Description

Technical Field

[0001] This invention relates to an automatic centering clutch, belonging to the field of power transmission, which enables synchronous transmission and engagement of power. Background Technology

[0002] Currently, in the field of mechanical transmission, devices involving power transmission and coupling primarily employ friction to achieve power coupling. This results in complex transmission structures and high manufacturing and maintenance costs. However, in some production activities, such as wastewater treatment plants, which often require low-speed, high-torque operating environments, this type of clutch is unsuitable. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic self-aligning clutch, which has a simple and reliable structure, is suitable for transmitting large torques, and can improve productivity.

[0004] The objective of this invention is achieved as follows: An automatic self-aligning clutch includes a motor, a reducer, a transmission sprocket, a cylinder mounting base, a cylinder, and a sliding bearing mounted on a base. A splined shaft is mounted on the base via the sliding bearing. The splined shaft engages with a driven sprocket mounted on a frame via a driven sprocket mounting base. The driven sprocket is slidably mounted on the splined shaft via a spline groove. The left end of the splined shaft forms a power output end, which includes a sleeve. A self-aligning shaft is mounted inside the sleeve via a compression spring. The outer end of the self-aligning shaft forms a conical head. The outer end face of the sleeve forms a meshing snap structure. The right end of the splined shaft... A set screw is used to fix a splined shaft retaining sleeve. A groove is provided inside the right end of the splined shaft, and a thrust bearing is fitted inside the groove. A spline sleeve is slidably fitted inside the splined shaft retaining sleeve. Splines are provided on the outer wall of the spline sleeve, and spline teeth are provided inside the splined shaft retaining sleeve. The splined shaft retaining sleeve mates with the spline sleeve. The spline sleeve is fixedly installed at the end of the piston rod of the cylinder and abuts against the thrust bearing. The cylinder and the splined shaft are arranged coaxially and fixedly installed on the right side of the machine base. A drive sprocket is provided at the end of the reducer shaft. The drive sprocket drives the driven sprocket to rotate the splined shaft through chain drive.

[0005] When the equipment starts working, the cylinder begins to operate. Simultaneously, the cylinder shaft generates axial thrust between the spline sleeve and the thrust bearing. At the same time, the spline shaft moves axially to the left via the spline sleeve and sliding bearing on the driven sprocket. The power output end of the spline shaft contacts the load end through a mandrel. Simultaneously, the driven sprocket's displacement is restricted by the sprocket mounting base and nylon bushing. Once the power output end contacts the load end, the motor starts working and transmits power from the reducer to the main drive sprocket. The main drive sprocket then transfers power to the driven sprocket via a chain. The driven sprocket then transmits power to the spline shaft via the spline sleeve, thus realizing the power output function of the main drive shaft. Afterward, the inclined grooves at the power output end and the load end begin to slide and engage, achieving the power transmission function.

[0006] Compared with existing technologies, the advantages of this invention are: 1. Simple equipment structure and long service life. 2. High system stability, capable of transmitting large torque, reliable operation, and not prone to slippage. 3. Low equipment investment. 4. Easy maintenance and repair. Attached Figure Description

Detailed Implementation

[0014] An automatic self-aligning clutch, such as Figures 1 to 5As shown, the system includes a motor 4, a reducer 5, a transmission sprocket 6, a cylinder mounting base 7, a cylinder 8, and a sliding bearing 3 mounted on a base 10. A splined shaft 14 is mounted on the base 10 via the sliding bearing 3. The splined shaft 14 engages with a driven sprocket 11 mounted on the base 10 via a driven sprocket mounting base 12. The driven sprocket 11 is slidably mounted on the splined shaft 14 via a spline groove. The left end of the splined shaft 14 forms a power output end 2, which includes a sleeve. A centering shaft 15 is mounted inside the sleeve via a compression spring 16. The outer end of the centering shaft 15 forms a conical head, and the outer end face of the sleeve forms a meshing snap structure 13. The meshing snap structure 13 is an existing structure. A spline shaft fixing sleeve 9 is fixed to the right end of the spline shaft 14 by a set screw. A groove is provided inside the right end of the spline shaft 14, and a thrust bearing 18 is fitted inside the groove. A spline sleeve 17 is slidably fitted inside the spline shaft fixing sleeve 9. A spline is provided on the outer wall of the spline sleeve 17, and a spline tooth groove is provided inside the spline shaft fixing sleeve. The spline shaft fixing sleeve 9 and the spline sleeve 17 are fitted together. The spline sleeve 17 is fixedly installed at the piston rod end of the cylinder 8 and abuts against the thrust bearing 18. The cylinder 8 is coaxially arranged with the spline shaft 14 and fixedly installed on the right side cylinder fixing seat 7 of the machine base 10. A transmission sprocket 6 is provided at the end of the shaft of the reducer 5. The transmission sprocket 6 drives the driven sprocket 11 to rotate the spline shaft 14 through chain drive.

[0015] Power engagement process: Power transmission is achieved through the engagement of the power output end 2 and the load end 1. During engagement: the conical head of the spindle 15 enables the mechanism to automatically align itself. Simultaneously, the spring 16 connected to the rear end of the spindle 15 reduces the impact on the spindle 15 during engagement and assists the mechanism in quickly disengaging and unloading power. Both the power output end 2 and the load end 1 employ a meshing snap mechanism, resulting in a smooth engagement process with minimal impact.

[0016] Axial and Radial Power Transmission Process: Axial Meshing Power Transmission: During operation, the splined shaft 14 moves axially along with the cylinder 8, while the driven sprocket 11 is restricted in displacement by the fixed seat 12, ensuring that the two sprockets are always in the ideal position during transmission. This not only achieves the system's power meshing function but also enables the motor 4 to carry power. Radial Motor Power Transmission: The motor power is input into the system through the sprockets, and the radial transmission function of the power is achieved by the spline sleeve of the driven sprocket 11 and the splined shaft 14, realizing the power transmission between the power output end 2 and the load end 1.

[0017] The cylinder thrust action process: Spline sleeve 17 is threadedly connected to the top of the cylinder 8 push rod. When the cylinder extends, the spline sleeve engages with the fixed end of the thrust bearing 18, generating an axial thrust to the left until the load end 1 contacts the power output end 2. At this time, cylinder 8 remains in the extended state. After the load end 1 contacts the power output end 2, the motor 4 starts to rotate, and the power is transmitted to the power output end 2 through the driven sprocket 11 and spline shaft 14. At this time, the spline shaft 14 starts to rotate with the motor 4, and the thrust bearing 18 starts to rotate. At this time, cylinder 8 will be in a fixed state along with the fixed end of the thrust bearing 18. When the power needs to be unloaded, the motor 4 first stops running, and then cylinder 8 begins to retract, driving the spline sleeve 17 to move to the right. After the spline sleeve 17 contacts the spline shaft fixed sleeve 9, it drives the spline shaft to move to the right, causing the power output end 2 to disengage from the load end 1, thus realizing the power unloading function.
