Description

Technical Field

[0001] This utility model relates to the field of ceramic tile production technology, specifically to a structure for preventing breakage of the transmission shaft in a ceramic tile kiln. Background Technology

[0002] Tiles are now an indispensable component of building materials, although they come in many varieties and have different manufacturing processes. However, for high-end tiles, uniform firing, thick body, and absence of cracks and other defects are basic requirements.

[0003] In the ceramic tile production process, ceramic tiles are placed on many closely spaced horizontal refractory rollers, and the rotation of the rollers transports the ceramics from the kiln head to the kiln tail. Because a large number of horizontal refractory rollers need to rotate synchronously, a long transmission shaft is required to drive multiple horizontal refractory rollers simultaneously. This places high demands on the installation of the transmission shaft. However, during installation, the transmission shaft is prone to significant coaxiality deviations and bearing quality problems, which increases the probability of shaft breakage and leads to higher maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies in the existing technology and provide a structure for preventing the breakage of the transmission shaft of a ceramic tile kiln.

[0005] One embodiment of this utility model provides a structure for preventing the breakage of the transmission shaft in a ceramic tile kiln, comprising:

[0006] A main drive shaft, wherein at least one end of the main drive shaft is provided with a connecting member;

[0007] At least one drive shaft is provided, which is fixedly connected to one end of the main drive shaft via the connector, and the drive shaft is provided with a plurality of transmission parts for transmission cooperation with the transport device of the tile kiln.

[0008] A power module is disposed on one side of the main drive shaft and is connected to the main drive shaft via a transmission mechanism.

[0009] In some alternative embodiments, the connector is a splined coupling sleeve, and one end of the main drive shaft and one end of the driven shaft are fixedly inserted into the splined coupling sleeve.

[0010] In some alternative implementations, the anti-breakage shaft structure for ceramic kiln drives includes two of the aforementioned drive shafts;

[0011] The main drive shaft is provided with connectors at both ends, and the connectors are connected to the drive shaft.

[0012] In some alternative implementations, the axial length of the main drive shaft is less than the axial length of the driven shaft.

[0013] In some optional embodiments, both the main drive shaft and the driven drive shaft are provided with a plurality of drive parts, which are arranged sequentially along the axial direction of the driven drive shaft.

[0014] In some alternative embodiments, the anti-breakage shaft structure for ceramic kiln transmission also includes a base on which multiple bearings are provided. The main transmission shaft is rotatably engaged with at least two of the bearings, and the driven transmission shaft is rotatably engaged with at least two of the bearings.

[0015] In some alternative embodiments, the anti-breakage shaft structure for the ceramic kiln drive also includes a base on which an oil groove is provided extending axially from the drive shaft, the oil groove gradually extending downward in a direction away from the power module.

[0016] In some optional embodiments, the transmission mechanism includes a driving gear, a transition gear, and a driven gear. The power module is drivenly connected to the driving gear, the driven gear is disposed on the main drive shaft, and the transition gear is disposed between the driving gear and the driven gear, and meshes with the driving gear and the driven gear respectively.

[0017] In some alternative embodiments, the transmission mechanism further includes a gearbox, in which the driving gear, the transition gear, and the driven gear are all disposed.

[0018] Compared to existing technologies, the anti-breakage shaft structure of this utility model for ceramic kiln transmission divides the transmission shaft into a main transmission shaft and a driven transmission shaft. Through segmented design, the straightness requirements of the entire transmission shaft during installation can be reduced, thereby reducing the probability of shaft breakage due to stress concentration after bending, achieving the effect of preventing shaft breakage. Moreover, even if shaft breakage occurs, only the corresponding part needs to be replaced, without the need for overall replacement, saving costs. Furthermore, the shorter main transmission shaft helps to increase the rigidity of the main transmission shaft, preventing shaft breakage.

[0019] To provide a clearer understanding of this invention, the specific embodiments of this invention will be described below in conjunction with the accompanying drawings. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 4 One embodiment of this utility model provides a transmission anti-breakage shaft structure for a ceramic tile kiln, comprising: a main transmission shaft 10, at least one driven transmission shaft 20, and a power module 30.

[0030] At least one end of the main drive shaft 10 is provided with a connector 11.

[0031] The drive shaft 20 is detachably connected to one end of the main drive shaft 10 via the connector 11. The detachable connection between the main drive shaft 10 and the drive shaft 20 via the connector 11 facilitates subsequent inspection and maintenance, and allows for the separate inspection and replacement of either the main drive shaft 10 or the drive shaft 20. The drive shaft 20 is provided with several transmission parts 21 for transmission with the transport device of the tile kiln.

[0032] The power module 30 is located on one side of the main drive shaft 10 and is connected to the main drive shaft 10 via the transmission mechanism 31. The power module 30 drives the main drive shaft 10 to rotate via the transmission mechanism 31, which in turn drives the driven shaft 20 to rotate. The rotation of the driven shaft 20 drives the transmission part 21 to rotate, and the transmission part 21 can drive the refractory roller of the ceramic tile kiln to rotate.

[0033] The anti-breakage shaft structure of this ceramic kiln transmission adopts a segmented design, with the main drive shaft 10 and the driven drive shaft 20 connected to form a relatively long transmission structure. While meeting the needs of the equipment, the main drive shaft 10 and the driven drive shaft 20 can be installed separately, which reduces the straightness requirements of the transmission structure during installation. This helps to reduce the probability of shaft breakage due to stress concentration after the transmission structure bends. Even if a shaft breakage occurs, only the corresponding part needs to be replaced, without replacing the whole structure. Only the damaged part needs to be replaced, thus saving costs.

[0034] In some optional embodiments, the connecting member 11 is a splined coupling sleeve, with one end of the main drive shaft 10 and one end of the driven drive shaft 20 detachably inserted into the splined coupling sleeve. The splined coupling sleeve is used to transmit the movement and torque of the main drive shaft 10 to the driven drive shaft 20. The splined coupling sleeve enables a fixed connection between the main drive shaft 10 and the driven drive shaft 20, and the splined coupling sleeve is circumferentially limited to both the main drive shaft 10 and the driven drive shaft 20, allowing the splined coupling sleeve, the main drive shaft 10, and the driven drive shaft 20 to rotate synchronously. Of course, the structure of the connecting member 11 is not limited to this, and those skilled in the art can choose other suitable structures based on the teachings of this utility model. The connecting member 11 can also be a connecting flange or other suitable connection structure.

[0035] The principle of the spline coupling sleeve is similar to that of the spline shaft. The spline coupling sleeve is provided with two mounting holes. The inner wall of the mounting holes is provided with multiple axially extending first keyways. The main drive shaft 10 and the driven shaft 20 are also provided with multiple axially extending second keyways. Taking the installation of the main drive shaft 10 as an example: after the main drive shaft 10 is inserted into the mounting hole, the part located between the adjacent first keyways extends into the second keyway, and the part located between the adjacent second keyways extends into the first keyway, thereby enabling the main drive shaft 10 to be installed with the mounting hole.

[0036] The main drive shaft 10 and the driven drive shaft 20 can be detachably fixed to the spline coupling sleeve by means of interference fit or threaded locking, etc., and this example is not limited to this one.

[0037] In some optional embodiments, the anti-breakage shaft structure of the ceramic kiln transmission includes two driven shafts 20; both ends of the main transmission shaft 10 are provided with connecting parts 11, which are connected to the transmission shafts respectively, so that the main transmission shaft 10 synchronously drives the two driven shafts 20 to rotate. Of course, in some optional embodiments, the anti-breakage shaft structure of the ceramic kiln transmission may also include three or more transmission shafts, and the driven shafts 20 connected to the main transmission shaft 10 can also be detachably connected to other driven shafts 20 through a suitable connection structure, so that the main transmission shaft 10 synchronously drives more driven shafts 20 to rotate, which is beneficial to shortening the axial length of the driven shafts 20. For example, two driven shafts 20, the main transmission shaft 10 and two other driven shafts 20 are arranged sequentially along the axis of the main transmission shaft 10, and adjacent driven shafts 20 can also be detachably connected through spline couplings.

[0038] In some alternative implementations, the axial length of the main drive shaft 10 is less than the axial length of the driven shaft 20. The shorter main drive shaft 10 is beneficial to increasing the rigidity of the main drive shaft 10, which is beneficial to improving the stability of the transmission between the main drive shaft 10 and the power module 30, and also helps to avoid shaft breakage.

[0039] In some alternative embodiments, both the main drive shaft 10 and the driven drive shaft 20 are provided with multiple drive sections 21, which are arranged sequentially along the axial direction of the driven drive shaft 20. Drive sections 21 can also be provided on the main drive shaft 10, thereby ensuring a stable interval between all drive sections 21, preventing the inability to arrange refractory rollers at the corresponding positions on the main drive shaft 10, and meeting the transmission requirements for multiple evenly arranged refractory rollers.

[0040] In one embodiment, all adjacent transmission parts 21 are spaced apart by a suitable preset distance.

[0041] The specific structure of the transmission part 21 can be selected according to the actual needs. For example, in this embodiment, the transmission part 21 adopts a first helical gear, and the refractory roller meshes with the first helical gear through the second helical gear 50, thereby realizing the transmission between the transmission part 21 and the refractory roller.

[0042] In some optional embodiments, the anti-breakage shaft structure of the ceramic kiln drive also includes a base 40, on which multiple bearings 41 are mounted. The main drive shaft 10 is rotatably engaged with at least two bearings 41, and the driven shaft 20 is also rotatably engaged with at least two bearings 41. The bearings 41 support the main drive shaft 10 and the driven shaft 20, improving their rotational stability. During installation, since the length of the overall transmission structure is distributed across the main drive shaft 10 and the driven shaft 20, their lengths are not excessive. Therefore, the straightness requirements between the multiple bearings 41 are reduced, and the precision and quality requirements of the bearings 41 are also reduced, which helps to reduce costs.

[0043] Please see Figure 5 In some optional embodiments, the anti-breakage shaft structure for the ceramic kiln drive also includes a base 40, on which an oil groove 42 extending axially from the drive shaft 20 is provided. The oil groove 42 can be used to store lubricating oil, and the drive unit 21 can extend into the oil groove 42. The oil groove 42 gradually extends downward in the direction away from the power module 30, which is beneficial for guiding and collecting the lubricating oil. In addition, in this embodiment, the bearing 41 is positioned above the lubricating oil level by a support frame 44 mounted on the base 40, thus preventing the bearing 41 from being immersed in the lubricating oil.

[0044] In some optional embodiments, the transmission mechanism 31 includes a driving gear 32, a transition gear 33, and a driven gear 34. The power module 30 is drivenly connected to the driving gear 32, the driven gear 34 is disposed on the main drive shaft 10, and the transition gear 33 is disposed between the driving gear 32 and the driven gear 34, meshing with both the driving gear 32 and the driven gear 34 respectively. The power module 30 drives the driving gear 32 to rotate, which in turn drives the transition gear 33 and the driven gear 34 to rotate, thereby driving the main drive shaft 10. Of course, the specific structure of the transmission mechanism 31 can be selected according to actual needs and is not limited to this example. For example, depending on actual needs, the transmission mechanism 31 can also adopt a reduction gear set.

[0045] In some alternative embodiments, the transmission mechanism 31 further includes a gearbox 35, in which the driving gear 32, the intermediate gear 33, and the driven gear 34 are all disposed, to prevent dust and other impurities in the environment from falling on the driving gear 32, the intermediate gear 33, and the driven gear 34.

[0046] The specific structure of the power module 30 can be selected according to the actual needs. In this embodiment, the power module 30 adopts a motor, which is installed on one side of the gearbox 35, and the output shaft of the motor is connected to the drive gear 32.

[0047] Please see Figure 6In this embodiment, an oil cap 43 is also provided on the top of the base 40. The main drive shaft 10, the driven shaft 20, the transmission part 21, the bearing 41, and the main drive gear are located between the oil cap 43 and the base 40, which helps to prevent dust and other impurities in the environment from falling onto the main drive shaft 10, the driven shaft 20, the transmission part 21, the bearing 41, and the main drive gear on the base 40.

[0048] In addition, in this embodiment, the base 40 is divided into a first base 45 and a second base 46. The gearbox 35 is disposed between the first base 45 and the second base 46. Part of the main drive shaft 10 passes through the gearbox 35, and both ends of the main drive shaft 10 extend to the first base 45 and the second base 46. Two drive shafts 20 are respectively disposed on the first base 45 and the second base 46. The gearbox 35 is provided with gears that rotate with the main drive shaft 10. Oil grooves 42 can be provided on the gearbox 35 on both the first base 45 and the second base 46. The purpose of this design is to place the main drive shaft 10, the motor, and the transmission structure on the gearbox 35, which is beneficial to improve the strength of the structure, reduce shaking, and improve transmission stability.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
