Because it is a mechanical transmission, it is convenient to repair when problems occur. Even if the torque is overloaded, the power transmission lever on the circular wheel will slip out due to the excessive transmission force, so that the circular transmission ring driven by the motor will rotate idly, so that the motor will not be stuck or overloaded. In this way, even if it is blocked, it only needs to install the transmission rod back, thereby effectively improving the practicality of the transmission structure.

Description

Technical Field

[0001] The utility model belongs to the technical field of rotating equipment, and in particular relates to a transmission structure for preventing transmission from stalling. Background Art

[0002] The transmission structure that prevents transmission jams usually needs to have the following features: Overload protection mechanism: When designing, the possible overload situation is taken into consideration. By setting up clutches, brakes or torque limiters, when the load exceeds the set value, these protection mechanisms can automatically disconnect or reduce the transmission to avoid jams. Elastic connection: Connectors made of materials such as rubber and elastic metal can absorb vibration and impact to a certain extent, reducing the risk of jams caused by mechanical vibration. Accurate transmission ratio: Ensure that the various components of the transmission system can be accurately matched to avoid mechanical jams caused by improper transmission ratios. Lubrication and cooling system: For high-speed or high-load transmission systems, good lubrication and cooling can reduce wear and heat accumulation and reduce the risk of jams. High-quality parts: Use high-precision and high-quality standard parts to reduce jams caused by component defects. Intelligent monitoring: By installing sensors and actuators, the status of the transmission system is monitored in real time. Once an abnormality is detected, the protection program is immediately activated to cut off the power source to avoid further damage. Easy maintenance and repair: The design takes into account the convenience of maintenance and repair, so that once a jam occurs, it can be quickly located and solved. Reasonable layout design: avoid mechanical interference and movement restriction caused by unreasonable spatial layout, thereby reducing the possibility of stalling.

[0003] The previous transmission parts were either steering gear, control transmission, or motor plus tire and other wheel-shaped transmission, but these transmission methods have the following disadvantages:

[0004] 1: The servo transmission is prone to burn out the servo control board when the power consumption is high or the motor is stuck.

[0005] 2: The torque of the servo transmission is too small and cannot provide the torque required by the multi-legged robot.

[0006] 3: Tires cannot realize the transmission of multi-legged robots. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the existing defects and provide a transmission structure for preventing transmission jam, so as to solve the problems raised in the above background technology: 1. The servo transmission is easy to burn the servo control board when the motor is stuck at high power consumption; 2. The torque of the servo transmission is too small to provide the torque required by the multi-legged robot; 3. The tire cannot realize the transmission of the multi-legged robot.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transmission structure for preventing transmission jam, comprising a transmission device body, a connecting rod is fixedly connected to one end of the transmission device body, a positioning block is slidably connected to the outside of the connecting rod, a positioning rod is symmetrically fixedly connected to the outside of the positioning block, a mounting bracket is arranged on the outside of the positioning block, a spring is symmetrically fixedly connected to the upper and lower ends of the positioning block, a transmission rod is arranged on the inner side of the mounting bracket close to the transmission device body, a clamping block is fixedly connected to one end of the transmission rod, a partition bin is arranged on the side of the transmission device body away from the mounting bracket, a rotating shaft is symmetrically rotatably connected to the inside of the partition bin, a gear is fixedly connected to the outside of the rotating shaft, a circular transmission ring is fixedly connected to one end of the rotating shaft close to the transmission rod, and the circular transmission ring has a circular interior and a through groove is provided.

[0010] Preferably, the spring is located between the transmission device body and the positioning block.

[0011] Preferably, the transmission rod is fixedly connected to the mounting bracket via a clamping block.

[0016] 1. The utility model provides a transmission structure to prevent transmission jam, and the torque provided can be much greater than the torque of an ordinary robot servo. Because it is a mechanical transmission, it is easy to repair if there is a problem. Even if the torque is overloaded, the power transmission rod on the round wheel will slip out due to the excessive transmission force, which will cause the circular transmission ring driven by the motor to idle, so that the motor will not be stuck or overloaded. In this way, even if it is blocked, it only needs to reinstall the transmission rod, thereby effectively improving the practicality of the transmission structure;

[0017] 2. The utility model sets a connecting rod and a spring. During the operation of the transmission structure, the connecting rod and the connecting rod are arranged at the front end of the transmission device body. When the transmission rod slips out due to excessive transmission force, the mounting bracket will slide up and down under the elastic action of the spring, and the overload force will be avoided in time to prevent damage.

The torque provided can be much larger than the torque of an ordinary robot servo. Because it is a mechanical transmission, it is easy to repair if there is a problem. Even if the torque is overloaded, the power transmission lever on the circular wheel will slip out due to the excessive transmission force, which will cause the circular transmission ring driven by the motor to idle, so that the motor will not be stuck or overloaded. In this way, even if it is blocked, you only need to install the transmission rod back, thereby effectively improving the practicability of the transmission structure.

[0033] The working principle and use process of the utility model: when in use, the torque of the servo is small, and the mechanical transmission we use relies on the overall coordination of the transmission structure parts, and cooperates with the lever torque to amplify it. The transmission structure can cause the transmission rod to be "dislocated" by high torque when the motor and the transmission parts are stuck. Thereby, the circular transmission ring will idle without burning the motor, and the torque provided can be much larger than the torque of the ordinary robot servo. Because it is a mechanical transmission, it is easy to repair when problems occur. Even if the torque is overloaded, the power transmission lever on the round wheel will slip out due to the excessive transmission force, which will cause the circular transmission ring driven by the motor to idle, so that the motor will not be stuck or overloaded; in this way, even if it is blocked, you only need to install the transmission rod back, thereby effectively improving the practicality of the transmission structure.
