Abstract
The utility model discloses a heavy-load roller linear guide rail pair. The heavy-load roller linear guide rail pair adopts the structure that an upper guide rail raceway and a lower guide rail raceway are respectively arranged on two sides of a guide rail; an upper slide block raceway and a lower slide block raceway are respectively arranged on two side walls of the groove of a slide block; roller return passages corresponding to the guide rail raceways are arranged in the slide block; a plurality of rollers are arranged between the guide rail raceways and the slide block raceways; the guide rail raceways and the slide block raceways are plane; the widths of the guide rail raceways and the slide block raceways are both greater than the length of the rollers; each roller comprises a straight line section in the middle and transition curve sections at the two ends; the rollers do reciprocating motion between the guide rail and the slide block through a roller return mechanism. As the widths of the guide rail raceways and the slide block raceways are both greater than the length of the rollers, and each roller comprises the straight line section in the middle and the transition curve sections at the two ends, the contact states of the rollers and the raceways are improved, the stress concentration phenomenon, at the two ends of each roller, caused by the contact between the roller and the raceways is eliminated. Therefore, the bearing capability and rigidity of the heavy-load roller linear guide rail pair are improved.
Description
Technical field
The utility model relates to a kind of roller line slideway auxiliary, especially relates to a kind of heavily loaded roller line slideway auxiliary.
Background technique
Now, along with the future development of all kinds of electromechanical integration equipments to highi degree of accuracy, fast-response and energy-conserving and environment-protective, linear rolling guide has obtained increasing application, roller line slideway auxiliary particularly, because its rolling element is roller, bearing capacity, higher than take the ball linear guide pairs that ball is rolling element, is applied in the middle of all kinds of heavy electromechanical integration equipments, especially in large-size numerical control machine.But because roller and raceway are that line contacts, have the concentrated edge effect of stress, so the contact condition of roller and raceway affects the bulk life time of guiding pairs.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of load-carrying rolling linear guide pairs of the concentration phenomenon that can eliminate stress.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of heavily loaded roller line slideway auxiliary, comprise the reeded slide block of guide rail and tool, described slide block set is on described guide rail, described guide rail both sides are respectively arranged with upper and lower two guide rail raceways, on the groove two side of slide block, be respectively arranged with upper and lower two slide block raceways, in described slide block, be provided with the roller back passage corresponding with described guide rail raceway, between described guide rail raceway and slide block raceway, be provided with a plurality of rollers, described guide rail raceway and slide block raceway are plane, the width of guide rail raceway and slide block raceway is all greater than the length of roller, described roller comprises the straightway in the middle of being positioned at and is positioned at the transition curve section at two ends, described roller moves in circles between guide rail and slide block by roller reversing mechanism.
Between described upper rail raceway and lower rail raceway, become 90 degree angles.
compared with prior art, advantage of the present utility model is because the width of guide rail raceway and slide block raceway is greater than roller length, described roller comprises the straightway in the middle of being positioned at and is positioned at the transition curve section at two ends, improved the contact condition of roller and raceway, eliminate roller and contacted the roller two ends stress concentration phenomenon producing with raceway, thereby improved bearing capacity and the rigidity of roller line slideway auxiliary, extended the whole service life of roller line slideway auxiliary.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
A kind of heavily loaded roller line slideway auxiliary, comprise the reeded slide block 2 of guide rail 1 and tool, slide block 2 is enclosed within on guide rail 1, guide rail 1 both sides are respectively arranged with upper and lower two guide rail raceways 3, 4, on the groove two side of slide block 2, be respectively arranged with upper and lower two slide block raceways 5, 6, in slide block 2, be provided with and guide rail raceway 3, 4 corresponding roller back passages 7, 8, guide rail raceway 3, 4 and slide block raceway 5, between 6, be provided with a plurality of rollers 9, guide rail raceway 3, 4 and slide block raceway 5, 6 are plane, guide rail raceway 3, 4 and slide block raceway 5, 6 width is all greater than the length of roller 9, roller 9 comprises the straightway 91 in the middle of being positioned at and is positioned at the transition curve section 92 at two ends, roller 9 moves in circles between guide rail 1 and slide block 2 by roller reversing mechanism (figure does not show).Between upper rail raceway 3 and lower rail raceway 4, become 90 degree angles.
