It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic concept of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.

Example 1

As shown in fig. 1 to 3, a novel baffle piece at the end of a rotating shaft comprises a plate body 1, wherein the plate body 1 is square or circular. The surface of the plate body 1 is provided with bolt holes 11. After the snap ring 2 is snapped on the groove ring at the end of the rotating shaft, the plate body 1 is fixed on the surface of the bearing seat in a bolt fixing mode.

The middle part of the plate body 1 is fixedly embedded with a snap ring 2; the clamping ring 2 is provided with a groove section and consists of a left annular wall 21, a bottom annular wall 23 and a right annular wall 22 which are integrally formed; the left annular wall 21 and the right annular wall 22 are respectively and vertically provided with a sliding groove 5; the sliding groove 5 is elongated and has a length greater than the radial dimension of the roller 31, so that the roller 31 can be inserted into the groove in the snap ring 2 as a whole.

The rolling mechanisms 3 are uniformly arranged on the inner side of the buckling ring 2; the rolling mechanism 3 comprises a fixed rod 32, and two ends of the fixed rod 32 respectively penetrate through the sliding grooves 5 on the left annular wall 21 and the right annular wall 22 and slide along the sliding grooves 5; specifically, the fixing rod 32 includes a round rod segment 3201 and rectangular segments 3202 at two ends of the round rod segment 3201; the rectangular section 3202 is slidably arranged in the sliding grooves 5 on the left annular wall 21 and the right annular wall 22; the rod segment 3201 is located between the left side annular wall 21 and the right side annular wall 22. Because the two ends of the round rod 3201 are slightly rectangular 3202, and the rectangular 3202 is embedded in the elongated sliding groove 5, when the round rod 3201 in the middle rotates, the fixing rod 32 cannot rotate under the limit of the rectangular 3202.

In order to further prevent the fixing rod 32 from rotating and the fixing rod 32 from moving in the axial direction, the sides of the rectangular section 3202 are respectively provided with a groove 3203; the inner wall of the sliding groove 5 is vertically and symmetrically provided with convex strips 51; the protruding strips 51 are slidably fitted in the grooves 3203. The two ends of the fixing rod 32 are respectively provided with a limiting block 33.

A roller 31 is sleeved in the middle of the fixed rod 32, and the roller 31 is positioned between the left annular wall 21 and the right annular wall 22; the roller 31 is used for contacting with the surface of the groove ring of the rotating shaft, when the rotating shaft rotates, the friction force between the clamping ring 2 and the rotating shaft is reduced, and the service life of the baffle piece and the rotating shaft is prolonged.

In order to facilitate the sleeving of the snap ring 2 on the groove ring at the end of the rotating shaft, an elastic mechanism 4 is further arranged inside the snap ring 2 and used for controlling the resilience of the rolling mechanism 3. The elastic mechanism 4 comprises a sleeve-connection piece 43 and a fixing piece 41, the fixing piece 41 is fixed on the inner wall of the snap ring 2, and the sleeve-connection piece 43 is sleeved on the fixing rod 32; an elastic piece 42 is arranged between the sleeve 43 and the fixed piece 41.

Specifically, the elastic member 42 is configured as a spring or a leaf spring.

The working mode of the baffle piece is as follows: the baffle piece is mainly used for axially limiting and fixing the end part of the transmission shaft. And a corresponding groove ring is processed at the end part of the unpowered end of the rotating shaft and is used for being embedded with the clamping ring of the baffle piece. During the installation, cup joint this baffle spare in the groove ring department of pivot, because rolling mechanism 3 on the buckle ring 2 is under the effect of elastic mechanism 4, can press in the recess on buckle ring 2, the one side slant of buckle ring 2 cup joints on the groove ring this moment, then just return this baffle spare, make the opposite side and the groove ring of buckle ring 2 aim at, this moment, under elastic mechanism 4's rebound, all cylinders 31 on the buckle ring 2 all with the surface contact of groove ring, and simultaneously, adopt the bolt to fix plate 1 on the bearing frame, and then realized that the axial of countershaft is spacing.

Meanwhile, the rotation of the rotating shaft is not hindered due to the contact between the roller 31 and the groove ring.

The baffle piece is sleeved at the end part of the rotating shaft and is fixed with the bearing seat, so that the rotating shaft can be prevented from axially sliding in the rotating process, and the stability of the rotating shaft in rotation is further ensured.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
