The worm gear tooth part uses aluminium bronze (ZCuAl10Fe3), and aluminium bronze shrinkage coefficient is small, and has good power
Perfect sliding motion can be formed with the high-precision worm screw of high rigidity, greatly enhance due to its good wearability by learning performance
The service life of worm and gear, in the severe applying working condition especially to run at high speed at 24 hours.
The core wheel uses the high trade mark (QT650) nodular cast iron material.
The operation principle of the present invention is that: when this speed reducer works, power input belt moves worm screw rotation, so that worm gear be driven to turn
Dynamic, when worm gear continuous rotation, eccentric wheel and planetary gear on worm gear are constantly changing in the position of ring gear, make ring gear with
The meshing state of planetary gear also constantly changes, by it is engaging-in, engage, nibble out, disengage, engaging-in again, carry out again and again, thus real
Existing star slow continuous rotation in motion profile；By sliding cross coupling by the power transmission of planetary gear to output shaft
On, thus with dynamic load.
The beneficial effect of technical solution of the present invention is:
The present invention is not that planetary gear is superimposed with the simple of worm and gear, the group in terms of total volume and weight compared with the existing technology
It declines to a great extent under conjunction form；Small in size, light-weight, stable drive；Worm and gear only serves deflecting and torque in transmission
The effect of transmitting substantially increases the service life of worm and gear, and planetary gear is exported as torque, with its superpower carrying energy
Power perfectly plays shock resistance and wear-resisting characteristic.Speed reducer of the present invention is applied to, quality and volumetric spaces size are wanted
It is of great significance in the project asked；The service life of product can be considerably increased in the case where possessing self-locking.
