[0022] The utility model proposes an embodiment of a transmission device mounting adjustment bracket, specifically, Figure 1 and Figure 2 As shown, it includes: a base frame 1, an adjustment mounting plate 9, a guide rail assembly, a radial adjustment assembly, and an axial adjustment assembly; wherein the base frame 1 is fixedly connected to the equipment frame, and the base frame 1 is formed with a first elongated adjustment slot 4 in the same radial direction as the transmission device 14 (that is, the extending direction of the hole is perpendicular to the axial direction of the transmission device), and a first fastening bolt 5 is passed through the first elongated adjustment slot 4 and connects the base frame 1 to the adjustment mounting plate 9;
[0023] The adjusting mounting plate 9 is formed with a second elongated adjusting slot 16 (corresponding to the position of the original fixing hole of the transmission device seat) in the same direction as the axial direction of the transmission device 14. The second fastening bolt 10 is passed through the second elongated adjusting slot 16 and connects the adjusting mounting plate 9 to the base of the transmission device 14.
[0024] The guide rail assembly is disposed between the adjustment mounting plate 9 and the base frame 1 so that the two can slide relative to each other, and the length direction of the guide rail assembly is in the same direction as the radial direction of the transmission device 14 (that is, parallel to the length direction of the first elongated adjustment slot 4);
[0025] The radial adjustment assembly is mounted on the base frame 1 and contacts the adjustment mounting plate 9 to adjust the radial position of the transmission device 14;
[0026] The axial adjustment assembly is mounted on the adjustment mounting plate 9 and contacts the base of the transmission device 14 to adjust the axial position of the transmission device 14 .
[0027] To elaborate, the radial adjustment assembly may specifically include: a first adjustment plate 8 is installed at one end of the base frame 1 close to the transmission follower, a first adjustment screw 6 is threaded on the first adjustment plate 8, and a first locking nut 7 is connected to the first adjustment screw 6, and the screw end of the first adjustment screw 6 is facing the adjustment mounting plate 9.
[0028] The axial adjustment assembly may specifically include: a second adjustment plate 13 is installed at one end of the adjustment mounting plate 9 close to the tail of the transmission device, a second adjustment screw 11 is screwed on the second adjustment plate 13, and a second locking nut 12 is connected to the second adjustment screw 11, and the screw end of the second adjustment screw 11 faces the base of the transmission device 14.
[0029] In order to ensure the stability of the axial adjustment process and reduce the probability of offset, preferably, the axial adjustment assembly has two adjacent sets, that is, the axial adjustment assembly includes two second adjustment plates 13, two second adjustment screws 11 and two second locking nuts 12.
[0030] In order to ensure that the two fastening bolts can move smoothly in their respective elongated adjustment slots, the width of the two elongated adjustment slots (relative to the length direction) is equal to the outer thread diameter of the corresponding fastening bolt + 2 mm.
[0031] Finally, it can be added that, combined with Figure 2 As shown, the guide rail assembly specifically includes: a first guide rail 2 and a second guide rail 3, and the base frame 1 and the adjustment mounting plate 9 are respectively connected to the corresponding parts of the two guide rails, that is, the upper surface of the base frame 1 is installed with partial components of the first guide rail 2 and the second guide rail 3 (such as a slider), and the lower surface of the adjustment mounting plate 9 is installed with partial components of the first guide rail 2 and the second guide rail 3 (such as a slide).
[0032] Based on the above embodiments, the working principle of the present invention is introduced as follows:
[0033] (1) Axial adjustment of the transmission device: When replacing the transmission device or its driving wheel, first return the second adjusting screw 11 to the appropriate position, install the transmission device slightly to the left, pre-tighten the four second fastening bolts 10, and push the transmission device to the right by rotating the two second adjusting screws 11 on the left and right. During the movement, continuously check the axial position relationship between the driving wheel and the driven wheel. When the preset standard is met, tighten the second fastening bolt 10 and the second locking nut 12, and the axial direction adjustment is completed. This adjustment is only performed when replacing the transmission device or the driving wheel, which solves the problem that the existing transmission device mounting bracket does not have an axial adjustment function and the axial position of the driving wheel is mainly guaranteed by the movement of the driving wheel on the output shaft of the transmission device, thereby eliminating the hidden dangers of equipment failure caused by the axial movement of the driving wheel.
[0034] (2) Radial adjustment of the transmission device (adjustment of belt / chain tension): When a new belt / chain needs to be replaced, loosen the first fastening bolt 5 that fixes the adjustment mounting plate 9, loosen the first locking nut 7, and retract the first adjusting screw 6 to the final position. Since the adjustment mounting plate 9 is installed on the base frame 1 through the guide rail assembly, the operator can easily push the adjustment mounting plate 9 to move toward the driven wheel ( Figure 1 To tighten the belt / chain, loosen the belt or chain and after the replacement is completed, screw in the first adjusting screw 6, push the adjusting mounting plate 9 to the right until the tension meets the requirements, tighten the first fastening bolt 5 and the first locking nut 7, and complete the replacement operation; when only the belt / chain needs to be tightened, loosen the first fastening bolt 5 and the first locking nut 7, screw in the first adjusting screw 6, push the adjusting mounting plate 9 to the right until the tension meets the requirements, tighten the first fastening bolt 5 and the first locking nut 7, and complete the tensioning operation. Figure 1 The left and right directions are moved by the guide rail assembly, eliminating problems such as jamming, shaking, and deflection during movement. Therefore, it is preferred to use a set of adjustment screws to complete the adjustment in this direction, which significantly improves work efficiency and results.
[0035] By adjusting the above two directions, the transmission device can be adjusted to an accurate and appropriate position, which can meet the requirements of the transmission belt (or chain) tension and the requirements of the transmission position deviation of the master and slave wheels.
[0036] In summary, the main design concept of the present invention is that it is composed of a base frame, an adjustment mounting plate, a guide rail assembly, a radial adjustment assembly, and an axial adjustment assembly, wherein the base frame is connected to the adjustment mounting plate, the adjustment mounting plate is connected to the base of the transmission device, the radial adjustment assembly is mounted on the base frame and adjusts the radial position of the transmission device by contacting the adjustment mounting plate, the axial adjustment assembly is mounted on the adjustment mounting plate and moves the adjustment mounting plate through the guide rail by contacting the base of the transmission device to adjust the axial position of the transmission device, and the guide rail assembly is arranged between the adjustment mounting plate and the base frame, realizing relative sliding between the two, thereby eliminating problems such as deflection during movement. The present invention can accurately position and firmly fix, solving the problem of large deviation in the transmission position of the master and slave wheels caused by the existing transmission device bracket, and can easily and quickly perform adjustment operations to meet the established installation requirements. It not only reduces the wear of the device, but also reduces the frequency of maintenance and saves maintenance costs.
