Troubleshooting damage to the first shaft and rear bearing of the transmission

<p>The method of grinding steel ball using a grinding wheel in ball milling machine after heat treatment is called hard grinding, its function is to eliminate the defects of soft grinding (or light grinding), remove the surface oxidation, decarburization, deformation and troostite structure flaws generated from the heat treatment, and further enhance the precision and surface quality.In the process of metal ball hard grinding or after the end, the look ought to be checked for surface flaws, after cold pickling check burns, burns could be generally divided into secondary tempering burns and secondary quenching burns, secondary tempering burns following cold pickling black, secondary quenching burns after cold pickling centre is grey martensite, surrounded by black troostite.There are linear burns, and spot burns and menopausal burns (large ball burns).Reasons for linear burns:1.&nbsp;2.&nbsp;3.&nbsp;The groove of cast iron disc or grinding wheel Doesn't match;4.&nbsp;The junction between distributor and cast iron plate is not consistent;5.&nbsp;The bell mouth in the back of the cast iron disc is too wide, so the steel ball contacts the edge of the grinding wheel groove;6.&nbsp;Improper adjustment of the gradient of this ball groove makes the steel ball flow too fast or too slow;7.&nbsp;8.&nbsp;The ball suction Angle of the ball amassing blade is worn or flat to a concave shape, and chunk gathering Isn't smooth;Improper application of work tension. After driving 40,000 kilometers, the first shaft of the transmission back bearing (50306#) was ruined continuously.In the process of troubleshooting this error, several disassembly and inspection of transmission, no strange phenomenon was found;Measuring torsion bar spring adjusting screw, the height is 42mm, according to the standard;Check that the job of the spline between the torsion bar spring along with the arms in both ends -- disassemble both pull pubs, and there is no problem. Only the abandoned torsion rod spring adjustment screw and the rubber pad between the back fixing arm are damaged, after replacing the rubber mat, troubleshooting.So far, it's traveled over 5,000 kilometers, and the posture still works normally.CA6440 light passenger automobile, the front suspension adopts the perpendicular torsion bar type spring independent suspension, and this can be connected with the framework and steering knuckle through the linking bar.The torsion bar spring is connected with the lower control arm throughout the torsion arm, and the lower control arm is connected with the frame during the front beam to form the front support.The torsion bar spring is linked to the transmission supporting beam throughout the adjusting arm along with adjusting screw, and the transmission behind beam is connected to the frame to shape the encouraging beam.Forces and torques in most directions are transmitted from the linking rod system and torsional torques are sustained from the torsion rod spring.In the practice of forcing, when the front wheels meet the horizontal impact force, front brakes and steering knuckles are transmitted into the transmission service beam and frame throughout the torsion bar spring.When front wheel experiences the impact force from the vertical direction, the front suspension is changed into the torsional moment through the torsion bar spring, that can be transmitted to the transmission service beam and the frame.The power of all sorts of impact force and torque endured by the front wheel is gradually consumed by the bicycle, shock absorber, steering knuckle, tie rod spring, and transmission beam and framework, so as to guarantee the smoothness and safety of the vehicle.In sequence to permit the front wheels on both sides to effectively absorb and absorb the forces and torques in each direction, a certain pre-torque force ought to be added when installing the torsion bar spring.This pre-torque is equal to a huge spring and is employed in conjunction with the shock absorber into de-energizes, while effectively absorbing the energy generated by the forces and torques in the front wheels in most directions.In order to generate the two spring torsion bars have the exact same pre-torsion force, the setup and adjustment of the torsion bar spring must be in strict compliance with the technical criteria, in order to ensure that both front wheels in the practice of transmission torque and force and energy absorption to attain a balance.The car's pole spring adjusting screw rubber pad ruined, although the car in static, the elevation of the adjusting screw is the same, but it is equal to increase the length of the left pole spring adjusting screw, is equivalent to decrease the pretorque of the left torsion pole spring.In the process of auto motion, the applicable parts will be unequal and out of balance when shifting force and moment and absorbing and swallowing energy.The transmission is directly connected to a beam that transmits forces and torques in the front brakes and absorbs electricity, as well as forces and torques between the motor and the drive axle.Therefore, tie rod spring adjustment screw rubber gasket harm, unilateral transmission in the process of loading, the level of the"unbalanced" increases, and one of the results of this"imbalance" function, is to make the first connected to the transmission and the main areas of the engine, transmission shaft"foorn" bad, stress points will focus on supporting both before and after the transmission of the first shaft bearing.The front bearing is the sleeve type sliding bearing, the rear bearing is that the <a href="https://www.wxingbearing.com/" target="_blank">roller bearing</a>&nbsp;, the sliding bearing is bigger than the rolling bearing immunity, but the anti-destructive force is powerful, therefore led to the transmission first shaft after the constant damage of the posture.</p>
