Bushing for leaf spring Bimetal bearing bush Clutch Bimetallic bushing 

 

Introduction:

 

      1.  Bimetal bearing bush has a combination of high strength, load-bearing capacity, and the advantages of good wear resistance. Particularly suited to medium-speed and low-speed high-contained set and so on.


      2. Process through special means, at the friction surface can be processed into a variety of oil and oil hole and the hole in order to adapt to different working conditions lubrication use.

 

      3. Products widely used in automotive engine, chassis, motorcycle clutch, gear pump rub board and lifting equipment and other fields.

Q:What are the properties of plain bearing alloys?
1, enough strength and hardness;2, high wear resistance and small friction coefficient;3, enough plasticity and toughness, higher fatigue strength;4, good heat resistance grade corrosion resistance;5, good running in.
Q:What are the major damage forms of plain bearings?
Two: sliding bearings (sliding, bearing), work under sliding friction bearings. Plain bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by the lubricant without direct contact, and the friction loss and surface wear can be greatly reduced. The oil film also has a certain vibration absorption capacity. But the starting friction resistance is larger. The shaft supported by the bearing is called the journal, and the part that matches the journal is called the bush. In order to improve the friction properties of the bearing surface, the antifriction material layer, which is cast on its inner surface, is called the bearing lining. Bearing and bearing lining materials are collectively referred to as journal bearing materials. The application of sliding bearings is generally under low speed and heavy load conditions.
Q:Who says that the sliding bearing motor is better than the ball bearing motor?
The rolling ball bearing is the ball, roller bearings should be cylindrical roller bearing, rolling body inside the cylinder, a bearing point contact, less friction, high working speed limit, but the bearing capacity is small, suitable for high speed and light load.
Q:Where are the upper plain bearings?
Plain bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by the lubricant without direct contact, and the friction loss and surface wear can be greatly reduced.
Q:What are the ways to flush bearings?
The test, can be used to clean the remaining oil scraping feeler, apply the thumb, index finger back and forth slowly rubbing fingers if there is research, the rustling sound, it indicates that the bearing is not clean, should wash again. The bearing in hand, pinch the inner ring, the outer ring (toggle horizontal rotating large bearings can be placed in the assembly stage, the inner pad, the outer ring is suspended, pressing within the circle, rotating outer ring), with flexible rotation, no block, no beating for qualified. After cleaning the bearings, fill in the lubricant, it should be placed on the assembly table, the next pad with a net cloth or paper pad, covered with plastic cloth, pending assembly, not allowed on the ground or box. When moving bearings, it is not allowed to use the hand directly, Dafanb gloves or net cloth should be used to pack the bearings before they are taken. Otherwise, because of the sweat and moisture in the hands, it is easy to cause the bearings to be rusted. On both sides of the bearing with shields or seals, and bearings coated with anti rust, lubrication and oil, because at the time of manufacture have been injected into the grease, so do not wash before installation, for example, 51708ZHS - 12, and - 12 type tractor and redguards Dongfanghong 20 tractor clutch (original code 688808) bearing.
Q:What is the difference between rolling bearings and plain bearings?
Sliding bearing applications are generally under low speed heavy load conditions, or maintenance and lubrication of the difficult parts of the operation. Radial bearings in rolling bearings (mainly bearing radial forces) are usually composed of 4 parts: inner ring, outer ring, rolling body and rolling body cage. The inner ring is tightly sheathed on the shaft neck and rotates with the shaft, and the outer ring is arranged in the bore of the bearing seat. In the inner and outer peripheral inner raceway are made. When the inner and outer rings rotate relative to each other, the rolling bodies roll on the raceway of the inner and outer rings, and they are separated by the cage to avoid mutual friction. The thrust bearing is divided into two parts: the tight ring and the movable ring. The tight ring is tight with the shaft sleeve and the movable ring is supported on the bearing seat. Rings and rolling bodies are usually made of rolling bearings steel with high strength and good wear resistance, and the surface hardness should reach HRC60 - 65 after quenching. The holder with mild steel punch made of copper alloy can also be used bakelite cloth or plastic manufacturing.
Q:What are the differences between rolling bearings and plain bearings? What are their respective applications?
So, in heavy load situations and requirements of the radial dimensions small, compact structure requirements of occasions (such as the crankshaft bearings, rolling mill, roller bearing) with sliding bearing; rolling bearing vibration and noise, so on The precision requirement is very high, and no vibration occasions, rolling bearings generally difficult to do, is a rolling bearing rolling body adopts the sliding bearing.x0d the main difference often (ball, roller, tapered roller, needle roller bearing), there is no difference between the rolling body.x0d rolling bearing and sliding bearing the first appearance of the structure on the rolling bearing is a rotating body by rolling to support the rotating shaft, which is a point of contact area, rolling body more, nine more points of contact; x0d sliding bearing is on the smooth surface to support the rotating shaft, which is a surface contact area.
Q:Can I use plain bearing in high temperature environment?
The vacuum environment, is expected to 200 degrees temperature, want to use the sliding bearing, mainly on account of the small space, the environment is not suitable for sliding bearing, sliding bearing can be at a temperature of about 200 degrees, but the high temperature expansion, easy to get stuck.
Q:How does a sliding bearing move at work?
Plain bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by the lubricant without direct contact, and the friction loss and surface wear can be greatly reduced. The oil film also has a certain vibration absorption capacity. But the starting friction resistance is larger. The shaft supported by the bearing is called the journal, and the part that matches the journal is called the bush.
Q:How is the sliding bearing (bushing) axially fixed? Ten
The sliding bearing (bushing) is axially fixed: 1. through interference fit. 2. step type sliding bearing fixing.
