First, bearing installation: bearing installation must be in a dry, clean environment conditions. Before installation should carefully check the shaft and the shell with surface, convex shoulder of end, grooves and connection of surface processing quality. All connected with surface must be careful cleaning and remove burr, casting unprocessed surface must be free green sand.

Before installation should use first bearing gasoline or kerosene clean, dry after use, and provide good lubrication, bearing general use of the grease lubrication, also can use oil lubrication. The grease lubrication, should choose without impurities, oxidation, rust and extreme pressure and the superior performance of grease. Grease filling quantity for bearing and bearing capacity box of 30% to 60%, unfavorable and overmuch. Take sealing structure of the double row circular cone roller bearings and water pump shaft bearings has grease filling even good, the user can use directly, and not to do the washing.

Bearing when installed, must be in the ring width of circles on the equal pressure, will be pressed into the collar, and shall not use Lang top tool directly knock bearing end, to avoid the damage of bearing. In a surplus quantity is smaller, at room temperatures sleeve bearing pressure with live ring width, with Lang head beat sleeve, through the sleeve will balance pressure into the collar. If large quantities of installation, can be made hydraulic press. Pressure fashionable, shall ensure that outer shell with a shoulder end face, inner ring end face and shaft shoulder end machine pressure, does not allow to have the gap.

When a large surplus quantity, can be made oil bath heating or heating method to install sensors bearing, the heating temperature range for 80 ℃-100 ℃, the highest should not exceed 120 ℃. At the same time, the application of nuts or other appropriate methods to tighten bearing, in order to prevent the bearings after cooling contraction and make the collar width and shaft shoulder produce clearance

The single row circular cone roller bearings for clearance should be installed last adjustment. Clearance value should be based on the different operating conditions and the interference with the quantity and is specific and affirmatory. When necessary, shall be tested to determine. Double row circular cone roller bearings and water pump shaft bearing factory, has even in adjust clearance, when installation, don't have to adjust.

Bearings shall be installed on rotation experiment, first used in the axis or bearing box, if there is no abnormal, and to power without load, speed, and then depending on the operation situation gradually improve speed and load rotation, and testing noise, vibration and temperature, abnormal, should stop to run and inspection. Running test normal rear can put to use.

Second, bearing the disassembly: bearing tear open next to continue to use after, should choose the appropriate remove tool. Remove interference with rings, will only add in the tension on the collar, will never allow through the rolling body transfer remove force, or scroll body and groove will be crushed.

Third, bearing the use environment : according to use parts and the using conditions and the environmental condition choose size, accuracy and, together with the appropriate bearing is the guarantee bearing life and reliability of the premise.

1, use parts: tapered roller bearing applies to bear in radial direction load primarily radial and axial load of the joint, often in the two sets of bearing matching use, which should be in the car before and after the wheel hub, active bevel gears, differential gear reducer, transmission parts, etc.

2, allow speed: in the correct installation, good lubrication environment, allows for the bearing limit rotational speed of 0.3-0.5 times. General normal circumstance, to 0.2 times the speed limit for the most appropriate.

3, allow dip Angle: circular cone roller bearings generally don't allow axis is tilted relative housing holes, such as a tilt, the biggest not more than 2 '.

 
4, allow temperature: under normal load, and lubricant has high temperature resistant performance, and under the conditions of the abundant lubrication, general bearing allows 30 ℃-in-150 ℃ environment temperature.
