Impact on mechanical wear of physical property of the grease


14th December 2013 Bearing Technology 1 Comment
Abrade while being what is called, refer to the intersection of antithesis and surface of movement pair the intersection of work and external material lose or produce course of residual deformation constantly at the relative motion. It is mainly the mechanical function because among the surfaces of antithesis to abrade the course, return sometimes in addition, the chemical action is produced. Usually this mechanical function refers to tribological function, and the chemical action often refers to the erosion effect of environmental mediums and chemistries. When grease lubricate, lubricate ...

Must pay attention to the basic item in storage of the grease


14th December 2013 Bearing Technology 0 Comments
When the grease rubs against others to lubricate in the bearing on the part, it is the solid friction that substituted with its internal friction between the friction surfaces of parts. So, the degree of viscosity of the grease has very great influence in using the mechanical power consumption of the grease. If the grease used is relatively large in viscosity, obviously there will be more friction losses. The degree of viscosity of grease, with cutting the properties of changing rapidly, make it have special adaptability while using on the machinery that the speed often change. When the speed ...

Maintenance technological analysis of the industry koyo cylindrical roller bearing


14th December 2013 Bearing Technology 0 Comments
In order to maintain the original characteristic of the cylindrical roller bearing with the good state as for a long time as possible, must maintain, overhaul, so that accident proof on right, guarantee reliability that turn round, improve productive, economy. Maintain the operation or work standard of the condition of operating of preferably corresponding machinery, go on regularly. The content includes the inspection that monitors the running condition, supplements or changes lubricant, dismantles regularly. As overhauling the item in operation, there are rotatory sound, the states of the ...

Prevent spoiled maintenance method too early of KOYO thrust ball bearing


14th December 2013 Bearing Technology 1 Comment
Need the surface of the clean machine first before checking, then dismantled the perimetral part of KOYO bearing. Oil seal fragile part very, take careful dismantlement, make sure not excessive application of force, then checking oil seal and perimetral part carefully, while already demonstrating bad symptom, must change, the bad oil seal will result in importing the damage of the bearing and apparatus had severely and shutting down. Check lubricant, stained with small lubricant to rub in two when points, if there is pollutant that exists, can feel, or in a lamina of lubricant of final ...

Getting rid of the maintenance which is overhauled the grease differently and loudly of koyo major groove ball bearing


14th December 2013 Bearing Technology 1 Comment
In order to judge whether koyo bearing dismantled can be reused, should check after ball bearing is washed clean in the major groove, check the surface of ball track meticulously, rolling surface, cooperating with the abrasion situations of Taxi state, retainer, increase of the bearing backlash and having damage regarding size accuracy drops, unusual. It is not a small ball bearing of separate type, support competence of the inner circle with a hand, rotate the outer lane to confirm whether it is smooth or not. Koyo bearing,etc. separates the shape bearing, can check to the ball track ...

Koyo stainless steel bearing turn round and check and maintain the method at ordinary times while being carefree


14th December 2013 Bearing Technology 0 Comments
Koyo bearing is because of one's own quality and reason of the external condition in the course of using, its bearing capacity, rotating precision and wear-resisting characteristic to change in a moment. When the performance index of the stainless steel bearing can't work normally while lower than the instructions for using, the bearing breaks down even fails, once koyo bearing fails after unexpected situation, the machine, apparatus will be stalled, various abnormal phenomenas of losing the function etc., so need to find the reason to happen in a short time, and take the corresponding ...

The backlash of the antifriction bearing is determined with choosing and attentive matters


14th December 2013 Bearing Technology 0 Comments
Principle and method that the backlash of the bearing measures The intersection of bearing and radial backlash it measures to be fixed inner circle or outer lane, it exerts to be can until examining value measure load steadily on the unfixable collar, and do the reciprocal movement on the basis of diameter direction to measure. Put the intersection of side and hair to the unfixable collar width, read the shifting quantity along load direction on position of all angles of the unfixable collar, its arithmetic mean is a radial backlash value of a bearing. Backlash of the antifriction bearing ...

The major cause of the corrosion of the antifriction bearing and work of antirusting of the bearing


14th December 2013 Bearing Technology 1 Comment
The major cause of the corrosion of the antifriction bearing and work of antirusting of the bearing: Drench the gushing out type and antirust, management is more convenient, save labour force again, the middle storehouse antirusted with 2 individuals unable to finish in the past, use a person's other work of being as now, also very prominent according to result of antirusting. To 7002136 and 3620 friction roller 4000 more than, adopt, drench person who gush out, antirust, insist very much bright still in more than one year nearly in will it be March 2003, there is no corrosion. In addition ...
