Be careful !！Six big failure of bearings

 

Bearing is the core part of mechanical . We can check the fault of bearing timely to ensure the normal operation of machinery.Now let's look at six big failure of bearings.

1.Fatigue
Bearing fatigue is characterized by spalling of bearing raceway.This is because the strength of the bearing steel particles decreases, causing the particles to peel off the raceway.The surface of the cracked bearing is rough, which will produce noise and vibration.

Normal fatigue damage occurs when the bearing reaches its expected life under normal load and working conditions.This form of damage is predictable and is caused by metal damage under continuous load.

What's the Application of taper roller bearing in fan gearboxes?

FRB BEARINGS tapered roller bearing in the application of fan gear box method you understand?Fan gear box design is various, but basically all by row star and row class composition.A planet carrier is now more common input, internal gear ring fixation, sun wheel output and pass to the parallel level design as an example, the analysis of common bearing failure modes and the corresponding solutions.

What is the difference between low carbon steel and carbon steel?

To buy bearings, you must choose the right material.First of all, we need to understand the properties of materials so that we can better choose and use them.

Low carbon steel annealing is ferrite and a small amount of pearlite, with low strength and hardness, good plasticity and toughness.Therefore, its cold forming is good, it can be cold formed by winding, bending, pressing and so on.This kind of steel also has good weldability.Carbon content from 0.10% to 0.30% low carbon steel is easy to accept various processing such as forging, welding and cutting, often used in manufacturing chains, rivets, bolts, shafts, etc.

High precision cross roller bearing processing problems and how to use?

High precision cross roller bearing with the development of science and industry is a necessary part of machinery equipment.The cross - roller bearing processing is to be designed.So what are the design tips for micro machining accuracy?The biggest cause of bearing damage may be severe friction, fatigue and pressure melting.Therefore, the design of friction in bearing machining precision should pay attention to a lot of techniques.The superfinishing sequence of cross roller bearings can be divided into three steps: cutting, semi-cutting and finishing.FRB BEARINGS will detailed introduce the process of crossed roller bearings.

Application of anticorrosion technology on slewing bearings

A wind power equipment company requires its wind power equipment on the slewing bearings of anti-corrosion more than 20 years.There are two main antiseptic methods for the slewing ring of wind generator.The other is the technology of spraying zinc with antiseptic coating.This paper mainly studies and analyzes the application of the two anticorrosion methods in the slewing  ring.

Research and treatment method of bearing damage for vibrating screen in mining machinery equipment

Dynamic screen is a common equipment in mining machinery, and its vibration is mainly realized by exciter.The exciter forms are diverse, and the widely used eccentric-block external structure has the characteristics of light weight, compact structure, lubrication concentration of transmission parts, convenient maintenance and low manufacturing cost.However, there is a general problem in this structure, that is, the bearing life in the exciter is short, and the bearing heating and burning loss often occur, which seriously affects the normal operation of the vibrating screen.

The operating condition of the exciter is harsh, not only the environment humidity is large, the dust is much, the speed is high (750~1400r/min), and there is a strong vibration impact.After practical experience, the main bearing damage is:

What about the bearing damage of the feeder?

Feeder is often used in electrical hardware accessories, computer hardware accessories, mobile phones hardware accessories, digital products hardware accessories before stamping leveling work, only by leveling, can produce qualified five parts, so the feeder is indispensable to the production of stamping production equipment, the whole even some beyond the scope of the plate material, although a short period of time is no problem, but a long time light can cause roller bearing damage, can cause roller or motor damage, caused to halt or delay of production, if the bearing damage as long as in the following steps, can own in a timely manner to solve, which does not affect the production schedule:

How to select high precision cross roller bearing and YRT turntable bearing?

YRT turntable bearing is a rotary mechanism of outer ring and inner ring support. It is mainly divided into three series: YRT, YRTS and YRTM.How to select high precision cross roller bearing and YRT turntable bearing?

The space of the cross roller bearing can be constrained.In most cases, the axis (or cross roller bearing inner ring) is based on mechanical or other delineation constraints.Therefore, the selection of cross roller bearing type and scale is based on the internal diameter of cross roller bearing.Therefore, the first scale of the standard cross roller bearing is based on the international standard.
Specification method of heavy and complicated of the scale of the cross roller bearing, the best choose on machinery and equipment, standard cross roller bearings,cross roller bearing load on the cross on the roller bearing load, the nature, intrusive, direction is changeable.In general, the extra basic load is shown on the scale.However, axial load and radial load are also important factors for selecting suitable cross roller bearings.When the ball and needle bearing are at the same time, the cross roller bearings generally have higher load capacity and accept larger oscillations and impact loads.

What’s the application analysis of cylindrical roller bearing on high-speed machine?

FRB BEARINGS is specialized in the large and super large bearings and YRT Rotary bearings, precision crossed cylindrical roller bearing, crossed tapered roller bearings,thin-walled ball bearing production,research and development for the integration of high-tech enterprises.
