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 hydraulic radial piston engine (1) with a rotary cylinder (5) that rotates about a rotational axis (20), the radial piston engine (1) comprising radially arranged pistons (4) which are actively connected with a cam disk (2), and a housing portion (13) in which a hydraulic distributor (10) is arranged, the housing portion (13) being connected in a positionally fixed manner with the cam disk (2) such that the radial piston engine (1) is connected to a further housing portion (12) to produce a structural unit, wherein, when the radial piston engine (1) is separated from the further housing portion (12), a spring force biases the rotary cylinder (5) in a direction along the rotation axis (20), from a first position to a second position,the rotary cylinder (5), in the second position, either directly or indirectly engages with the cam disk (2) so as to prevent further axial movement of the rotary cylinder (5), and when the rotary cylinder (5) is in the first position, the rotary cylinder (5) counteracts the spring force so that the rotary cylinder (5) moves axially away from engagement with the cam disk (2),the radial piston engine (1), when in the first position, is connected to the further housing portion (12) not supported on the cam disk, andthe cam disk (2) is located adjacent to both the housing portion (13) and the further housing portion (12) and spaces and separates the housing portion (13) from the further housing portion (12). 2. The hydraulic radial piston engine (1) according to claim 1, wherein the rotary cylinder (5) has a groove in which a disk (18) is arranged, and the groove has a diameter such that the disk (18) is brought into at least partial contact against the cam disk (2). 3. The hydraulic radial piston engine (1) according to claim 1, wherein the distributor (10) is supported along the rotational axis (20), against the rotary cylinder (5), by a plurality of springs (21) arranged and located between between the housing portion (13) and the distributor (10). 4. The hydraulic radial piston engine (1) according to claim 1, wherein the rotary cylinder (5) is supported on a bearing (11) which, when the radial piston engine (1) is connected to the further housing portion (12), is supported on the further housing portion (12), and at least an inner ring (15) of the bearing (11) is positionally fixed, at least in the direction along the rotation axis (20), by a drive shaft (6), and the drive shaft (6) is supported, in the direction along the rotation axis (20), either indirectly or directly on the rotary cylinder (5). 5. The hydraulic radial piston engine (1) according to claim 1, wherein the rotary cylinder (5) is supported on a bearing (11) which, when the radial piston engine (1) is connected to the further housing portion (12), is supported on the further housing portion (12), and an inner ring (15) of the bearing (11) is held positionally fixed by a drive shaft (6) against the rotary cylinder (5), at least in the direction along the rotation axis (20), and the drive shaft (6) is supported, in the direction along the rotation axis (20), either indirectly or directly on the housing portion (13) with which the hydraulic distributor (10) is associated. 6. The hydraulic radial piston engine (1) according to claim 5, wherein the housing portion (13) has an opening positioned coaxially with the rotation axis (20) on which a bolt (23), connected to the driveshaft (6), is supported whereby the driveshaft (6), the bearing (11) and the rotary cylinder (5) are held in the housing portion (13). 7. The hydraulic radial piston engine (1) according to claim 6, wherein the bolt (23) is removable when the radial piston engine (1) is connected to the further housing portion (12). 8.
