Description
Technical Field
The utility model relates to a fan equipment technical field, in particular to fan, motor element and centrifugal friction clutch thereof.
Background
In the fan, a motor is connected with an impeller, and the impeller is driven to rotate by the operation of the motor. When the single-phase motor is started in an on-load mode, the rotational inertia of the impeller is large, but the starting torque of the motor is small and the fluctuation is large, so that the motor is vibrated and noisy when being started, and even the motor is failed to start seriously.
The single-phase motor on-load starting method generally uses a friction starting device to rotate the motor and then gradually drive the impeller to rotate. Currently, a friction starting device consists of an arc-shaped plate and an annular spring. The plurality of arc plates are arranged on the impeller and positioned on the same circle, and the annular spring surrounds the outer sides of the plurality of arc plates; the end of the rotating shaft of the motor extends into a hole formed by the arc plates. As the rotating shaft of the motor rotates, the annular spring applies constraint force to the arc plates so as to generate friction force between the arc plates and the rotating shaft. However, the friction force generated by such a structure does not change much with the increase of the rotation speed, which is not beneficial to adjusting the rotational inertia and the starting load torque at different rotation speeds, and the vibration and the starting failure condition existing when the motor is started cannot be effectively improved.
Therefore, how to reduce the rotational inertia and the start load torque received when the rotating shaft is started, and reduce the damage of the vibration noise and the motor start failure is a problem to be solved urgently by those skilled in the art.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a centrifugal friction clutch to reduce the rotational inertia and the start load torque that receive when the axis of rotation starts, reduce the harm of vibration noise and motor start failure. The utility model also discloses a motor element and fan with above-mentioned centrifugal friction clutch.
In order to achieve the above object, the utility model provides a following technical scheme:
a centrifugal friction clutch comprising:
a first friction member for fixing to the rotating shaft;
a support portion for fixing to the rotating shaft;

and the friction connecting piece is arranged between the first friction piece and the supporting part and used for positioning the impeller in the circumferential direction, when the supporting part rotates along with the rotating shaft, the free end of the centrifugal arm moves outwards in the radial direction under the action of centrifugal force and drives the cam part to rotate, and when the cam part rotates, the friction connecting piece is pressed towards the first friction piece.
Preferably, in the above centrifugal friction clutch, the friction connecting member includes a second friction member fixed thereto, the second friction member being adapted to abut against the cam portion.

The embodiment of the utility model provides a fan is still provided, including impeller and motor element, motor element is as above-mentioned arbitrary motor element.
Preferably, the motor assembly further includes a limiting member disposed on the rotating shaft of the motor and used for limiting the axial movement of the impeller, and the limiting member is located on a side of the centrifugal friction clutch facing away from the main body of the motor.
The utility model provides a centrifugal friction clutch, when the motor starts, first friction piece and supporting part rotate along with the axis of rotation. When the rotating speed of the rotating shaft is low, the centrifugal force applied to the free end of the centrifugal arm of the centrifugal device is low, and the radial outward displacement of the free end is low, so that the rotating angle of the cam part relative to the supporting part is small, the pressing force of the cam part on the friction connecting piece is low, the pressure between the friction connecting piece and the first friction piece is low, the friction force between the friction connecting piece and the first friction piece is low, and the friction connecting piece slides relative to the first friction piece (and the rotating shaft); with the increase of the rotating speed of the rotating shaft, the centrifugal force applied to the centrifugal arm of the centrifugal device is increased rapidly, the centrifugal arm is displaced outwards in the radial direction under the action of the centrifugal force to be increased, and meanwhile, the cam part is driven to rotate by taking the supporting shaft as the center. Thereby the cam increases the support pressure to the friction connecting piece gradually, the pressure that the cam portion applyed in the friction connecting piece has been improved, and, pressure is passed to first friction spare by the friction connecting piece, effectively increase the frictional force between friction connecting piece and the first friction spare, along with the rotational speed of motor improves, the pressure that the cam portion applyed in the friction connecting piece increases gradually, and then the frictional force between friction connecting piece and the first friction spare also increases gradually, when frictional force reaches enough big, the friction connecting piece is driven synchronous revolution by first friction spare, the impeller is static relatively with first friction spare promptly, make the axis of rotation drive the load wheel and rotate with the same speed.
Through the structure, when the motor is started (the rotating speed of the rotating shaft is low), the friction force between the friction connecting piece and the first friction piece is small. Because the impeller is in a static state when the motor is started, the first friction piece and the friction connecting piece form a sliding friction pair. Because the impeller is connected with the friction connecting piece in a circumferential positioning mode, the first friction piece and the impeller can slide relatively. When the rotating speed of the rotating shaft of the motor is increased, the friction force between the friction connecting piece and the first friction piece is increased under the action of the cam part.

The utility model provides a centrifugal friction clutch, centrifugal device's cam portion exerts the extrusion force to the friction connecting piece, and this extrusion force is the proportion with the centrifugal force of centrifugal arm. Therefore, the friction force between the friction connecting piece and the first friction piece is proportional to the square of the rotating speed of the rotating shaft, and when the rotating speed is low (the motor is started), the friction connecting piece and the first friction piece slide relatively, so that the impeller and the first friction piece slide relatively, the rotating inertia and the starting load torque of the rotating shaft are reduced, the vibration noise when the motor is started is reduced, and the condition of starting failure is avoided.
The utility model provides a motor element and fan has above-mentioned centrifugal friction clutch, also should have same technological effect, no longer states in a tired manner one by one here.

The embodiment of the utility model provides a centrifugal friction clutch, including first friction piece 21, friction connecting piece 22, supporting part 23, centrifugal device 24 and back shaft 25.
The first friction piece 21 and the supporting part 23 are fixed on the rotating shaft 11 of the motor 1; the centrifugal device 24 includes a cam portion 241 and a centrifugal arm 242 fixedly connected to the cam portion 241, and the cam portion 241 is hinged to the support portion 23 via the support shaft 25, so that the cam portion 241 can rotate about the axis of the support shaft 25. The highest point of the cam portion 241, i.e., the position corresponding to the maximum thickness of the outer surface of the cam portion 241 to the rotation shaft thereof, is located on the side of the axis of the support shaft 25 away from the center of the support portion 23 in the initial state. The friction coupling 22 is arranged between the first friction element 21 and the support portion 23, by which arrangement, when the support portion 23 rotates with the rotating shaft 11, the free end of the centrifugal arm 242 of the centrifugal device 24 moves radially outward under the influence of centrifugal force, and at the same time, the cam portion 241 is rotated, and the cam portion 241 presses the friction coupling 22 against the first friction element when rotated. The friction connecting piece 22 is a connecting piece directly or indirectly fixedly connected with the impeller 3, or the friction connecting piece 22 and the impeller 3 can be integrated or the friction connecting piece 22 can be directly used as the impeller 3, and only the circumferential positioning of the friction connecting piece 22 and the impeller 3 is required to be ensured.
The embodiment of the utility model provides a centrifugal friction clutch, when motor 1 starts, first friction member 21 and supporting part 23 rotate along with axis of rotation 11. When the rotation speed of the rotating shaft 11 is low, the centrifugal force applied to the free end of the centrifugal arm 242 of the centrifugal device 24 is low, and the displacement of the free end outward in the radial direction is low, so that the rotation angle of the cam portion 241 relative to the support portion 23 is small, the force of the cam portion 241 against the friction connecting piece 22 is low, the pressure between the friction connecting piece 22 and the first friction piece 21 is low, the friction force between the friction connecting piece 22 and the first friction piece 21 is low, and the impeller 3 is circumferentially positioned and connected with the friction connecting piece 22, so that the friction connecting piece 22 slides relative to the first friction piece 21 (and the rotating shaft 11); as the rotation speed of the rotating shaft 11 increases, the centrifugal force applied to the centrifugal arm 242 of the centrifugal device 24 increases rapidly, and the centrifugal arm 242 is displaced radially outward by the centrifugal force to increase, and at the same time, the cam portion 241 is rotated about the support shaft 25. Since the highest point of the cam portion 241 is located at a side of the axis of the support shaft 25, which is away from the center of the support portion 23, so that the highest point of the cam portion 241 is moved toward the friction coupling 22, thereby gradually increasing the pressing force against the friction coupling member 22, increasing the pressing force of the cam portion 241 on the friction coupling member 22, and the pressure is transmitted to the first friction member 21 by the friction connecting piece 22, the friction force between the friction connecting piece 22 and the first friction member 21 is effectively increased, the pressure applied to the friction connecting piece 22 by the cam part 241 is gradually increased along with the increase of the rotating speed of the motor 1, and then the friction force between the friction connecting piece 22 and the first friction piece 21 is gradually increased until the friction force is enough, the friction connecting piece 22 is driven by the first friction piece 21 to synchronously rotate, i.e. the impeller 3 and the first friction member 21 are relatively stationary, so that the rotating shaft 11 rotates the load wheel 26 at the same speed.
With the above configuration, when the motor 1 is started (the rotation speed of the rotating shaft 11 is low), the frictional force between the frictional coupling 22 and the first frictional member 21 is small. Since the impeller 3 is in a static state when the motor 1 is started, the first friction piece 21 and the friction connecting piece 22 form a sliding friction pair. Due to the circumferential positioning connection between the impeller 3 and the friction connecting piece 22, the first friction piece 21 and the impeller 3 slide relatively. When the rotation speed of the rotating shaft 11 of the motor 1 increases, the highest point of the cam portion 241 moves in a direction to approach the friction link 22, thereby increasing the frictional force between the friction link 22 and the first friction member 21. The relative sliding amount between the first friction member 21 and the impeller 3 is reduced until the two are relatively stationary, and the gradual increase of the rotation speed of the impeller 3 is realized. The embodiment of the present invention provides a centrifugal friction clutch, in which the cam portion 241 of the centrifugal device 24 applies an extrusion force to the friction connecting member 22, and the extrusion force is proportional to the centrifugal force of the centrifugal arm 242. Therefore, the friction force between the friction connecting piece 22 and the first friction piece 21 is proportional to the square of the rotating speed of the rotating shaft 11, and when the rotating speed is low (the motor 1 is started), the friction connecting piece 22 and the first friction piece 21 slide relatively, so that the impeller 3 and the first friction piece 21 slide relatively, the rotational inertia and the starting load torque of the rotating shaft 11 are reduced, the vibration noise when the motor 1 is started is reduced, and the damage of starting failure is avoided.
In order to increase the frictional force that friction connecting piece 22 received, the embodiment of the utility model provides a friction connecting piece 22 of centrifugal friction clutch is including being fixed in the second friction piece 28 on it, cam portion 241 and second friction piece 28 direct contact, along with the rotation of cam portion 241, the equal stable increase of frictional force between second friction piece 28 and the friction connecting piece 22 increases the effect of the frictional force that friction connecting piece 22 received.

The elastic member 27 is a spring, and has one end connected to the support portion 23 and the other end connected to the centrifugal arm 242. In this embodiment, the number of the elastic members 27 is one in order to simplify the structure. As shown in fig. 5, the elastic element 27 is an elastic ring sleeved outside the centrifugal arms 242. Under the action of centrifugal force, the plurality of centrifugal arms 242 stretch the elastic ring outward. The elastic ring can be a metal spring ring, a rubber ring or a plastic ring with high elasticity, which will not be described in detail herein.
The centrifugal arm 242 is provided at an outer side thereof with a receiving groove 2421, and the elastic member 27 is fitted in the receiving groove 2421.
