A kind of outer ring slotted joint bearing

technical field

The utility model relates to the technical field of aircraft structure design, in particular to an outer ring slotted joint bearing.

Background technique

As we all know, bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial size, vibration and noise are larger, and the price is also higher. Sliding bearings are bearings that work under sliding friction. The sliding bearing works smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, which can also greatly reduce friction loss and surface wear, and the oil film also has a certain ability to absorb vibration. But starting frictional resistance is bigger. The part of the shaft supported by the bearing is called the journal, and the part that matches the journal is called the bearing bush. In order to improve the frictional properties of the bearing pad surface, the layer of anti-friction material cast on its inner surface is called bearing bushing. The materials of bearing bushes and bearing linings are collectively referred to as sliding bearing materials. Sliding bearing applications are generally under low-speed and heavy-load conditions. In China, repair welding, inlaid shaft sleeves, pitting and other methods are generally used for sliding bearing wear in China. However, when the material of the shaft is No. 45 steel (quenched and tempered), if only surfacing treatment is used, welding internal Under heavy load or high-speed operation, cracks or even fractures may appear at the shaft shoulder. If stress relief annealing is used, it is difficult to operate, and the processing cycle is long and the maintenance cost is high; when the material of the shaft is HT200 , the use of cast iron welding is not ideal. Some enterprises with high maintenance technology will use brush plating, laser welding, micro-arc welding and even cold welding, etc. These maintenance technologies often require high requirements and high costs. The spherical plain bearing is a sliding bearing. In the prior art, the spherical plain bearing mostly adopts an extruded structure, and the process is simple, but the outer ring of the bearing is soft, has low load-carrying capacity, is easy to wear, and is not easy to replace.

The technical problem that needs to be solved urgently now is how to design a bearing that can overcome the adverse effects of the above-mentioned prior art in the production and use of sliding bearings.
