Description

Technical Field

[0001] This utility model relates to the field of Mecanum wheel technology, and in particular to a Mecanum wheel robot adapted to large loads. Background Technology

[0002] A Mecanum wheel robot is a robot equipped with Mecanum wheels, which allow for omnidirectional movement and facilitate the transportation and placement of goods. However, a Mecanum wheel consists of a central wheel and multiple peripheral rollers arranged at angles. These rollers are typically connected to the Mecanum wheel body via connecting shafts. Due to the lack of support between the rollers and the Mecanum wheel robot's pivot, and the poor load-bearing capacity of the connecting shafts, Mecanum wheel robots are difficult to adapt to large loads.

[0003] Therefore, a Mecanum wheel robot adapted to large loads is needed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a Mecanum wheel robot that increases the load-bearing capacity of the Mecanum wheel by ensuring that the load-bearing shaft supports the rollers through a load-bearing shaft and a rotating wheel, while the rollers support each other through the rotating wheel. This robot is simple, efficient, safe, reliable, and easy to operate, making it suitable for large loads.

[0005] This utility model is achieved through the following technical solution: providing a Mecanum wheel robot adapted to large loads, including a Mecanum wheel hub; rollers are evenly arranged sequentially along the circumference of the hub, and the axes of the rollers are not in the same plane as the axis of the hub; a load-bearing shaft is coaxially connected to the hub, and a rotating wheel is coaxially rotated on the load-bearing shaft, with the side of the rotating wheel away from the load-bearing shaft in contact with the wheel surface of the roller; the load-bearing shaft and the rotating wheel ensure that the load-bearing shaft supports the rollers, and the rollers support each other through the rotating wheels, thereby increasing the load-bearing capacity of the Mecanum wheel.

[0006] As an optimization, a groove extending circumferentially along the roller and adapted to the roller surface is provided on the side of the swivel facing the roller; the groove increases the contact area between the swivel and the roller, thereby preventing the swivel from damaging the roller, and thus increasing the load-bearing capacity of the Mecanum wheel.

[0007] As an optimization, the roller is connected to the load-bearing shaft via a bearing, and the axes of the roller and the bearing are the same; the bearing reduces the friction between the load-bearing shaft and the roller, thereby reducing the friction between the roller and the roller.

[0008] As an optimization, the middle part of the wheel surface and the roller surface abut together; the wheel surface supports the main load-bearing surface of the roller through the wheel surface, thereby increasing the load-bearing capacity of the Mecanum wheel.

[0009] The beneficial effects of this utility model are as follows: the load-bearing shaft and the rotating wheel ensure that the load-bearing shaft supports the roller, and the rollers support each other through the rotating wheel, thereby increasing the load-bearing capacity of the Mecanum wheel; the groove increases the contact area between the rotating wheel and the roller, thereby preventing the rotating wheel from damaging the roller, and thus increasing the load-bearing capacity of the Mecanum wheel; the bearing reduces the friction between the load-bearing shaft and the rotating wheel, thereby reducing the friction between the roller and the rotating wheel; the rotating wheel supports the wheel surface that mainly bears the load of the roller, thereby increasing the load-bearing capacity of the Mecanum wheel.

[0017] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0018] like Figures 1-5 The Mecanum wheel robot of this invention, adapted to large loads, includes a Mecanum wheel hub 1; rollers 2 are evenly arranged in sequence along the circumference of the hub 1, and the axes of the rollers 2 are not parallel to the axis of the hub 1; a load-bearing shaft 3 is coaxially connected to the hub 1, and a rotating wheel 4 is coaxially rotated on the load-bearing shaft 3, with the side of the rotating wheel 4 away from the load-bearing shaft 3 in contact with the wheel surface of the rollers 2; the hubs 1 are arranged opposite each other, the rollers 2 are located between the two hubs 1, the load-bearing shaft 3 is fixedly connected to the hub 1, and the load-bearing shaft 3 is located between the two hubs 1; the load-bearing shaft 3 has a mounting groove adapted to the drive shaft of the Mecanum wheel robot; the rotating wheel 4 is located in the middle of the two hubs 1.

[0019] The Mecanum wheel is mounted on the drive shaft of the Mecanum wheel robot via the load-bearing shaft 3. When a large load is placed on the Mecanum wheel robot, the roller 2 at the bottom of the Mecanum wheel that is in contact with the ground is subjected to pressure. The roller 2 in contact with the ground transmits the pressure to the load-bearing shaft 3 and other rollers 2 through the rotating wheel 4, thus reducing the pressure on the individual roller 2. When the Mecanum wheel robot starts, the Mecanum wheel rotates. The roller 2 at the bottom of the Mecanum wheel that is in contact with the ground drives the rotating wheel 4 to rotate on the load-bearing shaft 3. At the same time, the rotating wheel 4 transmits the pressure on the roller 2 at the bottom of the Mecanum wheel that is in contact with the ground to the load-bearing shaft 3 and other rollers 2.

[0020] like Figures 1-4 The rotating wheel 4 shown has a groove 401 on the side facing the roller 2, which extends circumferentially along the roller 2 and is adapted to the wheel surface of the roller 2.

[0021] The Mecanum wheel robot starts, the Mecanum wheel rotates, and the roller 2 at the bottom of the Mecanum wheel, which is in contact with the ground, rolls in the groove 401 and drives the rotating wheel 4 to rotate on the load-bearing shaft 3.

[0022] like Figures 1-3 The rotating wheel 4 shown is connected to the load-bearing shaft 3 through a bearing, and the axes of the rotating wheel 4 and the bearing are the same.

[0023] The rotating wheel 4 rotates on the load-bearing shaft 3 via bearings.

[0024] like Figures 1-4 The middle part of the surfaces of the rotating wheel 4 and the roller 2 are in contact.

[0025] The roller 4 supports the main load-bearing surface of the roller 2; the roller 2, whose bottom is in contact with the ground, rotates, and the roller 2 drives the roller 4 to rotate. At the same time, the main load-bearing surface of the roller 2 is always connected to the rotation.

[0026] In actual production, the Mecanum wheel is mounted on the drive shaft of the Mecanum wheel robot via the load-bearing shaft 3. After a large load is placed on the Mecanum wheel robot, the roller 2 at the bottom of the Mecanum wheel that is in contact with the ground is subjected to pressure. The roller 2 in contact with the ground transmits the pressure to the load-bearing shaft 3 and other rollers 2 through the rotating wheel 4, thus reducing the pressure on a single roller 2. When the Mecanum wheel robot starts, the Mecanum wheel rotates. The roller 2 at the bottom of the Mecanum wheel that is in contact with the ground drives the rotating wheel 4 to rotate on the load-bearing shaft 3. At the same time, the rotating wheel 4 transmits the pressure on the roller 2 at the bottom of the Mecanum wheel that is in contact with the ground to the load-bearing shaft 3 and other rollers 2.
