[0001] The utility model relates to the technical field of adjusting devices, in particular to a worm gear center distance adjusting device. Background Art
[0002] A worm gear is a common transmission device, which consists of a worm wheel and a worm. They are usually used to transfer power from a high-speed rotating worm wheel to a low-speed rotating output shaft to achieve a change in speed and direction. Worm gears are common in many military industries. Armored vehicles and signal vehicles in the military industry can all be applied to worm transmission. The center distance between the worm wheel and the worm refers to the center distance between the worm wheel and the worm. The center distance needs to be adjusted and fixed by an adjustment device to ensure the correct fit and effective transmission between the worm wheel and the worm. In the existing adjustment device, during the adjustment process, a tool is usually used to tighten or loosen the adjustment nut to adjust the center distance between the worm wheel and the worm. Since the adjustment nut is manually driven to adjust the center distance between the worm wheel and the worm, when frequent adjustment is required, the adjustment speed is slow, reducing the overall adjustment rate. At the same time, the accuracy of manual adjustment is easily affected by human factors, resulting in inadequate adjustment or over-adjustment, affecting the accuracy of the center distance, and affecting the transmission effect and stability of the worm gear; therefore, a worm gear center distance adjustment device is proposed to solve the above-mentioned problems.
