Description
Technical field
The utility model relates to a kind of oil pump field, and especially a kind of cleaning impurity is convenient, and structure is simple, easy to operate oil pump.
Background technique
Oil pump serves conclusive effect in the middle of whole engine lubrication, and it provides the machine oil of enough pressure and flow for whole motor, and to ensure that each friction member is lubricated fully, the pressure part that protection is relevant is not damaged.Oil pump generally includes the pump housing, gear assembly, driving shaft, pump cover, and the working principle of oil pump is: when the engine operates, the actuation gear on camshaft drives the driving gear of oil pump, and the driving gear be fixed on driving gear shaft is rotated, thus drive the reciprocal rotation of driven tooth crop rotation, machine oil is delivered to out oil pocket from oil suction chamber along backlash and pump wall.Like this, oil suction chamber place just forms low pressure and produces suction, the machine oil inspiration oil pocket in oil sump.Because driving and driven gear constantly rotates, machine oil is just constantly pressed to the position of needs.Because liquid medium constantly passes through from driving and driven gear, can cause the liquid residue of a part in driving and driven gear, when residual too much time can affect the normal use of oil pump greatly, residual liquid in usual cleaning machine oil pump is by cleaning solution implanter oil pump, again cleaning solution is poured out after cleaned, such setting not only cleans trouble, and residual liquid also clear up very not in time, greatly have impact on the use of user.
Model utility content
It is simple that problem to be solved in the utility model is to provide a kind of structure, and cleaning impurity is convenient, and structure is simple, easy to operate oil pump.
For solving the problems of the technologies described above, the utility model comprises the pump housing, pump cover, be located at liquid entering hole and the liquid outlet of pump housing both sides, cavity is provided with in the pump housing, gear assembly is provided with in cavity, driving shaft, gear assembly comprises inside and hollows out the driving gear of setting and be located in driving gear, and with the driven gear of axis hole, driving shaft inserts in the axis hole of this driven gear, for chute is arranged bottom the wall of described cavity chamber, described chute is tilted to extend to bottom by top, the top of described chute is near liquid entering hole place, the bottom of described chute is near liquid outlet place, described chute bottom end is provided with a tap hole, and the blocking device detachably arranged is coordinated with this tap hole.
After have employed said structure, owing to being that chute is arranged bottom air cavity wall, residual liquid residue in the cavities time, can because the Gravity Problem of liquid, automatic stream tap hole place, and tap hole is provided with a dismountable blocking device, facilitates user's banishing Liquid Residue.
As further improvement of the utility model, the bottom of chute extends straight down, and extend to the pump housing and outside air contacting point, described tap hole is located at this contacting point.
After have employed said structure, chute extends to the pump housing and air contact, greatly facilitates the use of user, and the blocking device on the oil pump pump housing only need be taken out by user, just can be flowed out by Liquid Residue smoothly.
As further improvement of the utility model, the blocking device of this oil pump is the jam-pack part of a top with convex cap, and the bottom of described jam-pack part is the slotting axle of a shape and length and this tap hole close-fitting, and described convex cap outer ring is provided with rubber seal.
After have employed said structure, arranging of convex cap can make user fill in more easily or take out jam-pack part, and inserts axle and tap hole close-fitting, and convex cap outer ring is provided with rubber seal, considerably increases the seal of the pump housing.
Accompanying drawing explanation
Figure 1 shows that the self-contained figure of this oil pump;
Embodiment
As shown in Figure 1, this oil pump comprises the pump housing (1), pump cover (2), be located at liquid entering hole (3) and the liquid outlet (4) of the pump housing (1) both sides, the pump housing is provided with cavity in (1), gear assembly is provided with in cavity, driving shaft (5), gear assembly comprises inside and hollows out the driving gear of setting and be located in driving gear, and with the driven gear of axis hole, driving shaft (5) inserts in the axis hole of this driven gear, for chute is arranged bottom the wall of described cavity chamber, described chute (9) is tilted to extend to bottom by top, the bottom of chute (9) extends straight down, extend to the pump housing and outside air contacting point, tap hole is located at this contacting point.Tap hole place is provided with blocking device, the blocking device of this oil pump is the jam-pack part of a top with convex cap (6), the bottom of jam-pack part is the slotting axle (8) of a shape and length and this tap hole close-fitting, and described convex cap outer ring is provided with rubber seal (7).
During use, owing to being that chute is arranged bottom air cavity wall, residual liquid residue in the cavities time, can because the Gravity Problem of liquid, automatic stream tap hole place, and tap hole is provided with a dismountable blocking device, facilitates user's banishing Liquid Residue.And arranging of convex cap can make user fill in more easily or take out jam-pack part, and insert axle and tap hole close-fitting, convex cap outer ring is provided with rubber seal, considerably increases the seal of the pump housing.Only blocking device need be taken out, just can carry out tapping operation to the residual liquid in this oil pump easily.
Claims (3)
1. an oil pump, comprise the pump housing, pump cover, be located at liquid entering hole and the liquid outlet of pump housing both sides, cavity is provided with in the pump housing, gear assembly is provided with in cavity, driving shaft, gear assembly comprises inside and hollows out the driving gear of setting and be located in driving gear, and with the driven gear of axis hole, driving shaft inserts in the axis hole of this driven gear, it is characterized in that: for chute is arranged bottom the wall of described cavity chamber, described chute is tilted to extend to bottom by top, the top of described chute is near liquid entering hole place, the bottom of described chute is near liquid outlet place, described chute bottom end is provided with a tap hole, and the blocking device detachably arranged is coordinated with this tap hole.
