연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

The present invention provides a balance load actuator for effecting motion between a first part and a second part. An embodiment of the present invention comprises a main housing; a shaft; a motion transfer assembly; and a load balancing assembly. The balance load actuator receives substantial external loads through a load balance assembly and distributes the loads to the main housing, thus relieving undue stress otherwise exerted on the shaft and enabling lighter and smaller design components and construct.

An apparatus for effecting movement of a movable member relative to a structural member, the apparatus comprising:a main housing; a motion transfer assembly mechanically associated with the housing; the motion transfer assembly including a shaft; a load balancing assembly mechanically associated with the housing for receiving a load and distributing it directly to the main housing; and a rod end having an eye, a foot, and a shank, the foot of the rod end mechanically associated with the shaft; the load balancing assembly including: a spring housing having a base; a spring having one end and a distal end, the one end affixed to the base of the spring housing; and an end cap with an inside diameter and a beveled edge; wherein the shank is mechanically associated with the inside diameter of the end cap. 2. The apparatus of claim 1, wherein the eye of the rod end is connected to the movable member.3. The apparatus of claim 1, further comprising a connector affixing the load balancing assembly to the main housing.4. The apparatus of claim 1, wherein the main housing comprises a tail end connected to the structural member.5. The apparatus of claim 1, wherein the structural member comprises a door panel.6. The apparatus of claim 1, wherein the motion transfer assembly comprises:a shaft mechanically associated with the foot of the rod end, with the shaft being enclosed in the main housing; a gear assembly mechanically associated with the shaft; and a motor mechanically associated with the gear assembly. 7. An apparatus for effecting movement between a structural member and a movable member, the apparatus comprising:a main housing having a tail end connected to the structural member; a shaft connected to the main housing; a gear assembly mechanically associated with the shaft and the main housing; a motor mechanically associated with the shaft and the gear assembly; a rod end having an eye, a shank, and a foot; with the eye of the rod end connected to the movable member and with the foot of the rod end mechanically associated with the shaft; a spring housing having a base and a side; a connector affixing the base of the spring housing to the main housing; a spring for receiving a load and distributing the load to the main housing via the base of the spring housing and the connector, the spring having one end and a distal end, with the one end affixed to the base of the spring housing; and an end cap, including a beveled edge, to which the distal end of the spring is affixed, with the end cap surrounding and interacting with the shank of the rod end. 8. The apparatus of claim 7, wherein the connector comprises a threaded joint articulated to the main housing.9. The apparatus of claim 7, wherein the end cap comprises a disk forming an aperture therein.10. The apparatus of claim 9, wherein the disk further comprises an inside diameter having threading mechanically associated with the shank of the rod end.11. An apparatus for effecting movement of an aircraft door panel relative to a movable member, the apparatus comprising:a main housing having a tail end connected to the aircraft door panel; a shaft connected to the main housing; a gear assembly mechanically associated with the shaft and the housing; a motor mechanically associated with the shaft and the gear assembly; a rod end having an eye, a shank, and a foot with the eye of the rod end connected to the movable member and with the foot of the rod end mechanically associated with the shaft; a spring housing having: a side; and a base having a threaded joint articulated to the main housing; a spring for receiving a load and distributing the load to the main housing via the base of the spring housing and the threaded joint, the spring having one end and a distal end, with the one end affixed to the base of the spring housing; and a disk forming an aperture therein, with the disk having an inside diameter with threading mechanically associated with the shank of the rod end, an outside perimeter area to which the distal end of the spring is affixed, and a beveled edge. 12. An aircraft door panel assembly having a load balancing actuator, the load balancing actuator comprising:an aircraft structure; a movable member; a main housing having a tail end connected to the aircraft structure; a rod end having an eye, a shank, and a foot, with the eye of the rod end connected to the movable member; a shaft mechanically associated with the foot of the rod end; a gear assembly mechanically associated with the shaft and the housing; a motor mechanically associated with the shaft and the gear assembly; a spring housing having a side, a base, and a connector, the connector connecting the base of the spring housing to the main housing; a spring for receiving a load and distributing the load to the main housing via the base of the spring housing and the connector, the spring having one end and a distal end, with the one end affixed to the base of the spring housing; and an end cap having an inside diameter and a beveled edge; wherein the end cap is affixed to the distal end of the spring. 13.
