Description

Technical Field

[0001] This utility model belongs to the field of tooling structure technology, and relates to a tooling structure for installing external rollers. Background Technology

[0002] External rollers, typically referring to externally mounted electric rollers, are a new type of drive device where the motor is installed outside the roller body, and the reduction gear is built into the electric roller. The working principle of an external roller is that the motor runs outside the roller, and the power generated by the motor's output shaft is transmitted through a coupling (or coupler) into the electric roller, then drives the roller body to rotate through the reduction mechanism, thereby driving the conveyor belt to rotate. In existing technology, the motor output shaft and the electric roller are connected by a flange. To facilitate motor installation, a base is usually set at one end of the electric roller to mount the motor, thus connecting the motor output shaft to the electric roller. External rollers, with their unique design structure and superior performance, have been widely used in many industrial fields. However, despite the many advantages of external rollers, such as high transmission efficiency and compact structure, there are still many problems to be solved in terms of installation and maintenance during practical applications.

[0003] First, space constraints are a major challenge in the installation of external rollers. Since the motor is mounted outside the roller, it places higher demands on installation space. In many industrial sites or benchtop testing environments, the connection between the motor and the roller is often difficult to access due to limited space, causing significant inconvenience for maintenance. Maintenance personnel must spend more time and effort overcoming space limitations during routine inspections or troubleshooting, which not only increases the difficulty of maintenance but also raises maintenance costs. Second, the difficulty of disassembling the motor in an external roller is a significant drawback of its installation structure. The motor and roller are usually connected by complex connections and fixing structures, which often prioritize the stability of the connection while neglecting the ease of disassembly. When maintenance or replacement of the motor is needed, the disassembly process can become extremely cumbersome, even requiring special tools or equipment. This not only prolongs maintenance time but may also cause potential damage to other parts of the equipment. Furthermore, the installation method of external roller motors may also increase initial investment costs. To ensure that the motor can be stably and reliably mounted outside the roller, more complex installation structures (such as a separate base for the motor) and more advanced motor models may be required. These additional design and material selections will undoubtedly increase the manufacturing cost of the equipment, thereby driving up the initial investment of the entire project.

[0004] In summary, external rollers still present many unresolved issues in terms of installation and maintenance. Therefore, it is necessary to provide a novel tooling structure for installing external rollers to address the problems of space limitations, inconvenient disassembly, and high initial investment costs in existing technologies. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a tooling structure for installing an external roller, so as to install the motor in the external roller without using a base.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tooling structure for installing an external roller includes fixed seats arranged at both ends of the roller, wherein the roller is rotatably connected to the fixed seats;

[0008] It also includes a fixed end fixedly connected to one of the fixed seats, and a motor base plate is connected to the side of the fixed end away from the roller, the motor base plate being used to mount the motor;

[0009] A tie rod is provided between the motor base plate and the fixed end. One end of the tie rod is connected to the end of the motor base plate away from the fixed end, and the other end is connected to the top of the fixed end, forming a diagonal tie structure.

[0010] Furthermore, a pressure plate is provided on the motor base plate for fixing the motor to the motor base plate.

[0011] Furthermore, there are at least four pressure plates, which press down on the four corners of the motor respectively; each pressure plate is provided with at least two bolt holes, and the pressure plate is locked to the motor base plate and pressed down on the motor base by bolts.

[0012] Furthermore, the fixed end is in the shape of an inverted L-shape and has several bolt holes thereon, so as to be fixedly connected to the fixed seat and the motor base plate by bolts respectively;

[0013] The motor base plate has an overall L-shaped structure that flips to the left, and has several bolt holes on it for fixing to the fixed end and the pressure plate by bolts.

[0014] Furthermore, the bottom of the motor base plate is provided with reinforcing ribs to increase the strength of the motor base plate.

[0015] Furthermore, the roller is rotatably connected to the fixed base via a bearing, and the bearing is mounted on the fixed base via a bearing seat.

[0016] Furthermore, the output shaft of the motor is connected to the input shaft of the drum via a flange or coupling; the bearing housing and the fixed seat are fixedly connected by bolts.

[0017] Furthermore, a slotted hole is provided at the connection between the pull rod and the fixed end for adjusting the tension of the pull rod on the motor base plate.

[0018] Furthermore, a pad is provided between the motor and the motor base plate, and a pad is also provided between the bearing seat and the fixed seat. By adjusting the thickness of the pad, the motor output shaft and the roller input shaft are kept on the same horizontal plane.

[0019] Furthermore, the connection surface between the motor base plate and the fixed end is provided with vertically arranged guide blocks, and the fixed end is provided with guide grooves that match the guide blocks to form a guiding and positioning structure.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. Structural optimization and ease of installation:

[0022] This invention achieves baseless installation of the motor on an external roller through an innovative inclined bracing structure and modular design. The core solution employs an L-shaped combination structure of the fixed end and the motor base plate, along with an inclined bracing support system formed by tie rods, significantly simplifying the complex base system required for traditional roller motor installation. The motor base plate is directly and rigidly connected to the fixed end, and the motor is secured by multi-point locking with pressure plates, ensuring installation stability while avoiding the space occupation and cost issues associated with an additional base. Furthermore, the L-shaped design of the motor base plate and the bottom reinforcing ribs further enhance overall rigidity, ensuring reliable motor operation under high load conditions.

[0023] 2. Improved adjustment accuracy and stability:

[0024] The technical solution incorporates adjustable functional modules at key connection points: the tie rod and fixed end are connected via a slotted hole, allowing dynamic adjustment of the tie rod tension to compensate for installation errors and enhance vibration resistance; replaceable shims of varying thickness are added below the motor and bearing housing, enabling high-precision alignment of the motor output shaft and roller input shaft by adjusting the shim thickness, effectively eliminating wear problems caused by axial misalignment. Furthermore, the cooperative design of the guide block and guide groove allows for quick positioning of the motor base plate and fixed end during installation, reducing manual adjustment time and improving assembly efficiency. These innovations collectively ensure the long-term stability and transmission accuracy of the equipment.

[0025] 3. Practicality and economical maintenance

[0026] The solution incorporates numerous practical and innovative design details: the pressure plate employs at least four independent locking points, coupled with a double-bolt hole structure, to create a uniform clamping force on the motor base, preventing localized stress concentration; all connecting components are secured with standardized bolts, facilitating disassembly, maintenance, or component replacement. Compared to traditional welding or integral casting processes, this tooling structure offers advantages such as reusability, strong adaptability, and low modification costs. The overall solution is not only suitable for various drum motor installation scenarios but can also be rapidly expanded in functionality through modular combinations, demonstrating significant industrial application value and economic benefits.
