摘要： The present invention discloses a reduction gearbox for turbine fracturing with a compact overall structure, a small volume, a light weight and a large transmission ratio, wherein the power is input through a small end gear of the sun wheel axle, slowdown and increased the torque through the engagement between the big end gear of the sun wheel axle and the planetary gear, and output through the planetary carrier. A structure of the planetary gear set with reduced gear size and number is more suitable for the reduction requirement of a turbine engine. It can be observed through an observation hole by opening the cover plate, which is convenient for maintenance. A brake apparatus works with a brake pad so as to promptly stop the equipment in case of emergency to ensure the equipment and personal safety.
