The Main Reason Of Failure Hammer(c)
Post Time: 2016-07-13
If there is a rotation of the hammer can not hear the voice compression rod may be broken off or eccentric.
If the motor has rotated the hammer does not turn too uncompressed sound or noise power has great gear One gear it may be damaged or broken shaft of the rotor.
Three drilling gear damage manifested as weakness or simply not turn. # 907 bearing aging can also cause damage to the gear III, expressed as normal drilling, withdraw a large hammer gear noise or not to switch.
There is also a phenomenon we should note that the bond breakage, when we checked with the gears and shafts, due to strong friction shafts and gears glued together, not easy to find bond cleavage, but to bring the load after not work properly.
Surface mechanical failure wide, not always an exception, generally in practice specific analysis.
Note: Before renewal parts, debris and oil must take the point of failure within the handle clean, so not only for us to discover the other faults, it will not cause secondary debris stuck gear malfunction.
Also: intermediate cover needle bearing (bearing # 688) must use the good, because after it is damaged, the damaged joint One gear and the rotor shaft.
