Description

Technical Field

[0001] This utility model relates to the field of transmission equipment technology, and in particular to a pulley seat that is easy to adjust and install. Background Technology

[0002] With the continuous improvement of industrial automation, transmission devices in mechanical equipment are also developing towards greater efficiency and precision. Belt drives, as a common mechanical transmission method, are widely used in various equipment.

[0003] However, traditional belt drive systems have certain limitations, especially in terms of pulley spacing adjustment. Traditional pulley installation methods often employ a fixed design, meaning that once the distance between the pulleys is determined, it is difficult to adjust. This makes it difficult to flexibly adjust the tension of the timing belt according to actual working conditions. When the timing belt is too loose, slippage may occur, affecting transmission efficiency; while being too tight will increase the load on the pulley bearings, accelerating the wear of the timing belt and other related components, and shortening their service life. Furthermore, due to thermal expansion during mechanical operation or natural relaxation after prolonged use, the tension of the timing belt will also change. Therefore, regularly checking and adjusting the tension of the timing belt is crucial to ensuring the stability and reliability of the transmission system.

[0004] Therefore, in view of the above-mentioned technical problems, this application aims to provide a pulley seat that facilitates fine adjustment of the pulley position, thereby effectively controlling the tension of the synchronous belt and improving the performance and reliability of the transmission system. Utility Model Content

[0005] This invention proposes a pulley seat that is easy to adjust and install, solving the aforementioned problems existing in the use of the prior art.

[0006] The technical solution of this utility model is implemented as follows: A pulley seat that is easy to adjust and install includes a seat body, the seat body including a base plate and side plates fixedly connected to the base plate. Two side plates are symmetrically arranged on the left and right sides. The seat body provides a driving pulley and a driven pulley between the two side plates. The driving pulley is located in front of the driven pulley. Each of the two side plates has a strip-shaped mounting groove with a rearward opening on one side facing each other. Each of the two side plates has a stop seat detachably connected to the rear opening of the strip-shaped mounting groove. A screw is rotatably connected to the stop seat. A rotating shaft is rotatably sleeved inside the driven pulley. The left and right ends of the rotating shaft extend into the strip-shaped mounting groove and are threadedly connected to the screw.

[0007] Preferably, the left and right ends of the rotating shaft are provided with planar grooves on the upper and lower sides. The planar grooves are used to fit against the upper and lower sides of the strip mounting groove, and the strip mounting groove can only allow the rotating shaft to slide back and forth within it.

[0008] Preferably, the side plate has a limiting step at the rear opening of the strip mounting groove, the stop includes a support platform that abuts against the limiting step, the side plate has rearward-facing slots on both the upper and lower sides of the strip mounting groove, and the stop also includes a locking block that is inserted into the slot.

[0009] Preferably, the stop is interference-fitted into the strip mounting groove, and the side plate has notches extending through the rear end of the strip mounting groove on both sides.

[0010] Preferably, the side plate is provided with screws for fixing the stop.

[0011] Preferably, a support plate is provided between the driving pulley and the driven pulley, and the left and right ends of the support plate are respectively fixedly connected to the two side plates.

[0012] Preferably, the drive pulley has a through hole in the middle, and both side plates have openings corresponding to the through hole. A support bearing corresponding to the opening is fixedly connected to the outer side of one of the side plates.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model features a strip-shaped mounting groove on the side plate, with the driven pulley's shaft threadedly connected to a screw. This allows users to easily move the driven pulley back and forth by rotating the screw, thereby precisely adjusting the tension of the timing belt. This design not only improves the ease of adjustment but also ensures that the timing belt always maintains its optimal working condition. Furthermore, the screw is rotatably connected to a stop seat, which is detachably attached to the side plate, facilitating installation and disassembly.

[0015] 2. Because the shaft of the passive pulley can slide back and forth in the strip mounting groove, and is in contact with the upper and lower sides of the mounting groove through the flat groove, the stability of the shaft during movement is ensured, and wear caused by shaking is avoided.

Detailed Implementation

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example:

[0025] like Figures 1 to 5 As shown, this utility model discloses a pulley seat that is easy to adjust and install, including a seat body 1. The seat body 1 includes a base plate 11 and two side plates 12 fixedly connected to the base plate 11. The side plates 12 are arranged symmetrically on the left and right sides. The base plate 11 and the side plates 12 are integrally formed structures, as shown in the figure. Figure 5 As shown, a fixing plate 8 is fixedly connected to the lower side of the base plate 11. The fixing plate 8 can be used to install this utility model on the equipment that needs to be installed. In this utility model, the base 1 is provided with a driving pulley 2 and a driven pulley 30 between the two side plates 12. The driving pulley 2 is located in front of the driven pulley 30, and as... Figure 4As shown, the synchronous belt is installed on the driving pulley 2 and the driven pulley 30. In order to adjust the position of the driven pulley 30 and thus adjust the tension of the synchronous belt, the present invention provides a rearward-facing strip-shaped mounting groove 121 on each of the two side plates 12. Furthermore, a stop 4 is detachably connected to the rear opening of the strip-shaped mounting groove 121 on each of the two side plates 12. A screw 5 is rotatably connected to the stop 4. A rotating shaft 31 is rotatably sleeved inside the driven pulley 30. A bearing 32 is assembled between the rotating shaft 31 and the driven pulley 30. The left and right ends of the rotating shaft 31 extend into the strip-shaped mounting groove 121 of the left and right side plates 12, respectively. The head of the screw 5 is located at the rear end of the stop 4. The rod of the screw 5 extends into the strip-shaped mounting groove 121 and passes through the rotating shaft 31. Specifically, the rod of the screw 5 is threadedly connected to the rotating shaft 31.

[0026] This utility model, by setting a strip-shaped mounting groove 121 on the side plate 12 and threading the rotating shaft 31 of the driven pulley 30 to the screw 5, allows the user to easily move the driven pulley 30 back and forth by rotating the screw 5, thereby precisely adjusting the tension of the synchronous belt. This design not only improves the convenience of adjustment, but also ensures that the synchronous belt always maintains the best working condition. In addition, the screw 5 is rotatably connected to the stop 4, which is detachably connected to the side plate 12, thus facilitating installation and disassembly. It should be noted that during adjustment, it is best to rotate both screws 5 at the same time, or after removing the synchronous belt, remove the stop, screw 5, rotating shaft 31 and driven pulley 30 together from the base 1, adjust the rotating shaft 31 to the appropriate position relative to the screw 5, and then install it back onto the base 1.

[0027] Furthermore, both ends of the rotating shaft 31 have flat grooves 311 on their upper and lower sides. The flat grooves 311 are used to fit against the upper and lower sides of the strip mounting groove 121. The strip mounting groove 121 can only allow the rotating shaft 31 to slide back and forth within it. This structure improves the stability of the rotating shaft 31 mounting structure.

[0028] In this invention, the side plate 12 has a limiting step 122 at the rear opening of the strip mounting groove 121. The stop 4 includes a support platform 41 that abuts against the limiting step 122. The support platform 41 and the limiting step 122 are used to limit the forward movement of the stop 4. In addition, the side plate 12 has rearward-facing latches 123 on both the upper and lower sides of the strip mounting groove 121. The stop 4 also includes a locking block 42 that inserts into the latches 123. The latches 123 and the locking block 42 are used to limit the left and right movement of the stop 4. The stop 4 is interference-fitted into the strip mounting groove 121. The side plate 12 has notches 124 extending through the rear of the strip mounting groove 121 on both sides. When the user needs to remove the stop 4, he / she can use pliers to clamp the rear of the stop 4 from both sides at the notches 124 and then pull it out.

[0029] Furthermore, to more securely fix the stop 4 to the side plate 12, screws 6 for fixing the stop 4 can be provided on the side plate 12.

[0030] In this utility model, a support plate 13 is provided between the driving pulley 2 and the driven pulley 30. The left and right ends of the support plate 13 are respectively fixedly connected to two side plates 12, such as... Figure 4 As shown, the support plate 13 is used to support the synchronous belt.

[0031] In this utility model, a shaft hole 21 is provided through the middle of the drive pulley, and two side plates 12 are provided with through holes 125 corresponding to the shaft hole 21. A support bearing 7 corresponding to the through hole 125 is fixedly connected to the outer side of one of the side plates 12. In use, the output shaft of the motor or the shaft driven by the motor passes through the through hole 125 and is keyed into the shaft hole 21 of the drive pulley, and extends into the support bearing 7. In this way, the position of the drive pulley 2 is fixed, and the motor drives the drive pulley 2 to rotate, thereby driving the driven pulley 30 and the synchronous belt.
