Selection of Power Transmission Efficiency

The table of transmission performance in this catalog (P.1602) is based on the following conditions.
Q Application Coefficient Table
1) The chain drive mechanism is run in an atmosphere with a The power transmission efficiency table (P.1602) is based on minimum
temperature of -10˚C~+60˚C and with no abrasive particles.
2) There is no adverse impact on the mechanism, load variation. The transmitted kW shown in the table should be
such as corrosive gas or high humidity. corrected as follows depending on the actual magnitude of load variation.
3) The two shafts between which power is
transmitted are parallel with each other and Table 1. Application Coefficient Table

minimum load variation. Typical Mechanism Mechanism
Belt conveyor with small load
Smooth variation, Chain conveyor, ×1.0 ×1.2
Centrifugal pump, Centrifugal blower, ×1.0
Q Power Transmission Coefficient for Multiple Chains Transmission General textile machinery, General
On multiple roller chains, the load is not shared evenly between each chain row. Therefore, the machinery with small load variation.
power transmission efficiency of multiple roller chains cannot be obtained by simply multiplying Transmission Centrifugal compressor, Marine propeller,
the power transmission efficiency of a single chain by the number of chain rows. The power Conveyor with moderate load variation, Automatic
transmission efficiency of multiple roller chains should be obtained by multiplying the power with furnace, Drier, Pulverizer, General machine tools, ×1.3 ×1.2 ×1.4
