Abstract:
A three-rows-of-ball bearings sliding rail is disclosed. An inner sliding rail body ( 1 ) is supported in outer sliding rail bodies ( 2 - 1, 2 - 2 ) through three rows of support ball bearings ( 3 - 1, 3 - 2, 3 - 3 ) which are arranged in parallel in a lengthwise direction of the inner sliding rail body. The three rows of support ball bearings ( 3 - 1, 3 - 2, 3 - 3 ) are respectively limited within a length range of the outer sliding rail bodies ( 2 - 1, 2 - 2 ) via ball retainers ( 4 ). Each of the outer sliding rail bodies ( 2 - 1, 2 - 2 ) includes a bottom plate ( 21 ), a first side wall ( 221 ) and a second side wall ( 222 ) which are respectively located at two sides in a widthwise direction of the bottom plate ( 21 ), are integrally formed with the bottom plate ( 21 ) and extended in a lengthwise direction of the bottom plate ( 21 ). The first side wall ( 221 ) includes a first arm and a supporting part ( 2211 ) which is bent inwardly and extends horizontally from a bottom end of the first arm. The second side wall ( 222 ) includes a second arm and an arc-shaped part ( 2221 ) which is bent inwardly from a bottom end of the second arm and integrally formed with the second arm. The three rows of support ball bearings ( 3 - 1, 3 - 2, 3 - 3 ) are respectively located within an upper inner corner end and a lower inner corner end of the first side wall ( 221 ), and the arc-shaped part ( 2221 ) in a cross section of the outer sliding rail bodies ( 2 - 1, 2 - 2 ); and connection lines of centers of the three rows of support ball bearings ( 3 - 1, 3 - 2, 3 - 3 ) form an equilateral triangle in the cross section of the outer sliding rail bodies ( 2 - 1, 2 - 2 ). This sliding rail can solve the problem of insufficient bearing capacity in the existing three-rows-of-ball bearings sliding rail, and can meet installation space requirements for a hidden sliding rail.

Claim (Index 1):
A three-rows-of-ball bearings sliding rail, which comprises an inner sliding rail body and at least one outer sliding rail body, wherein the inner sliding rail body is respectively supported in the outer sliding rail body through three rows of support ball bearings which are arranged in parallel in a lengthwise direction of the inner sliding rail body; the three rows of support ball bearings are respectively limited within a length range of the outer sliding rail body via a ball retainer; the inner sliding rail body translates along the outer sliding rail body under a support of the three rows of support ball bearings; the outer sliding rail body comprises a bottom plate, a first side wall and a second side wall which are respectively located at two sides in a widthwise direction of the bottom plate, are integrally formed with the bottom plate and extended in a lengthwise direction of the bottom plate; the first side wall comprises a first arm and a supporting part which is bent inwardly and extends horizontally from a bottom end of the first arm; the second side wall comprises a second arm and an arc-shaped part which is bent inwardly from a bottom end of the second arm and integrally formed with the second arm; each group of the three rows of support ball bearings are respectively located within an upper inner corner end and a lower inner corner end of the first side wall, and the arc-shaped part in a cross section of the outer sliding rail body; and connection lines of centers of each group of the three rows of support balls form an equilateral triangle in the cross section of the outer sliding rail body; the inner sliding rail body has multiple arc-shaped faces which respectively match with ball profiles of the three rows of support ball bearings.
