Description

Technical Field

[0001] This utility model relates to the field of drive technology, and in particular to a drive mechanism for a screw rotor. Background Technology

[0002] In industries such as petroleum, chemical, pharmaceutical, and food processing, screw pumps and screw compressors are widely used due to their high efficiency and stable performance. One of the core components of these devices is the screw rotor, and the drive mechanism of the screw rotor is the key to realizing its rotational motion.

[0003] Confirm that key components such as the screw rotor, transmission device, and drive source are intact. Check that the connections between components are secure, especially easily loosened parts such as the drive chain and couplings. According to the equipment manual, correctly install the screw rotor drive mechanism, adjust the parameters of the transmission device, and check that the lubrication system is unobstructed. Press the start button to start the motor or other drive source. After confirming that the drive mechanism is operating normally, the load can be gradually increased to bring it into a stable operating stage. Use an encoder or other monitoring equipment to monitor the angular displacement or speed of the screw rotor in real time to ensure that it matches the preset value. After completing the work task, gradually reduce the load according to the requirements of the equipment manual until the machine stops completely.

[0004] The transmission mechanism of the existing device adopts a relatively traditional design, such as belt drive. There is friction between the belt and the pulley during the transmission process. This friction consumes some energy. Due to the elasticity of the belt, elastic slippage will occur during the transmission process, which further reduces the transmission efficiency. In addition, since the drive mechanism is designed as a whole, the belt will become thinner due to wear after long-term use. When replacing it, the staff may need to spend more time and effort to disassemble the entire drive mechanism. This not only increases the difficulty of maintenance work, but may also cause damage to other components due to improper operation during the disassembly process. Utility Model Content

[0005] In view of the aforementioned problem of low work efficiency, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drive mechanism for a screw rotor, comprising...

[0007] The enclosure has a processing cavity on its inner wall; fans are installed at both ends of the inner wall of the enclosure.

[0011] A screw is rotatably connected to the outer wall of the drive gear, and a rotor is rotatably connected to the outer wall of the screw.

[0014] Optionally, a connecting rod is slidably connected to the outer wall of the fixed column, and a cylinder that is fixedly connected to the rectangular plate is slidably connected to the inner wall of the connecting rod. A circular plate that is slidably connected to the outer wall of the tie rod is slidably connected to the inner wall of the mounting groove, and a spring is connected between the outer wall of the circular plate and the outer wall of the movable plate.

[0015] Optionally, the inner wall of the spindle is provided with a movable groove to facilitate the sliding connection of the moving plate, the outer wall of the driving gear meshes with a driven gear that is fixedly connected to the outer wall of the screw, the outer wall of the screw is slidably connected to a mounting block that is slidably connected to the machining cavity, and the outer wall of the rotor is slidably connected to the inner wall of the mounting block.

[0018] 1.

This eliminates the problems of slippage, wear and energy loss that may exist in traditional belt drives, and improves the overall transmission efficiency. In addition, since the engagement state of the drive gear and the main shaft can be flexibly controlled, the disassembly and maintenance process of transmission components is simplified, improving work efficiency, reducing maintenance costs and extending the service life of the equipment.

[0019] 2. By using two fans inside the enclosure to accelerate airflow, the heat inside the enclosure can be carried away more effectively, improving the heat dissipation efficiency of the drive mechanism. This ensures that even under long-term high-load operation, the drive mechanism can be kept in a relatively low-temperature environment, thereby avoiding performance degradation or failure due to overheating and improving the overall stability and reliability of the equipment.

Fans 25 are installed at both ends of the inner wall of the housing 1. There are two fans 25, which are divided into an intake fan and an exhaust fan.

[0029] The machining cavity is fixedly connected to the mounting plate 5, which is fixedly connected to the outer wall of the motor 6.
