Abstract
The utility model discloses a novel coupler which comprises a first coupler body and a second coupler body. A stepped through hole is formed in the first coupler body. The small-diameter end of the stepped through hole is provided with a first key groove serving as a first shaft hole. The large-diameter end of the stepped through hole is provided with a plurality of strip-shaped grooves. The second coupler body is provided with a second shaft hole. A second key groove is formed in the second shaft hole. The second coupler body is further provided with a connecting head used for being connected with the large-diameter end of the stepped through hole. The novel coupler is connected with a shaft by adopting a key connecting mode, installing is convenient, the first coupler body and the second coupler body are connected through one-to-one corresponding of the grooves and protruding ridges, and the torque transmission error is small; by means of elastic pads on the protruding ridges, rigid contact between the first coupler body and the second coupler body can be prevented, and therefore the service life of the whole coupler is prolonged.
Description
Technical field
The utility model relates to a kind of mechanical connection mechanism, relates in particular to a kind of novel coupler.
Background technique
Coupling is exactly for connecting two axles (driving shaft and driven shaft) in different institutions and making it common rotation with the mechanical parts of transmitting torque, coupling is comprised of two halves, connect with driving shaft and driven shaft respectively, traditional coupling is not easy coupling and axle to be installed together, and after two half-connection axles connect, transmission of torque error is too large.
Model utility content
The purpose of this utility model provides a kind of novel coupler with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of novel coupler, comprise the first coupling body and the second coupling body, described the first coupling body is provided with ladder hole, the miner diameter end of described ladder hole is provided with the first keyway, and as the first axis hole, the bigger diameter end of described ladder hole is provided with a plurality of strip grooves, described the second coupling body is provided with the second axis hole, in described the second axis hole, be provided with the second keyway, described the second coupling body is also provided with the connecting head for being connected with the bigger diameter end of described ladder hole, described connecting head is provided with a plurality of bar shaped fins, a plurality of described bar shaped fins are corresponding one by one with a plurality of strip grooves.
As preferably, the external shape of described the first coupling body is cylinder type, the central axes of described strip groove and described the first coupling body.
As preferably, the external shape of described the second coupling body and described connecting head is cylinder type, and described the second coupling body and described connecting head are same central shaft, the central axes of described bar shaped fin and described connecting head.
As preferably, the top layer of described bar shaped fin is provided with cushion.
As preferably, the axle connecting end edge of the axle connecting end edge of described the first coupling body and described the second coupling body is provided with fillet.
The beneficial effects of the utility model are:
The utility model mainly adopts key Placement to be connected with axle, easy for installation, and between the first coupling body and the second coupling body by many grooves and many fins corresponding being connected one by one, transmission of torque error is little, and by the cushion on fin, can prevent from producing and firmly contacting between the first coupling body and the second coupling body, thereby extend working life of whole coupling.
