Describe in detail with reference to the accompanying drawings according to the utility model embodiment in the coupling 100 of air-conditioning draught fan.It should be noted that, two axles that coupling 100 can be used in connection different institutions make it jointly to rotate with transmitting torque.For convenience of describing, the axle of two in different institutions can be called the first axle (scheming not shown) and the second axle (scheming not shown).
As Figure 1-Figure 2, according to the coupling 100 for air-conditioning draught fan of the utility model embodiment, comprising: main body portion 10, spacer portion 20 and two axle sleeves 30.
Particularly, main body portion 10 has along the through chamber 11 of the central axis of main body portion 10.Such as, in example as shown in Figure 1, chamber 11 is (above-below direction as shown in Figure 1) through main body portion 10 along the vertical direction.Spacer portion 20 is located in chamber 11, with the axial direction along main body portion 10, chamber 11 is divided into the first chamber 111 and the second chamber 112.
Coupling 100 can also comprise two axle sleeves, 30, two axle sleeves 30 and be suitable for overcoat on both axes, and two axle sleeves 30 are located in the first chamber 111 and the second chamber 112 respectively, and the end face of two axle sleeves 30 is only against in the opposing sidewalls of spacer portion 20 respectively.Such as, as shown in Figure 1, the lower end surface being positioned at the axle sleeve 30 of top (above-below direction as shown in Figure 1) is only against on the sidewall of (above-below direction as shown in Figure 1) upward of spacer portion 20, and the upper-end surface being positioned at the axle sleeve 30 of below (above-below direction as shown in Figure 1) is only against on the sidewall of (above-below direction as shown in Figure 1) downward of spacer portion 20.
Alternatively, main body portion 10 and spacer portion 20 are respectively rubber parts.Thus, can manufacturing procedure be reduced, reduce cost of production.Further, main body portion 10 and spacer portion 20 are formed in one part.In other words, spacer portion 20 can be one-body molded on the inwall of the chamber 11 of main body portion 10.Such as, main body portion 10 and spacer portion 20 can pass through injection moulding integrated molding.In addition, two axle sleeves 30 respectively with chamber 11 sidewall interference fit.Meanwhile, for improving the connection reliability of two axle sleeves 30 and the first axle, the second axle, fastening piece (scheming not shown) can be passed through the first axle, the second axle are fastened on corresponding axle sleeve 30.Alternatively, fastening piece can be clamping bolt, and one end of clamping bolt is also only against on corresponding axle through main body portion 10, axle sleeve 30 successively.
For convenience of describing, the axle sleeve 30 being positioned at top (above-below direction as shown in Figure 1) is called the first axle sleeve, the axle sleeve 30 being positioned at below (above-below direction as shown in Figure 1) is called the second axle sleeve.First axle sleeve can be located in the first chamber 111, and is suitable for the one end being set in the first axle; Second axle sleeve 30 can be located in the second chamber 112, and is suitable for the one end being set in the second axle.In use, one end of the first axle stretches in the first chamber 111 coupling 100, and the first axle sleeve cuff is positioned at the part of the first chamber 111 on the first axle; One end of second axle stretches in the second chamber 112, and the second axle sleeve cuff is positioned at the part of the second chamber 112 on the second axle.
Wherein, the extending towards the central axis of main body portion 10 and exceed the inner circle wall of any axle sleeve 30 at least partially of spacer portion 20.In use, at least part of end face being positioned at the first chamber 111 of the first axle, at least part of end face being positioned at the second chamber 112 of the second axle are only against in the opposing sidewalls of spacer portion 20 coupling 100 respectively.Such as, as indicated with 1, the lower end surface of the first axle is only against on the sidewall of (above-below direction as shown in Figure 1) upward of spacer portion 20, and the upper-end surface of the second axle is only against on the sidewall of (above-below direction as shown in Figure 1) downward of spacer portion 20.Thus, can efficiently avoid coupling 100 in the process of connection two axles, the end of two axles is collided mutually.
In correlation technique, for avoiding the end of two axles to collide, usually all add rubber sleeve in the end of axle.Be understandable that, increase the complexity that rubber sleeve not only adds assembly technology difficulty, assembling, also add cost of labor simultaneously.In addition, rubber sleeve also easily comes off, thus reduces efficiency of assembling, have impact on using effect.And the coupling 100 for air-conditioning draught fan of the utility model embodiment not only has, and structure is simple, the advantage of easy processing, but also the problem that the end efficiently solving coupling 100 two axles in the process of connection two axles is collided mutually.
According to the coupling 100 for air-conditioning draught fan of the utility model embodiment, spacer portion 20 is utilized chamber 11 to be separated into the first chamber 111 and the second chamber 112, and the extending towards the central axis of main body portion 10 and exceed the inner circle wall of any axle sleeve 30 at least partially of spacer portion 20.Coupling 100 is when connection two axles, and at least part of end face being positioned at two axles of the first chamber 111 and the second chamber 112 is only against in the opposing sidewalls of spacer portion 20 respectively.Thus, reduce cost of production, the problem that the end efficiently solving coupling 100 two axles in the process of connection two axles is collided mutually.
As shown in Figure 2, in an optional example of the present utility model, spacer portion 20 can be space bar, and chamber 11 is separated into the first chamber 111 and the second chamber 112 of not conducting mutually by space bar.Thus, the end that efficiently avoid coupling 100 two axles in the process of connection two axles is collided mutually.
As shown in Figure 1, in another optional example of the present utility model, spacer portion 20 can be annular space portion, and chamber 11 is separated into the first chamber 111 and the second chamber 112 of mutual conduction by annular space portion.Thus, the end of coupling 100 two axles in the process of connection two axles not only can be avoided mutually to collide, but also alleviate the overall weight of coupling 100, thus reduce further cost of production.Further, for ensureing that the end of coupling 100 two axles in the process of connection two axles can not be collided mutually, the radial dimension of the inner ring of spacer portion 20 is suitable for the radial dimension being only against the end in spacer portion 20 being less than arbitrary axis.That is, the radial dimension at the position only supported with spacer portion 20 phase of the first axle and the second axle is all greater than the radial dimension of the inner ring of spacer portion 20.
Certainly, the shape of spacer portion 20 is not limited to this, and such as, according to an example of the present utility model, spacer portion 20 is multiple projections spaced apart along the circumferential direction of chamber 11.Thus, the overall weight of coupling 100 can be alleviated further, reduce cost of production.Further, for ensureing that the end of coupling 100 two axles in the process of connection two axles can not be collided mutually, in multiple projection lie farthest away two projections between distance be suitable for the radial dimension being only against the end in spacer portion 20 being less than arbitrary axis.That is, the radial dimension at the position only supported with spacer portion 20 phase of the first axle and the second axle is all greater than the distance between any two projections.
