Description
Technical field
The present invention relates to gear technique field more particularly to a kind of gear box structures with oil groove.
Background technique
Gear drive is one of most common machine driving form, is applied in life and industry manufacture, in various gears
In driving form, the gear teeth from initially enter be engaged to disengagement during there is frictions, in any gear drive, the flank of tooth
If directly engaged, two flank of tooth may occur and stick, tooth surface abrasion fever causes gear imminent failure.Therefore gear
The basic demand of lubrication is exactly the field of conjugate action that lubricating oil has to enter into gear, forms effective lubricating film and separates the flank of tooth, prevents to nibble
The material for closing the flank of tooth directly contacts, and the heat generated due to friction is taken away quickly, guarantees the normal operation of gear.
But in Meshing Process of Spur Gear, lubricating oil can be gradually extruded from the flank of tooth, need irregular make-up oil, such as
Fruit is supplemented not in time, it will influences the service life of gear set, is more especially equipped with the product of cam drive connection, work
When gear set suffered by active force it is larger, if lubrication is insufficient, service life will be greatly shortened, the engagement between gear
Also the cavity that can be generated in huge noise or even gear-box can also be expanded because of fever, to influence the steady of gear set work
It is qualitative.
Summary of the invention
Keep stability between gear drive good in view of this, the present invention provides one kind, be both able to maintain lubrication, reaches vibration damping drop
The effect of low noise, and reduce frictional resistance and slow down and wear between gear, the gear box structure improved service life.
In order to solve the above-mentioned technical problem, the technical solution used in the present invention are as follows:

Gear shaft fixation hole, first driving gear is mounted in gear shaft fixation hole, and storage is equipped in the gear shaft fixation hole
Oil groove.
Further, the oil storage tank is located at the aperture of gear shaft fixation hole, and the bottom width of the oil storage tank is from leaning on
Aperture one end of nearly gear shaft fixation hole gradually becomes smaller to the other end close to output wheel, and the depth of the oil storage tank is with bottom surface
Width reduction correspondingly gradually becomes smaller.
Further, it is 90 ° -120 ° that the side in the oil storage tank and bottom surface, which form angle,.
Further, at least one oil storage tank is arranged in the gear shaft fixation hole.
It further, further include double-thread worm, the second driving gear, the second driven gear, third master in the accommodating cavity
Moving gear and third driven gear, the motor are engaged by double-thread worm with third driving gear, the third driving gear
Be sequentially connected the third driven gear, and the third driven gear transmission is engaged with the second driving gear, and described second actively
Gear lower end is equipped with active ring gear, and the upper end of second driven gear is equipped with driven ring gear, the active ring gear with
The engagement of driven ring gear, second driving gear are driven the second driven gear by ring gear, second driven gear and
The first driving gear engagement, the first driving gear transmission connection output wheel.
Further, the bottom cover bottom is provided with a motor base, and the motor is arranged in the motor base.
Further, the end cap is clamped the bottom cover.
The utility model has the advantages that the problem of present invention is by adding oil storage tank, avoiding gear-box internal heat generation expansion effects stability,
Both made to be able to maintain lubrication between gear drive, and achieved the effect that vibration damping reduced noise, and reduced frictional resistance again and slow down gear
Between wear, improve service life of the invention, and be set as being preced in the transmission connection of the second driving gear and the second driven gear
Gear drive can be played the role of being effectively protected in present invention overload.

Specific embodiment
With reference to the accompanying drawing, embodiments of the present invention are specifically illustrated, attached drawing is only for reference and illustrates use, does not constitute pair
The limitation of the invention patent protection scope.
Please refer to Fig. 1-5, a kind of gear box structure with oil groove, including end cap 1 and bottom cover 2, the end cap 1 and bottom cover 2
An accommodating cavity 3 is formed, the accommodating cavity 3 is interior driven including double-thread worm 8, the first driving gear 5, the second driving gear 6, second
Gear, third driving gear 7 and third driven gear, the motor 4 are engaged by double-thread worm 8 with third driving gear 7, are
Raising transmission efficiency, the third driving gear 7 are helical gear, the third driving gear 7 be sequentially connected the third from
Moving gear, the third driven gear transmission are engaged with the second driving gear 6, and second driving gear 6 is sequentially connected described
Second driven gear, second driven gear 6 are engaged with first driving gear 5, and the output wheel 10 is inlaid in first
On the end axis of driving gear 5.
In order to improve service life of the invention, 6 lower end of the second driving gear is equipped with active ring gear 61, and described the
The upper end of two driven gears is equipped with driven ring gear 62, and the active ring gear 61 is engaged with driven ring gear 62, and described second
Driving gear 6 and the second driven gear are driven by ring gear, and ring gear has small in size, compact-sized and big transmitting torque
Advantage when the present invention can be enable to overload " skidding ", has protective effect.
In the present embodiment, the end cap 1 includes gear shaft fixed column 11, and the bottom cover 2 is equipped with and gear shaft fixed column
