Abstract

The present invention provides a cam follower including a high-rigidity shaft and a cylinder coupled to one end of the shaft, thereby needing no needle bearing. An expansion support protrusion, which extends in a perpendicular direction from the outer circumference of the high-rigidity shaft, is formed at the end of a cylindrical coupling part of the high-rigidity shaft, and is coupled to a first coupling part formed on the outer side of a central hole of the cylinder. A cylindrical coupling shaft is formed inwardly of a round support protrusion of a shaft bar, and is coupled to a second coupling part formed in the central hole of the cylinder. Round concave grooves are formed in parallel on the surface of the cylindrical coupling shaft at regular intervals so that the surface of the cylindrical coupling shaft formed between the round concave grooves is in close contact with the second coupling part of the cylinder. A supporting bar coupling shaft which has a diameter smaller than that of the coupling shaft is formed on the outer surface of the coupling shaft of the shaft bar such that a support part of the supporting bar is coupled. A fastening nut is screw-coupled to a male screw part formed at an end of the coupling shaft to fix the shaft bar to the supporting bar. A lubricating oil injection hole is formed at the center of the shaft bar, and a lubricating oil supply hole is formed to be continuous from the lubricating oil injection hole of the shaft bar to the cylindrical coupling shaft and the supporting bar coupling shaft. Therefore, the present invention can support a cam mechanism or a linear motion apparatus, which contacts the surface of the cylinder.

Description

캠 플로워{CAM FLOWER}Cam Follower {CAM FLOWER}

본 발명은 캠 플로워의 개량에 관한 발명이다.This invention relates to the improvement of a cam follower.

캠 플로워는 고강성 축봉(1)과 원통(2) 사이에 니들베어링(20)이 개입되어 캠기구 또는 직선운동설비의 중량을 감당하는 베어링으로 이용된다.The cam follower is used as a bearing that bears the weight of a cam mechanism or a linear motion facility with a needle bearing 20 interposed between the high rigidity shaft shaft 1 and the cylinder 2 .

따라서 종래의 캠 플로워는 고강성 축봉에 원통을 결합하고, 원통과 축봉 사이에 니들베어링을 개입하는 구성으로 되어 구조가 복잡하고, 정교하기 때문에 생산비가 높아지는 불편이 있고, 그럼에도 니들베어링이 하중을 크게 부담하므로 손상이 심하여 내구성을 담보할 수 없는 불편이 있었다.Therefore, the conventional cam follower combines a cylinder with a high rigidity shaft and a needle bearing is interposed between the cylinder and the shaft, so the structure is complicated and sophisticated, so the production cost is inconvenient. Because of the burden, the damage was severe and the durability could not be guaranteed.

선행기술 공개특허공보 제10-2018-0112574Prior Art Laid-Open Patent Publication No. 10-2018-0112574

본 발명은 상기 불편을 해소하기 위하여 개발된 것이다.The present invention was developed to solve the above inconvenience.

본 발명은 고강성 축봉과 축봉의 일단에 결합하는 원통으로 이루어져 니들베어링이 필요 없는 캠 플로워를 구성한다.The present invention constitutes a cam follower that does not require a needle bearing because it consists of a high rigidity shaft and a cylinder coupled to one end of the shaft.

이를 위해 본 발명은 고강성 축봉의 원통결합부 끝에 축봉외주에서 직각방향으로 확장되는 확장지지돌부를 형성하여 원통의 중심공 외측에 형성된 제1결합부를 결합하고, 축봉의 환상지지돌부 내측으로 원통결합축을 형성하여 원통중심공에 형성된 제2결합부를 결합하며, 축봉의 원통결합축 표면에 일정간격으로 환상요입홈을 나란히 형성하여 환상요입홈 사이에 형성된 원통결합축 표면이 원통의 제2결합부에 밀착 결합되게 하고, 축봉의 결합축 외측에 결합축 보다 직경이 작은 지지대 결합축을 형성하여, 지지대의 지지부를 결합하고, 결합축끝에 형성한 수나사부에 고정너트를 나사결합하여 지지대에 축봉을 고정시키며, 축봉 중심에 윤활유 주입공을 형성하여 축봉의 윤활유 주입공을 형성하여 축봉의 윤활유 주입공에서 축봉의 원통결합축과 지지대 결합축으로 연통되게 윤활유 공급공을 형성하여서 되는 구성이다.To this end, the present invention forms an extended support protrusion extending in a right angle direction from the outer periphery of the shaft at the end of the cylindrical coupling part of the high-rigidity shaft rod to combine the first coupling part formed on the outside of the central hole of the cylinder, and the cylindrical coupling to the inside of the annular support protrusion of the shaft rod The shaft is formed and the second coupling part formed in the cylindrical center hole is coupled, and annular recessed grooves are formed side by side at regular intervals on the surface of the cylindrical coupling shaft of the shaft so that the surface of the cylindrical coupling shaft formed between the annular recessed grooves is the second coupling part of the cylinder. A support coupling shaft with a smaller diameter than the coupling shaft is formed on the outside of the coupling shaft of the shaft to couple the support of the support, and the fixing nut is screwed to the male threaded part formed at the end of the coupling shaft to fix the shaft to the support. , A lubricating oil injection hole is formed at the center of the shaft to form a lubricating oil injection hole for the shaft, and a lubricating oil supply hole is formed so that the lubricating oil injection hole of the shaft is communicated with the cylindrical coupling shaft of the shaft and the support coupling shaft.

이와 같이 된 본 발명은 고강성 축봉(1)의 원통결합부에 환상지지돌부(1a)와 원통결합축(1b)이 형성되어 원통(2)의 제1결합부(2a)와, 제2결합부(2b)가 끼워지고, 지지대 결합축에 지지대(4)를 결합하면 원통이 축봉의 원통결합부에 결합되어 원통 표면에 접촉하는 캠기구 또는 직선운동 설비를 지지할 수 있게 된다.In the present invention as described above, an annular support protrusion (1a) and a cylindrical coupling shaft (1b) are formed in the cylindrical coupling portion of the high rigidity shaft rod (1), the first coupling portion (2a) of the cylinder (2) and the second coupling The part 2b is fitted, and when the support 4 is coupled to the support coupling shaft, the cylinder is coupled to the cylindrical coupling part of the shaft rod to support the cam mechanism or the linear motion facility in contact with the cylindrical surface.

따라서 본 발명은 원통의 제1결합부와 제2결합부에 축봉의 환상지지돌부(1a)와 원통결합축(1b)이 결합하여 원통(2)이 축봉에서 제자리 회전을 하게 되고, 특히 원통결합축 표면에 형성된 환상요입홈에 윤활유가 공급되므로, 원통결합축에 윤활유가 공급되어 니들베어링을 사용하지 않아도 원통이 지지되는 원통베어링을 구성할 수 있기 때문에 캠 기구를 충분히 지지하고, 안내하는 캠 플러워를 형성할 수 있게 되어 견고하고 내구적인 캠 플로워를 구성할 수 있으며, 이로인해 저렴하면서 내구적인 캠 플러워를 공급할 수 있는 이점을 얻을 수 있다.Therefore, in the present invention, the annular support protrusion 1a and the cylindrical coupling shaft 1b of the shaft are coupled to the first coupling part and the second coupling part of the cylinder so that the cylinder 2 rotates in place on the shaft rod, in particular, the cylindrical coupling Since lubricating oil is supplied to the annular concave groove formed on the shaft surface, lubricating oil is supplied to the cylindrical coupling shaft, and a cylindrical bearing in which a cylinder is supported can be formed without using a needle bearing. The cam follower can be formed to form a strong and durable cam follower.
