In actual use, since the shaft system is a rotating part, and the mating surface of the spacer ring is a smooth plane, there will be a small gap on the mating surface after installation. During the rotation of the shaft, the hydraulic oil in the shaft is under centrifugal force. Under the action of the shaft, it leaks from the inside of the shaft along the gap of the butt joint surface to the surface of the shafting, and is thrown into the engine room. On the one hand, it affects the safe and reliable use of the shafting, and on the other hand, it also pollutes the working environment of the engine room. Requires constant replenishment of hydraulic oil

The invention provides a Z-shaped sealing and separable type distance ring device for a ship. The device comprises a distance ring, pins, first screws and second screws, wherein the distance ring comprises a first section and a second section in a splitting type; partial regions of the butting joint face of the first section and the second section are arranged to be Z-shaped butting joint faces respectively and correspondingly; pin holes and first screw holes are formed in axial side walls of the first section and the second section respectively and correspondingly; second screw holes are formed in the first section, the second section and shaft sections which are connected with the first section and the second section respectively and correspondingly; the pins are fit with the pin holes formed in the axial side walls of the first section and the second section; the first screws are fit with the first screw holes formed in the axial side walls of the first section and the second section; and the second screws are fit with the second screw holes formed in the first section, the second section and shaft sections which are connected with the first section and the second section. According to the device, the separable type distance ring has excellent sealing property, and the problem of oil leakage is avoided; and the device is convenient to install and disassemble.
Description
[0001] technical field [0002] The invention relates to a Z-shaped seal separable spacer ring device for ships. [0003] Background technique [0004] In the process of shafting design and installation, the actual length of the shaft section will deviate from the design length, and the installation of the separable distance ring can effectively compensate for the deviation, and it is convenient for processing and grinding, which can avoid the deviation of the shaft segment processing. [0005] The existing separable distance ring is divided into two parts, and its butt joint surface is a smooth plane, and is fastened by screws and pins. In actual use, since the shaft system is a rotating part, and the mating surface of the spacer ring is a smooth plane, there will be a small gap on the mating surface after installation. During the rotation of the shaft, the hydraulic oil in the shaft is under centrifugal force Under the action of the shaft, it leaks from the inside of th...
