Detailed Description
It is to be understood that, according to the technical solution of the present utility model, those skilled in the art may propose various alternative structural modes and implementation modes without changing the true spirit of the present utility model. Accordingly, the following detailed description and drawings are merely illustrative of the utility model and are not intended to be exhaustive or to limit the utility model to the precise form disclosed.
As shown in fig. 1-2, a sliding block type coupling comprises a shaft body, flange fork heads are fixedly arranged at two ends of the shaft body, one end of each flange fork head is connected with a movable flange fork head through a first cross shaft assembly, the other end of each flange fork head is connected with a shaft sleeve body 1 through a second cross shaft assembly, the shaft sleeve body 1 is of a semi-closed structure, namely, of a barrel-shaped structure with one side open, and the flat heads can be embedded into the shaft sleeve body 1 from the opening to finish power transmission. The positioning groove 2 is symmetrically arranged on the inner wall of the shaft sleeve body 1, the flat key 3 is embedded in the positioning groove 2, the positioning ring 4 is fixedly arranged at the opening of the shaft sleeve body 1 by bolts, when the coupler works, the flat key 3 is stressed to transmit torque, and the positioning ring 4 plays a role in centering.
The chamfer is machined at the two ends of the inner side of the positioning groove 2, the chamfer is also machined at the two ends of the side, facing the shaft sleeve body 1, of the flat key 3, and abrasion of the inner side of the flat key 3 and the positioning groove 2 can be reduced through the machined chamfer.
The thickness of the flat key 3 is not greater than the depth of the positioning groove 2, namely, the flat key 3 is positioned in the positioning groove 2 and can just fill the positioning groove 2 at most, and thus, the flat key is matched with the inner wall of the shaft sleeve body 1 to form a position suitable for embedding the flat head. The inner diameter of the positioning ring 4 is not larger than the inner diameter of the shaft sleeve body 1, namely, the positioning ring 4 can completely cover the opening of the shaft sleeve body 1, so that the flat key 3 is limited to a certain extent while the centering effect is achieved.
