Abstract

PURPOSE: A rubber band for preventing incoming soils and dusts into an excavator is provided to protect grease for preventing wear and to stably and efficiently prevent the infiltration of the soils and dusts. CONSTITUTION: In a rubber band molded by cubically combining a band and an O-ring, the rubber band for preventing soils and dusts of an excavator is composed of blades(4,6), a protruded part(5) and a recessed part formed in circumferential direction of an inner peripheral surface to keep elasticity at correspondent surfaces, and accordingly a bucket(a) and outer diameters(d,f) of an arm connecting part effectively contacted. In addition, the detachable rubber band includes a bolt(1), a T-shaped washer(2), and a T-shaped washer(3) having a nut.

Description

Dirt-Preventing Rubber Band For Excavators}

The present invention relates to a band used for an excavator bucket part (2 degrees, a) and an arm connection part (2 degrees, b), and more particularly, to a rubber band for preventing construction machinery excavator dirt, dust,

The construction machinery excavator has a body that can rotate 360 degrees and a boom, arm and bucket that move up and down around the connecting pin.

The grease (lubricant) is injected to each part that makes sliding contact with the connecting pins to prevent wear. However, when the excavation work, a large load makes sliding contact with soil and dust, so the wear rate is very high. (2 degrees, a) and the arm (2 degrees, b) connecting pins (2 degrees, c) is a lot of contact with soil and dust, so it is very important to block more effectively,

The bucket (2 degrees, a) and the arm (2 degrees, b) is connected to the wing (1 degree, 4. 6) and the inner circumferential center circumferential direction to block the inflow of dust in order to more effectively block the inflow of dust The acid (1 degree, 5) maintains elasticity with the corresponding surface (2 degrees, d. F) when the band is tightened, so that the grease (lubricant) can be maintained, and dirt and dust can be prevented more effectively.

It is conventionally used for the purpose of maintaining the "grease" (lubricant) injected into the connecting pin while contacting both sides with a simple circular rubber band shape, 0-ring (reference drawing). ,

The present invention is a rubber band formed by combining the present invention band and the conventional O-ring in order to effectively solve the above problems, while protecting the "grease (lubricant)" to prevent wear, rubber for preventing the inflow of dirt, dust more effectively Its purpose is to provide a band,

In order to achieve the above object, the present invention is formed with a blade (1 degree, 4. 6) and an acid (1 degree, 5) and a valley formed in the circumferential direction of the inner circumferential surface to block external soil and dust inflow. Insert the T-shaped washer (1 degree, 9) into the hole (1 degree, 8) at a right angle to the hole (1 degree, 8) at each position. Features of the present invention are detachable and attachable bands which are closely assembled around 1).

The present invention as described above is a wing (1 degree, 4. 6) to block the ingress of dust and dirt and the acid (1 degree, 5) formed in the center of the inner peripheral surface when the band is fastened to the corresponding surface (2 degrees, d.f. ) And keeps elasticity and protects "grease (lubricant)" more effectively blocking the ingress of dirt and dust

1 is a perspective view for explaining the assembly method and the inner peripheral surface of the rubber band,

2 degrees is a state coupled to the outer diameter of the contact portion of the bucket (2 degrees, a) and the arm (2 degrees, b) connection,

3 is a cross-sectional view of the present invention rubber band * Note: Cross section of conventional rubber O-ring

* Reference numerals and basic description *

1 degree: 1 (Assembly bolt) 2 (T-shaped washer) 3 (T-shaped washer and nut) 4. 6 (Band wing)

5 (mountain formed in the center of the inner surface of the band) 4, 6 (dirt, dust-proof wings)

2 degree: a (bucket part) b (arm part) c (bucket and arm part connecting pin) d (band outer diameter)

e (T-shaped washer (1 degree, 9) is inserted into the hole (1 degree, 8) 90 degrees)

The invention relates to a rubber band in which a band and an O-ring are three-dimensionally bonded and formed so that the wing (1 degree, 4.6) and the circumferential center of the inner circumferential surface (1 degree, 5) and the valleys are formed and formed, so that the bucket (2 degrees, a) and the arm connection (2 degrees, b) more closely adheres to the outer diameter (2 degrees, d, f), the lubricant "grease" is maintained, as well as the soil It effectively prevents the inflow of dust and prevents wear and removes and attaches the band. The assembly method uses the bolt (1 degree, 1), T-shaped washer (1 degree, 2) and T-shaped with nut (tab). There is a washer (1 degree, 3),

The T-shaped washers (1 degree, 2, 3) are for assembling and fitting the end faces (1 degree, 7) in a close and balanced manner with the relative cross-section. , 8) insert 90 ° right angle to the part, and then fix the band tightly around the bolt (1 degree, 1),

The present invention is an excavator soil, a band for preventing dust, three-dimensionally combined the advantages of the wing-shaped band for dust and the conventional "grease" O-ring, the elasticity on the surface (2 degrees, d. F) when tightening Keep it up. Since the wing (1 degree, 4. 6) and the mountain (1 degree, 5) and the valley are formed at the center of the inner circumferential surface in the circumferential direction, the bucket (2 degree, a) and the outer diameter of the arm connection (2 degree, d, f) maintains the "grease" more effectively because it maintains elasticity and closes more effectively, and also prevents abrasion caused by blocking dirt and dust from entering the outside,
