Technical Field
[0001] This utility model relates to the field of servo motor end cover technology, and more specifically, to a reinforced end cover for a high-torque servo motor in heavy-duty AGVs. Background Technology
[0002] With the rapid development of the automated logistics industry, heavy-duty AGVs (Automated Guided Vehicles) are increasingly widely used in industrial production and logistics transportation. Heavy-duty AGVs require high load-bearing capacity and precise motion control capabilities, which places higher demands on the high-torque servo motors in their drive systems. During the operation of these high-torque servo motors, the motor end cover plays a crucial role. It must not only protect the internal windings, rotor, and other components of the motor from external dust, moisture, and foreign objects, but also withstand the vibrations and torque generated during motor operation, ensuring the motor's stability and reliability.
[0003] Traditional end caps have limited strength and stability, making it difficult to withstand the large vibrations and torques generated during heavy-duty AGV operation. They are prone to loosening and deformation, which can affect the normal operation of the motor. At the same time, high-torque servo motors generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, the motor temperature will rise, affecting the motor's performance and efficiency, and may even cause motor failure. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a reinforced end cover for a high-torque servo motor of a heavy-duty AGV to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforced end cover for a high-torque servo motor of a heavy-duty AGV, comprising a servo motor housing and an end cover located on one side of the servo motor housing. A connecting ring is fixedly connected to the side of the end cover near the servo motor housing. A first positioning groove is formed around the circumference of the connecting ring, and a sealing ring is provided at one end of the connecting ring. An annular groove is formed on the inner side of the end of the servo motor housing near the end cover. A positioning block is fixedly connected to the inner cavity of the annular groove. The cooperation between the positioning block and the first positioning groove facilitates positioning during installation, prevents the end cover from rotating in the circumferential direction, and improves the stability of the connection. The sealing ring is squeezed by the connecting ring located inside the annular groove, which enhances the sealing between the end cover and the servo motor housing and prevents dust, moisture, etc. from entering the motor from the connection point.
[0006] The servo motor housing and the end cover are symmetrically fixedly connected to a plurality of second connecting lugs and a first connecting lug on one side. Two reinforcing inclined plates are fixedly connected to one side of the first connecting lug. The end cover and the servo motor housing can be firmly connected by bolts. The reinforcing inclined plates can enhance the structural strength of the first connecting lug, enabling it to withstand greater tension and torque, and further improve the reliability of the connection between the end cover and the servo motor housing.
[0007] The end cap has a first support ring, a reinforcing ring, and a reinforcing rib fixedly connected to its center.

The anti-collision ring can protect the end cap, prevent the end cap from being damaged when it is hit by external force, further enhance the structural strength of the end cap, and improve the overall stability of the end cap.
[0013] Preferably, the anti-collision ring, the second support ring, the reinforcing rod, the heat dissipation cylinder, the reinforcing rib, the reinforcing ring, the first support ring, and the connecting ring are all integrally cast with the end cover, which improves the overall strength and rigidity of the end cover, enabling it to withstand the large vibrations and torques generated during the operation of the heavy-duty AGV, and ensuring the stability and reliability of the motor.
