Analysis of the failure condition of the spring passive disk Self-Diagnosis Mask Machine,Disposable Mask Packing Machine,Data Printer Packaging Machine,Packaging Machine With Bagging Device Wuxi Kanghe Medical Consulting Co., Ltd. , https://www.jskanghe.com
The spring passive disk fault condition is mainly manifested in the fact that the automatic shifting cannot be achieved according to the pressure of the pressure spring (that is, the so-called jamming).
The possible reasons are as follows:
1. One-way rotation (food, packaging, woodworking, electronic cables, band saw machinery, etc.)
1. When the product is installed, the shaft hole of the shaft and the shifting disc that needs to be installed is too poor to be installed smoothly. According to the national standard: the diameter tolerance of the shaft should be -0.021. â– Solution: Replace (but this is not covered by the warranty, it is caused by the implementation of the product installation unit.)
2. During the use of the shifting disc, it is not required to follow the precautions attached to the product to periodically shift the whole time and use it for a long time in a certain part, resulting in the shifting disc umbrella and the umbrella wheel, the umbrella wheel and the shaft center. The two ends are partially rusted and cannot be changed.
â– Solution: Disassemble the product, remove the rust, infuse the grease, and reassemble.
2. Positive and negative rotation conditions (mainly printing and dyeing machinery, sometimes used in food mixing machinery, not common.)
1. (The same one-way rotation condition as above. 1.)
2. (The same one-way rotation condition as above. 2.)
3. The materials selected for the product cannot be used for the normal use of such machines (based on existing information, such machines should be made of cast iron with a hardness of not less than 180 Brinell hardness). The fixed round shaft and the flat round steel key of the fixed and moving umbrella wheel will be fixed, and the key groove of the moving umbrella wheel will be enlarged, and the shifting cannot be performed.
â– Solution: Replace.
4. Because the machine is used for forward and reverse rotation, at the moment of positive transformation reversal or reverse transformation forward rotation, the belt will instantaneously rub with the umbrella wheel, generating a large amount of heat, causing the grease in the shifting disc to be filled at the factory. The flowability is increased and the gap between the components of the product is lost, and the contact surface between the components is rusted (so the mechanical environment is very humid, and the metal product is easily rusted). Can't change speed.
â– Solution: Disassemble the product, remove the rust, infuse the grease, and reassemble. (but need to exclude 3. status)
