Description

Technical Field

[0001] The invention relates to the technical field of high-precision gears, in particular to a self-lubricating high-precision gear shaft linkage device. Background Art

[0002] In the field of modern mechanical transmission, gear and pinion linkage devices are widely used in various types of mechanical equipment as core components. From daily industrial equipment to high-precision scientific research instruments, they are inseparable from it to realize the transmission of power and the conversion of motion. The gear and pinion linkage device accurately transmits the rotational motion of the power source to each working part through the mutual meshing between the gear and the pinion, thereby driving the equipment to complete various complex tasks. With the rapid development of science and technology and the increasing refinement of industrial production, the performance requirements of mechanical equipment are getting higher and higher, which makes the demand for self-lubricating high-precision gear and pinion linkage devices more urgent. High precision means that the equipment can complete the task more accurately, reduce errors and improve product quality. For example, in the field of precision machining, high-precision gear and pinion linkage devices can ensure the precise positioning of machining tools and produce parts that meet strict tolerance standards. The self-lubrication function is crucial. It can automatically provide lubrication for gears and pinion shafts during the operation of the equipment, reduce friction and wear, reduce energy loss, and extend the service life of the equipment. At the same time, self-lubrication can also reduce the tedious operation of manual lubrication, improve the automation level and operation efficiency of the equipment, and meet the needs of large-scale and high-efficiency production in modern industry.

[0003] However, the traditional gear and shaft linkage device has many shortcomings, which seriously restrict its application in modern high-end equipment. First of all, the lubrication method of traditional devices mostly relies on manual regular addition of lubricating oil, which is not only time-consuming and labor-intensive, but also difficult to ensure the timeliness and uniformity of lubrication. In actual production, manual lubrication often cannot accurately grasp the lubrication time interval and the amount of lubricating oil used, and is prone to insufficient lubrication or excessive lubrication. Insufficient lubrication will increase the friction between gears and shafts, accelerate component wear, reduce the service life of equipment, increase maintenance costs and downtime, and affect production efficiency. Excessive lubrication will cause waste of lubricating oil and may also cause environmental pollution problems. Secondly, the traditional device is also inaccurate in terms of accuracy. There are great limitations. Due to the limitations of manufacturing technology and assembly accuracy, as well as the influence of factors such as wear and thermal deformation during long-term operation, the transmission accuracy of traditional gear and shaft linkage devices will gradually decrease. This is a serious problem for modern industrial production with extremely high precision requirements, such as electronic chip manufacturing, aerospace parts processing and other fields. The reduction in accuracy will lead to unstable product quality, increased defective rate, increased production costs, and may even affect the performance and safety of the entire equipment system. In addition, traditional devices have poor adaptability when dealing with complex working conditions, and it is difficult to meet the requirements of modern mechanical equipment for stable operation under different environmental conditions and workloads. For this reason, we proposed a self-lubricating high-precision gear and shaft linkage device. Summary of the invention

[0014] Compared with the prior art, the present invention provides a self-lubricating high-precision gear shaft linkage device, which has the following beneficial effects: 1. This device effectively reduces the gap and error in the transmission process through the precise matching design between the gear ring, main gear shaft, gear plate and linkage shaft, such as the close fit between the trapezoidal connecting groove inside the main gear shaft and the gear plate connecting block, and the high-precision meshing between the linkage teeth and the gear plate. Under the same operating time and working conditions, the transmission accuracy of this device can be improved by more than 30% compared with the traditional device, which greatly reduces the frequency of equipment debugging and maintenance caused by transmission accuracy problems, ensuring that the equipment can operate stably and with high precision for a long time.

In some high-load equipment, traditional devices may have obvious tooth surface wear within 5000 hours due to poor lubrication. However, due to the self-lubricating function of this device, after running for 5000 hours under the same working conditions, the degree of component wear is still at a low level. This device can extend the service life of key components by more than 1-3 times, while greatly reducing the workload and frequency of manual lubrication maintenance, reducing maintenance costs, and improving the continuous operation time and production efficiency of the equipment.

[0016] 3.

At the same time, the sealing plate surrounds the outside of the through hole to ensure the good sealing of the device and prevent lubricating oil leakage. Compared with traditional devices, this device can reduce the leakage of lubricating oil by more than 95%, maintain a good lubrication environment inside the device, reduce the risk of equipment failure due to lubricating oil leakage, and improve the reliability and stability of equipment operation.

The function of the lubricating head is to accurately drip the lubricating oil delivered through the lubricating pipe onto key transmission parts such as the main gear shaft to achieve automatic and precise lubrication. The design of the lubricating head can control the dripping speed and position of the lubricating oil, ensuring that key transmission parts are fully and evenly lubricated, effectively reducing friction and wear between parts, and is the key executive component for the self-lubricating system to achieve precise lubrication.

[0045] Working principle: The power transmission effect is achieved by linking the main gear shaft 5 and the gear piece 6 through the gear ring 1. The gear ring 1 serves as the basic structure of the device. The main gear shaft 5 arranged on the inner side thereof penetrates the top cover 3 and the bottom cover 2, providing a main path for power transmission. The connecting groove 501 surrounding the main gear shaft 5 is a trapezoidal structure, which is connected to the gear piece 6 by riveting. When the gear ring 1 rotates under the action of external power, the main gear shaft 5 rotates accordingly due to the close fit with the gear ring 1. At this time, the connecting groove 501 interacts with the connecting block 601 on the inner side of the gear piece 6. Due to the adaptation of the two, the gear piece 6 can rotate synchronously with the main gear shaft 5, thereby transmitting the power of the gear ring 1 to the gear piece 6, realizing the power from the gear ring 1 to the gear piece 6, laying the foundation for the subsequent linkage with other components. The linkage shaft 7 is linked to the gear plate 6 to achieve a precise transmission effect. The outer side of the linkage tooth 701 arranged at the bottom of the linkage shaft 7 is meshed with the gear plate 6. When the gear plate 6 rotates driven by the main gear shaft 5, the linkage tooth 701 and the teeth of the gear plate 6 mesh with each other, so that the linkage shaft 7 rotates accordingly. Due to the high-precision characteristics of gear meshing transmission, the linkage shaft 7 can accurately follow the rotation of the gear plate 6 to achieve precise power output. This precise transmission ensures that the entire device can accurately transmit power according to the predetermined transmission ratio during operation, meeting the demand for high-precision transmission. The top cover 3, The main gear shaft 5 and the like achieve an automatic lubrication effect. The oil storage bin 802 arranged on the fixed plate 801 on the inner side of the mounting frame 4 has a one-way oil hole on its top to ensure that the lubricating oil flows into the oil storage bin 802 in one direction. One side of the oil storage bin 802 is connected to the oil head 804 through the oil pipe 803. One end of the oil head 804 extends to the bottom of the top cover 3. When the device is running, the lubricating oil flows from the oil storage bin 802 through the oil pipe 803 to the oil head 804, and drips from the oil head 804 to the bottom of the top cover 3, and then flows down along the main gear shaft 5 to provide lubrication for key parts such as the connection between the gear ring 1 and the main gear shaft 5, the connection between the main gear shaft 5 and the gear plate 6, and the meshing part of the gear plate 6 and the linkage tooth 701. This automatic The dynamic lubrication method effectively reduces the friction between the components, reduces wear, and improves the operating efficiency and service life of the device. The bottom cover 2 is linked to the liquid guide groove 201 and the sealing plate 202 to achieve the lubricating oil recovery and sealing effect. During the operation of the device, the excess lubricating oil flows along the main gear shaft 5 to the inside of the bottom cover 2. The liquid guide groove 201 surrounding the bottom of the bottom cover 2 can guide the excess lubricating oil to gather in one place for centralized treatment. At the same time, the through hole set at the bottom of the bottom cover 2 and the sealing plate 202 surrounding the outside of the through hole can not only discharge the lubricating oil when necessary, but also ensure the sealing of the device, prevent the leakage of lubricating oil, maintain the cleanliness of the internal environment of the device, and ensure the stable operation of the device.
