Description

Technical Field

[0001] The utility model relates to a bevel gear, in particular to a bevel gear with double grooves on the top. Background Art

[0002] The meshing of bevel teeth realizes the reversal of the rotational force. In the process of cooperation between the rotating shaft and the bevel gear, the axial movement of the bevel gear relative to the rotating shaft is often limited by the cooperation with the step surface on the rotating shaft at the front and rear positions of the bevel gear. However, if the bevel gear is installed at the end of the rotating shaft, the step surface cannot be machined on the rotating shaft to cooperate with the bevel gear.

[0003] In summary, how to limit the fit of the end of the rotating shaft with the bevel gear has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to limit the end of the rotating shaft and the bevel gear;

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] The utility model is a bevel gear with double grooves on the top, comprising: a main body, an axial hole is opened along the axial direction of the main body, and a plurality of threaded holes for connecting the cover plate are opened on the top surface of the main body; the plurality of threaded holes are opened at equal intervals around the axial hole; two positioning grooves are opened radially outward from the axial hole on the top surface, and the two positioning grooves are symmetrically arranged about the circular center of the axial hole;

[0007] In this solution, the rotating shaft is provided with a protrusion that matches the positioning groove. When the rotating shaft is axially inserted into the shaft hole, the protrusion matches the positioning groove. Then the cover plate is set on the top surface of the main body, and the fastener passes through the threaded hole to connect the main body and the cover plate. In this way, the protrusion on the rotating shaft cooperates with the positioning groove to limit the axial movement of the rotating shaft to one side of the main body, and the cover plate cooperates with the end face of the rotating shaft to limit the axial movement of the rotating shaft to the other side of the main body, thereby realizing the limited cooperation between the end of the rotating shaft and the bevel gear.

[0008] In order to ensure the rapid positioning of the cover plate when it is installed on the top surface of the main body, the utility model adopts a semicircular positioning hole extending radially outward from the side wall of the positioning groove away from the shaft hole; the positioning hole is opened along the axial direction of the shaft hole;

[0009] An insertion pin is provided on the surface of the cover plate, which can be inserted into the positioning hole to achieve pre-positioning between the cover plate and the main body. At this time, the hole on the cover plate matches the threaded hole on the main body to achieve a quick connection between the cover plate and the main body.

[0010] In order to illustrate the depth of the positioning hole, the present invention adopts the principle that the bottom wall of the positioning hole is lower than the bottom wall of the positioning groove in the axial direction of the shaft hole;

[0011] In this way, the insertion pin of the cover is inserted into the positioning hole, the height of the insertion pin is greater than the depth of the positioning groove, and the protrusion on the rotating shaft is provided with an arc-shaped notch, which matches the insertion pin, thereby improving the tightness of the fit between the cover, the main body and the rotating shaft.

[0012] The beneficial effects of the utility model are as follows: the utility model is a bevel gear with a double groove on the top, and the rotating shaft is provided with a protrusion matching the positioning groove. When the rotating shaft is axially inserted into the shaft hole, the protrusion matches the positioning groove, and then the cover plate is set on the top surface of the main body, and the fastener passes through the threaded hole to connect the main body and the cover plate. In this way, the protrusion on the rotating shaft cooperates with the positioning groove to limit the axial movement of the rotating shaft to one side of the main body, and the cover plate cooperates with the end face of the rotating shaft to limit the axial movement of the rotating shaft to the other side of the main body, thereby realizing the limited cooperation between the end of the rotating shaft and the bevel gear.

Then the cover plate is set on the top surface of the main body 1, and the fastener passes through the threaded hole 4 to connect the main body 1 and the cover plate. In this way, the protrusion on the rotating shaft cooperates with the positioning groove 5 to limit the axial movement of the rotating shaft to one side of the main body 1, and the cover plate cooperates with the end face of the rotating shaft to limit the axial movement of the rotating shaft to the other side of the main body 1, thereby realizing the limited cooperation between the end of the rotating shaft and the bevel gear.

[0020] like Figure 1-2 As shown, in order to ensure the rapid positioning of the cover plate when it is installed on the top surface of the main body, the utility model adopts a semicircular positioning hole 6 extending radially outward from the side wall 51 of the positioning groove 5 away from the shaft hole 2; the positioning hole 6 is opened along the axial direction of the shaft hole 2;

[0021] An insertion pin is provided on the surface of the cover plate, which can be inserted into the positioning hole 6 to achieve pre-positioning between the cover plate and the main body 1. At this time, the hole body on the cover plate matches the threaded hole 4 on the main body 1 to achieve a quick connection between the cover plate and the main body 1.

[0022] like Figure 1-2 As shown, in order to illustrate the depth of the positioning hole, the present invention adopts the method that the bottom wall of the positioning hole 6 is lower than the bottom wall 52 of the positioning groove 5 in the axial direction of the shaft hole 2;

[0023] In this way, the insertion pin of the cover is inserted into the positioning hole 6, the height of the insertion pin is greater than the depth of the positioning groove 5, and the protrusion on the rotating shaft is provided with an arc-shaped notch, which matches the insertion pin, thereby improving the tightness of the fit between the cover, the main body 1 and the rotating shaft.
