Mates Types in SolidWorks

3 categories of mates types in SolidWorks:

Standard

AdvancedMechanical

Coincident mate

.

Locates the selected faces, edges, points or planes so they use the same

infinite line/plane.

A Coincident mate positions two vertices for contact.

Example:

Coincident mate

: positions two vertices for contact.

Note: The Icon feedback symbol in SolidWorks for a Face, Edge, vertex, etc.

Parallel mate

:

Locates selected

items to lie in parallel planes

Allows only

translation and rotation that

keeps the selected items parallel

.

Perpendicular mate

Locates selected items at a

90

deg angle to each other.

allows both translation & rotation of one part with respect to another.

Tangent

mate

Places selected items tangent to each other.

At least one selected item must be either a

conical, cylindrical, spherical face.

Concentric

mate

Locates selected items so they can share the

same center point.

Note: sometimes we want to prevent rotation in a concentric mate (e.g. putting a cam on a shaft).

Just check “Lock Rotation” option in the mate property manager.

Distance

mate

Locates selected items with

specified distance between them.

Use drop-down arrow box or enter dist value directly.

Advanced

mates

Distance mate

(Limit mate)

. allow components to move within a range of values for distance and angle. Distance. Locates the selected items with a specified distance between them. Angle. Locates the selected items at the specified angle to each other.

Angle

mate

Locates selected items at specified angle to each other.

Use drop-down arrow box or enter angle value directly.

Mechanical

mates

Cam mate

. Forces plane, cylinder, or point to be tangent or coincident to a series of tangent extruded faces. Create Cam profile from lines, arcs, and splines that

are tangent and form a closed loop.

SW: a

type of tangent or coincident mate.

mate cylinder

, plane, or

point

to

series

of tangent extruded

faces (like on a cam).

Figure: 3 followers stay

in contact with

cam

as it rotates.

Cam mate

eg

Cam mate:

Cam profile MUST be a series of TANGENT extruded faces that form a closed loop.Cam Profile Can Be:LinesArcs

SplinesCam follower: portion to be mated must be Cylindrical facePlanar faceVertex

Hinge

mate

Limits movement between 2 components to 1 rotational

dof.

Equiv to Concentric + Coincident. (can also limit angular movement between components).

Gear mate

Make 2 components rotate relative to each other, around selected axes.

establish gear type relations between components without making components physically mesh.

Align components before adding Mechanical gear mate.Can simulate BELT separate gears spatially and select Reverse

to change direction of rotation of output gear.

Gear & pulley examples

Adapted from Lego site

Compound belt drivers

Pulleys at an angle – change rotation direction

- driver gear at 90

deg

to follower.

direction of rotation changes 90

deg

when driver is turned.

This

eg

also shows a gearing down arrangement - driver pulley < follower.
