The forklift starter is an important part of the forklift, and its normal operation is essential for the start and operation of the forklift. However, there are times when the forklift starter may have abnormal sounds, which can be caused by a number of reasons.
First of all, when the drive gear of the starter is not engaged in the gear ring, the main circuit of the starter will be turned on, causing the starter to make a "click" sound. This is due to the fact that the drive gear of the starter is not fully engaged with the flywheel tooth ring, making the starter not work properly.
Secondly, when the drive gear and the flywheel tooth ring are on top of each other, the main circuit of the starter will also be turned on, resulting in a "rattling" sound from the starter. This is due to the problem that there is a gap between the drive gear and the flywheel tooth ring that is too small or uneven, so that the drive gear cannot mesh properly.
In addition, loose fixing bolts may cause the starter to make an abnormal sound. This is due to loose fixing bolts that can cause the starter to be mounted in a deflected position, preventing the drive gear from fully engaging with the flywheel tooth ring.
In addition to this, other causes can also cause the starter to make abnormal sounds. For example, the distance between the end face of the drive gear and the end cover edge does not meet the requirements, the one-way meshing is slipping or damaged, the shock absorbing spring is broken, the rotor and stator are rubbed, the magnetic field coil or armature coil winding has a local short circuit, the bearing is too loose to make the armature and the magnetic pole collide, and the excitation or armature winding has a local short circuit.
In conclusion, there can be many reasons for the abnormal sound of the forklift starter, which needs to be checked and resolved on a case-by-case basis. If abnormal sound is found in the starter, stop using it immediately and ask a professional to overhaul and repair.
