Description

Technical Field

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

[0002] The transmission system is the core mechanism in the radial ring rolling mill used to drive the main rolls and transmit power.

[0003] However, in the existing technology, the traditional main roll drive system has certain shortcomings in terms of lubrication and component fixing. For example, it is inconvenient to replenish the lubricant, which may lead to faster wear of the transmission components, affecting the service life and working efficiency of the equipment. The fixing method of components such as storage tanks is complicated, which is not convenient for quick installation and disassembly, increasing maintenance costs and time. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of inconvenient lubrication and complex component fixing in the existing technology, and to propose a main roll drive system for a radial ring rolling mill.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a main roll transmission system for a radial ring rolling mill, comprising a base, a top cover fixedly connected to the top of the base by bolts, a lubricant replenishment mechanism fixedly installed on the inclined surface of the top cover, the lubricant replenishment mechanism comprising a positioning block and a storage tank, a filling head fixedly installed at one end of the storage tank, the filling head being inserted into the interior of the positioning block, the positioning block being fixedly installed on the upper surface of the top cover, and a through hole being provided at the junction of the top cover and the positioning block.

[0006] Preferably, a first gear and a second gear are rotatably mounted inside the base, and the first gear and the second gear are meshed together.

[0007] Preferably, an input shaft is fixedly connected to one side of the first gear, and an output shaft is fixedly connected to one side of the second gear. Limiting plates are fixedly installed on the rods of both the input shaft and the output shaft.

[0008] Preferably, a clamping plate is rotatably connected to the upper surface of the positioning block. The clamping plate is located on both sides of the storage tank. A limit groove is opened on the tank body of the storage tank. A protrusion with a shape that matches the limit groove is fixedly installed on the inner side wall of the clamping plate.

[0009] Preferably, a protrusion is fixedly installed on the upper surface of the positioning block, and the protrusion is located at the corner of the clamping plate.

[0010] Preferably, a connecting rod is fixedly installed at the corner of the clamping plate, and the connecting rod is rotatably connected to the protrusion.

[0011] Preferably, a torsion spring is fixedly connected between the clamping plate and the protrusion, and the torsion spring is sleeved on the outside of the connecting rod.

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

[0013] 1. In this utility model, by setting a lubricant replenishment mechanism on the top cover, the lubricant in the storage tank can be delivered to the corresponding part of the transmission system through the filling head and the through hole at the junction of the positioning block and the top cover to lubricate the transmission components such as gears, reduce friction and wear, reduce energy loss, and extend the service life of the transmission system. The transmission system transmits power through gear meshing, with accurate transmission ratio and high transmission efficiency, which can ensure the stable and reliable operation of the main roll.

[0014] 2. In this utility model, the protrusion on the inner side wall of the clamping plate is adapted to the limiting groove of the storage tank body. The elastic force provided by the torsion spring allows the protrusion to be inserted into the limiting groove, thereby firmly fixing the storage tank on the positioning block. When it is necessary to remove the storage tank, the clamping plate is rotated to overcome the elastic force of the torsion spring, so that the protrusion is disengaged from the limiting groove, and the storage tank can be easily removed.

[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 2 , Figure 3 and Figure 4 As shown, this utility model provides a main roll transmission system for a radial ring rolling mill, including a base 1. A top cover 2 is fixedly connected to the top of the base 1 by bolts. A lubricant replenishment mechanism 3 is fixedly installed on the inclined surface of the top cover 2. The lubricant replenishment mechanism 3 includes a positioning block 31 and a storage tank 32. A filling head 34 is fixedly installed at one end of the storage tank 32. The filling head 34 is inserted into the inside of the positioning block 31. The positioning block 31 is fixedly installed on the upper surface of the top cover 2. A through hole 9 is opened at the junction of the top cover 2 and the positioning block 31. A first gear 5 and a second gear 7 are rotatably installed inside the base 1. The first gear 5 and the second gear 7 are meshed. An input shaft 4 is fixedly connected to one side of the first gear 5. An output shaft 8 is fixedly connected to one side of the second gear 7. Limit plates 6 are fixedly installed on the rods of the input shaft 4 and the output shaft 8.

[0023] The specific settings and functions of this embodiment are described below. The input shaft 4 drives the first gear 5 to rotate, and the first gear 5 meshes with the second gear 7, thereby transmitting power to the second gear 7, which in turn drives the output shaft 8 to rotate, realizing the transmission of the main roller. The limiting plate 6 is fixedly installed on the rods of the input shaft 4 and the output shaft 8, which can limit the shaft and prevent axial movement during rotation, ensuring the stability of the transmission system. In the lubricating fluid replenishment mechanism 3, the lubricating fluid in the storage tank 32 can be delivered to the corresponding parts of the transmission system through the filling head 34 and the through hole 9 at the junction of the positioning block 31 and the top cover 2, lubricating the gears and other transmission components, reducing friction and wear, reducing energy loss, and extending the service life of the transmission system. The system transmits power through gear meshing, with accurate transmission ratio and high transmission efficiency, ensuring stable and reliable operation of the main roll. The setting of the limit plate 6 effectively restricts the axial movement of the input shaft 4 and the output shaft 8, improving the installation accuracy of the shafts and the stability of the transmission system, avoiding problems such as poor gear meshing caused by shaft movement, and ensuring the normal operation of the transmission system. The design of the lubricating fluid replenishment mechanism 3 facilitates timely replenishment of lubricating fluid to the transmission system, which can effectively reduce friction between transmission components, reduce heat generation and wear, improve the reliability and durability of the transmission system, and at the same time reduce maintenance workload and maintenance costs. The top cover 2 is fixedly connected to the base 1 by bolts, which is convenient for installation and disassembly, and facilitates internal inspection and maintenance of the transmission system.

[0024] Example 2: Figure 3and Figure 4 As shown, a clamping plate 33 is rotatably connected to the upper surface of the positioning block 31. A limit groove 35 is provided on the tank body of the storage tank 32. A protrusion with a shape that matches the limit groove 35 is fixedly installed on the inner side wall of the clamping plate 33. A protrusion 38 is fixedly installed on the upper surface of the positioning block 31. The protrusion 38 is located at the corner of the clamping plate 33. A connecting rod 36 is fixedly installed at the corner of the clamping plate 33. The connecting rod 36 is rotatably connected to the protrusion 38. A torsion spring 37 is fixedly connected between the clamping plate 33 and the protrusion 38. The torsion spring 37 is sleeved on the outside of the connecting rod 36.

[0025] The overall effect of this embodiment is that the clamping plate 33 is rotatably connected to the protrusion 38 via the connecting rod 36, and the torsion spring 37 is sleeved on the outside of the connecting rod 36, so that the clamping plate 33 maintains a tendency to clamp the storage tank 32 when no external force is applied. When the storage tank 32 is placed on the positioning block 31, the protrusion on the inner side wall of the clamping plate 33 is adapted to the limiting groove 35 of the storage tank 32, and the elastic force provided by the torsion spring 37 causes the protrusion to engage with the limiting groove 35, thereby firmly fixing the storage tank 32 on the positioning block 31. When it is necessary to remove the storage tank 32, the clamping plate 33 is rotated to overcome the torsion spring. The elastic force of spring 37 allows the protrusion to disengage from the limiting groove 35, making it easy to remove the storage tank 32. Through the cooperation of clamping plate 33, protrusion, limiting groove 35, protrusion 38, connecting rod 36 and torsion spring 37, the storage tank 32 can be quickly installed and removed. Compared with traditional fixing methods, the operation is simple and quick, requiring no complicated tools. The continuous clamping force provided by torsion spring 37 ensures that the storage tank 32 is stable and does not loosen during equipment operation, ensuring the stable operation of the lubricant replenishment mechanism 3. At the same time, this reusable fixing method facilitates the replacement and maintenance of the storage tank 32, reducing equipment operating costs.

[0026] The operating method and working principle of this device are as follows: The main roll drive system of the radial ring rolling mill works as follows: First, the equipment is installed. The base 1 and the top cover 2 are fixedly connected by bolts to form the basic frame of the drive system. The lubricant replenishment mechanism 3 is installed on the inclined surface of the top cover 2. The storage tank 32 is placed on the positioning block 31. The storage tank 32 is fixed by the fit between the inner protrusion of the clamping plate 33 and the limiting groove 35 of the storage tank 32, as well as the elastic force of the torsion spring 37. The filling head 34 is inserted into the positioning block 31, and lubrication is provided to the transmission components through the through hole 9. When the equipment is started, the input shaft 4 rotates. The first gear 5 meshes with the second gear 7 to transmit power, thereby driving the output shaft 8 to rotate and realize the main roll transmission. During operation, the limiting plate 6 restricts the axial movement of the input shaft 4 and the output shaft 8 to ensure transmission stability. The lubricating fluid in the storage tank 32 lubricates the gears and other components through the filling head 34 and the through hole 9, reducing friction and wear. When maintenance or replacement of the storage tank 32 is required, the clamping plate 33 is rotated to overcome the spring force of the torsion spring 37, causing the convex strip to disengage from the limiting groove 35, and the storage tank 32 can be removed. After maintenance or replacement, it is re-fixed according to the installation steps to continue to ensure the normal operation of the transmission system.

[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.
