Description

SNAP RING GIVING CLAMPING LOAD OF AXIAL DIRECTION}

The present invention relates to a snap ring for applying a load in the axial direction, and more particularly, to form an elastic portion for applying an axial load to the snap ring to give an axial fastening load to prevent the shaft from shaking after the snap ring is assembled. It is about a snap ring.

Generally, a snap ring is a mechanical element that restricts the movement of an axis or boss, also called a retaining ring or retaining ring, and the snap ring is inserted into a groove formed on the outer periphery of the axis depending on where it is installed. It is also classified into a shaft snap ring and a hole snap ring inserted into a groove formed on the inner circumference of the hole.

In addition, the snap ring 10 is a ring-shaped ring to prevent the movement of the parts installed on the pin or shaft by inserting a groove in the hole or the hole in the shaft, such as transmission, agricultural machinery, construction equipment, ships, general industrial machinery, aircraft, Used for winches, pulleys, rotary wheels, roller bearings, vertical drive shafts and automotive parts.

On the other hand, the snap ring once installed in the shaft or hole can be removed through the snap ring pliers. That is, both ends of the snap ring are formed with a removal hole, so that an end of a snap ring plier is inserted into the removal hole, and when a force is applied to the snap ring pliers, the snap ring opens or contracts while being removed from the shaft or hole.

1 is a view showing a snap ring according to the prior art.

The snap ring 10 has a ring-shaped ring shape, and both ends of the snap ring 10 are formed with a predetermined gap. In addition, both ends can be seen that the removal hole 15 is formed so that the snap ring pliers are fitted to be fastened or dismantled. Snap ring 10 is free to move up and down relative to the gap because of the ring-shaped moss.

However, the existing snap ring 100 is formed to some extent with the member forming the shaft or hole when the rotating shaft penetrates the hole to support, causing vibration, vibration, and the like at the time of coupling. This vibration can act as an impact on a rotating member.

There is a problem of shortening the service life of the parts.

SUMMARY OF THE INVENTION An object of the present invention is to provide a snap ring in which a snap ring has an inclined portion capable of causing elasticity and the snap ring is assembled in a hole formed in an axis, a hub, or the like, and gives a fastening load in the axial direction to damp vibrations.

The present invention is provided in the snap ring is provided on the shaft or boss to limit the movement of the shaft or boss, the upper surface portion to be fitted into the groove formed in the shaft or boss, and connected to form an angle from the upper surface portion to the outside to be fastened in the axial direction Characterized in that it is formed of an inclined portion to give a load.

In addition, the inclined portion of the present invention is characterized in that the inclined protrusion portion shape at regular intervals.

According to the invention as described above, it is possible to apply a load in the axial direction at the time of fastening the snap ring between the shaft and the hole, and to prevent the shaking in the axial direction below any load region generated on the shaft.

In addition, the vibration in the axial direction can be prevented to prevent vibration and friction between the parts to increase the durability of the parts.

In addition, the snap ring can be manufactured in various shapes according to the required load, and produced at low cost, thereby supporting the axial fastening load.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

2 is a view showing a first embodiment of a snap ring according to the present invention, Figure 3 is a view showing a second embodiment of a snap ring according to the present invention. 4 is a view showing an application example of a snap ring according to the present invention.

Figure 2 is a snap ring with an inclined portion on the upper surface such that the snap ring can support an axial load. Snap ring 100 is inserted into the shaft or hole serves to limit the movement of the shaft or boss. A groove is installed at the outer circumference of the shaft, and the snap ring 100 is inserted into the groove to prevent the shaft from falling out of the hole when the shaft and the hole are connected. The inclined portion 120 is formed toward the outer circumference of the snap ring 100, and the inner circumference thereof is preferably formed of the flat portion 110 having a flat shape. At this time, since the flat part 110 and the inclined part 120 are connected to each other, the inclined part 120 is connected at a predetermined angle with the flat part 110 to impart an elastic force. Therefore, the snap ring 100 should be coupled to the groove 310 formed in the outer circumferential portion 350 of the shaft 300, so that the inner circumference has a planar shape so that the shaft is stably in the groove 310 of the shaft 300. It can support, the inclined portion 110 is to elastically support any member 340, it is possible to apply a fastening load in the axial direction. The snap ring 100 has a gap formed between both ends of the non-closed ring, and both ends of the snap ring 100 are provided with a stripping hole 150 into which a snap ring pliers (not shown) may be fitted. After the snap ring pliers are inserted into the stripping hole 150, the snap ring 100 can be opened to both sides so that the snap ring pliers can be inserted into or removed from the insertion groove of the groove or the hole formed in the outer circumference of the shaft, hub, and the like. Snap ring 100 may be coupled to the flat portion 110 and the inclined portion 120 by an adhesive, can be manufactured by pressing, etc., of course can be produced in various ways.

3 shows a second embodiment of a snap ring.

The snap ring 200 is formed of an inclined protrusion 220 connected outward from the upper surface portion 210 and the upper surface portion 210. As described above, the upper surface 210 has a shape similar to the existing snap ring, and the inclined protrusion 220 connected to the upper surface 210 is formed at regular intervals along the circumference of the upper surface 210. At this time, the inclined protrusion 220 is inclined downward by a predetermined angle to give a load, which is the same as the first embodiment described above. The material of the snap ring 200, the inclination angle of the inclined protrusion 220 and the flat part 210, the length of the inclined protrusion 220 and the number of protrusions may be determined according to the load generated on the shaft.

4 is a view showing an application example according to the snap ring of the present invention.

The shaft 300 is fastened to the through hole 340, and the snap rings 100 and 200 are coupled to the groove 310 formed at the outer circumference of one end of the shaft 300. In the snap rings 100 and 200, the upper surface portions 110 and 210 support the shaft above the shaft groove 310, and the inclination portion 120 or the inclination protrusion 220 is a member around the through hole 360. A load is applied to 340. The upper surface portions 110 and 210 of the snap rings 100 and 200 are applied to the shaft 300, and the inclined portion 110 or the inclined protrusion 220 is applied to the fastening member 340, respectively, to the shaft 300. It is possible to suppress axial shaking under any load that occurs.

In the above, the present invention has been described in detail by way of examples based on the embodiments of the present invention and the accompanying drawings. However, the scope of the present invention is not limited by the above embodiments and drawings, and the scope of the present invention will be limited only by the contents described in the claims below.
