Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 3, the utility model adds the fixed shaft sleeve 4 on the basis of the original quincunx universal driving shaft, the fixed shaft sleeve 4 arranged on the two sides of the driving half shaft 1 and the driven half shaft 2 is directly connected with the transmission shaft, when the inside of the shaft coupling is damaged by friction, the fixed shaft sleeve 4 can be taken down, the shaft coupling can be directly replaced, the replacement is simple and convenient, meanwhile, in order to prolong the service life of the shaft coupling, the buffer gasket 9 is arranged between the driving half shaft 1 and the driven half shaft 2, the abrasion between the components is effectively delayed, the replacement frequency of the shaft coupling is reduced, the efficiency is improved, and the cost is saved;

the driving half shaft 1 and the driven half shaft 2 are connected with a fixed shaft sleeve 4 through bolts 3, a plurality of threaded holes 5 are formed in the side faces of the driving half shaft 1 and the driven half shaft 2, shaft sleeve holes 6 which are the same as the threaded holes 5 in size are formed in the upper end and the lower end of the fixed shaft sleeve 4, and the bolts 3 penetrate through the threaded holes 5 and the shaft sleeve holes 6 to enable the driving half shaft 1 and the driven half shaft 2 to be connected with the fixed shaft sleeve 4 respectively and form an integrated structure.

In this embodiment, fixed axle sleeve 4 is fixed with the transmission shaft, rotates under the drive of transmission shaft, and the shaft coupling is connected with fixed axle sleeve 4, therefore the shaft coupling rotates to the transmission rotates, reaches the rotation of driven shaft, and because the existence of fixed axle sleeve 4, change the shaft coupling and only need take off bolt 3, the shaft coupling can take off, reaches the purpose of convenient change.

The end faces, far away from the fixed shaft sleeve 4, of the driving half shaft 1 and the driven half shaft 2 are respectively provided with a plurality of disc teeth 7 protruding outwards, a plum blossom elastomer 8 is arranged between the disc teeth 7, and buffer gaskets 9 in the same shape with the plum blossom elastomer 8 are arranged on two sides of the plum blossom elastomer 8.

The cushion pad 9 comprises an inner ring 901 and a plurality of plum-petal-shaped teeth 902, the plum-petal-shaped teeth 902 are fixedly connected to the outermost circumferential surface of the inner ring 901, a support framework 903 is fixedly connected to the inside of the cushion pad 9, and the support framework 903 is used for increasing the hardness of the cushion pad 9.

It should be added that the supporting framework 903 is an integrated structure, the cushion pad 9 is made of polyurethane material and is integrally poured on the supporting framework 903, the supporting framework 903 is completely sealed on the cushion pad 9, the supporting framework aims to provide a supporting plasticity effect for the cushion pad 9, and when the cushion pad 9 is squeezed and rubbed by the driving half shaft 1 and the driven half shaft 2, the plastic cushion pad 9 is effectively supported, so that the rubbing effect is delayed.

Be provided with bump 10 on the plum blossom elastomer 8, and the interval is provided with mounting hole 904 on the plum blossom petal type tooth 902, and plum blossom petal type tooth 902 cup joints on bump 10 through mounting hole 904 to buffer pad 9 is connected with plum blossom elastomer 8.

Wherein, bump 10 not only can use with the mounting hole 904 cooperation, reaches the effect of installation buffer gasket 9, still unanimous with the effect of supporting skeleton 903, if do not have the existence of bump 904, buffer gasket 9 directly contacts with initiative semi-axis 1 and driven semi-axis 2, in the transmission process, constantly rubs and extrudees, and the degree of wear is serious, buffer gasket 9 when having increased bump 10 most not with initiative semi-axis 1 and driven semi-axis 2 direct contact to reach the effect that delays wearing and tearing.

The quincunx-shaped teeth 902 are mutually clamped and connected with the disk teeth 7 on the driving half shaft 1 and the driven half shaft 2 at intervals, the number of the quincunx-shaped teeth 902 is the sum of the number of the disk teeth 7 on the driving half shaft 1 and the driven half shaft 2, and the number of the disk teeth 7 on the driving half shaft 1 is equal to that of the disk teeth 7 on the driven half shaft 2.
