1. The part where the lower tie rod of the ripper is connected to the working beam is subjected to excessive force, which may cause plastic deformation or even cracks after long-term operation. Therefore, it is necessary to strengthen the outer steel plate thickness. At the same time, the stress is more concentrated on the stronger part in the middle of the tie rod.
2. The loosening teeth are made of alloy steel with higher strength. The stress situation is not obvious and can basically meet the working condition requirements. But you need to pay attention to the connection between the tooth tip and the guard plate.
3. The bracket is installed on the tail of the bulldozer. The part connected to the tail is subject to greater stress. Moreover, the connecting hole is also subject to the reverse thrust of the hydraulic cylinder. Therefore, adding a transverse support plate to the point where the stress is greatest can solve this problem.
4. The connection between the upper end of the working beam and the hydraulic cylinder is subject to the greatest stress. It is prone to fatigue damage, so alloy steel materials with higher yield strength need to be selected. In addition, the connection between the pipe beam and the gear sleeve of the working beam is also subject to greater stress, and the material welding process requirements for this part are relatively high.
