Description

Technical Field

[0001] This utility model belongs to the field of gear oiling technology, specifically relating to an automatic oiling device for open gears with dual oil passages. Background Technology

[0002] Gear meshing transmission is one of the main methods of mechanical transmission. Open gears are directly exposed to open working conditions and are easily corroded by external dust, water vapor, etc. Lubricating grease is the main way to maintain open gears. Traditional lubricating grease application is basically done manually, and the application effect is inconsistent and varies from person to person, making it impossible to achieve standardized lubrication. In addition, the equipment needs to be stopped when applying lubricating grease, which reduces the efficiency of equipment use and increases labor costs. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned technologies by providing a dual-oil-channel open gear automatic oil distribution device suitable for heavy-load, low-speed, large open gears.

[0004] To achieve the above objectives, this utility model provides a dual-oil-channel open gear automatic oil distribution device, including a base and an oil distribution component. A sliding platform is connected to the base via a sliding component. A telescopic component is provided on the base, connecting to the sliding platform and capable of moving the platform back and forth. The oil distribution component includes an oil distribution block, a shaft, and a reset component. The oil distribution block is integrally gear-shaped, comprising a cast rectangular portion and a gear-shaped portion. A cylindrical through hole is formed in the rectangular portion, and the shaft surface is fitted to fit the cylindrical through hole. The oil distribution block is rotatable relative to the shaft. Two sealing rings are provided on the shaft. Two sealing rings are located on the upper and lower sides of the oil distribution block, respectively. The sealing rings can prevent lubricating oil from overflowing and can limit the position of the oil distribution block. A through hole is provided on the sliding platform, and the inner wall of the through hole is fixedly connected to the side of the shaft. Two arc-shaped oil passages are opened in the cylindrical through hole, and two straight oil passages are opened inside the gear tooth part. The two straight oil passages are respectively connected to the two arc-shaped oil passages. The oil replenishment port of the two straight oil passages is located on both sides of the gear tooth part. An oil injection channel is provided inside the shaft, and the oil outlet of the oil injection channel is located at the center point of the distance between the adjacent two arc-shaped oil passages. The reset member is used to return the oil distribution block to its original position.

[0005] Preferably, the base is gate-shaped, the telescopic component is located on the horizontal column of the base, and sliding components are provided on both vertical columns of the base.

[0006] Preferably, the sliding component includes a slide rail and a slider sleeved on the slide rail. The slider can move relative to the slide rail. The slide rail is fixedly connected to the base, and the slider is fixedly connected to the sliding platform.

[0007] Preferably, the telescopic component is a push rod, which drives the sliding platform to move.

[0008] Preferably, the bottom surface of the shaft and the bottom surface of the sliding platform are on the same horizontal plane.

[0009] Preferably, the oil inlet of the oil injection channel is located on the bottom surface of the shaft body, which facilitates the installation of the external oil injection pipe.

[0010] Preferably, the number of reset components is at least two.

[0011] Preferably, the reset component is a return spring, with one end of the return spring fixedly connected to the sliding platform and the other end of the return spring fixedly connected to the rear side of the cuboid portion.

[0012] Preferably, the base is provided with mounting holes.

[0013] Preferably, the number of mounting holes is at least two.

[0014] The beneficial effects of this utility model are as follows: 1. First, the base is fixedly installed on one side of the open gear to be oiled. The external oil supply pipe is connected to the oil inlet of the oil injection channel. The sliding platform is pushed towards the open gear through the telescopic component, so that the gear teeth of the oiling block enter the tooth groove of the open gear. When the open gear rotates, it will drive the oiling block to rotate around the shaft at a certain angle. During the rotation, the oil outlet of the oil injection channel will connect with one of the arc-shaped oil channels. At this time, the grease in the oil injection channel first enters the arc-shaped oil channel, then enters the straight oil channel inside the gear teeth, and finally is discharged to the surface of the open gear through the oil replenishment port on the gear teeth. The two arc-shaped oil channels can be matched with the rotation direction of the open gear to increase the applicable range. The two return springs can make the oiling block automatically reset, so as to replenish the oil to multiple gear teeth of the open gear in sequence. In the natural state, the oil outlet of the oil injection channel is offset from the arc-shaped oil channel, so no oil will come out.

[0015] 2. The grease is discharged sequentially through the oil injection channel, the arc-shaped oil channel, and the straight oil channel, which achieves uniform application of grease to the surface of the open gear to be lubricated. The method of applying grease while the open gear is running eliminates downtime, increases the effective working time of the equipment, solves the problem of poor results when applying grease manually in the traditional way, and also reduces labor costs and safety hazards.
