At present, the power way of output of powder forming machine is as follows: drive flywheel through belt by motor and rotate, flywheel central authorities are penetrated with power transmission shaft, this power transmission shaft and flywheel coaxial rotation, and flywheel one side is equipped with the aerobraking clutch that the end transmission that exposes with power transmission shaft links to each other, this power transmission shaft is in transmission connection with helical gear, bent axle successively, and the deceleration transmission bent axle, the output of this bent axle is the clutch end of powder forming machine.
Because powder forming machine production requirement speed of crankshaft is at 8-16 rev/min, motor speed is higher, and one-level helical gear transmission speed ratio generally is not more than 10, and this just requires the flywheel rotating speed about 100 rev/mins.The power of crankshaft output end is by the decision of the kinetic energy of flywheel, and the kinetic energy of flywheel is directly proportional with the inertia of flywheel, square be directly proportional with the rotating speed of flywheel, therefore, in order to improve the kinetic energy of flywheel, adopts the inertia of rotating ratio raising flywheel of raising flywheel effective.The transmission speed reducer structure that adopts secondary gear is also arranged at present, improve the rotating speed of flywheel with this, but, the outer transmission of secondary gear deceleration makes the mechanical reduction gear complex structure on frame and the frame, and manufacture difficulty is bigger, and topology layout is unsatisfactory, practice is not ideal enough, requires further improvement.
Summary of the invention
Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of simple in structure, topology layout rationally, be suitable for the gear drive reducing gear on the powder forming machine of practice, this reducing gear does not increase driving gearshaft on frame, large speed ratio can be implemented, thereby higher flywheel rotating speed can be adapted to well.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the gear drive reducing gear of this powder forming machine, the helical gear that comprises the power transmission shaft that is applied in flywheel central authorities, is arranged on aerobraking clutch on power transmission shaft first end, is in transmission connection with power transmission shaft, with the bent axle that the helical gear transmission links to each other, it is characterized in that also including:
Be arranged on the peripheral and centre wheel that rotate synchronously with power transmission shaft of power transmission shaft second end, the uniform and deceleration transmission axle that is engaged on a plurality of planetary gears that are centrosymmetric outside the centre wheel, the big centre wheel that is engaged on a plurality of planetary gears periphery, the planet axis that is arranged on each planetary gear central authorities, a deceleration transmission dish that links to each other with each planet axis, is connected deceleration transmission dish central authorities, wherein, the frame of this big centre wheel and powder forming machine fixes.
As further improvement, described helical gear can comprise active oblique gear that is arranged on the deceleration transmission shaft end and the passive helical gear that is meshed with active oblique gear, wherein, active oblique gear and deceleration transmission axle rotate synchronously, and described bent axle is in transmission connection in these passive helical gear central authorities.Strengthened transmission speed ratio further by active oblique gear and passive helical gear, made bent axle reach working speed and do work.
Compared with prior art, advantage of the present utility model is: the setting by centre wheel, a plurality of planetary gear, big centre wheel, constituted a planetary reduction gear, and strengthen transmission speed ratio, and be not increased in the driving gearshaft on the frame; Reducing gear of the present utility model is simple in structure, topology layout reasonable, be suitable for practice, can implement large speed ratio, thereby can be adapted to higher flywheel rotating speed well.
