Description
Technical field
The utility model relates to technical field of mechanical equipment, particularly relates to a kind of gear pump of internal messing.
Background technique
Gear pump is a kind of rotor pump by gear fed sheet of a media, and it is made up of the gear of pair of meshing usually, comprises driving gear and driven gear, and driving gear drives driven gear to rotate with fed sheet of a media.Gear pump structure is simple, and easy to process, volume is little, and quality is light, be widely used, but the flow of gear pump is unadjustable, poor work stability, has used inconvenience to the characteristic such as insensitive polluted.
The vigorously strong development of China's economy, supply falls short of demand to make the domestic demand to gear pump, so found, a kind of structure is simple, suction capacity is strong, functional reliability is high, the gear pump of the internal messing of applied range, has great importance.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of gear pump of internal messing, makes that its structure is simple, suction capacity is strong, functional reliability is high, working efficiency is high, applied range.
For solving the problem, the utility model provides a kind of gear pump of internal messing, comprise the pump housing, main shaft, driving gear, driven tooth wheels, protecgulum, bonnet and mechanical seal, the pump housing is arranged on main shaft, the pump housing is provided with deep groove ball bearing one, pump housing rear end is provided with bonnet, deep groove ball bearing two is arranged on bonnet, the front end of main shaft is provided with driving gear, driving gear and driven tooth wheels are connected with a joggle, bearing pin is arranged on the center hole of driven tooth wheels, and the front end of the pump housing is provided with protecgulum, and on main shaft, also cover has mechanical seal.
Further, A nibs circlip is provided with between described deep groove ball bearing one and the pump housing.
Further, described bonnet and the pump housing are threaded connection, and are fixed by interior hexagonal flush end Cock screw.
Further, the gear of described driving gear and driven tooth wheels is circular tooth gear.
After adopting such design, the utility model at least has the following advantages:
Gear pump of the present utility model has superior mechanical property, and structure is simple, and easy to process, have good self-priming performance, good seal performance, reliable operation degree is high.
During operation, stationarity is good, engagement rotation between gear, and internal gear adopts normal shift, and the strong interference avoiding involute and radial interference, transmission is effective, and working efficiency is high.
Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solutions of the utility model, and in order to better understand technological means of the present utility model, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
