[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example:

[0020] Please see Figure 1-3A blunt gear drive device for a bogie furnace includes a base 1, a motor assembly 2 mounted on one side of the base 1, a pinion 3 mounted on the output shaft of the motor assembly 2, a fixed support 101 on the top surface of the base 1, a movable shaft 4 rotatably connected to the fixed support 101, a large gear 5 sleeved on one end of the movable shaft 4, the pinion 3 meshing with the large gear 5, a blunt gear 6 sleeved in the middle of the movable shaft 4, and a pin rack assembly 9 meshing above the blunt gear 6, the pin rack assembly 9 being installed at the bottom of the bogie furnace; the motor assembly 2 drives the pinion 3 to rotate, the pinion 3 drives the large gear 5 and the movable shaft 4 to rotate, thereby causing the blunt gear 6 located on the movable shaft 4 to rotate, and the blunt gear 5 then pushes the pin rack assembly 9, which is installed below the bogie furnace frame and meshes with the blunt gear 5, to move linearly, thereby causing the bogie to enter or exit the furnace chamber. This transmission method has advantages such as simple structure, reliable operation, accurate bogie positioning, and convenient maintenance.

[0021] Both the large gear 5 and the blunt gear 6 are connected to the movable shaft 4 via key 7, enabling them to rotate coaxially with the shaft 4. Keyways matching key 7 are machined into the inner bores of the large gear 5 and the blunt gear 6, as well as at the corresponding mounting positions on the movable shaft 4, to ensure that key 7 can be tightly embedded without loosening. The key 7 installed inside the large gear 5 and the blunt gear 6 can be of different sizes as needed.

[0022] In this application, a motor and a reducer are used as the power source. The motor reduces speed and increases torque through the reducer, providing a stable driving force for the entire transmission system. The pinion is directly driven by the reducer and forms a gear transmission ratio with the large gear, further adjusting the speed and torque to adapt to subsequent transmission requirements. By adjusting the transmission ratio and motor power, different load and speed requirements can be adapted.

[0023] In this application, spacers 8 are provided on both sides of the blunt gear 6. The spacers 8 can rotate with the movable shaft 4 and are used to limit the movement of the blunt gear 6. The spacers 8 are made of wear-resistant and high-strength material, have a compact structure, and are internally machined with holes that match the movable shaft 4 so that they can be tightly fitted onto the movable shaft 4. The main function of the spacers 8 is to restrict the axial movement of the blunt gear 6 on the movable shaft 4, ensuring that the blunt gear 6 will not deviate or fall off when transmitting torque, thereby maintaining the stability and safety of the transmission system.

[0024] In this application, a retaining ring A10 is provided on the outer side of the large gear 5. The retaining ring A10 is connected to the end of the movable shaft 4 by a bolt A11. The retaining ring A10 limits the end of the large gear 5 to prevent the large gear 5 from falling off the movable shaft 4, thus ensuring the stability and safety of the large gear 5 when transmitting torque. At the same time, the connection method of the bolt A11 is convenient for disassembly. When it is necessary to replace or repair the large gear 5, the bolt A11 and the retaining ring A10 can be easily removed, thereby realizing the quick disassembly of the large gear 5.

[0025] In this application, a sliding bearing 12 is installed on the outer side of the spacer 8 of the movable shaft 4. The outer wall of the sliding bearing 12 is mounted on the fixed support 101. The sliding bearing 12 provides stable support and guidance for the rotation of the movable shaft 4. The main function of the sliding bearing 12 is to provide stable support and guidance for the movable shaft 4, ensuring that the movable shaft 4 will not deviate or wobble during rotation. With the support of the sliding bearing 12, the movable shaft 4 can maintain a stable rotation trajectory, thereby improving the stability and reliability of the transmission system.

[0026] The fixed support 101 is provided with a fixing member for fixing the sliding bearing 12. The fixing member has a groove, and the outer wall of the sliding bearing 12 extends into the groove. The two ends of the fixing member are fixed to the fixed support 101 by bolts B14, bolts C15 and nuts 16 respectively. The installation position of the sliding bearing 12 is fixed by the fixed support 101 and the fixing member, while making the sliding bearing 12 detachable.

[0027] In this application, the motor assembly 2 includes a motor and a reducer. The motor is connected to the reducer, and a pinion 3 is mounted on the output shaft of the reducer. A retaining ring B13 is provided on the outer side of the pinion 3, and the retaining ring B13 is connected to the output shaft of the reducer by bolts B14. The pinion 3 is fixed to the output shaft of the reducer by means of key connection, spline connection, or set screws to ensure that it will not fall off or loosen when transmitting power. In order to prevent the pinion 3 from falling off the output shaft of the reducer when transmitting power, and to protect the pinion 3 and the output shaft of the reducer from interference from external factors, a retaining ring B13 is provided on the outer side of the pinion 3.

[0028] The bogie furnace structure includes a movable bogie with a traveling mechanism at the bottom. A pinion and rack assembly 9 is installed at the bottom of the bogie. The drive device of this application, in conjunction with the pinion and rack assembly 9, enables the bogie to move forward and backward. This improves work efficiency and ensures the accuracy and stability of the heating process.

[0029] The pin and rack assembly 9 includes a base plate located at the bottom of the trolley, with a rib plate and a clamping plate on the bottom surface of the base plate. The pin and rack are located at the end of the clamping plate and mesh with the blunt gear 6.

[0030] Working principle:

[0031] In use, the motor drives the small gear 3 to rotate via a reducer. The small gear 3 meshes with the large gear 5, transmitting torque to the large gear 5. Since the large gear 5 is securely connected to the movable shaft 4 via a key 7, its rotation causes the movable shaft 4 to rotate synchronously. Simultaneously, the blunt gear 6 is also connected to the movable shaft 4 via a key 7, so when the movable shaft 4 rotates, the blunt gear 6 also rotates synchronously. The rotation of the blunt gear 6 then pushes the pin rack meshing with it to move linearly, thus realizing the trolley's entry and exit movements. The transmission mechanism composed of the motor, reducer, small gear 3, and large gear 5 drives the blunt gear 6 to rotate, which in turn pushes the pin rack installed below the trolley frame and meshing with it to move linearly, thereby allowing the trolley to enter or exit the furnace. This transmission method has advantages such as simple structure, reliable operation, accurate trolley positioning, and convenient maintenance. The bogie furnace structure includes a movable bogie with a walking mechanism at the bottom. The drive mechanism of this application enables the bogie to be pulled out or into the furnace along the ground rails, realizing the bogie's entry and exit actions, which facilitates loading and unloading of objects outside the furnace.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
