Good lubrication of drum gear coupling is the key

Drum gear coupling is one of the core products of our company, we from production to production, factory to do enough details. Each product will be delivered to the customer after the factory instructions, the following _ drum type coupling lubrication for you to introduce.

Introduction of three lubrication methods for drum gear coupling:

1, strong lubrication. The lubricating oil is injected into each small hole at the bottom of the gear teeth, and the oil enters the meshing surface under the action of centrifugal force, which plays the role of lubrication and cooling. The oil flows from both sides of the tooth after the meshing surface. This type of lubrication, the oil flow circulation is constant, the magazine will flow out, and the lubricating oil injected in the centrifugal force caused by the pressure into the tooth meshing surface, so it has a good lubrication cooling effect, suitable for high-speed heavy duty occasions.

2, oil storage lubrication. The lubricating oil is injected by the nozzle, and the lubricating oil is kept in the outer circle of the gear by centrifugal force during rotation. This lubrication mode will make the magazine residual and ring, and the heat dissipation effect of the oil flow is poor, so it is only suitable for the occasion of small power and low speed. There is also a non-flowing oil storage lubrication mode of this type, that is, the grease is poured into the inside and sealed, and washed and replaced regularly.

3, self-flow lubrication. The lubricating oil is shot into the nozzle, flows through the gear backlash, and flows out of the sleeve hole. This lubrication mode mainly plays a cooling role, and it is difficult to form an oil film. The tooth surface wear is faster than the following strong lubrication.

The 42Cr2Mo steel used by the drum gear coupling is _ high strength steel, with high strength and toughness, hardenability is also good, no obvious tempering brittleness, quenching deformation is small, tempering treatment after higher fatigue and resistance to multiple impacts, low temperature impact toughness is good, high temperature when creep strength and _ strength. Surface quenching after tempering is usually used as the heat treatment of the steel.

Wear resistance of drum gear coupling:

The internal structure of the drum gear coupling is very complex, the material used has the requirements of _, to meet the requirements of torque and speed! Generally speaking, the commonly used materials are 42crmo and 45 steel forgings. These two materials are mainly wear resistance, the higher the hardness of the material, the better the wear resistance, the greater the bearing torque, the longer the service life of the coupling!

To sum up:

Machinery manufacturers after years of research, after years of market baptism, we learn the advantages of the product itself, and then improve, product quality can improve a very large level, I plant coupling products and accessories popular domestic; These years many users are not without other options, but they still insist on cooperation with our factory, to give us strong support.
