Problems solved by technology

[0003] The planetary gear reducer installed in the turbo fracturing equipment often adopts a cantilever integral structure due to the small space, but if the support of the planetary frame is not handled properly, the rigidity of the planetary frame may be reduced, the vibration may be increased, and the unevenness of the gear meshing parts may be caused. Phenomenon strengthened, thereby greatly reducing the reliability and life of the planetary gear drive

Embodiment Construction

[0025] Such as Figures 1 to 6 As shown, a reduction box for turbo fracturing, the reduction box includes a sun gear shaft 2, a planetary wheel 11 and a bearing 13, the number of the planetary wheel 11 is 3, the number of the bearing 13 is 6, and the number of bearings 13 is two by two The set is used to fix a planetary gear 11, and 6 bearings 13 and 3 planetary gears 11 are respectively socketed to form 3 sets of planetary gear sets. The sun gear shaft 2 includes a large end gear and a small end gear. The 3 sets of planetary gear sets are The big end gear is distributed around it as the center of a circle, and the planetary gear 11 is meshedly connected with the big end gear. The three sets of planetary gear sets are evenly distributed around the big end gear as the center of circle. The transmission ratio of the reduction box is large, and the power is input by the small end gear of the sun gear shaft, through the engagement of the large end gear of the sun gear shaft and t...

Abstract

The invention discloses a speed reduction box for turbine fracturing. The speed reduction box is compact in overall structure, small in volume, light in weight and large in transmission ratio, power is input through a sun wheel shaft small-end gear, speed reducing and torque increasing are performed through engaging between sun wheel shaft large-end gears and planet wheels, the power is output through planet carriers, the gear size and quantity are reduced utilizing the structure of a planet wheel set, the speed reduction box for the turbine fracturing is more suitable for the turbine engine speed reduction requirements, the effect of convenient maintenance can be achieved by opening a cover plate through an observation hole, by means of coordination use of a brake device and a brake pad,equipment can be made to stop running immediately in case of emergency, the equipment and personal safety is protected.

Description

technical field [0001] The invention relates to the technical field of turbo fracturing, in particular to a reduction box for turbo fracturing. Background technique [0002] The current vehicle-mounted turbo fracturing equipment is powered by a turbine engine, the transmission device is a reduction box and a transmission shaft or a coupling, and the actuator is a fracturing plunger pump. The turbine engine itself has the advantages of small size, light weight, and high power density. With the same size and weight, the unit power of the turbine fracturing equipment is more than twice that of conventional diesel engine fracturing equipment. Turbine engines can directly use 100% natural gas as fuel, unlike electric-driven fracturing equipment, which does not require intermediate links for gas-fired power generation, which saves the investment cost of gas-fired generator sets. The risk of machine failure is evenly distributed to each turbine fracturing equipment, avoiding the r...
