Description

Technical Field

[0001] The utility model relates to the technical field of gears, in particular to a gear with an external connection structure. Background Art

[0002] A gear is a mechanical transmission element consisting of a gear shaft and a gear, which can transmit speed and torque through the meshing between gear teeth.

[0003] The previous gears have the following disadvantages: 1. The gears are directly connected to the external output shaft by bolts, but the direct connection will make the output shaft easy to deform. In order to avoid this problem, discs are set on both the gears and the external output shaft, and then the output shaft and the gears are connected by the discs. In the past, the gears did not have a structure for connecting with the external disc-shaped connector, and did not have a pre-positioning structure that can adjust the width when connected, which is not convenient and fast enough when connecting with the external disc-shaped connector. To this end, we propose a gear with an external connection structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a gear with an external connection structure, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A gear with an external connection structure comprises a hollow cylinder, a gear body and a disc body, wherein the disc body is arranged on the periphery of the top end of the hollow cylinder, a guide groove is opened at the top of the disc body near the edge, a fixed vertical plate is welded at the top of the disc body near the inner side of the guide groove, an adjusting screw is arranged at one end of the fixed vertical plate through a threaded groove, a bearing is arranged on the periphery of the end of the adjusting screw, a displacement plate is connected to the end of the bearing, and the bottom end of the displacement plate is located in the guide groove.

[0007] Furthermore, the disc body is provided with connecting bolts through screw holes near the edge, and the connecting bolts facilitate the connection between the disc body and the connecting disc on the external output shaft.

[0008] Furthermore, a reinforcing rib plate is welded to the outside of the hollow cylinder, one end of the reinforcing rib plate is connected to the gear body, and a connecting plate is welded to the other end of the reinforcing rib plate, and the connecting plate is welded to the disc body. The overall stability between the hollow cylinder and the gear body can be effectively improved by the reinforcing rib plate and the connecting plate.

[0009] Furthermore, a rubber sleeve is arranged on the periphery of one end of the adjusting screw away from the bearing.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The utility model is a gear with an external connection structure. A person can drive the displacement plate to slide along the guide groove by turning the adjusting screw, so as to adjust the distance between the fixed vertical plate and the displacement plate for pre-positioning. By inserting the fixed vertical plate and the displacement plate into the positioning groove, since the distance between the fixed vertical plate and the displacement plate is adjustable, the positioning structure can be inserted into positioning grooves of different widths, so as to facilitate pre-positioning between the disc body and the external connection disc. The gear has a structure for connecting with an external disc-shaped connecting piece, and does not have a pre-positioning structure with adjustable width when connected, so it is more convenient and quicker to connect with the external disc-shaped connecting piece.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-3 As shown, a gear with an external structure includes a hollow cylinder 1, a gear body 2 and a disc body 3, wherein the disc body 3 is arranged on the periphery of the top end of the hollow cylinder 1, a guide groove 7 is opened at the top of the disc body 3 near the edge, a fixed vertical plate 4 is welded at the top of the disc body 3 near the inner side of the guide groove 7, an adjusting screw 5 is arranged at one end of the fixed vertical plate 4 through a threaded groove, a bearing is arranged on the periphery of the end of the adjusting screw 5, a displacement plate 6 is connected to the end of the bearing, and the bottom end of the displacement plate 6 is located in the guide groove 7.

[0018] Wherein, the disk body 3 is also provided with connecting bolts 10 through screw holes near the edge.

[0019] In this embodiment, Figure 1-3 As shown, the disc body 3 is conveniently connected to the connecting disc on the external output shaft through the connecting bolts 10.

[0020] A reinforcing rib plate 8 is welded to the outside of the hollow cylinder 1 , one end of the reinforcing rib plate 8 is connected to the gear body 2 , and a connecting plate 9 is welded to the other end of the reinforcing rib plate 8 , and the connecting plate 9 is welded to the disc body 3 .

[0021] In this embodiment, Figure 1-3 As shown, the overall stability between the hollow cylinder 1 and the gear body 2 can be effectively improved by reinforcing the rib plate 8 and the connecting plate 9.

[0022] Wherein, a rubber sleeve is arranged on the periphery of one end of the adjusting screw 5 away from the bearing.

[0023] In this embodiment, Figure 1-3 As shown, the rubber sleeve can be used to effectively prevent slipping when personnel apply external force to the end of the adjusting screw 5.

[0024] It should be noted that the utility model is a gear with an external connection structure. When working, a connecting disc corresponding to the disc body 3 is provided on the output shaft of the external motor, and a threaded hole corresponding to the connecting bolt 10 is provided on the connecting disc, and a positioning groove corresponding to the fixed vertical plate 4 and the displacement plate 6 is provided. By rotating the adjusting screw 5, the displacement plate 6 is conveniently driven to slide along the guide groove 7, so as to adjust the distance between the fixed vertical plate 4 and the displacement plate 6 for pre-positioning. By inserting the fixed vertical plate 4 and the displacement plate 6 into the positioning groove, since the distance between the fixed vertical plate 4 and the displacement plate 6 is adjustable, the positioning structure can be inserted into the positioning grooves of different widths, so as to facilitate the pre-positioning between the disc body 3 and the external connecting disc, and then the connecting bolt 10 is matched with the threaded hole on the external connecting disc, so as to connect the disc body 3 and the external connecting disc, thereby connecting the gear to the output shaft of the external motor. The gear has a structure for connecting with an external disc-shaped connecting member, and does not have a pre-positioning structure that can adjust the width when connecting, so it is more convenient and quick when connecting with an external disc-shaped connecting member.
