Spur |
Excellent |
Parallel shaft. Highspeed,load,and efficiency. Recommended for all gearmeshes except where right-angle drive cannot be avoided. |
Bevel |
Fair to Good |
Intersecting shaft. High speed and load. Recommended for right-angle drive, particularly low ratios. Should be located at one of the less critical meshes of DriveTrain. |
Helical |
Good |
Parallel shaft. High speed and load. Efficiency slightly less than spur. Equivalent quality to spurs except for complication of thir angle. Recommended for all high-speed and high-load meshes. Axial thrust component must be accommodated. |
Worm |
Fair to good |
Right-Angle shaft. High speed and load. Low efficiency. Recommendedfor combination high speed and right-angle drive. High sliding requires lubrication. |
