General knowledge of axis gear


Axis gear refers to a mechanical part which bears rotating parts and rotates along with it for delivering motion, bending moment and twisting moment. And the common form is round metal bar shape, of which, each section has different sizes in diameter. As a part of making rotational motion, it’s installed upon corresponding shaft.


Per its different shapes of axes, they can be classified into crank shafts and straight shafts. And according to their loading conditions, they can be divided into: 1. Rotation Shaft, 2. Spindle Shaft, 3. Transmission Shaft.


In the designing process, applications of axis gear are generally nothing less than the following situations:

1. Axis gear is generally small gear (namely, gears with fewer teeth). 2. Axis gear rotate in high-speed level (namely, in low-torque level). 3. Axis gear are less likely to be acted as sliding gears within gearshift mechanisms. And axis gear are commonly used as gears in fixed operations. One of the reasons is that the kind gears are generally in high-speed level, they’re not fit for being used in sliding and variable speed motions. 4. Though one axis gear is generally deem as a combination of one axis and one gear, we still try to shorten the length of axis in design. Because for one thing is that one so long axis hampers the machining upon gear hobbing machine. For one thing, one so long bearing forces to bold the gear for strengthening its own mechanical strength (such as rigidity, flexivity, bending resistance and etc.).
