Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a light gear reducer. Background Art

[0002] Commonly used reducers include ordinary cylindrical gear reducers, worm gear reducers and planetary gear reducers, etc. The traditional cylindrical gear reducer uses a gear speed converter to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. Gear reducers are generally used for low-speed and high-torque transmission equipment. Ordinary reducers for electric motors will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio. With the continuous development of the reducer industry, more and more companies are using reducers. The R series coaxial helical gear reducer is manufactured in accordance with international technical requirements. It has high technological content, saves space, is reliable and durable, has high overload capacity, can reach a power of 132KW, has low energy consumption, and has superior performance. The reducer efficiency is as high as 95%, with low vibration, low noise, and high energy saving. It uses high-quality forged steel materials and a rigid cast iron housing. The gear surface is subjected to high-frequency heat treatment and precision machining to ensure the parallelism of the shaft and the positioning bearing requirements. The reducer that forms the helical gear transmission assembly is equipped with various types of motors and combined into a mechatronics, which fully guarantees the product's quality characteristics. The gear reducer uses various levels of gear transmission to achieve the purpose of speed reduction. The reducer is composed of gear pairs at various levels. For example, using a small gear to drive a large gear can achieve a certain purpose of speed reduction. If a multi-level structure is used, the speed can be greatly reduced.

[0003] Since the gear reducer needs to have its internal gears maintained after working for a long time, currently, the gears are maintained by removing the outer casing of the gear reducer and applying lubricating oil to the surface of the gears. This method is not only time-consuming and labor-intensive, but also easily causes misalignment of the gears during reassembly, thereby preventing the gear reducer from working properly. Therefore, we propose a method that can drip lubricating oil on the gears when the gear reducer is working to maintain the gears, that is, a light gear reducer. Utility Model Content

[0023] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Commonly used reducers include ordinary cylindrical gear reducers, worm gear reducers and planetary gear reducers, etc. The traditional cylindrical gear reducer uses a gear speed converter to reduce the motor's rotation speed to the required rotation speed and obtain a larger torque. Figure 1-Figure 6As shown, the utility model provides a light gear reducer, including a shell 1, a bottom rear end of the shell 1 is rotatably connected to a plurality of reduction gear assemblies 13, a bottom front end of the shell 1 is rotatably connected to a rotating shaft 11, a gear 12 is fixedly connected to the left side of the rotating shaft 11, a cam 2 is fixedly connected to the right side of the rotating shaft 11, a push plate 21 is placed at the rear end of the cam 2, the push plate 21 is slidably connected to the bottom and top of the shell 1, a push rod 22 is fixedly connected to the top of the push plate 21, a push block 23 is fixedly connected to the other end of the push rod 22, the push block 23 is slidably connected to the front end of an oil storage tank 3, the oil storage tank 3 is slidably connected to the top of the shell 1, and a plurality of oil dripping pipes 31 are fixedly connected to the bottom of the oil storage tank 3.

[0025] The improvement of the utility model is:

[0026] Since the gear reducer needs to be maintained after working for a long time, the gears are currently maintained by removing the housing 1 of the gear reducer and applying lubricating oil to the surface of the gears. This method is not only time-consuming and labor-intensive, but also easily causes misalignment of the gears during reassembly, thereby causing the gear reducer to not work properly. Therefore, when the gear reducer is working, the gear 12 rotates, driving the rotating shaft 11 to rotate, thereby driving the cam 2 to rotate. When the cam 2 rotates, it pushes the push plate 21 to move backward, and the push plate 21 pushes the push block 2 through the push rod 22. 3. The push block 23 slides inward at the front end of the oil storage tank 3, thereby increasing the pressure inside the oil storage tank 3, squeezing the lubricating oil inside the oil storage tank 3, allowing it to drip out from the oil dripping pipe 31 at the bottom of the oil storage tank 3 and fall onto the reduction gear assembly 13 below, thereby lubricating and maintaining the reduction gear assembly 13. After the push block 23 slides for a distance, the push plate 21 contacts the front end of the oil storage tank 3, thereby continuing to push the oil storage tank 3 to move backward, and at the same time driving the oil dripping pipe 31 to move forward and backward, increasing the oil dripping area, thereby ensuring that the reduction gear assembly 13 can be fully lubricated.

[0027] Taking into account the longitudinal stability and lateral sliding of the oil storage tank 3 on the top of the shell 1, a slide plate 32 is fixedly connected to the left and right sides of the oil storage tank 3. The slide plate 32 is a "T"-shaped structure. A slide groove 15 is provided on the top inner surface of the shell 1. The size of the slide groove 15 corresponds to the slide plate 32. The slide plate 32 cooperates with the slide groove 15 to ensure that the oil storage tank 3 can slide back and forth on the top of the shell 1.

[0028] In order to ensure that after the cam 2 pushes the push plate 21, the push plate 21 can automatically return to its initial position, thereby performing a forward and backward cyclic movement, a groove 14 is provided at the front end of the bottom of the shell 1, and a spring 25 is fixedly connected to the inner surface of the groove 14, and the other end of the spring 25 is fixedly connected to the bottom of the push plate 21. A spring 233 is fixedly connected to the rear end of the top of the shell 1, and the other end of the spring 233 is fixedly connected to the rear end of the oil storage tank 3. When the cam 2 pushes the push plate 21, the spring 25 is compressed. When the cam 2 moves away from the push plate 21, the push plate 21 returns to its initial position under the action of the elastic force of the spring 25. Similarly, the oil storage tank 3 returns to its initial position under the action of the elastic force of the spring 233.

[0029] Taking into account that when the light gear reducer is not working, lubricating oil will drip from the oil dripping pipe 31, causing unnecessary waste, therefore, a plurality of oil outlet pipes 34 are fixedly connected to the bottom of the oil dripping pipe 31, and a spring three 35 is sleeved on the outer surface of the oil outlet pipe 34, one end of the spring three 35 is fixedly connected to the bottom of the oil dripping pipe 31, and the other end of the spring three 35 is fixedly connected to the baffle 36. When the lubricating oil is squeezed out of the oil outlet pipe 34, the spring three 35 is stretched. When the pressure in the oil storage tank 3 is reduced, under the action of the elastic force of the spring three 35, the spring three 35 drives the baffle 36 to block the oil outlet pipe 34, thereby avoiding waste of resources.

[0030] Since the dripping of lubricating oil is achieved by increasing the pressure inside the oil storage tank 3, the oil storage tank 3 should have good sealing performance. Therefore, the outer surface of the push block 23 is fixedly connected with a rubber pad 24, and the rubber pad 24 is tightly fitted with the front end inner surface of the oil storage tank 3. The rubber pad 24 has good sealing performance, thereby ensuring that when the push block 23 slides at the front end of the oil storage tank 3, the pressure inside the oil storage tank 3 can be better increased.

[0031] Taking into account that the oil storage tank 3 can be replenished in time when the lubricating oil is used up, a filling pipe 37 is fixedly connected to the top of the oil storage tank 3, and a cover 38 is slidably provided on the top of the filling pipe 37. It is very convenient to add the lubricating oil directly from the filling pipe 37. After refueling, the cover 38 is covered to ensure that the oil storage tank 3 is in a sealed state.

[0032] In summary, the working principle of this solution is as follows:

[0033] Before using the light gear reducer, add lubricating oil from the filling pipe 37 into the oil storage tank 3, cover the cover 38, and let the light gear reducer start working. The gear 12 rotates, driving the rotating shaft 11 to rotate, thereby driving the cam 2 to rotate. When the cam 2 rotates, it pushes the push plate 21 to move backward. The push plate 21 pushes the push block 23 through the push rod 22. The push block 23 slides inward at the front end of the oil storage tank 3, thereby increasing the pressure inside the oil storage tank 3, squeezing the lubricating oil inside the oil storage tank 3, and letting it drip out from the drip pipe 31 at the bottom of the oil storage tank 3 and fall to the reduction gear below. The push plate 21 contacts the front end of the oil storage tank 3 after the push block 23 slides for a certain distance, thereby continuing to push the oil storage tank 3 to move backward, and at the same time drives the oil dripping pipe 31 to move forward and backward, thereby increasing the oil dripping area, thereby ensuring that the reduction gear assembly 13 can be fully lubricated. When the lubricating oil is squeezed out from the oil outlet pipe 34, the spring three 35 is stretched. When the pressure in the oil storage tank 3 is reduced, under the action of the elastic force of the spring three 35, the spring three 35 drives the baffle 36 to block the oil outlet pipe 34, thereby avoiding waste of resources.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
