Abstract: Non-backlash gear drive mechanism consists of a housing part, a first gear, a second gear, a spring component, and a self-aligning bearing. The housing part contains a central shaft, a bearing mounting hole, and a limiting hole. By utilizing the automatic aligning characteristic of the self-aligning bearing and the elastic compression force of the spring component, it can eliminate and compensate for deviations during processing and assembly that may cause excessive backlash or gears to become stuck during transmission. As a result, this non-backlash gear transmission mechanism is particularly suited for gear drive applications with a light load, low rotational speed, frequent direction reversal, and requiring backlash elimination.
