What defects should be had on quality that part of the bearing is hot and treated? 1.Overheated Can observe after quenching organize overheatedly while being micro- at the intersection of bearing and the intersection of part and coarse mouth. Want precise to judge his overheated intensity must observe micro- organization. If horse's body of thick needle appears while organizing in the quenching in GCr15 steel, in order to quench the overheated tissue. Forming the reason may be caused by quenching the heating temperature too high or heating temperature retention time too long overallly and ...

The repair skill of the close shaft hole of the bearing explains: 1Measure the shaft hole abrasion depth, if the abrasion depth is smaller than 4mm namely the radius direction is smaller than 2mm in the diameter direction ,Employ the electric tool to wait to repair the location to polish and strengthen. Attention: The surface mustn't be rubed too smooth, the more coarse the better. 2New 1755 cleaner wash the intersection of bearing and hole, wait to build the surface with can have a match. 3Paint one can have a match new 1731 the intersection of drawing of patterns and pharmaceutical while ...

Bearing sealed technical research and sealed bearing quality current situation: Main research contents and current situation with low quality of sealing the bearing of the goal according to China at present, the main research contents will be in the future: Study and test at first, and select the sealing of the deep ditch ball bearing and enclose the structure and develop the inner circle seal groove structure of the corresponding bearing, carry on the update that the current deep ditch ball bearing sealed the structure, try to make this kind of bearing sealing property keep abreast of the ...

The rectilinear motion bearing is a kind of rectilinear motion system by low-cost production, used in the limitless journey and use with round axis of a cylinder. Because of bear the weight of ball with axle, present, order, keep in touch, use load to be little. The steel ball is rotated with minimum friction resistance, thus can obtain the steady sports of high precision. Series Normal form LM/LME/LMB.. UU , adjusting type LM/ LME.. UUAJ , the style of opening LM/LME.. UUOP ; Extending type LM/LME.. LUU ; Flange type LMF/LMK/LMH.. UU, LMEF/LMEK.. UU , flange extending type LMF/LMK/LMH.. ...

Import the commonly used heating method main point of the bearing: The commonly used heating method is as follows, to import the bearing 1,Oil groove heating law: 1 This employs wider traditional heating method, the oil slot pitch bottom 50-70mm place sets up the metal network, it is on net that the bearing locates in, the big bearing should be hoisted out with the hook. Inquire about the system in bearing type of the car 2 The bearing should not be put at the bottom of the trough directly, is heated too high so as not to contact the bearing position part of the bottom of trough, or the ...

The installation method main point that the rolling bearing heats: Heat the main point of installing law: The temperature heated should be controlled properly, the temperature too high bearing will be damaged, the expansion of one set of circles of hypothermia is insufficient, the result is not prominent. 80- The intersection of heating and the intersection of temperature and resulting the intersection of inner circle and the intersection of heat and expansion of internal diameter of 1000 ℃, this generally over to full of bearing of quantity for to have speech, it is enough. Inquire about ...

Chinese car bearing network bearing classroom: Deep ditch ball bearing easy to use simple in construction, the intersection of production lot and most large, the intersection of range of application and widest kind of bearing. It is mainly used to bear the radial load, can also bear certain axial load. When the radial backlash of the bearing is strengthened, have function that angles are exposed to the ball bearing, can bear and teach the large axial load. Compared with other types bearing the same in size, this kind of bearing rubs the factor small, the terminal rotational speed is high. ...

Chinese car bearing network bearing classroom: Lubricate extremely important influence. Here is chosen the general principle of lubricating grease to your brief introduction. Lubricating grease is made of basic oil, thickening agent and additive, lubricating grease performance of different kind and different trade marks of the same kind differs greatly, the rotatory limit allowed is different, must notice in the choice. The performance of lubricating grease is mainly decided by basic oil. The basic oil of the general low viscosity is suitable for the low temperature, high speed; High ...

The surface of the bearing applies and antirusts the oil, you must wash carefully with the clean petrol or kerosene, and then spreading the clean and high-quality or with high-temperature high speed lubricated oil can be installed and used. It is very great to clean degree to bearing life-span and influence of shaking the noise. But we should especially remind you: The totally closed bearing need not be washed and refueled. ...
