Carriage of a linear guide

A carriage of a rail guide, the carriage comprising:

• a plurality of rolling element channels, wherein the plurality of rolling element channels include a plurality of rolling elements that continuously rotate through the plurality of rolling element channels, and
• a plurality of lubricant channels, wherein the plurality of lubricant channels are connected to the plurality of rolling element channels to supply the plurality of rolling element channels with a lubricant, wherein the plurality of lubricant channels comprise:
• a first-order lubricant channel extending from an external lubricant connection point to a first distribution point;
• second-order lubricant channels connected to the first distribution point and extending to a second distribution point;
• and
• third-order lubricant channels connected to the second distribution point and extending to a transfer section, the transfer section connecting the third-order lubricant channels to one of the plurality of rolling element channels, the first-order lubricant channel, the second-order lubricant channels, and the third-order lubricant channels being connected successively in series in a flow direction of the lubricant, a sum of flow cross-sectional areas of the second-order lubricant channels being equal to a flow cross-sectional area of the first-order lubricant channel.

A method of operating a carriage of a rail guide, the method comprising:

• continuously rotating a plurality of rolling elements through a plurality of rolling element channels to move the carriage along a rail;
• and
• supplying the plurality of rolling element channels with a lubricant via a plurality of lubricant channels, wherein the plurality of lubricant channels comprise:
• a first-order lubricant channel extending from an external lubricant connection point to a first distribution point;
• second-order lubricant channels connected to the first distribution point and extending to a second distribution point;
• and
• third-order lubricant channels connected to the second distribution point and extending to a transfer section, the transfer section connecting the third-order lubricant channels to one of the plurality of rolling element channels, the first-order lubricant channel, the second-order lubricant channels, and the third-order lubricant channels being connected successively in series in a flow direction of the lubricant, a sum of flow cross-sectional areas of the second-order lubricant channels being equal to a flow cross-sectional area of the first-order lubricant channel.
