Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
As shown in fig. 2 and 3, the utility model provides a coupling, including first axis body 1, second axis body 2, base 3 and gland 4. The first shaft body 1 is provided at a middle portion thereof with a first groove 10 extending in a radial direction thereof. The second shaft body 2 is also provided at its middle portion with a second groove 20 extending in the radial direction thereof. The first shaft body 1 and the second shaft body 2 are vertically arranged during installation, and when the first shaft body 1 and the second shaft body 2 are vertically arranged, the second groove 20 of the second shaft body 2 is reversely buckled on the first groove 10 of the first shaft body 1. In order to prevent the two shafts from being easily deviated due to stress during working, the first inclined teeth 11 are arranged on the bottom surfaces of the first grooves 10, the second inclined teeth 21 matched with the first inclined teeth 11 are arranged on the bottom surfaces of the second grooves 20, namely, when the first shaft body 1 and the second shaft body 2 are vertically installed, the first inclined teeth 11 on the first grooves 10 are meshed and connected with the second inclined teeth 21 on the second grooves 20, so that the contact area of the two shafts which are vertically intersected is increased, the two shafts are prevented from sliding, meanwhile, the bearing capacity of the two shafts can be increased, the service life of the two shafts is prolonged, and the maintenance period of the coupling is prolonged.
The base 3 is provided with a first placing groove (not shown in the figure) matched with the first shaft body 1 and the second shaft body 2 which are vertically arranged, and correspondingly, as shown in fig. 4 and fig. 5, the gland 4 is provided with a second placing groove 40 matched with the first shaft body 1 and the second shaft body 1 which are vertically arranged, and in the embodiment, the first placing groove and the second placing groove 40 are both cross-shaped grooves. The base 3 is further provided with a plurality of bolt holes 30, the gland 4 is also correspondingly provided with a plurality of bolt holes 41, and fasteners such as bolts penetrate through the bolt holes 30 on the base 3 and the bolt holes 41 on the gland 4 to fix the two. In order to improve the life span and the structural stability of the joint, the diameters of the first shaft body 1 and the second shaft body 2 may be set to be equal, and the sum of the depths of the first groove 10 and the second groove 20 may be equal to the diameter of the first shaft body 1/the second shaft body 2, and the sum of the depths of the first placement groove and the second placement groove 40 may also be equal to the diameter of the first shaft body 1/the second shaft body 2.
