Description
본 발명은 엔진의 기동을 위하여 설치되는 시동전동기의 아마츄어 축에 연결되어 피니언을 구동시키도록 하고, 상기 아마츄어와 피니언의 사이에 동력의 전동력을 향상시키기 위한 유성기어를 설치하는 시동전동기에 있어서, 상기 유성기어의 마찰부위인 내경부와 측면부에 윤활유가 저장될 수 있도록 하는 저장수단을 구비하고 이 저장수단에 저장되는 윤활유에 의하여 상기 유성기어의 회전이 원활하게 되도록 한 시동전동기의 유성기어 윤활장치에 관한 것이다.The present invention is connected to the armature shaft of the starting motor which is installed for starting the engine to drive the pinion, and in the starting motor for installing a planetary gear for improving the electric power of the power between the armature and the pinion, In the planetary gear lubrication apparatus of the starting motor, a lubricating oil is stored in the inner diameter and the side of the friction portion of the planetary gear, and the lubricating oil stored in the storing means makes the rotation of the planetary gear smooth. It is about.
일반적으로 차량의 엔진기동을 위하여 설치되는 시동전동기에는 피니언을 회전시켜 엔진을 기동시키기 위하여 하우징내에 아마츄어와 필드부를 설치하고 이들의 자기작용에 의하여 상기 아마츄어가 강한 회전을 하면서 피니언을 구동시키며 이 피니언이 엔진의 링기어를 회전시켜 엔진을 구동하도록 되어 있었다.In general, a starter motor installed for engine start of a vehicle installs an armature and a field part in a housing to rotate the pinion to start the engine, and drives the pinion while the armature rotates strongly by their action. The engine was driven by rotating the ring gear of the engine.
한편, 현금에 이르러서는 상기 아마츄어의 회전력을 피니언에 원활하게 전달시키고 전달되는 동력을 향상시키기 위하여 상기 아마츄어와 피니언의 사이에 선(Sun)기어와 유성기어(Planet)로 이루어지는 유성기어장치를 구비하고 있으며, 상기 유성기는 상기 선기어의 외주를 따라 회전하면서 피니언으로 동력을 전달하도록 구성되어 있었다.On the other hand, in order to smoothly transmit the rotational force of the amateur to the pinion and to improve the power transmitted to the cash provided with a planetary gear device consisting of a sun gear and a planetary gear (Planet) between the amateur and the pinion The planetary body was configured to transmit power to the pinion while rotating along the outer circumference of the sun gear.
또, 상기와 같은 유성기어장치에 있어서의 유성기어는 그 회전을 원활하게 하기 위하여 이의 내경부에 설치되는 베어링과의 사이 및 측면 마찰부에 윤활유를 공급하고 이 윤활유에 의하여 회전을 원활하게 하면서 마찰에 의한 마모를 방지할 수있도록 하고 있으나, 종래의 유성기어에는 상기 오일이 함유된 베어링이나 메탈부시를 상기 유성기어의 내경부에 설치하여 사용하고 있었기 때문에 상기 베어링과 메탈부시에 함유된 오일이 소모될 경우 상기 윤활작용이 저하되고 이에 따라 마모율이 높게 되는 폐단이 있었으며, 또 상기 유성기어의 측면 마찰부분에서는 윤활작용이 이루어지지 못하고 있었기 때문에 상기 유성기어의 마모율이 높게 되면서 소음이 발생하게 되고, 상기 유성기어의 회전에 저항이 가해지게 되므로 이의 회전력이 저하되면서 시동전동기의 출력을 저하시키게 되는 점등의 문제점이 있었다.In the planetary gear device described above, the planetary gear is supplied with lubricating oil between the bearings provided on the inner diameter of the planetary gear and the side friction portion to smoothly rotate the friction, and smooth the rotation by the lubricating oil. However, since the oil-bearing bearing or the metal bush is installed in the inner diameter of the planetary gear in the conventional planetary gear, oil contained in the bearing and the metal bush is consumed. If the lubrication action is lowered and the wear rate is high accordingly, there is a closed end, and since the lubrication action is not performed in the side friction portion of the planetary gear, the wear rate of the planetary gear becomes high and noise is generated. Since the resistance is applied to the rotation of the planetary gear, The output of the coin synchronization there is a problem of light which degrades.
본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로, 본 발명은 엔진의 기동을 위하여 설치되는 시동전동기의 아마츄어 축에 연결되어 피니언을 구동시키도록 하고, 상기 아마츄어와 피니언의 사이에 동력의 전동력을 향상시키기 위한 유성기어를 설치하는 시동전동기에 있어서, 상기 유성기어의 마찰부위인 내경부와 측면부에 윤활유가 저장될 수 있도록 하는 저장수단을 구비하고 이 저장수단에 저장되는 윤활유에 의하여 상기 유성기어의 회전이 원활하게 되도록 한 시동전동기의 유성기어 윤활장치를 제공하려는 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional problems, and the present invention is connected to the armature shaft of the starting motor which is installed for starting the engine to drive the pinion, and the power between the armature and the pinion In the starting motor for installing a planetary gear for improving the transmission force of the planetary gear, comprising a storage means for storing the lubricating oil in the inner diameter portion and the side surface of the friction portion of the planetary gear and by the lubricating oil stored in the storage means It is to provide a planetary gear lubrication device of the starting motor so that the rotation of the planetary gear smoothly, this will be described in detail based on the accompanying drawings as follows.
