Description
Technical field
The present invention relates to a kind of sanitation truck gear pump.
Background technology
The gear pump filled on sanitation cart is the power set of vehicle, and the rotation motor that main driving cleans road surface is used, but
It is if when sanitation cart startup need not be cleaned, must just stop motor.Motor stops to require that gear pump also stops.Tooth
Wheel pump is driven by engine belt pulley, as long as engine rotation gear pump is with regard to concomitant rotation.Multiplexing is crossed which results in gear pump
Make, cause to damage.
The content of the invention
The present invention provides rational in infrastructure, simple to operate, service life to solve technical problem present in known technology
A kind of sanitation truck gear pump of factory.
The present invention is adopted the technical scheme that to solve technical problem present in known technology：A kind of sanitation truck tooth
Driving shaft is equipped with the middle part of wheel pump, including protecgulum, intermediate and bonnet, protecgulum, driving shaft front end is provided with locking nut, middle part
It is provided between protecgulum in high-speed oil seal, driving shaft middle part, intermediate and driving gear is installed and in the middle part of driving shaft with
Mesosome joint place, which is provided with below bushing, driving gear, is provided with the driven gear engaged, is provided with the middle part of driven gear
Driven shaft, from protecgulum, overhang is 79mm to driving shaft to the left, and protecgulum, intermediate and bonnet be affixed by screw, the protecgulum, in
Mesosome and bonnet joint place are provided with multiple sealing gaskets.
Advantages and positive effects of the present invention are：The invention provides a kind of sanitation truck rational in infrastructure, simple operation
Gear pump.The length of protecgulum is stretched out by lengthening driving shaft, to add clutch on driving shaft, and by driving shaft spindle nose before
End sets retaining mechanism to be used for fixed clutch, so as to realize that sanitation cart realizes that gear pump stops and work during sweeping the floor
Make.Because merely add the overhang of driving shaft so that the present invention had not only saved space but also economy and durability.
