Description

조립 구조를 갖는 선회 베어링 기어{rotation bearing gear structure for assembly}Rotating bearing gear structure for assembly

본 고안은 건설기계의 선회장치 다수가 내치 기어로 제작되어있어 사용후 폐기되어지는 내치 기어를 외치 기어로 개조하여 재사용 할수 있도록 고안된것으로 보다 상세히는 탈착 가능한 선회 장치가 구비된 선회베어링 기어에 관한 것이다.The present invention is designed to reuse the internal gears that are discarded after use because many of the turning devices of construction machinery are made of internal gears. More specifically, the present invention relates to a rotating bearing gear having a removable rotating device. .

종래의 선회 장치는 굴삭기의 하부 프레임에 고정하는 내부 링기어의 외 측면에볼(110)을 가진 스윙 베어링을 설치하고, 그스윙 베어링 위에 상체가 장착되는 상부 프레임을 고정하여 선회모터 축의 피니언 기어가 링기어에의해 회동함에 따라 스윙 베어링에서 상체가 선회 하도록 되어있으나, 고가로 제작되며 구조가 복잡하고 선회베어링 볼의 마모성이 커서 고장율이 많고 또 교체시 부품 전체를 신품으로 교체하여야 하므로 이용상 비경제적인 결함이 가장 많이 발생하게 된다.Conventional turning device is installed on the outer side of the inner ring gear fixed to the lower frame of the excavator with a ball bearing (110), and the upper frame is mounted on the swing bearing pinion gear of the swing motor shaft The upper body is to swing in the swing bearing as it is rotated by the ring gear, but it is expensive and the structure is complicated and the abrasion of the swing bearing ball is large, so it has a high failure rate and the whole part needs to be replaced with a new one. This happens most often.

다시 말하면 볼(110)의 일부분의 마모 및 파손시에도 선회 장치(100) 전체를 폐기하영야 하는 낭비가 되고, 또 공사 현장에서는 선회 장치(100)의 교환이 용이하지 않는바 이를 위하여 제작 공장으로 이동하여야 하는 문제점도 있어 공기 지연 및 비용의 낭비를 초래하였다.In other words, even when a part of the ball 110 is worn and damaged, the entire turning device 100 must be discarded, and the construction of the turning device 100 is not easy at the construction site. There is also a problem that must be moved, resulting in air delays and waste of money.

선회 장치 전체가 일체형으로 문제발생시 전체를 교환하여야 한다.The whole turning device is integral and the whole should be replaced.

선회 장치 전체를 일체형으로 제작하디 않고 조립형으로 제작하여 작업의 간소화를 하며, 마모 및 고장의 발생 되는 부위만을 탈착 가능하도록 조립형으로 제공한다.The whole swivel device is manufactured as an integrated type instead of an integrated one, simplifying the work, and providing the assembled type so that only the part where the wear and failure occurs can be detached.

고장이 발생된 부분만 교환으로 인하여 경비의 지출을 최소화하여 경제성을 추구함.Exchanging only the parts where failure occurs, minimizing expenses and pursuing economic feasibility.

기존 건설 기계의 선회 장치의 다수가 내치 기어로 제작되어 있어 사용후 폐기되어지는 내치 기어를 외치 기어로 개조하여 재 사용 할수 있도록 고안 된것이다.Since many of the turning devices of existing construction machines are made of internal gears, they are designed to be reused by converting internal gears that are discarded after use into external gears.

내치 기어(220)에 분활된 스퍼어 기어(210)을 볼트(230), 너트(240)로 조립하여 외치 조립 구조를 갖는 선회 베어링 기어로 재 생산 되어 수많은 건설 기계 및 항타기의 부속품으로 사용 되어 질수 있어 경제적 으로는 좋은 활용 가치가 있을 것으로 판단 되어 진다. The spur gear 210 divided by the inner tooth gear 220 is assembled with the bolt 230 and the nut 240 to be re-produced as a slewing bearing gear having an outer tooth assembly structure, which can be used as an accessory for a number of construction machinery and riders. Therefore, it is considered to be of good economic value.
