Nowadays, the automobile industry continues to develop rapidly, not only reforming and innovating, and developing new energy vehicles, but also making the craftsmanship of previous models better and better. However, the quality of automobiles is also uneven. As one of the main means of transportation for modern people, in the process of rapid development, it is not only necessary to ensure that the output of automobiles is increased, but the quality and safety of automobiles are strictly controlled.
To understand how to improve the quality of the brake drum, one must understand the working principle and structure of the brake drum. In fact, the working principle of drum brakes is to use the brake transmission mechanism to make the brake shoes press the brake pads on the inside of the brake drum, thereby generating braking force, decelerating the wheels or stopping in a short distance as needed to ensure Safe driving, and ensure that the car parks reliably and cannot slip automatically.
In fact, after the working surface of the brake drum is assembled with the wheel hub, it needs to be positioned with bearing holes for finishing. The mini-car's requirements for the roundness and coaxiality tolerance of the working surface are ≤0.03mm, radial runout ≤0.05mm, and static unbalance ≤1.5N/cm. Therefore, if you want to achieve the above performance indicators, a brake drum balancing machine is needed.
If the brake drum detects the unbalance in the rotating state, it needs to remove the weight that affects its balancing according to the standard, which is what we call weight removal. Follow-up will need to retest the dynamic unbalance to reach the required brake drum accuracy level.
The brake drum automatic balancing machine produced by Shanghai Jianping can be automated from unbalance measurement, angle positioning, drilling weight removal and retest. This model has the characteristics of simple operation, convenient application and good accuracy. While balancing, it greatly improves work efficiency.
The instability of the brake drum requires the use of a fully automatic brake drum balancing machine. Shanghai Jianping has developed and produced balancing machines for nearly 20 years, we can provide good protection for your brake drums.
