본 발명은 차동유성기어 감속구조를 이용한 권상기에 관한 것이다.The present invention relates to a hoist using a differential planetary gear reduction structure.

본 발명은 특히, 간단한 구조로 높은 감속비를 얻도록하고 역구동에 대한 제동기능을 효과적으로 수행하는 한편, 별도의 제동장치를 배제한 수동 및 전, 수동 겸용의 권상기를 제공하고자 한다.The present invention, in particular, to achieve a high reduction ratio with a simple structure and to effectively perform the braking function for the reverse drive, while providing a manual, full, manual combined hoisting machine without a separate braking device.

일반적으로 권상기는 중량체의 물건을 들어 올리거나 내리는데 사용되는 장치로서 종래 권상기의 구조는 크게 구동원과 구동원의 회전력을 전달하는 감속장치와, 전달된 회전력으로 체인이나 와이어로프를 감아올리는 감기장치로 구성된다. 상기 감속장치는 출력축의 구동력이 입력축에 직접적인 영향을 주는 구조로서 출력축에 걸리는 과부하 및 역구동력에 대응하기 위한 마찰부재가 제동장치에 설치되어 권상된 중량체의 낙하를 방지시켜 주게 된다. 그러나 상기 마찰부재를 이용한 제동수단은 장기간 사용에 의한 마모와 마찰부재내에 이물질이 유입되거나 습기가 많은 장소 및 온도변화가 급격한 장소에서는 마찰부재와 제동원판 또는 제동드럼 사이가 진공상태가 되어 이들이 서로 협착되는 등 권상기의 원활한 작동에 이상을 초래하게 되는 문제점을 안고 있다. 특히, 마찰제동력의 약화는 작업자의 안전과 직결되는 사안으로서 출력축에 걸리는 과부하 및 역구동력에 안정적으로 대응하는 제동수단이 요구되고 있다.Generally, a hoist is a device used to lift or lower a heavy object. The structure of a conventional hoist includes a reduction device for transmitting a rotational force of a drive source and a drive source, and a winding device for winding a chain or wire rope with the transmitted rotation force. do. The deceleration device is a structure in which the driving force of the output shaft directly affects the input shaft, and a friction member is installed in the braking device to prevent overload and reverse driving force applied to the output shaft to prevent the drop of the lifting weight. However, the braking means using the friction member has a vacuum between the friction member and the braking disc or the braking drum in a place where foreign matter is introduced into the friction member or where there is a lot of moisture or where the temperature change is drastically. There is a problem that causes abnormality in the smooth operation of the hoist. In particular, the weakening of the friction braking force is an issue directly related to the safety of the operator, and a braking means for stably coping with the overload and reverse driving force applied to the output shaft is required.

본 발명은 간단한 구조의 높은 감속비는 물론 역구동에 대한 안정적인 제동기능을 갖는 수동 및 전,수동겸용의 권상기를 제공하고자 한다.The present invention seeks to provide a manual, full- and manual-use hoist that has a simple braking function as well as a stable braking function for reverse driving.

이를 위해 본 발명은 구동부를 전위기어가 적용된 2단의 차동 유성기어 감속장치로 구성하여 고효율의 감속비는 물론 역구동에 대한 효과적인 제동기능을 부여함으로써 안정된 사용을 기대하는 한편, 수동 및 전,수동겸용으로 선택적인 사용이 가능하도록 한다.To this end, the present invention is composed of a two-speed differential planetary gear reduction device to which the potential gear is applied to provide a high efficiency reduction ratio as well as an effective braking function for reverse driving, while expecting stable use. This allows for selective use.

본 발명은 상부후크(50) 및 로드체인이 결합된 하부후크(60)가 구비된 통상의 권상기에 있어서, 측판(10')의 일측 중앙 연장상에 고정태양기어(11)를 형성하고 상기 로드쉬브의 일단에 종동태양기어(21)를 형성하여 이 종동태양기어(21)의 일측을 고정태양기어(11)에 밀착되게 끼워 양쪽 측판(10)(10')에 지지, 결합하며 상기 고정 및 종동태양기어(11)(21)는 선택적으로 기어의 잇수가 다른 전위기어로 가공하여 주되, 상기 잇수차이 만큼 유성기어(31)를 구비하여 그 양측을 캐리어 (30)에 축설하고 이 유성기어(31)를 고정 및 출력태양기어(11)(21)의 외주에 등간격으로 치합, 설치하는 한편, 캐리어(30)의 입력축(32)에 당김체인(41)이 설치된 풀리(40)를 구동입력원으로 결합하여 된 구조이다.In the present invention, in the conventional hoist provided with the upper hook 50 and the lower hook 60 coupled with the rod chain, the fixed sun gear 11 is formed on the central extension of one side of the side plate 10 'and the rod A driven sun gear 21 is formed at one end of the sheave so that one side of the driven sun gear 21 is tightly fitted to the fixed sun gear 11 so as to be supported and coupled to both side plates 10 and 10 '. The driven sun gears 11 and 21 are selectively machined with potential gears having different numbers of gears, provided with planetary gears 31 according to the number of teeth, and both sides thereof are arranged in the carrier 30 and the planetary gears ( 31 is fixed to the outer periphery of the output sun gear 11 and 21 at equal intervals, and the pulley 40 in which the pull chain 41 is installed on the input shaft 32 of the carrier 30 is driven to drive. It is a structure that is joined by a circle.

한편, 도 2 에서와 같이 측판(10)(10')의 상부 선단에 피니언기어(34)가 결합된 모터(M')를 설치하고 캐리어(30)의 일측 외주에 구동기어(33)를 환설하여 이에 상기 피니언기어(34)를 치합하여 된 전, 수동 겸용의 권상기구조도 제공한다.Meanwhile, as shown in FIG. 2, the motor M ′ having the pinion gear 34 coupled to the upper end of the side plates 10 and 10 ′ is installed, and the drive gear 33 is installed on one outer circumference of the carrier 30. Therefore, the pinion gear 34 is also meshed with the former, a manual combined hoisting structure.

도면부호중 (50)은 상부후크 (60)은 로드체인이 결합된 하부후크, (B)는 베어링을 나타낸다.Reference numeral 50 denotes an upper hook 60, a lower hook coupled with a load chain, and (B) a bearing.

본 발명은 일측 입력축(32)에 축설된 풀리(40)의 당김체인(41)을 당겨 주게되면 이 구동에 의해 캐리어(30)가 회전하게 되고 또, 캐리어(30) 내부에 유기적으로 치합, 설치된 로드쉬브(20)가 회전됨으로써 하부후크(60)가 결합된 로드체인이 승강되는 수동의 권상구조이다.According to the present invention, when the pull chain 41 of the pulley 40 arranged on one side of the input shaft 32 is pulled, the carrier 30 rotates by this driving, and organically engages and is installed in the carrier 30. As the rod sheave 20 is rotated, the hoist structure of the manual lifting and lowering of the load chain coupled to the lower hook 60 is provided.

상기한 캐리어(30)의 내측에 수용, 설치된 고정태양기어(11)와 일측 종동태양기어(21)의 치차에는 유성기어(31)의 치차가 고정(11) 및 종동태양기어(21)의 양 치차의 폭을 동시에 수용하며 치합되게 된다. 그리고 태양기어(11)(21)의 둘레에 치합되는 유성기어(31)의 수는 고정 및 종동태양기어(11)(21)의 잇수차 만큼 설치되게 되며 서로 다른 치차를 갖는 고정태양기어(11)와 종동태양기어(21)의 치차가 일치하는 지점에서 유성기어(31)가 동시에 치합되게 되므로 유성기어(31)의 수는 고정 및 태양기어(11)(21)의 잇수차 만큼을 필요로 하게 되며 전위기어로 가공되는 태양기어(11)(21)의 선택은 잇수에 따른 축간거리를 고려하여 고정 및 종동태양기어(11)(21)중 어느 하나를 선택적으로 가공할 수 도 있다.The gears of the planetary gear 31 are fixed to the fixed 11 and the driven sun gear 21 in the gears of the fixed sun gear 11 and the driven sun gear 21 accommodated and installed inside the carrier 30. The width of the gear is simultaneously accommodated. The number of planetary gears 31 engaged around the sun gears 11 and 21 is installed by the number of teeth of the fixed and driven sun gears 11 and 21, and the fixed sun gears 11 having different teeth. ) And the planetary gears 31 are simultaneously engaged at the point where the gears of the driven sun gears 21 coincide with each other. Therefore, the number of the planetary gears 31 requires the number of teeth of the fixed and sun gears 11 and 21. The selection of the sun gear (11) (21) to be processed in the potential gear can be selectively processed either of the fixed and driven sun gear (11) (21) in consideration of the interaxial distance according to the number of teeth.

다시 말하면 캐리어(30)에 설치된 입력축(32)의 구동에 의해 캐리어(30)가 자전하게 되며 이에 의해 유성기어(31)는 고정태양기어(11) 주위로 자전 및 공전하게 된다. 유성기어(31)가 고정태양기어(11)를 한바퀴 공전하게 되면 종동태양기어 (21)는 고정태양기어(11)의 잇수 차만큼 차동감속이 되는 것이다.In other words, the carrier 30 rotates by driving the input shaft 32 installed in the carrier 30, thereby causing the planetary gear 31 to rotate and revolve around the fixed sun gear 11. When the planetary gear 31 revolves around the fixed sun gear 11, the driven sun gear 21 is differentially decelerated by the number of teeth of the fixed sun gear 11.

예컨데, 고정태양기어(11) 및 종동태양기어(21)의 잇수차가 2개일 때 유성기어(31)의 치차는 2개를 설치할 수 있으며 이때 고정태양기어(11)의 잇수를 102매 종동태양기어(21)의 잇수를 100매로 하면 감속비는 100/(100-102)= -50 이 되어 높은 감속비를 얻게 된다.For example, when the number of teeth of the fixed sun gear 11 and the driven sun gear 21 is two, the gears of the planetary gear 31 may have two teeth, and the number of teeth of the fixed sun gear 11 is 102 sheets of driven sun gear. If the number of teeth in (21) is set to 100, the reduction ratio is 100 / (100-102) = -50, thereby obtaining a high reduction ratio.

상기와 같은 감속출력은 종동태양기어(21)와 결합된 로드쉬브(20)를 회전시키게 되며 로드쉬브(20)에 권취된 로드체인은 상기 로드쉬브(20)의 출력 회전방향에 따라 감아 올려지거나 감아 내려지게 되며 이때 하부후크(60)에 중량체가 매달려 있을 경우에는 중량체의 자중에 의해 로드쉬브(20)가 역회전하려고 하나 고정 및 종동태양기어(11)(21)에 치합된 유성기어(31)의 조합으로 인해 로드쉬브(20)의 역구동을 효과적으로 방지되게 된다.The deceleration output as described above rotates the rod sheave 20 coupled with the driven sun gear 21 and the rod chain wound around the rod sheave 20 is wound up according to the output rotation direction of the rod sheave 20 or In this case, when the heavy hook is suspended from the lower hook 60, the load sheave 20 tries to reverse rotation due to the weight of the heavy weight, but the planetary gear engaged with the fixed and driven sun gears 11 and 21 ( Combination of 31) effectively prevents the reverse driving of the rod sheave 20.

한편, 도 2 는 본 발명의 다른 실시예를 도시한 것으로서, 전, 수동 겸용의 권상기를 나타내고 있다.On the other hand, Fig. 2 shows another embodiment of the present invention, and shows a hoisting machine for manual and manual use.

이는 전술한 수동권상기의 감속구조를 그대로 유지한 것이나 다만 모터(M')에 의한 구동원의 입력을 캐리어(30)의 외주연에 형성된 구동기어(33)에 치합되게 하여 전술한 입력축(32)에 의한 수동구동 및 구동원의 입력을 통한 전동의 구동원 입력수단을 동시에 구비하고 있다.This maintains the above-described deceleration structure of the manual hoist as it is, but inputs the drive source by the motor M 'to the drive gear 33 formed on the outer periphery of the carrier 30 to the input shaft 32 described above. And a drive source input means of electric power through manual drive and drive source input.

모터(M)에 의한 권상기의 전동구동은 모터(M)축에 설치된 피니언기어(34)가 캐리어(30) 둘레에 환설된 구동기어(33)에 치합되어 상기 모터(M)를 구동시켜주게 되면 피니언기어(34)의 회전에 의해 캐리어(30)가 회전하게 된다. 이때 캐리어(30)는 상기 구동에 의해 서로 다른 회전비를 갖는 피니언기어(34)과 구동기어(33)와의 회전비에 의해 캐리어(30)가 감속 회전되게 되어 높은 감속비를 얻을 수 있다. 물론, 캐리어(30)의 내측에 유기적으로 치합, 설치된 유성기어(31) 및 고정태양기어 (11) 그리고 로드쉬브(20)와 일체로 형성된 종동태양기어(21)등 일련의 내부구조는 전술한 수동권상기의 구조와 동일한 구동조건을 갖추고 있다.When the electric drive of the hoisting machine by the motor M is driven by the pinion gear 34 installed on the motor M shaft is engaged with the drive gear 33 arranged around the carrier 30 to drive the motor M. The carrier 30 rotates by the rotation of the pinion gear 34. In this case, the carrier 30 may be decelerated and rotated by the rotation ratio between the pinion gear 34 and the drive gear 33 having different rotation ratios by the driving, thereby obtaining a high reduction ratio. Of course, a series of internal structures such as a planetary gear 31 and a fixed sun gear 11 and a driven sun gear 21 formed integrally with the rod sheave 20 are organically engaged and installed inside the carrier 30. It has the same driving conditions as the structure of the manual winding machine.

본 발명은 감속비가 다른 2개의 입력수단 즉, 높은 감속비를 갖는 모터(M)의 전동입력수단와, 풀리(40)에 의한 수동입력수단을 동시에 구비한 구조로서 전동에 의해 중량체를 신속히 들어올린 후 수동조작을 통하여 그 조작을 정밀히 할 수 있다. 또한, 권상기의 선택적인 조작이 가능하고 특히, 전위기어를 적용한 2단의 차동유성기어(31)의 구동구조에 의해 중량체에 의한 구동기어(33)의 역구동이 효과적으로 방지되어 중량물의 낙하로 인한 안전사고의 우려를 해소한다.The present invention is a structure having two input means with different reduction ratios, that is, a motor input means of a motor M having a high reduction ratio and a manual input means by the pulley 40 at the same time. Manual operation can precisely control the operation. In addition, the selective operation of the hoisting machine is possible, and in particular, the drive structure of the differential planetary gear 31 of two stages to which the potential gear is applied prevents the reverse drive of the drive gear 33 by the weight body effectively, resulting in falling of the heavy object. Eliminate concerns about safety accidents.

본 발명은 종동태양기어(21)가 결합된 로드쉬브(20)를 와이어로프를 감을 수 있는 드럼으로 교체하여 설치하게 되면 와이어로프 권상기나 윈치등으로도 매우 유용하게 사용할 수 있다.The present invention can be very useful as a wire rope hoist or winch when installed by replacing the rod sheave 20 coupled to the driven sun gear 21 with a drum that can wind the wire rope.

본 발명은 간단한 구조의 수동 및 전,수동겸용의 권상기를 제공함으로써 2단의 차동유성기어 감속장치를 사용하여 높은 감속비를 얻을 수 있을뿐 아니라 로드쉬브 및 드럼 역구동을 효과적으로 방지하고 또, 마찰부재의 마모로 인한 안전사고의 우려를 해소한다.According to the present invention, by providing a manual, full and manual winding machine having a simple structure, a high reduction ratio can be obtained by using a two-stage differential planetary gear reduction device, and effectively prevents reverse driving of the load sheave and drum, and a friction member. Eliminates the risk of safety accidents caused by wear.
