[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1~Figure 2 , the embodiments of the present utility model include:

[0020] like Figure 1 and Figure 2 The connection and fixing structure of the gearbox and the motor shown includes: a gearbox 4, a motor 2, a motor fixing rod 10 and an adjusting screw 1. The motor 2 is arranged on one side of the gearbox 4, and the rotating shaft of the motor 2 can be connected to the input end of the gearbox 4 through a coupling.

[0021] In this embodiment, a connecting seat 5 is provided at the end of the motor 2, and a second screw 3 connected to the gear box 1 is provided on the connecting seat 5 to connect and fix the end of the motor 2 housing to the gear box 1 housing. The coupling is located in the connecting seat 5 for safety protection. Figure 1 As shown, the motor 2 is relatively long and heavy, and fixing it only by the connecting seat 5 is obviously not stable enough.

[0022] The motor fixing rod 10 is set at the bottom or top of the motor 2. In this embodiment, the length direction of the motor fixing rod 10 is perpendicular to the axial direction of the motor 2, so that the motor fixing rod 10 extends horizontally along the width of the motor 2 housing.

[0023] The side of the motor fixing rod 10 that contacts the motor 2 is provided with a mating surface 13 that fits with the housing of the motor 2 to ensure a tight fit. The motor fixing rod 10 is provided with a first screw 14 connected to the motor 2, which facilitates assembly and prevents the motor fixing rod 10 from falling off.

[0024] like Figure 1 As shown, first fisheye joints 6 are provided at both ends of the motor fixing rod 10. The first fisheye joints 6 are provided with first pins 9 connected to the ends of the motor fixing rod 10. This allows for installation of the first fisheye joints 6 without affecting the swing adjustment of the first fisheye joints 6. Second fisheye joints 7 are provided on both sides of the gearbox 4 corresponding to the first fisheye joints 6. The second fisheye joints 7 are provided with second pins 8 connected to the gearbox 4 without affecting the swing adjustment of the second fisheye joints 7.

[0025] In this embodiment, the motor fixing rod 10 is fixed to the bottom of the motor 2, and the adjusting screw 1 is arranged between the corresponding first fisheye joint 6 and the second fisheye joint 7. The first fisheye joint 6 and the motor fixing rod 10 are supported by the adjusting screw 1, thereby supporting the bottom of the motor 2 and improving the connection stability between the motor 2 and the gear box.

[0026] A left-handed threaded hole is provided in the first fisheye joint 6, and a first external thread 11 corresponding to the left-handed threaded hole is provided at one end of the adjusting screw rod 1 pointing to the first fisheye joint 6. A right-handed threaded hole is provided in the second fisheye joint 7, and a second external thread 12 corresponding to the right-handed threaded hole is provided at one end of the adjusting screw rod 1 pointing to the second fisheye joint 7. By rotating the adjusting screw rod 1, the distance between the first fisheye joint 6 and the second fisheye joint 7 can be changed, thereby improving the adaptability to motors of different models. For motors of different models, after the motor fixing rod 10 is installed at the bottom of the motor, the position of the motor fixing rod 10 changes, especially the change in the position height of the motor fixing rod 10 and the change in the axial position along the motor, which requires changing the distance and angle between the first fisheye joint 6 and the second fisheye joint 7.

[0027] like Figure 2 As shown, the first fisheye joint 6 and the second fisheye joint 7 are not at the same height position, so that the adjusting screw rod 1 is tilted between the first fisheye joint 6 and the second fisheye joint 7 to provide oblique support for the bottom of the motor 2, as shown in FIG. Figure 1 As shown, the adjusting screw 1, the motor 2 and the gear box 4 form a right triangle structure with high stability. In addition, the inclined adjusting screw 1 reduces the space occupied by the motor, which is beneficial to improving the utilization rate of the space under the motor.

[0028] In summary, the utility model points out a connection and fixing structure between a gearbox and a motor, in which the first fisheye joint, the second fisheye joint, and the adjusting screw can all be made of procureable standard parts, which reduces costs, facilitates installation and adjustment, and improves adaptability to motor replacement and gearbox fine-tuning.

[0029] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
