Description

Technical Field

[0001] The utility model relates to the technical field of mechanical installation, in particular to a Mecanum wheel small roller installation structure. Background Art

[0002] The Mecanum wheel is an omnidirectional wheel invented by the Swedish Mecanum company. This omnidirectional movement is based on the principle of a central wheel with many axles located around the wheel. These angled peripheral axles convert part of the wheel steering force into a wheel normal force.

[0003] However, the existing Mecanum wheel small rollers on the market do not have an adjustment function during the installation process, and are not convenient to install, resulting in low installation efficiency and affecting production efficiency. Therefore, a Mecanum wheel small roller installation structure is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a Mecanum wheel small roller installation structure, which has the advantages of being easy to adjust and install and having a lubricating effect, thereby solving the problem that ordinary small rollers are inconvenient to install.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a Mecanum wheel small roller installation structure, comprising a Mecanum wheel body, a small roller body is arranged inside the Mecanum wheel body, and an adjustment and lubrication installation device is arranged outside the small roller body;

[0006] The regulating and lubricating installation device comprises a cylindrical roller bearing, a hollow shaft, a first threaded ring, a protective block, a wheel body, a rotating shaft, an arc block and a bolt. The cylindrical roller bearing is arranged inside the small roller body, the hollow shaft is arranged outside the cylindrical roller bearing, the first threaded ring is arranged outside the hollow shaft, the protective block is arranged outside the hollow shaft, the wheel body is arranged outside the Mecanum wheel body, the wheel body is rotatably connected inside the wheel body, the arc block is fixedly installed outside the rotating shaft, and the arc block is arranged outside the bolt.

[0012] Beneficial Effects

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 A Mecanum wheel small roller installation structure includes a Mecanum wheel body 1, a small roller body 2 is arranged inside the Mecanum wheel body 1, and an adjustment and lubrication installation device 3 is arranged outside the small roller body 2;

[0022] The adjusting and lubricating installation device 3 includes a cylindrical roller bearing 301, a hollow shaft 302, a first threaded ring 303, a protective block 304, a wheel body 305, a rotating shaft 306, an arc block 307 and a bolt 308. The cylindrical roller bearing 301 is arranged inside the small roller body 2, the hollow shaft 302 is arranged outside the cylindrical roller bearing 301, the first threaded ring 303 is arranged outside the hollow shaft 302, the protective block 304 is arranged outside the hollow shaft 302, the wheel body 305 is arranged outside the Mecanum wheel body 1, the rotating shaft 306 is rotatably connected inside the wheel body 305, the arc block 307 is fixedly installed outside the rotating shaft 306, and the bolt 308 is arranged outside the arc block 307.

[0023] Specifically, Figure 2 As shown, the cylindrical roller bearing 301 is an important mechanical part, and its rolling element is a cylindrical roller, which belongs to a radial rolling bearing. The cylindrical roller bearing 301 has a large radial load-bearing capacity and can withstand heavy loads and impact loads, which enables the Mecanum wheel to remain stable in a complex working environment and withstand various forces. While the Mecanum wheel withstands radial loads, it also has a certain axial load-bearing capacity, thereby improving the stability of the overall structure.

[0024] Specifically, Figure 2 As shown, the hollow shaft 302 and the cylindrical roller bearing 301 are connected by interference fit. Interference fit refers to the radial pressure generated between the two mating parts after assembly. In the assembly of the cylindrical roller bearing 301 and the hollow shaft 302, if the fit between the bearing ring and the shaft or housing is interference fit, radial pressure will be generated after assembly, thereby tightly combining together. The interference fit improves the firmness and reliability of the connection and reduces failures caused by looseness or vibration.

[0025] Specifically, Figure 2As shown, the screw block on the outer surface of the first threaded ring 303 is adjusted and fixed in position by a rubber ring. Because the rubber material of the rubber ring has a certain degree of stretchability, it can move on the outer surface of the hollow shaft 302 after stretching. When the position of the screw block is fixed, it only needs to move the rubber ring to the screw block, and the rubber ring will return to its original position, and then cooperate with the first threaded ring 303 to generate friction, thereby limiting and fixing the screw block.

[0026] When implementing, follow these steps:

[0027] 1) First, by rotating the screw block outside the first threaded ring 303, the installation length of the hollow shaft 302 can be adjusted, and fixed by the rubber ring;

[0028] 2) Then the cylindrical roller bearing 301 is used to increase the rolling stability of the small roller body 2;

[0029] 3) Connect the oil delivery pipe and the hollow shaft 302 through the second threaded ring, remove the protective block 304, and pour the lubricating oil into the oil delivery pipe for lubrication and maintenance;

[0030] 4) Finally, the bolt 308 is removed to separate the arc block 307 through the rotating shaft 306, so that the hollow shaft 302 can be removed for maintenance.

[0031] In summary, the installation structure of the small roller of the Mecanum wheel can adjust the installation length of the hollow shaft 302 by rotating the screw block outside the first threaded circle 303. After the adjustment is completed, it is limited and fixed by a rubber ring. The stability of the small roller body 2 during rolling is increased by the cylindrical roller bearing 301. When lubrication is required, the oil pipeline is connected to the hollow shaft 302 through the second threaded circle, and the protective block 304 is removed to pour the lubricating oil into the oil pipeline, so as to lubricate and maintain the device. Finally, the bolt 308 is removed, and then the arc block 307 is driven to rotate by the rotation of the rotating shaft 306, so as to remove the hollow shaft 302 and perform maintenance operations on it. After completion, it is installed in the same way, and the hollow shaft 302 is protected against slip by the protective sheet to ensure the stability of the device, thereby achieving the purpose of easy adjustment and installation and lubrication effect.
