CIRCULAR SAW Russian patent published in 1998 - IPC

FIELD: wood-working equipment, may be used in any machine requiring adaptive self-regulation of cutting and feeding speed. SUBSTANCE: circular saw has base, balancing frame with sawing shaft and electric engine. Output end of electric engine is connected with sawing shaft through transmission and with satellite gear of moving up planetary mechanism through centrifugal clutch. Housing of this mechanism is rigidly fixed on balancing frame. Output shafts of internal central gear and external central gear are provided with control brakes. Such construction of self-regulation mechanism of machine allows consumed power to be reduced and output to be increased by 1.3 times. This circular saw may be used in machines of different types where feeding motion is performed by main motion drive. EFFECT: increased efficiency, reduced power consumption and enhanced reliability in operation. 2 dwg
