Bearing heating: how soar team rear wheel bearing

Before some post code with basic code separated by dots, SP - — Dimension precision is equivalent to level, rotary precision is equivalent to level ( Double row cylindrical roller bearing) 。 Connect the E end of the instrument and rotor; The insulation of the bearing parts, Such as the outer ring) Cover with aluminum foil, foil with copper wire binding is fixed, and then connected to the instrument L end; Or insulation bearing load bearing or motor end cover bearing chamber, the bearing or the motor end cover and install the insulation bearing rotor without electricity access conditions, measurement of the insulation resistance between shaft and bearing seat or the motor end cover. Question tabled reason and solution: water pump motor power trip if the matching power suddenly protector are consistent with the water pump motor, under normal circumstances, the protector is not trip. But generally speaking, most usually bearing fracture failure for overload failure, failure of object and background material to collect as much as possible to collect the failure parts and pieces of things. The first step, the vehicle with lifting machine up, dangling the wheel and loosen the hand brake; The first step, the driving wheel, can be manually by arrive slow fast rotating wheels, check whether there is bearing noise; The first step, when the test drive wheels, launch vehicle idler wheel, to check whether there is additional bearing noise. Choose V specifications of the insulation resistance meter, the use of sliding bearing and rolling bearing motor, such as not according to the above method, can adopt the method of shaft placed on current transformer measurement shaft current. If outside dirt inside the bearing seat, pollution is near the outer grease, first make the bearing parts surface wear, roller, raceway dent, the phenomenon such as pitting, change according to specific situation. Countermeasures: grinding trunnion, get appropriate coordination between the shaft and bearing inner ring, due to the material of bearing box hole stress after the aperture is too soft, cause the outer ring hole slippage in box. Avoid direct contact between the metal, when two contact bodies is formed between the surface of the electrostatic potential difference, high enough to be breakdown when the insulation layer, can produce spark discharge, forming a current erosion phenomenon. The first hammer assembly, obtained by contact velocity or acceleration sensor, a fixed on the bearing cover directly or through magnetic adsorption on it, is sometimes called a shell vibration, vibration. In cone gear speed reducer, for small bevel gear shaft, cantilever requirements with good rigidity, and can adjust the axial position of the axis, two gear cone roof overlap in order to achieve. These qualities make the aluminum alloy in some fields instead of more expensive bearing alloy and bronze, in addition, the adsorption hydrocarbon, graphite can help to improve the performance of boundary lubrication is adopted gray cast iron bearing material, should add lubricating oil.
