Bearing choice: the frequency of the tapered roller bearing calculation

NSK bearings in theory when zero clearance noise and have reached the state of beautiful life, but in actual operation considering the problems such as temperature, NSK bearing clearance for after assembly. When rotating too tight, Set set of tighten too far) ； Bearing noise ( The roller face or steel skid) ； Excessive axial thermal elongation ( Axial additional load bearing is statically indeterminate) ; Shoulder is too big, The bearing seal and friction) ； Holes of the block shoulder is too big, Send the bearing seal touch misrepresenting) ； Labyrinth seal gap is too small ( With the shaft friction) ； Lock washer tooth bending ( The bearings and friction) ； Left the position of the oil ring is not appropriate ( The flange cover and friction) ； On the ball or roller pressure pit ( Installed with a hammer bearing caused by) ； Bearing noise ( There are foreign source interference) ； Bearing and deformation (heated Use the spray heat sealed bearing caused by) ； Shaft is too coarse to make actual fit too tight ( Cause the bearing temperature too high or noise) ； Small diameter of hole, Cause high bearing temperature) ； Bearing hole diameter is too large. Sauvy materials and application technology can make the enterprise in the first time quick and efficient on-site repair, effectively avoid the equipment downtime for a long time, production and the benefits of losses; Effectively avoid shipping costs, hoisting construction costs and security aspects of the comprehensive factors, to ensure the personal safety and enterprise loss, saves valuable production time for the enterprise. Between the surface of the wear failure wear failure refers to the relative sliding friction lead to constant wear and tear of the working surface of the metal and the failure. Axial axialchamferdimen - chamfer size Methyl amino acetonitrile sion - Methyl amino acetonitrile ring or washer hypothetical Angle to the ring or washer on external surface of the inner hole or the distance between the intersection curve with the chamfer surface. Lock washer tooth bending ( The bearings and friction) ； , sealed bearing or bearing with dust cover, after long-term storage, the lubrication characteristics of bearing grease filling in May reduce. Unable to start or amplitude small motor or electrical components damage first check, if the motor damage need to change; Second check control circuit of electric components, such as electrical components damage will be expected to replace the electrical components. Under the bearing installed on the crankshaft bearing cover, installation shall not apply the oil on the surface of the bearing contact with bearing cover. Bearing insulation from cover while under insulation distance is zero. So the stand or fall of an engine, rotary spindle bearings used in the precision is not high, due to the groove wall thickness difference, waviness, not poor roundness and the size of the rolling element and cause vibration. Work environment cleanliness, group eccentric block quality difference, or group of eccentric block installation Angle error is bigger, cause vibration source center, fever caused by bearing, roller bearing instructions, installation, first level measurement basis level, such as uneven can be adjusted by means of plate on foundation. The CSB - such as common in the market at present LIN plastic linear bearing is materials after lubricant and enhance fiber modified engineering plastics, the wear-resisting performance is very out; Due to plastic sliding bearing is metal sliding bearing has many advantages, the production of plastic bearing is growing, the use of plastic bearing situation is outspread, from fitness equipment to the office equipment and automobile industry, and so on all use plastic bearings, car without driving on the highway now use plastic bearings. Design reason, also because of the bearing ring wall is thin, bearing inner and outer ring is easy deformation, the inner ring guard can be used without slot structure, but to strictly control the seal clearance.
