In some embodiments of the present invention, as shown in fig. 1-8, the driving device 1 includes a rotation shaft 10, an adjustment block 80, an adjustment member 91, and a driving gear 30.

In some embodiments of the present invention, as shown in fig. 4, the adjustment block 80 has a fitting hole 83, and the rotation shaft 10 passes through the fitting hole 83 to coat the adjustment block 80 on the fitting hole 83, wherein the hole diameter of the fitting hole 83 is larger than the shaft diameter of the rotation shaft 10 so that the adjustment block 80 can move in the radial direction of the rotation shaft 10.

For convenience of description, as shown in fig. 6, the axial direction of the rotating shaft 10 is referred to as a first direction, the radial direction of the rotating shaft 10 is referred to as a second direction, since the adjusting member 91 is in threaded engagement with the second engaging hole 13, by rotating the adjusting member 91, the position of the adjusting member 91 along the second direction can be changed, and further, the position of the adjusting block 80 along the second direction can be changed, and since the adjusting block 80 is engaged with the driving gear 30 through the first engaging inclined surface 81 and the second engaging inclined surface 31, when the position of the adjusting block 80 along the second direction is changed, the position of the driving gear 30 along the first direction can be changed, and further, the axial position of the driving gear 30 can be adjusted, so that the engaging gap between the driving gear 30 and other gears along the axial direction of the rotating shaft 10 can be eliminated.

In some embodiments, as shown in fig. 6, the driving gear 30 is sleeved on the rotating shaft 10, a gap is formed between the driving gear 30 and the rotating shaft 10, the driving gear 30 drives the adjusting block 80 to rotate through friction force between the first matching inclined surface 81 and the second matching inclined surface 31, so that the adjusting piece 91 passes through the first matching hole 82 to be in threaded fit with the second matching hole 13, so that the adjusting block 80 and the rotating shaft 10 are connected together, and when the driving gear 30 rotates, the driving gear 30 drives the adjusting block 80 to rotate, the adjusting block 80 can drive the rotating shaft 10 to rotate, and the rotating shaft 10 can output rotating force outwards.

In some alternative embodiments of the present invention, as shown in fig. 4 and 6, an end of the adjusting member 91 away from the second fitting hole 13 is provided with a stop portion 911, and the stop portion 911 is in stop-fit with the outer circumferential surface of the adjusting block 80 to limit the position of the adjusting block 80 in the rotation radial direction, so as to avoid the adjusting member 91 from being disengaged from the adjusting block 80.

Specifically, when the adjuster 91 is rotated to move the stopper portion 911 in a direction approaching the second engagement hole 13, the stopper portion 911 presses the adjustment block 80 and moves the adjustment block 80, so that the first engagement hole 82 on the adjustment block 80 moves in a direction approaching the second engagement hole 13 in the radial direction of the rotation shaft 10, and the position of the adjustment block 80 in the radial direction of the rotation shaft 10 is adjusted, and when the position of the adjustment block 80 in the radial direction of the rotation shaft 10 is changed due to the engagement of the adjustment block 80 with the drive gear 30 via the first engagement inclined surface 81 and the second engagement inclined surface 31, the position of the drive gear 30 in the axial direction of the rotation shaft 10 is changed, so that the play between the drive gear 30 and other gears in the axial direction of the rotation shaft 10 is eliminated.

In some embodiments, as shown in fig. 6, the driving device 1 further includes an elastic abutment member 40, where the elastic abutment member 40 is connected to the driving gear 30 to apply a force to the driving gear 30 toward the adjustment block 80, the axial direction of the rotation shaft 10 extends in the left-right direction, the radial direction of the rotation shaft 10 extends in the up-down direction (it should be understood that the above-mentioned direction limitation is only for convenience of description of the drawings and does not limit the actual setting position and direction of the driving device 1), the driving gear 30 is located at the right end of the adjustment block 80, the elastic abutment member 40 is located at the right end of the driving gear 30, the first mating inclined surface 81 is parallel to the second mating inclined surface 31, the first mating inclined surface 81 extends from top to bottom to left, and the abutment portion 911 is located at the upper end of the adjustment block 80.

When the adjuster 91 is rotated to move the adjuster 91 downward, the abutment portion 911 pushes the adjusting block 80 to move downward, and at this time, the adjusting block 80 has a rightward force on the driving gear 30, so that the driving gear 30 can overcome the force of the elastic abutment 40 and move rightward, so as to adjust the position of the driving gear 30 in the left-right direction, and further eliminate the fit gap between the driving gear 30 and other gears in the left-right direction.

When the adjuster 91 is rotated to move the adjuster 91 upward, the drive gear 30 is moved leftward by the urging force of the elastic stopper 911, and the drive gear 30 pushes the adjustment block 80 upward until the stopper 911 is in stopper engagement with the outer peripheral surface of the adjustment block 80, that is, when the adjuster 91 is rotated to move the adjuster 91 upward, the elastic stopper 911 can push the drive gear 30 to move leftward to adjust the position of the drive gear 30 in the left-right direction, and further, the engagement gap between the drive gear 30 and other gears in the left-right direction can be eliminated.

As shown in fig. 3 and 4, the adjusting block 80 includes four outer peripheral surfaces, each of which is a flat surface, and the abutment portion 911 is in abutment engagement with one of the outer peripheral surfaces, so that when the position of the adjuster 91 in the radial direction of the rotary shaft 10 is adjusted, the position of the adjusting block 80 in the radial direction of the rotary shaft 10 can be changed,

In some alternative embodiments of the present invention, the adjusting member 91 is threadedly engaged with the first engaging hole 82, so that when the adjusting member 91 is rotated, the position of the adjusting block 80 along the radial direction of the rotating shaft 10 can be changed, and when the position of the adjusting block 80 along the radial direction of the rotating shaft 10 is changed, the position of the driving gear 30 along the axial direction of the rotating shaft 10 is changed, so that the engaging gap between the driving gear 30 and other gears along the axial direction of the rotating shaft 10 is eliminated, and stable transmission between the driving gear 30 and other gears is realized.

In some embodiments of the present invention, as shown in fig. 6, in the radial direction of the rotation shaft 10, the first engagement inclined surface 81 extends obliquely in a direction away from the adjusting member 91 and the driving gear 30, the second engagement inclined surface 31 is parallel to the first engagement inclined surface 81, and when the adjustment block 80 occurs in the radial direction of the rotation shaft 10, at the same position of the rotation shaft 10, the axial dimension of the first engagement inclined surface 81 changes, thereby changing the position of the driving gear 30 in the axial direction of the rotation shaft 10, so as to eliminate the clearance between the driving gear 30 and other gears in the axial direction of the rotation shaft 10, and realize stable transmission of the driving gear 30 and other gears.

When the included angle between the first matching inclined surface 81 and the radial direction of the rotating shaft is 5-60 degrees, the adjusting piece 91 has better adjusting efficiency and adjusting precision.

In some embodiments of the present invention, as shown in fig. 5 and 6, the rotation shaft 10 has a stopping protrusion 11, and the adjusting block 80 is clamped between the stopping protrusion 11 and the driving gear 30, so as to limit the position of the adjusting block 80 in the axial direction of the rotation shaft 10, so that the first matching inclined surface 81 is attached to the second matching inclined surface 31, and when the position of the adjusting block 80 along the radial direction of the rotation shaft 10 is changed, the position of the driving gear 30 along the axial direction of the rotation shaft 10 is changed, so that the position of the driving gear 30 in the axial direction of the rotation shaft 10 is smoothly adjusted, and gaps between the driving gear 30 and other gears in the axial direction are eliminated, so that the stability of transmission is improved.

When the gear portion 301 rotates, the gear portion 301 transmits torque to the rotating shaft 10 through the first bushing 92, and further drives the rotating shaft 10 to rotate, so that the rotating shaft 10 can output a rotating force outwards.

In some embodiments of the present invention, the driving device 1 further includes an elastic abutment member 40, where the elastic abutment member 40 is connected to the driving gear 30 to apply a force to the driving gear 30, and the force makes the driving gear 30 have a tendency to move toward the adjusting block 80, so that the first mating inclined surface 81 and the second mating inclined surface 31 are abutted, and thus when the driving gear 30 rotates, the adjusting block 80 can be driven to rotate, and when the adjusting block 80 rotates, the rotating shaft 10 can be driven to rotate, so that the rotating shaft 10 can output a rotating force outwards.

When the driving gear 30 is moved away from the adjusting block 80 due to the influence of an external force, the elastic stopper 40 can automatically drive the driving gear 30 to reset when the external force is eliminated, so that the gap between the driving gear 30 and the driving gear 63 is automatically eliminated, and the position of the driving gear 30 does not need to be manually adjusted.

In some alternative embodiments of the present invention, as shown in fig. 6, the elastic stopping portion 911 is formed as a spring, the outer peripheral wall of the rotating shaft 10 is provided with a fixing portion, and two ends of the elastic stopping portion 911 are respectively connected with the driving gear 30 and the fixing portion, so as to limit the position of the spring, so that the spring is in a compressed state, the spring can apply a force to the driving gear 30 towards the adjusting block 80, and further, the first matching inclined surface 81 and the second matching inclined surface 31 are matched, and further, when the position of the adjusting block 80 along the radial direction of the rotating shaft 10 is changed, the position of the driving gear 30 along the axial direction of the rotating shaft 10 is changed, so that the position of the driving gear 30 along the axial direction of the rotating shaft 10 is smoothly adjusted, gaps between the driving gear 30 and other gears in the axial direction are eliminated, and the stability of transmission is facilitated to be improved.
