In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 to 7, the automobile of the present invention includes a damper wheel 100 for a rotating body to be connected to a crankshaft of the automobile via a belt.
The belt pulley 1 is in interference fit with the pressure ring 2, and the shaft sleeve 4 is in interference fit with the rotating shaft 3. The damping ring 6 is fixedly clamped with the compression ring 2 along the radial direction. The fastening means of the present invention is not limited to interference fit.
The self-lubricating bearing 8 can cause relative movement between the pulley 1 and the sleeve 4 and the shaft 3.
The damping sleeve 7 outside the damping ring 6 can increase the friction surface number and the friction area. The damping ring 6 and the compression ring 2 are fixed with each other in the rotating direction in a clamping mode. The material of the damping ring 6 can be nylon and the like. The damping sleeve 7 can be made of steel, aluminum, nylon and the like.
The protective sleeve 10 may be disposed between the rotating shaft 3 and the isolation spring 5, or between the isolation spring 5 and the bushing 4.
The damper wheel 100 for a rotary body according to the present invention is provided with the following two embodiments depending on the arrangement form of the vibration isolation spring of the spring main body 51.
The first embodiment is as follows:
as shown in fig. 2 to 5, in the present embodiment, the isolation spring 5 includes a spring main body 51, a first catch 52 extending in a radial direction from one end of the spring main body 51, and a second catch 53 extending in a radial direction from the other end of the spring main body 51.
The damping ring 6 is sleeved on the inner side of the rotating shaft 3.
The first clamping part 52 and the second clamping part 53 are respectively connected with the pressing ring 2 and the shaft sleeve 4. The compression ring 2 and the shaft sleeve 4 are respectively provided with a limiting groove used for clamping the first clamping part 52 and the second clamping part 53.
As shown in fig. 5, when the isolation spring 5 is in an uncompressed state, the damping sleeve 7 abuts against the isolation spring 5, and the force point of the isolation spring 5 is spaced from the first retaining portion 52 by 90 degrees in the circumferential direction. When the vibration reduction wheel 100 for the rotating body is in a static state, the first ring of the vibration isolation spring 5 is in surrounding contact with the damping sleeve 7, the torsion direction is a free state, the vibration isolation spring 5 is pre-compressed along the axial direction, and under the action of external moment, the vibration isolation spring 5 is twisted in the torsion direction, so that a positive pressure is generated for the damping ring 6 at the position where the first clamping part 52 and the damping sleeve form an included angle of 90 degrees to generate damping.
In this embodiment, when the bent axle passes through the belt and drags belt pulley 1 is with higher speed, the clamping ring 2 extrusion by interference fit the first card of isolation spring 5 is held the portion 52 and is extruded isolation spring 5, isolation spring 5 holds tightly the shrink, by the second card is held the portion 53 extrusion the axle sleeve 4, the rethread interference fit the pivot 3 drives the rotator rotor and rotates.
When the crankshaft drives the belt pulley 1 to decelerate, the rotating shaft 3 and the shaft sleeve 4 continue to accelerate due to the inertia effect, the vibration isolation spring 5 expands, and the rotating shaft 3 and the belt pulley 1 rotate relatively. The spring rate of the isolation spring 5 reduces the natural frequency of the system to well below the ignition frequency of idle speed, while the moment due to the load of the rotating body with the damper wheel 100 and the relative acceleration between the pulley 1 and the shaft 3 generates a pressure on the damping sleeve 7 at 90 ° to the first catch 52 of the isolation spring 5 and acts on the shaft 3 through the damping ring 6, which pressure causes a great frictional damping between the damping ring 6 and the shaft 3 and between the damping ring 6 and the damping sleeve 7.
Particularly under some extreme working conditions, the torque generated by the large torsion angle of the vibration isolation spring 5 is larger, so that larger friction damping can be generated, the damping can inhibit the speed fluctuation of the rotor under all orders, and the influence of the damping on an accessory system is reduced. When belt pulley 1 suddenly slows down, because isolation spring 5's inflation, pressure reduces, and frictional damping also correspondingly reduces, does benefit to pivot 3 with relative separation and reunion between the belt pulley 1 rotates.
The second embodiment:
as shown in fig. 6 to 7, the pressing ring 2 is provided with a first thread slope along the circumferential direction, the shaft sleeve 4 is provided with a second thread slope along the circumferential direction, and the first thread slope and the second thread slope are respectively abutted against two ends of the vibration isolation spring 5.
When the vibration isolation spring 5 is in an uncompressed state, the damping sleeve 7 abuts against the vibration isolation spring 5, and the stress point of the vibration isolation spring 5 and one end of the abutting end of the vibration isolation spring 5 and the pressing ring 2 are spaced by 90 degrees along the circumferential direction.
When the vibration reduction wheel 100 for the rotating body is in a static state, the first circle of the vibration isolation spring 5 is in encircling contact with the damping sleeve 7, the torsion direction is a free state, the vibration isolation spring 5 is pre-compressed along the axial direction, and under the action of external moment, the vibration isolation spring 5 is twisted in the torsion direction, so that a positive pressure is generated for the damping ring 6 at the position where one end, abutted against the compression ring 2, of the vibration isolation spring 5 and the damping sleeve form an included angle of 90 degrees, so as to generate damping.
The damping ring 6 is provided with a protruding part which is fixed with the pressing ring 2 in the rotating direction, so that the pressing ring 2 and the shaft sleeve 4 can rotate in a relative friction mode.
When the bent axle drags belt pulley 1 through the belt and accelerates, by with the 2 extrudions of clamping ring that 1 interference fit of belt pulley the one end of isolation spring 5, the expansion of isolation spring 5 pressurized, the other end extrusion axle sleeve 4, again through with 4 interference fit of axle sleeve 3 drive the rotor and rotate.
When the crankshaft drags the belt pulley 1 to decelerate, the rotating shaft 3 and the shaft sleeve 4 continue to accelerate due to the action of inertia, the vibration isolation spring 5 contracts, and the rotating shaft 3 and the belt pulley 1 rotate relatively. The spring rate of the isolation spring 5 reduces the natural frequency of the system to a frequency well below the idle ignition frequency, and at the same time, the moment generated by the load of the damper wheel 100 on the rotating body and the relative acceleration between the pulley 1 and the shaft generates a pressure on the damping sleeve 7 at a position 90 ° away from the isolation spring 5, which is the end where the isolation spring 5 and the press ring 2 abut against each other, and acts on the rotating shaft 3 through the damping ring 6, and this pressure generates a large frictional damping between the damping ring 6 and the rotating shaft 3 and between the damping ring 6 and the damping sleeve 7. When belt pulley 1 sharply slows down, because isolation spring 5's shrink, pressure reduces, and frictional damping also reduces correspondingly, does benefit to pivot 3 with relative separation and reunion between the belt pulley 1 rotates.
In the damper wheel 100 for a rotating body according to the present invention, when a speed difference is generated between the pulley 1 and the shaft, the damper ring 6 rubs against the wall surface of the rotating shaft 3. Because the moment generated by the deflection angle of the vibration isolation spring 5 acts on the damping ring 6 due to the load and the rotation angular acceleration of the vibration reduction wheel 100 for the rotating body, a positive pressure is generated at the position of the vibration isolation spring 5 separated by 90 degrees and acts on the damping ring 6, the positive pressure causes the relative friction between the damping ring 6 and the rotating shaft 3 to generate friction damping, and the damping can reduce the influence of the speed fluctuation of the rotational inertia of the rotating body on an engine accessory belt system.
According to the automobile and the vibration damping wheel 100 for the rotating body, the vibration isolation spring 5 is arranged, so that the natural frequency of the system can be reduced to be far lower than the idle ignition frequency by the vibration damping wheel 100 for the rotating body through the spring rate of the vibration isolation spring 5; by providing the damping ring 6, vibrations in all orders are damped by high damping. The application of high damping reduces the amplitude of the damping spring, which is beneficial to improving the durability and the service life of the damping wheel 100 for the rotating body.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
