Abstract
A shaft coupling comprises a first shaft coupling portion and a second shaft coupling portion and is characterized in that the first shaft coupling portion and the second shaft coupling portion are rotatably connected, and rolling bodies capable of adjusting the concentricity of the first shaft coupling portion and the second shaft coupling portion are arranged at the connecting rotatable position of the first shaft coupling portion and the second shaft coupling portion. Compared with the prior art, the shaft coupling has the advantages that the connecting mode of an existing shaft coupling is improved, an original three-grabbing type rigid connection is changed into a ball type flexible connection in the fixed mode between two shaft couplings, the rotating mode of the shaft coupling is more flexible, the concentricity of the two shaft coupling portions can be adjusted, and use safety and reliability are improved.
Description
Technical field
The utility model relates to a kind of shaft coupling.
Background technique
As shown in Figure 2, for shaft coupling structure common in prior art, this shaft coupling mainly adopts the mode of rigid connection, two a of shaft coupling portion, b of shaft coupling connect by three-pawl type, between a of shaft coupling portion, b, can only realize rotatablely moving around central shaft, Placement is between the two comparatively inflexible, cannot realize the flexible motion of transmission shaft multi-angle.If the connection of transmission shaft and shaft coupling does not put in place or is offset, in transmission process, be easy to spindle nose card is disconnected or damage, and this rigid connection mode makes the stress in transmission process comparatively concentrated, speed the loss of transmission shaft, reduced transmission shaft and life-span.
Model utility content
Technical problem to be solved in the utility model is the shaft coupling that the more flexible and easy accessibility of a kind of and Placement transmission shaft is provided for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of shaft coupling, include the first shaft coupling portion and the second shaft coupling portion, it is characterized in that: the first described shaft coupling portion and the second shaft coupling portion are for being rotatably connected, and described the first shaft coupling portion and the second shaft coupling portion are provided with the rolling element of adjustable both concentricitys at interconnective rotatable position.
As preferably, described rolling element has three and along circumferentially uniform at least.
As further preferably, one end of described the second shaft coupling portion is sheathed on one end of described the first shaft coupling portion, on the inner circle wall of the periphery wall of described first shaft coupling portion one end and described second shaft coupling portion one end, offer respectively can accommodating described rolling element cavity.
As preferably, on the other end of described the first shaft coupling portion, also offer the bearing pin mounting hole of radially offering.
Compared with prior art, the utility model has the advantage of: existing shaft coupling Placement is improved, means of fixation between two shaft couplings is grabbed to formula rigid connection from original three to be improved to ball type and to flexibly connect, make the rotating manner of shaft coupling more flexible, but also can regulate two concentricitys between shaft coupling portion, improve safety in utilization and reliability.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's shaft coupling assembly structure schematic diagram.
Fig. 2 is the shaft coupling assembly structure partial schematic diagram of prior art.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, the present embodiment is a kind of shaft coupling, this shaft coupling includes the first shaft coupling portion 1 and the second shaft coupling portion 2, the first shaft coupling portion 1 and the second shaft coupling portion 2 are for being rotatably connected, wherein, the first shaft coupling portion 1 and the second shaft coupling portion 2 are provided with the rolling element 3 of adjustable both concentricitys at interconnective rotatable position, rolling element 3 is spherical in shape and have three at least, and along circumferentially uniform; One end of the second shaft coupling portion 2 is sheathed on one end of the first shaft coupling portion 1, on the inner circle wall of the periphery wall of first shaft coupling portion 1 one end and second shaft coupling portion 2 one end, offer respectively can accommodating rolling element cavity; In order to facilitate connection for transmission axle, on the other end of the first shaft coupling portion 1 and the second shaft coupling portion 2, can also offer the bearing pin mounting hole 11 of radially offering, between transmission shaft and shaft coupling portion, by the bearing pin being arranged in bearing pin mounting hole 11, be fixedly connected with.
Shaft coupling of the present utility model has adopted ball type flexible connection mode, make the connection between the first shaft coupling portion 1 and the second shaft coupling portion 2 more flexible, not only can realize multi-faceted rotation, and can adjust the concentricity between the first shaft coupling portion 1 and the second shaft coupling portion 2, avoid causing because of rigid connection stress, can effectively extend working life and the operational safety of shaft coupling, improve the overall performance of transmission device.
