Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a speed reducer, particularly a speed reducer with circulating lubrication. Background Technology

[0002] A speed reducer is an independent component composed of gear transmission, worm gear transmission, or worm drive. It is commonly used as a speed reduction transmission device between the prime mover and the working machine, and plays a role in matching speed and transmitting torque between the prime mover and the working machine or actuator.

[0003] Traditional speed reducers use splash lubrication, relying on the rotation of gears to throw up lubricating oil. However, this method makes it difficult to ensure that the lubricating oil is evenly covered to all moving parts, especially under low-speed or heavy-load conditions, where the lubrication effect is even worse and can easily lead to severe local wear. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a speed reducer with both gear circulating lubrication and oil circulating functions.

[0005] The objective of this utility model can be achieved through the following technical solution: A speed reducer with circulating lubrication includes a speed reducer housing and a drive shaft installed inside the speed reducer housing, with one end of the drive shaft extending outside the speed reducer housing. The speed reducer housing contains a speed reduction device connected to the drive shaft. The speed reduction device is provided with a transmission seat and a transmission cover, and a cavity is formed between the transmission seat and the transmission cover. The drive shaft extends into the cavity and is equipped with a drive gear. The transmission seat has a plurality of transmission gears arranged in a triangular pattern, each transmission gear meshing with the drive gear. A fixed platform is provided between each transmission gear, and an oil circuit unit for lubricating the gears is provided within the fixed platform.

[0006] In the aforementioned type of reducer with circulating lubrication, the oil circuit unit has an oil storage chamber with an inverted conical structure. An oil inlet pipe for adding oil to the oil storage chamber is located at the top of the oil storage chamber within a fixed platform, and a sealing bolt for sealing the oil inlet pipe is provided at the port of the oil inlet pipe. Inclined oil outlet pipes are located on both sides of the oil storage chamber within the fixed platform, and the oil outlet pipes are symmetrical. An oil nozzle communicating with the oil outlet pipe is provided on the fixed platform.

[0007] In the aforementioned type of speed reducer with circulating lubrication, a plurality of gear grooves are evenly provided on the inner wall of the speed reducer housing, and each of the transmission gears is tightly meshed with the gear groove.

[0008] In the aforementioned type of reducer with circulating lubrication, the fixed platform is distributed in a triangular structure on the transmission seat, and the fixed platform and the transmission seat are designed as an integral unit. The transmission seat and the transmission cover are connected by bolts.

[0009] In the aforementioned type of reducer with circulating lubrication, the oil circuit unit has a triangular structure design.

[0010] Working principle: When the reducer is running, the drive shaft drives the drive gear to rotate, which in turn drives the other transmission gears. Lubricating oil in the oil reservoir flows out through symmetrically inclined oil outlet pipes on both sides under gravity, and is sprayed onto the gear surface through oil nozzles to lubricate the gears. The sprayed lubricating oil, driven by the gears, drips along the teeth onto the fixed platform, and then enters the oil reservoir through the oil nozzles. Lubricating oil dripping onto the inner wall of the reducer housing adheres to the transmission gears during rotation, and is then dripped back onto the fixed platform by the rotation of the transmission gears. During rotation, the fixed platform rotates with the transmission base, allowing the lubricating oil to re-enter the oil circuit unit for reuse.

[0011] Compared with existing technologies, this reducer with circulating lubrication, through the precise design of the oil circuit unit, can evenly spray lubricating oil onto the gear surface to form a stable oil film, effectively reducing friction and wear between gears and improving the transmission efficiency of the reducer; after lubricating the gears, the lubricating oil will flow back into the oil circuit unit for recycling, reducing lubricating oil consumption and cost.
