[0033] The following will be combined with the 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.

[0034] The following is combined with Figures 1 to 5 This application is described in further detail.

[0035] The embodiment of the present application discloses a filter cloth transmission gearbox for a filter press.

[0036] Reference Figures 1 to 5 , a filter cloth transmission gearbox for a filter press, comprising:

[0037] The box body 1 is rectangular in shape as a whole and includes a first chamber and a second chamber.

[0038] One end of the driving gear 2 is provided with a driving stepped shaft 3 as an integrated structure. A through hole A4 is formed through the driving gear 2 and the driving stepped shaft 3. The through hole A4 is a spline hole. The opening of the through hole A4 facilitates the connection of an external power source, such as a spline shaft, to drive the driving gear 2 to rotate. A spherical bearing 5 is provided on the driving stepped shaft 3. The driving gear 2 is rotatably arranged in the first chamber via the spherical bearing 5. A first end cap 6 is provided at one end of the first chamber, and a hole retaining ring 7 is provided at the other end of the first chamber. Two hole retaining rings 7 are provided at intervals, and a sealing ring 8 is provided between the two hole retaining rings 7. The provision of the sealing ring 8 can play a sealing and protective role to prevent the entry of dust and impurities.

[0039] The other end of the inner ring of the spherical bearing 5 is against the shoulder on the active stepped shaft 3, the other end of the outer ring of the spherical bearing 5 is against the box body 1, one end of the inner ring of the spherical bearing 5 is against the shaft retaining ring 9, and the shaft retaining ring 9 is arranged on the active stepped shaft 3. A spacer sleeve A10 is arranged between the outer ring of the spherical bearing 5 and the first end cover 6. The spherical bearing 5 is securely installed to prevent the spherical bearing 5 from being separated from the active stepped shaft 3.

[0040] A through opening is provided on the first end cover 6 , and this structural arrangement facilitates the penetration of the active stepped shaft 3 or other connecting shafts (such as a spline shaft).

[0041] The driven gear 11 is provided with a driven stepped shaft 12 in an integrated structure at both ends, and a through hole B13 is provided through the driven gear 11 and the driven stepped shaft 12. The through hole B13 is an axial hole and is provided with a keyway 14. The setting of the through hole B13 facilitates connection with the outside and output of power, such as connection with the output shaft through a key.

[0042] The driven gear 11 is rotatably mounted within the second chamber at both ends via deep groove ball bearings 15. A second end cap 16 is provided at one end of the second chamber, and a spacer sleeve B17 is provided at the other end. The opposing inner ends of the two deep groove ball bearings 15 abut against the driven stepped shaft 12. The second end cap 16 abuts against the outer ring of the deep groove ball bearing 15 at one end, and the spacer sleeve B17 abuts against the outer ring of the deep groove ball bearing 15 at the other end. The fit between the two deep groove ball bearings 15 and the driven stepped shaft 12 ensures the reliable installation of the driven gear 11.

[0043] The driving gear 2 and the driven gear 11 are meshed and transmitted, and are arranged vertically and perpendicularly to each other.

[0044] The first end cover 6 and the second end cover 16 are both connected to the box body 1 by screws 18. The connection method using the screws 18 is simple and reliable, and is convenient for assembly, disassembly and maintenance.

[0045] The setting of the joint bearing 5 plays a role in adjusting the direction, which can allow the driving gear 2 to deviate slightly, thereby eliminating the extrusion stress between the driving gear 2 and the driven gear 11, avoiding tooth jumping, gear jamming or even damage. The deep groove ball bearing 15 can withstand radial force and axial force at the same time, and can withstand large torque.

[0046] The driving gear 2 and the driven gear 11 are arranged in the box body 1, which has a certain protective effect compared to the open gear transmission. In addition, a sealing ring 8 is provided, so the gears are no longer exposed to the outside, are not easy to accumulate dust and impurities, and have less wear, which is conducive to improving transmission efficiency.

[0047] Working Principle: The spline shaft passes through the spline hole. The rotation of the spline shaft drives the driving gear 2 to rotate. Through the meshing transmission between the driving gear 2 and the driven gear 11, the output shaft (filter cloth drive shaft) rotates, and then the filter cloth moves, realizing the transmission. The pressure plate in the filter press also moves, but due to factors such as the overall rigidity of the equipment and various errors, it is not possible to achieve the requirement of completely non-bending. Therefore, the pressure plate will deflect, and the gearbox will be stressed. At this time, the force needs to be released. The configuration of the spherical bearing 5 allows the driving gear 2 to deflect slightly, which is equivalent to flexibility compensation, realizing the force release.

[0048] In the description of the present invention, it should be understood that the terms "one end", "the other end", "both ends", "upper", "lower", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified and limited, it should be noted that the term "connection" should be understood in a broad sense, for example, it can be a mechanical connection or an electrical connection, or it can be the internal communication between two elements, it can be a direct connection, or it can be an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0049] The above are only preferred embodiments of the utility model and are not intended to limit the utility model.
