Description

Technical Field

[0001] The utility model relates to a fixing structure of a fan damping ring. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas delivery machinery in China. The fans usually include ventilators, blowers, and wind turbines.

[0003] When assembling the motor and motor bracket of the fan, it is necessary to install a shock-absorbing ring to reduce the vibration generated when the motor moves; when installing the shock-absorbing ring, it is necessary to press down the shock-absorbing ring. When the shock-absorbing ring is subjected to downward external force, the bottom of the shock-absorbing ring will expand outward in diameter, causing the shock-absorbing ring to deform and easily cause the shock-absorbing ring to slip; and during transportation, the shock-absorbing ring is also likely to slip due to collisions during handling and other reasons. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a fixing structure for a fan damping ring, which reduces the influence of the force deformation of the damping ring and improves the reliability of the fan structure.

[0005] The technical solution to realize the utility model is as follows

[0006] A fixing structure for a fan damping ring comprises a motor bracket below the fan; three supporting bosses are evenly distributed on the motor bracket, and damping rubber rings are mounted on the supporting bosses; a fixing ring is arranged outside the supporting bosses; claws are arranged at corresponding positions of the fan and the damping rubber ring, and the claws are composed of a connecting block connected to the fan and a clamp on the connecting block.

[0007] A plurality of reinforcing ribs are evenly distributed on the top surface of the shock absorbing ring.

[0008] A clamping block protruding outward is provided on the inner wall surface of the clamp, and the clamping block extends from one end of the clamp opening to the other end of the clamp opening; and a clamping groove for the clamping block to be inserted is provided at the corresponding position of the shock absorbing ring and the clamping block.

[0009] The fixing ring and the supporting boss are integrally formed.

[0010] A chamfered structure transitions between the first inner hole above the shock absorbing ring and the second inner hole below the shock absorbing ring. A through hole is provided on the bottom surface of the shock absorbing ring, and an inner step is formed between the inner wall of the through hole and the inner wall of the second inner hole.

[0011] The height of the fixing ring is greater than the height of the inner step.

[0012] A screw with a flange is arranged in the center of the supporting boss.

[0013] The hardness of the fixing ring is greater than that of the shock absorbing ring.

[0014] By adopting the above technical solution, the bottom of the shock absorbing ring is restricted by the fixing ring. Since the fixing ring is not easy to deform, the expansion of the stress surface of the shock absorbing ring can be effectively prevented, thereby ensuring the shock absorbing effect, reducing the influence of the stress deformation of the shock absorbing ring, and improving the structural reliability of the fan.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] A fixing structure of a fan damping ring comprises a motor bracket 1 below the fan; three support bosses 2 are evenly distributed on the motor bracket, and a damping rubber ring 3 is mounted on the support boss; a fixing ring 4 is arranged outside the support boss; claws 5 are arranged at the corresponding positions of the fan and the damping rubber ring, and the claws are composed of a connecting block connected to the fan and a clamp 6 on the connecting block. The bottom of the damping ring is restricted by the fixing ring, and since the fixing ring is not easy to deform, it can effectively prevent the expansion of the stress surface of the damping ring, thereby ensuring the damping effect, reducing and minimizing the influence of stress deformation of the damping ring, and improving the reliability of the fan structure.

[0021] The top surface of the damping ring is evenly distributed with a number of reinforcing ribs 7 to strengthen the top surface structure and extend the service life of the damping ring.

[0022] The inner wall surface of the clamp is provided with a block 8 protruding outward, and the block extends from one end of the clamp opening to the other end of the clamp opening; the damping ring and the block are provided with a slot 9 for the block to be inserted into at the corresponding position. The block is inserted into the slot to assist in fixing the damping ring and limit its position.

[0023] The fixing ring and the supporting boss are integrally formed.

[0024] The first inner hole 10 above the shock absorbing ring and the second inner hole 11 below are transitioned by a chamfer structure, a through hole 12 is opened on the bottom surface of the shock absorbing ring, and an inner step 13 is formed between the inner wall of the through hole and the inner wall of the second inner hole. The screw with a flange is tightened onto the inner step to fix the shock absorbing ring.

[0025] The height of the fixing ring is greater than the height of the inner step, so that the damping ring can be subjected to a large restraining force in cooperation with the boss and the screw with flange, thereby preventing the damping ring from slipping off the supporting boss.

[0026] A screw 14 with a flange is provided in the center of the supporting boss. The flange cooperates with the inner step to limit the shock absorbing ring.

[0027] The hardness of the fixing ring is greater than that of the shock absorbing ring. The material of the fixing ring is consistent with that of the supporting boss, which facilitates one-piece molding and reduces production costs.
