Discussion on MLL Brake Wheel Plum Blossom Elastic Coupling

Introduce:
The plum blossom coupling is a more common type of coupling, and the MLL brake wheel plum blossom elastic coupling is more commonly used by people, so many people choose this coupling. It has a simple structure, The number of parts is small, the radial dimension is relatively small, no lubrication is required, and the elastic element has a high pressure bearing capacity. In addition to the double-flange plum-shaped elastic coupling, when we replace the plum-shaped elastic parts of the vulnerable parts, we need to move the half-coupling axially, otherwise the replacement will fail, and the position will cause deviation. Although the coupling is a small object, it has a big function.

Precautions for MLL type brake wheel plum blossom elastic coupling:
The end face processing of the MLL brake wheel plum blossom elastic coupling is often carried out on the shaft. This is to make the tenon on the end face of the coupling accurately concentric with the center line of the shaft. Note_The end face of the coupling is perpendicular to the rotor shaft, and attention should be paid to whether the mutual cooperation of the centering tenons meets the requirements. For flanged couplings without centering tenons, the two coupling halves should be fitted together for reaming after drilling.
(1) Gear-type safety inspection: It needs to be dismantled and inspected when the transmission noise increases or the product is overhauled.
(2) The basic requirements for its inspection: its connection should be firm, the connecting bolts and connecting keys should not be loose, and the radial and end surface jumps in the transmission should not be obvious when visually inspected , when checking with a meter, it cannot be greater than a larger number. (3) There are problems such as the seal of the lubricating series oil is not intact, the oil deteriorates, and the oil seeps and runs away. When the above situation occurs, the seal and the oil need to be replaced, and the oil needs to be replenished as soon as possible when it is lacking.
(4) Inspection of the coupling: when the rubber ring and the leather pad are damaged, they need to be replaced as soon as possible. Drill the hole once and replace the standard new pin. The original hole cannot be enlarged to match the new pin.

Summarize:
The heat treatment of MLL brake wheel plum blossom elastic coupling is divided into preparatory heat treatment and final heat treatment. In modern industrial production, the heat treatment of coupling has become an important technical regulation. This is due to the improved hardness, strength, elasticity and wear resistance of iron and steel and certain alloys with excellent mechanical properties. In addition to obtaining the required chemical composition during smelting, it must be obtained after heat treatment. Therefore, in order to achieve technical First of all, in the process of producing the coupling, we need to heat treat the coupling.
