Background technology
Existing ZLYJ plastic speed reducer special for extruder be ZLY type two-stage parallel axis hard-tooth surface gear reduction unit thrust bearing is set, in order to bear the improvement type of plastics machine screw rod axial force, have that volume is little, bearing capacity is high, stable drive, noise are low, efficiency high.Add up according to reductor industry sources, ZLYJ plastic speed reducer special for extruder, be that the existing domestic market amount of having is maximum, copy one of most special reduction gear product of producer.There are following two big defects in ZLYJ plastic speed reducer special for extruder:
1. in the plastic barrel that reductor front end couples, screw rod is in the condition of high temperature, and in causing decelerating chassis, oil temperature rises, thus must arrange the oil circulation chiller of pressure, so that adds additional manufacturing cost and adding complete machine weight；2. the light weight degree of the driving of parallel axes is lower than Gear Planet Transmission, and Gear Planet Transmission includes planet and the big class of few teeth difference (involute and cycloid) two.
Summary of the invention
For solving deficiency of the prior art, it is an object of the invention to provide and substitute forced oil cooling radiator cooler to reduce manufacturing cost with water-cooled；The existing ZLYJ driving of parallel axes is replaced, to improve the light weight degree of decelerator by the multiple tooth cycloid pinwheel planetary gear transmission system to engagement；Bearing capacity is big, volume is little, lightweight a kind of water-cooled plastic extrusion machine cycloid reduction device.
For reaching object above, the technical scheme that the present invention takes is:
A kind of water-cooled plastic extruder cycloid reduction device, including casing be arranged in casing and the power shaft of transmission, drive mechanism and output shaft successively, built-in cylinder and cylinder end cap it is provided with in described casing, described built-in cylinder is connected to the outfan of casing and is connected with casing outfan end face through flange, described output shaft is supported on built-in cylinder through two clutch shaft bearings, the external part of described output shaft is socketed with thrust cylinder, and described thrust cylinder is fixedly connected on the outer face of built-in cylinder through circular ring cover；Described cylinder end cap is connected to casing input, and described power shaft is supported on cylinder end cap through two the second bearings, is tightly connected through circle ring disk between the end face outside of described cylinder end cap and casing input end face；The inner side end of described cylinder end cap is connected with the inner side end of built-in cylinder, and the outer wall of the inwall of described casing and built-in cylinder and cylinder end cap encloses and connects the airtight folder chamber of formation, and described casing is provided with inlet opening and the apopore in UNICOM's airtight folder chamber.
Further, described drive mechanism includes capacity eccentric bearing, Cycloidal Wheel, pin wheel housing, pin and needle pin, the dead eye at described Cycloidal Wheel center is installed on the axle head of power shaft through capacity eccentric bearing, described pin wheel housing is installed on the inner chamber of built-in cylinder, the plurality of needle pin is distributed in half buried via hole of pin wheel housing inwall, described Cycloidal Wheel and pin tooth engaged transmission, described Cycloidal Wheel is connected with output shaft through pin.
Further, including two Cycloidal Wheel, the phase contrast of the capacity eccentric bearing that described two Cycloidal Wheel are corresponding is 180 degree.
Further, described needle pin is metal thin-wall elastic tube.
Yet further, the outer surface of described cylinder end cap and built-in cylinder is provided with multiple heat radiation gusset.
After taking above technical scheme, the invention have the benefit that
1. enclosing with built-in cylinder, cylinder end cap and cabinet wall and be connected into airtight folder chamber, folder is passed through cooling water in chamber, simple in construction, thus control, easy to adjust, reliability is high, low cost of manufacture.
2. replacing the driving of parallel axes with Cycloidal Wheel transmission, reduce reductor volume, weight reduction 50-60%, there is not stress concentration point in cycloidal gear teeth, thus cycloid never broken teeth, overload capacity are big.
