Problems solved by technology

However, the technical characteristics of the "waterproof ring" will lead to increased wear of the bearing and shaft during normal work, high heat generation, and large frictional power consumption. Due to the wear of the seal when the seal is not usually needed, the seal will fail, and water will enter the engine room. Then the seal can't work, which affects the working life of both

Abstract

The invention relates to the technical field of bearing devices for ships, in particular to an emergency waterproof device for a bearing for a ship. The emergency waterproof device comprises a shell, an inflation start device, an inflation device and a pneumatic tire. The inflation start device comprises a trigger element and an inflation device start rod. The shell comprises a gas inlet chamber and a water inlet chamber which are spaced. The trigger element, the inflation device start rod and the inflation device are sequentially and vertically distributed and installed from bottom to top. The trigger element is located in the water inlet chamber and is a float-type trigger element or a water-sensitive component type trigger element. Meanwhile, the invention further provides a waterproof sealing bearing provided with the waterproof device for the bearing. By means of the emergency waterproof device for the bearing for the ship, a sealed part needing waterproofness is not heated or abraded during work of the bearing when there is no water in a cabin. A rotary shaft and the bearing can continue to work for a few days after water enters an engine room. The emergency waterproof device is convenient to manufacture, easy to install, quick in trigger response, easy to manage and use and good in robustness.

Description

technical field [0001] The invention relates to the technical field of marine bearing devices, in particular to an emergency waterproof device for marine bearings and a bearing containing the device. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial size, vibration and noise are larger, the carrying capacity is not large enough, and the price is higher. Sliding bearings generally include bearing housings, bearing caps, oil injection holes and studs. The bearing housings are connected to the machine base, and the ...
