AGRICULTURAL MACHINE ROTARY WORKING MEMBER CREEPER GEAR Russian patent published in 2000 - IPC

FIELD: agricultural and transport engineering. SUBSTANCE: device has housing, input, intermediate and output shafts with fitted on spur gears one of which is installed on shaft for sliding and meshing with intermediate shaft gear. Input shaft has sliding three spur gear cluster designed for alternate engagement with two gears on intermediate shaft. Additional bevel is freely fitted on input shaft. Second additional bevel gear is fixed on intermediate shaft. Both gears are in constant meshing with similar bevel gears of output shaft. Internal tooth spur gear is built into bevel gear on input shaft for meshing with third gear of cluster. EFFECT: enlarged functional capabilities by increasing number of torque change steps and division of torque into flows. 2 cl, 4 dwg
