Problems solved by technology
Due to its poor wear resistance and large friction coefficient, the bearing pad runs at a high temperature, and burnout accidents often occur. Moreover, because the bus alloy bearing pad is rigidly supported, it cannot effectively reduce the vibration generated during the operation of the unit. The installation requirements of the unit Higher; the second is the rubber bearing
The natural rubber water-lubricated bearing pads traditionally used have disadvantages such as poor wear resistance, aging resistance, short life, heavy wear on the journal, poor bearing capacity, and high water expansion rate; the third is copper bearing pads.
Poor wear resistance, large friction coefficient, short service life, etc.

Embodiment Construction
[0011] A cylindrical elastic metal-plastic bearing bush, which is welded with four elastic metal-plastic tile surfaces 2 inside a cylindrical metal base 1. The material of the cylindrical metal base 1 is steel or copper, and each elastic metal-plastic tile surface 2 is Lubricating water tank 3 is arranged between, and the width of lubricating water tank 3 is 3-10mm.
[0012] A method for preparing a cylindrical elastic metal-plastic bearing bush, the steps of which are: 1. Elastic metal-plastic tile surface 2. Production: Tin bronze wire with a diameter of 0.4 mm is wound on a 28-inch bicycle frame to form a tight spring, and then Stretch it so that the distance between the springs is roughly equal to the diameter of the springs; cut the stretched long springs into 60mm long springs, sprinkle them in the mold while cutting them, and lightly compact them until the short springs do not fall apart. , take it out and wrap it up for later use. Put a batch of elastic pad blanks pre...

Abstract
The invention relates to a barrel-type elastic metal plastic bearing bush and a preparation method thereof. Two to sixteen elastic metal plastic bush surfaces are welded in a barrel-type metal base body; a lubricating water groove is arranged in each elastic metal plastic bush surface; and the preparation method is realized by the working procedures such as manufacture of the elastic metal plastic bush surface, preparation of welding flux, pretreatment of the elastic metal plastic bush surfaces, brazing and the like. The barrel-type elastic metal plastic bearing bush and the preparation method thereof have the characteristics that the structure is simple, the cost is low, the elasticity is good, the vibration absorbing capability is strong, the friction coefficient is low, the bearing capability is high, the self-lubricating performance and the self-adjusting performance are good, the service life is long, the nonconductivity is realized, the insulation is good, no damage is generated to the shaft in abnormal use, the maintenance is simple and convenient, and the like.
Description
technical field [0001] The invention belongs to the technical field of mechanical transmission, and specifically relates to a cylindrical elastic metal-plastic bearing bush and a production method thereof. Background technique [0002] At present, there are roughly three types of integral cylindrical bearing materials widely used in building materials machinery, papermaking machinery, mineral processing machinery, power generation machinery, ship machinery, iron and steel machinery, compression machinery, petroleum machinery, chemical machinery, coal mining machinery and other machinery: one is Babbitt bearings are used. Due to its poor wear resistance and large friction coefficient, the bearing pad runs at a high temperature, and burnout accidents often occur. Moreover, because the bus alloy bearing pad is rigidly supported, it cannot effectively reduce the vibration generated during the operation of the unit. The installation requirements of the unit Higher; the second is...
