Abstract
The utility model provides a self-centering sliding bearing device for a cross flow fan, belonging to the technical field of a part of a cross flow fan. The self-centering sliding bearing device comprises a rubber seat, wherein the rubber seat is further internally provided with a self-centering sliding bearing, the rubber seat is internally provided with an arc positioning concave surface, the self-centering sliding bearing is externally provided with an arc positioning convex surface, the arc positioning concave surface at the inner side of the rubber seat is in contacted fit with the arc positioning convex surface at the outer side of the self-centering sliding bearing. Compared with the prior art, the self-centering sliding bearing device has the benefit effect that the self-centering sliding bearing is continuously and accurately positioned by the arc positioning convex surface thereof along with the continuous running of the cross flow fan after a steel needle is inserted into the self-centering sliding bearing, so that the center of the self-centering sliding bearing is kept to be coincident with the whole rotating center of the cross flow fan. Therefore, the self-centering sliding bearing device guarantees the axiality, reduces the noise of the fan coming from an end of the bearing, greatly improves the whole performance of the fan, and prolongs the service life of the fan.
Description
Technical field
The utility model is the self contering plain bearing arrangement, particularly a kind of self contering plain bearing arrangement that is used for cross flow fan
Background technique
Cross flow fan commonly used comprises that wheel member, device are subjected to rubber and steel shaft assembly, motor and the support of device on motor at the axle on the wheel member, the wheel member device is in ducting part, described ducting part side device has rubber base, is placed with sliding bearing in the rubber base.The existing glide bearing is a cylindrical body, no arc locating face, have only by rubber base inner bearing gear and control, along with the continuous running of cross flow fan, bearing can't be from alignment, can't eliminate from the noise that the bearing end spreads out of, after causing the long-time running of cross flow fan, the steel axle has noticeable wear, makes it the complete machine center and moves down, influence the performance of blower fan, reduced the life-span.
The model utility content
The purpose of this utility model is in the above-mentioned prior art, sliding bearing is a cylindrical body, continuous running along with cross flow fan, sliding bearing can't be from alignment, from the defective that the noise that the sliding axle socket end spreads out of can't be eliminated, the steel axle has noticeable wear, provide a kind of after the steel axle inserts the self contering sliding bearing, continuous running along with cross flow fan, make the whole rotating center of its center and cross flow fan be consistent, avoid noise to produce, avoid the noticeable wear of steel axle, be used for the self contering plain bearing arrangement of cross flow fan.
The technological scheme taked of the utility model is to achieve these goals: a kind of self contering plain bearing arrangement that is used for cross flow fan, comprise rubber base, also be provided with the self contering sliding bearing in the described rubber base, the rubber base inboard is provided with the arc alignment concavity, self contering sliding bearing arranged outside has arc location convex surface, and the arc location convex surface in the arc alignment concavity of rubber base inboard and the self contering sliding bearing outside is a contact matching.
The radian size and the shape of the convex surface contacting point, arc location in the arc alignment concavity of described rubber base inboard and the self contering sliding bearing outside are in full accord.
The convex surface contacting point, arc location in the arc alignment concavity of described rubber base inboard and the self contering sliding bearing outside in the main cross section, goes to upper and lower the dolioform camber line of symmetry.
Because the arc location convex surface in the arc alignment concavity of rubber base inboard and the self contering sliding bearing outside is a contact matching, that is to say, it is not tight especially that surface both cooperates, and the radian of surface both contacting point size and shape are in full accord, the cooperation of surface both is very good, and rubber parts has elasticity, after the steel axle inserts the self contering sliding bearing, continuous running along with cross flow fan, blower fan itself produces the trace vibration, the arc alignment concavity of rubber base inboard and the arc in the self contering sliding bearing outside are located between the convex surface, can also produce certain relative movement.The self contering sliding bearing utilizes this certain relative movement, at continuous capturing position, the whole rotating center of its center and cross flow fan is consistent.
Compared with prior art, the beneficial effects of the utility model are: after the steel axle inserts the self contering sliding bearing, continuous running along with cross flow fan, the self contering sliding bearing utilizes its arc circumferential registration convex surface at continuous capturing position, and the whole rotating center of its center and cross flow fan is consistent.When having guaranteed coaxality, reduce the noise that blower fan spreads out of from the bearing end, improved the overall performance of blower fan greatly, prolonged the working life of blower fan.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
As shown in Figures 1 to 3, a kind of self contering plain bearing arrangement that is used for cross flow fan, comprise rubber base 1, also be provided with self contering sliding bearing 2 in the described rubber base 1, rubber base 1 inboard is provided with arc alignment concavity 11, self contering sliding bearing 2 arranged outside have arc location convex surface 21, and the arc alignment concavity 11 of rubber base inboard is a contact matching with the arc location convex surface 21 in self contering sliding bearing 2 outsides.The arc alignment concavity 11 of described rubber base 1 inboard is in full accord with the radian size and the shape of convex surface 21 contacting points, arc location in self contering sliding bearing 2 outsides.The arc alignment concavity 11 of described rubber base 1 inboard is located convex surface 21 contacting points with the arc in self contering sliding bearing 2 outsides, in the main cross section, goes to upper and lower the dolioform camber line of symmetry.
During assembling, self contering sliding bearing 2 usefulness hands are gone in the rubber base 1, the arc alignment concavity 11 of rubber base 1 inboard is a contact matching with the arc location convex surface 21 in self contering sliding bearing 2 outsides, it is not tight especially that surface both cooperates, and the radian of surface both contacting point size and shape are in full accord, and the cooperation of surface both is very good.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
