Carbon steel bearings, car wheel bearings why always bad

The temperature of the bearing to hope degrees) , shall be immediately removed from the slot, and quickly into the shaft, bearings will be along with the temperature drop and shrinkage, sometimes between shoulder and bearing face, will produce gap, therefore, need to use tools, the bearing axis direction compression. Due to preload changes have less effect on the contact load, the centrifugal force change on the influence of the stiffness is very small, so the ball diameter under constant pressure preload, ball diameter radial stiffness increases, the axial Angle stiffness and reduce, but less affected. Electrical protection - — Overload protector ( Quick fuse overcurrent relay) Mechanical protection - — Safety pin or security key, when overload, first cut pin or keys, protection. Bearing damage analysis of the cause of the first because of the way for a long time to take two roller diagonal to run two roll as a standby, so lead to two backup rolls inside the mill, tilt hanging for a long time, Is the two main oil cylinder as support) 。 Improve the installation method: cleaning related parts, N type and NU type axial movement, can adapt to the shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing. Oil pressure is too low, lead to the oil in the oil chamber for a long time, in the process of shaft operation result in higher temperature, resulting in high pressure caused by oil mist; Oil pressure is too high, can make the oil return ability is insufficient, and large amount of oil in the oil chamber of the oil level is too high to increase the internal pressure. The performance of the lubricating oil selection: viscosity - — Represent the flow of liquid in the size of the internal friction resistance, is an important performance index, and choose the main basis of lubricating oil. C < P <, reciprocating piston is through the piston within the cylinder for reciprocating motion change working gas volume; Piston compressor has a long history and mature production technology. & emsp; & emsp; Analysis: the bearing life is longer than the bearing, bearing cataclastic driven pumps cannot work; The bearing and the bearing cavity filled with coal cinder is, sand and water bearing under rapid failure of the direct and main reason; Bearing and bearing cavity filled with coal cinder, sand and water is derived from the motor chamber, such as motor cavity working condition of coal cinder, sand, etc from water, the reason is the skeleton oil seal & amp; emsp; & emsp; Such as the wear failure. Could you talk about vibration motor with the bearing? What is a good type of series vibrating motor selection? How to better when installation? Maintenance and repair which aspects should pay attention to? Answer: vibrating motor, is a very interesting topic. Relative inner ring rotating eccentric sleeve with the inner ring is tight, then tighten the top wire binding on the shaft, add heat quenching vacuum, vacuum and low pressure carburizing, nitriding, nitrogen and carbon altogether permeability and boriding can obviously improve quality, reduce the distortion and improve life. Or maintenance time, if the stress is not, will cause the steel after the set time, or in the subsequent machining deformation or crack produces in the process, to car maintenance, and fuel for quenching medium is only applicable to the stability of the supercooled austenite of some steel alloy or carbon steel workpiece quenching of small sizes.
