Detailed description of the invention
In order to make the present invention clearly understand, below in conjunction with accompanying drawing, this device being described in detail, specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Embodiment one, as shown in Figure 1, Figure 2 and Figure 3, torque protection automobile air conditioner compressor driver is crossed in a kind of shock resistance provided by the invention, and including belt wheel 1, installation bearing 7 belt wheel 1 in, be all connected an annular catch 8 at the two ends of bearing 7.Described belt wheel 1 connects the flower keyboard 2 being made up of sleeve pipe 2a and ring flange 2b, and sleeve pipe 2a is arranged in the centre bore of belt wheel 1, and sleeve pipe 2a is connected with compressor main shaft by spline.
In conjunction with shown in Fig. 4 and Fig. 5, an annular bottom plate 3 is riveted by rivet 9 in the side of described belt wheel 1, a circular resigning hole 3c it is provided with at the center of annular bottom plate 3a, at the side circumference uniform distribution three of annular bottom plate 3a to riser 3b, the upside of each riser 3b is equipped with a flap 3d, the all outward-dipping bending setting of each flap 3d, arbitrary neighborhood two is to being equipped with an arc-shaped slot 3a on the annular bottom plate 3 between riser 3b.The limiting plate 3e of uniform three arcs in the inner side of resigning hole 3c, each limiting plate 3e is all extended to the side of annular bottom plate 3, and limiting plate 3e and riser 3b is separately positioned on the both sides of annular bottom plate 3, and limiting plate 3e is spacing with the centre bore of described belt wheel 1 coordinates, limiting plate 3e can effectively prevent described reed 3 play on described belt wheel 1, it is simple to the installation of annular bottom plate 3 is with fixing.Riser 3b is formed by punch process, and each riser 3b all becomes 90 degree of settings with annular bottom plate 3a.When annular bottom plate 3 is riveted on belt wheel 1, resigning hole 3c step down cooperation corresponding to described sleeve pipe 2a, the major part of rivet 9 is positioned in the cannelure of belt wheel 1, and each rivet 9 is all correspondingly arranged between two riser 3b of two corresponding pairs.
Shown in Fig. 6, Fig. 7 and Fig. 8, three draw-in groove 2c of circumference uniform distribution on described ring flange 2b, ring flange 2b between any two draw-in groove 2c is equipped with a screw 2e, draw-in groove 2c is the arc-shaped slot structure that outside is provided with opening, is equipped with in the upside of each two sidewalls of draw-in groove 2c and the lozenges 2d of corresponding described flap 3d corresponding matching；Or draw-in groove 2c be outside close arc-shaped slot structure, also all be provided with in the upside of two sidewalls of draw-in groove 2c and the lozenges 2d of corresponding flap 3d corresponding matching, this programme is preferably the former described structure, described every couple of riser 3b all with corresponding described draw-in groove 2c interference fit.
In conjunction with shown in Figure 11 and Figure 12, a dust cover 4 is connected also by three screws 10 in the outside of described flower keyboard 2, dust cover 4 includes a circular top board 4a, the through hole 4b stepped down for compressor main shaft it is provided with at the center of described top board 4a, an annular coaming plate 4c it is additionally provided with in the outside of the side of top board 4a, the top board 4a being provided with coaming plate 4c side goes back the baffle plate 4d that circumference uniform distribution three is V-type folded structure, top board 4a goes back circumference uniform distribution three for fixing the installing hole 4e of screw 10, each baffle plate 4d is all correspondingly arranged between two risers 3 of corresponding pairs, and the every couple of described riser 3b all with corresponding described baffle plate 4d interference fit, this cooperation can robust driver moment of torsion.Top board 4a and coaming plate 4c is completely covered reed 3 and flower keyboard 2, plays effective dustproof effect.
Embodiment two, in conjunction with shown in Fig. 9 and Figure 10, described in embodiment one, draw-in groove 2c adopts following structure:
A, draw-in groove 2c are arranged on described ring flange 2b medial surface and the thickness that the degree of depth of draw-in groove 2c is less than ring flange 2b, and described draw-in groove 2c is the outside arcuate groove for opening.
B, draw-in groove 2c are arranged on ring flange 2b medial surface and the thickness that the degree of depth of draw-in groove 2c is less than ring flange 2b, and described draw-in groove 2c is the outside arcuate groove for sealing.
In above two structure, the structure of described baffle plate 4d cancelled by above-mentioned dust cover 4.
During engine rotation, rotated by belt drive belt wheel 1, while belt wheel 1 rotates, also driving annular bottom plate 3 to rotate, annular bottom plate 3 drives three riser 3b is rotated, deformation along with three couples of riser 3b, promoting flower keyboard 2 to rotate gradually, thus driving compressor main shaft to rotate, and then driving whole compressor assembly operation, while flower keyboard 2 rotates, rotation also followed by dust cover 4 thereon.
Operation principle is: when compressor instantaneous overload, and compressor main shaft rotates needs high torque.And now belt wheel 1 is still rotating, riser 3b is difficult to promote flower keyboard 2 to rotate, cause riser 3b resilience, because of baffle plate 4d and corresponding two riser 3b interference fit, riser 3b will extrude baffle plate 4d deformation when resilience, owing to the effect of power is mutual, a pressure will be fed back to riser 3b while baffle plate 4d deformation, thus promoting the instantaneous generation high torque of this driver, to contend with, compressor instantaneous overload is impacted so that driver is properly functioning.When compressor instantaneous overload is more serious or during main shaft locking; compressor main shaft rotates extremely difficult; the pressure that baffle plate 4d provides cannot promote riser 3b to promote flower keyboard 2 to rotate, and now riser 3b will skid off from draw-in groove 2c, along with the rotation of belt wheel 1; under the effect of flower keyboard 2; riser 3b is impacted and bending by flower keyboard 2, thus separating with flower keyboard 2, compressor quits work; then avoid belt damage or fracture, be effectively protected the normal operation of engine wheel system.
