Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, specifically relating to a worm gear reducer. Background Technology

[0002] Speed ​​reducers are found in the transmission systems of various machines, from transportation vehicles such as ships, automobiles, and locomotives, to heavy construction machinery, processing tools and automated production equipment used in the machinery industry, and even everyday household appliances and clocks. Their applications range from high-power transmission to low-load, precise angle transmission. In industrial applications, speed reducers have the function of both reducing speed and increasing torque. Therefore, they are widely used in speed and torque conversion equipment. A worm gear reducer is a power transmission mechanism that uses a gear speed converter to reduce the rotational speed of a motor to the desired speed and obtain a larger torque. Currently, speed reducers have a very wide range of applications in mechanisms used to transmit power and motion.

[0003] However, when worm gears drive each other, friction causes wear on the worm gears, which can reduce the transmission efficiency of the reducer and shorten its service life. Summary of the Invention

[0020] Preferred embodiment.

[0021] This embodiment provides a worm gear reducer, including a first housing 100. The first housing 100 contains a first worm gear 120 and a first worm 130. The first worm 130 is located at the lower end of the first housing 100, and the first worm gear 120 is located at the upper end of the first housing 100. The first worm gear 120 meshes with the first worm 130. The upper end of the first housing 100 has a first oil inlet 110 that matches the first worm gear 120. The upper end of the first housing 100 has a second housing 200, and the lower end of the second housing 200 has a first discharge port 210 that matches the first worm gear 120. The second housing 200 contains the first oil replenishment mechanism.

[0022] Furthermore, the first oil replenishment mechanism includes a first fixed block 230 and a first rotating block 220. The first fixed block 230 is disposed at the lower end of the second housing 200 and has a first through hole 231. The first rotating block 220 is disposed at the upper end of the first fixed block 230 and has a second through hole 221. The first through hole 231 matches the second through hole 221.

[0023] Furthermore, the first oil replenishment mechanism includes a first motor 250, a first sleeve 260 is provided at the upper end of the second housing 200, a first rotating rod 240 is provided at the upper end of the first rotating block 220, the first rotating rod 240 is matched with the first sleeve 260, a first gear 241 is provided at the upper end of the first sleeve 260, the first motor 250 is disposed at the upper end of the second housing 200, a second gear 251 is provided at the upper end of the first motor 250, and the first gear 241 is matched with the second gear 251.

[0024] Furthermore, the upper end of the second housing 200 is provided with a first oil filling port 270, the upper end of the first oil filling port 270 is provided with a first inlet 271, the lower end of the first oil filling port 270 is provided with a first retaining ring, and a first stop block 280 and a first spring 283 are provided between the first stop ring and the first inlet 271. The first stop block 280 matches the first inlet 271, and the first spring 283 is disposed between the first stop block 280 and the first retaining ring.

[0025] Furthermore, the lower end of the first stop block 280 is provided with a second sleeve 281, which matches the first oil filling port 270. The upper end of the second sleeve 281 is provided with a plurality of third through holes 282, and the upper end of the first spring 283 is sleeved inside the second sleeve 281.

[0026] Working principle: First, the first worm gear 130 is driven to rotate. Through the meshing of the first worm gear 130 and the first worm wheel 120, the first worm wheel 120 is driven to rotate, thus ensuring the operation of the reducer. The first motor 250 drives the second gear 251 to rotate. Through the cooperation of the first gear 241 and the second gear 251, the first gear 241 is driven to rotate, which in turn drives the first rotating rod 240 to rotate. Therefore, the first rotating block 220 rotates accordingly. During the rotation of the first rotating block 220, the first through hole 231 may connect with the second through hole 221. A small amount of lubricating oil inside the second housing 200 will then be exposed and fall onto the first worm wheel 120 through the first discharge port 210, thus ensuring the lubrication of the first worm wheel 120 and the first worm gear 130, thereby ensuring the efficiency and service life of the reducer. The second gear, with its smaller gear driving the larger gear, slows down the connection cycle between the first and second through holes, preventing lubricating oil from dripping into the first housing too quickly. Furthermore, lubricating oil can be added to the second housing 200 through the first oil filling port 270. The first spring 283 can lift the first stop block 280, which can block the first pouring port 271 to prevent lubricating oil from spilling out of the second housing 200. When adding lubricating oil to the second housing 200, the lubricating oil can push open the first stop block 280, enter the first sleeve 260 through the third through hole 282, and fall downward through the first retaining ring, which can ensure the amount of lubricating oil stored in the second housing 200.

[0027] It is worth mentioning that the technical features such as the first motor 250 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent.
