| Abstract: | Evaluation of the saw- chain cutting performance includes cutting resistance, sawing power, sawing efficiency and smooth operation of saw - chain, etc. Determination of these indicators depends on a reliable saw - chain cut- ting performance test device. Based on the LQ - 11 type saw - chain cutting performance test - bed, the designing experience was concluded and then the superior LQ - 18 type saw - chain cutting performance test - bed was designed with the help of modern computer and measurement technology. With the feed rate and stepless speed regulation of sprocket shaft rotating speed, the cutting forces in three directions, the driving torque, the rotating speed of the driving sprocket shaft and the feed rate were simultaneously measured directly, which was measured directly by the computer system. The testing bed can calculate and show the testing data as well as generate test report automatically with high accuracy and efficiency. This special saw-chain cutting test-bed was with the advantages of advanced structure, wide measurement range, high accuracy and excellent repetitiveness. |
