Abstract
The utility model relates to a magnetic drain plug, including an oil plug containing an installing thread, characterized in that, permanent magnets are arranged on the upper and the middle of the oil plug body. The utility model has the advantages that, due to the permanent magnets enchase on the upper and the middle of the oil plug body, the free iron powder in the lubricating oil can be attacted at the lowest point of the gear case lubricating oil bath, which greatly avoids or reduces the free iron powder in the lubricating oil, also prevents the combining elements in the oil plug falling into the gear case to damage the gear caused by vibration.
Description
Technical field
The utility model relates to a kind of plug cock, the magnetic drain plug of especially a kind of energy anti-vibration.
Background technique
Plug cock generally places gear-box bottom lubricating oil bath minimum point, in the process of work, owing to often form the free iron powder after the pitch wheel wearing and tearing, and follow lubricating oil path to move at the Metal Contact face, quicken the wearing and tearing of Metal Contact face, and common plug cock is difficult to avoid or reduce free iron powder in the lubricant oil, during the rail traffic vehicles operation, gear-box can be subjected to continuous vibration, and to fall in the gear-box bad gear of card accidents caused because of vibration also to make in the plug cock composition element easily.
Summary of the invention
The purpose of this utility model is: can not avoid or reduce free iron powder in the lubricant oil at common plug cock, can not prevent in the vibration that composition element is fallen into bad gear of card in the gear-box in the plug cock, a kind of new magnetic drain plug is provided.
The purpose of this utility model is achieved in that a kind of magnetic drain plug, comprises containing the plug cock body that screw thread is installed, and it is characterized in that: be inlaid with permanent magnet on the plug cock body.
In the utility model: the permanent magnet post that is inlaid with concentric on the plug cock body.
Advantage of the present utility model is: owing to be inlaid with permanent magnet on the plug cock body, free iron powder in the lubricant oil will be pull-in on the minimum point in gear box lubricating oil pond, avoid or reduce the free iron powder of lubricant oil greatly, can prevent that also composition element is fallen into bad gear of card in the gear-box because of vibration in the plug cock.
Description of drawings
Fig. 1 is a kind of example structure schematic representation that the utility model relates to.
Among the figure: 1, plug cock body, 2, permanent magnet.
Embodiment
Accompanying drawing is nonrestrictive to disclose the structural representation of a kind of specific embodiment that the utility model relates to, and the utility model will be further described below in conjunction with accompanying drawing.
As seen from Figure 1, magnetic drain plug comprises and contains plug cock body 1 and the permanent magnet 2 that screw thread is installed.Permanent magnet 2 is embedded in the plug cock body 1 by interference fit.In the present embodiment, be inlaid with the permanent magnet post 2 of concentric on the plug cock body 1.
During concrete the use, magnetic drain plug is the same with common plug cock, before gear-box injects lubricant oil, earlier with the magnetic drain plug spinning on the fuel outlet bottom the gear-box; When oil change more, the fuel outlet from the gear-box bottom screws off magnetic drain plug earlier, bleeds off outmoded lubricant oil.
Claims (2)
1, a kind of magnetic drain plug comprises containing the plug cock body that screw thread is installed, and it is characterized in that: be inlaid with permanent magnet on the plug cock body.
2, magnetic drain plug according to claim 1 is characterized in that: the permanent magnet post that is inlaid with concentric on the plug cock body.
