Problems solved by technology

[0002] For a long time, the key components such as bearings and sealing devices in the mechanical transmission system are generally composed of metal components and mineral oil is used as the lubricating medium. On the one hand, there are inevitably relatively large friction, wear, vibration, noise, and non-functional Consumption, seal leakage, environmental pollution, etc., waste a lot of strategic resources such as mineral oil and precious metal materials, especially the shafting structure of the ship stern shaft propulsion system is complicated, the shaft alignment is difficult to debug, and the leakage of lubricating oil pollutes water resources and the environment The increasingly serious status quo and the major problems of vibration and noise reduction in weapons and equipment; on the other hand, it also causes problems such as poor overall performance and reliability of mechanical transmission systems, and shortened service life of equipment.

Embodiment 1

[0029] The water-lubricated mechanical transmission system uses a closed water-lubricated transmission device for the working process of the ship's stern shaft propulsion system:

[0030] As shown in Figure 1, the high elastic coupling connects the driving shaft 3 and the driven shaft 12 respectively, and the sealing device, the front water lubricated bearing and the front bearing seat 1, and the water lubricated dynamic seal are installed in sequence on the driven shaft 12. Bearing and rear bearing housing 2. Water is first injected into the water tank 45 through the water supply channel, and the low water level switch 48 can control the height of the water level in the water tank. Turn on the water flow switch 52, the pump 49 enters the water in the water tank into the sealing device through the water inlet screw head 32, the airbag seal 20 is not inflated, and the water can enter the front water lubricated bearing and the water lubricated dynamic sealed bearing for lubricat...

Embodiment 2

[0036] The water-lubricated mechanical transmission system adopts the open water-lubricated transmission device and is applied to the working process of the ship stern shaft propulsion system:

[0037] As shown in Figure 2, the high-elastic coupling connects the driving shaft 3 and the driven shaft 12 respectively, and the sealing device, the front water lubricated bearing and the front bearing seat 1, the flange type water lubricating Lubricate bearings and rear bearing housing 2. Turn on the water flow switch, the pump 49 will directly enter the seawater outside the hull into the sealing device through the filter device 53, the flow meter 51 and the water inlet coil head 32, the airbag seal 20 is not inflated, and the water can enter the front water lubricating bearing and the method. Lubricated in blue-type water-lubricated bearings.

[0038] When the propulsion shaft rotates in the front water-lubricated bearing and the flange-type water-lubricated bearing, on the one han...

Abstract

The high performance water lubricated mechanical driving system based on new type of composite engineering material includes a high elasticity shaft coupler, a sealing device, a front water lubricated bearing, a back water lubricated bearing, and a water supplying system. It his natural water as lubricating medium and has or has not dynamic sealing device mounted through the back water lubricated bearing to constitute a closed or opened water lubricated mechanical driving system. Compared with traditional mechanical driving system, the high performance water lubricated mechanical driving system has greatly lowered friction, wear, vibration, noise and no-work loss, greatly raised reliability, saving in mineral oil and noble metal material, and environment friendship, and may be applied widely.
