The invention provides an auxiliary braking device and method for a ship propulsion shafting. The auxiliary braking device for the ship propulsion shafting comprises a transmission shaft rotationally installed on a shaft seat and a first support fixedly installed at the bottom of the shaft seat; a brake disc arranged on the transmission shaft in a sleeving manner; and four positioning mechanisms which are arranged on the two sides of the transmission shaft respectively, are located on the two sides of the brake disc respectively, and are distributed in a pairwise corresponding mode, wherein each positioning mechanism comprises a positioning cover, a reset groove, a sliding piece, a bolt, two positioning grooves, two positioning rods and two contact pieces, and the positioning cover is fixedly installed on one side of the transmission shaft. The auxiliary braking device and method for the ship propulsion shafting have the advantages that the brake disc is convenient to install, the replacement mode is simple, the installation is stable, an auxiliary braking brake pad can be cooled, and the failure rate is reduced.

    本发明提供一种船舶推进轴系辅助制动装置及方法。所述船舶推进轴系辅助制动装置及方法包括转动安装在轴座上的传动轴和固定安装在轴座底部的第一支座;刹车盘,所述刹车盘套设在所述传动轴上;四个定位机构,四个所述定位机构分别设置在所述传动轴的两侧,四个所述定位机构分别位于所述刹车盘的两侧,四个所述定位机构两两对应分布,所述定位机构包括定位罩、复位槽、滑片、螺栓、两个定位槽、两个定位杆和两个接触片,所述定位罩固定安装在所述传动轴的一侧。本发明提供的船舶推进轴系辅助制动装置及方法具有便于安装刹车盘、更换方式较为简单、安装较为稳定、且能够对辅助制动刹车片降温、降低故障率的优点。
