Embodiment 1

[0022] A water-lubricated dynamic-seal rubber alloy bearing for ship propulsion system

[0023] Such as image 3 As shown, the water-lubricated dynamic-sealed rubber alloy bearing is installed in the bearing seat 16, and is fixed on the bearing seat 16 by four screws 18 evenly distributed on the end surface. Two static sealing rings 9 and 10 are used to prevent the entry of water and the leakage of oil in the gap between the outer surface of the water-lubricated dynamic seal rubber alloy bearing and the inner surface of the bearing seat 16. Four water injection holes 17 are evenly distributed on the circumference of the bearing seat, and these four water injection holes 17 correspond to the four water injection holes 11 of the water-lubricated dynamic sealing rubber alloy bearing, and the axis lines thereof coincide with each other. The left side of the bearing seat 16 is the power plant of the ship's propulsion system, and the right side of the bearing seat 16 is the power o...

[0027] A water-lubricated, dynamic-sealed rubber alloy bearing used in the stirring drive system of a washing machine

[0028] Drive the drive shaft of the agitator in the washing machine to realize the washing function, pass through the water-lubricated dynamic-sealed rubber alloy bearing and connect with the power system. When the washing machine is in working condition, the water in the washing machine will flow into the water-lubricated dynamic seal rubber alloy bearing along the transmission shaft. At this time, the dynamic seal body of the water-lubricated dynamic seal rubber alloy bearing can prevent water from entering the washing machine through the dynamic seal body The power system of the water-lubricated dynamic-seal rubber alloy bearing is connected to the drainage system of the washing machine simultaneously, so the water flowing into the water-lubricated dynamic-seal rubber alloy bearing can flow out through the water injection hole 11.

Abstract

The present invention relates to a water lubrication slip-sealing rubber alloy bearing. It is formed from external shell made of metal or non-metal material and interior structure formed from special rubber alloy internal liner bushing and slip-sealing body which are combined into one body. Said invention also provides the concrete interior structure of said liner bushing and said shell body.

Description

technical field [0001] The invention belongs to a mechanical transmission device in mechanical engineering, in particular to a water-lubricated bearing device. technical background [0002] At present, various ship propulsion systems and other industrial equipment sailing in the Three Gorges reservoir area and rivers, lakes and seas generally use metal bearings and use oil as the lubricating medium, and the shaft seals inevitably have lubricating oil leakage, which seriously pollutes the water environment. At the same time, it consumes a lot of lubricating oil and precious metals; on the other hand, in order to prevent the leakage of lubricating oil or the entry of water outside the equipment, the shafting structure adopted is quite complicated and has poor reliability, and it is difficult to reduce or reduce the shafting Problems such as friction, wear, vibration, impact, noise, reactive power consumption, short life, complicated assembly and disassembly and maintenance, an...
