introduction：Ball bearings are a kind of rolling bearings,It is more common in light industrial machinery。Ball bearings are also called ball bearings。But ball bearings can not bear large heavy loads... Common equipment using ball bearings are：Motor drive shaft、light-duty（For civilian use）The transmission part of a motor vehicle、Machining equipment、Factory production line mechanical transmission assembly, etc。

introduction：The so-called ball screw，It is a transmission component commonly used in tool machinery and precision machinery，Its main function is to convert rotational motion into linear motion，Or convert torque into axial repeated force，High precision at the same time、Reversibility and rate characteristics。Because it has very little friction resistance，Ball screws are widely used in various industrial equipment and precision instruments。

introduction：We know that the wave gear reducer is a decelerating device，It consists of three basic building blocks：Fixed inner teeth rigid wheel、Flexible gear（That is, the elastic thin-walled sleeve cup connected with the matrix and the driven shaft“Make a tooth ring on the bus bar at the beginning of the flexwheel”）、And a wave generator that causes radial deformation of the flexwheel。In that way，We have a detailed understanding of the harmonic gear reducer it has what shortcomings？

introduction：TIMKENDeep groove ball bearing has simple structure，Easy to use and maintain。Mainly used to bear radial loads、It can also withstand a certain axial load，When the radial clearance of the bearing increases，It has the properties of angular contact ball bearings，Can withstand large axial load。The friction coefficient of this kind of bearing is small，Limit speed height，Varied in size range and form。

introduction：HRBBearing start time，The initial temperature rise is equal to high，After reaching the positive value，Gradually reduce and reach a stable temperature，This is because the inner ring conflict heat is higher than the outer ring when the bearing starts running，The inner ring expands faster than the outer ring，Why the running clearance is smaller than the residual clearance。Resume operation，Due to heat dissipation、The temperature of the outer ring is relatively stable，The running clearance is also stable，No number of conditions of bearing operation at the beginning of the control5min～6minIt can be inferred if there is an unusual temperature rise。

introduction：1、High speed The weight of ceramic material is only the same as that of steel４０％，The characteristic of low density，It can realize the lightweight and high-speed bearing，The ceramic bearing can inhibit the increase of rolling load and slippage caused by centrifugal force when rotating at high speed，The speed of ceramic bearing is steel bearing１．３～１．５times，itsＤＮValue reachability３００wan，For example, angular contact ball bearings，Because it has a certain contact Angle，There will be rotational sliding between the rolling element and the raceway surface，When using ceramic rolling element with low density，Not only rotating slide small，It also plays a beneficial role in bearing heating and surface damage，Its also very useful for aerospace vehicles。

introduction：1.Grease with impurities； 2.underlubrication(Low oil level，Improper storage causes oil or grease to leak through the seal)； 3.The bearing clearance is too small or too large(Plant problem)；
2018-11-22 Reading quantity 556
introduction：1、Bearing performance、Materials Because the ring and rolling body of the rolling bearing have to repeatedly withstand high contact pressure and rolling contact，Bearing retainer to withstand tension or compression force and sliding contact，Therefore, there are certain requirements for the material properties of each part of the bearing。
