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.

A disengage mechanism for a gear drive including rotatable drive and driven members with one of the members having first splines. A drive actuator having second splines and being connected to rotate with one of the members and axially movable with respect thereto between first and second positions. In the first position the first and second splines are engaged and the drive and driven members are connected to rotate together and in the second position the splines are disengaged and the drive and driven members are disconnected. First means are provided for moving the drive actuator to the first position and second means move the actuator to the second position. The first means include a spring which constantly urges the drive actuator to the first position and the second means comprises a rotatable cam member which positively engages the drive actuator to move it to the second position. Means are provided for locking the cam member to the housing of the disengage mechanism and indicia are provided so that an operator of the device will know whether the cam member is either in its first position or its second position. Additionally, the cam member is provided with a detent within which a cam follower resides in the first position of the cam member which prevents accidental movement of the drive actuator from its first position.

A gear drive and disengage mechanism including in combination a housing, a drive motor secured to said housing and having a drive shaft extending into said housing, a sun gear secured to said drive shaft, a planet carrier, a gear shaft carried by said planet carrier, first and second planet gears rotatively carried by said gear shaft with said first planet gear being in meshing engagement with said sun gear, said first and second planet gears being secured together, said housing including a stationary hub, a cover, a first ring gear interposed between said hub and cover and secured thereto, said first planet gear being in meshing engagement with said first ring gear, a second rotatable ring gear having a drive portion with first axial splines, said second planet gear being in meshing engagement with said second ring gear, an output spindle rotatably mounted on bearings carried by said stationary hub and positioned coaxial with said second rotatable ring gear, wall means defining a bore extending axially into said output spindle, a drive actuator located within said bore in said output spindle and having means connecting said drive actuator to said spindle and permitting axial movement of said drive actuator between first and second positions relative to said spindle, said drive actuator having second axial splines thereon engageable with said first axial splines in said first position of said drive actuator to connect said drive portion of said second ring gear to said spindle, said drive actuator in said second position disconnecting said spindle from said drive portion of said second ring gear, a cam member surrounding one portion of said drive actuator and having a cam surface thereon, a pin carried by said drive actuator and engageable with said cam surface, a spring engaging said drive actuator to at all times urge said drive actuator to its said first position, said cam member being rotatable between first and second positions and in moving to said first position removing camming force from said pin and permitting said spring to move said drive actuator to its said first position, said cam member in moving to its said second position causing said cam surface to engage said pin with a camming force to positively move said drive actuator to its said second position against the urging of said spring, a cam actuator surrounding at least a portion of said cam member and extending exteriorly of said bore in a position to be manipulated by an operator of the gear drive and disengage mechanisms, a drive pin extending through said cam actuator and said cam member to connect the two together whereby rotation of said cam actuator causes rotation of said cam member between its said first and second positions, a retainer plate secured to said output spindle to close said bore and having an opening through which said cam actuator extends, a lock member carried by said retainer plate and movable between locked and unlocked positions, spring means constantly urging said lock member to locked position, wall means on the periphery of said cam actuator defining first and second angularly spaced detents with said lock member residing in said first detent in said first position of said cam member and residing in said second detent in said second position of said cam member, indicia on said retainer plate and said cam actuator to visually indicate the position of said cam actuator and said cam member, said cam surface of said cam member having a detent portion to receive said pin carried by said drive actuatoR in said first position of said cam member which insures against axial movement of said drive actuator from its said first position until initial rotation of said cam member to remove said pin from said detent portion of said cam surface.
