The beneficial effects of the utility model are as follows: the utility model provides a guide rail type sliding end universal joint, which is added with a sliding block, so that the gap between a ball ring and a shell can be enlarged, friction between the ball ring and the shell is reduced, and the service life is prolonged.
Drawings
FIG. 1 is a schematic cross-sectional view of one embodiment of the utility model.
FIG. 2 is a schematic partial cross-sectional view of one embodiment of the utility model.
Detailed Description
The utility model is further described below with reference to the accompanying drawings: as shown in the figure, the guide rail type sliding end universal joint comprises a shell 1 and a tripod head 2, wherein a channel 11 is arranged in the shell, the tripod head comprises a shaft neck 21, a ball ring 22 matched with the channel is arranged on the shaft neck, a track 12 communicated with the channel is arranged in the shell, a sliding block 23 is arranged on the shaft neck, and the sliding block is in sliding fit with the track. The matching of the sliding blocks and the guide rails is increased, so that the ball ring and the shell are not required to be very tight, friction between the ball ring and a channel is reduced, and the service life of the ball ring is prolonged.
In this embodiment, as shown in the figure, the slider has a ring structure. The sleeve is sleeved on the outer side of the shaft neck, so that the processing is better.
In this embodiment, as shown in the figure, the journal is provided with a snap spring 24, the slider is provided with a snap spring above, and the slider is provided with the ball ring below. The upper part is limited by the snap spring, and the lower part is limited by the ball ring, so that the sliding block is kept stable.
In this embodiment, as shown in the figure, a needle roller 25 is disposed between the ball ring and the journal, and the slider is disposed above the needle roller to prevent the needle roller from falling out. The rolling is realized through the roller pin, and the structure is compact.
In this embodiment, as shown, a gap 26 exists between at least one side circumferential sidewall of the slider and the inner wall of the track. Friction is reduced.
In this embodiment, as shown in the figure, three journals are provided, and each journal is provided with the slider.
In this embodiment, as shown in the figure, a stop is disposed at the opening of the channel. The stop block can be a second clamp spring or a bulge which is arranged on the inner wall of the opening of the channel.
In this embodiment, as shown in the figure, the axial end face of the housing is provided with grooves 14 formed by compression, and the grooves are provided on both sides of the opening of the channel. The axial end face of the shell is deformed by jacking such as a center to generate a groove and a bulge arranged on the inner wall of the opening of the channel.
