Q: What are the structural types of radial and thrust dynamic journal bearings?: There are many kinds of sliding bearings, which can be divided into two kinds of radial (Xiang Xin) sliding bearing and thrust (axial) sliding bearing according to the direction of bearing load.Sliding bearings can be divided into integral and partial and integral type sliding bearings with bolts connected with the frame. The bearing seat hole pressure, the bearing seat is arranged on the top of an oil sleeve on the oil hole. The integral sliding bearing is simple in structure, but the bearing clearance can not be adjusted when the working surface of the bearing is too large. The journal can only be loaded from the end. Split sliding bearings are mainly composed of bearing housings, bearing housings, split upper and lower bearings.

Q: What is a sliding bearing alloy?: 3, enough plasticity and toughness, higher fatigue strength; 4, good heat resistance grade corrosion resistance; 5, good running in.

Q: What are the requirements for the material performance of plain bearings?: When the machine does not work, the axle is resting on the bearing and exerts pressure on the bearing. When the shaft rotates at a high speed, the shaft to the bearing with periodically varying load, sometimes accompanied by shock. The basic function of plain bearings is to accurately locate the shaft and to support the shaft without damaging it under load. Shafts usually cost higher and are often uneconomical to replace. Selecting the bearing alloy that meets certain performance requirements can guarantee the minimum wear of the shaft.

Q: What are the major damage forms of plain bearings?: A: the main types of damage to the pulley bearings are: 1, glued bearings overheating, excessive load, improper operation or temperature control system failure.2. Fatigue failure caused by unbalanced vibration, shaft deflection and edge load, overload and so on, lead to fatigue rupture of babbit. Bearing repair and installation quality is not high.3, because the grease dirt nap of large particles into the bearing gap, and embedded in the bearing bushings, bearing and shaft neck (or thrust plate) contact, hard callus formation on the surface, it will seriously scratch the shaft, bearing oil picking attention clean, especially in maintenance we should pay attention to, metal scraps or dirt and scratches due to wear clean lubricating oil mixed with impurities, dirt and foreign matter. The repair method is wrong and the installation is wrong. Improper use and maintenance, poor quality control.

Q: How is the oil groove of the plain bearing processed?Boring, milling, or other methods of processing?What's the difference between oil grooves with different inner diameters?: 1, with the processing of internal thread processing. 2. Pull out with a broach. 3. Pull out with special machine tools.

Q: What are the aspects of the performance of plain bearing materials?: The material selection of the sliding bearing depends on the form of failure. The main failure modes are wear and fatigue damage of bearings and shafts. The prevention of wear and fatigue damage of bearings and bushings is the key to the selection of bearings and bushings. The main considerations are as follows:Wear resistance and friction reduction;Running in (running fit);Hiding property;Compliance;Strength and plasticity;The heat transfer and good corrosion resistance;The process of economy, etc..

Q: Which is good, rolling or sliding bearings?: Rolling bearings and sliding bearings for different occasions, can not simply say good or bad.Different structures of sliding bearing is on the smooth surface to support the rotating shaft, which is a surface contact area; rolling bearing by rotation of the rolling body to support the rotating shaft, which is a point of contact area, rolling contact more, more.The motion mode of rolling bearings is rolling, the movement of sliding bearings is sliding, so the form of friction is completely different.Plain bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, and the friction loss and surface wear can be greatly reduced, and the oil film also has a certain vibration absorption capacity. But the starting friction resistance is larger.

Q: Effect of bearing speed on oil film stiffness of journal bearings: Of course, the faster the turn, the greater the impact!

Q: What are the properties of plain bearing materials? Are there any materials that can satisfy these properties simultaneously?: 4. thrust bearing (understand) (1) thrust bearing fixed and tilting. (2) the thrust surface of thrust bearing can use the end surface of the shaft, or can make a convex shoulder or thrust the disc in the middle of the shaft. (two) the types and characteristics of rolling bearings; 1. classification of rolling bearings according to the shape of the rolling body is divided into: ball bearings, roller bearings. 2. characteristics of rolling bearings (1) advantages: compared with plain bearings, rolling bearings have the advantages of small friction resistance, quick starting, high efficiency, simple lubrication and easy replacement. (2) disadvantages: poor shock resistance, noise at high speed and long service life, as opposed to liquid lubricated sliding bearings.

Q: What are the main structures of radial plain bearings? What are their respective features?: The integral type bearing has simple structureThe mounting surface of the flange type bearing is perpendicular to the central line of the bearing
