Abstract
The utility model belongs to the technical field of pumps, and specifically relates to a gear oil pump. The gear oil pump comprises a pump shell and end covers for sealing the two ends of the pump shell, wherein one side of the pump shell is provided with an inlet, the other side of the pump shell is provided with an outlet, and the pump shell is internally provided with a driving gear and a driven gear which is positioned below the driving gear and is meshed with the driving gear; the driving gear and the driven gear are arranged in the pump shell respectively through a shaft, and one end of the shaft, provided with the driving gear, passes through one end cover so as to extend out of the pump shell; and the pump shell is provided with an observing port for observing a meshing condition of the driving gear and the driven gear, and a cover plate which is assembled on the observing port so as to cover the observing port. When the meshing condition of the driving gear and the driven gear in the pump shell and a wear condition are checked, observation can be available only by taking the cover plate out of the observing port without need of disassembling the end covers, so that the workload of a maintainer is reduced, and the service efficiency of the pump is improved.
Description
Technical field
The utility model belongs to the pump technical field, is specifically related to a kind of gear oil pump.
Background technique
Gear oil pump mainly is comprised of parts such as intermeshing driving gear, driven gear, pump case, end cap 4 and transmission shafts.The working principle of gear oil pump is, the flank of tooth of pump case, end cap and driving gear, driven gear forms the active chamber of sealing, and driving gear and driven gear constantly rotate, and the gear teeth are a pair of follows a pair of intermeshing, fluid just constantly sucks from import, extrudes from outlet.Pump is after working long hours, produce certain wearing and tearing owing to rub between driving gear, the driven gear, affect the working efficiency of oil pump, and existing pump structure need to disassemble end cap when overhauling, and observes maintenance, again end cap is installed after having overhauled, and can not directly outside pump case, observe maintenance to inside, and increased the workload of maintenance, affect the utilization efficiency of pump.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of gear oil pump, and it has for the observation panel of observing in the pump case, need not when maintenance end cap to be disassembled, and reduces maintainer's workload, improves the utilization efficiency of pump.
The realization the technical solution of the utility model is as follows:
A kind of gear oil pump, comprise pump case, and the end cap that the pump case two ends are sealed, one side of pump case has import, opposite side has outlet, be provided with driving gear in the described pump case, and be positioned at the driven gear of driving gear below and driving gear engagement, described driving gear, driven gear is arranged in the pump case by an axle respectively, axle one end of described installation driving gear passes an end cap and reaches the pump case outside, offer on the described pump case for the observation panel of observing driving gear and driven gear engagement situation, and be assemblied in the cover plate that in this observation panel observation panel is carried out capping.
Described cover plate is the cover plate that transparent material is made, and when pump was overhauled, the cover plate that need not to be assemblied in the observation panel took off like this, directly gets final product by observing transparent cover plate.
Described end cap and pump case are fixed together by screw.
Adopted such scheme, in the engagement situation to the driving gear in the pump case, driven gear, and abrasion condition is when checking, cover plate can be taken out in the observation panel and just can observe, need not end cap is disassembled, reduce maintainer's workload, improve the utilization efficiency of pump.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Among the figure, 1 is pump case, and 2 is end cap, and 3 are import, and 4 are outlet, and 5 is axle, and 6 is observation panel, and 7 is cover plate, and 8 is coupling, and 9 is motor, and 10 is base.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Referring to Fig. 1,2, a kind of gear oil pump, comprise pump case 1, and the end cap 2 that the pump case two ends are sealed, one side of pump case has import 3, opposite side has outlet 4, be provided with driving gear in the pump case, and be positioned at the driven gear of driving gear below and driving gear engagement, driving gear, driven gear is arranged in the pump case by an axle respectively, axle 5 one ends that driving gear is installed pass an end cap and reach the pump case outside, offer on the pump case for the observation panel 6 of observing driving gear and driven gear engagement situation, and be assemblied in the cover plate 7 that in this observation panel observation panel is carried out capping.Cover plate is the cover plate that transparent material is made.End cap and pump case are fixed together by screw.Driving gear shaft 5 is installed is connected with the output shaft of motor 9 by coupling 8, thereby motor can drive driving gear and driven gear rotation by shaft coupling, realizes the function of oil pump.Pump case and motor are installed on the same base 10, are convenient to carrying, use.
Claims (3)
1. gear oil pump, comprise pump case, and the end cap that the pump case two ends are sealed, one side of pump case has import, opposite side has outlet, be provided with driving gear in the described pump case, and be positioned at the driven gear of driving gear below and driving gear engagement, described driving gear, driven gear is arranged in the pump case by an axle respectively, axle one end of described installation driving gear passes an end cap and reaches the pump case outside, it is characterized in that: offer on the described pump case for the observation panel of observing driving gear and driven gear engagement situation, and be assemblied in the cover plate that in this observation panel observation panel is carried out capping.
