본 고안은 원동축으로부터 동력을 받아서 피동축으로 전달하는 각종 동력전달기구 및 기초 회전전달장치등에 사용되는 유니버샬 조인트에 관한 것으로, 두 전동축의 중심선이 다양한 각도 (0°-90°각도) 범위내에서 상. 하. 좌. 우로 자유자재로 교차하면서 동력을 전달할 수 있도록 원추형 단부를 가진 두 전동축이 각각 한쌍의 반원형링으로 구성되어 각각 다른 직경을 갖는 2개의 동력전달링으로 상호 연결되어 두 전동축의 중간에 위치하는 회동중심링과 회동핀에 의하여 결합 착설되어 상호 연동되는 것이다.The present invention relates to a universal joint used in various power transmission mechanisms and basic rotary transmission devices which receive power from a driving shaft and transmit it to a driven shaft, and the center lines of the two transmission shafts are in various angles (0 ° -90 ° angle). Prize in Ha. Left. The two transmission shafts with conical ends each consist of a pair of semi-circular rings, which are interconnected by two power transmission rings with different diameters so that they can transfer power freely while intersecting freely. Coupling and installation by the center ring and the rotation pin is to interlock with each other.
종래에도 동력전달을 위하여 이미 잘 알려진 일반적인 유니버샬 조인트등의 각종 전달기구 및 장치가 사용되었으나 이러한 것들은 그 대부분이 두 전동축, 즉 원동축과 피동축의 중심선이 대략 30°각도 이하의 범위 이내에서만 사용이 가능하였던 것이고, 30°각도 이상의 범위에서는 단일의 전달기구나 장치로서는 동력전달이 어려웠던 것이다.Conventionally, various transmission mechanisms and devices, such as general universal joints, which are well known for power transmission, have been used, but most of them are used only when the range between the center lines of two transmission shafts, that is, the primary shaft and the driven shaft, is approximately 30 degrees or less. This was possible, and power transmission was difficult with a single transmission mechanism or apparatus in the range of 30 degrees or more.
따라서, 통상적으로 30°각도 이하에서 사용이 가능한 일반적인 기존의 유니버샬조인트를 사용하여 동력을 전달할 때, 두 전동축의 중심선이 30°각도보다 큰 범위인 경우에는 2-3개의 기존 유니버샬조인트를 사용하거나 별도의 전달 보조기구를 사용하여야 하므로서 전달장치의 구조가 복잡해지고 부피와 크기가 커질 뿐만 아니라, 무게도 무거워지는 등의 문제점이 많고 사용중에 고장이 잦게 되는 등의 문제점이 있었던 것이다.Therefore, when power is transmitted using a general existing universal joint that can be used at an angle of 30 ° or less, when the centerline of the two transmission shafts is in a range larger than 30 °, 2-3 conventional universal joints or Since a separate delivery aid must be used, the structure of the delivery device is complicated, and the volume and size are not only large, the weight is heavy, and there are many problems such as frequent failure during use.
이와같은 종래의 각종 동력전달기구 및 장치는 상기와 같은 문제점으로 인하여 그 사용범위가 한정되어 있어서 급속한 산업발달로 인하여 작은 부피와 가벼운 무게로서 간편하게 동력을 전달할 수 있는 동력전달 기구를 필요로 하는 각종 기초전달기구의 설계에 많은 난점이 있었던 것이다.Such various power transmission mechanisms and apparatuses of the related art have a limited use range due to the above problems, and therefore, various foundations that require power transmission mechanisms that can easily transfer power with small volume and light weight due to rapid industrial development. There were many difficulties in the design of the transmission mechanism.
본 고안은 상술한 바와 같은 종래의 문제점을 해결 보완하여 간단한 구조로서 다양한 범위의 각도(0°-90°)에서 동력전달이 가능한 새로운 구조의 유니버샬 조인트를 제공하고저 함에 고안의 목적이 있는 것으로 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention aims to provide a universal joint of a novel structure capable of transmitting power at various ranges of angles (0 ° -90 °) as a simple structure by complementing and solving the conventional problems as described above. When described in detail by the accompanying drawings as follows.
원추형 단부를 가진 두 전동축(1)(2)을 각각 다른 직경을 갖는 2개의 동력전달링(3)(4)으로 상호 연결 착설하되, 두 전동축(1)(2)의 중간에 위치하도록 회동중심링(5)을 착설하여 각각 한쌍의 반원형링(3-1)(3-2)(4-1)(4-2)으로 구성되어 각각 다른 직경을 갖는 2개의 제1,제2동력전달링(3)(4)을 회동핀(6)(7)으로 결합 착설하므로서 두 전동축(1)(2)의 중심선이 다양한 각도(0°-90°)범위 내에서 상. 하. 좌. 우로 자유자재로 교차하면서 동력을 전달할 수 있도록 구성됨을 특징으로 하는 유니버샬조인트이다.The two transmission shafts (1) (2) with conical ends are interconnected with two power transmission rings (3) (4), each having a different diameter, so that they are located in the middle of the two transmission shafts (1) (2). Two first and second dynamic powers each having a different diameter, each of which is equipped with a pair of semi-circular rings 3-1, 3-2, 4-1 and 4-2 by installing a pivot center ring 5. The center line of the two transmission shafts (1) and (2) is in the range of various angles (0 ° -90 °) by coupling and installing the transmission rings (3) and (4) with the pivot pins (6) and (7). Ha. Left. Universal joint is characterized in that it is configured to transmit power while crossing freely.
첨부도면중 미설명부호 8은 결착핀, 9는 슬라이딩편, 10은 고정링11은 체결공을 각각 나타낸다.In the accompanying drawings, reference numeral 8 denotes a binding pin, 9 a sliding piece, 10 a fixing ring 11, and a fastening hole, respectively.
이와같은 본 고안의 유니버샬조인트가 일측의 전동축(1)으로부터 전달되는 동력을 타측의 전동축(2)으로 전달하는 과정을 첨부도면에 의하여 예를 들어 상세히 설명하면 다음과 같다.Such a universal joint according to the present invention will be described in detail with reference to the process of transferring the power transmitted from the transmission shaft 1 on one side to the transmission shaft 2 on the other side by way of example.
즉, 첨부도면 제6도에 도시된 바와 같이 두 전동축(1)(2)의 중심선이 직각(90°)상태로 교차하여 동력을 전달하는 경우에 수평상태로 도시된 일측의 전동축(1)을 기준으로 타측의 전동축(2)이 90°각도 회전하면 제2동력전달링(4)보다 직경이 작은 제1동력전달링(3)의 반원형링(3-1)(3-2)은 회동중심링(5)에 결착된 회동핀(6)을 중심으로 각 90°도 회전하여 직각상태를 유지하고, 제1동력전달링(3)보다 직경이 큰 제2동력전달링(4)은 회동핀(7)에 의해 결착된 회동중심링(5)과 함께 타측의 전동축(2)쪽으로 45°각도 회전하여서 첨부도면 제6도에 도시된 바와같이 두 전동축(1)(2)이 직각상태를 유지하게 되는 것이다.That is, as shown in FIG. 6 of the accompanying drawings, when the center lines of the two transmission shafts 1 and 2 cross each other at right angles (90 °) to transmit power, the transmission shaft 1 on one side shown in a horizontal state is shown. The semi-circular ring (3-1) (3-2) of the first power transmission ring (3) having a diameter smaller than that of the second power transmission ring (4) when the transmission shaft 2 on the other side rotates by 90 ° Is rotated by 90 ° around the pivot pin 6 attached to the pivot center ring 5 to maintain a right angle, and the second power transmission ring 4 having a diameter larger than that of the first power transmission ring 3. Is rotated by 45 ° toward the other side of the transmission shaft (2) together with the rotation center ring (5) fastened by the rotation pin (7) so that the two transmission shafts (1) (2) as shown in FIG. This is a right angle.
이러한 상태에서 일측의 전동축(1)이 화살표 방향인 시계방향으로 회전하게 되면, 한쌍의 반원형링(4-1)(4-2)으로 구성되어 일직선 상태인 제2동력전달링(4)이 회동핀(7)에 의해 결착된 상태로 45°각도를 이루고 있는 회동중심링(5)의 내주면을 따라서 회전하면서 일측편의 반원형링(4-1)은 전동축(1)과 같은 시계방향으로 회전하고 타측편의 반원형링(4-2)은 전동축(1)과 반대인 역시계방향으로 회전하게 되는 것이다.In this state, when one side of the electric shaft 1 is rotated clockwise in the direction of the arrow, a pair of semi-circular rings (4-1) (4-2) consisting of a second power transmission ring 4 in a straight state is The semicircular ring 4-1 on one side rotates in the same clockwise direction as the electric shaft 1, while rotating along the inner circumferential surface of the rotation center ring 5 at a 45 ° angle with the pivot pin 7 engaged. And the semi-circular ring (4-2) of the other side is to rotate in the direction of the system opposite to the transmission shaft (1).
또한, 역시 한쌍의 반원형링(3-1)(3-2)으로 구성되어 직각 상태인 제1동력전달링(3)도 회동핀(6)에 의해 결착된 상태로 45°각도를 이루고 있는 회동중심링(5)의 내주면을 따라서 회전하면서 일측편의 반원형링(3-1)은 전동축(1)과 같은 시계방향으로 회전하고 타측편의 반원형링(3-2)은 전동축(1)과 반대인 역시계 방향으로 회전하게 되므로서 각각 다른 직경을 갖는 제1 및 제2 동력전달링(3)(4)에 의하여 연결 착설된 타측의 전동축(2)은 역시계방향으로 회전하면서 일측의 전동축(1)으로부터 전달받은 동력을 전달하게 되는 것이다.In addition, the first power transmission ring 3, which is also composed of a pair of semi-circular rings (3-1) (3-2) and is perpendicular to each other, is also rotated at a 45 ° angle in a state of being bound by the pivot pin (6). While rotating along the inner circumferential surface of the center ring 5, the semicircular ring 3-1 on one side rotates in the clockwise direction as the transmission shaft 1, and the semi-circular ring 3-2 on the other side is connected to the transmission shaft 1. As the opposite side rotates in the direction of the system, the other transmission shaft 2 installed by the first and second power transmission rings 3 and 4 having different diameters respectively rotates in the direction of the system. It is to transfer the power received from the transmission shaft (1).
상술한 바와 같은 본 고안의 유니버샬 조인트는 두 전동축(1)(2)의 원추형 단부에 각각 관통 삽착된 한쌍의 반원형링(3-1)(3-2)(4-1)(4-2)이 회동핀(6)(7)에 의하여 두 전동축(1)(2) 중간에 위치한 회동중심링(5)과 상호 결합되어 연동되는 제1 및 제2 동력전달링(3)(4)이 두 전동축(1)(2)의 중심선이 다양한 각도(0°-90°)를 이루더라도 원활하게 상호 연동되어 회동하면서 동력을 전달하는 것으로, 그 구조가 간단하여 고장의 염려가 없으며 원활한 회동작동에 의하여 각종 동력전달장치 및 기초 회전전달장치 등에 폭넓고 유용하게 사용될 수 있는 것이다.The universal joint of the present invention as described above has a pair of semi-circular rings (3-1) (3-2) (4-1) (4-2) respectively inserted through the conical ends of the two transmission shafts (1) (2). The first and second power transmission ring (3) (4), which is coupled to and interlocked with the rotation center ring (5) located between the two transmission shafts (1) (2) by the rotation pins (6) and (7). Even if the center lines of these two transmission shafts (1) and (2) form various angles (0 ° -90 °), they are smoothly interlocked and rotated to transfer power.The structure is simple, so there is no risk of failure and smooth rotation. By operation, it can be widely and usefully used for various power transmission devices and basic rotary transmission devices.
