Description
본 발명은 교체가 가능한 예초기의 베어링유닛에 관한 것으로서, 좀더 상세하게 설명하면 예초기의 제조시 칼날하부고정구와 베어링을 결합함에 있어서 충격을 가하지 않도록 함으로서 베어링 유닛에 손상을 주지않고, 전문가가 아니라 하더라도 손쉽게 베어링의 수리 및 교체를 가능하게 함으로써 비용의 절감과 작업의 편리성을 도모하기 위한 예초기의 베어링유닛에 관한 것이다.The present invention relates to a replaceable mower bearing unit, which will be described in more detail, so as not to damage the bearing unit by not impacting the blade lower fixture and the bearing during manufacture of the mower, without the need for an expert. The present invention relates to a bearing unit of a lawn mower for enabling a repair and replacement of a bearing to reduce costs and facilitate operation.
일반적으로 예초기는 잡초를 제거하거나, 성묘시 벌초 작업을 할 때 잡초를 적은 힘으로 많은 량을 제거하기 위한 장치이다. 상기 예초기는 동력장치로 예초칼날을 회전시킴으로써 짧은 시간에 많은 면적의 잡초나 넝쿨들을 베어낼 수 있다. 그러나 칼날이 고속회전 하다 보니 칼날의 안정적인 회전과 내구성을 위해 칼날의 칼날과 플레이트 사이에는 베어링이 설치된다.In general, the mower is a device for removing a large amount of weeds with a small force when weeding, or when working with weeds during the sacred grave. The mower can cut a large area of weeds or vines in a short time by rotating the mowing blade with the power unit. However, as the blade rotates at high speed, a bearing is installed between the blade and the plate for stable rotation and durability of the blade.
베어링 유닛이라 함은 상기 베어링을 고정시키고 보호하기 위한 부품전체를 의미하는데, 대개 도 1에 도시된 바와 같이 종래의 베어링 유닛(1)은 예초칼날(A)의 하부를 고정하고 베어링의 내륜에 끼워지되 하단이 바깥쪽으로 절곡되어 걸림턱(14a)를 형성함으로써 베어링의 내륜에 끼워져 고정되는 칼날하부고정구(14)와, 내륜과 외륜으로 이루어지는 베어링(12)과, 상기 베어링(12)을 보호플레이트(B)에 고정시키기 위한 베어링 고정구(13)로 이루어진다.The bearing unit means an entire part for fixing and protecting the bearing. As shown in FIG. 1, the conventional bearing unit 1 fixes the lower part of the mowing blade A and fits the inner ring of the bearing. But the lower end is bent outward to form a locking step (14a), the lower blade fixing fixture 14 which is fitted and fixed to the inner ring of the bearing, the bearing 12 consisting of the inner ring and the outer ring, and the bearing 12 protects the plate ( It consists of a bearing fixture 13 for fixing to B).
상기한 종래 예초기용 베어링 유닛의 결합은 칼날하부고정구가 베어링 고정구를 사이에 두고 베어링의 내륜에 끼워진 다음 상기 칼날하부고정구의 하단이 프레싱 타격에 의해 바깥쪽으로 벌어지면서 베어링 내륜의 하단에 걸리도록 하는 방법을 사용하게 된다.The combination of the conventional mowing bearing unit is such that the blade lower fixture is fitted to the inner ring of the bearing with the bearing fixture therebetween, and then the lower edge of the blade lower fixture is caught on the lower end of the bearing inner ring while being pushed outward by a pressing strike. Will be used.
즉 이처럼 벌어진 칼날하부고정구의 하단은 베어링 내륜 하단에 걸림턱으로 작용하게 되어 베어링으로 부터 분리되지 않게 되는 것이다.In other words, the lower edge of the blade lower fasteners thus opened acts as a locking jaw at the lower end of the bearing inner ring so that it is not separated from the bearing.
그러나 이처럼 베어링 내륜 하단에 강제적으로 바깥쪽으로 프레싱되어 결합된 칼날하부고정구는 쉽게 빠지지 않는 상태가 되어 베어링 유닛, 즉 칼날하부고정구와 베어링 고정구, 베어링 중 어느 하나의 부품이 손상되어 교체의 필요성이 있다고 하더라도 모두 폐기시켜야 하고 새 제품을 사용해야 하는 등의 경제적 부담이 큰 단점을 갖는다.However, the lower blade fastener coupled to the lower end of the bearing inner force forced outwards does not easily fall out, so even if any part of the bearing unit, that is, the lower blade fastener, the bearing fixture, or the bearing is damaged and needs to be replaced, The economic burden of having to dispose of them all and using new products is a big disadvantage.
심지어는 예초 작업 중 베어링에 노끈 또는 이물질이 들어가 칼날이 회전되지 않는 경우는 베어링 내부의 노끈 및 이물질만 제거해도 사용할 수 있음에도 불구하고 종래의 베어링 유닛을 사용이 불가하여 폐기시켜야만 하고, 대개 벌초 등 깊은 산중에서 많은 예초작업이 이루어지는데 이 경우에도 작업을 중단하고 먼길을 내려왔다가 수리해서 다시 작업하러 가야 하는 등 엄청난 불편함을 수반하는 단점을 갖는다.Even in the case of mowing, if the rope does not rotate due to a string or foreign substance entering the bearing, the conventional bearing unit cannot be used even though only the string and the foreign substance inside the bearing can be removed. A lot of mowing work is done in the mountains, but even in this case, there are disadvantages that entail tremendous inconvenience, such as stopping work, going down a long road, and repairing and going to work again.
특히 예초기는 한정된 기간 동안만 집중적으로 사용하고 미 사용시에는 장시간 보관해야 하는데, 종래의 베어링 유닛은 분리가 불가능해 기름칠 및 소제 등과 같은 관리가 어려워 내구성이 현저히 떨어지고 성능이 저하되는 등의 단점을 갖는 것이다.In particular, mowers should be used intensively for a limited period of time and stored for a long time when not in use. Conventional bearing units are difficult to separate, which makes them difficult to manage such as oiling and cleaning. .
또한 종래 베어링 유닛은 칼날하부고정구를 베어링에 고정시킴에 있어 칼날하부고정구의 하단에 정교하지 못한 프레싱방식에 의해 강한 충격을 가해 바깥쪽으로 칼날하부고정구의 하단을 벌리는 방법을 사용함으로써 필연적으로 베어링과 베어링 유닛, 기판 등에 충격을 주어 미세한 손상 및 뒤틀림이 발생하는 등의 단점을 갖는 것이다.In addition, the conventional bearing unit inevitably fixes the lower blade fastener to the bearing by applying a strong impact to the lower edge of the lower blade fastener by an uneven pressing method, thereby inevitably spreading the lower edge of the lower blade fastener to the outside. Impact on the unit, the substrate, etc. will have the disadvantage of generating fine damage and distortion.
상기와 같은 목적을 달성하기 위하여 본 발명은 칼날의 하부를 고정하고 베어링의 내륜에 끼워져 고정되는 칼날하부고정구와, 내륜과 외륜으로 이루어지는 베어링과, 상기 베어링을 보호플레이트에 고정시키기 위한 베어링 고정구로 이루어 지는 예초기용 베어링 유닛에 있어서, In order to achieve the above object, the present invention consists of a lower blade fastener fixed to the lower portion of the blade and fitted into the inner ring of the bearing, a bearing consisting of an inner ring and an outer ring, and a bearing fixture for fixing the bearing to the protective plate. In the bearing unit for losing mowers,
상기 칼날하부고정구의 외주면 하부에 오목홈을 형성하고, 상기 오목홈에는 슬립링이 삽입되도록 하되, 상기 슬립링의 상단이 베어링 내륜의 하단에 걸리도록 구성됨을 특징으로 한다.A concave groove is formed in a lower portion of the outer peripheral surface of the lower blade fixing fixture, and the slip ring is inserted into the concave groove, but the upper end of the slip ring is configured to be caught by the lower end of the bearing inner ring.
칼날하부고정구와 베어링, 베어링 고정구로 이루어지는 베어링 유닛이 분리가 거의 불가능하게 결합된 종래의 베어링 유닛과는 달리 본 발명 베어링 유닛은 손쉽게 분리가 가능하게 되어 전문가가 아니더라도 작업자 스스로 손쉬운 교체수리가 가능하게 되고, 또 베어링 유닛 중에서도 손상된 부품만의 교체가 가능하여 유지비용의 절감이 가능하다. Unlike conventional bearing units in which a bearing unit consisting of a lower blade fastener, a bearing, and a bearing fixture is almost impossible to be separated, the bearing unit of the present invention is easily detachable, so that an operator can easily replace and repair the product. In addition, it is possible to replace only the damaged parts in the bearing unit, thereby reducing the maintenance cost.
또한 베어링에 노끈이나 이물질이 끼어 회전이 불가한 경우는 작업현장에서 수리가 가능하며, 필요한 부품을 준비되어 있다면 베어링유닛이 손상되었다고 하더라도 현장에서 고장난 부품만의 교체가 가능하게 되어 작업을 중단하고 먼길을 내려왔다가 수리해서 다시 올라가지 않아도 되는 등 예초작업을 해본 사람들만 알 수 있는 엄청난 작업의 편리성을 도모할 수 있는 것이다.In addition, if the rope cannot be rotated because of a string or foreign substance in the bearing, it can be repaired at the work site.If the necessary parts are prepared, even if the bearing unit is damaged, only the failed parts can be replaced in the field, so the work is stopped for a long time. It is possible to promote the convenience of enormous work that only those who have worked on mowing, such as not having to come down and repair and go up again.
또 프레싱방식에 의해 고정되는 종래의 베어링 유닛에 비해 본 발명 베어링 유닛은 부품에 전혀 충격을 가하지 않게 되어 내구성과 제품 수명의 증대, 고장의 최소화 등이 가능한 효과를 갖는다. In addition, compared with the conventional bearing unit fixed by the pressing method, the bearing unit of the present invention has no effect on the parts at all, and has the effect of increasing durability, product life, minimizing failure, and the like.
또 예초기를 사용하지 않을 때에는 베어링 유닛을 분리하여 기름칠을 해놓는 등 세심한 관리가 가능하게 되어 내구성의 향상 및 안정적인 작동이 가능한 효과를 갖는다.In addition, when not using the mower, the bearing unit can be separated and oiled for careful management, thereby improving durability and enabling stable operation.
또한 본 발명은 베어링 유닛의 분리 판매가 가능하게 되는 등 소비자의 유익에 도움이 되며, 전세계에 전례 없는 예초기 분야의 아이디어로 예초기의 수출 촉진 등에도 이바지할 수 있는 매우 유용한 발명인 것이다.In addition, the present invention is useful for the benefit of the consumer, such as the separate sale of the bearing unit, it is a very useful invention that can contribute to the promotion of the export of the lawn mower as an idea in the field of mowers unprecedented worldwide.

이에 본 발명의 구성을 첨부된 도면에 의하여 당업자가 용이하게 이해하고 재현할 수 있도록 상세하게 설명하면 다음과 같다.Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.
본 발명은 예초칼날의 하부를 고정하고 베어링의 내륜에 끼워져 고정되는 칼날하부고정구(140)와, 내륜(121)과 외륜(122)으로 이루어지는 베어링(120)과, 상기 베어링(120)을 보호플레이트에 고정시키기 위한 베어링 고정구(130)로 이루어 지는 예초기용 베어링 유닛에 있어서, The present invention is fixed to the lower edge of the mowing blade, the lower blade fixing fixture 140 is fixed to the inner ring of the bearing, the bearing 120 consisting of the inner ring 121 and the outer ring 122, and the bearing 120 to protect the plate In the lawn mower bearing unit consisting of a bearing fixture 130 for fixing to the
상기 칼날하부고정구(140)의 외주면 하부에 오목홈(140a)을 형성하고, 상기 오목홈(140a)에는 슬립링(150)이 삽입되도록 하되, 상기 슬립링(150)의 상단이 베어링 내륜(121)의 하단에 걸리도록 구성된다.Concave groove (140a) is formed in the lower outer peripheral surface of the lower blade fixing fixture 140, and the slip ring 150 is inserted into the concave groove (140a), the upper end of the slip ring 150 is the bearing inner ring 121 It is configured to be caught at the bottom of the).
이때 칼날하부고정구(140)의 하부라 함은 베어링(120)의 내륜을 관통하여 돌출된 부분을 의미하며, 따라서 상기 베어링(120)의 내륜을 관통하여 돌출된 부분의 외주면에 오목홈(140a)이 형성되어진다.In this case, the lower portion of the lower blade fixing tool 140 refers to a portion protruding through the inner ring of the bearing 120, and thus, a concave groove 140a on the outer circumferential surface of the portion protruding through the inner ring of the bearing 120. Is formed.
이는 상기 오목홈(140a)의 위치에 의해 슬립링(150)이 끼워졌을 때 상기 슬립링(150)의 상단이 베어링 내륜(121)의 하단에 긴민하게 밀착된 상태로 걸릴 수 있기 때문이다.This is because when the slip ring 150 is fitted by the position of the concave groove 140a, the upper end of the slip ring 150 may be caught in a close contact with the lower end of the bearing inner ring 121.
이처럼 슬립링(150)의 상단이 베어링 내륜(121)의 하단에 긴밀하게 밀착된 상태로 걸려야 하는 이유는 예초칼날(A)의 하부를 볼트에 의해 고정하고 있는 칼날하부고정구(140)가 베어링(120)과 이격될 경우 예초칼날(A)의 회전이 안정적이지 못하기 때문이다.The reason why the upper end of the slip ring 150 is in close contact with the lower end of the bearing inner ring 121 is that the lower blade fixing fixture 140 is fixed to the lower blade of the mowing blade A by a bolt. This is because the rotation of the mowing blade (A) is not stable when spaced apart from 120).
상기 슬립링(150)은 원형의 형상을 가지며, 양단에는 공구를 넣어 벌리기 용이하도록 공구삽입공(151)이 형성되어져 있다.The slip ring 150 has a circular shape, and a tool insertion hole 151 is formed at both ends so as to easily open the tool.
따라서 본 발명은 베어링(120)의 외륜(122)을 베어링 고정구(130)에 의해 보호플레이트(B)에 고정시킨 상태에서 예초칼날(A)이 베어링(120)의 내륜(121)에 지지된 상태로 원활한 회전이 가능하게 된다.Therefore, in the present invention, the cutting blade A is supported on the inner ring 121 of the bearing 120 in a state in which the outer ring 122 of the bearing 120 is fixed to the protective plate B by the bearing fixture 130. Smooth rotation is possible.
이처럼 본 발명은 칼날하부고정구(140)가 슬립링(150)에 의해 베어링 내륜(121)에 걸려 빠지지 않는 상태가 되며, 상기 슬립링(150)만 필요에 의해 분리하게 되면 모든 베어링 유닛이 분리가능하게 되어 부품의 교체 및 수리 등이 용이하게 되는 것이다.As such, the present invention is in the state that the lower blade fixing fixture 140 is not caught in the bearing inner ring 121 by the slip ring 150, all the bearing units can be separated if only the slip ring 150 is separated as necessary. It will be easy to replace and repair parts.
이처럼 상기한 구성을 갖는 본 발명이 비록 한정된 실시예에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능하다 할 것이다.Although the present invention having the above-described configuration has been described by means of a limited embodiment, the present invention is not limited by this and the technical spirit of the present invention and the following by those skilled in the art to which the present invention pertains. Various modifications and variations will be possible within the scope of the appended claims.
