Wheel, transmission gear and output bearing, the output bearing are equipped with output sleeve, and the output sleeve is equipped with output gear,
The both ends of the countershaft are equipped with bearing, duplicate gear and gear are equipped on the countershaft, and gear is engaged with input gear
It connects, shift fork is fixed on the countershaft, the top of the shift fork is fixed with pull rod, and the pull rod is arranged far from one end of shift fork
In the outside of cabinet, the pull rod is equipped with shift block far from one end of cabinet, and the top of shift block is equipped with circular hole, the circular hole
In be inserted with shift handle, the top of the cabinet is equipped with fixed bracket, and the fixed bracket is equipped with link block, the connection
The side of block is equipped with connecting rod, and the connecting rod is equipped with shaft, and shift handle passes through the middle part of shaft.
Preferably, the cabinet is equipped with case lid, and oil sealing is equipped between cabinet and case lid.
Preferably, the duplicate gear is the gear set that a gear wheel and a pinion gear are combined, and canine tooth
Wheel is an integral molding structure with pinion gear.
Preferably, the bottom of the shift fork is equipped with circular arc shaped opening, and top is equipped with circular open.
Preferably, the shaft is equipped with fastening screw.
The present invention uses second gear gear, and the transmission velocity ratio of gear can be shifted gears by shift handle, structure novel, design
Rationally, the present invention is mounted in small sized high-pressure water pump Fire Fighting Pumps, and it is lower in needs to solve small sized high-pressure water pump Fire Fighting Pumps
Due revolving speed is not achieved when supplying water in pressure big flow, and is difficult to provide enough torsions when requiring maximum pressure to supply water
Square guarantees the problem of stable operation, can export enough torques, can work in multiple job sites, improves being applicable in for pump group
Performance.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-3, a kind of two grades of gearboxes of high-pressure pump, including cabinet 1, cabinet 1 is interior to be equipped with input axle sleeve 9 and countershaft 7,
And input axle sleeve 9 is arranged in parallel with countershaft 7, one end of input axle sleeve 9 is equipped with input shaft bearing 8, successively installs in input axle sleeve 9
There are input gear 10, transmission gear 11 and output bearing 12, output bearing 12 is equipped with output sleeve 13, sets on output sleeve 13
Have output gear 14, the both ends of countershaft 7 are equipped with bearing 6, duplicate gear 5 and gear 17 be installed on countershaft 7, and gear 17 with
