[0002] A leveling machine (also known as a screed or leveling machine tool) is a mechanical device used for processing sheet metal. It is primarily used to level uneven or wavy sheet metal, making its surface smooth and uniform. This equipment is widely used in metal processing fields such as steel, aluminum, and copper, especially for leveling sheet metal before rolling, shearing, and cutting processes to ensure accuracy and quality in subsequent processing. The pressure roller drive structure of existing leveling machines typically consists of a bearing housing directly connected to a geared motor.

[0003] In the existing drive structure, the main shaft of the geared motor is prone to breakage during use, resulting in frequent replacement of the geared motor. This reduces the stability of the leveling machine, shortens the service life of the geared motor, and affects the production schedule. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a drive structure for a leveling machine, thereby improving the working stability of the leveling machine and extending the service life of the geared motor.

[0005] In view of this, the present invention provides a drive structure for a leveling machine, comprising:

[0006] A motor mounting plate, on which a geared motor is mounted;

[0007] The motor spindle is mounted on the drive end of the geared motor.

[0011] A drive sprocket is located at the end of the motor countershaft away from the geared motor.

[0012] The motor subshaft is mounted on a bearing housing via a bearing.

[0013] In this technical solution, when the drive structure is working, the geared motor drives the motor main shaft to rotate, which in turn drives the motor secondary shaft to rotate through the universal joint. The sprocket on the motor secondary shaft drives the gears on other pressure rollers to rotate, thereby realizing the rotation of the upper and lower pressure rollers to achieve the purpose of leveling the material. By setting the bearing seat assembly to form a double bearing seat mode, the stress on the geared motor is reduced, thereby preventing the breakage of the main shaft and secondary shaft of the geared motor, increasing the service life of the geared motor, and improving the working stability of the leveling machine.

[0014] Furthermore, the above technical solution also includes:

[0015] A reinforcing shaft is disposed on the surface of the motor auxiliary shaft, and the axial direction of the reinforcing shaft is parallel to the axial direction of the motor auxiliary shaft;

[0016] The reinforcing shaft has several of them and is evenly spaced along the circumference of the motor sub-shaft.

[0017] In the above technical solution, the reinforcing shaft further includes:

[0018] A shaft mounting base, wherein two shaft mounting bases are symmetrically distributed along the axial direction of the motor secondary shaft, and the shaft mounting bases are provided with shaft through holes;

[0019] The shaft body has threads at both ends, and the two ends of the shaft body are respectively inserted into two shaft through holes;

[0020] The shaft body is fixed to the shaft mounting base by a nut that engages with the threaded end of the shaft body.

[0021] In the above technical solution, the nut further includes:

[0022] The first nut has a plurality of teeth on one side surface, the plurality of teeth being evenly spaced along the circumference of the first nut, and the inner diameter of the plurality of teeth being larger than the diameter of the screw hole of the first nut.

[0023] The second nut has a pressing groove on the surface of the side opposite to the first nut, and the pressing groove is in the shape of a frustum of a cone.

[0024] The extrusion groove engages with several teeth, and when the first nut and the second nut are screwed into the end of the shaft body, the teeth can tilt towards the thread at the end of the shaft body under the extrusion of the extrusion groove.

[0025] In the above technical solution, the shaft body further includes:

[0026] A chromium-reinforced layer is disposed on the surface of the shaft body;

[0027] A tungsten carbide layer is disposed on the surface of a chromium-reinforced layer;

[0028] A reinforced inner core is provided inside the shaft body.

[0029] The beneficial effects of this utility model are:

[0030] 1. By setting up a double bearing housing, the stress on the geared motor is reduced, thereby preventing the main shaft and auxiliary shaft of the geared motor from breaking, increasing the service life of the geared motor, and improving the working stability of the leveling machine.

[0031] 2. By reinforcing the shaft, the stress on the motor's secondary shaft is shared, further reducing the likelihood of the secondary shaft breaking, increasing the service life of the geared motor, and improving the working stability of the leveling machine. At the same time, the nut prevents the reinforcing shaft from loosening and falling off.

[0032] 3. The addition of a chromium-reinforced layer, a tungsten carbide layer, and a reinforced inner core further enhances the structural strength of the shaft body, reduces the likelihood of shaft breakage, increases the service life of the geared motor, and improves the working stability of the leveling machine.

[0043] Example 1:

[0044] This application provides a drive structure for a leveling machine, including: a motor mounting plate 1, on which a geared motor 2 is mounted; and a motor spindle 3, which is mounted on the drive end of the geared motor 2.

[0045] It also includes: a motor subshaft 4, which is connected to the motor main shaft 3 via a universal joint 5; a bearing housing assembly 6, which includes two bearing housings arranged side by side along the axial direction of the motor subshaft 4; and a transmission sprocket 7, which is located at the end of the motor subshaft 4 away from the geared motor 2.

[0046] Among them, the motor subshaft 4 is mounted on the bearing housing 6 through a bearing.

[0047] In this embodiment, when the drive structure is working, the geared motor 2 drives the motor main shaft 3 to rotate, which in turn drives the motor secondary shaft 4 to rotate through the universal joint 5. The sprocket on the motor secondary shaft 4 drives the gears on other pressure rollers to rotate, thereby achieving the purpose of leveling the material by rotating the upper and lower pressure rollers. The bearing seat group 6 is set to form a double bearing seat mode to reduce the force on the geared motor 2, thereby preventing the main shaft and secondary shaft of the geared motor 2 from breaking, increasing the service life of the geared motor 2, and improving the working stability of the leveling machine.

[0048] Example 2:

[0049] This embodiment provides a drive structure for a leveling machine. In addition to the technical solutions of the above embodiments, it also has the following technical features, including: a reinforcing shaft 8, which is disposed on the surface of the motor sub-shaft 4, and the axial direction of the reinforcing shaft 8 is parallel to the axial direction of the motor sub-shaft 4.

[0050] Among them, the reinforcing shaft 8 has several that are evenly spaced along the circumference of the motor sub-shaft 4.

[0051] The reinforcing shaft 8 also includes: a shaft mounting base 80, which has two shaft mounting bases symmetrically distributed along the axial direction of the motor auxiliary shaft 4, and a shaft through hole is provided on the shaft mounting base 80; a shaft body 81, which has threads at both ends, and the two ends of the shaft body 81 are respectively inserted into the two shaft through holes;

[0052] The shaft body 81 is fixed to the shaft mounting base 80 by a nut and a threaded connection at the end of the shaft body 81.

[0053] In this embodiment, by setting the reinforcing shaft 8, the reinforcing shaft 8 can effectively disperse the external force on the motor subshaft 4 during operation, thereby improving the structural strength and load-bearing performance of the motor subshaft 4 and reducing the occurrence of breakage. At the same time, since the reinforcing shaft 8 is installed on the outside of the motor subshaft 4, the reinforcing shaft 8 can also protect the motor subshaft 4 from external impacts to a certain extent, preventing external impacts from damaging the motor subshaft 4. Compared with the prior art, this utility model further improves the service life of the geared motor 2 and improves the working stability of the leveling machine.

[0054] Example 3:

[0055] This embodiment provides a drive structure for a leveling machine. In addition to the technical solutions of the above embodiments, it also has the following technical features: the nut further includes: a first nut 82, one side surface of the first nut 82 is provided with a plurality of teeth 84, the plurality of teeth 84 are evenly spaced along the circumference of the first nut 82, and the inner diameter of the plurality of teeth 84 is larger than the diameter of the screw hole of the first nut 82; a second nut 83, the surface of the second nut 83 opposite to the first nut 82 is provided with a pressing groove 85, the pressing groove 85 is shaped like a frustum cone;

[0056] The pressing groove 85 cooperates with several clamping teeth 84. When the first nut 82 and the second nut 83 are screwed into the end of the shaft body 81, the clamping teeth 84 can tilt towards the thread at the end of the shaft body 81 under the pressing of the pressing groove 85.

[0057] In this embodiment, during the installation of the reinforcing shaft 8, after the two ends of the shaft body 81 are passed through the two shaft through holes respectively, the nuts are tightened on the ends of the shaft body 81. The first nut 82 is screwed into the end of the shaft body 81 first, and then the second nut 83 is screwed in. During the tightening of the second nut 83, the extrusion groove 85 extrudes the clamping tooth 84. After being extruded, the clamping tooth 84 tilts and bends towards the thread at the end of the shaft body 81, and finally abuts against the thread surface, thereby preventing the first nut 82 from loosening and falling outward, and thus preventing the shaft body 81 from falling off.
