Description
Technical field
The utility model is related to drive axle technical field, more particularly to a kind of new driving for engineering machinery
Bridge hub reduction gearbox.
Background technology
At present, China's construction machinery industry loading machine drive axle is an important component as chassis system, is used
In the weight of supporting loading machine, and the moment of torsion that drive axle input flange is inputted further increases and changes direction and passes to driving
Wheel, to meet driving wheel for the moment of torsion needed for overcoming resistance offer, while also there is differential action, to ensure wheel loader just
Often travel；Drive axle wheel edge slows down major part using the transmission of single-stage inside engaged gear, and driven gear is circular annular gear structure, and
For open wheel hem retarding mechanism；Lubrication uses grease lubrication, and lubricant effect is bad, and easily enters dust；Due to complete machine
It is required that gearratio it is big, the driven gear number of teeth is more, diameter big, and existence conditions can not realize carburizing quenching process manufacture, therefore quilt
Moving gear is cast using spheroidal graphite cast-iron, gear shapping machine Gear Shaping, the manufacture of the technique of flank of tooth impewdance matching；
Because ring gear low intensity itself and lubrication are bad；In the market occur ring gear abrasion and beat tooth phenomenon of the failure it is prominent
Go out；Simultaneously during each gear engagement transmission power, iron filings, the iron powder of generation can enter in lubricating oil, because existing drive axle is universal
It is not provided with lubrication oil filtration system, hence it is evident that reduce cleanliness of lubricating oil, causes gear, bearing, the oil sealing inside drive axle
Deng abrasion, the service life of drive axle is largely effected on.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of Novel drive axle wheel side for engineering machinery and subtracted
Fast case.The utility model specifically uses following technical scheme to achieve these goals：
A kind of Novel drive axle hub reduction gearbox for engineering machinery, including shell, described shell include lower house
And upper shell, lower house and upper shell constitute in closing space, shell and power transmission shaft A, power transmission shaft B and power transmission shaft C be arranged side by side,
Power transmission shaft A is input shaft, and power transmission shaft A extends one end shell, and power transmission shaft C is output shaft, and power transmission shaft C extends shell in one end,
Input gear is provided with power transmission shaft A, power transmission shaft B is disposed with primary transmission gear and secondary transmission gear from top to bottom,
Output gear is provided with power transmission shaft C, input gear coordinates with primary transmission gear, and secondary transmission gear is matched somebody with somebody with output gear
Close.
Further, power transmission shaft A, power transmission shaft B and power transmission shaft C are fixed on shell by bearing.
Input gear, output gear primary transmission gear and secondary transmission gear, gear is using at carburizing steel carburizing and quenching
Reason, improves the strength of gear teeth.
Further, it is filled with lubricating oil in closing space.
Further, opened up on the shell and magnet and long bolt are provided with a window, window, magnet passes through plain washer
The lower end of long bolt is fixed on nut, long bolt upper end is locked on shell by bolt and spring washer.
Further, power transmission shaft B primary transmissions gear and secondary transmission gear are integrally formed.
Further, power transmission shaft A and input gear are integrally formed, and power transmission shaft C and output gear are integrally formed.
The beneficial effects of the utility model are as follows：
Compared with prior art, the features such as the utility model has reasonable in design, simple in construction, easy to process, it is ensured that total
Gearratio with it is original consistent；Gear is handled using carburizing steel carburizing and quenching, improves the strength of gear teeth；Lubrication uses oil lubrication, carries
High lubricant effect, reduces tooth surface abrasion, extends service life；Magnet collects each gear of reduction box in joggleword process
Iron filings, the iron powder of middle generation, are effectively ensured reduction box cleanliness of lubricating oil, substantially increase the use longevity of drive axle
Life, reduces reduction box after-sales service expense, increases enterprise income.
