Abstract
The utility model discloses a double-faced fastening insert bearing. The double-faced fastening insert bearing comprises an inner ring and an outer ring, wherein the outer ring is sheathed outside the inner ring, the left side and the right side of the inner ring are respectively protruded out of the left end surface and the right end surface of the outer ring to form a left protruding part and a right protruding part which are mutually symmetrical, both the left protruding part and the right protruding part are provided with at least one group of jackscrew holes for loading jackscrews, and each group of jackscrew holes comprises three jackscrew holes which are uniformly distributed on the same cross section. The double-faced fastening insert bearing enables a shaft to be aligned at the center during working, so that a load in the axis direction can be evenly and reasonably transferred, thus the shaft eccentricity is avoided and the unbalance loading problem in the axis direction is solved; the service life of the bearing is prolonged; the pitch of each jackscrew is 0.2mm-0.3mm; and the outer surface of each jackscrew is coated with a nylon rope, so that the reliability of bearing locking is further improved.
Description
Technical field
The utility model relates to a kind of high-speed fan and uses the bearing with spherical outside surface field, a kind of two-sided fastening bearing with spherical outside surface that is in particular.
Background technique
Along with the national economy develop rapidly, subway, the tunnel, and the industry, the civil building that spread all over town and country all need ventilation equipment, the blower fan industry is high speed development thereupon.The bearing with spherical outside surface of usheing to seat is made up of bearing with spherical outside surface and bearing support.During use, can directly be installed on the host design position with bolt, main frame need not design bearing chamber, and is very convenient.Because these characteristics, make the bearing with spherical outside surface of usheing to seat obtain more and more widely application in this industry.Along with the development of blower fan industry, the user is more and more higher to bearing products precision, performance, life-span and diversification of varieties requirement, has been not content with the requirement to the bearing with spherical outside surface of generally usheing to seat, turns to the demand of the product low to precision height, noise, that the life-span is long.
Present existing high-speed fan has two classes with the bearing with spherical outside surface of usheing to seat, and a class is (as Fig. 3), and its internal diameter is that the cooperation of plus tolerance and axle is a Spielpassung, and the jackscrew 12 of assembling back bearing with spherical outside surface can be pushed axle 13 to cause eccentric shaft on one side.One class is (as Fig. 4), carry out fastening with 16 pairs of axles of lock sleeve 15, because lock sleeve 16 has certain thickness, so and jagged its barycenter of cartridge screw that is used for is not or not the center of axle 15, when high speed rotating, will there be certain centrifugal force, make bearing off-centre, and in order to join lock sleeve 16, the inner ring 14 of bearing is wanted the thin and groove milling of first car, will increase processing cost like this, and inner ring 14 easily causes cracking, and can make bearing asymmetric more outstanding after adding lock sleeve 16, easily causes the unbalance loading of axial direction during bearing load.
The model utility content
The utility model provides a kind of two-sided fastening bearing with spherical outside surface, and its purpose is to overcome the above-mentioned defective that existing bearing with spherical outside surface exists, and prolongs the working life of bearing, reduces the noise that bearing produces.
The technical solution adopted in the utility model is as follows:
A kind of two-sided fastening bearing with spherical outside surface, comprise inner ring, outer ring, described outer ring is sheathed on the outside of described inner ring, the and arranged on left and right sides of described inner ring protrudes from the left and right both ends of the surface of described outer ring respectively and forms left and right two bumps, described left and right two bumps are symmetrical, and be equipped with at least one group of top wire hole that is used to load jackscrew on left and right bump, every group of top wire hole all is made up of three top wire holes that are uniformly distributed on the same cross section.
Further improve as of the present utility model, described left and right bump respectively is provided with one group of top wire hole.
Further improve as of the present utility model, the tooth distance of described jackscrew is 0.2mm-0.3mm, and described jackscrew external layer is coated with nylon coating.
By above-mentioned description to model utility as can be known, compare with prior art, advantage of the present utility model is:
1, is uniform-distribution with one group of jackscrew of forming by three jackscrews on the radial cross section of the left and right bump of the utility model inner ring, makes axle can align the center when rotated, avoided the problem of eccentric shaft.
2, the left and right bump of the utility model inner ring is symmetrical, makes the transmission that the load of axial direction of axle can balanced and reasonable, thereby has solved the unbalance loading problem of axial direction, thereby reduces the noise of bearing the working life of having improved bearing.
3, the utility model modern design, simple and practical, be easy to processing and the technology cost low, do not use lock sleeve, reduced the accessory of bearing, reduced the bearing cost, have vast market prospect.
Description of drawings
Fig. 1 is a sectional structure schematic representation of the present utility model.
Fig. 2 is the sectional structure schematic representation of A-A direction in Fig. 1.
Fig. 3 is the sectional structure schematic representation that adopts the bearing with spherical outside surface of Spielpassung.
Fig. 4 is to use the sectional structure schematic representation of the bearing with spherical outside surface of lock sleeve.
Embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings.
As Fig. 1, shown in Figure 2, this is a kind of two-sided fastening bearing with spherical outside surface, comprise: outer ring 1, inner ring 2, this outer ring 1 is sheathed on the outside of this inner ring 2, also comprise: be uniformly distributed in the steel ball 3 between outer ring 1 and the inner ring 2, end ring 4, bearing sealed ring 5, jackscrew 6 on the inner ring, detent balls 7 on the outer ring, bearing half retainer 8, this rivet 9 and two-sided fastening axle 10 above bearing half retainer 8, left side on the above-mentioned inner ring 2, the right side protrudes from the left side of this outer ring 1 respectively, right both ends of the surface, and form left, right bump, left side on the inner ring 2, right bump is symmetrical, make the transmission that the load of axial direction of axle 10 can balanced and reasonable, thereby solved the unbalance loading problem of axial direction.
As shown in Figure 2, on the radial cross section of the left and right bump on the inner ring 2, be uniform-distribution with 6, three jackscrews 6 of three jackscrews and make axle 10 well align the center, avoided eccentric generation.
Above-mentioned only is embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all belongs to the behavior of invading the utility model protection domain.
