MB stepless transmission needs to choose different structural forms according to different working environments

Source: rubyrad.com Release time: 2014-07-10

MB stepless speed changer is a common power transmission mechanism. Because of its advantages of continuous speed change, it is used in various mechanical transmission systems. MB stepless transmission has certain choices and requirements for the working environment. For different working environments, it is necessary to choose MB stepless transmissions with different structural forms. The structure of MB stepless speed changer is open type, protection type, closed type and explosion-proof type. Let's take a look at the choice of MB stepless speed changer for different working environments:
1. Open
This MB stepless transmission is cheap and has the best heat dissipation conditions, but because the rotor and windings are exposed to the air, it is easy to be eroded by water vapor, dust, iron filings, oil, etc., which affects the normal operation and service life of the stepless transmission. Therefore, it can only be used in a dry, dust-free, non-corrosive and explosive gas working environment.
2. Explosion-proof
Explosion-proof MB stepless speed changer is made of explosion-proof type, increased safety type and positive pressure type on the basis of sealed structure. It is suitable for working environments with explosion danger, such as mines, oil depots, gas stations and other places. In addition, for humid and hot areas, high altitude areas and stepless speed changers for ships, stepless speed changers with special protection requirements should also be selected.
3. Protective
This MB stepless speed changer can generally prevent outside debris such as water droplets and iron filings from falling into the stepless speed changer, but it cannot prevent the intrusion of moisture and dust. Only suitable for dry, dust-free, non-corrosive and explosive gas working environment. The ventilation and heat dissipation conditions of this continuously variable transmission are also good.
4. Closed
There are three types of MB continuously variable transmissions: self-cooling, forced ventilation and closed. The first type is generally equipped with a fan. The first two types of stepless speed changers can prevent water droplets or debris in any direction from entering the stepless speed changer. Moist air and dust are not easy to invade. The harshest working environment with corrosive gas is the most common application. The closed continuously variable transmission is suitable for production machinery immersed in liquid, such as double suction pumps.
The above are the different applicable environments of MB stepless transmissions with different structures. In the future, when you use MB stepless transmissions, you must pay special attention to this to ensure that the MB stepless transmission is damaged for a long time.
