본 고안은 로우터리 기관의 경사판캠과 마찰되는 피스톤 내단면의 마멸을 방지케한 피스톤의 마멸방지장치에 관한 것이다.The present invention relates to a piston anti-wear device that prevented the wear of the piston inner end surface friction with the inclined plate cam of the rotary engine.
종래에는 단순히 경사판캠이 삽입되는 요입부를 형성하여 경사판캠의 회동과 함께 요입부 양측 내단면의 강구에 접면시켜 사용하였는바, 이는 장기 사용시 피스톤 내단면의 요홈이 마멸됨으로서 경사판캠과 피스톤 마찰면과의 간극이 생겨 소음이 발생됨은 물론 특히, 마멸로 인한 피스톤의 상, 하사점에 오차가 커지므로 점차적으로 출력이 저하되는 결함이 있었던 것이다.Conventionally, the inclined plate cam is simply formed by inserting the inclined plate cam into contact with the steel balls of the inner end surfaces of both sides of the inclined plate cam, which is used. As a result of the gap between the noise is generated, as well as the error in the upper and lower dead center of the piston due to abrasion, in particular, the output was gradually reduced.
이에 따라 주기적으로 피스톤 전체를 교체하여 주어야만 하기에 경제적 손실 또한 막대하였던 것이다.As a result, the entire piston had to be replaced periodically, so the economic loss was enormous.
본 고안은 이와같은 종래의 제반결함을 해소하고자 안출된 것으로 피스톤의 요입부 양측 내단면에 경질의 보강금구를 각기 압착하여 통상의 강구를 유설함으로서 피스톤과 경사판캠과의 마찰저항을 최대한 감소시켜 피스톤의 마멸을 방지케 한 것이다.The present invention was devised to solve the above-mentioned general defects, and by squeezing hard reinforcing brackets on both inner end surfaces of the indentation part of the piston, the conventional steel balls were squeezed to reduce the frictional resistance between the piston and the inclined plate cam as much as possible. To prevent wear.
이하 본 고안을 첨부도면을 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
피스톤(1) 요입부(1a)의 양측 내단면(1b)(1b')에 형성된 통사의 강구(4)(4a)삽입용 요홈(2)(2a)에 돌침(3')이 다수 형성된 보강금부(3)(3a)를 각기 압착하여서 된 것이다.Reinforcement in which a large number of protrusions 3 'are formed in the steel balls 4, 4a for insertion of grooves formed in both inner end surfaces 1b and 1b' of the piston 1 recessed part 1a. The gold parts 3 and 3a were pressed together.
도면중 미설명부호 10은 로우터리 기관, 20, 20'는 실린더 30은 폴리, 40은 스플라인 축, 50은 경사판 캠이다.In the drawings, reference numeral 10 denotes a rotary engine, 20, 20 'denotes a cylinder 30 poly, 40 a spline shaft, and 50 an inclined plate cam.
이와같이 구성된 본 고안은 통상의 로우터의 기판(10)의 실린더(20)(20')내에 유삽되는 피스톤(1)을 구성하는 것인데, 상기 로우터의 기판(10)은 모우터(도시없음)로부터 동력이 전달되어 폴리(30) 및 이와 축착된 스플라인 축(40)에 의해 경사판 캠(50)이 회동함에 따라 피스톤(1)이 왕복운동을 하게 되는 바, 경사판캠(50)이 마찰되는 피스톤(1)요입부(1a)의 양측 내단면(1b)(1b') 요홈(2)(2a)에 돌침(3')이 다수 돌설된 경질의 보강금구(3)(3a)를 각기 압착시켜 이에 강구(4)(4a)를 유설함으로서 이 강구(3)(3a)와 경사판캠(50)의 양접면부를 밀접하게 하여 경사판캠(50)의 회동시 강구(4)(4a)가 구름접촉을 하게 되므로 마찰저항을 최대한 줄이게 되어 양측 마찰면의 마멸의 거의 무시될 수 있는 것이다.The present invention configured as described above constitutes a piston 1 inserted into a cylinder 20, 20 ′ of a substrate 10 of a conventional rotor, wherein the substrate 10 of the rotor is powered from a motor (not shown). The piston 1 is reciprocated as the inclined plate cam 50 is rotated by the poly 30 and the spline shaft 40 which is constricted thereto, and thus the piston 1 in which the inclined plate cam 50 is rubbed. 2) Hard reinforcing brackets 3 and 3a each having a plurality of protrusions 3 'protruding from the inner end surfaces 1b and 1b' of the recesses 1a and recessed grooves 2 and 2a, respectively. (4) (4a) is provided so that the steel ball (3) (3a) and the contact surface of the inclined plate cam 50 is in close contact with the steel ball (4) (4a) in contact with the cloud when the inclined plate cam 50 is rotated. Therefore, the frictional resistance is reduced as much as possible so that the wear of both friction surfaces can be almost ignored.
한편 장기 사용시 마찰면이 마모된다 하더라도 피스톤(1) 전체를 교체하지 않고 보강금구(3)(3a) 또는 강구(4)(4a)만을 교체하여 줌으로서 재사용할 수 있어 경제적 손실을 줄일 수 있음은 물론이고 항시 소음이 없이 사용할 수 있는 것이다.On the other hand, even if the friction surface wears in long-term use, it can be reused by replacing only the reinforcing brackets (3) (3a) or steel balls (4) (4a) without replacing the entire piston (1). Of course, you can always use without noise.
따라서 본 고안은 마멸이 거의 없어 장기 사용에 적합하며 설사 마모된다 하더라도 간단한 부품의 교체만으로 재사용이 가능하여 경제적 부담이 없으며 소음이 거의 없는 상태를 유지하여 사용시 소음으로 인한 불쾌감을 해소할 수 있는 매우 실용적인 효과를 제공케 되는 것이다.Therefore, this design is suitable for long-term use because there is almost no abrasion, and even if it is worn down, it can be reused by simply replacing a simple part, so there is no economic burden, and it is very practical to solve the discomfort caused by the noise during use by maintaining a state of almost no noise. Will provide an effect.
