Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0019] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0020] Please refer to the following: Figs. 1 to 3 As shown, Fig. 1 A three-dimensional structural diagram of the novel worm gear reducer device 100 at a first angle; Fig. 2 A three-dimensional structural diagram of the novel worm gear reducer device 100 from a second angle; Fig. 3 This is a schematic diagram of the structure of the new worm gear reducer device 100 with the adjusting block 701 in the separated state.
[0021] This utility model provides the following technical solution: A novel worm gear reducer device 100 includes a housing 20, a worm gear 30 rotatably disposed inside the housing 20, a motor 40 fixedly disposed on one side of the housing 20, a worm 50 connected to the output end of the motor 40, the worm 50 being located inside the housing 20 and meshing with the worm gear 30, an adjusting block 701 rotatably connected to the end of the worm 50 away from the motor 40, an adjusting hole 201 being opened on the other side of the housing 20, the adjusting block 701 being located inside the adjusting hole 201, the adjusting block 701 having a mounting piece 702 abutting against the outside of the housing 20, and an adjusting member 80 movably connected to the bottom of the housing 20, the adjusting member 80 extending into the adjusting hole 201 to abut against the bottom of the adjusting block 701.
[0022] In the novel worm gear reducer device 100 provided in this embodiment, the worm 50 is driven to rotate by a motor 40 at one end, and the other end of the worm 50 is supported by an adjusting block 701. When the worm 50 rotates, it meshes with and drives the worm wheel 30 to rotate, thereby realizing the operation of the reducer device. During the assembly of the worm wheel 30 and the worm 50, if it is necessary to adjust the meshing tightness between the worm wheel 30 and the worm 50, and the meshing is too loose, the adjusting member 80 is manually operated to lift the adjusting block 701 within the adjusting hole 201. This causes the adjusting block 701 to raise the worm 50 to a higher position, allowing it to deeply engage with the worm wheel 30, thereby tightening the meshing between the worm wheel 30 and the worm 50. If the meshing between the worm gear 30 and the worm 50 is too tight, the adjusting member 80 is manually lowered within the adjusting hole 201. This reduces the lifting height of the adjusting block 701, allowing it to descend within the adjusting hole 201. As the adjusting block 701 descends, it supports the worm 50, disengaging it from the worm gear 30 and thus loosening the meshing between them. After adjusting the meshing tightness, the mounting plate 702 is fixed to the outer side of the housing 20 using screws to maintain the adjusted meshing force between the worm gear 30 and the worm 50. In this utility model, when the worm gear 30 and the worm 50 are assembled and meshed, the user can operate the adjusting component 80 to adjust the meshing tightness between the worm gear 30 and the worm 50, and then fix and maintain the meshing state between the worm gear 30 and the worm 50, which has the advantages of being practical and convenient.
[0023] In some embodiments, a deep groove ball bearing 60 is installed at the end of the worm gear 50 away from the motor 40, and the deep groove ball bearing 60 is fixed in the adjusting block 701.
[0024] In specific implementation: When the motor 40 drives the worm 50 to rotate at one end, the other end of the worm 50 is supported by a deep groove ball bearing 60 fixed in the adjusting block 701. This arrangement allows the adjusting block 701 to support the end of the worm 50 via the deep groove ball bearing 60 fixed therein.
[0025] In some embodiments, the adjusting member 80 includes a threaded rod 801 and a nut 802. The threaded rod 801 is threaded to the bottom of the housing 20 and extends into the adjusting hole 201 to abut against the bottom of the adjusting block 701. The height of the adjusting block 701 is less than the height of the adjusting hole 201. The nut 802 is threaded to the threaded rod 801 and abuts against the outside of the bottom of the housing 20.
[0026] In practice: When the user operates the adjusting component 80 to adjust the meshing tightness between the worm gear 30 and the worm 50, the user loosens the nut 802 on the threaded rod 801 so that the nut 802 does not abut against the outside of the bottom of the housing 20. Then, the user manually rotates the threaded rod 801 clockwise or counterclockwise on the housing 20 so that the threaded rod 801 rises in the adjusting hole 201 to lift the adjusting block 701 or descends in the adjusting hole 201 to support the descending of the adjusting block 701. Thus, when the adjusting block 701 rises, it drives the worm 50. When the worm gear 30 is raised to a higher position and deeply engaged with the worm wheel 30, or when the adjusting block 701 descends, it supports the worm 50 to descend and disengage from the worm wheel 30, thereby adjusting the meshing tightness between the worm wheel 30 and the worm 50. After adjusting the meshing tightness between the worm wheel 30 and the worm 50, the nut 802 on the threaded rod 801 is tightened so that the nut 802 abuts against the bottom outside of the housing 20, thereby maintaining and fixing the height of the adjusting block 701 supported by the threaded rod 801, and thus maintaining and fixing the adjusted meshing tightness between the worm wheel 30 and the worm 50. The height of the adjusting block 701 is less than the height of the adjusting hole 201, so that the adjusting block 701 has room for vertical displacement within the adjusting hole 201. This design allows the user to conveniently adjust the meshing tightness between the worm wheel 30 and the worm 50 during assembly using the adjusting component 80.
[0027] In some embodiments, a mounting bracket 10 is also included, and a housing 20 is disposed on the mounting bracket 10.
[0028] In practical implementation: the housing 20 is mounted on the mounting bracket 10, so that the housing 20 can be installed on the equipment via the mounting bracket 10. The mounting bracket 10 and the equipment can be fixed together with bolts. With this arrangement, the novel worm gear reducer device 100 can be installed on the equipment for use.
[0029] In some embodiments, the mounting bracket 10 and the housing 20 are integrally formed.
[0030] In practice: the mounting bracket 10 and the housing 20 are integrally formed, thus improving the connection between the mounting bracket 10 and the housing 20. This design enhances the stability between the mounting bracket 10 and the housing 20.
[0031] In some embodiments, the adjustment block 701 and the mounting plate 702 are integrally formed.
[0032] In practice: the adjusting block 701 and the mounting piece 702 are integrally formed, thus improving the connection between the adjusting block 701 and the mounting piece 702. This design enhances the stability between the adjusting block 701 and the mounting piece 702.
