Speed reducer special for firefighting boosting high-torque kinetic energy

Abstract

The invention relates to a speed reducer special for firefighting boosting high-torque kinetic energy. The speed reducer comprises a machine shell. The machine shell comprises an upper box body and alower box body which are spliced with each other in a sealing mode. Cavities are formed in the upper box body and the lower box body. The upper box body is provided with a hollow input shaft, and oneend of the hollow input shaft penetrates out of the upper box body. The hollow input shaft and a gear shaft arranged inside the upper box body are connected in a sleeving mode and further rotate coaxially. An output shaft is arranged inside the upper box body, and one end of the output shaft penetrates out of the lower box body. The output shaft is sleeved with a driven gear and further provided with the driven shaft in a coaxial rotating mode. The driven gear and the gear shaft are engaged to rotate. Engine oil is contained in the cavities. The upper box body is provided with an engine oil circulation cooling device. Through the arrangement, the external diameter of the hollow shaft is large, the outer the place is, the larger the acting force for transmitting effective moment of force is, and therefore the torque transmission efficiency is improved through the hollow shaft, and the gear shaft can achieve higher rotation torque. The engine oil can be cooled through the engine oil circulation cooling device, and hence the service life of the driven gear and the service life of the gear shaft are prolonged.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a special reducer for fire boosting, high torsion and strong kinetic energy. Background technique [0002] At present, on fire trucks, the reducer is a bridge connecting the engine and the supercharged high-pressure water pump. The liquid is pumped out through the high-pressure water pump to extinguish the fire, which requires a high torque. If the engine is directly connected to the supercharged high-pressure water pump, it will cause the engine Insufficient torque makes the water pressure too small and the high-pressure water pump causes heat problems due to excessive speed. [0003] The existing reducer transmits a large torque during use, and the gears generate a lot of heat during the meshing transmission process, which accelerates the wear of the gears and reduces the service life of the reducer, so there is room for improvement.
