摘要:

介绍了用于测定油锯锯切效率的一种新型试验方法和专用锯切试验机,并用该专用锯切试验机对德国STIHL锯链、美国OREGON锯链及国产JL10型锯链的锯切效率进行测定。该专用试验机采用恒进锯力进锯方式,且锯口面积的取值与锯切时间的测量保持了良好的一致性,从而提高了锯切效率的计算精度。该专用锯切试验机结构紧凑、进锯机构摩擦阻力小,测定精度高,重复性好,适用范围广。采用这种试验机测定不同锯链的锯切效率,可比性强。

Abstract:

The paper presented a new testing method and a special testing device for measuring cutting-rate of saw-chains. The cutting-rates of German STIHL saw-chain, American OREGON saw-chain and domestic JL10 saw-chain were measured through operating the device. The force in the vertical forward movement orientation was kept equal when a chain saw was operated in the device. It kept a good coherency between the cutting area determining and the cutting time measuring. So it can improve the measuring precision of cutting-rate of saw-chains. The special testing device was noted for compact structure and small friction resistance to vertical forward movement with a high measuring precision, a good repetitiveness and a wide applicable range. So a good contrast could be obtained in measuring the cutting-rate of saw-chains through the special testing device.
