Linear system for a manufacturing plant and method of assembling such a linear system

A linear system for a manufacturing system, comprising:

• a linear guide,
• a drive device, a spindle nut, and
• a spindle;
• wherein the spindle extends along an axis, and
• wherein the spindle nut is arranged on the spindle and the spindle nut and the spindle engage with each other;
• wherein the drive device is connected to the spindle nut in a manner configured to drive the spindle nut to rotate about the axis,
• wherein the spindle nut is configured to move the spindle along the axis upon rotation about the axis,
• wherein the spindle has a first spindle groove extending along the axis on a first outer circumferential side,
• wherein the linear guide comprises a guide housing arranged to prevent rotation of the guide housing about the axis, and a first ledge element,
• wherein the guide housing has a radially outwardly extending first receptacle,
• wherein the first ledge element comprises a radially outwardly disposed carrier and a ledge arranged radially inwardly of the carrier and connected to the carrier and extending along the axis, and
• wherein the first ledge element engages with the carrier in the first receptacle of the guide housing and with the ledge in the first spindle groove and is configured to guide the spindle in a direction along the axis,
• wherein the linear guide has a guide sleeve with a guide surface arranged radially on the inside,
• wherein the guide sleeve is coupled to the system housing and engages around the spindle, and
• wherein the guide surface abuts on the first outer circumferential side of the spindle and is configured to support a radial force from the spindle acting in the radial direction.

A linear system for a manufacturing system, comprising:

• a spindle nut, a spindle, and
• a system housing;
• wherein the spindle extends along an axis,
• wherein the spindle has a first spindle groove extending along the axis on a first outer circumferential side,
• wherein the linear guide comprises a guide housing arranged to prevent rotation of the guide housing about the axis, and a first ledge element,
• wherein the guide housing has a radially outwardly extending first receptacle,
• wherein the first ledge element comprises a radially outwardly disposed carrier and a ledge arranged radially inwardly of the carrier and connected to the carrier and extending along the axis,
• wherein the first ledge element engages with the carrier in the first receptacle of the guide housing and with the ledge in the first spindle groove and is configured to guide the spindle in a direction along the axis,
• wherein a second outer circumferential side of the carrier and a first inner circumferential side of the first receptacle are configured correspondingly to each other at least in sections,
• wherein the guide housing is fastened in the system housing of the linear system by a fastener,
• wherein the fastener is configured to introduce a clamping force into the guide housing to press the first inner circumferential side of the first receptacle at least sectionally against the second outer circumferential side and to fasten the carrier in the first receptacle thereby,
• and wherein, a second outer circumferential side of the carrier and a first inner circumferential side of the first receptacle are configured correspondingly to each other at least in sections.

• wherein the linear guide comprises a first spring element,
• wherein the first ledge element comprises a sliding surface on a side facing the spindle,
• wherein the carrier engages through the first receptacle in radial direction and protrudes from the first receptacle on a side facing away from the spindle,
• wherein the first spring element is arranged between an outer surface of the guide housing and a carrier outer surface of the carrier, and
• wherein the first spring element is configured to position the first ledge element in the first spindle groove in such a way that the sliding surface is arranged in the first spindle groove at a predefined third distance from a spindle groove base of the first spindle groove.
