Description
본 고안은 부시에 관한 것으로써 보다 상세하게는 부시의 내측에 마찰계수를 현저히 감소하기 위한 볼베어링이 설치되어 부품의 마모에 의한 파손을 방지하며 오랫동안 사용할 수 있도록 한 회전력을 감소 시키는 볼이 설치된 부시에 관한 것이다.The present invention relates to a bush, and more particularly, a ball bearing is installed inside the bush to significantly reduce the coefficient of friction, thereby preventing damage caused by abrasion of parts and reducing the rotational force for a long time. It is about.
일반적으로 부시란 회전체인 축과 고정체인 하우징 또는 축과 베어링 사이에 설치되어 축으로부터 여타 하우징 및 베어링의 마모와 파손을 방지하는 것으로 재질은 비교적 값이싼 황동이나 청동으로 만들어 사용된다.In general, the bush is installed between the shaft and the housing of the rotating body or between the shaft and the bearing to prevent wear and breakage of the other housing and the bearing from the shaft. The material is made of brass or bronze which is relatively inexpensive.
이는 회전체인 축과의 마찰로 인하여 상기 축과 접하는 부분의 마모 및 파손에 따른 수리 및 교환시 용이하도록 하기 위해서 이다.This is to facilitate the repair and replacement due to the wear and damage of the part in contact with the shaft due to the friction with the shaft of the rotating body.
즉 첨부도면 도1에 도시된 바와같이 축(200)과 베어링(300) 사이에 설치되며 단일의 재질로 이루어진 부시(100)는 베어링(300)의 내경과 부시(100)의 외경은 억지끼워맞춤으로 삽입 설치되고, 부시(100)의 내경과 축(200)과는 헐거움끼워맞춤으로 설치된다.That is, as shown in Figure 1 attached between the shaft 200 and the bearing 300, the bush 100 is made of a single material is the inner diameter of the bearing 300 and the outer diameter of the bush 100 is fitted fit It is inserted and installed, the inner diameter of the bush 100 and the shaft 200 is installed in a loose fit.
상기와 같이 설치된 종래의 부시는 가격이 저렴하나 마모가 쉽게되어 수리 및 교환을 자주 하여야만 하는 문제점과 잦은 수리 및 교환에 따른 작업능율의 저하와 작업시간이 많이 소요되는 문제점이 있었다.The conventional bush installed as described above has a problem in that the price is low but the wear is easy to be frequently repaired and replaced, and the work efficiency is reduced and the work time is required due to frequent repair and replacement.
본 고안은 상기한 제반 문제점을 감안하여 안출한 것으로써, 이의 목적은 부시의 내측에 베어링을 설치하여 축의 회전에 의한 마찰계수를 현저하게 감소시켜 축과 부시의 마모에 따른 파손을 방지하고 또한 마모에 의한 수리 및 교환을 줄여 작업능율을 향상시키며, 작업시간의 단축, 기타 부품의 파손을 방지하는데 있다.The present invention has been devised in view of the above problems, and its purpose is to install a bearing inside the bush to significantly reduce the coefficient of friction due to the rotation of the shaft, thereby preventing damage due to the abrasion of the shaft and the bush, and It improves the work efficiency by reducing the repair and replacement, and shortens the working time and prevents the damage of other parts.
이러한 본 고안의 목적은 부시의 외측에 설치되어 타 부품과의 체결시 부시의 손상을 방지하는 아웃스틸과,내측의 인너스틸과, 축으로부터 회전시충격을 흡수하는 러버와,상기 러버와 인너스틸 사이에 설치되어 축의 회전에 따른 마찰계수를 감소 시키는 볼에 의하여 달성된다.The object of the present invention is installed on the outside of the bush to prevent damage to the bush when fastening with other parts, inner steel of the inner, the rubber to absorb the shock when rotating from the shaft, the rubber and inner steel It is achieved by a ball installed in between to reduce the coefficient of friction according to the rotation of the shaft.

이하 본 고안의 구성 및 작용효과를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation effects of the present invention will be described in detail with reference to the accompanying drawings.
첨부도면 도 2는 본 고안의 일부절결 사시도로서, 이에 따르면 고정체인 하우징(30) 및 베어링(40)과의 체결시 부시(1)의 손상을 방지하는 동시에 체결이 용이하도록 하는 아웃스틸(2)의 내측으로 축(20)으로부터 회전시 충격을 흡수하는 러버(3)가 압착 설치되며 상기 러버(3)의 내측에는 요입홈(4)이 형성된다.2 is a partially cutaway perspective view of the present invention, which prevents damage to the bush 1 when fastening the housing 30 and the bearing 40, which are fixed bodies, and at the same time, facilitates fastening. The rubber 3 that absorbs the shock when rotating from the shaft 20 to the inner side of the rubber press is installed and the recessed groove 4 is formed inside the rubber 3.
또한, 러버(3)의 내측으로는 축(20)과 접하여 부시(1)를 회전시키는 인너스틸(5)이 설치되며 내측의 인너스틸(5)과 러버(3) 사이에 설치되어 축의 회전에 따른 마찰계수를 감소 시키는 볼(6)이 요입홈(4)에 설치된다.In addition, an inner steel 5 for rotating the bush 1 in contact with the shaft 20 is installed inside the rubber 3, and is installed between the inner steel 5 and the rubber 3 in the inner side to rotate the shaft. Ball 6 for reducing the coefficient of friction is installed in the recessed groove (4).
상기와 같이 구성된 본 고안은 축(20)이 회전하면 상기 축(20)과 접하는 인너스틸(5)도 회전된다. 즉 첨부도면 도3의 (가)에 도시된 바와같이 부시(1)가 고정체인 하우징(30)에 설치되어 있을 때에는 상기 인너스틸(5)은 축(20)과의 공차에 의하여 미끄럼이 일어나게 되며 미끄럼은 회전운동에 의하여 발생된 것이기 때문에 인너스틸(5)을 회전시켜 부시(1)를 회전시키려한다.When the shaft 20 rotates, the present invention configured as described above also rotates the inner steel 5 in contact with the shaft 20. That is, when the bush 1 is installed in the housing 30, which is a fixed body, as shown in (a) of FIG. 3, the inner steel 5 is slid due to the tolerance with the shaft 20. Since the sliding is generated by the rotational movement, the inner steel 5 is rotated to rotate the bush 1.
이때, 요입홈(4)에 매설된 볼에의 하여 회전력은 감소되어 인너스틸만 마모되며 부시가 체결된 하우징은 마모되지 않는다.At this time, the rotational force is reduced by the ball embedded in the concave groove 4, only the inner steel is worn, and the housing to which the bush is fastened is not worn.
또한 첨부도면 도 3의 (나)에 도시된 바와같이 베어링(40)에 설치되어 있을 때에는 상기 인너스틸(5)은 축(20)과의 공차에 의하여 미끄럼이 일어나게 되며 미끄럼은 회전운동에 의하여 발생된 것이기 때문에 인너스틸(5)을 회전시켜 부시(1)를 회전시키려한다.In addition, as shown in (b) of FIG. 3, when the inner steel 5 is installed in the bearing 40, the inner steel 5 is slid due to the tolerance with the shaft 20, and the sliding is generated by the rotational motion. Since the inner steel 5 is rotated, the bush 1 is to be rotated.
이때의 회전은 상술한 전자의 회전보다 고속이며 상기 인너스틸(5)에 의하여 1차적으로 감소된 회전력은 요입홈(4)에 매설된 볼(6)에 의하여 회전력이 2차감소된 상태에서 베어링(40)에 전달된다.At this time, the rotation is higher than the above-mentioned rotation of the former, and the rotational force primarily reduced by the inner steel 5 is reduced in the state in which the rotational force is secondarily reduced by the ball 6 embedded in the recessed groove 4. 40 is passed.
한편 2차감소에 의하여 전달된 회전력은 베어링에 전달되지만 부시에서 극감소된 이유로 베어링에 전달된 회전력은 상대 적으로 작아 베어링을 오랫동안 사용할 수 있는 것이다.On the other hand, the rotational force transmitted by the secondary reduction is transmitted to the bearing, but the rotational force transmitted to the bearing is relatively small for the reason that the bush is extremely reduced, so the bearing can be used for a long time.
이와같이 구성되어 사용되는 본 고안은 부시의 내측에 베어링을 설치하여 축의 회전에 의한 마찰계수를 현저하게 감소시켜 축과 부시의 마모에 따른 파손을 방지하고 또한 마모에 의한 수리 및 교환을 줄여 작업능율을 향상시키며, 작업시간의 단축, 기타 부품의 파손을 방지하는 효과가 있다.The present invention is constructed and used in this way by installing a bearing on the inside of the bush to significantly reduce the coefficient of friction due to the rotation of the shaft to prevent damage caused by the wear of the shaft and bush, and also to reduce the repair and replacement due to wear and reduce the work efficiency It improves and shortens working time and prevents damage to other parts.
