Drum gear coupling repair

Drum gear coupling maintenance is generally carried out in the following ways:

First, check the coupling tooth surface meshing, the contact area along the tooth height is not less than 50%, along the tooth width is not less than 70%, the tooth surface can not have severe corrosion, wear and cracks.

2. Tighten the bolts evenly with a torque wrench.

3. The full circular runout of the outer gear ring of the coupling is not more than 0.03mm, and the end circular runout is not more than 0.02mm.

Fourth, if you need to remove the gear ring, use a tool, do not knock, so as not to bend or damage the shaft. When back installed, the gear ring should be heated to about 200 ° C and then installed on the shaft. The interference of the outer ring and the shaft is generally 0.01~0.03mm.

5, back to the indirect cylinder or other parts should be assembled according to the original mark and data.

Analyze the performance of the drum gear coupling under different conditions:

First, it has sufficient strength and service life.

Second, the structure is simple, installation and disassembly, easy maintenance.

Third, cushioning: for regular load starting or working load changes, the coupling needs to have cushioning and reducing elastic elements to protect the prime mover and the working machine from less or no damage.

Fourth, mobility: the mobility of the coupling refers to the ability to compensate the relative displacement of two rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all require portability. Movable performance compensation or additional load between shafts, bearings, couplings, and other components due to relative displacement between rotating members.
