Abstract
The utility model provides a fillings-removing screw bolt. The inner part of a magnetism nonconducting and stainless screw bolt is provided with a high magnetic Nd-Fe-B alloy, and the top part of the screw bolt forms a concave circular table shape. The high magnetic Nd-Fe-B alloy can be made into a cylinder or other blocks, and a conducting magnetic circular iron block is placed on the high magnetic Nd-Fe-B alloy. The utility model adopts an Nd-Fe-B permanent magnet with the highest magnetic performance at present to use as a magnetic material which is used for removing iron filings of the inner part of a motorcycle engine. The material has the advantages of good magnetic performance and low cost. Although the curie temperature of the magnetic material is about from 310 DEG to 410 DEG, the internal temperature of the engine can not reach the temperature even when the engine runs at a high speed. Tested by practice, the demagnetizing quantity of the utility model is small.
Description
Technical field:
The utility model relates to a kind of bolt, the especially a kind of Fillings-removing screw bolt that can remove each parts phase iron filings that mutual friction produces of motor internal cause.
Background technique:
The former waste lubricating oil bolt of putting in motorcycle engine bottom, the outlet of waste oil during only as oil change more, and do not play the purposes that motor is had other.Because the running of motor exists friction and the generation iron filings between each parts, not only the infringement to each parts of engine interior strengthens, and causes the life-span of each parts to reduce, but also reduces the safe-use period of lubricant oil.Up to the present, also not having a kind of is to be directly installed on motor to remove the device of iron filings and sell on market or use.
Summary of the invention:
The purpose of this utility model provides a kind of bolt that can remove the engine interior iron filings continuously, and it is simple in structure, and is easy to use, the efficient height.
Technical solution adopted in the utility model is: high magnetic Nd-Fe-B permanent magnet is housed in the non-magnetic stainless steel bolt, and the top of bolt is recessed frustoconic shape.High magnetic neodymium iron boron can be made cylindrical body or other bulk.Be placed with a magnetic conduction round iron piece on the high magnetic neodymium iron boron.
The utility model adopts the highest Nd-Fe-B permanent magnet of present magnetic property as the magnetic material of removing the inner iron filings of motorcycle engine.This magnetism of material can be good, and the charge is small.Though the Curie temperature of this magnetic material is about 310～410 ℃, even at the motor that runs up, its inside temperature does not reach this temperature far away yet.Through actual tests, its demagnetization amount also is very little.
The utility model is simple in structure, cost is low, and is easy to use, replaces former motorcycle engine bottom with it and puts the waste lubricating oil bolt, the iron filings that inner each the parts running of motorcycle engine can be produced are removed incessantly, simultaneously the lubricant oil of motor are purified.Promptly prolong the safe handling time of lubricant oil, also increase the life-span of each parts of engine interior.Between running-in period, use this bolt at new car, it is more smooth suitable that inner each the parts break-in of motorcycle engine is got, and it is more identical that cylinder and piston break-in are got, and improved the overall performance of motor.
Description of drawings:
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model plan view.
Embodiment:
The utility model is made up of the iron nahlock 3 of non-magnetic stainless steel bolt 1, strong magnetic neodymium iron boron 2, magnetic conduction.The high magnetic neodymium iron boron cylindrical body 2 of 8.0 * 10.0 millimeters of φ is housed in 8.1 * 12.0 millimeters of the hole φ of stainless steel bolt 1, and high magnetic neodymium iron boron can be cylindrical body, square cylinder or other bulk, loads onto the iron block 3 of φ 8.1 * 2.0 then.Recessed 1.5 millimeters of the finished product top that assembles is recessed frustoconic shape.This model utility is replaced former the putting after the waste lubricating oil bolt in motorcycle engine bottom, and motor is because the iron filings that running produces will be inhaled the recessed round platform place at this bolt firmly.Because the strong magnetic action that neodymium iron boron produces, even the lubricant oil of Liu Donging rapidly also is difficult to iron filings that hold are taken away, when oil change more, the iron filings of inhaling on the bolt top can be wiped, continue use then.
