Description

Technical Field

[0001] The utility model relates to the technical field of sprayer motors, in particular to a high-pressure airless sprayer motor counterweight wheel structure. Background Art

[0002] In the field of modern industrial equipment and mechanical design, the efficiency and stability of electric motors are crucial factors, especially in applications that require high precision and high stability, such as spray equipment. High-pressure airless sprayers are widely used in the coating industry and rely on efficient and stable motors to ensure spray quality and equipment reliability.

[0003] However, traditional high-pressure airless sprayers often experience motor-induced vibration and noise issues during use. These issues are primarily caused by motor shaft imbalance and improper motor design. Motor vibration during operation not only affects the uniformity and precision of the spraying effect, but also causes premature wear of the equipment, increasing maintenance costs. Furthermore, unstable motor current can also affect performance. Especially under large load fluctuations, the motor may be unable to effectively regulate its speed and torque, affecting overall operating efficiency and energy consumption. Utility Model Content

[0004] In response to the above-mentioned problems, the utility model provides a high-pressure airless sprayer motor counterweight wheel structure, which effectively solves the problems.

[0005] The utility model adopts the following technical solution: a high-pressure airless sprayer motor counterweight wheel structure, including a motor, a motor shaft is arranged in the motor, a counterweight wheel is arranged at one end of the motor shaft, the counterweight wheel includes a sleeve, the sleeve is sleeved on the motor shaft, a pin key hole is opened in the sleeve, a concave disc is arranged on the outer surface of the sleeve, a weighted ring block is arranged on the surface of the sleeve located on one side of the concave disc, a ring is arranged at one end of the sleeve located on one side of the concave disc, and a plurality of fan teeth are arranged on the outer surface of the concave disc.

[0006] Furthermore, the pin key hole is used to fix the sleeve and the motor shaft through a pin key.

[0007] Furthermore, the concave disc and the weighted ring block are made of high-density materials.

[0008] Furthermore, mounting legs are provided at the bottom of the motor.

[0009] Furthermore, shock-absorbing and buffering materials are provided at the bottom of the mounting legs.

[0010] Furthermore, the fan teeth are L-shaped.

[0011] The advantages of the present invention are that the counterweight wheel optimizes the weight distribution of the motor shaft, thereby reducing vibration caused by unbalanced rotating parts during high-speed rotation. By providing better mass balance, it helps the equipment maintain greater stability during operation and reduces equipment vibration. The reduced vibration helps the motor run more smoothly, thereby reducing current fluctuations. The counterweight wheel increases the rotational inertia of the motor shaft, allowing the motor to maintain a more stable speed in the face of load changes. This speed stability helps maintain current stability and avoid current fluctuations caused by sudden load changes. During the starting and stopping process, the presence of the counterweight wheel helps the motor transition more smoothly, reducing current peaks during startup and mechanical shock during shutdown, thereby improving overall energy efficiency and operating efficiency. The fan teeth on the counterweight wheel can generate additional airflow when the motor rotates, helping to effectively dissipate heat from the motor. This spontaneous heat dissipation mechanism helps maintain the motor at a suitable operating temperature, avoid overheating, and increase the lifespan and reliability of the motor.

[0018] See Figure 1-2 As shown, a high-pressure airless sprayer motor counterweight wheel structure includes a motor 1, a motor shaft 2 is provided in the motor 1, a counterweight wheel 3 is provided at one end of the motor shaft 2, the counterweight wheel 3 includes a sleeve 301, the sleeve 301 is sleeved on the motor shaft 2, a pin key hole 302 is opened in the sleeve 301, a concave disc 303 is provided on the outer surface of the sleeve 301, a weighted ring block 304 is provided on the surface of the sleeve 301 located on one side of the concave disc 303, a collar 305 is provided on one end of the sleeve 301 located on one side of the concave disc 303, and a plurality of fan teeth 306 are provided on the outer surface of the concave disc 303. The arrangement of the counterweight wheel 3 enhances the overall balance of the motor shaft 2, reduces the vibration caused by the imbalance of the shaft, thereby making the motor run more smoothly, and the reduction of vibration helps to make the motor run more smoothly, thereby reducing current fluctuations.

[0019] The key hole 302 is used to fix the sleeve 301 and the motor shaft 2 through the key, so as to ensure the secure installation of the counterweight wheel 3 and reduce the additional vibration caused by unstable installation.

[0020] The concave disc 303 and the weighted ring block 304 are made of high-density materials to increase the overall weight of the counterweight wheel 3, thereby improving stability during operation.

[0021] The bottom of the motor 1 is provided with mounting legs 4 to provide stable support, reduce the swaying of the whole machine during operation, and further reduce vibration.

[0022] The bottom of the mounting legs 4 is provided with shock-proof buffer material to effectively absorb the impact force and vibration generated during operation.

[0023] The fan teeth 306 are L-shaped, which enhances the airflow power generated when the counterweight wheel 3 rotates and cools the motor more effectively.

[0024] Working Principle: When the motor 1 rotates at high speed, unbalanced parts are prone to vibration. The counterweight wheel 3 reduces vibration by increasing the overall mass of the rotating parts and achieving better mass balance. This shock absorption effect helps the motor run more smoothly, extends the life of the machine, and reduces maintenance requirements. By improving the moment of inertia, the counterweight wheel 3 helps the motor 1 maintain a stable speed in the face of load changes. This directly affects the stability of the current, as the current demand of the motor 1 is closely related to its speed. A more stable speed means less current fluctuation and improved motor efficiency. The fan teeth 306 can effectively generate airflow when the counterweight wheel rotates, which not only provides a cooling effect for the motor, but also helps reduce performance degradation or damage that may be caused by overheating.
