Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and particularly relates to a transmission synchronization mechanism with a clutch. Background Technique

[0002] With the advancement of agricultural modernization, sowing machines and fertilizing and land preparation machines are increasingly widely used in agricultural production. The transmission systems of these mechanical devices need to have the capabilities of high efficiency and precise differential speed to adapt to different terrains and operation requirements. Especially under complex terrain conditions, as an important part of these machines, the performance of the chain drive system directly affects the operation quality and efficiency.

[0003] However, there are certain technical problems in the application of the existing chain drive system. In the current technology, the ratchet and pawl distribution is designed on the outer diameter or inner diameter, resulting in a small number of effective working teeth. The number of ratchet teeth cannot be distributed too much, otherwise the contact area of the ratchet teeth will be reduced, thereby reducing the service life. In addition, when the rotational speed difference between the two sides is small, the existing transmission system cannot achieve a synchronization effect, resulting in low transmission efficiency and unable to meet the requirements of precise differential speed, which to a certain extent limits the performance of sowing machines and fertilizing and land preparation machines. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the problems of low service life in the existing technology and the inability to achieve a synchronization effect and low transmission efficiency when the rotational speed difference between the two sides is small, and to provide a transmission synchronization mechanism with a clutch. The transmission synchronization mechanism with a clutch has the effects of improving transmission efficiency and the service life of the equipment, meeting different usage requirements, and solving problems such as non-synchronization.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A transmission synchronization mechanism with a clutch, including a first bearing and a second bearing, the first bearing and the second bearing are connected to each other through a second snap ring, fixed flanges are installed on the outer sides of both the first bearing and the second bearing, a ratchet sprocket is installed on the outer side of the second bearing, a fixed spline sleeve is installed on the inner side of the ratchet sprocket, a ratchet sliding sleeve is installed at one end of the outer side of the fixed spline sleeve, a separation sliding sleeve is installed on the outer surface of the ratchet sliding sleeve, and a first snap ring is installed at the outer end of the first bearing.

[0006] Preferably, a fixed pin is installed on the side surface of the ratchet sliding sleeve.

[0013] Compared with the prior art, the utility model provides a transmission synchronization mechanism with a clutch, having the following beneficial effects:

[0014] 1. By means of the axially multi-tooth structure provided by the utility model, the effective working number of teeth of the ratchet teeth is significantly increased, enabling all ratchet teeth to work simultaneously, thereby strengthening the average force on the ratchet teeth, solving the problems of uneven force and poor synchronization effect caused by uneven distribution of traditional ratchet teeth, and significantly improving the transmission efficiency and the service life of the equipment.

[0015] 2. By adding a clutch device, the utility model realizes the flexible separation of the transmission system, meeting different usage requirements. When the rotational speed difference on both sides is small, the clutch device can effectively solve the problem of non-synchronization, ensure the transmission efficiency of the seeding machine or the fertilizing and soil preparation machine during operation on various terrains, and improve the adaptability and reliability of the equipment.

[0027] Please refer to Figures 1-5, the present utility model provides a technical solution: a transmission synchronization mechanism with a clutch, including a first bearing 11 and a second bearing 14, which realizes stable connection and shock absorption between the bearings, ensures the smoothness of transmission. The first bearing 11 and the second bearing 14 are connected to each other through a second snap ring 13. Fixed flanges 1 are installed on the outer sides of both the first bearing 11 and the second bearing 14, providing reliable support and fixation, and ensuring the position stability of the entire transmission mechanism. A ratchet sprocket 2 is installed on the outer side of the second bearing 14, a fixed spline sleeve 7 is installed on the inner side of the ratchet sprocket 2, a ratchet sliding sleeve 3 is installed at one outer end of the fixed spline sleeve 7, and a separating sliding sleeve 5 is installed on the outer surface of the ratchet sliding sleeve 3, realizing the relative movement between the ratchet sliding sleeve 3 and the separating sliding sleeve 5, facilitating the clutch operation, and improving the flexibility of the operation. A first snap ring 10 is installed at the outer end of the first bearing 11. These two snap rings respectively limit the axial movement of the bearings, enhancing the stability of the transmission.

[0028] Preferably, a fixed pin 4 is installed on the side surface of the ratchet sliding sleeve 3. The fixed pin 4 fixes the position of the ratchet sliding sleeve 3, prevents its relative displacement during operation, and improves the reliability of the transmission.

[0029] Preferably, one end of the separating sliding sleeve 5 is snap-fitted with a third snap ring 6.

[0030] Preferably, a clutch spring 9 is installed inside the separating sliding sleeve 5.

[0034] Preferably, a number of through holes are penetrated on the surface of the fixed flange 1.

[0035] Working principle and usage process of the utility model: During use, first start the device. The connection between bearings ensures the smoothness of transmission, and the fixed flange 1 provides stable support. Then, by operating the clutch device, the ratchet sliding sleeve 3 and the separating sliding sleeve 5 move relative to each other to achieve the clutch operation. At this time, the clutch spring 9 and the tooth spring 8 work together to balance the impact force during clutch operation and extend the service life. Subsequently, the ratchet sprocket 2 drives the ratchet sliding sleeve 3 to engage with the ratchet spline sleeve. The axial multi-tooth structure enables all ratchet teeth to work simultaneously, improving the transmission efficiency and synchronous accuracy. During the operation of the device, if the rotational speed difference on both sides is small, the clutch device can effectively solve the out-of-sync problem and ensure the transmission efficiency of the seeding machine or the fertilizing and soil preparation machine during operation on various terrains. Finally, when stopping the device, operate the clutch device again to separate the transmission system, which is convenient for device maintenance and component replacement. The whole process is simple and efficient, ensuring the adaptability and reliability of the device in various operating environments.
