Wherein, with decussation roller linear guide pairs, conventional art adopts steel plate or copper coin to carry out retainer impact briquetting, and from corrosion-resistant function, durability, cost each side is also not ideal enough, and using scope is limited.Further, the practical application usefulness in the Environmental Conditions that corrosivity is strong is not high.It is easily crooked that the retainer of this structural form also deposits in use roller, produces the bad phenomenon of self-locking.
And, adopt the decussation roller linear guide pairs of the retainer of this structural form also Problems existing be, two set of rails complete a set guiding pairs time, assembly spacing is comparatively large, and roller cannot contact completely with plane of trajectory orbital, is unfavorable for the load performance of raising guiding pairs.
Model utility content
The purpose of this utility model is, for above-mentioned deficiency, provides one can be used in heavy load and bad working environments, and the decussation roller linear guide pairs that operating noise is little.
For achieving the above object, technological scheme provided by the utility model is: a kind of decussation roller linear guide pairs, comprise two guide rails arranged in parallel, cross pin roller retainer assembly between the V-way groove being located at two guide rails, described cross pin roller retainer assembly comprises adaptive v-shaped track groove, and make the assembly spacing of two guide rails be less than or equal to the plastic cage of 0.2 millimeter, be located at equally distributed multiple roller on plastic cage, the medium position of described plastic cage is provided with the gear of rotation, the intersection of two planes that described v-shaped track groove intersects is provided with the tooth bar be meshed with gear.
Another preferred version of the present utility model, the contours profiles of the cross section of described plastic cage is square.
Another preferred version of the present utility model, described plastic cage is polyoxymethylene product.
Another preferred version of the present utility model, described gear is straight toothed spur gear, and the tip diameter size of gear is greater than the catercorner length size of the cross section of plastic cage.
The beneficial effects of the utility model are: compare conventional art, be provided with plastic cage, for the structural form of solid square bar shaped, quality is light and rigidity is strong, when assembly, plastic cage is used for the cylindrical side of roller and the plane of trajectory orbital of v-shaped track groove forms more surface of contact, be beneficial to the elastic deformation amount that roller reduces to exist, while realizing high rigidity, high load motion, the assembly spacing of two guide rails is less than or equal to 0.2 millimeter, assembly is tightr, delicate structure.
Operationally, because plastic cage is polyoxymethylene (POM) product, be beneficial to the utility model and realize coming and going straight line motion at a high speed, robust motion is excellent, and operating noise is low, and foreseeable, be beneficial to overall work life-time dilatation, cost is low.
The utility model is from corrosion-resistant function, and durability, the relative conventional art in cost aspect improves, for more tending to the design of environmental protection.Normally can use in the bad working environments that corrosivity is strong, practical application usefulness is high, and using scope is wide.Be beneficial to and widely use in medicine, food machinery.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
