It includes a support frame, a fixed conical roller group, a movable conical roller group, and a reduction motor. A guide rail module is fixedly connected inside the support frame. The movable conical roller group is slidably connected to the support frame via the guide rail module. The fixed conical roller group is located directly below the movable conical roller group and is fixedly installed inside the support frame. The reduction motor is fixedly installed inside the support frame, and its output shaft is connected to an adjustable transmission mechanism. In this utility model, as the height of the conical roller changes, the length of the extended transmission component changes. Simultaneously, the connecting rod drives the inner support seat to rotate a certain angle inside the spherical seat. Multiple sets of rolling balls remain movable within the grooves of both the inner support seat and the spherical seat. Therefore, even when the height of the movable conical roller group changes, the reduction motor can still drive the movable conical roller group to rotate and roll the ring, improving the ring rolling efficiency.

Description

Technical Field

[0001] This utility model relates to the field of ring rolling mill technology, and in particular to a conical roller transmission system for a radial ring rolling mill. Background Technology

[0002] Axial and radial ring rolling mills are key equipment used for rolling and expanding ring-shaped parts (such as bearing rings, gear rings, flanges, etc.). Through the synergistic action of axial and radial roller systems, they achieve wall thickness reduction, diameter expansion, and geometric precision shaping of ring blanks. The conical roller drive system, as one of its core components, is mainly used to transmit power, adjust the roller system's motion trajectory, or achieve speed / torque matching during the rolling process, directly affecting the equipment's processing accuracy, efficiency, and stability.

[0003] However, the existing ring rolling mill uses a double cone roller method, where one cone roller has a fixed position and the other cone roller can be adjusted. However, the position of the adjusted cone roller changes, and the existing ring rolling mill cannot drive it, resulting in low ring rolling efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art and to propose a radial conical roller transmission system for a ring rolling mill.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a conical roller transmission system for a radial ring rolling mill, comprising a support, a fixed conical roller group, a movable conical roller group, and a reduction motor. A guide rail module is fixedly connected inside the support. The movable conical roller group is slidably connected to the support through the guide rail module. The fixed conical roller group is located directly below the movable conical roller group and is fixedly installed inside the support. The reduction motor is fixedly installed inside the support. The output shaft of the reduction motor is driven by an adjustable transmission mechanism. The movable conical roller group includes a conical roller body and a roller seat. The adjustable transmission mechanism includes an extension transmission component and an angle transmission component. The angle transmission component is driven by the conical roller body.

[0006] Preferably, the angle transmission assembly includes a ball seat, a ball, a ball ring, an inner support seat, and a connecting rod, with the end of the connecting rod fixedly installed in the middle of the inner support seat.

[0007] Preferably, multiple sets of rolling balls are distributed in a ring and are movably engaged in the outer groove of the inner support seat, with the ball rings movably engaged in the outer side of the multiple sets of rolling balls.

[0008] Preferably, multiple sets of rolling balls are movably connected in the inner groove of the spherical seat, and the ball ring is movably connected in the middle position between the inner support seat and the spherical seat.

[0009] Preferably, the extended transmission assembly includes a first universal joint, a sleeve, a connecting rod, and a second universal joint, with the first universal joint fixedly connected to the other end of the connecting rod.

[0010] Preferably, the other end of the first universal joint is fixedly connected to the sleeve, and the sleeve is slidably engaged with the connecting rod through a keyway.

[0011] Preferably, the second universal joint is fixedly connected to the other end of the connecting rod, and the second universal joint is fixedly connected to the output shaft of the geared motor.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, during the change of the height position of the conical roller body, the length of the extended transmission component changes, and at the same time, the connecting rod drives the inner support seat to rotate a certain angle inside the spherical seat. Meanwhile, multiple sets of rolling balls are always moving in the grooves of both the inner support seat and the spherical seat. Thus, when the height position of the movable conical roller group changes, the reduction motor can still drive the movable conical roller group to rotate and roll the ring, thereby improving the rolling efficiency.

[0014] 2. In this utility model, the power of the speed reduction motor after speed reduction and torque increase drives the second universal joint to rotate, thereby driving the connecting rod to rotate. Because the connecting rod and the sleeve have matching keyways, after the connecting rod drives the sleeve to rotate, it drives the connecting rod to rotate through the first universal joint. During the process of the height position of the cone roller changing, the sleeve slides along the outer groove of the connecting rod, thereby changing the length of the connecting rod and the sleeve. The power transmission route of the second universal joint, the connecting rod, the sleeve and the first universal joint still works normally. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a conical roller transmission system for a radial ring rolling mill, including a support 1, a fixed conical roller group 2, a movable conical roller group 3, and a reduction motor 5. A guide rail module 11 is fixedly connected inside the support 1. The movable conical roller group 3 is slidably connected to the support 1 via the guide rail module 11. The fixed conical roller group 2 is located directly below the movable conical roller group 3 and is fixedly installed inside the support 1. The reduction motor 5 is fixedly installed inside the support 1. The output shaft of the reduction motor 5 is driven by an adjustable transmission mechanism 4. The movable conical roller group 3 includes a conical roller body 31 and a roller seat 32. The adjustable transmission... Mechanism 4 includes an extension transmission assembly and an angle transmission assembly. The angle transmission assembly is connected to the conical roller body 31. The angle transmission assembly includes a spherical seat 41, rolling balls 46, a ball ring 47, an inner support seat 48, and a connecting rod 49. The end of the connecting rod 49 is fixedly installed in the middle of the inner support seat 48. Multiple sets of rolling balls 46 are distributed in a ring and are movably engaged in the outer grooves of the inner support seat 48. The ball ring 47 is movably engaged in the outer side of the multiple sets of rolling balls 46. The multiple sets of rolling balls 46 are movably connected in the inner groove of the spherical seat 41. The ball ring 47 is movably connected in the middle position between the inner support seat 48 and the spherical seat 41.

[0023] The specific settings and functions of this embodiment are described below: The fixed conical roller group 2 is located on the lower side of the annular part processing station, and the movable conical roller group 3 is located on the upper side of the annular part processing station. The height of the movable conical roller group 3 can be adjusted inside the bracket 1 via the guide rail module 11, and its position is locked by bolts. After the position of the movable conical roller group 3 is adjusted, the reduction motor 5 is started. The power of the reduction motor 5 after speed reduction and torque increase drives the connecting rod 49 to rotate through the extended transmission assembly. There is a ball 46 in each groove on the outer side of the inner support seat 48. Multiple sets of balls 46 are distributed in a ring in the holes of the ball ring 47. The ball ring 47 is located on the inner wall of the spherical seat 41, and the balls 46 are simultaneously stuck in the grooves inside the spherical seat 41. Therefore, after the connecting rod 49 drives the inner support seat 48 to rotate, the spherical seat is driven by the locking action of the balls 46. 41 rotates, and the spherical seat 41 drives the conical roller body 31 to rotate in the roller seat 32. The end of the conical roller body 31 processes the annular part. The structure of the fixed conical roller group 2 is the same as that of the movable conical roller group 3. The position of the fixed conical roller group 2 does not change. It is driven by a fixed position transmission method, such as belt transmission, so that the fixed conical roller group 2 also processes the annular part synchronously. During the process of the height position of the conical roller body 31 changing, the length of the extended transmission component changes. At the same time, the connecting rod 49 drives the inner support seat 48 to rotate a certain angle inside the spherical seat 41. The multiple sets of rolling balls 46 are always moving in the grooves of the inner support seat 48 and the spherical seat 41. Therefore, when the height position of the movable conical roller group 3 changes, the reduction motor 5 can still drive the movable conical roller group 3 to rotate and roll the ring, improving the ring rolling efficiency.

[0024] Example 2: Figure 1 - Figure 3 As shown, the extended transmission assembly includes a first universal joint 42, a sleeve 43, a connecting rod 44, and a second universal joint 45. The first universal joint 42 is fixedly connected to the other end of the connecting rod 49, and the other end of the first universal joint 42 is fixedly connected to the sleeve 43. The sleeve 43 is slidably engaged with the connecting rod 44 through a keyway. The second universal joint 45 is fixedly connected to the other end of the connecting rod 44 and is fixedly connected to the output shaft of the geared motor 5.

[0025] The overall effect of this embodiment is that the reduced speed and increased torque of the geared motor 5 drives the second universal joint 45 to rotate, thereby driving the connecting rod 44 to rotate. Since the connecting rod 44 and the sleeve 43 have matching keyways, after the connecting rod 44 drives the sleeve 43 to rotate, it drives the connecting rod 49 to rotate through the first universal joint 42. During the change of the height position of the cone roller 31, the sleeve 43 slides along the outer groove of the connecting rod 44, thereby changing the length of the connecting rod 44 and the sleeve 43. The power transmission route of the second universal joint 45, the connecting rod 44, the sleeve 43 and the first universal joint 42 still works normally.

[0026] The device is used and operates as follows: It is mounted on a ring rolling mill via a bracket 1, with the fixed conical roller group 2 positioned below the ring part processing station and the movable conical roller group 3 positioned above it. The movable conical roller group 3 can be adjusted in height within the bracket 1 via the guide rail module 11 and its position locked by bolts. After the movable conical roller group 3 is properly adjusted, the reduction motor 5 is started. The reduced speed and increased torque of the reduction motor 5 drive the second universal joint 45 to rotate, thereby driving the connecting rod 44 to rotate. Because the connecting rod 44 and the sleeve 43 have matching keyways, after the connecting rod 44 drives the sleeve 43 to rotate, it drives the connecting rod 49 to rotate via the first universal joint 42. Each groove on the outer side of the inner support seat 48 contains a ball 46. Multiple sets of balls 46 are distributed in a ring in the holes of the ball ring 47. The ball ring 47 is located on the inner wall of the spherical seat 41, while the balls 46 are simultaneously engaged in the grooves inside the spherical seat 41. Therefore, when the connecting rod 49 drives the inner support seat 48 to rotate, the ball 46 rotates. After the support 48 rotates, the ball bearing 46 engages and drives the spherical seat 41 to rotate. The spherical seat 41 drives the conical roller 31 to rotate in the roller seat 32. The end of the conical roller 31 processes the annular part. The structure of the fixed conical roller group 2 is the same as that of the movable conical roller group 3. The position of the fixed conical roller group 2 does not change. It is driven by a fixed position transmission method, such as belt transmission, so that the fixed conical roller group 2 also processes the annular part synchronously. During the change of the height position of the conical roller 31, the sleeve 43 slides along the outer groove of the connecting rod 44. As a result, the lengths of the connecting rod 44 and the sleeve 43 change. At the same time, the connecting rod 49 drives the inner support 48 to rotate a certain angle inside the spherical seat 41. The multiple sets of ball bearings 46 are always moving in the grooves of both the inner support 48 and the spherical seat 41. Therefore, when the height position of the movable conical roller group 3 changes, the reduction motor 5 can still drive the movable conical roller group 3 to rotate and roll the ring, improving the ring rolling efficiency.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
