본 고안은 프레스 성형과 주형을 혼합하여 심체드럼과 외륜을 일체로 형성한 풀리에 관한 것이다.The present invention relates to a pulley in which a core drum and an outer ring are integrally formed by mixing press molding and a mold.
통상의 풀리는 전체를 주물로 성형하거나 또는 철판을 단계적으로 프레스 성형하는 방식으로 제작되고 있다.Ordinary pulleys are manufactured by molding the whole as a casting or by step forming a steel sheet.
전자의 경우 견고하기는 하나 중량의 무겁고 제작원가가 높으며, 후자의 경우 프레스 성형과정에서 철판의 절곡부위에 크랙이 발생하여 장기간 사용하면 외륜부분이 갈라지는 현상이 발생한다.In the former case, the weight is heavy but the manufacturing cost is high. In the latter case, cracks are generated at the bent part of the steel plate during the press molding process, and the outer ring part is cracked when used for a long time.
본 고안은 이러한 점에 착안하여 가볍고 제작원가가 저렴하며 외륜의 수명을 장기간 보장할 수 있는 풀리를 제공하는데 목적을 두고 있다.The present invention aims at providing a pulley that is light in weight, inexpensive to manufacture, and which can guarantee a long life of the outer ring.
본 고안의 구조를 첨부한 도면에 따라 상세히 설명하면 다음과 같다.The structure of the present invention will be described in detail with reference to the accompanying drawings.
풀리의 심체드럼(2)의 주연부를 절곡하여 절곡부(3)를 형성하고 절곡부(3)에 다수의 관통공(4)(4') 및 걸림턱(5)(5')을 타발하는 한편, 절곡부(3)의 둘레에 외륜(1)을 일체로 주물성형한 구조이다.Bending the periphery of the core drum (2) of the pulley to form a bent portion (3) and punching a plurality of through holes (4) (4 ') and locking jaw (5) (5') in the bent portion (3) On the other hand, the outer ring 1 is integrally cast around the bent portion 3.
미설명 부호(6)는 나사결합공이다.Reference numeral 6 is a screwing hole.
본 고안은 벨트를 작동시키는 외륜(1)만을 주물로 성형하므로 벨트와 접하는 부분이 견고하며, 나머지 부분은 철판으로 프레스 성형하므로 전체적으로 중량이 가볍고 제작단가가 낮다.The present invention is formed by casting only the outer ring (1) to operate the belt is a part in contact with the belt is solid, the remaining part is press-molded by iron plate, so the overall weight is light and the manufacturing cost is low.
본 고안의 심체드럼(2)의 주연부를 절곡하여 절곡부(3)를 형성한 것은 외륜(1)이 벨트 3개분의 폭을 가지므로 외륜(1)의 폭과 부합하는 정도의 폭을 절곡부(3)로 형성해야 하기 때문이다.The bending part 3 is formed by bending the periphery of the core drum 2 of the present invention, since the outer ring 1 has a width of three belts, the bent part has a width corresponding to the width of the outer ring 1. It is because it should form as (3).
절곡부(3)에 형성된 관통공(4)(4')과 걸림턱(5)(5')은 그 위치나 형상, 그리고 숫자에는 크게 구애되지 아니하며 심체드럼(2)과 외륜(1)이 주물성형시 일체로 견고하게 융합되어 사용중 서로 이탈되지 아니하도록 작용한다.The through-holes 4, 4 'and the locking jaws 5, 5' formed in the bent portion 3 are not particularly limited in position, shape, and number, and the core drum 2 and the outer ring 1 are When casting, it is firmly fused in one piece so that it does not deviate from each other during use.
다시말하면, 절곡부(3)에 형성된 다수의 관통공(4)(4')과 걸림턱(5)(5')은 외륜(1)을 주물성형할 때 용해된 주철로 채워져 심체드럼(2)이 회전되어도 외륜(1)이 심체드럼(2)의 절곡부(3)에 견고히 용착되어 이완이나 유격이 발생하지 아니한다.In other words, the plurality of through holes 4, 4 ′ and the locking jaw 5, 5 ′ formed in the bent portion 3 are filled with molten cast iron when the outer ring 1 is cast and filled with the core drum 2. ), The outer ring (1) is firmly welded to the bent portion (3) of the core drum (2) does not cause any relaxation or play even if the rotation.
본 고안은 철판을 프레스로 성형하여 심체드럼(2)만을 1차로 간단히 제작할 수 있으며 그 다음 프레스 성형된 심체드럼(2)을 주형에 넣어 외륜(1)을 주물로 성형하는 것이므로 내구성에 있어서는 주물풀리와 같고 중량면에 있어서는 주물풀리보다 월등히 가벼우며, 제작원가에 있어서는 프레스 성형풀리나 주물풀리보다 저렴한 편익을 가진다.The present invention can be produced by simply pressing the iron plate by pressing the core body (2) as a primary, and then put the press-formed core drum (2) in a mold to form the outer ring (1) as a casting, so in terms of durability In terms of weight, it is much lighter than the casting pulley, and in manufacturing cost, it has a lower cost than the press molding pulley or the casting pulley.
