Problems solved by technology

[0013] The thermal stress of brazing cannot be effectively eliminated, resulting in easy welding after brazing
The reason is: the tile surface material is polytetrafluoroethylene plastic, and its thermal expansion coefficient is much larger than that of the tile base. Brazing is carried out in a heated state. After brazing, it is cooled, and the temperature difference will cause residual tensile stress in the plastic layer of the tile surface. When the bonding strength of the brazing layer is exceeded, it will cause open welding

Embodiment Construction

[0033] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0034] Such as Figures 1 to 3 As shown, the sliding bearing of the embodiment of the present invention includes a shoe base 10, a composite shoe surface 30 disposed on the shoe base 10, and a brazing layer arranged between the shoe base 10 and the composite shoe surface 30. The inner periphery of the shoe base 10 A solder containing groove 11 is opened on the surface, and there is a solder block integrally formed with the brazing layer in the solder containing groove 11 .

[0035] During the soldering process, a certain amount of solder can be stored in the solder holding tank 11 . The solder holding grooves 11 provided at both ends of the semicircular tile base 10 can replenish the solder l...

Abstract

The invention provides a sliding bearing and a manufacturing method thereof. The sliding bearing includes a tile base, a composite tile surface arranged on the tile base, and a brazing layer arranged between the tile base and the composite tile surface. A solder containing groove is opened on the tile base, and a brazing layer is integrated in the solder containing groove. formed solder bumps. Applying the technical solution of the present invention, the brazing layer between the composite tile surface and the tile base is integrated with the solder block in the solder holding tank, which increases the bonding strength between the brazing layer and the tile base and effectively reduces the brazing layer. The probability of open welding between the solder layer and the tile base.

Description

technical field [0001] The present invention relates to the field of radial bearings, more specifically, to sliding bearings and a manufacturing method thereof. Background technique [0002] The composite tile surface is a low-friction, high-wear-resistant composite material formed by metal wire elastic pads and reinforced modified PTFE through molding, sintering and plasticization, and then firmly combined with tile bases of different geometric shapes through brazing technology. Formed plastic tile products. At present, the products have been widely used in thrust bearings of vertical and horizontal hydroelectric generator sets and planetary gear train gearboxes. Its characteristics are as follows: [0003] 1. It is suitable for different support methods and different lubricating oil circulation cooling methods; [0004] 2. The friction coefficient is small, effectively reducing the running loss of the bearing bush; [0005] 3. It has excellent anti-occlusion performanc...
