Description

Technical Field

[0001] The utility model relates to the technical field of transmission gears, in particular to a high-strength and high-toughness transmission gear for an industrial servo system. Background Art

[0002] The servo system, also known as the follow-up system, is a feedback control system used to accurately follow or reproduce a process. The servo system is an automatic control system that enables the output controlled quantities such as the position, orientation, and state of an object to follow any changes in the input target (or given value). Its main task is to amplify, transform, and regulate the power according to the requirements of the control command, so that the torque, speed, and position control of the drive device output are very flexible and convenient. In many cases, the servo system specifically refers to a feedback control system in which the controlled quantity (the output of the system) is mechanical displacement or displacement velocity or acceleration. Its function is to make the output mechanical displacement (or angle of rotation) accurately track the input displacement (or angle of rotation). There is no fundamental difference between its structural composition and other forms of feedback control systems.

[0003] For example, the low-error transmission gear disclosed in publication number CN218468196U has the following beneficial effects: through the active connection between the incompletely overlapping transmission gear body and the differential gear body, during the meshing process of the driving gear body, the gap between the subsequent driving gear body and the transmission gear body is filled by the incompletely overlapping length, thereby reducing the error between the driving gear and the transmission gear body during operation.

[0004] Regarding the above solution: The reference document reduces the error between the driving gear and the transmission gear body during operation. However, during the continuous rotation of the transmission gear, due to various factors such as improper installation, excessive load or poor lubrication, the gear may be slightly offset. This offset will gradually accumulate under long-term operation, and eventually lead to uneven distribution of contact pressure between the teeth, causing local overload of the teeth. In the long run, the teeth may be worn, deformed, or even broken, seriously affecting the precise transmission and normal operation of the gears. Once this happens, the damaged gear must be replaced. The replacement of the gear not only involves a complicated disassembly and installation process, but also needs to consider the matching of the new gear with the original transmission system. Therefore, the replacement cost is often high. Utility Model Content

[0024] Specifically, a handle 8 is fixedly connected to one side of the adjustment block 76 , and a surface of the handle 8 is provided with anti-slip patterns.

[0025] In this embodiment, the handle 8 and the anti-slip pattern are used in combination to increase the friction between the palm of the user and the handle 8 , thereby facilitating the user to move the adjustment block 76 .

[0026] Specifically, two slide grooves 9 are provided on both sides of the inner cavity of the sleeve 6 , and a slider 10 is slidably connected to the inner cavity of the slide groove 9 , and one side of the slider 10 is fixedly connected to the annular block 73 .

[0029] In this embodiment, the receiving hole 11 is provided to receive the positioning column 77 , thereby increasing the contact between the adjusting block 76 and the round block 4 .

[0030] Specifically, the gear ring 1 includes two cast steels 101 disposed on the outermost sides, and forged steels 102 are fixedly connected to opposite sides of the two cast steels 101. The gear ring 1 and the round block 4 are made of the same material.
