Description
Technical field
The utility model relates to a kind of shaft coupling, relates in particular to a kind of shaft coupling that can utilize the magnetic field buffering.
Background technology
As everyone knows, shaft coupling is for connecting two axles (driving shaft and driven shaft) in different institutions, thereby makes it the machine components of common rotation with transmitting torque.Shaft coupling is for playing the effect of transmitting torque.In the power transmission of high-speed overload, it is the effect of dynamic property that some shaft coupling also has buffering, vibration damping and raising axle.Shaft coupling is comprised of two halves, with driving shaft and driven shaft, connects respectively.General engine major part all links by means of shaft coupling and working machine, is that the engineering goods axle is the most frequently used link of transmission.Shaft coupling commonly used has diaphragm coupling, gear coupling, plum coupling, oldham coupling, drum-shaped tooth type shaft coupling, Hooks coupling universal coupling, safety coupling, spring coupling and Falk flexible coupling.The two halves of traditional shaft coupling is directly contact connection usually, for example by gear structure, is connected with a joggle, to realize the transmission of moment of torsion.But, in the process of transmitting torque, this contact connected mode between the two halves of shaft coupling can produce larger friction, can cause wearing and tearing to the two halves structure.Because shaft coupling is metal structure, when friction, usually also can produce larger noise, the existing shaft coupling that the magnetic field transmitting torque is also arranged simultaneously.
Such as China invention bulletin CN103117686A, relate to mechanical spare part in common use field, be specifically related to a kind of shaft coupling.Shaft coupling comprises: driving shaft, and it is provided with the first magnet, and this first magnet comprises a plurality of sub-magnet according to Haier's Bake array arrangement; Driven shaft, it is provided with the second magnet, and this second magnet comprises a plurality of sub-magnet according to Haier's Bake array arrangement; Described the first magnet and described the second magnet are pulled together, and wherein, when described driving shaft drives described the first magnet and rotated, described the first magnet drives described the second magnet and rotated, and described the second magnet drives described driven shaft and rotated.
Though but but above-mentioned utility model utilizes the less moment of torsion that can transmit of magnetic field transmission moment of torsion magnetic pole opposite face less.
The utility model content
In order to solve the very easily damaged shortcoming of the existing less and common shaft coupling cushion pad of magnetic shaft coupling transmitting torque, the utility model provides a kind of magnetic resistance shaft coupling.
The utility model solves the technical scheme that its technical problem adopts: a kind of magnetic resistance shaft coupling, comprise interconnective major joint and from joint, the major joint end face is provided with circular pit, circular pit axis and major joint axis coaxle, the circular pit sidewall is provided with protruding driving magnetic patch, be provided with pillow block from the joint end face, the pillow block side is provided with the passive magnetic patch of projection, the major joint end face with from the joint end face, coordinate and passive magnetic patch the space driven between magnetic patch, passive magnetic patch is identical with the mating surface polarity of adjacent driving magnetic patch.
Further described, described driving magnetic patch is uniformly distributed and is at least one along the pit sidewall, drives between magnetic patch and leaves gap.
Further described, described passive magnetic patch width is less than the gap width driven between magnetic patch.
Further described, described passive magnetic patch is uniformly distributed along the pillow block side.
The beneficial effects of the utility model are: main connection and from being distributed with the magnetic field of repelling each other between connector, during the normal delivery moment of torsion, utilize the magnetic field carry-over moment to avoid major joint and collided from joint, also avoided the more simple situation of also having avoided the cushion pad wearing and tearing and having damaged of use structure of the cushion pad of existing use shaft coupling to occur, in the situation that the larger magnetic patch of transmitting torque contacts with each other, the situation of the deficiency that effectively compensated the magnetic field transmitting torque is compared and is had the less deficiency of magnetic coupling driving torque now simultaneously simultaneously.
