Abstract

The invention provides a water retaining shaft sleeve and pod propelling open-water test equipment, and relates to the technical field of pod performance testing. The water retaining shaft sleeve comprises a shaft sleeve body. The shaft sleeve body comprises a first side portion and a second side portion. A first arc groove is formed in the first side portion, a second arc groove is formed in thesecond side portion, and a shaft hole with which a vertical transmission shaft is sleeved can be defined by the first arc groove and the second arc groove. According to the water retaining shaft sleeve, the connection manner of penetration sleeving of an original water retaining shaft sleeve is changed, a detachable side plate opening manner is adopted, the first side portion and the vertical transmission shaft can be adaptively mounted firstly, the gap between an instrument and the first arc groove can be conveniently observed when the internal instrument is mounted, interference is preventedfrom being generated, thus, a shaft sleeve inner hole can be made smaller, and the measuring precision is improved.

Description

technical field [0001] The invention relates to the technical field of pod performance testing, in particular to a water retaining bushing and pod propulsion open water test equipment. Background technique [0002] With the development of pod propulsion technology, more and more ships have begun to use pod propulsion instead of traditional propulsion methods to obtain better speed, maneuverability, vibration performance and more flexible cabin layout. In order to obtain the rapid performance of this type of ship in the design stage, it is still necessary to use the tank model test to obtain relevant data; and the open water test is an essential part of it. Different from the conventional propulsion method, which requires only a single propeller in the open water test, the open water test of the pod propulsion ship model requires an additional open water test with a pod package, which requires not only the right-angle transmission, but also the entire pod propulsion system. ...
