:
A kind of bearing power-off protection top petrol tank; comprise fuel tank (2); be located at oil level device (3), oil inlet pipe (1), oil outlet tube (7) on the fuel tank; described fuel tank (2) is located at the top of bearing; oil inlet pipe (1) is located at a side of fuel tank (2); fuel tank (2) opposite side below is provided with oil outlet tube (7), the top is provided with return tube (5), and the top of fuel tank (2) is provided with an air filter (4), is provided with one-way valve (6) between oil outlet tube (7) and the fuel tank (2).
The utility model is at the problem of the bearing outage lubrication protection difficulty that tilts to install; fuel tank (2) is located at the top of bearing; the top is provided with air filter (4) and keeps fuel tank (2) inside and outside air pressure balance; be provided with one-way valve (6) between oil outlet tube (7) and the fuel tank (2); when sudden power or can not normal fuel injection the time; the bearing shell oil pocket is inner because oil starvation reduces pressure; this moment open check valve (6); oil in the fuel tank (2) plays the lubrication protection effect flowing in the bearing bush chamber by one-way valve (6) and oil outlet tube (7) under the effect of gravity.The utlity model has simple in structure, effect is remarkable, characteristics such as easy for installation.Be applicable to inclination bearing power-off protection.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: with reference to the accompanying drawings; a kind of bearing power-off protection top petrol tank; comprise fuel tank (2); be located at oil level device (3), oil inlet pipe (1), oil outlet tube (7) on the fuel tank; described fuel tank (2) is located at the top of bearing, and oil inlet pipe (1) is located at a side of fuel tank (2), and fuel tank (2) opposite side below is provided with oil outlet tube (7), the top is provided with return tube (5); the top of fuel tank (2) is provided with an air filter (4), is provided with one-way valve (6) between oil outlet tube (7) and the fuel tank (2).
Under the motor normal working, the Lubricating-oil Station normal fuel injection is given bearing, make the inner oil pocket of bearing shell be full of oil, pressure oil is supplied with all the time, makes the inner and extraneous pressure difference that forms of bearing shell, make the mobile trend of oily oriented top petrol tank (2) of bearing inside, because the bearing bush internal pressure is greater than fuel tank (2) internal pressure, one-way valve (6) is in normally off, and the oil that flows to by oil inlet pipe (1) in the fuel tank (2) goes out not go, fuel tank (2) beginning oil storage is full of the oil back and overflows from return tube (5).When Lubricating-oil Station breaks down or sudden power; in the time of can not normal fuel injection; the bearing shell oil pocket is inner because oil starvation reduces pressure; when oil pocket pressure is brought down below top petrol tank (2) pressure; one-way valve (6) is opened; oil in the fuel tank (2) flows in the bearing bush chamber by one-way valve (6) and oil outlet tube (7) under the effect of gravity, plays the lubrication protection effect.
Claims (1)
1. bearing power-off protection top petrol tank; comprise fuel tank (2); be located at oil level device (3), oil inlet pipe (1), oil outlet tube (7) on the fuel tank; it is characterized in that fuel tank (2) is located at the top of bearing; oil inlet pipe (1) is located at a side of fuel tank (2); fuel tank (2) opposite side below is provided with oil outlet tube (7), the top is provided with return tube (5), and the top of fuel tank (2) is provided with an air filter (4), is provided with one-way valve (6) between oil outlet tube (7) and the fuel tank (2).
