Abstract
[기술분야][Technical Field]
본고안은 사출성형으로 제작하는 합성수지재 기어의 치형구조를 개량한 고안에 관한 것이다.The present invention relates to a design that improves the tooth structure of a synthetic resin gear manufactured by injection molding.
[해결하려고하는 기술적 과제][Technical challenge you are trying to solve]
종래 합성수지재 기어는 정밀 가공상의 어려움으로 인해 합성수지 기어성형시에는 기어치의 간격을 여유있게 제작하여 성형하는 경우가 많으므로 정밀도가 낮아 정밀성이 요구되는 기계부품으로는 사용할 수 없었을 뿐 아니라, 백래쉬가 커서 특히 역회전시 마찰소음이 많이 발생하고 기어치의 마모 또한, 급속히 진행되는등 많은 폐단이 있었다.Due to the difficulty in precision processing, conventional synthetic resin gears are often manufactured by forming a gear gap with sufficient margin when molding synthetic resin gears. Therefore, they cannot be used as mechanical parts that require low precision and large backlash. In particular, there were many closures such as high friction noise and reverse gear wear during reverse rotation.

[고안의 목적][Purpose of designation]
[고안이 속하는 기술분야 및 그 분야의 종래기술]The technical field to which the design belongs and the prior art in the field
본고안은 사출성형으로 제작하는 합성수지재 기어의 치형구조를 개량한 고안에 관한 것이다.The present invention relates to a design that improves the tooth structure of a synthetic resin gear manufactured by injection molding.
종래 사출성형으로 제작하는 합성수지재 기어는 고하중이 걸리지 않는 기계에 많이 사용되고 있고, 또, 대량생산이 가능한 잇점이 있으나 대량 생산을 위한 금형제작시 정밀한 가공을 위해서 대개 1차 시험사출후 몇회에 걸친 수정 설계와 편차가 없도록 가공을 하게 되는데, 기어는 그 구조상 수많은 치형이 형성되어 있으므로 가공시 치형 한개 한개를 가공해야 되는 어려움이 있었다.Synthetic resin gears manufactured by conventional injection molding are widely used in machines that do not take high loads, and there are advantages in that they can be mass-produced, but they are usually used several times after the first injection injection for precise processing during mold manufacturing for mass production. Machining is performed so that there is no deviation from the modified design. Since the gear has a large number of teeth formed in the structure, there was a difficulty in machining one tooth during processing.
따라서, 이러한 가공상의 어려움으로 인해 합성수지 기어성형시에는 기어치의 간격을 여유있게 제작하여 성형하는 경우가 많으므로 정밀도가 낮아 절밀성이 요구되는 기계부품으로는 사용할 수 없었을 뿐 아니라, 백래쉬가 커서 특히 역회전시 마찰소음이 많이 발생하고 기어치의 마모 또한, 급속히 진행되는등 많은 폐단이 있었다.Therefore, due to the difficulty in processing, in the case of synthetic resin gear forming, there are many cases in which the gear tooth spacing is made with sufficient margin, so it was not possible to use it as a machine part requiring low precision and low backlash. Many friction noises occurred during rotation, gear teeth wear, and rapid progress.
[고안이 이루고자 하는 기술적 과제][Technical Challenges to be Done]
본고안은 이와같은 점을 감안하여 안출한 것으로 기어치의 구조를 일측에서 타측으로 갈수록 약간 좁아지는 테이퍼형상으로 구성하여 백래쉬의 간격을 조절할 수 있도록 하므로서 종래의 폐단을 해소한 것인데 이를 첨부도면에 의건 상술하면 다음과 같다.This paper devised in view of such a point, and the gear tooth structure has a taper shape that is slightly narrowed from one side to the other side, so that the interval between backlash can be adjusted, thereby eliminating the conventional closure. Is as follows.
[고안의 구성][Composition of design]
요홈(1)을 사이에 둔 기어치(2)(2′)간의 간격을 동일하게 형성한 통상의 기어(3)에 있어서 기어치(2)(2′)를 일측에서 타측으로 갈수록 점차 가늘어지는 테이퍼형상으로 구성하여서 됨을 특징으로 하는 것이다. 도면중 미설명부호 4는 웜이고, 5는 웜휠이며, 6는 평기어이고, S는기어치(2)(2′) 사이에 형성된 백래쉬이다.In a conventional gear 3 having the same spacing between the gear teeth 2 and 2 'with the groove 1 interposed therebetween, the gear teeth 2 and 2' gradually become thinner from one side to the other side. It is characterized by being configured in a tapered shape. In the drawings, reference numeral 4 denotes a worm, 5 denotes a worm wheel, 6 denotes a spur gear, and S denotes a backlash formed between the gears 2 and 2 '.
[고안의 작용][Operation of design]
이와같이된 본고안은 기어치(2)(2′)의 형상을 일측에서 타측으로 갈수록 점차 가늘어지는 테이퍼형상으로 구성한 것이므로 기어치(2)와 (2′)의 사이에 형성된 요홈(1)의 간격도 테이퍼형상으로 이루어져 제3도에서 보는 바와같이 치형접촉시 좌우위치에 따라 백래쉬(S)의 간격이 달라지게 된다.In this way, since the shape of the gear teeth 2, 2 'is formed in a tapered shape that gradually becomes thinner from one side to the other side, the gap between the groove 1 formed between the gear teeth 2 and 2'. As shown in Fig. 3, the gap between the backlash S is changed according to the left and right positions when the tooth is in contact with the taper shape.
따라서, 웜휠(5)를 제작시에는 웜휠(5) 성형용 금형을 설계대로 제작하여 시험사출하고 시험사출한 웜휠(5)의 백래쉬(S)가 설계대로 나오지 않을 때에는 기어치(2)(2′)를 한개씩 재가공하지 않고 제2도에 나타난 바와같이 웜(4)의 위치를 고정시키고 웜휠(5)을 화살표방향으로 이동시켜 주게되면 테이퍼형상으로 된 기어치(2)(2′)간의 간격에 의해 백래쉬(S) 량을 조정할 수 있게 된다.Accordingly, when the worm wheel 5 is manufactured, a mold for forming the worm wheel 5 is manufactured as designed and tested, and when the backlash S of the worm wheel 5 which has been tested is not produced as designed, the gear teeth 2 and 2 ′) Without reworking one by one, as shown in FIG. 2, the position of the worm 4 is fixed and the worm wheel 5 is moved in the direction of the arrow. The gap between the gear teeth 2 and 2 ′ in the tapered shape is obtained. By this, the amount of backlash S can be adjusted.
이때, 조정에 필요한 이동거리는 극히 미세하므로 금형수정이 웜휠(5)의 면A의 높이를 이동거리 만큼의 높이로 조정하면 종래와 같이 기어치(2)(2′)를 일일히 한개씩 수정가공하지 않고도 대량생산에 임할 수 있게 된다.At this time, the movement distance required for adjustment is extremely fine, so if the mold modification adjusts the height of the surface A of the worm wheel 5 to the height as much as the movement distance, the gear teeth 2, 2 'are not modified one by one as in the prior art. You can work on mass production without it.
또, 제4도에 도시된 평기어(6)에서 백래쉬(S)를 조정함에 있어서는 상부 또는 하부기어중 일측을 고정시키고 타측기어를 화살표 방향으로 이동시켜주면 제5도와 같이 백래쉬(S)량을 조절할 수 있게 되고 이때, 조정에 필요한 이동거리는 미세하므로 금형수정시 면A의 높이를 적정높이로 조정하여 양산에 들어가면 되는 것이다.In addition, in adjusting the backlash S in the spur gear 6 shown in FIG. 4, if one side of the upper or lower gear is fixed and the other gear is moved in the direction of the arrow, the amount of backlash S is increased as shown in FIG. In this case, since the moving distance required for adjustment is minute, the height of the surface A should be adjusted to an appropriate height to enter the mass production when the mold is modified.
[고안의 효과][Effect of design]
이와같이 본고안은 기어치(2)(2′)를 테이퍼형상으로 형상하므로서 기어접촉부의 백래쉬(S)량을 좌우이동으로 조정할 수 있어 합성수지 기어 성형시 제작이 매우 용이하고 백래쉬(S)를 최대한 줄여 제작이 가능하므로 정밀한 기계부품으로 사용할 수 있을 뿐 아니라, 소음발생시 현저히 감소하고 이로인한 마찰손실이 적어 기어의 수명이 연장되며 기어의 대량생산을 용이하게 하는등 그 효과가 매우 크다.In this way, this paper has the shape of the gear teeth (2) (2 ') in a tapered shape, so that the amount of backlash (S) of the gear contact portion can be adjusted left and right, so it is very easy to manufacture when forming a synthetic resin gear, and the backlash (S) is minimized. As it can be manufactured, it can not only be used as a precision machine part, but also greatly reduces when noise is generated and the friction loss is small, thereby extending the life of the gear and facilitating mass production of the gear.
