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 external gerotor type screw unloading differential centrifugation machine.
Background technology
Differential mechanism is to make rotary drum of horizontal spiral discharge sedimentation centrifuge and auger conveyor produce the transmission device of poor rotating speed, is the critical component of horizontal centrifuge.Extensively adopt at present twin-stage 2K-H satellite differential and traditional Type B or X-type cycloidal-pin wheel differential mechanism both at home and abroad.What the mounting means of the pin tooth in traditional cycloidal-pin wheel differential mechanism adopted is the freely supported structure of two fulcrums, three fulcrum types, and its limitation is:
(1) freely-supported band trocar latch structure must have enough large needle pin diameters for avoiding needle pin to produce excessive flexural deformation, thereby: during speed reducing ratio > 43, most types must be taken out tooth, and result is depression of bearing force;
(2) gear pin produces flexural deformation after bearing cycloidal gear teeth pressure, and flexural deformation is crossed ambassador's gear pin and contacted badly with pin gear sleeve, rotates and dumbly easily causes that gear pin and pin gear sleeve contact-making surface glue together, and cause Cycloidal Wheel and pin tooth gummed.
Summary of the invention
The technical problem that the present invention solves is to take the pin tooth mounting means of sleeping pillow formula, solves the restriction of pin tooth intensity to Cycloidal Wheel bearing capacity.
The technical scheme that the present invention takes is:
A kind of external gerotor type screw unloading differential centrifugation machine, comprise bearing support, power shaft, input case lid, Cycloidal Wheel, pin wheel housing, pin tooth, output shaft, output case lid, screw input feeder and rotary drum, described input case lid upper end is connected with the second belt pulley, input case lid lower end connects pin wheel housing, 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, the pin tooth engagement of described Cycloidal Wheel and pin wheel housing, 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 one end is serially connected with in interior coupling tunnel, the output shaft other end connects screw input feeder, the upper end of described output case lid connects pin wheel housing, the lower end of output case lid connects rotary drum through outreaching extend neck, the described extend neck warp beam that outreaches is held and is serially connected with in supporting base, the sleeping pillow formula of described pin tooth is connected in the axially open through hole of pin wheel housing inner periphery.
Further, on described pin tooth, be socketed with pin gear sleeve.
Again further, on described pin, be socketed with roller.
The present invention takes the beneficial effect of above technical scheme to be: compare with traditional cycloid drive, pin tooth adopts sleeping pillow formula mounting structure, be that whole pin tooth is placed in the open hole on pin wheel housing, compare with traditional two fulcrums, three fulcrum structures, can avoid bending failure and the low failure mode causing of bending stiffness of pin tooth completely.The bearing capacity of pin tooth improves 20-30%, and overall dimensions are dwindled 30-40%.
