Rubber bearing for low-speed heavy-load environment

Abstract

The object of the present invention is to provide a rubber bearing for low-speed and heavy-duty environments, including a bearing housing, a control valve, and a pump. The inner wall of the bearing housing is provided with slats, and the slats are fixed to the bearing housing by bolts. Axial flow holes are set in the axial direction, radial flow holes are set in the radial direction of the bearing shell, tangential flow holes are set in the position tangent to the inner wall of the bearing shell inside the bearing shell, and a main pipe is set on the outer wall of the bearing shell. The control valve and the pump are connected in sequence through the pipeline. The radial flow hole, tangential flow hole and axial flow hole are all connected. The end of the axial flow hole is connected to the main pipe. Corresponding to the position of the water hole. The invention directly injects water with a certain pressure into the gap between the shaft and the bearing through the water hole to form an effective dynamic pressure lubrication method; the opening position of the water hole can be arranged in a targeted manner according to the actual load state of different ship bearings, So as to achieve better results.

Description

technical field [0001] The invention relates to a friction member, specifically a bearing. Background technique [0002] Due to the advantages of water-lubricated rubber bearings such as pollution-free and corrosion-resistant, they have been widely used in various types of river and sea ships. For civil ship shafting, controlling operating costs and increasing bearing service life are the primary conditions for selecting bearings, so reduce Friction and wear of a bearing system is an important indicator that is prioritized in bearing design. Under the rated operating conditions of the shaft system, the shaft and the bearing are separated by a layer of water film. Due to the shearing effect of the water film, the friction coefficient is not large, and the shaft and bearing running in the hydrodynamic lubrication stage have very little wear. Almost negligible. However, during the low-speed navigation stage of the ship, especially the start-up stage of the ship shafting, the ...

Problems solved by technology

However, as a lubricating medium for rubber bearings, the viscosity of water is very low. For shafting start-up and low-speed operation conditions, it is still difficult to establish a water film based on self-lubricating conditions. For objects with heavy bearing loads such as ship stern bearings, This is particularly the case
