[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] Please see the attached Figures 1 to 4 As shown, an adjustable synchronous wheel in the embodiment of the present invention includes a wheel body 1, an axial hole is opened inside the wheel body 1, one end of the wheel body 1 is fixedly connected to a fixed retaining ring 5, and the other end of the wheel body 1 is fixedly connected to an end cover 2, and the outer end of the wheel body 1 is located between the end cover 2 and the fixed retaining ring 5 and is sleeved with an adjusting retaining ring 3. When in use, the synchronous belt is installed between the adjusting retaining ring 3 and the fixed retaining ring 5, and the adjusting retaining ring 3 can adjust the installation position. During the installation process, the installation position of the adjusting retaining ring 3 can be adjusted according to the actual width of the synchronous belt, so as to adapt to synchronous belts with different bandwidths. It has a wide range of applications and can also ensure that the synchronous belt can be accurately installed on the synchronous wheel, ensuring good meshing between the belt teeth and the wheel teeth.

[0027] Specifically, the adjusting retaining ring 3 includes two contact rings 31, and a fixing sleeve 32 is fixedly connected to the side of the contact ring 31 close to the end cover 2. The inner sides of the contact ring 31 and the fixing sleeve 32 are provided with teeth and grooves, and the teeth and grooves can be tightly engaged with the gear teeth on the surface of the wheel body 1. When in use, the contact ring 31 will contact the synchronous belt, and the fixing sleeve 32 mainly serves to increase the contact area with the wheel body 1 and improve the installation stability; the two groups of contact rings 31 and the fixing sleeve 32 are matched with the wheel body 1 through the teeth and grooves on their inner sides, and the fit is tight, the gap is small, and it is not easy to slip.

[0028] Among them, both ends of the fixing sleeve 32 are fixedly connected with connecting heads 33, and the upper and lower connecting heads 33 are fixedly connected by fastening bolts 34. The connecting heads 33, the fixing sleeve 32 and the contact ring 31 are integrally formed with high strength; during installation, the upper and lower groups of contact rings 31 and the fixing sleeve 32 are connected by fastening bolts 34 and clamped on the surface of the wheel body 1, and the installation stability is strong. When the position of the retaining ring 3 needs to be adjusted, the fastening bolts 34 can be loosened to release the upper and lower groups of contact rings 31 and the fixing sleeve 32 from the clamping state, and then they can be adjusted to the required position.

[0029] Example 2

[0030] See also Figures 3 and 4As shown, based on the first embodiment, the end cover 2 includes a cover plate 21, the center of which is provided with an axial hole identical to that of the wheel body 1, a clamping ring 22 is fixedly connected to the inner side of the cover plate 21, and a matching groove 6 is provided at one end of the wheel body 1 close to the end cover 2, and the clamping ring 22 is plugged into the matching groove 6;

[0031] The cover plate 21 is fixedly connected to the wheel body 1 via a plurality of mounting screws 23 , and the mounting screws 23 pass through the clamping ring 22 and the matching groove 6 .

[0032] The cover plate 2 can limit the installation position of the adjusting retaining ring 3, preventing the adjusting retaining ring 3 from being installed beyond the edge of the wheel body 1 during installation. It can also prevent the fastening bolts 34 from being fully tightened during installation, causing the adjusting retaining ring 3 to be loose, and the adjusting retaining ring 3 or even the synchronous belt to fall off the wheel body 1.

[0033] The end cover 2 is detachable. The end cover 2 can be removed by unscrewing the multiple mounting screws 23 of the end cover 2, which is convenient for subsequent maintenance. The provided clamping ring 22 and the matching groove 6 can improve the connection strength.

[0034] In addition, a plurality of sleeves 24 are arranged at intervals on the outer end of the cover plate 21, and a plurality of guide rods 35 are fixedly connected to the side of the contact ring 31 facing the end cover 2. The guide rods 35 correspond to the sleeves 24 one by one and are slidably inserted into the interior of the sleeves 24. The arrangement of the guide rods 25 and the sleeves 24 facilitates positioning when installing the contact ring 31, and can also play a limiting role when adjusting the position of the adjusting retaining ring 3, further ensuring that the adjusting retaining ring 3 will not deflect during adjustment. At the same time, due to the constraints of the guide rods 35 and the sleeves 24, after loosening the fastening bolts 34, the contact ring 31 and the fixing sleeve 32 located on the lower side are not easy to fall off, thereby facilitating adjustment.

[0035] It should be noted that the guide rod 35 can be fully extended into the sleeve 24 , and after the guide rod 35 is fully inserted into the sleeve 24 , the fixing sleeve 32 can contact the cover plate 21 , thereby reaching the maximum adjustment position.

[0036] Example 3

[0037] See also Figure 3 and Figure 5 As shown, based on the embodiment 1, a top screw type sleeve 4 is fixed to one end of the wheel body 1 close to the fixed retaining ring 5, and the top screw type sleeve 4 includes a sleeve body 1 41, an axial hole 1 42 is opened inside the sleeve body 1 41, and a top screw hole 43 is opened at the upper end of the sleeve body 1 41;

[0038] When the adjustable synchronous wheel is installed on the shaft, the synchronous wheel and the shaft are fixed by installing a top screw through the top screw hole 43 opened at the upper end of the sleeve body 41. The top screw hole 43 is not opened on the wheel body 1 and will not interfere with the adjustment of the regulating ring 3. Among them, the shaft hole 42 and the shaft hole of the wheel body 1 can adopt flat key shaft holes.

[0039] In order to obtain a greater torque and meet the needs of use in more occasions, this embodiment also provides another implementation method. Specifically, a clamping sleeve 7 is fixed to one end of the wheel body 1 close to the fixed retaining ring 5. The clamping sleeve 7 includes a second sleeve body 701. The interior of the second sleeve body 701 is provided with a second shaft hole 702. One side of the second sleeve body 701 is provided with a through groove passing through the second shaft hole 702 and is connected with a clamping bolt 703. When the clamping sleeve 7 is in use, the second sleeve body 701 is tightly clamped on the outer end of the shaft by tightening the clamping bolt 703. This method does not require additional keyway or flat processing on the shaft, will not reduce the strength of the shaft, and has a large clamping torque that can meet most usage occasions.

[0040] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
