Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, in particular to a planetary speed reducer convenient for lubrication. Background Art

[0002] The planetary speed reducer is a widely used industrial product, which belongs to a kind of power transmission device and is especially suitable for occasions where it is necessary to reduce the motor speed and increase the output torque. The working characteristics of the joint part of the planetary speed reducer are frequent starting and reciprocating motion in a small space. This working mode is easy to cause wear of internal parts. The lubricant can form an oil film between the contact surfaces of the parts, reducing the direct contact between the parts.

[0003] After retrieval, the Chinese patent with the publication number CN219082181U discloses a planetary gear of a speed reducer convenient for dripping lubrication. When lubricating the existing planetary gear, it is necessary to stop the planetary gear, and then the master disassembles the gears one by one, drips oil for lubrication, and finally reassembles them. This method is time-consuming and laborious, affecting the use of the planetary gear. Therefore, not only can it lubricate the planetary gear during its working state through the cooperation of the rubber oil bag and the top block, reducing the lubrication time after disassembly, but also it can conveniently control the rotation speed of the output shaft on the planet carrier through the cooperation of the sun gear and the pinion, improving the practicability of the planetary gear. It can also control the flow rate of the rubber oil bag by rotating the top block to make the screw contract or extend.

[0004] When lubricating the planetary speed reducer above, an oil outlet pipe is used to drip oil on the internal gear components of the speed reducer. The internal gear ring parts of the speed reducer are usually annular. If only one pipeline is used to add and apply oil to the lubricating oil, it is easy to cause the lubricating oil applied to the internal gear ring of the speed reducer to be relatively uneven, easily generating an oil application dead angle, thereby reducing the oil application quality. And it is not convenient to brush the oil application surface of the gear ring after oil application, easily causing the lubricating oil to accumulate, resulting in the accumulation of lubricating oil on one side of the gear ring while the other side does not contact the lubricating oil, thus causing waste of the lubricating oil.

The folding tube 4 is convenient for adapting to the rotation of the oil storage ring 5, the sponge pad 6 is convenient for absorbing lubricating oil, and the brush hairs 8 are convenient for applying lubricating oil.

[0035] As shown in the attached Figure 3 figure, an oil receiving component is arranged inside the reducer body 1, and the oil receiving component includes a guiding ring 15, the guiding ring 15 is fixedly connected inside the reducer body 1, and the guiding ring 15 is convenient for guiding the dripping lubricating oil.

[0036] As shown in the attached Figure 5 figure, a sealing ring 16 is arranged on the lower surface of the reducer body 1, which is convenient for connecting with a sealing ring 24.

[0037] As shown in the attached Figure 1 figure, an oil receiving shell 17 is fixedly connected to the lower surface of the reducer body 1, fixing blocks 18 are fixedly connected to both sides of the oil receiving shell 17, installation boxes 19 are fixedly connected to both sides of the reducer body 1, a bolt 20 is threadedly connected to one side of the installation box 19, and a liquid blocking cover 10 is threadedly connected to the other end of the folding tube 4. The oil receiving shell 17 is convenient for collecting lubricating oil, and the bolt 20 is convenient for fixing the oil receiving shell 17 below the reducer body 1 under the action of the fixing block 18.

[0038] As shown in the attached Figure 6As shown, two oil drain pipes 21 are fixedly connected to the lower surface of the oil receiving shell 17, and one end of the oil drain pipe 21 is threadedly connected to a threaded cover 22 to facilitate the discharge of the lubricating oil.

[0040] Working principle: when applying lubricating oil to the reducer body 1, first unscrew the liquid blocking cover 10, and then pour the lubricating oil into the inside of the folding tube 4. At this time, the lubricating oil will flow along the folding tube 4 to the inside of the oil storage ring 5 and be absorbed by the sponge pad 6. Then tighten the liquid blocking cover 10 and open the hydraulic cylinder 13, so that the output end of the hydraulic cylinder 13 drives the rack 14 to reciprocate, and the meshing of the rack 14 and the driving gear 12 facilitates the driving gear 12 to reciprocate, and the meshing of the driving gear 12 and the outer gear ring 9 facilitates the driving gear 12 to drive the outer gear ring 9 to reciprocate, and the outer gear ring 9 will drive the oil storage ring 5 to rotate synchronously.

When the reducer is working, under the meshing connection between the internal gears of the reducer and the inner gear ring 3, it is convenient to adhere the lubricating oil on the inner gear ring 3 to the gear parts, so as to facilitate the indirect application of lubricating oil to the gears, thereby improving the quality of the lubricating oil applied to the internal parts of the reducer body 1;

[0041] When the lubricating oil is excessively applied and drips, the guide ring 15 can guide the lubricating oil to the arc groove at the bottom of the reducer body 1, and then flow to the filter plate 23 to be filtered by the filter plate 23, so that impurities in the lubricating oil are retained, and the lubricating oil flows into the oil receiving shell 17 after passing through the filter plate 23 and is collected, and then the collected lubricating oil is discharged by the oil drain pipe 21. When it is necessary to remove the collecting assembly from the reducer body 1, the bolt 20 is tightened to facilitate the bolt 20 to detach from the inside of the fixing block 18, and then the fixing block 18 is pulled out of the inside of the mounting box 19, so as to facilitate the removal of the collecting assembly and help clean the filter plate 23.
