Abstract
The utility model relates to a rolling linear guide rail pair, particularly a rolling linear guide rail pair used for heavy loads. The utility model comprises a guide rail and a slide block, wherein the inner side of the slide block and the outer side of the guide rail are respectively provided with N rollaway nests which are mutually adaptive, a rolling body is arranged between the rollaway nest of the inner side of the slide block and the rollaway nest of the outer side of the guide rail, both ends of the slide block are provided with return trace devices and the rolling body is a roller. The utility model has the advantages that the roller is adopted to replace a steel ball to be used as the rolling body, the utility model can not only keep the ascendancy and the characteristics of the rolling linear guide rail pair in a steel ball type, but also change the point contact of the steel ball to the line contact of the roller. The capacity of bearing loads can be improved, requirements of bearing heavy machinery can be satisfied, thereby, the application area of the rolling linear guide rail pair can be widened.
Description
Technical field
The utility model relates to a kind of linear rolling guide, particularly a kind of linear rolling guide that is applied under the heavy load.
Background technique
Numerical control device machine-tool industry at home, printing machinery, engraving machinery etc. use the such straight line motion products of linear guide pairies in a large number in many automation transmissions at present.As shown in Figure 1, domestic present linear guide pairs is made up of guide rail 3, slide block 1, steel ball 6, backhaul device etc.When guide rail and slide block were done relative movement, the steel ball just raceway on the guide rail rolled, and enters raceway again after slide block end steel ball enters the backhaul hole by the backhaul device again, and steel ball carries out rolling motion like this again and again.This linear rolling guide makes the sliding friction between slide block and the guide rail become rolling friction because of put into suitable steel ball between slide block and guide rail, reduces the kinetic friction resistance of the two greatly, thereby the difference that obtains sound frictional force is very little, and servo-actuated is fabulous.But because of adopting steel ball as rolling element, it is that steel ball point contacts with contacting of guide rail and slide block, and bearing capacity is poor, can only be applicable to that some are light, in the machinery of middle load, and can not be applied in the heavier control feel simulator.
Summary of the invention
In order to address the above problem, the purpose of this utility model provides a kind of rolling linear guide that can work under heavy load.
To achieve these goals, the technical solution adopted in the utility model provides a kind of linear rolling guide, comprise guide rail, slide block, slide block is inboard respectively to be provided with the suitable raceway of N bar with the guide rail outside, be provided with rolling element between the raceway in the raceway of slide block inboard and the guide rail outside, be provided with the backhaul device at the two ends of slide block, described rolling element is a roller.
Described roller is a cylindrical roller; Described roller is a needle roller; Be provided with retainer between the described roller; Described raceway is the straight line raceway, the width of raceway and roller big or small suitable; Described straight line raceway becomes 45 degree with horizontal plane; Described N=2-8; Described N=4.
The beneficial effects of the utility model are to adopt roller to replace steel ball as rolling element, the utility model not only keeps the advantage and the characteristics of steel ball type linear rolling guide, and with the line contact of the point of steel ball contact becoming roller, the ability of bearing load improves greatly, satisfy the requirement of carrying heavy machinery, thus the application of the linear rolling guide of widening.

Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in more detail.
As shown in Figures 2 and 3, a kind of linear rolling guide, comprise guide rail 3, slide block 1, there are 4 straight line raceways 5 slide block 1 inboard, be that inboard, slide block 1 both sides respectively has 2 straight line raceways, also there are 4 straight line raceways 5 in the outside of suitable with it guide rail 3, be provided with cylindrical roller 2 between the raceway in the raceway of slide block 1 inboard and guide rail 3 outsides, the width of straight line raceway 5 and cylindrical roller 2 big or small suitable, straight line raceway 5 becomes 45 degree with horizontal plane, be that the raceway in guide rail 3 outsides and the raceway of slide block 1 inboard are parallel to each other, and become 45 degree with horizontal plane, two ends at slide block 1 also are provided with backhaul device 4, can will slide into the cylindrical roller 2 of slide block 1 end enter straight line raceway 5 again after entering the backhaul hole by backhaul device 4, cylindrical roller 2 just can roll again and again like this.When guide rail 3 and slide block 1 were done relative movement, cylindrical roller 2 is straight line raceway 5 rollings on the guide rail 3 just, make the sliding friction between slide block 1 and the guide rail 3 become rolling friction, reduce the kinetic friction resistance of the two greatly.Cylindrical roller 2 rolls on the straight line raceway 5 between guide rail 3 and the slide block 1, both can bear load vertically downward, can bear the load of both sides again, can bear certain tilting moment again simultaneously, and stability and load-carrying ability all are greatly improved.According to the load needs, the straight line raceway also can be designed to 2 roads, 6 roads, 8 roads etc., different series such as that the columns of corresponding roller also can be designed to is single-row, biserial, four row.Roller also can be designed to needle roller, also can be provided with retainer between the roller.
