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 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

A spindle for a winch which comprises a first member for winding a length of a restrain and a second member for rotationally driving the first member. The second member engages with the first member by way of an arrangement which only permits relative rotational movement between the first and second members in one direction. A portion of the second member is received into a bore in the first member to support the second member with respect to the first member.

1. A spindle for a winch including: a first member for winding a length of a restraint;a second member for rotationally driving the first member;the second member engages with the first member by way of an arrangement which permits relative rotational movement between the first and second members in only one direction;a portion of the second member being received into a bore in the first member to support the second member with respect to the first member;the second member includes radially outwardly projecting portions, anda cap plate surrounding the second member and securing the second member to the first member by trapping the projecting portions. 2. The spindle according to claim 1, wherein the portion of the second member has a sliding fit in the bore of the first member. 3. The spindle according to claim 1, wherein the second member engages with the first member by way of a ratchet arrangement which includes at least one cam and a plurality of followers which form the projecting portions. 4. The spindle according to claim 3, wherein the plurality of followers are oriented to move radially with respect to an axis of rotation of the spindle. 5. The spindle according to claim 3, wherein the plurality of followers are mounted on leaf springs. 6. The spindle according to claim 3, wherein the plurality of followers engage the cam in a compressive mode. 7. The spindle according to claim 3, wherein and the at least one cam and the cam followers are located between fasteners for the cap plate and the rotational axis of the first member. 8. A spindle comprising: a first member for winding a length of a restraint, and a first end of the first member supporting a plurality of teeth;a leading end of a second member being received within a bore formed within the second end of the first member for rotatably supporting the second member with respect to the first member and permitting relative rotational rotation between the first and the second members so that the second member facilitates rotationally driving the first member in only one rotational direction,the second member supporting a plurality of cam followers which are spring biased radially outward away from a rotational axis of the first member,at least one ring member supporting a radially inward facing cam surface for releasable engaging with the plurality of cam followers, anda cap plate at least partially surrounding the second member and coupling the at least one ring member and the second member to the first member, and the cap plate being secured to the first member by fasteners which are spaced radially from the rotational axis of the first member. 9. The spindle according to claim 8, wherein the end of the second member which is received within the bore formed within the second end of the first member has a sliding fit. 10. The winch according to claim 8, wherein the plurality of cam followers are each baised radially outward radially away from the rotational axis of the first member by a respective leaf spring. 11. The winch according to claim 8, wherein the cam and cam followers are located between the fasteners for the cap plate and the rotational axis of the first member. 12. A winch comprising a spindle supported by a frame, the spindle comprising: a first member for winding a length of a restraint, and a first end of the first member supporting a plurality of teeth;the frame supporting a releasable pawl arranged for releasably engaging with the teeth of the first member, and the first member being rotatably supported by the frame,a leading end of a second member being received within a bore formed within the second end of the first member for rotatably supporting the second member with respect to the first member and permitting relative rotational rotation between the first and the second members so that the second member facilitates rotationally driving the first member in only one rotational direction,the second member supporting a plurality of cam followers which are spring biased radially outward away from a rotational axis of the first member,at least one ring member supporting a radially inward facing cam surface for releasable engaging with the plurality of cam followers, anda cap plate at least partially surrounding the second member and fixedly coupling the at least one ring member to the first member and rotatably coupling the second member to the first member, the cap plate being secured to the first member by a plurality of fasteners which are spaced radially from the rotational axis of the first member, and the cam and cam followers are located between the plurality of fasteners and the rotational axis of the first member. 13. The winch according to claim 12, wherein the end of the second member which is received within the bore formed within the second end of the first member has a sliding fit. 14. The winch according to claim 12, wherein the plurality of cam followers are each baised radially outward by a respective leaf spring.
