<p>The present invention relates to a gear box that distributes or transmits power and, more particularly, to a three-direction backlashing gear box in which a direction of the power incoming through an input shaft is changed so that output shafts on both sides rotate with one of the two backlashing. Also, the present invention is to distribute the power for backlashing of a turning force of the input shaft in a first output shaft and a second output shaft by using a bevel gear and reduce noise generation by allowing the first output shaft and the second output shaft disposed in the gear box to rotate without shaking. According to the present invention, the turning force incoming from the input shaft is divided to be opposite in direction in the output shafts on both of the sides and the output shafts on both of the sides are supported in a state of being coupled to be capable of backlashing while rotating. According to the present invention, the output shafts on both of the sides that backlash are coupled with each other and thus no shaking occurs. Accordingly, noise generation can be significantly reduced and the size of the gear box can be minimized. The present invention is simple in structure, can be easily manufactured, and can be used for various purposes in such fields as construction, textile, agriculture, mining, and machinery owing to the small size thereof.</p> |
