    Belt and direct comparison:

    • The work efficiency Good gear transmission efficiency can reach 98% 99% excellent belt transmission design under normal working conditions also can achieve 99% efficiency.(the difference does not depend on the choice of the ways of transmission, and depending on the manufacturer's design and manufacturing level)
    • No-load power consumption no-load pressure usually remain above 2.5 bar, some even up to 4 bar, to ensure that the lubrication of gear box For belt transmission mode, in theory, no-load pressure can be zero, because the rotor inlet enough oil to lubricate the rotor and bearing.Usually for safety, pressure to maintain at about 0.5 bar.
    • Loss of oil oil under the condition of gear box is the first victim For belt transmission system, the loss of oil condition has no effect on it.
    • According to user requirements design change work pressure Gear transmission need to change the original design, to replace the assembly to the whole transmission system, virtually increase the new cost.For belt transmission design manufacturers simply change the diameter of the pulley, and working pressure can be designed in accordance with user requirements completely, so that can meet with the same power of the motor is more air volume.
    • Users of installed air compressor pressure change For gear transmission of air compressor, this work is very difficult and expensive.To simply replace the pulley belt drive type air compressor.
    • Install new bearing When rotor bearing need to change, for air compressor gear, gear box and the gearbox spindle bearing needs to overhaul at the same time, the cost is far more than the belt transmission.For belt drive air compressor, there is no such problem.
    • Replace the shaft seal (common parts, screw machine need regular replacement) for gear drive type air compressor, must first separate motor, even the axis, to close to the shaft seal, make this time-consuming work, so as to increase maintenance costs.For belt transmission type air compressor, only need to unload first pulley can, is very convenient.
    • Motor or rotor bearing damage For gear drive air compressor, when the motor or rotor bearing damage, often hurt important parts caused by direct and indirect double damage.Belt drive air compressor does not exist the condition
    • Structure noise due to the motor gear drive air compressor and rotor rigid connection, the vibration of the rotor of the compression chamber is passed to the gear box and the motor bearing, which not only increase the motor bearing wear, increase the machine noise at the same time.

    Belt drive structure is simple and obvious advantages.



    1. First check whether the power switch, the power cord before starting without damage, the power cord and ground wire connection is reliable, otherwise ask electrician to repair immediately
    2. Check before starting the compressor foundation is stable, if air tank in the water and oil pollution emissions clean, otherwise ask electrician to repair immediately
    3. First before starting the check the piston cylinder, crank case, pulley screw fastening, air filter are no foreign bodies blocked and damaged, piston cylinder tube without damage, otherwise ask electrician to repair immediately
    4. First check whether the oil level before starting the oil around two-thirds of the mirror, otherwise please as soon as possible, come on, if the lubricating oil is dirty or spill, ask electrician to repair immediately
    5. First to check the elastic belt before starting the moderate and no rupture, motor all fastening screws are normal, pulley, the motor rotation is flexible, whether the belt cover tighten without damage, otherwise ask electrician to repair immediately
    6. After startup check whether the transmission shaft is ringing, the trachea and joint is no leakage, pressure is stable in 0.4-0.8 Mpa, oil-water filter drainage is normal, otherwise ask electrician to repair immediately
