Abstract
The utility model discloses the gear transmission structure of a kind of heavy electric hammer, including rotor gear and output gear wheels, output gear wheels include drive drill bit beat motion beat output gear and drive drill bit rotate motion rotation output gear, feature is also to include transition gear assembly, transition gear assembly includes First Transition gear, second transition gear and rotary shaft, First Transition gear is fixedly installed on the lower end of rotary shaft, second transition gear is fixedly installed on the upper end of rotary shaft, the diameter of First Transition gear is more than the diameter of the second transition gear, First Transition gear is meshed with rotor gear, the side of the second transition gear is meshed with beating output gear, the opposite side of the second transition gear is meshed with rotating output gear；Advantage is to add transition gear between rotor gear and output gear, and overall structure reduces, and can save the space of machine, makes machine miniaturization, level Four underdrive make machine torsion bigger, and punching is strong.
Description
Technical field
This utility model relates to the gear transmission structure of a kind of heavy electric hammer.
Background technology
Electric hammer is common electric tool, uses gear drive to realize the running of machine in electric hammer, existing most
The drive mechanism of electric hammer includes rotor gear and the output gear wheels of motor, and output gear wheels include driving drill bit to beat fortune
Dynamic beat output gear and drive drill bit to rotate the rotation output gear of motion, one end of rotor gear with beat output
Gear is meshed, and the other end of rotor gear is meshed with rotating output gear, but this kind of structure overall structure is excessive,
Making electric hammer overall also with becoming big, people are not easy to operation, and this kind of structure output torsion is little, is short of power.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in construction, and the gear of the heavy electric hammer that torsion is big passes
Dynamic structure.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is: the gear drive knot of a kind of heavy electric hammer
Structure, including rotor gear and output gear wheels, it is defeated that described output gear wheels include driving drill bit to beat beating of motion
Go out gear and drive drill bit rotate motion rotation output gear, also include transition gear assembly, described transition gear
It is described that assembly includes that First Transition gear, the second transition gear and rotary shaft, described First Transition gear are fixedly installed on
The lower end of rotary shaft, the second described transition gear is fixedly installed on the upper end of described rotary shaft, the first described mistake
Cross the diameter diameter more than the second described transition gear of gear, described First Transition gear and described rotor gear
Being meshed, the side of the second described transition gear is meshed with described output gear of beating, the second described transition tooth
The opposite side of wheel is meshed with described rotation output gear.
Described First Transition gear is arranged on the left side of described rotor gear, and described rotation output gear is arranged on institute
The left side of the second transition gear stated, described output gear of beating is arranged on the right side of the second described transition gear, institute
The output gear of beating stated is positioned at the top of described rotor gear, saves machine space, makes machine miniaturization, it is simple to make
With.
Compared with prior art, the utility model has the advantage of between rotor gear and output gear, add transition tooth
Wheel, overall structure reduces, can save the space of machine, makes machine miniaturization, level Four underdrive make machine torsion bigger,
Punching is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of gear transmission structure.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As it can be seen, the gear transmission structure of a kind of heavy electric hammer, including rotor gear 1 and output gear wheels, output gear
Wheels include driving drill bit to beat beating output gear 2 and driving drill bit to rotate the rotation output gear of motion of motion
3, also include that transition gear assembly, transition gear assembly include First Transition gear the 41, second transition gear 42 and rotate
Axle 43, First Transition gear 41 is fixedly installed on the lower end of rotary shaft 43, and the second transition gear 42 is fixedly installed on and turns
The upper end of moving axis 43, the diameter of First Transition gear 41 is more than the diameter of the second transition gear 42, First Transition gear
41 left sides being arranged on rotor gear 43 are the most meshed, the right side of the second transition gear 42 with beat output gear 2
Being meshed, the left side of the second transition gear 42 is meshed with rotating output gear 3, beats output gear 2 and is positioned at rotor
The top of gear 1.
