Abstract
Description
The present invention is an anti-loosening nut washer using an eccentric load.
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, the bolt is inserted into the structure member, and then a simple washer without a thread is inserted into the bolt and tightened in the order of tightening with a nut.
The present invention eliminates possible eye elements in order to solve the above-mentioned conventional problems,
The present invention is to provide an anti-loosening nut washer using an eccentric load for fastening the bolt and the nut and then fastening to the bolt after joining the structure to prevent the bolt and nut from loosening due to vibration and temperature difference.
The anti-loosening nut washer using the eccentric load of the present invention penetrates the inside of the
Also. The washer top end from the washer top end part 7 is structured in the form of an isometric ladder or ladder, with an inclination angle of 45 ° or less at 0.01 ° or more incline leading straight, so that the nut washer is fastened to the member and eccentric to the washer body when tightening. It is to provide excellent load preventing function by providing load.
The washer of the washer of the washer (1) makes an oblique angle from the end of the washer (8) to the washer (7) of the washer top surface of the nut body (1) and cuts at an angle of not less than 0.01 degrees and not more than 85 degrees but the thick of the nut body (1) It is made from the part and the incision line (6) is the loosening nut washer using the eccentric load, characterized by cutting the body to the size of less than one-third of the washer body (1)
In addition, the anti-loosening nut washer using the eccentric load of the present invention penetrates the inside of the groove (2) of the washer body (1) to form a gap between the thread (3) and the incision line (6) to smooth along the thread of the bolt The washer body 1 flows
The thread (3) of the anti-loosening nut washer using the eccentric load of the present invention is tightly wound and wound along the thread of the bolt, and is fastened to the one side of the nut to provide an excellent anti-loosening function.
In addition, the anti-loosening nut washer using the eccentric load of the present invention is to cut the cut line 6 of the washer body 1 to the size of less than one-third of the washer body (1) circumference to form a void by temperature When the washer body 1 shrinks and expands, the washer body 1 smoothly flows along the thread of the bolt, and the thread of the bolt and the
In addition, the outer circumferential surface of the washer body (1) of the anti-loosening nut washer using the eccentric load of the present invention is made of hexagonal, pentagonal, octagonal, square, circular and provides easy fastening using a tightening tool.
In addition, the assembly method for preventing the loosening of the anti-loosening nut washer using the inventor eccentric load is as follows.
First, insert the bolt into the structural member
Second, tighten the nut to the bolt inserted into the structural member.
Third, loosening prevention is performed in the order of tightening and fastening the anti-loosening nut washer using the eccentric load of the present invention on one side of the nut fastened to the bolt.
The present invention has the advantage of providing an anti-loosening nut washer using an eccentric load for fastening the bolt and the nut and then fastening to the bolt after the bolt and nut to join the structure to prevent the bolt and nut from loosening due to vibration and temperature difference. There is this
In addition, the outer circumferential surface of the washer body (1) of the anti-loosening nut washer using the eccentric load of the present invention is manufactured in a hexagonal, pentagonal, octagonal, square, circular, and has an advantage of providing easy fastening using a tightening tool.
In addition, there is an advantage to provide the following assembly method for preventing the loosening of the anti-loosening nut washer using the inventor eccentric load.
First, insert the bolt into the structural member
Second, tighten the nut to the bolt inserted into the structural member.
Third, loosening prevention is performed in the order of tightening and fastening the anti-loosening nut washer using the eccentric load of the present invention on one side of the nut fastened to the bolt.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
"Specifically look as follows" "Figure 1 is a perspective view showing an anti-loosening nut washer using an eccentric load, according to the present invention, the present invention bolts after fastening with a bolt and nut to join the structure To prevent the bolts and nuts from loosening due to vibration and temperature difference by close contact with the nut.
Bolts, nuts and washers are widely used to combine mechanical elements in machines and structures.
In particular, the coupling screw is designed by inserting a washer so that it does not loosen itself due to frictional force on the contact surface.However, when the vibration and shock are applied, the contact pressure decreases momentarily and almost no frictional force occurs. Since the screws of the structure and the device combined by the temperature deviation are loosened, a great problem occurs.
In order to solve this problem, the present invention provides an anti-loosening nut washer using an eccentric load.
The anti-loosening nut washer using the eccentric load of the present invention penetrates the inside of the
Also. The washer top end from the washer top end part 7 is constructed in the form of an isometric ladder or ladder with an inclination angle of more than 45 degrees at a degree of inclination of more than 0.01 degree which extends in a straight line. It is to provide excellent load preventing function by providing load.
Make a comb angle from the lower end of the washer of the washer body (1) to the upper end (7) of the washer of the nut body (1) and make an incline at an angle of more than 0.01 degrees to 85 degrees or less, but the incision line (6) is wide. Washer body (1) It is an anti-loosening nut washer using eccentric loads, characterized by cutting voids at a size less than one-third of the circumference.
In addition, the anti-loosening nut washer using the eccentric load of the present invention penetrates the inside of the groove (2) of the washer body (1) to form a gap between the screw thread (3) and the incision line (6) to smooth along the thread of the bolt The washer body 1 flows
The thread (3) of the anti-loosening nut washer using the eccentric load of the present invention is tightly wound and wound along the thread of the bolt, and is fastened to the one side of the nut to provide an excellent anti-loosening function.
In addition, the anti-loosening nut washer using the eccentric load of the present invention is to cut the cut line 6 of the washer body (1) to the size of less than one-third of the washer body (1) circumference to structure the void
When the washer body 1 shrinks and expands due to temperature, the washer body 1 smoothly flows along the thread of the bolt, and the thread of the bolt and the thread of the
When the washer body 1 contracts, it is widened, and when the washer body 1 is expanded, it is narrowed and flows. It is an anti-loosening nut washer using an eccentric load, characterized in that it closely adheres to one side of the nut and provides an excellent anti-loosening function.
In addition, the outer circumferential surface of the washer body (1) of the anti-loosening nut washer using the eccentric load of the present invention is made of hexagonal, pentagonal, octagonal, square, circular and provides easy fastening using a tightening tool.
In addition, the assembly method for preventing the loosening of the anti-loosening nut washer using the inventor eccentric load is as follows.
First, insert the bolt into the structural member
Second, tighten the nut to the bolt inserted into the structural member.
Third, loosening prevention is performed in the order of tightening and fastening the anti-loosening nut washer using the eccentric load of the present invention on one side of the nut fastened to the bolt.
