Description

TECHNICAL FIELD

[0001] The utility model relates to an actuator, especially a gear pneumatic motor actuator. BACKGROUND

[0002] The gear pneumatic motor actuator is a device that converts compressed air energy into mechanical motion, widely used in automation control systems. The core of this actuator is a gear type pneumatic motor, which drives the internal rotor to rotate by compressed air, outputting torque and rotary motion. The gear pneumatic motor actuator is favored for its compact structure, fast response speed, and simple maintenance, suitable for various industrial applications such as valve control, material handling, etc. They can reliably operate in harsh environments and have explosion-proof characteristics, especially suitable for occasions requiring precise control and frequent operation. By precisely controlling the flow and pressure of compressed air, the gear pneumatic motor actuator can achieve precise adjustment of the speed and direction of motion, ensuring efficient and reliable operation.

[0003] In the above-mentioned actuator, the transmission efficiency of the gear pneumatic motor may cause a series of problems, including energy waste, reduced response speed, insufficient output torque, increased maintenance cost, unstable operation, increased noise and vibration, and shortened equipment life. These problems not only affect the performance and reliability of the actuator, but also may cause additional environmental burden and economic cost. Therefore, improving the transmission efficiency of the gear pneumatic motor is crucial to ensure efficient operation of the system, reduce energy consumption, prolong equipment life, and reduce maintenance requirements, while also helping to reduce adverse environmental impacts. SUMMARY

[0004] In view of the deficiencies of the prior art, the utility model provides a gear pneumatic motor actuator for improving the transmission efficiency of the gear pneumatic motor.

[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: a gear pneumatic motor actuator, comprising a transmission system arranged in the gear pneumatic motor, the transmission system comprising a first transmission member and a second transmission member, the outer circumferential surface of the first transmission member and the second transmission member is uniformly provided with a first transmission part and a second transmission part along the circumference, respectively, the first transmission grooves for the second transmission parts to abut are formed between adjacent first transmission parts, the second transmission grooves for the first transmission parts to abut are formed between adjacent second transmission parts, the first transmission part and the second transmission part are respectively inclined from one end face of the first transmission member and the second transmission member to the other end face, so that there is always a first transmission part / second transmission part abutting on one side end face of the first transmission groove / second transmission groove during the rotation of the first transmission member and the second transmission member.

[0006] The utility model discloses a beneficial effect is: this kind of gear pneumatic motor actuator's design is through setting transmission part and transmission groove on first transmission piece and second transmission piece, the torque transmission efficiency of mechanism is improved obviously and the operating noise is reduced. The first transmission part and the second transmission part of oblique setting ensure that always have a transmission part abutting on the corresponding transmission groove one side end face in the rotation process, and such configuration increases the contact area when the first transmission piece and the second transmission piece rotate. The increased contact area not only improves the effect of torque conduction, but also helps to disperse the load, reduce the pressure on a single contact point, thereby reducing the gear wear, prolonging the gear life. At the same time, stable contact and uniform load distribution also help to reduce vibration, further reduce noise, make the actuator run more smoothly, improve the overall performance and reliability.

[0007] Further, the first transmission part is obliquely arranged so that a side end face of the first transmission groove is tapered from one end face of the first transmission piece to the other end face, and the other side end face of the first transmission groove is tapered from the other end face of the first transmission piece to one end face; the second transmission part is obliquely arranged so that a side end face of the second transmission groove is tapered from one end face of the second transmission piece to the other end face, and the other side end face of the second transmission groove is tapered from the other end face of the second transmission piece to one end face.

[0008] The design of the gear pneumatic motor actuator is characterized in that the first transmission part and the second transmission part are obliquely arranged so that one side end face of the transmission groove is tapered and the other side end face is expanded. This design not only maintains the size of the transmission groove, prevents the problem of difficulty in carrying large torque due to the small size of the transmission part, but also optimizes the force transmission path and improves the transmission efficiency. The tapered end face helps to reduce impact and noise in the initial stage of contact of the transmission part, and the expanded end face provides a larger contact area during transmission, enhancing the carrying capacity. Such a structure not only ensures the smoothness of transmission, but also improves the durability and reliability of the mechanism, so that the actuator can adapt to higher working load, prolongs the maintenance period and reduces the long-term operation cost.

[0009] Further, the first transmission part and the second transmission part have opposite oblique angles extending from one end face of the first transmission piece and the second transmission piece to the other end face.

[0010] The design of this gear pneumatic motor actuator ensures that the force transmission during transmission has high consistency, as the first transmission part and the second transmission part have the same inclination angle but opposite inclination directions. Due to the symmetry of the inclination angle, this design balances the force distribution, reduces additional stress and wear caused by uneven torque, and prolongs the service life of the transmission parts. The opposite inclination direction further ensures the torque transmission efficiency in different directions, so that the actuator can maintain stable performance in both forward and reverse motion. In addition, the symmetrical inclination design also helps to reduce vibration and noise, improve the smoothness and accuracy of transmission, which is particularly important for applications requiring high precision control. In summary, this design not only improves the reliability and durability of the actuator, but also enhances its stability and efficiency in dynamic operation.

[0011] Further, the first transmission part and the second transmission part are respectively provided with a first transmission shaft and a second transmission shaft at the center thereof in the axial direction, and transmission bearings are sleeved on the first transmission shaft and the second transmission shaft respectively located on both sides of the first transmission part and the second transmission part.

[0012] The design of the first transmission part and the second transmission part, by respectively providing a first transmission shaft and a second transmission shaft at the center in the axial direction, and sleeving transmission bearings on these shafts, realizes the optimization of structure and the improvement of performance. Such layout makes the transmission system more compact, while improving the transmission efficiency and stability. The transmission shafts and bearings located on both sides help to evenly distribute the load, reduce stress concentration on individual bearings, thereby reducing the wear rate and prolonging the service life of the bearings. In addition, this symmetrical configuration also helps to maintain the balance of the actuator, reduce vibration and noise caused by unbalanced load, so that the gear pneumatic motor runs more smoothly. This design enhances the durability and reliability of the actuator, making it suitable for more severe working conditions and a wider range of application scenarios, ensuring long-term stable operation and efficient energy transmission.
