Description
Technical field: the utility model relates to a kind of strong power transfer unit that is applied to vacuum vessel and other seal container, the powerful non-contact coupling of specifically a kind of high pulling torque power transmitting deice that is applied on the metal nano powder manufacturing equipment---combined type, this coupling can pass to driven shaft with the effect by magnetic force of the power of driving shaft, rotates synchronously thereby drive driven shaft.
Background technique: the nanometer powder material is the high-tech material that receives much concern that grows up the end of the eighties, the manufacturing development of nano-powder is very fast, manufacturing equipment for metal nano powder, need under the state of high vacuum, work, it is very difficult that each transmission position of whole system keeps lasting high-seal, existing transmission position is directly transmission of power to be come in and in addition Sealing sealing on axle, owing to the reasons such as mechanical vibration of transmission shaft make whole sealing system can not keep highly lasting sealing, high-revolving if desired in addition power, Sealing and transmission shaft high-speed friction are exceedingly fast sealing part abrasion, and this just needs often to change the Sealing of wearing and tearing.Make the entire equipment system-down.It is very inconvenient to operate.Also need special processing in addition, otherwise can make the nanometer powder oxidation.Even burning, thereby influenced production, caused economic loss.
In addition, because nanometer powder manufacturing equipment and miscellaneous equipment need the high pulling torque transferring power mostly.Non-contact coupling before can not satisfy its demand, because the magnetic patch of the contactless coupling of axial disk before is excessive as making, its magnetic force has very big axial force to axle, this axial force is very big to the influence in working life of rotating support bearing, it is reduced significantly, even use thrust-bearing can not avoid its influence fully.Its equipment bearing needs often to change, and very trouble operates.If use before the radially contactless coupling of cartridge type, because processing between the driving shaft driven shaft and assembly error make its axial clearance have certain error, this error is to small size, and the influence of the coupling of little moment of torsion not quite can be used; But needing the high pulling torque transmission is the radially diameter and the axial thickness size of tube that will increase the non-contact coupling, because the gap of non-contact coupling magnetic patch to the magnetic force influence greatly, this has bigger moment difference with regard to the moment that makes the error gap lead its radial magnetic force of system, thereby the swivel bearing of leading the system transmission shaft is radially because of this bigger torque difference unbalance stress, in the running, greatly reduce its working life, need periodic replacement, and when the operation of vacuum nano equipment, change very difficulty of bearing, must use specific process, whole process bothers very much; When the nanometer powder of production active metal, even may not change; Otherwise misoperation can cause oxidation even blast.Cause very big loss.
Summary of the invention: the purpose of this utility model is will provide a kind of dynamic seal (packing) can be converted into static sealing, and it is simple into flexible drive mechanism to become positive drive, good sealing effect, and can transmit than the powerful contactless coupling of the combined type of high pulling torque.
The purpose of this utility model is to realize like this, this coupling comprises driving shaft, active connecting shaft body, driven shaft, driven connecting shaft body, seal diaphragm, permanent magnet, its active connecting shaft body is arranged on the driving shaft, driven connecting shaft body is arranged on the driven shaft, be provided with permanent magnet above active connecting shaft body and the driven connecting shaft body, have the gap in the middle of initiatively connecting shaft body and driven connecting shaft body are embedded in together, in the gap together of active connecting shaft body and driven connecting shaft body, be provided with seal diaphragm.
Described active connecting shaft body and driven connecting shaft body are radially cartridge type coupling cylindrical body or the cones that has a plurality of annular recess and annular projection.
Described active connecting shaft body is that the cross section is " mountain " word shape or is the cylindrical body of " recessed " word shape.
Described driven connecting shaft body is cylindrical body or the cone that the cross section is " recessed " word shape.
The magnetic pole arranged alternate of the permanent magnet on described active connecting shaft body and the driven connecting shaft body.
The utility model is owing to adopt said structure to have above advantage:
1, the transmission of this coupling moment of torsion realizes by magnetic force, realize static sealing by intermediate clapboard or middle spacer sleeve, when driving shaft rotate, initiatively between connecting shaft body and the driven connecting shaft body under the effect of magnetic force the realization lotus root close, promptly utilize the permanent magnet same sex to repel each other, there is a natural attraction between the sexes.Driving driven shaft rotates synchronously.
2, this coupling is owing to adopt said structure energy transmitting large torque power, and permanent magnet is because this cooperative action power is big, and the transmitting large torque power safety is reliable.
3, this coupling is the non-contact coupling, the transmission of moment of torsion is to realize by magnetic force, this coupling dress is deposited in the vacuum vessel, dividing plate separates primary shaft and driven shaft between two connecting shaft bodies, driven shaft is sealed by spacer, prime mover and bearing are not passed in dust, vibration that driven machine is produced in the course of the work, make dynamic seal (packing) be converted into static sealing.Guaranteed driven shaft and system sealing, under the transmission situation that realizes moment of torsion, can keep the degree of vacuum of seal of vessel and container for a long time, this just guarantees the vacuum requirement of metal nano powder preparation.
4, because this coupling is contactless, by magnetic drives, so when overload occurring, two connecting shaft bodies can produce relative movement skid unlikely damage prime mover and working machine main shaft realization overload protection because of the action range that exceeds magnetic force.
