The gear shaft fixation hole matched, the gear shaft fixation hole and gear shaft fixed column are to be mounted on the first driving gear, the gear
Axis fixation hole and gear shaft fixed column are equipped with oil storage tank, and oil storage tank can store lubricating oil, make to be able to maintain profit between gear drive
It is sliding, achieve the effect that vibration damping reduces noise, and reduce frictional resistance and slow down and wear between gear, improves the use of the utility model
Service life.
Further, the oil storage tank is annular in shape.
It further, further include the first driven gear, the second driving gear, the second driven gear and in the accommodating cavity
Three driving gears, the motor pass through first driving gear of double end worm-drive, the first driving gear transmission connection institute
The first driven gear is stated, the first driven gear transmission is engaged with the second driving gear, and the second driving gear transmission connects
Second driven gear is connect, second driven gear is engaged with the third driving gear, and the third driving gear passes
The dynamic connection output wheel.
Further, second driving gear lower end is equipped with active ring gear, and the upper end of second driven gear is set
There is driven ring gear, the active ring gear is engaged with driven ring gear, and second driving gear and the second driven gear are logical
Ring gear transmission is crossed, ring gear has the advantages that small in size, compact-sized and transmitting torque is big, when the utility model can be made to overload
Energy " skidding " has protective effect.
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 utility model makes to be able to maintain lubrication between gear drive, reaches vibration damping drop by adding oil storage tank
The effect of low noise, and reduce frictional resistance and slow down and wear between gear, the service life of the utility model is improved, and second
The transmission connection of driving gear and the second driven gear is set as ring gear transmission, can play effectively in the utility model overload
Protective effect.
