Abstract
The utility model relates to a double-sealed retainer-ring cylindrical full roller-bearing assembly clamping fixture, which comprises an upper clamping fixture and a lower clamping fixture; the upper clamping fixture comprises a conical upper matrix, the upper-end diameter of the conical upper matrix is large than the lower-end diameter, the periphery on the lower end surface of the conical upper matrix vertically and downwards extends to form an inner-ring clamping ring, and the inside-diameter size of the inner-ring clamping ring is equal to the outside-diameter size at the upper end of the inner ring of an assembled bearing; a lifting handle, an upper end cover, the conical upper matrix and the inner-ring clamping ring are in a once-molded integrated structure; the lower matrix of the lower clamping fixture is provided with a conical assembling hole, the lower matrix is provided with an outer-ring clamping ring, and the inside-diameter size of the outer-ring clamping ring is equal to the outside-diameter size at the upper end of the outer ring of the assembled bearing; and the conical-surface angle of the conical upper matrix is equal to that of the conical assembling hole of the lower matrix, and the axial sizes of the conical upper matrix and the lower matrix are equal. Through the double-sealed retainer-ring cylindrical full roller-bearing assembly clamping fixture, the problem of difficulty in the assembly of a double-sealed retainer-ring cylindrical full roller-bearing is solved, the design structure and the assembling process of an auxiliary clamping fixture are simple, the service life of the bearing is prolonged, and the assembly efficiency is also improved.
Description
Technical field
The utility model relates to rolling bearing mounting technology field.Specifically relate to a kind of double-sealing back-up ring cylinder and completely adorn roller bearing assembling mold.
Background technique
Double-sealing back-up ring cylinder is completely adorned roller bearing (is example with NNTR0616VY-2ZL) and is used higher in temperature, on the bigger equipment of dust, for its project organization in working life that improves bearing: an outer ring, two inner rings, have two iron elastic packing back-up rings (the breach intersection of iron elastic packing back-up ring is placed and played seal action) on each inner ring and completely adorn roller, two iron elastic packing back-up rings of an inner ring assembling can't be accomplished under the situation of not assisting mold, if iron elastic packing back-up ring can only assemble one, dust and impurity enter bearing inside in the Sealing shield ring indentation, there, sealing effect is undesirable, shorten the working life of bearing greatly, bearing is often because sealing effect is not good, cause bag axle phenomenon, make the bearing premature damage.
The model utility content
The purpose of this utility model, provide a kind of double-sealing back-up ring cylinder and completely adorn roller bearing assembling mold, making double-sealing back-up ring cylinder completely adorn the roller bearing assembly problem is resolved, cylinder is completely adorned roller bearing has had the double-sealing back-up ring to improve the sealing of bearing, thereby prolonged the working life of bearing, had auxiliary mold also to improve Assembling Production efficient.
The technological scheme that adopts is:
A kind of double-sealing back-up ring cylinder is completely adorned roller bearing assembling mold, comprises mold and following mold; Last mold comprises carcass in handle, upper end cap and the taper, fixedlys connected with upper end cap in the handle lower end; The upper end diameter of carcass is greater than lower end diameter in the taper, and the lower end surface periphery of carcass has extended the inner ring snap ring vertically downward in the taper, and the internal diameter size of inner ring snap ring is identical with the inner ring upper end outside dimension that is assembled bearing; Carcass and inner ring snap ring are one-time formed overall structure in handle, upper end cap, the taper; The following carcass of following mold has the taper pilot hole, and the lower end surface periphery of following carcass has extended the outer ring snap ring vertically downward, and the outer ring snap ring is the once-through overall structure with following carcass, and the internal diameter size of outer ring snap ring is identical with the outside dimension that is assembled the bearing outer ring upper end; The conical surface angle of carcass is identical with the conical surface angle of the taper pilot hole of following carcass in the taper, and carcass is identical with the axial dimension of following carcass in the taper.
During assembling, following carcass is arranged on and is assembled the bearing outer ring upper end, and be assembled the bearing outer ring upper end and insert in the snap ring of outer ring, the taper pilot hole of carcass under carcass is packed under the taper, insert in the inner ring snap ring 6 the inner ring upper end that is assembled bearing; The double-sealing check ring and the following carcass inner conical surface of inner ring assembly parts that are assembled bearing are guide surface, by carcass active force in the taper double-sealing check ring and inner ring assembly parts are packed in the alveolus of outer ring, reach the purpose of assembling.
The beneficial effects of the utility model are, double-sealing back-up ring cylinder is completely adorned the roller bearing assembling and is finished assembly process by auxiliary mold, solve double-sealing back-up ring cylinder and completely adorned the difficult problem of roller bearing assembling, auxiliary mold project organization and assembly process are simple, but prolonged the working life of bearing, also improved efficiency of assembling.
