Abstract
The utility model relates to improvement of a small-diameter gear transmission mechanism of a gear pump. The improved small-diameter gear transmission mechanism comprises an input shaft, a driving gear and a driven gear which is engaged with the driving gear, and is characterized in that: a mounting groove is arranged on the center of the driving gear, a sliding block which is provided with a mounting hole is installed inside the mounting groove, and the input shaft for driving the driving gear is installed inside the mounting hole of the sliding block in a penetrating manner. The small-diameter gear transmission mechanism has the advantages that: the harmful movable load which is produced on the input end can be balanced when the gear pump runs at a high speed, the stress situation of a driving gear component can be improved, the mechanical vibration can be reduced, and the service life of the gear pump can be prolonged; and moreover, the unequal-load phenomenon occurred when the driving gear is simultaneously engaged with two driven gears can also be balanced, so the engagement movement stress of the gears can be more uniform, the pressure fluctuation caused by the imbalanced stress can be improved, and the transmission torque of the gear can be improved.
Description
Technical field
The utility model gear pump is made the field, and the small diameter gear driving mechanism that particularly relates to a kind of gear pump improves.
Background technique
Gear pump is simple in structure owing to it, good reliability is widely used in the hydraulic system.Gear pump as shown in Figure 6 has two filler openings and two oil outlets, and its purposes is to provide pressure lubrication for booster engine gear and bearing.Driving gear among Fig. 6 and transmission shaft are monolithic construction, have following deficiency in actual use: 1, in transmission owing to made and the influence of assembly precision, in the rotation of reality, can produce extra dynamic load, higher because of the rotating speed of gear pump again, this certainly will strengthen dynamic load numerical value, causes the gear pump premature damage.2, because driving gear supports by transmission shaft, when be stressed fluctuation or gear accuracy of manufacturing influenced, the amount of floating of driving gear was minimum, causes the load unbalanced phenomena easily, has shortened the working life of gear pump.3, influenced by gear diameter, the gearing shaft restricted diameter causes the shaft drive ability less.4, gear pump mechanical vibration meeting when work produces certain noise, and is unfavorable for the stability of hydraulic pressure output.
Summary of the invention
The utility model provides a kind of small diameter gear driving mechanism simple in structure, that can prolong gear pump working life and can improve the gear pump of transmitting torque to improve for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the small diameter gear driving mechanism of gear pump improves, comprise input shaft, driving gear and with the driven gear of its engagement, it is characterized in that: described driving gear center is shaped on mounting groove, the slide blocks that has mounting hole on it is housed in described mounting groove, is coated with the input shaft that drives driving gear in the mounting hole of described slide blocks.
The utility model can also adopt following technological scheme:
The mounting groove of described driving gear center is a spline.
The shape of described slide blocks and the spline of driving gear are complementary.
Mounting hole on the described slide blocks is the oblong aperture that has arc section.
Advantage and the good effect that the utlity model has are: because the utility model adopts the drive mechanism that floats, promptly utilize the useful space of gear tooth that the translation freedoms that special type spline is realized X, Y direction is installed, guaranteed that so not only gear pump is when running up, can effectively offset the harmful dynamic load that produces from input end, thereby improve the stressing conditions of driving gear assembly, reduce mechanical vibration, prolong gear pump working life; But also can the balanced driving gear while carry phenomenon with the inequality in two driven gear gear motions, thus make the gear engagement motion stressed evenly, improve owing to the pressure surge that unbalance stress brought the transmitting torque of raising gear.

Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 5, the small diameter gear driving mechanism of gear pump improves, comprise input shaft 3, driving gear 1 and with the driven gear 4 of its engagement.The center of described driving gear 1 is shaped on mounting groove, and in the present embodiment, the mounting groove of described driving gear center is a spline.Drive fit is equipped with the slide blocks 2 that has mounting hole 2-1 on it in the described mounting groove, and in the present embodiment, the shape of described slide blocks and the spline of driving gear are complementary, and the mounting hole 2-1 on the described slide blocks is the oblong aperture that has arc section.Described input shaft 3 axially on be shaped on the slide blocks mounting hole be complementary flat, in the mounting hole of slide blocks, be coated with the input shaft 3 that is used to drive driving gear.
Driving gear adopts floating connecting structure in the gear pump of the present utility model, can make input assembly have the degrees of freedom that X, Y both direction move, and makes gear have good quick condition in high speed rotating, and can effectively reduce the dynamic load of input end.
