What is the tolerance range of precision screws?
At present, with the continuous improvement of microwave plasma chemical vapor deposition technology, researchers hope to obtain more excellent products by increasing the microwave power. During the use of the three screws, it is necessary to continuously adjust the length of the pins extending into the rectangular waveguide to make the reflected power of the system reach the minimum value and improve the stability of the system. Since the length of the three screws extending into the waveguide needs to be continuously adjusted with the change of the input power, and the adjustment state of the three screws cannot be recorded after the adjustment is completed, repeated adjustment is still required in the subsequent work, resulting in a time-consuming adjustment process. long and low work efficiency. Especially under high power conditions, the traditional three-screw dispenser has a high risk of microwave leakage. When manually adjusting, the human body is exposed to microwaves for a long time, which has certain potential safety hazards.
At present, drum brakes are usually used for rear brakes of automobiles, and pump parts assemblies are widely used. The traditional assembly method is to use tools such as screwdrivers and retaining ring pliers for assembly. The disadvantage is that the assembly efficiency is low, the accuracy is average, and assembly quality problems are prone to occur, which affects the performance of the product assembly. Now take the brake wheel cylinder assembly with automatic clearance adjustment mechanism produced by our factory as an example to illustrate the installation of the elastic retaining ring
Advantages of anti-loose washers 1. Ensure that the clamping force of the connection is still maintained under strong vibration, which is better than fasteners that rely on friction to come from the lock; 2. Prevent the loosening of bolts caused by vibration, which no longer occurs due to fasteners related problems caused by loosening; 3. No special installation work is required, and it is easy to install and disassemble; 4. The temperature changes will not make the connector loose; 5. Durable; 6. Reusable.
Therefore, there is a need to design a bearing retaining ring disassembly and installation device that facilitates the installation and disassembly of the bearing retaining ring, and is safe and reliable.
