The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.
Referring to fig. 1, fig. 1 is a cross-sectional view of a reduction gearbox and a concentricity calibration mechanism at a first viewing angle according to an embodiment of the present invention, and in an embodiment, the concentricity calibration mechanism includes: the buffer sleeve member 100 and the transfer sleeve member 200 are provided, the buffer sleeve member 100 is used for being sleeved in the rotating end 110 of the reduction gearbox, the transfer sleeve member 200 is sleeved inside the buffer sleeve member 100, the transfer sleeve member 200 is abutted to one set of surface of the buffer sleeve member 100 in a fit manner, the other set of surface of the buffer sleeve member 100 is abutted to the rotating end 110 of the reduction gearbox in a fit manner, and the transfer sleeve member 200 is provided with a connecting part 210 which is used for being in rotating fit with the screw.
When the concentric correction mechanism is used, firstly, the sleeved size of the buffer sleeve member 100 and the sleeved size of the transfer sleeve member 200 are determined according to the opening size of the rotating end 110 of the reduction gearbox and the size of the required connecting screw rod. Namely, the buffering kit 100 and the transfer kit 200 are both installed at the rotating end 110 of the reduction box and then can be installed and matched with the preset screw. In addition, the positions of the buffering sleeve member 100 and the transfer sleeve member 200 in the rotation end 110 of the speed reducer are determined according to the corresponding position of the output shaft of the driving assembly 300 of the speed reducer on the rotation end 110, so that the screw and the output shaft of the driving assembly 300 can concentrically rotate after the screw and the transfer sleeve member 200 are installed and matched. The other set of surface of the buffer kit 100 is abutted against the rotating end 110 of the reduction box by the abutting of the adapter kit 200 and one set of surface of the buffer kit 100, so that after the screw and the adapter kit 200 are installed and matched, the screw can rotate synchronously along with the rotation end 110 of the reduction box. When the screw rod is deformed, the stress change occurs at the position of the adapter sleeve 200 corresponding to the screw rod, and at this time, the buffer sleeve 100 is deformed according to the stress of the part. Namely, the concentric correction mechanism realizes the re-correction of the deformed screw rod through the adapter sleeve 200 and the buffer sleeve 100, ensures that the deformed screw rod can still concentrically rotate with the driving component 300, and improves the matching use effect of the screw rod and the reduction gearbox.
In one embodiment, the buffer assembly is a rubber sleeve or a silicone sleeve. The adapter sleeve 200 is an adapter spline or a gear sleeve. The connecting portion 210 is formed with engaging serrations or protrusions for engaging the screw. (e.g., by a projection engaging a groove in the screw)
In one embodiment, it should be noted that, when the conventional reduction gearbox is assembled with the screw, after the screw deforms, in order to ensure the installation and matching of the screw and the reduction gearbox, an adapter is additionally installed by a worker; namely, one end of the adapter can be connected with the deformed screw, and the other end of the adapter is connected with the rotating end 110 of the reduction gearbox. The mode leads to the increase of the integral connection length of the reduction gearbox and the screw rod, thereby influencing the installation effect of the reduction gearbox and the screw rod. The reduction gearbox can correct deformation of the deformed screw rod through the concentric correction mechanism, so that an adapter or other auxiliary components are not required to be additionally arranged.
As shown in fig. 1 to 3, in an embodiment, a reduction gearbox includes a concentric correction mechanism, and further includes a driving assembly 300, a transmission mechanism 400 and an installation body 500, the driving assembly 300 and the transmission mechanism 400 are both installed in the installation body 500, an output shaft of the driving assembly 300 is connected to the transmission mechanism 400, the transmission mechanism 400 is provided with a rotation end 110 for rotationally matching with a screw, the concentric correction mechanism is installed in the rotation end 110, and the installation body 500 is provided with an adaptation port for installation matching of the rotation end 110 and the screw.

Meanwhile, the concentric correction mechanism abuts against one set of surface of the buffer sleeve member 100 through the joint sleeve member 200 and abuts against the rotating end 110 of the reduction box through the other set of surface of the buffer sleeve member 100, so that after the screw and the joint sleeve member 200 are installed and matched, the screw can rotate synchronously along with the rotation end 110 of the reduction box. When the screw rod is deformed, the stress change occurs at the position of the adapter sleeve 200 corresponding to the screw rod, and at this time, the buffer sleeve 100 is deformed according to the stress of the part. Namely, the concentric correction mechanism realizes the re-correction of the deformed screw rod through the adapter sleeve 200 and the buffer sleeve 100, ensures that the deformed screw rod can still concentrically rotate with the driving component 300, and improves the matching use effect of the screw rod and the reduction gearbox.
