Description

Technical Field

[0001] The utility model relates to the technical field of gear sets, in particular to a gear set with a self-lubricating structure. Background Art

[0002] A gear set is a system composed of multiple gears, which is mainly used to transmit torque, change speed and torque direction. It is widely used in metallurgical equipment, transmission boxes and other fields. The design principle of a gear set usually requires that the common divisor of the number of teeth of adjacent gears is as small as possible to ensure uniform wear of the gears and long-term stable operation. The gear set needs lubrication during use to maintain its normal operation. Poor lubrication may cause damage to the gear set.

[0003] The patent with publication number CN220452672U discloses an automatic lubrication structure of a gear set, wherein a groove is provided on the side of the secondary gear, and the sealing cover is buckled on the outer side of the secondary gear and welded and fixed thereto, and the interior of the sealing cover is a hollow structure, and a knocking rod is fitted on the side of the sealing cover, and a movable shaft is provided on the knocking rod, and the knocking rod is rotatably connected to the sealing cover through the movable shaft, and the connecting part is provided at one end of the knocking rod, and the fixed tube is fixedly provided on the inner side of the sealing cover, and the interior of the fixed tube is a hollow structure and fixed integrally with the sealing cover; the secondary gear drives the knocking rod to rotate synchronously, and the knocking rod collides with the protrusion on the main gear when rotating, and the protrusion moves one end of the knocking rod, and the knocking rod can be rotated by the movable shaft, and the end of the knocking rod away from the protrusion presses down the connecting part, so that the connecting part pushes the push rod downward to squeeze the lubricant inside the fixed tube, and the lubricant inside the sealing cover is compressed to open the cross groove and spray out, thereby realizing self-lubrication when the main gear and the secondary gear rotate.

[0004] During the specific use of the above-mentioned prior art, when the secondary gear rotates one circle, the knocking rod is moved at least once, and each time the knocking rod is moved, the connecting part is driven to move downward, so that the connecting part drives the push rod to squeeze the lubricant in the fixed tube. The gears of the gear set often rotate continuously when working, which causes the lubricant in the sealing cover to be consumed quickly, and the cross groove on the sealing gasket can be opened. There is a lack of a one-way valve in the injection pipe, which causes the outside air to enter the sealing cover from the cross groove when the push rod is reset, resulting in the intake valve not working. The lubricant in the sealing cover will also flow out due to the air intake at the cross groove, which accelerates the consumption rate of the lubricant and makes it difficult to play a long-term lubrication role. In view of this, we propose a gear set with a self-lubricating structure. Utility Model Content
