Further technical scheme of the present invention is: described planetary reduction gear is the right angle planetary reduction gear that includes vertical end and transverse end, described servomotor vertically is fixedly mounted on fixed frame, the output shaft of this servomotor is connected with the vertical end of right angle planetary reduction gear, and the transverse end of right angle planetary reduction gear is passed bearing holder component and is connected with an end of shaft coupling.
Owing to adopting said structure, the present invention's screw in injection molding machine electric charging mechanism compared with prior art, has following beneficial effect:
1. cost is low:
Replaced hydraulic oil motor to drive screw rod because the present invention's screw in injection molding machine electric charging mechanism adopts servomotor, its drive disk assembly is less, and it is shorter, relatively simple for structure that rotary power transmits distance, so cost is lower, has higher cost performance.
2. installing space is little:
Because the present invention adopts planetary reduction gear and servomotor combination, screw rod is driven, planetary reduction gear small volume wherein, and linear pattern and perpendicular type arranged, can be according to the different needs of machine, servomotor is mounted to and vertical, level and axially installing, can make compact conformation reasonable, reduce installing space.
3. noise is low:
Slow down because the present invention adopts planetary reduction gear, because planetary reduction gear itself has smooth running, characteristics that noise is low, therefore, noise of the present invention is lower.
4. efficiency is high:
Replaced hydraulic oil motor to drive screw rod because the present invention adopts servomotor, can carry out die sinking, thimble and locked mode in reinforced, thereby can shorten about 20-30% circulation timei, greatly improved the operation of a machine efficiency, be easy to apply.
5. applicable on the higher injection machine of precision requirement:
, because planetary reduction gear of the present invention can adopt the micron order planetary reduction gear, on the higher injection machine of precision requirement, and make the control accuracy of injection machine can be to the accurate digital control future development.
6. planetary reduction gear is mainly used on automobile, Digit Control Machine Tool, and use this element on injection machine, be equivalent to automobile, Digit Control Machine Tool mature technology are shifted to the injection machine aspect, greatly promoted the technology content of injection machine, skill upgrading and the upgrading of injection machine industry had extremely important meaning.
