Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel wire rope production equipment, in particular to a flexible connecting mechanism for connecting a basket device and a main shaft of a transmission box of a large-scale basket-type rope twisting equipment. BACKGROUND

[0002] In the design of small and medium-sized basket-type twisting equipment, the main shaft of the main transmission box is generally supported at one end by a self-aligning roller bearing on the main transmission box body and connected to the basket device at the other end by a flange to form a rigid body, which is supported by a supporting roller device below the basket device. At the output end of the main transmission box main shaft, the main shaft and the main transmission box body are generally sealed by a labyrinth seal, leaving a certain gap between the main shaft and the box. On the one hand, this prevents the basket device from sinking after a long period of operation, and on the other hand, the labyrinth seal also ensures that no lubricating oil is thrown out of the box.

[0003] However, when designing a super-large basket device structure, the weight of the basket device itself plus the weight of the fully loaded I-beam can reach several hundred tons (for example, an 8 / 2500 basket weighs nearly 500 tons). After a long period of operation, the ground foundation will sink and the supporting top wire will retreat, which will cause the basket device to sink. For the main transmission box main shaft and the box with a labyrinth seal structure, it is fatal, which may cause the labyrinth device to burn out, or even damage the main transmission box main shaft and the basket device main shaft, seriously affecting normal production.

[0025] Please refer to Figures 1-3 The present application provides a flexible coupling mechanism for the basket device and the main shaft of the transmission box of a large basket type rope twisting device, which comprises a main shaft transmission box body 12, a main transmission box main shaft 3 installed at the output end of the main shaft transmission box, a basket device 7 and a basket main shaft 9. The basket device 7 is installed on the right end face of the main transmission box main shaft 3. A gear 2 is arranged on the main transmission box main shaft 3 near the left side area. A drum gear 6 is installed on the main transmission box main shaft 3 near the right side end position. An inner tooth coupling disc 5 is installed on the left side end face of the basket device 7. The inner tooth coupling disc 5 is sleeved on the outer side end face of the drum gear 6, and the meshing teeth on the inner side end face are engaged with the drum gear 6. A positioning sleeve 8 is fixedly installed on the right side end face of the inner tooth coupling disc 5, and the positioning sleeve 8 is positioned and coupled with the basket device 7.

[0026] The present application will be described in detail below. Figure 2 and Figure 3Wherein, it is worth mentioning that the inner cavity left side of the inner tooth coupling disc 5 is provided with an inner spherical surface B, the ring inner cavity of the positioning sleeve 8 is provided with an inner spherical surface A, the inner spherical surface A and the inner spherical surface B form a spherical surface, and the outer spherical surfaces C and D on the left and right sides of the bevel gear 6 are respectively embedded in the corresponding inner spherical surfaces A and B. After the inner tooth coupling disc 5 and the positioning sleeve 8 are assembled, the inner spherical surface A and the inner spherical surface B form a spherical surface. When the basket device 7 sinks or deviates, the basket device 7 and the inner tooth coupling disc 5 combination can form an angle with the main transmission box main shaft 3 and the bevel gear 6 combination, so as to protect the main transmission box main shaft 3 and the basket main shaft 9 from being damaged, while not affecting normal transmission. The inner spherical surface and the outer spherical surface cooperation mechanism can bear downward pressure load, and can also bear the axial load generated by the forward movement of the basket device.

[0027] It should be noted that, in order to further ensure the stability and accuracy of the cooperation, in the embodiment, the diameters of the inner spherical surfaces in the inner tooth coupling disc 5 and the positioning sleeve 8 and the outer spherical surfaces on the left and right sides of the bevel gear 6 are the same, and the outer spherical surfaces on the left and right sides of the bevel gear 6 are accurately matched with the corresponding inner spherical surfaces A and B.

[0028] In addition, in an embodiment, the meshing teeth on the inner side of the inner tooth coupling disc 5 and the bevel gear 6 have the same modulus and the same number of teeth.

[0029] In addition, in an embodiment, the first support bearing 1 and the second support bearing 4 are respectively arranged on the left and right sides of the gear 2 on the main shaft transmission box body 12, and the main transmission box main shaft 3 is transitionally matched with the first support bearing 1 and the second support bearing 4, so that when the driving mechanism drives the gear 2 to rotate, the left and right sides of the main transmission box main shaft 3 are supported by the support bearings 1 and 4, so that the transmission box main shaft 3 is more stable.

[0030] In addition, in an embodiment, the basket main shaft 9 is coupled to the right end face of the basket device 7 through bolts, and the bolt coupling positions are reinforced with reinforcing ribs, so as to improve the connection strength of the basket main shaft 9 and effectively avoid the deviation of the basket main shaft 9 caused by the additional tangential load due to the settlement of the basket device during operation.

[0032] In addition, in an embodiment, the gear 2 and the bevel gear 6 are both key connected with the main transmission box main shaft 3.

[0033] When the driving mechanism drives the gear 2 to rotate, the main transmission box main shaft 3 rotates, so that the drum gear 6 drives the inner tooth coupling disc 5, thereby driving the basket device 7 to rotate, and in the large basket device structure, due to the self weight of the basket device plus the very large weight of the full load I-beam, in the normal operation process, the ground foundation will still appear obvious settlement and the top wire of the supporting support wheel will retreat, which will cause the basket device to sink, at this time, the basket device 7 and the inner tooth coupling disc 5 combination can form an angle with the main transmission box main shaft 3 and the drum gear 6 combination, so as to protect the main transmission box main shaft 3 and the basket main shaft 9 from being damaged, and at the same time, the normal transmission is not affected, and the cooperation between the inner and outer spherical surfaces between the two can withstand the downward pressure load, and can also withstand the axial load generated by the forward movement of the basket device, thereby effectively avoiding the damage to the equipment caused by the settlement of the basket device 7, and protecting the main transmission box main shaft 3 and the basket device main shaft 9 from fatigue fracture.

[0034] The above is only a specific embodiment of the application, but the protection scope of the application is not limited thereto, any change or replacement without creative labor should be covered in the protection scope of the application. Therefore, the protection scope of the application should be limited by the protection scope defined in the claims.
