Abstract

PURPOSE: A bolt-nut coupling method using a beveled washer is provided to prevent the loosening of bolt-nut coupling and maintain the stability of a structure. CONSTITUTION: A bolt-nut coupling method is as follows. A washer(2) is fitted to a bolt shaft(9) of a bolt and located on one side of a bolt head. A member(3) and a beveled washer(4) are fitted to the bolt shaft so that the beveled washer is located on one side of the member. A nut(5) is tightened along bolt threads(1) of the bolt shaft. The washer and the beveled washer are tightly fastened with the member interposed. The nut is tightened to press the beveled gear against one side of the nut and apply an eccentric load to the nut.

Description

Fastening method for bolt nut loosening using comb angle washer {omitted}

The present invention is a bolt nut loosening fastening method using a comb washer Bolts, nuts and washers are widely used to combine mechanical elements in the machine and the structure, the main role of the washer is to keep the bolts and nuts not to loosen

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.

The present invention eliminates possible eye elements in order to solve the above-mentioned conventional problems,

The present invention is to provide a bolt nut loosening fastening method using a comb angle washer to prevent the bolt and nut from loosening due to vibration in order to combine the structure that is not loosened by vibration.

In the present invention to prevent loosening coupling method using a comb washer

The washer used in the bolt nut loosening fastening method using the bevel angle washer of the present invention is to function as a washer, including the original spring, plate-shaped disc spring, disc ring type, gluing type, the upper and lower ends of the washer 45 degrees or less at an angle of more than 0.01 degrees Isometric trapezoidal or trapezoidal made of oblique angle washer (4) is provided to be easily fastened using a tightening tool

The bolt nut loosening fastening method using the comb washer of the present invention has the advantage of preventing the bolt and nut from loosening by vibration by combining the structure and maintaining the stability of the structure

In addition, bolt nut loosening fastening method using a comb washer is easy to assemble and dismantle, the manufacturing cost of the comb washer (4) is small, there is an advantage of providing a low cost of assembling the structure for the loosening prevention structure.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

"In detail, it looks like this"

1 is a plan view showing a bolt nut loosening fastening method using a comb angle washer according to the present invention,

Insert the washer (2) from the bolt shaft (9) of the bolt to position on one side of the bolt head, and then insert the member (3) from the bolt shaft (9) and then insert the comb washer (4) from the bolt shaft (9) Positioning the member 3 on one side;

After the step by tightening the nut (5) along the bolt screw thread (1) from the bolt shaft (9) with the washer (2), the comb washer (4) in close contact assembling

Unfastening bolt nut using a comb washer, characterized in that the step of tightening the nut 5 was pushed strongly on one side of the nut (5) by acting an eccentric load on the nut (5). Prevent fastening method

The bolt nut loosening fastening method using the present comb washer made of an equilateral trapezoid or trapezoid which forms a comb angle of more than 45 degrees at an oblique angle of more than 0.01 degrees, and a comb washer made of a plateless spring, a plate-shaped disc spring, and a disc ring type ( 4) Provides bolt nut loosening fastening method using comb washer with excellent loosening function by providing elasticity and great tension.

In addition, the washer used in the bolt nut loosening fastening method using the bevel angle washer of the present invention is to function as a washer, including the original spring, plate-shaped disc spring, disc ring type, gluing type washer upper and lower ends at an angle of more than 45 degrees 0.01 degrees Isometric trapezoids or trapezoids made of oblique angles in Fig. 2 are made of comb washer 4 and are provided to be easily fastened using a tightening tool.

In addition, when the vibration of the assembled structure is applied to the fastened nut (5), the vibration is transmitted to the beveled portion of the isometric trapezoidal comb washer (4) which forms an oblique angle of 45 degrees or less at an angle of more than 0.01 degrees to give an impact By changing the direction of the vibration energy transmitted by the comb washer (4) forming an oblique angle around the bolt shaft (9)

The screw and bolt thread (1) formed on the inner side of the nut (7) are staggered as if they are lifted with a lever, and the wedge action is tightened more powerfully, resulting in an excellent loosening prevention function.
