1. Spur Gear Planetary Reducer vs Helical Gear Planetary Reducer
Spur Gear Type Appearance
The gear teeth are vertically parallel and straight without any helix angle.Viewed from the side, the gear teeth run straight up and down.It usually adopts a standard housing with a simple end face, mostly for economical models.
Helical Gear Type Appearance
The gear teeth are arranged in a spiral inclined angle.The tooth lines show an oblique shape from the side view.The housing is thickened and reinforced with refined workmanship, presenting a more delicate texture and compact structure.
2. Flange Output Reducer vs Shaft Output Reducer
Shaft Output Type Appearance
A solid round shaft extends from the front end.It relies on a coupling to connect the load.Overall shape is slender with an exposed driving shaft at the front.
Flange Output Type Appearance
No protruding shaft at the front; equipped with a large round flange plate.Mounting bolt holes are distributed around the flange, with hollow or solid center.The body is wider and thicker with a larger mounting surface, showing high rigidity visually.
3. Standard Type vs High-Rigidity / Heavy-Duty Type Reducer
Standard Economical Type Appearance
Thin and ordinary housing with simple surface treatment, no reinforcing ribs or thickened structure.The flange is thin with standard bolt holes, and the overall structure is lightweight.
High-Rigidity / Heavy-Duty Type Appearance
Thickened and strengthened housing with outer reinforcing ribs, solid and heavy structure.Thicker flange plate and thicker mounting holes; most adopt reinforced black housing design.Overall structure is more robust and solid than standard models of the same specification.
4. Single-Stage Reducer vs Two-Stage Reducer
Single-Stage Appearance
Short body length with only one section of gear housing.Only one dividing line on the shell surface, small and compact in size.
Two-Stage Appearance
Obviously longer body with two assembled housing sections.Two segmented rings can be seen on the appearance, layered structure obvious.Much longer than single-stage models with the same flange size.
5. In-Line Coaxial Reducer vs Right-Angle 90° Reducer
In-Line Coaxial Type Appearance
Input shaft and output shaft are on the same straight line.Overall shape is straight cylindrical with a linear structure from start to end.
Right-Angle Type Appearance
Input and output form a 90° L-shaped turn.Overall L-shaped structure, horizontal at one end and vertical at the other.
