DETAILED DESCRIPTION
[0024] 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.
[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0026] Reference Figure 1-Figure 3 , the utility model provides a horizontal transmission box, comprising:
[0027] The box body 1 has a partition 8 fixedly connected therein, which divides the box body 1 into a first chamber 12 and a second chamber 13. The first chamber 12 is provided with an opening on one side away from the second chamber 13, and a bottom plate 6 is detachably connected to the opening.
[0028] The fixed transmission assembly includes an intermediate connecting transmission member disposed in the second chamber 13, the output end of the intermediate connecting transmission member being in driving connection with the output shaft, the intermediate connecting transmission member and the output shaft being respectively in driving connection with the actuator, and the end of the intermediate connecting transmission member away from the output shaft being located in the first chamber 12;
[0029] The replaceable transmission assembly includes a transmission shaft gear 3 detachably connected to the intermediate connecting transmission member and an input shaft detachably arranged in the first chamber 12. The input shaft is transmission-connected to the transmission shaft gear 3. The end of the input shaft away from the transmission shaft gear 3 passes through the base plate 6 and is transmission-connected to the drive motor.
[0030] The main function of the base plate 6 is to enable rapid replacement of the transmission shaft gear 3 and input shaft through its assembly and disassembly. It also stabilizes the rotation of the output shaft and intermediate connecting transmission member during operation of the horizontal transmission case. The intermediate connecting transmission member primarily transmits the power of the transmission shaft gear 3 to the output shaft and the actuator. The input shaft primarily transmits the power of the motor to the transmission shaft gear 3. The output shaft ultimately transmits the power of the motor to the actuator, namely the rolling mill. Overall, the present invention, by providing a replaceable transmission assembly, allows for the rapid replacement of matching transmission shaft gears and input shafts with different gear ratios, thereby achieving the goal of changing the speed ratio of the entire horizontal transmission case to meet customer requirements for varying speed ratios.
[0031] A further optimized solution is that the intermediate connecting transmission member includes a transmission gear shaft 4, the end of the transmission gear shaft 4 close to the gear is transmission-connected to the output shaft, and the transmission shaft gear 3 is detachably connected to the end of the transmission gear shaft 4 away from the gear.
[0032] As a further optimized solution, a first through hole 9 is opened on the partition 8 , and the end of the transmission gear shaft 4 away from the gear passes through the first through hole 9 and is rotatably connected to the side wall of the bottom plate 6 .
[0033] like Figure 2 As shown, a keyway 14 is provided on the side wall of the transmission gear shaft 4 away from the gear. The transmission shaft gear 3 is connected to the transmission gear shaft 4 through the key and the keyway 14. When the transmission shaft gear 3 needs to be replaced, it only needs to be pulled outward along the axis of the transmission gear shaft 4.
[0034] like Figure 1 As shown, a bearing matching the transmission gear shaft 4 is provided on the bottom plate 6 to improve the stability of the transmission gear shaft 4 during rotation.
[0035] like Figure 2 As shown, the end of the transmission gear shaft 4 away from the keyway 14 passes through the side wall of the box body 1, so that the transmission gear shaft 4 can transmit power to the roll box of the rolling mill. A bearing is provided between the transmission gear shaft 4 and the side wall of the box body 1 to achieve rotational connection.
[0036] According to a further optimized solution, the input shaft includes an input gear shaft 2, the gear of the input gear shaft 2 is in transmission connection with the transmission shaft gear 3, and one end of the input gear shaft 2 close to the transmission shaft gear 3 is detachably rotatably connected to the partition 8.
[0037] As a further optimized solution, a second through hole 10 is opened on the bottom plate 6, and the end of the input gear shaft 2 away from the transmission shaft gear 3 slides through the second through hole 10 and is connected to the motor for transmission.
[0038] like Figure 2 As shown, a bearing matching the input gear shaft 2 is provided in the second through hole 10 .
[0039] According to a further optimization scheme, the output shaft includes a passive gear shaft 7, which is rotatably connected in the second chamber 13, the gear of the passive gear shaft 7 is engaged with the gear of the transmission gear shaft 4, and the end of the passive gear shaft 7 away from the box body 1 is transmission-connected to the execution device.
[0040] like Figure 3 As shown, bearings are respectively provided on two opposite side walls of the second chamber to match the two ends of the driven gear shaft 7.
[0041] In a further optimized solution, the bottom plate 6 and the opening of the first chamber 12 are detachably connected by bolts.
[0042] like Figure 2 As shown, when the speed ratio needs to be changed, the on-site personnel loosen the bolts on the bottom plate 6 and pull the bottom plate 6 out along the axis of the input gear shaft 2. During the withdrawal process, the bottom plate 6 is separated from the transmission gear shaft 4 and the input gear shaft 2. After that, the transmission shaft gear 3 is pulled out from the transmission gear shaft 4, the input gear shaft 2 is removed from the partition 8, and the matching transmission shaft gear 3 and input gear shaft 2 of the new speed ratio are replaced. Finally, the bottom plate 6 is reinstalled on the housing 1 to adjust the speed ratio to meet the needs of the new equipment.
[0043] According to a further optimization scheme, the oil box 5 is fixedly connected to the side of the bottom plate 6 away from the first chamber 12 , the bottom plate 6 is communicated with the interior of the oil box 5 , and the end of the input gear shaft 2 away from the transmission shaft gear 3 passes through the side wall of the oil box 5 .
[0044] like Figure 2 、 Figure 3 As shown, the oil box 5 is buckled on the side of the bottom plate 6 away from the first chamber 12. Its main function is to recover the lubricating oil. During the process of replacing the transmission shaft gear 3 and the input gear shaft 2, the lubricating oil in the first chamber 12 is recovered.
[0045] Further optimization scheme, such as Figure 2 As shown, an oil seal 11 is provided on the side wall of the oil box 5 , and the oil seal 11 fits against the side wall of the input gear shaft 2 to prevent the lubricating oil in the oil box 5 from leaking along the outer wall of the input gear shaft 2 .
[0046] The operating process of this embodiment is as follows: After the on-site operator replaces the required transmission shaft gear 3 and input gear shaft 2, they connect the drive motor to the input gear shaft 2. The drive motor is then started, rotating the input gear shaft 2. The gear on the input gear shaft 2 meshes with the transmission shaft gear 3, which in turn drives the transmission gear shaft 4. The rotation of the transmission gear shaft 4, through its gear, drives the gear on the driven gear shaft 7, which in turn drives the driven gear shaft 7. The driven gear shaft 7 and transmission gear shaft 4 transmit power to the roll box of the rolling mill, driving the rolling mill. While transmitting power, the speed ratio can be changed to meet production requirements.
