Abstract
Description
Technical Field
[0001] The utility model relates to the field of transmission devices, in particular to a reduction shaft transmission device. Background Art
[0002] A reduction shaft transmission is a mechanical device used to transmit power while simultaneously reducing speed. It primarily consists of a reduction shaft, gears, and bearings. Through the meshing of the gears and the rotation of the drive shaft, it converts high-speed, low-torque input power into low-speed, high-torque output power. As the core component of the transmission, the reduction shaft receives and transmits the input power, while the gears reduce the speed, resulting in a lower output speed and higher torque. Gears are mounted on the reduction shaft or on a mating shaft, meshing with each other to achieve both power transmission and reduction. The gear ratio determines the reduction ratio—the ratio of output speed to input speed. Bearings support the reduction shaft and other rotating components, reducing friction and wear and ensuring smooth operation of the transmission. The operating principle of a reduction shaft transmission is based on the principle of gear transmission. When the input shaft rotates the driving gear, it meshes with the driven gear (mounted on the reduction shaft), driving the reduction shaft. Because the number of teeth on the driving and driven gears differs, the speed of the reduction shaft decreases while the torque increases. This reduction and torque increase is achieved through the gear ratio. During the operation of the reduction shaft transmission device, the internal gears will engage, and in this process, collision and friction will occur between the gears, thereby generating metal debris. If the metal debris is not collected in time, the metal debris will easily adhere to the gears repeatedly. As the gears continue to engage, the metal debris attached to the gears will aggravate the wear of the gears, and ultimately make the transmission device prone to damage, increase the cost of using the transmission device, and reduce the service life of the transmission device. Therefore, a reduction shaft transmission device is needed to solve the above problems. Utility Model Content

The metal debris collection assembly 2 consists of an arc-shaped sealing plate 5, a mounting plate 6, an arc-shaped plug plate 7, an arc-shaped collection box 8, a partition baffle 9, an adsorption magnet 10 and a porous sponge pad 11. There are two mounting plates 6 and they are fixedly mounted on both ends of the arc-shaped sealing plate 5, the arc-shaped plug plate 7 is fixedly mounted on the inner end of the arc-shaped sealing plate 5, the arc-shaped collection box 8 is fixedly mounted on the inner end of the arc-shaped plug plate 7, there are two partition baffles 9 and they are symmetrically fixed in the arc-shaped collection box 8, and there are four adsorption magnets 10 and they are fixedly mounted on the two At both ends of the partition baffle 9, there are three porous sponge pads 11 and they are all fixedly installed in the arc-shaped collection box 8. The upper end of the reducer lower shell 1 is fixedly installed with the reducer upper shell 3. The reducer lower shell 1 and the reducer upper shell 3 are installed with a reduction shaft transmission component 4. Two through slots for inserting the metal debris collection component 2 are symmetrically opened on the two side walls of the reducer lower shell 1. During use, when the reduction shaft transmission component 4 is driven, the gears on the reduction shaft transmission component 4 will produce meshing friction. At this time, the metal debris generated by the gear meshing will be thrown into the arc-shaped collection box 8 on the metal debris collection component 2 as the gears rotate. When the metal debris enters the arc-shaped collection box After the metal debris is put into the arc collecting box 8, some of the metal debris will fall into the holes on the porous sponge pad 11, and some of the metal debris will be attracted by the adsorption magnet 10. Then, the presence of the porous sponge pad 11 and the adsorption magnet 10 can reduce the probability of the metal debris escaping from the arc collecting box 8. When it is necessary to clean the metal debris in the arc collecting box 8, the oil in the reducer lower shell 1 and the reducer upper shell 3 can be drained first, and then the bolts for fixing the fixing plate 6 can be removed, and then the metal debris collecting assembly 2 can be pulled out from the reducer lower shell 1, and then the metal debris on the porous sponge pad 11 and the adsorption magnet 10 can be cleaned, and finally the metal debris can be cleaned by setting the metal The debris collection component 2 can collect metal debris generated by the gear meshing friction on the reduction shaft transmission component 4, thereby reducing the probability of metal debris repeatedly adhering to the gears, thereby reducing gear wear, and ultimately making the reduction shaft transmission component 4 less likely to be damaged, reducing the use cost of the transmission device, and improving the service life of the transmission device. At the same time, the metal debris collection component 2 is inserted from the outside to the inside under the reduction shaft transmission component 4, and the metal debris collection component 2 can be disassembled and cleaned without disassembling the reducer lower shell 1 and the reducer upper shell 3, thereby making the disassembly and cleaning of the metal debris collection component 2 more convenient and quick.
[0020] Furthermore, the two metal debris collection components 2 are both located below the reduction shaft transmission component 4. The arc-shaped sealing plate 5 and the mounting fixing plate 6 on the metal debris collection component 2 are both located on the outside of the reducer lower housing 1. The mounting fixing plate 6 is provided with a mounting fixing hole 12, and the mounting fixing plate 6 is fixedly connected to the reducer lower housing 1 by bolts.

The space inside the box 8 is divided into three parts, and three porous sponge pads 11 are respectively fixedly installed in the three spaces divided by the two partition baffles 9. Smaller metal debris that falls into the arc-shaped collection box 8 will fall into the holes on the porous sponge pad 11 due to gravity, while the larger metal debris that cannot enter the holes on the porous sponge pad 11 will roll along the porous sponge pad 11. Finally, the larger metal debris will be adsorbed by the adsorption magnet 10, so that the metal debris that enters the arc-shaped collection box 8 can be fixed by the porous sponge pad 11 and the adsorption magnet 10.
