Abstract
The invention discloses a kind of damping type for axial flow blower to install cam, connection disc comprising a cylindric connection beam barrel and an annular, the circumference of described connection disc is provided with four disc circular holes, the damping lacquer disk(-sc) of an elasticity is provided between described connection disc and connection beam barrel, described damping lacquer disk(-sc) includes a cylindric packing element, the bottom of described packing element is provided with the rubber ring of an annular, the outer wall of described rubber ring is provided with the clamping gap of an annular, and described clamping gap is engaged with described connection disc.Connection disc is connected, and be connected using beam barrel is connected with the output shaft of motor by user using the disc circular hole connected on disc with the side wall of axial wheel.So, after motor starts, driving torque is transferred on connection disc by connection beam barrel by damping lacquer disk(-sc) so that axial wheel rotates.Due to using damping lacquer disk(-sc) passing power, operation noise is low, good damping effect.
Description
Technical Field
The invention relates to a fan damping device, in particular to a damping type mounting cam for an axial flow fan.
Background
On an air conditioner fan, an axial flow impeller is generally adopted for air supply. Generally, a connecting cam made of metal is respectively arranged at two ends of the axial flow impeller, and the connecting cam is directly and rigidly connected with the motor. When the connecting cam rotates, the connecting cam generates annoying noise due to vibration, and the comfort of the air conditioner fan is affected.
Disclosure of Invention
The invention mainly solves the technical problems in the prior art, and provides a damping type installation cam for an axial flow fan.
The technical problem of the invention is mainly solved by the following technical scheme:
the utility model provides a shock attenuation formula installation cam for axial fan, a serial communication port, a shock attenuation formula installation cam for axial fan contain a cylindric connecting shaft section of thick bamboo and an annular connection disc, the circumference of connecting the disc on be equipped with four disc round holes, connecting disc and connecting shaft section of thick bamboo between be equipped with an elastic shock attenuation rubber disk, shock attenuation rubber disk contain a cylindric packing element, the bottom of packing element be equipped with an annular ring gum, the outer wall of packing element on be equipped with an annular joint gap, the joint gap with the connection disc cooperate.
As a preferred embodiment of the invention, the connecting shaft cylinder and the connecting disc are both made of aluminum alloy, and the damping rubber disc is made of rubber.
The damping type mounting cam for the axial flow fan has the following advantages that: when the axial-flow impeller is used, a user connects the connecting disk with the side wall of the axial-flow impeller by using the disk circular hole on the connecting disk and connects the connecting disk with the output shaft of the driving motor by using the connecting shaft cylinder. Therefore, after the driving motor is started, the connecting shaft cylinder transmits the transmission torque to the connecting disc through the damping rubber disc, so that the axial flow impeller rotates. Because the damping rubber disc is adopted to transmit power, the running noise is low, the damping effect is good, and the damping rubber disc is particularly suitable for being used on an air conditioner fan. This a shock attenuation formula installation cam for axial fan simple structure, the effect is obvious, low cost, the practicality is strong.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention will be more clearly and clearly defined.
As shown in fig. 1 to 7, the shock-absorbing mounting cam 1 for an axial flow fan includes a cylindrical connecting shaft cylinder 3 and an annular connecting disc 2, four disc circular holes 21 are formed in the circumferential direction of the connecting disc 2, an elastic shock-absorbing rubber disc 4 is disposed between the connecting disc 2 and the connecting shaft cylinder 3, the shock-absorbing rubber disc 4 includes a cylindrical rubber cylinder 41, an annular rubber ring 42 is disposed at the bottom of the rubber cylinder 41, an annular engaging gap 43 is disposed on the outer wall of the rubber ring 42, and the engaging gap 43 is matched with the connecting disc 2.
The connecting shaft cylinder 3 and the connecting disc 2 are made of aluminum alloy, and the damping rubber disc 4 is made of rubber.
When in use, a user connects the connecting disc 2 with the side wall of the axial flow impeller by using the disc round hole 21 on the connecting disc 2 and connects the connecting shaft cylinder 3 with the output shaft of the driving motor. Thus, after the driving motor is started, the connecting shaft cylinder 3 transmits the transmission torque to the connecting disc 2 through the damping rubber disc 4, so that the axial flow impeller rotates. Because the damping rubber disc 4 is adopted to transmit power, the running noise is low, the damping effect is good, and the damping rubber disc is particularly suitable for being used on an air conditioner fan.
This a shock attenuation formula installation cam for axial fan simple structure, the effect is obvious, low cost, the practicality is strong.
Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
