The double-cycloid spiral discharge differential centrifugal machine is characterized in that an inner cycloid gear ring is connected between the input-end case cover and the output-end case cover and is meshed with the cycloid gears.
Description
Technical field
The present invention relates to chemistry, chemical industry, food, medical solid-liquid two-phase separation machinery technical field, relate to specifically a kind of double pendulum line style screw unloading differential centrifugation machine.
Background technology
For in commercial Application, the particle below 2 μ m being carried out the requirement of sedimentation separation, screw unloading differential centrifugation machine must improve the rotating speed of rotary drum, to improve separation factor.Thus, as the differential driver of drive unit require there is the very little radius of gyration, very little rotating mass and very high dynamic balance accuracy, that is to say the lightweight of the essential height of transmission device, appearance and size is minimum as far as possible.Traditional screw unloading differential centrifugation machine using traditional all adopts B, X-type cycloidal-pin wheel as transmission device.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, speed reducing ratio is large, the double pendulum line style screw unloading differential centrifugation machine that bearing capacity is stronger.
The technical scheme that the present invention takes is:
A kind of double pendulum line style screw unloading differential centrifugation machine, comprise power shaft, input case lid, Cycloidal Wheel, hypocycloid gear ring, output shaft, output case lid, screw input feeder, rotary drum and housing, described output case lid is in bearing is serially connected with the endoporus on housing top, the upper end of output case lid is stretched out outside housing and is connected with the second belt pulley, described power shaft is connected to input case lid through bearing, the upper end of power shaft is connected with the first belt pulley, the lower end of power shaft coaxially connects Cycloidal Wheel through capacity eccentric bearing, Cycloidal Wheel is connected with output shaft through pin, described output shaft lower end connects screw input feeder, described output case lid lower surface is connected with rotary drum through coupling tunnel, described coupling tunnel is in bearing is serially connected with the endoporus of lower housing portion, between described input case lid and output case lid, be connected with hypocycloid gear ring, described hypocycloid gear ring and Cycloidal Wheel engagement.
The present invention takes the beneficial effect of above technical scheme to be:
(1) adopt double cycloid structure, with hypocycloid wheel, just replaced the pinwheel being formed by pin wheel housing, a lot of pin tooth and pin gear sleeve, simple in structure, part is few, speed reducing ratio is large.
