1. in the plastic barrel that connects of speed reducer front end, screw rod is in the condition of high temperature, to cause in decelerating chassis oil temperature to rise, thus must arrange and force oily circulating cooler, so that adds additional manufacture cost and add complete machine weight; 2. the light weight degree of the driving of parallel axes is lower than Gear Planet Transmission, and Gear Planet Transmission comprises planet and the large class of few teeth difference (involute and cycloid) two.
Summary of the invention
For solving deficiency of the prior art, this practical object is to provide and substitutes forced oil cooling radiator cooler to reduce manufacture cost with water-cooled; The existing ZLYJ driving of parallel axes is replaced, to improve the light weight degree of retarder by the multiple tooth cycloid pinwheel planetary gear transmission system to engagement; Bearing capacity is large, volume is little, lightweight a kind of water-cooled plastic extrusion machine cycloid reduction device.
For reaching above object, the technological scheme that the utility model is taked is:
A kind of water-cooled plastic extruder cycloid reduction device, comprise casing and to be arranged in casing and the input shaft of transmission successively, driving mechanism and output shaft, built-in cylinder and cylinder end cap is provided with in described casing, described built-in cylinder is connected to the output terminal of casing and is connected with casing output terminal 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 exterior edge face of built-in cylinder through circular ring cover; Described cylinder end cap is connected to casing input end, and described input shaft is supported on cylinder end cap through two the second bearings, is tightly connected between the end face outside of described cylinder end cap and casing input end end face through circle ring disk; The inner side end of described cylinder end cap is connected with the inner side end of built-in cylinder, and the inwall of described casing and the outer wall of built-in cylinder and cylinder end cap enclose to connect and form airtight folder chamber, and described casing is provided with water inlet and the osculum in the airtight folder chamber of UNICOM.
Further, described driving mechanism comprises capacity eccentric bearing, cycloid wheel, pin wheel housing, pin and needle pin, the bearing hole at described cycloid wheel center is installed on the axle head of input shaft through capacity eccentric bearing, described pin wheel housing is installed on the inner chamber of built-in cylinder, described multiple needle pin is distributed in half buried via hole of pin wheel housing inwall, described cycloid wheel and pin tooth engagement driving, described cycloid wheel is connected with output shaft through pin.
Further, comprise two cycloid wheel, the phase difference of the capacity eccentric bearing that described two cycloid wheel are corresponding is 180 degree.
Further, described needle pin is metal thin-wall spring tube.
Again further, the outer surface of described cylinder end cap and built-in cylinder is provided with multiple heat radiation gusset.
After taking above technological scheme, the beneficial effects of the utility model are:
1. enclose with built-in cylinder, cylinder end cap and cabinet wall and be connected into airtight folder chamber, folder passes into cooling water in chamber, and structure is simple, thus controls, easy to adjust, reliability is high, low cost of manufacture.
2. replace the driving of parallel axes with cycloid wheel transmission, reduce speed reducer volume, weight reduces 50-60%, and cycloidal gear teeth does not exist stress concentration point, and thus never broken teeth, overload capacity are large for cycloid.
