Description

TECHNICAL FIELD

[0001] The utility model relates to the field of speed reducer mechanism especially relates to a kind of integrated drive control speed reducer mechanism. BACKGROUND

[0002] Speed reducer mechanism is a kind of mechanical device for reducing rotational speed and increasing torque, which is applied in many mechanical systems. Its main working principle is to achieve speed reduction through the combination of different gears, pulleys or other transmission components. For example, the common gear speed reducer mechanism is composed of multiple gears of different sizes. When the pinion drives the gear, according to the principle of gear transmission ratio, the rotational speed of the output shaft will be reduced, and the torque will be increased at the same time.

[0003] In pump valve structure, speed reducer mechanism plays many important roles. First, in some large centrifugal pump structures, the motor speed is often high, while the actual required speed of the pump impeller is low. The speed reducer mechanism can be installed between the motor and the pump shaft to ensure that the impeller rotates at the appropriate speed by reducing the speed. This helps to control the flow and lift of the liquid and avoid problems such as cavitation and excessive vibration caused by high speed. For reciprocating pumps, the speed reducer mechanism can adjust the movement speed of the piston. Because the high frequency of reciprocating pump piston movement may cause the frequent opening and closing of the valve group, which accelerates the wear of the valve. The speed reducer mechanism reduces the frequency of piston movement, allowing the inlet and outlet valves to open and close more smoothly, thereby prolonging the service life of the valve.

[0004] However, in actual pump valve structures, people often use a stepper motor as the driving source, and install an encoder on the outside of the lead screw to control its rotation. Therefore, the overall structure formed by the combination of the stepper motor, the encoder and the transmission lead screw occupies a large space. Moreover, the driving direction of the motor is the same as the direction of the lead screw, which requires the use of an additional transmission component to change the output direction when working in different environments. To solve the above problems, an integrated drive control speed reducer mechanism is proposed. SUMMARY
