Description

Technical Field

[0001] The utility model relates to the field of steering boxes, in particular to a combined transmission steering box. Background Art

[0002] The transmission steering box can ensure the transmission relationship and change the transmission direction according to the needs. However, the existing transmission steering boxes are all single steering boxes, that is, the transmission direction is fixed and cannot be changed. If the transmission direction of this type of fixed transmission steering box is to be changed, it can only be achieved by changing the installation angle. Therefore, the existing transmission steering box is limited in use and installation due to the single transmission direction, and lacks market competitiveness. Utility Model Content

[0003] Aiming at the defects in the prior art, the function of adjustable transmission direction is added to improve market competitiveness. The utility model provides a combined transmission steering box, including a first steering box and a second steering box; the first steering box is provided with a first housing, a first rotating shaft and a second rotating shaft; one end of the first rotating shaft and one end of the second rotating shaft are rotatably connected in the first housing, and the other end of the first rotating shaft extends out of the first housing; the second steering box is provided with a second housing, a third rotating shaft and a fourth rotating shaft; one end of the third rotating shaft and one end of the fourth rotating shaft are rotatably connected in the second housing, and the other end of the third rotating shaft and / or the other end of the fourth rotating shaft extends out of the second housing; the other end of the second rotating shaft extends into the second housing and is transmission-connected with the third rotating shaft, thereby making the first rotating shaft, the second rotating shaft, the third rotating shaft and the fourth rotating shaft linked, and the first steering box and the second steering box can rotate relatively.

[0004] The beneficial effect of the device is that since the second rotating shaft can rotate relative to the first shell and the second shell, the first steering box and the second steering box can also rotate relative to each other. Compared with the existing right-angle steering box, the steering angle is adjustable, which can meet the needs and installation requirements of more equipment, while ensuring the transmission efficiency and having stronger market competitiveness.

[0005] Preferably, the first rotating shaft and the second rotating shaft, the second rotating shaft and the third rotating shaft, and the third rotating shaft and the fourth rotating shaft are all connected by bevel gear transmission.

[0006] Preferably, the angle between the first rotating shaft and the second rotating shaft, the angle between the second rotating shaft and the third rotating shaft, and the angle between the third rotating shaft and the fourth rotating shaft are all 90°. Like the existing right-angle transmission box, the reversing angle is 90°. The equipment that can be used by the existing right-angle steering box can still be used after the first steering box and the second steering box are combined into a whole, and the adaptability is stronger.

[0007] Preferably, the other end of the first rotating shaft extends out of the first housing, and the first rotating shaft and the first housing are rotatably connected via a bearing. The first rotating shaft only extends to the middle of the first housing to avoid conflict with the second rotating shaft, but the first rotating shaft and the first housing are rotatably connected using two bearings to ensure the rotation balance of the first rotating shaft.

[0008] Preferably, the second rotating shaft passes through the middle of the first shell and then passes through the side wall of the first shell, and the second rotating shaft and the first shell, as well as the second rotating shaft and the second shell, are rotatably connected via bearings.

A single bearing is provided between the third rotating shaft and the two side walls of the second housing, and one end of the third rotating shaft extends out of the second housing as an intermediate shaft or a spare.

[0010] Preferably, the fourth rotating shaft is rotatably connected to the second housing via a bearing. Two bearings are arranged between the fourth rotating shaft and the second housing, and similarly, the rotation is more stable.

[0011] Preferably, the first shell and the second shell are both detachable.

[0012] Preferably, the first rotating shaft outside the first housing and the fourth rotating shaft outside the second housing are both quadrangular rods or hexagonal rods.

DETAILED DESCRIPTION

[0018] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0019] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0020] like Figure 1 and Figure 2 As shown, this embodiment provides a combined transmission steering box, including a first steering box 1 and a second steering box 2, and the first steering box 1 and the second steering box 2 can also rotate relative to each other. Compared with the existing right-angle steering box, the steering angle is adjustable, which can meet the needs and installation requirements of more equipment, while ensuring transmission efficiency and having stronger market competitiveness. The specific structure of the first steering box 1 and the second steering box 2 is as follows:

[0021] like Figure 3 As shown, the first steering box 1 is provided with a first housing 3, a first rotating shaft 4 and a second rotating shaft 5; one end of the first rotating shaft 4 and one end of the second rotating shaft 5 are rotatably connected in the first housing 3, and the other end of the first rotating shaft 4 extends out of the first housing 3. Specifically, the other end of the first rotating shaft 4 extends out of the first housing 3, and the first rotating shaft 4 and the first housing 3 are rotatably connected through a bearing 6. The first rotating shaft 4 only extends to the middle of the first housing 3 to avoid conflict with the second rotating shaft 5, but the first rotating shaft 4 and the first housing 3 are rotatably connected by two bearings 6 to ensure the rotation balance of the first rotating shaft 4. The second rotating shaft 5 passes through the middle of the first housing 3 and then passes through the side wall of the first housing, and the second rotating shaft 5 and the first housing 3 are rotatably connected through a bearing 6. A single bearing 6 is provided between the second rotating shaft 5 and the two side walls of the first housing 3.

[0022] In this embodiment, the angle between the first rotating shaft 4 and the second rotating shaft 5 is 90°, and the first rotating shaft 4 and the second rotating shaft 5 are connected by a bevel gear 11, that is, the first rotating shaft 4 is provided with a coaxially fixed bevel gear 11, and the second rotating shaft 5 is provided with another coaxially fixed bevel gear 11, and the two bevel gears 11 are meshed for transmission.

[0023] The second steering box 2 is provided with a second housing 7, a third rotating shaft 8 and a fourth rotating shaft 9. One end of the third rotating shaft 8 and one end of the fourth rotating shaft 9 are rotatably connected in the second housing 7, and the other end of the third rotating shaft 8 and the other end of the fourth rotating shaft 9 extend out of the second housing 7, or only the other end of the fourth rotating shaft 9 extends out of the second housing 7. The other end of the second rotating shaft 5 extends into the second housing 7 and is transmission-connected with the third rotating shaft 8. Specifically, the second rotating shaft 5 and the third rotating shaft 8, as well as the third rotating shaft 8 and the fourth rotating shaft 9 are transmission-connected through a bevel gear 11. The bevel gear 11 here has the same structure as the bevel gear 11 of the first steering box 1, and both adopt two bevel gears 11 meshing transmission, and the transmission angle is 90°. That is, the angle between the first rotating shaft 4 and the second rotating shaft 5, the angle between the second rotating shaft 5 and the third rotating shaft 8, and the angle between the third rotating shaft 8 and the fourth rotating shaft 9 are all 90°. Like the existing right-angle transmission box, the reversing angle is 90°. The equipment that can be used by the existing right-angle steering box can still be used after the first steering box 1 and the second steering box 2 are combined into a whole, and the adaptability is stronger.

[0024] In this embodiment, one end of the third rotating shaft 8 passes through the middle of the second housing and then passes through the side wall of the second housing, and the third rotating shaft 8 is rotatably connected to the second housing via a bearing 6. A single bearing 6 is provided between the third rotating shaft 8 and the two side walls of the second housing 7, and one end of the third rotating shaft 8 extends out of the second housing as an intermediate shaft or a spare. The fourth rotating shaft 9 is rotatably connected to the second housing via a bearing 6. Two bearings 6 are provided between the fourth rotating shaft 9 and the second housing 7, and similarly, the rotation is more stable.

[0025] In this embodiment, the first rotating shaft 4 can be an input shaft or an output shaft, and correspondingly, the fourth rotating shaft 9 is an output shaft or an input shaft, and the first rotating shaft 4 located outside the first housing 3 and the fourth rotating shaft 9 located outside the second housing 7 are both quadrangular rods or hexagonal rods 10. The first rotating shaft 4 and the fourth rotating shaft 9 are used as input shafts or output shafts, and adopt a multi-sided rod structure, which is convenient for connection with other devices.

[0026] Since the first rotating shaft 4 and the second rotating shaft 5, the second rotating shaft 5 and the third rotating shaft 8, and the third rotating shaft 8 and the fourth rotating shaft 9 in this embodiment are all connected by bevel gears 11, the second rotating shaft 5 can rotate relative to the first housing 3 and the second housing 7, so the first steering box 1 and the second steering box 2 can also rotate relatively, and the first rotating shaft 4, the second rotating shaft 5, the third rotating shaft 8 and the fourth rotating shaft 9 form a linkage relationship, and the relative angle between the first steering box 1 and the second steering box 2 can be changed according to the specific equipment or installation angle to meet the specific assembly requirements. Compared with the existing fixed transmission steering box, it can adapt to more equipment and can also meet more complex installation environments, so it has stronger market competitiveness.

[0027] In addition, in order to facilitate maintenance and repair, the first shell 3 and the second shell 7 in this embodiment can be disassembled.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
