Abstract
The invention belongs to the technical field of linear guide rail pairs, and particularly relates to a radial heavy-load type roller sliding base. The radial heavy-load type roller sliding base comprises a sliding base body, a row of roller guide grooves and an upper rolling way face are arranged on the upper portion of the sliding base body, the roller guide grooves are used for bearing radial pressure loads, the two sides of the sliding base body are respectively provided with a row of side rolling way faces and a returning channel, and the side rolling way faces are used for bearing lateral pressure loads. The upper rolling way face and the side rolling way faces are planes which can make contact with rollers in a linear mode. According to the radial heavy-load type roller sliding base, the rolling way faces and rolling bodies (the rollers) are in linear contact, therefore, stiffness of the sliding base is greatly improved, the bearing capability of the sliding base is about 10 times that of a traditional product, and the contact stiffness is about 5 times that of the traditional product.
Description
Technical field
The invention belongs to the linear guide pairs technical field, be specifically related to a kind of radially heavy-load type roller slide.
Background technique
Along with numerical 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 device are supporting with it.
At present, in machinery industry, common slide is Ball slide, and its structure is: slide has four arc raceways, 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 object of the present invention is to provide a kind of bearing capacity height and the radially heavy-load type roller slide that contacts good rigidly, be intended to solve current Ball slide contact rigidity poor, the technical problem that bearing capacity is little.
For achieving the above object, the present invention adopts following technological scheme:
A kind of radially heavy-load type roller slide, comprise the slide body, described slide body top is provided with roller guide groove and the upper roller surface of row for bearing radial pressure load, the both sides of described slide body are respectively equipped with side roller surface and the back passage of row for bearing lateral pressure load, described upper roller surface with the side roller surface for being the plane that line contacts with roller.
Described upper roller surface is vertical with horizontal plane, and the angle between described side roller surface and horizontal plane is 45 degree.
The present invention radially the roller surface of heavy-load type roller slide with rolling element (roller) for line contacts, thereby greatly improved the rigidity of slide, its bearing capacity is 10 times of left and right of traditional product, the contact rigidity is 5 times of left and right of traditional product.
The accompanying drawing explanation
Figure 1 shows that the cross section structure schematic diagram of the radially heavy-load type roller slide that the embodiment of the present invention provides;
Figure 2 shows that the perspective view of the radially heavy-load type roller slide that the embodiment of the present invention provides.
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.
Refer to Fig. 1, a kind of radially heavy-load type roller slide, comprise slide body 1, described slide body 1 top is provided with roller guide groove 2 and the upper roller surface 3 of row for bearing radial pressure load, the both sides of described slide body 1 are respectively equipped with side roller surface 4 and the back passage 5 of row for bearing lateral pressure load, described upper roller surface 3 with side roller surface 4 for being the plane that line contacts with roller.
Described upper roller surface 3 is vertical with horizontal plane, and the angle between described side roller surface 4 and horizontal plane is 45 degree.
It should be noted that, described roller is the cylindrical body rollers of two ends with convex shoulder.
The present invention radially heavy-load type roller slide reaches roller surface by be provided with the roller guide groove that bears radial pressure load on the slide body, the both sides of slide body are respectively equipped with side roller surface and the back passage of row for bearing lateral pressure load, and upper roller surface with the side roller surface for being the plane that line contacts with roller, thereby make this slide contact rigidity and bearing capacity be greatly improved, its contact rigidity can be increased to 5 times of left and right, bearing capacity can be increased to 10 times of left and right, be more suitable for requiring good rigidly, the needs of the numerical control machine tool that bearing capacity is large and the product of electromechanical integration.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (2)
1. a heavy-load type roller slide radially, it is characterized in that, comprise the slide body, described slide body top is provided with roller guide groove and the upper roller surface of row for bearing radial pressure load, and the both sides of described slide body are respectively equipped with side roller surface and the back passage of row for bearing lateral pressure load; Described upper roller surface with the side roller surface for being the plane that line contacts with roller.
2. heavy-load type roller slide radially according to claim 1, is characterized in that, described upper roller surface is vertical with horizontal plane, and the angle between described side roller surface and horizontal plane is 45 degree.
