Description

Technical Field

[0001] The present application relates to the technical field of transmission devices, and in particular to a planetary gear transmission device. Background Art

[0002] The planetary gear transmission is an efficient and compact power transmission device, which is widely used in modern industry and automation technology. Its unique structure and performance advantages make it stand out among many mechanical transmission devices.

[0003] After searching, the Chinese patent publication number CN102287510B discloses a new type of planetary gear transmission device. Although the planet carrier and the outer friction plate of the device are matched by splines, the planetary gear is supported on the planet carrier by two self-aligning ball bearings, the output shaft is supported on the right flange by two deep groove ball bearings, and the inner friction plate is separated by a disc spring, the beneficial effect is that it can not only achieve soft start and speed regulation, but also has the advantages of small size, compact structure, large load capacity, high transmission efficiency, stable operation, etc., and at the same time, low cost and convenient maintenance, but the device is not provided with an overload protection mechanism inside, which leads to overload causing the gear to bear stress beyond the design limit, resulting in gear deformation, tooth surface peeling, tooth root fracture and other failure forms, the bearing will also deform and fail due to the axial load and impact load generated by the overload, the pillar will break or desolder, and the shaft may be elastic-plastic deformed or even broken due to the strong torque;

[0004] After searching, the Chinese patent publication number CN119042306A discloses a lubricating oil circuit structure for a planetary gear transmission device. Although the device adopts a branched lubricating oil supply method to lubricate each component in turn, that is, the lubricating oil flows through the oil supply hole, the oil supply annular groove and the first lubricating oil inlet hole and then enters the first annular groove. The lubricating oil in the first annular groove enters the oil supply pipe and the sun gear injection pipe through the first lubricating oil outlet hole, thereby realizing efficient lubrication of the meshing surfaces of each gear, the sliding bearing and the journal, replacing the commonly used planetary carrier lubricating oil channel design. The coordination of the inlet hole, oil outlet hole and annular groove compensates for the loss along the way and reduces the oil supply capacity of the external oil station. However, due to the wear of the gears during long-term operation, more metal debris will be generated. Furthermore, the metal powder debris has a certain hardness and will circulate inside the equipment, pass through the gaps between parts, and cause abrasive wear, resulting in scratches, crushing and scrapes on the metal surface, and even metal fatigue. The metal powder will further wear the equipment, resulting in a decrease in the accuracy of key components such as gears and bearings, affecting the normal operation of the equipment and may even cause serious mechanical failures.

When the torque exceeds the set threshold, the positioning plate will retract backward through the inclined structure of the ratchet wheel, causing the ratchet wheel to slip on the surface of the positioning plate, thereby causing the planetary gear box to idle inside and protecting the main transmission device from damage due to overload stress.

The movement of the adjusting plate will compress or relax the second spring, thereby changing the pressure of the pressure plate on the positioning plate. This pressure adjustment mechanism enables the equipment to flexibly adjust the protection threshold of the anti-overload mechanism according to different working conditions and load requirements.

[0010] Preferably, the lubricating mechanism includes an oil storage tank, which is installed at the bottom of the main transmission device by bolts, the interior of the oil storage tank and the bottom of the interior of the main transmission device are filled with lubricating oil, a connecting groove is provided between the main transmission device and the oil storage tank, the connecting groove is used for communication between the main transmission device and the oil storage tank, a magnetic bar is provided at the bottom of the oil storage tank, a filter screen is provided outside the bottom of the connecting groove, the interior of the oil storage tank is divided into an upper and lower cavity by the filter screen, the oil storage tank is connected to the main transmission device through the connecting groove, the lubricating oil can flow freely between the two, so that the lubricating oil can be circulated in the main transmission device, ensuring that the transmission gear is always in a good lubricated state, the lubricating oil splashes in the main transmission device, evenly lubricates each gear, reduces friction and wear between gears, improves transmission efficiency and service life of equipment, and a magnetic bar is provided at the bottom of the oil storage tank, metal debris (such as iron filings) in the lubricating oil will be absorbed by the magnetic bar, which can effectively remove impurities in the lubricating oil and maintain the cleanliness of the lubricating oil.

[0013] Preferably, the circulation pipe is made of copper-aluminum composite material and has a spiral structure. Fins are mounted on the outside of the circulation pipe, and the fins are distributed in a circular shape with equal spacing. The outer wall of the fin is welded to the inner wall of the air deflector, and a fan is installed on the top of the air deflector. Both ends of the air deflector are open.

[0016] Compared with the prior art, the beneficial effects of this application are:

[0017] (1) During the operation of the device, the planetary gearbox drives the second transmission shaft to rotate, and the second transmission shaft further drives the positioning plate to rotate. The rotation of the positioning plate causes the ratchet to rotate accordingly. The ratchet further drives the transmission gear inside the main transmission device to rotate through the main transmission shaft. When torque overload occurs between the planetary gearbox and the transmission device, the positioning plate retracts backward with the help of the oblique meshing teeth on the surface of the ratchet and compresses the spring, so that the ratchet slips on the surface of the positioning plate, causing the planetary gearbox to idle inside, thereby protecting the transmission device from damage. Once the torque between the planetary gearbox and the main transmission box returns to a normal level, the second spring pushes the pressure plate under its own elastic action, and the pressure plate then pushes the positioning plate to re-engage with the ratchet, restoring the transmission connection between the planetary gearbox and the main transmission device, and realizing the automatic reset function. In addition, by rotating the adjusting bolt, the adjusting bolt can drive the telescopic shell to move, and when the telescopic shell moves, it drives the adjusting plate to move, and the adjusting plate squeezes the second spring, thereby adjusting the pressure applied by the second spring to the positioning plate, thereby changing the maximum torque value that can be tolerated between the positioning plate and the ratchet, significantly improving the torque adjustment performance and adjustability of the device.

[0018] (2) When the device is in use, the transmission gear rotates to cause the lubricating oil inside the main transmission device to splash, so that the lubricating oil can evenly lubricate the various gears inside the main transmission device. Under the action of the oil pump, the lubricating oil inside the main transmission device can enter the oil storage tank through the connecting groove, and then under the action of the magnetic rod inside the oil storage tank, the metal debris of the internal gear wear in the lubricating oil can be adsorbed and precipitated on the surface of the magnetic rod, which is beneficial to the effect of purifying the lubricating oil inside the main transmission device. The purified lubricating oil is filtered for the second time through the filter net, and then under the action of the oil pump, it re-enters the main transmission device through the circulation pipe to lubricate the gears. During the circulation of the lubricating oil inside the circulation pipe, the heat can be dissipated through the fins outside the circulation pipe, and then the air inside the guide pipe can be circulated quickly through the fan to drive the heat on the surface of the fin, so that the lubricating oil can be cooled during the circulation process, further improving the reliability of the device when in use.

[0019] (3) When the main transmission device drives the external device to rotate through the connecting shaft and the output shaft, when the torque between the connecting shaft and the output shaft is overloaded, the raised structure on the surface of the lower chuck will move out of the groove at the bottom of the upper chuck, and at the same time, the upper chuck will compress the first spring on the top, so that the lower chuck is in an idling state, which is beneficial to protecting the main transmission device. When the torque between the connecting shaft and the output shaft returns to normal, the upper chuck will be engaged with the lower chuck under the push of the first spring, so that the connecting shaft can drive the output shaft to output power, further improving the reliability of the device.
