What are the differences in structural characteristics of parallel shafts, vertical shafts, vertical and horizontal boxes of reducer

Parallel shaft box: The gear shafts in the box are arranged in parallel, and the axes of the input shaft and the output shaft are parallel to each other. This box structure is relatively simple and easy to process and assemble. Common ones include single-stage parallel-axis gearbox and multi-stage parallel-axis gearbox.

Direct axis box: The gear shafts in the box are arranged vertically, and the axis of the input shaft and the output shaft are perpendicular to each other. The vertical axis box usually uses transmission methods such as bevel gears or worm gears to achieve the transmission requirements of right-angle steering. Its structure is relatively complex and requires higher processing accuracy and assembly requirements.

Vertical box: The installation method of the box is vertical, that is, the axis of the box is perpendicular to the ground. Vertical boxes are usually used in situations where vertical installation is required, such as cranes, elevators, etc. Its advantage is that it covers a small area and can effectively utilize space, but the stability and support structure of the box need to be considered.
