Abstract
The present invention is an eccentric washer that is fastened between the bolt and the nut for joining the structure but close to the nut to prevent the bolt and nut from loosening due to vibration and temperature difference.
Bolts, nuts and washers are widely used to combine mechanical elements in machines and structures.
Especially, the coupling screw is designed by inserting the washer so that the friction is not released by the contact surface. However, when the vibration and shock are applied, the contact pressure decreases momentarily and the friction force is almost disappeared. In order to solve this problem, the present invention provides an eccentric washer for releasing anti-wedge action.
Eccentric washer to prevent wedge action of the inventor
While the groove 2 is perforated in the center of the washer body 1, the wedge action starts at one side of the lower part of the washer 8 and extends to one side of the end of the lower side of the washer 8 at an angle of less than 45 degrees at an angle of 45 degrees or less. At an oblique angle
In addition, while the groove 2 is perforated in the center of the washer body 1, the wedge starts at one side of the upper washer 7 and extends to one end of the opposite washer upper 7 at an angle of 45 degrees or less at an angle of not less than 0.001 degrees. It is an eccentric washer with an anti-wedge action that is formed by giving an eccentric ladder or ladder shape to form an oblique angle that acts.
In addition, the inventors of the present invention, the eccentric washer to prevent the wedge acts according to the shape or structure of the washer body (1), flat washer, spring washer, dish washer, gluing washer. Tongue washer, lock washer, square washer, band washer, Manufactured with insulated washers, turtle washers, and nut washers, the eccentrics in the form of isometric ladders or ladders are also included in the scope of the claims as they give a wedge angle for wedge action to washers used for washers.
Eccentric washer to prevent wedge action, washer body (1), washer lower part (8), washer tilted part to one end of the lower part (8) (7) The inclination to the side of one end of the tip, which is wedged at an angle of more than 0.001 degrees to less than 45 degrees, eccentric in the form of an isometric ladder or ladder,
Description
The present invention is an eccentric washer with an anti-wedge action.
Bolts, nuts and washers are widely used to combine mechanical elements in machinery and structures. The main role of washers is to keep the bolts and nuts unstable.
In general, bolts, nuts and washers used as a means for conventional coupling are designed to prevent self-release due to frictional force generated at the mating contact surface, but when the vibration and shock are applied, the contact pressure decreases instantaneously and the frictional force almost disappears. If this phenomenon is repeated, the screws are loosened and the combined structures and devices are dismantled, which causes a great problem.
In addition, conventionally, after inserting the bolt into the structure member, a simple washer that is not provided with eccentricity is inserted and tightened by tightening with a nut, so that the nut is easily loosened due to vibration or temperature change.
The present invention eliminates possible eye elements in order to solve the above-mentioned conventional problems,
The present invention is to provide an eccentric washer to prevent wedge action by forming an eccentric in the form of an isometric ladder or ladder by giving a wedge angle to the washer to prevent the bolt and nut from being loosened by vibration and temperature difference. to be
The present invention is an eccentric washer to prevent wedge action
While the
In addition, while the
The present invention has the advantage of providing an eccentric washer to prevent loosening by forming an eccentric in the form of an isometric ladder or a ladder to prevent the bolt and nut from being loosened by vibration and temperature difference.
In addition, there is an advantage of maintaining the stability of the structure by providing an eccentric washer to prevent the release wedge action of the present invention
In addition, there is an advantage that the construction cost is greatly reduced by cope with the eccentric washer that has the low cost cost because of the simple structure and easy to manufacture the anti-loosening nut with high price cost.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
"In detail, it looks like this"

In addition, the screw of the structure and the device coupled by the temperature deviation is loosened, so a great problem occurs
In order to solve this problem, the present invention provides an eccentric washer to prevent wedge action.
Eccentric washer to prevent wedge action of the inventor
While the
In addition, while the
The inclined angle of the wedge action starting from one side of the washer
The inclined angle of wedge action starting from one side of the washer
It is mainly provided as being divided into larger and smaller angles than the helical angle of the thread of the bolt nut, which is set with the eccentric washer acting as the anti-loosening wedge, and larger than the pore angle following the thread of the bolt nut.
In addition, the nut is configured to set the eccentric washer to prevent the loosening wedge action in the washer
It is in close contact with one side and tilted so that the thread inside the nut is strongly in close contact with the thread of the bolt in the form of a wedge so that the void is reduced, and the friction surface is more, which corresponds to the expansion and contraction force of vibration or temperature change.
In addition, the eccentric washer that acts as an anti-wedge acts to change the direction of movement of the vibrating vibration to the direction of the comb angle given to the anti-ease eccentric washer.
It is characterized by providing the anti-loosening function by lifting the one side of the nut assembled in close contact with the washer by the wedge action of the screw thread inside the nut.
In addition, the inventors of the present invention, the eccentric washer to prevent the wedge acts according to the shape or structure of the washer body (1), flat washer, spring washer, dish washer, gluing washer. Tongue washer, lock washer, square washer, band washer, Manufactured with insulating washers, turtle washers, and nut washers
In addition, the eccentricity in the form of an isometric ladder or a ladder is given to the washer acting as a wedge to the washer used for the washer, which is included in the claims.
In addition, the inventors of the present invention is an eccentric washer to prevent wedge action is made of metal, non-ferrous metal, plastics, synthetic resins
