Problems solved by technology

[0002] At present, there are several types of water-lubricated composite rubber bearings, each with its own characteristics. With the development of production technology, the performance of water-lubricated composite rubber bearings needs to be continuously improved. Water-lubricated composite rubber bearings, water-lubricated composite rubber bearings combined with linear arc grooves and arc surfaces, water-lubricated composite rubber bearings combined with linear right-angle grooves and arc surfaces, and spiral arc grooves combined with regular polygonal planes More excellent bearings such as water-lubricated composite rubber bearings, but the existing water-lubricated composite rubber bearings have a small load-carrying capacity, high friction and wear, low ability to discharge sediment and impurities, and short service life

Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] The spiral groove water lubricated rubber alloy bearing involved in the present invention, such as figure 2 Shown consists of a metal or non-metal shell 1 and a special rubber alloy inner bushing 2. Such as figure 1 As shown in the lubricating structure of the special rubber alloy inner bush 2, the spiral arc grooves 3 are designed to be evenly distributed in the circumferential direction and spirally distributed in the axial direction. The number of spiral arc grooves 3 can be multiple, and the spiral arc grooves The arc radius of groove 3 is R 4 , the working surface of the adjacent spiral arc groove 3 is composed of the arc surface 6, the arc surface 5 and the arc surface 4, and the working surface is evenly distributed in the circumferential direction.

[0014] The working principle of the spiral groove water-lubricated rubber alloy bearing inn...

Abstract

A spiral water lubricated rubber-metal bearing comprises a rubber-metal lining and a metallic or nonmetallic housing. The lubrication structure of the special rubber-metal lining uses spiral circular grooves being uniform distribution along circumference and axial spiral distribution, and the working surface of the neighbouring grooves consists of a plurality of circular curves. The structure of the invention can form elastohydrodynamic lubrication easily, and water film support is formed between the drive shaft and the bearing, so as to reduce the friction loss.

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, there are several types of water-lubricated composite rubber bearings, each with its own characteristics.
