The invention discloses a ship shafting segmented stern tube device and an installation method thereof. The ship shafting segmented stern tube device includes a stern tube, and the stern tube is divided into a front stern tube and a rear stern tube; The front ends of the front and rear tail pipes are connected to the front and middle bearing housings through the first and second loose sleeve joints, and the rear ends of the front and rear tail pipes are connected to the middle and rear bearings through the first and second epoxy gland flanges. seat connection. The installation method is to install the oil pipe and cable pipe in the tail pipe first, and then install the rear ends of the front and rear tail pipes on the middle and rear bearing seats through the first and second epoxy gland flanges, and the front and rear tail pipes The front end of the pipe is first supported by a tooling frame; the tail shaft and the head and tail seals are hoisted. After the tail shaft is hoisted into place, the tooling frame is removed, and the first and second loose sleeve joints are installed. In the present invention, the tail pipe is set as a segmented tail pipe, and then the tail pipes of each section are connected by loose sleeve joints, epoxy gland flanges and axial and end face seals, which greatly improves the efficiency of installation and cleaning.
Description
technical field [0001] The invention relates to the field of ship equipment, in particular to a ship shafting segmented stern tube device and an installation method thereof. Background technique [0002] There are mainly two types of traditional ship shafting stern tubes. The short stern tubes are prefabricated in the field or the segmented stern tubes are welded and joined in the field. These two types of traditional ship shafting stern tubes are finally welded into a monolith. Usually, the short shaft system is an integral type that is prefabricated by the short tailpipe in the inner field, while the long shaft system is connected as an integral type by on-site welding and splicing in the field of the segmental tailpipe, that is, the bearing body is installed on the shaft hub, The two ends of the pipe of the tail pipe are respectively welded on the axle hub. It is difficult to install and position the integral stern tube on the berth of the outfield, and it requires high...
