Abstract
The invention belongs to the technical field of linear guide rail pairs, and particularly relates to a radial heavy load type roller linear guide rail pair. The radial heavy load type roller linear guide rail pair comprises a guide rail and a sliding base. The upper portion of the sliding base is provided with a row of a roller guide groove and a row of an upper roller path, and two rows of lateral roller paths are symmetrically arranged on the two sides of the sliding base; rollers bearing radial pressure loads are arranged in the upper roller path, rollers bearing lateral pressure loads are arranged in the lateral roller paths through retainers, each roller is a circular cylinder with protruding shoulders at the two ends, and the rollers are in linear contact with the roller path face of the upper roller path and the roller path faces of the lateral roller paths. The rollers stably move in the roller paths and can bear acting force in all directions, abrasion of contact surfaces of the rollers and the roller paths is low, and thus the service life of the radial heavy load type roller linear guide rail pair is long. Compared with a traditional product, contact rigidity of the radial heavy load type roller linear guide rail pair is increased to about 5 times, and bearing capacity is increased to about 10 times.
Description
Technical field
The invention belongs to the line slideway auxiliary technical field, be specifically related to a kind of radially heavy-load type roller line slideway auxiliary.
Background technology
Along with Digit Control Machine Tool just fast towards large-scale, heavily loaded, at a high speed, low noise and respond fast future development, the linear rolling guides that the active demand bearing capacity is higher, rigidity is stronger such as numerical control gantry mill, numerical control floor boring, Large Machining Center, large-scale special equipment are supporting with it.
What in machinery industry, usually adopt at present is traditional ball line slideway auxiliary, and its structure is: slide and guide rail respectively have four arc raceways, relies on ball to support therebetween, and ball contacts as the some contact with roller surface.Advantage is that frictional force is little, sensitivity and precision high, be suitable for small size precise machine tool and use.Shortcoming is that the contact rigidity is poor, and bearing capacity is little, can not meet the needs of large-size numerical control machine and electromechanical integrated product.
Summary of the invention
The radially heavy-load type roller line slideway auxiliary that the object of the invention is to overcome the defect of above-mentioned prior art and a kind of super-heavy load, high rigidity are provided.
For achieving the above object, the present invention adopts following technical scheme:
A kind of radially heavy-load type roller line slideway auxiliary, comprise guide rail and slide, and described slide top is provided with that a row roller guide groove and lists raceway, bilateral symmetry is provided with two row and sidewinders; The roller that bears radial pressure load is arranged in described upper raceway, the roller that bears lateral pressure load is arranged in described sidewindering by retainer, described roller is the cylinder that two ends have convex shoulder, and described roller and described upper raceway and the roller surface sidewindered are that line contacts.
The contact wire and the horizontal line that bear the roller surface of the described roller of radial pressure load and described upper raceway are an angle of 90 degrees, bear the described roller of lateral pressure load and contact wire and the horizontal line of the described roller surface sidewindered and are miter angle.
The two ends of described slide are fixed with for making the back device of described roller shuttling movement.
Be provided with intubate in the back passage of described slide.
The end of described back device is connected with the end sealing that prevents that dust and break flour from entering.
Described back device is provided with lubricator cup.
The rolling element of line slideway auxiliary of the present invention is due to the roller with convex shoulder that adopts three row to contact with the raceway upper thread, but make roller easy motion in raceway, can bear the active force of each side up and down, and make the contact surface abrasion of roller and raceway little, long service life, thereby make described line slideway, contact rigidity between slide and rolling element three can be increased to 5 times of left and right than traditional product, bearing capacity is increased to 10 times of left and right, be more suitable for requiring good rigidly, the Digit Control Machine Tool that bearing capacity is large and the needs of electromechanical integrated product, assembling simultaneously easily, and the characteristics that interchangeability is arranged.
The accompanying drawing explanation
Figure 1 shows that the cross section structure schematic diagram of the radially heavy-load type roller line slideway auxiliary that the embodiment of the present invention provides;
Figure 2 shows that the perspective view of the radially heavy-load type roller line slideway auxiliary that the embodiment of the present invention provides.
The specific embodiment
Below, in conjunction with example, substantive distinguishing features of the present invention and advantage are further described, but the present invention is not limited to listed embodiment.
Shown in Fig. 1～2, this Fig. 1～2 show the structure of a kind of radially heavy-load type roller line slideway auxiliary that the embodiment of the present invention provides.For convenience of explanation, only show the part relevant with the embodiment of the present invention.
Refer to Fig. 1～2, a kind of radially heavy-load type roller line slideway auxiliary, comprise guide rail 1 and slide 2, and described slide 2 tops are provided with that a row roller guide groove and lists raceway, bilateral symmetry is provided with two row and sidewinders; The roller 3 that bears radial pressure load is arranged in described upper raceway, the roller 4 that bears lateral pressure load is arranged in described sidewindering by retainer 5,6, described roller 3,4 is the cylinder that two ends have convex shoulder, and described roller 3,4 and described upper raceway and the roller surface sidewindered are that line contacts.
The described shape of bearing the roller 3 of radial pressure load of the shape of described roller guide groove is complementary.
Preferably, close-packed arrays between each adjacent roller of a plurality of described rollers 3,4, i.e. each roller top-stitching contact is arranged.
Preferably, the contact wire and the horizontal line that bear the roller surface of the described roller of radial pressure load and described upper raceway are an angle of 90 degrees, bear the described roller of lateral pressure load and contact wire and the horizontal line of the described roller surface sidewindered and are miter angle.
Further, the two ends of described slide 2 are fixed with for making the back device 7 of described roller 3,4 shuttling movements.
Further, the outboard end of described back device 7 is connected with the end sealing 8 that prevents that dust and break flour from entering.
Further, on described back device 7, (two side ends) is provided with greaser.
Further, be provided with intubate 6 in the back passage of described slide 2.
Set up the passage be complementary with described shape of bearing the roller 4 of lateral pressure load in described intubate 6.
The rolling element of line slideway of the present invention has replaced ball by the roller with convex shoulder, and roller is tight-arranged in raceway, thereby makes roller in the raceway motion steadily, can bear the active force of each side up and down; And roller and raceway contact surface abrasion are little, extended service life, thereby can make the contact rigidity between described line slideway, slide and rolling element three be increased to 5 times of left and right than traditional product, bearing capacity is increased to 10 times of left and right, Digit Control Machine Tool that good rigidly, bearing capacity are large and the needs of electromechanical integrated product have been more suitable for requiring, in addition, the present invention assembles easily, and interchangeability is arranged.
