Section: Generic Linear Bearings

Module: linear_bearing_housing()

Synopsis: Creates a generic linear bearing mount clamp. ^[Geom]

Topics: Parts, Bearings

Usage:

linear_bearing_housing(d, l, tab, gap, wall, tabwall, screwsize) [ATTACHMENTS];

Description:

Creates a model of a clamp to hold a generic linear bearing cartridge.

Arguments:

By Position	What it does
`d`	Diameter of linear bearing. (Default: 15)
`l`	Length of linear bearing. (Default: 24)
`tab`	Clamp tab height. (Default: 8)
`tabwall`	Clamp Tab thickness. (Default: 5)
`wall`	Wall thickness of clamp housing. (Default: 3)
`gap`	Gap in clamp. (Default: 5)
`screwsize`	Size of screw to use to tighten clamp. (Default: 3)

By Name	What it does
`anchor`	Translate so anchor point is at origin (0,0,0). See anchor. Default: `CENTER`
`spin`	Rotate this many degrees around the Z axis after anchor. See spin. Default: `0`
`orient`	Vector to rotate top towards, after spin. See orient. Default: `UP`

Example 1:

$linear\_bearing\_housing() Example 1$

include <BOSL2/std.scad>
include <BOSL2/linear_bearings.scad>
linear_bearing_housing(d=19, l=29, wall=2, tab=8, screwsize=2.5);

Module: linear_bearing()

Synopsis: Creates a generic linear bearing cartridge. ^[Geom]

Topics: Parts, Bearings

Usage:

linear_bearing(l, od, id, length) [ATTACHMENTS];

Description:

Creates a rough model of a generic linear ball bearing cartridge.

Arguments:

By Position	What it does
`l` / `length`	The length of the linear bearing cartridge.
`od`	The outer diameter of the linear bearing cartridge.
`id`	The inner diameter of the linear bearing cartridge.

By Name	What it does
`anchor`	Translate so anchor point is at origin (0,0,0). See anchor. Default: `CENTER`
`spin`	Rotate this many degrees around the Z axis after anchor. See spin. Default: `0`
`orient`	Vector to rotate top towards, after spin. See orient. Default: `UP`

Example 1:

$linear\_bearing() Example 1$

include <BOSL2/std.scad>
include <BOSL2/linear_bearings.scad>
linear_bearing(l=24, od=15, id=8);

Section: lmXuu Linear Bearings

Module: lmXuu_housing()

Synopsis: Creates a standardized LM*UU linear bearing mount clamp. ^[Geom]

Topics: Parts, Bearings

Usage:

lmXuu_housing(size, tab, gap, wall, tabwall, screwsize) [ATTACHMENTS];

Description:

Creates a model of a clamp to hold a standard sized lmXuu linear bearing cartridge.

Arguments:

By Position	What it does
`size`	Standard lmXuu inner size.
`tab`	Clamp tab height. Default: 7
`tabwall`	Clamp Tab thickness. Default: 5
`wall`	Wall thickness of clamp housing. Default: 3
`gap`	Gap in clamp. Default: 5
`screwsize`	Size of screw to use to tighten clamp. Default: 3

By Name	What it does
`anchor`	Translate so anchor point is at origin (0,0,0). See anchor. Default: `CENTER`
`spin`	Rotate this many degrees around the Z axis after anchor. See spin. Default: `0`
`orient`	Vector to rotate top towards, after spin. See orient. Default: `UP`

Example 1:

$lmXuu\_housing() Example 1$

include <BOSL2/std.scad>
include <BOSL2/linear_bearings.scad>
lmXuu_housing(size=10, wall=2, tab=6, screwsize=2.5);

Module: lmXuu_bearing()

Synopsis: Creates a standardized LM*UU linear bearing cartridge. ^[Geom]

Topics: Parts, Bearings

Usage:

lmXuu_bearing(size) [ATTACHMENTS];

Description:

Creates a model of an lmXuu linear ball bearing cartridge.

Arguments:

By Position	What it does
`size`	Standard lmXuu inner size.

By Name	What it does
`anchor`	Translate so anchor point is at origin (0,0,0). See anchor. Default: `CENTER`
`spin`	Rotate this many degrees around the Z axis after anchor. See spin. Default: `0`
`orient`	Vector to rotate top towards, after spin. See orient. Default: `UP`

Example 1:

$lmXuu\_bearing() Example 1$

include <BOSL2/std.scad>
include <BOSL2/linear_bearings.scad>
lmXuu_bearing(size=10);

Section: lmXuu Linear Bearing Info

Function: lmXuu_info()

Synopsis: Returns the sizes of a standard LM*UU linear bearing cartridge.

Topics: Parts, Bearings

Usage:

diam_len = lmXuu_info(size);

Description:

Get dimensional info for a standard metric lmXuu linear bearing cartridge. Returns [DIAM, LENGTH] for the cylindrical cartridge.

Arguments:

By Position	What it does
`size`	Inner diameter of lmXuu bearing, in mm.
