Abstract
The utility model relates to an externally-arranged double-swing type screw unloading differential centrifuge. A second belt wheel is connected to the upper end of an input end box cover. An input shaft penetrates through the input end box cover. A first belt wheel is connected to the upper end of the input shaft. The lower end of the input shaft is connected with a cycloidal gear coaxially through an eccentric bearing. The cycloidal gear is connected with an internal connecting barrel through a column pin. The internal connecting barrel is connected with the inside of an output box cover through a bearing. The upper end of an output shaft is connected with the inside of the internal connecting barrel in series. The lower end of the output shaft is connected with a spiral material conveying device. The lower end face of the output end box cover is connected with a rotary drum through an external connecting barrel. An internal cycloidal gear ring is connected between the input end box cover and the output end box cover. The internal cycloidal gear ring is meshed with the cycloidal gear.
Description
Technical field
The utility model relates to chemistry, chemical industry, food, medical solid-liquid two-phase separation machinery technical field, relates to specifically a kind of external double pendulum line style screw unloading differential centrifugation machine.
Background technology
For the requirement of in commercial Application, the particle below 2 μ m being carried out sedimentation separation, screw unloading differential centrifugation machine must improve the performance of centrifuge, and the crucial rotating speed that is to improve rotary drum, to improve separation factor.Thus, as the differential driver of drive unit, also owing to improving main transmission rotating speed, require 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
It is a kind of simple in structure that the purpose of this utility model is to provide, and speed reducing ratio is large, the external double pendulum line style screw unloading differential centrifugation machine that bearing capacity is stronger.
The technical scheme that the utility model is taked is:
A kind of external double pendulum line style screw unloading differential centrifugation machine, comprise bearing support, power shaft, input case lid, Cycloidal Wheel, output shaft, output case lid, screw input feeder and rotary drum, described input case lid upper end is connected with the second belt pulley, described power shaft is connected to input case lid, power shaft upper end is connected with the first belt pulley, power shaft lower end coaxially connects Cycloidal Wheel through capacity eccentric bearing, described Cycloidal Wheel is connected with interior coupling tunnel through pin, described interior coupling tunnel warp beam is held and is connected in output case lid, output shaft upper end is serially connected with in interior coupling tunnel, output shaft lower end connects screw input feeder, described output case lid lower surface is connected with rotary drum through outreaching extend neck, it is characterized in that, between described input case lid and output case lid, be connected with hypocycloid gear ring, described hypocycloid gear ring engages with Cycloidal Wheel.
The utility model 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.
(2) double cycloid pure rolling mesh, engagement normal radius of curvature is little, and contact strength is high, and bearing capacity can improve 50-70%.
