Technical field
The utility model relates to oil pump technology field, particularly relates to a kind of vertical gear oil pump.
Background technique
The working principle of gear oil pump is, form closed active chamber at the flank of tooth of pump case, end cap and driving gear, driven gear, driving gear and driven gear constantly rotate, and the gear teeth then intermesh for a pair for a pair, fluid just constantly sucks from import, extrudes from outlet.When load one timing, the output of oil pressure and oil mass is also certain, and as changed oil pressure and oil mass, change power rotating speed or install overflow mechanism on gear pump output pipe, this method needs increasing device volume, increases equipment investment.
Model utility content
For the problems referred to above, the utility model provides a kind of simple and compact for structure, volume is little, easy and simple to handle, cost of production is low vertical gear oil pump.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of vertical gear oil pump, comprise the pump housing, pump cover, driving shaft, driven shaft, be set in driving shaft respectively, driving gear on driven shaft and driven gear, described driving gear and driven gear are meshed, hydraulic adjustment device is provided with in described pump cover, described hydraulic adjustment device is by adjusting screw rod, set screw nut, gland nut, check ring, spring and steel ball composition, described gland nut is fixed on pump cover side, described adjusting screw rod runs through gland nut, and fixed by set screw nut, described check ring and spring housing are located at adjusting screw rod, spring one end is against on check ring, the other end is connected with steel ball, described steel ball props up oil duct.
Further, described pump cover is fixedly connected with the pump housing by stud bolt, and is provided with locating stud, is provided with pad between pump cover and the pump housing, makes pump cover and gear face distance within the scope of 0.02-0.06mm, prevents gear from encountering pump cover and produces noise and wearing and tearing.
Further, described driving shaft stretches out the pump housing and connects belt pulley, and driving shaft stretches out pump housing place and pushes down filler by Gland and seal, and prevents dust from entering in the pump housing, causes gear stuck phenomenon, improves working life.
Further, described driving shaft and driving gear, be equipped with lining between driven shaft and driven gear.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
The utility model is provided with hydraulic adjustment device, adjusts spring pressure by adjusting screw rod, thus realizes oil mass and the oil pressure of adjusting gear oil pump, simple and compact for structure, volume is little, easy and simple to handle, cost of production is low.
