Environment: the use of a, KOYO bearing according to the area of use and conditions of use and environmental conditions choose size, precision, with appropriate bearing is the prerequisite of KOYO bearing life and reliability.
1, use parts: tapered roller bearing is suitable for predominantly radial load under the combination of radial and axial load, usually in two sets of matching using KOYO bearing, mainly should be in the car before and after the wheel hub, active transmission parts, such as bevel gear, differential, reducer.
2, allows speed: under the correct installation, lubrication good environment, allowing for KOYO bearing limit speed of 0.
3 -
0.
5 times.
Generally under normal circumstances, with 0.
2 times the limit speed for the most appropriate.
3, allows tilt Angle: taper roller bearings are generally not allowed to have tilted axis relative to the shell hole, if there are any tilt, no more than 2 '.
4, allow temperature: under normal load, and lubricant has a high temperature resistant performance, and abundant lubrication conditions, general KOYO bearing in - are allowed
30℃-
Work under the temperature 150 ℃.
Second, KOYO bearing installation: installation of KOYO bearing must be conducted in a dry, clean environment conditions.
Before installation should carefully check the shaft and the shell surface, convex shoulder of end face and groove and the connection surface machining quality.
All matching connection surface must be carefully cleaned and remove burrs, rough surface must remove all sand castings.
KOYO bearing should be taken before installation with petrol or kerosene wash clean, dry after use, and to ensure good lubrication, KOYO bearing grease lubrication, commonly used oil lubrication may be adopted.
Using grease lubrication, should choose without impurities, antioxidant, antirust, superior performance, such as extreme pressure grease.
Grease filling quantity for bearings and bearing box - 30% of the volume
60%, unfavorable and overmuch.
With sealing structure of double row tapered roller bearing and water pump shaft bearing has good filling grease, users can directly use, shall not be clean.
KOYO bearing installation, it must be in the ring width on the circumference of a circle of equal pressure, to press the ring into, can not use ð ¨ + face top tools direct percussion KOYO bearing, so as to avoid damage KOYO
In the case of a small amount of interference, but at room temperature with the sleeve pin KOYO bearing ring end face, with a ð ¨ + head banging on sleeve, through the sleeve ring is balanced
If large quantities of installation, can use hydraulic press.
Fashionable, should guarantee the outer end face and the shell shoulder end face, inner ring end face and the shaft shoulder end face pressure, there is no gap.
When large amounts of interference, can use oil bath heating or sensors heating method to install the KOYO bearing, heating temperature range of 80 ℃ -
More than 120 ℃, 100 ℃, the highest can't.
At the same time, the application of nut tighten KOYO bearings, or other appropriate method to prevent the bearing width after cooling contraction and make the clearance between the ring and the shaft shoulder.
Single row tapered roller bearing installed last should undertake clearance adjustment.
Clearance value should be used according to different conditions and cooperate with the amount of interference and specify the size.
When necessary, shall be tested to determine.
Double row circular cone roller bearings and pump shaft KOYO bearing in have been adjusted when delivery from factory clearance, installation time don't have to adjust.
KOYO bearing test should rotate after installation, first used in the axis of rotation or KOYO bearing box, without exception, with a power of no load, low speed, then according to the condition of operation gradually increase the speed and load, and detection noise, vibration and temperature rise, found abnormal, should stop and check.
Running test normal rear deliverables.
Three, KOYO bearings: removal of KOYO bearings removed after plans to continue to use, should choose the proper removal tool.
Remove the interference fit ring, can only add tension on the ring, will never allow through transfer roller disassembly force, rolling element and raceway will be crushed.
