Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of Mecanum wheels, in particular to a Mecanum wheel with a mortise and tenon structure. Background Technique
[0002] A Mecanum wheel is a mechanical device often used as equipment for measuring and counting mechanical movements. It is usually used in various mechanical and engineering applications, especially in situations where the number of rotations of a shaft or the linear velocity needs to be accurately measured. It is usually a wheel with rollers, and the number and size of the rollers are usually designed according to specific application requirements. The Mecanum wheel is usually connected to a measuring device, such as a rotary encoder or a counter. These devices can record or transmit the rotation or linear velocity data of the Mecanum wheel. The working principle of the Mecanum wheel is based on the interaction between its rollers and other mechanical components. When the Mecanum wheel comes into contact with the moving parts of a mechanical system, the rotation or movement of the rollers will be recorded by the measuring device. In this way, by analyzing the recorded data, the number of times, speed or other relevant parameters of the measured mechanical movement can be calculated.
[0003] The structure of the traditional Mecanum wheel uses two plates to fix small rollers at a 45° angle on the circumference. The plate is a cantilever mechanical structure. To ensure strength, the thickness of the plate is usually relatively thick. The plate and the roller are at a spatial angle, making the processing of the plate complex. Since the hub has a fixed diameter, Mecanum wheels of different diameters need to be replaced as a whole. And the traditional Mecanum wheel hub is manufactured by CNC, with a high manufacturing cost of the hub; the hub is a cantilever structure, with poor mechanical structure performance and is easily damaged by impact; after the integral hub is damaged, the wheel needs to be removed to replace the entire web, resulting in a high maintenance cost; there is also the drawback that the diameter is a fixed value and cannot be randomly combined with different diameters. Content of the Utility Model
[0004] The purpose of the utility model is to solve the problem of a large amount of resource consumption in the traditional manufacturing process, and to propose a Mecanum wheel with a mortise and tenon structure.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A Mecanum wheel with a mortise and tenon structure, including a web. A plurality of first bayonets are arranged on the outer surface of the web, and a plurality of second bayonets are arranged on the outer surface of the web. A roller bracket is arranged inside the first bayonet. A first connection port is opened on the lower surface of the roller bracket, and the first connection port engages with the first bayonet. A first clamping position is opened on the lower surface of the roller bracket, and the first clamping position engages with the second bayonet. A second clamping position is opened on the lower surface of the roller bracket, and the second clamping position is clamped with the second clamping position of the adjacent roller bracket. A second connection port is opened on the lower surface of the roller bracket, and the second connection port engages with the inside of the first bayonet.
[0006] Preferably, connection holes are formed on the outer surface of the roller bracket, and a roller body is rotatably connected inside the connection holes.
[0007] Preferably, the outer surface of the roller body is rotatably connected inside the roller bracket.
[0008] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:
[0009] First, in the present utility model, the structure is relatively material-saving. Under the same strength, the weight of the hub is lighter, the processing difficulty is small, and the mechanical effect is good. The hub is of a squirrel-cage structure, and the roller brackets are mutually engaged to form an X-shaped modular structure. The roller brackets can be replaced and combined into Mecanum wheels with different diameters. BRIEF DESCRIPTION OF THE DRAWINGS
