Description

Technical Field

[0001] The utility model relates to the technical field of transmission component adjustment, in particular to a gear transmission adjustment device. Background Art

[0002] Gear transmission is mainly the tooth-groove meshing transmission between two gears, and among the forms of driving gears to rotate, belt transmission has the simplest structure. However, when using belt transmission, due to the rotation wear of the belt, the gap caused by wear increases after a period of use, the belt transmission is easy to slip, and the transmission efficiency is low. If the belt is directly tightened to adjust the tightness without replacing the belt, either the position of the power device or the position of the driving tooth must be adjusted. If the position of the power device is adjusted, it is more troublesome, the adjustment frequency is higher, and the labor intensity is high. Since the position of the driven gear does not move, if the position of the driving tooth is adjusted, the meshing gap between the two meshing gears will change, so that the meshing is not in place and the transmission is affected.

[0005] With the above structure, an electric cylinder is provided to facilitate driving the connection plate to rotate, so as to synchronously drive the transmission wheel and the transmission tooth to rotate, and then the translation component adjusts the gap between the output end of the power motor and the transmission tooth, that is, the tightness of the tensioning adjustment belt is adjusted. After the tension is adjusted, the electric cylinder is started again to drive the transmission tooth to move back to the position of the driven tooth. Since the tooth shape and the module ratio remain unchanged, the tooth grooves are adaptively re-engaged and connected according to the tooth spacing after tensioning, and then the electric cylinder is closed to achieve meshing connection and re-positioning. The structure is simple and the operation is convenient.

[0006] For ease of installation, preferably, a driving wheel is provided at the output end of the power motor, and the driving wheel is connected to the transmission wheel by a belt drive.

[0019] Depend on Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model includes a base 1, a power motor 2 arranged on one side of the base 1, and a translation assembly arranged on the other side of the base 1 and connected to the output end of the power motor 2. An electric cylinder 10 is also provided on the base 1, and a connecting plate 20 is hinged at the output end of the electric cylinder 10. One end of the connecting plate 20 is connected to the translation assembly, and the other end is provided with a transmission wheel 3 connected to the output end of the power motor 2 by belt transmission, and a transmission tooth 30 is provided on the transmission wheel 3.

[0020] Specifically, the translation assembly includes a support plate 11 fixed on the base 1, a transmission motor 12 is provided on the support plate 11, an output end of the transmission motor 12 is provided with a rotating shaft 13 passing through the support plate 11, a threaded section 131 is provided on the rotating shaft 13, a connecting sleeve 14 is threadedly provided on the threaded section 131, the connecting sleeve 14 is connected to one end of a connecting block 15, the other end of the connecting block 15 is fixed with a connecting shaft 21 passing through one end of a connecting plate 20, a first bearing 211 is sleeved on the connecting shaft 21, an installation sleeve 22 is sleeved on the outer side of the first bearing 211, and the outer side of the installation sleeve 22 is sleeved and connected to the connecting plate 20.

[0021] A driving wheel 31 is provided at the output end of the power motor 2 , and the driving wheel 31 is connected to the transmission wheel 3 by a belt transmission.

[0022] A connecting rod 23 is passed through the other end of the connecting plate 20 , a second bearing 24 is sleeved on the passing end of the connecting rod 23 , a transmission wheel 3 is sleeved on one end of the outer side of the second bearing 24 , and a transmission gear 30 is sleeved on the other end.

[0023] A connecting frame 25 is hingedly provided on the connecting plate 20 , one end of the connecting frame 25 is hingedly connected to one end of the damper 4 , and the other end of the damper 4 is hingedly connected to the outer side of the connecting sleeve 14 .

[0024] The operating principle of the utility model is as follows:

[0025] like Figures 1 to 4 As shown, when in use, if the transmission belt is loose, first start the electric cylinder 10 to drive the connecting plate 20 to rotate counterclockwise with the center of the mounting sleeve 22 as the center of the circle, so that the transmission tooth 30 moves out of the meshing position, then turn off the electric cylinder 10, and then start the transmission motor 12 to drive the rotating shaft 13 to rotate, and the threaded connecting sleeve 14 moves horizontally to the right ( Figure 1 ), synchronously driving the transmission gear 30 and the transmission wheel 3 to move right together until the tension of the transmission belt is adjusted to the right position, at which time the transmission motor 12 is turned off.

[0026] Subsequently, the electric cylinder 10 is started again to drive the connecting plate 20 to rotate in the counterclockwise direction with the center of the mounting sleeve 22 as the center of the circle, so that the transmission tooth 30 moves back to the driven tooth (not shown). Due to the generated meshing misalignment gap, but the tooth shape and the module ratio remain unchanged, according to the tensioned tooth spacing, when the tooth groove is extended, the electric cylinder 10 should drive the transmission tooth 30 to move slowly during this period so that the tooth grooves can be adaptively re-engaged and connected. When the meshing is in place, the electric cylinder 10 is closed to achieve the repositioning of the meshing connection.

[0027] It should be noted that, if the electric cylinder 10 fails, the connecting plate 20 is supported by the damper 4 which is also hingedly connected to the connecting plate. When in use, the transmission motor 12 is first adjusted to slow down, and then the transmission motor 12 is started to drive the rotating shaft 13 to rotate, and the threaded connecting sleeve 14 is slowly moved to the right horizontally. At this time, the transmission tooth 30 which is still in the meshing state synchronously moves to the right along the tooth surface of the driven tooth, and at the same time maintains the rotational state of meshing transmission with the driven tooth. The damper 4 plays a role of supporting and buffering the translational resistance in this process. When the tension of the transmission belt is adjusted to the right, the transmission motor 12 is turned off at this time, and the transmission tooth 30 is also synchronously adaptively adjusted to the right without being out of the meshing state.

[0028] In this embodiment, in order to facilitate operation and adjustment control, the electric cylinder 10, the transmission motor 12 and the power motor 2 are preferably connected to the PLC controller. Since only the use of the PLC controller is involved, the connection between the relevant components and the PLC controller will not be repeated here.
