Embodiment Construction

[0013] The present invention is described below in conjunction with accompanying drawing.

[0014] as attached figure 2 The shown pear-shaped shaft end baffle according to the present invention includes a baffle body 1, and a first hole 2 and a second hole 3 are opened on the baffle body 1, and the length direction of the baffle body 1 is The ends of the first hole 2 and the second hole 3 are respectively opened with a first groove 4 and a second groove 5 communicating with the outside; the width of the first groove 4 is smaller than the diameter of the first hole 2; The width of the groove 5 is less than the diameter of the second hole 3; the width of the second groove 5 is 1 / 5 of the diameter of the second hole 3; the width of the first groove 4 is 1 / 3 of the diameter of the first hole 2 one.

[0015] In the pear-shaped shaft end baffle of the present invention, since the ends of the baffle body in the length direction are respectively provided with a first groove and a s...

Abstract

The invention relates to a pyriform shaft-end baffle. The baffle comprises a baffle body, and the baffle body is provided with a first hole and a second hole; the ends of the baffle body along the length direction are respectively provided with a first groove and a second groove respectively having the first hole and the second hole communicated with the exterior; and the width of the first groove is less than the diameter of the first hole, and the width of the second groove is less than the diameter of the second hole. According to the pyriform shaft-end baffle of the invention, because the ends of the baffle body along the length direction are provided with the first groove and the second groove respectively making the first hole and the second hole be communicated with the exterior, while the width of the first groove is less than the diameter of the first hole, and the width of the second groove is less than the diameter of the second hole, an allowance is provided for the movement of the pyriform shaft-end baffle; when the load borne by a shaft is too large, the pyriform shaft-end baffle moves tinily, thus the shear strength is satisfied by a fixing bolt, the fixing bolt avoids being sheared, tight locking of the shaft is not easy to fail, and the locking effect is improved.

Description

technical field [0001] The invention relates to a baffle, in particular to a pear-shaped shaft end baffle. Background technique [0002] In mechanical engineering, there are many shafts and assemblies that are articulated, and the shaft is subjected to shear and torsional loads. Therefore, the axial movement and rotation of the shaft must be restricted to prevent accidents and dangers caused by shaft parts falling out of the components. A shaft end baffle can be used to limit the axial movement and rotation of the shaft, and the pear-shaped shaft end baffle is one of the widely used shaft end baffles. The structure of the pear-shaped shaft end baffle of the prior art is as attached figure 1 As shown, it includes a baffle body 1, and the baffle body 1 is provided with a first hole 2 and a second hole 3, the second hole 3 is matched with the shaft, and the first hole 2 is used to fix the entire shaft with fastening bolts. This structure can effectively limit the axial movem...
