Description
Technical Field
[0001] The utility model relates to the technical field of reducer equipment, in particular to a reducer. Background Art
[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is mainly used as a reduction transmission device between the prime mover and the working machine or actuator to match the speed and transmit torque. In modern machinery, reducers are widely used. The core function of a reducer is to reduce the speed of an electric motor, internal combustion engine, or other high-speed power source through its internal gear system, while increasing the output torque. This process is achieved through the meshing of a gear with fewer teeth on the input shaft and a large gear on the output shaft. Ordinary reducers usually contain several pairs of gears with the same principle to achieve an ideal reduction effect. The ratio of the number of teeth of these gears is called the transmission ratio, which determines the reduction effect and output torque of the reducer.
[0003] The application fields of reducers are very wide, including but not limited to industrial production, household appliances, medical equipment, military equipment, transportation and new energy fields. In industrial production, reducers are widely used in various production machinery, such as conveyors, papermaking machines, smelting equipment, etc. In the field of household appliances, mixers, food processors, washing machines, etc. also often use reducers. In addition, reducers also play an important role in new energy fields such as wind turbines and solar power generation equipment.
[0004] However, the reducer will generate vibration to a certain extent during operation. The existing reducer lacks an effective shock-absorbing component. The existing shock-absorbing component cannot guarantee its stability when playing a shock-absorbing role, so it may cause left and right shaking, affecting the sealing effect of the reducer. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a reducer to solve the problem that the reducer will generate vibration to a certain extent during operation, and the existing reducer lacks an effective shock-absorbing component. The existing shock-absorbing component cannot guarantee its stability when playing a shock-absorbing role, so it may cause left and right shaking, affecting the sealing effect of the reducer.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reducer, comprising a reducer body, a fixed bottom plate is arranged at the bottom of the reducer body, connecting rods are rotatably connected on both sides of the bottom of the fixed bottom plate in a symmetrical structure, a fixed base is arranged at the bottom of the fixed base plate, a fixed block is fixedly installed on the top of the fixed base in a symmetrical structure, a sliding rod is arranged between the fixed blocks, the bottom of the connecting rod movably passes through the sliding rod, a first spring is arranged on the outside of the sliding rod, the first spring is fixed between the connecting rods, a plurality of groups of air guide cylinders are fixedly installed in the fixed base, a first movable block is arranged in the air guide cylinder, a top rod is fixedly connected to the top of the first movable block, a second spring is arranged between the air guide cylinder and the fixed bottom plate, the top rod is located at the bottom of the fixed bottom plate, an air pipe is fixedly installed between the air guide cylinders, a shock-absorbing cylinder is arranged between the air pipes, a second movable block is arranged in the shock-absorbing cylinder, a movable rod is fixedly installed on the top of the second movable block, a top block is fixedly connected to the top of the movable rod, and the top block is made of rubber material.

When the gas in the gas cylinder is squeezed, it will move toward the gas pipe, and the gas enters the shock-absorbing cylinder through the gas pipe, and then squeezes the second movable block, so that the second movable block and the movable rod can move upward at the same time, so that the top block can squeeze the bottom of the fixed bottom plate. When the fixed bottom plate vibrates and moves downward, the mutual cooperation between the gas pipe, the gas pipe and the shock-absorbing cylinder can achieve the effect of supporting and limiting the fixed bottom plate, which is similar to the above technical solution. At the same time, through the cooperation between the connecting rod and the sliding rod and between the sliding rods, the buffering and shock-absorbing effect of the reducer can be achieved, and the reducer can be prevented from shaking and vibrating on the fixed base plate. When the top block is made of rubber material, it can better contact with the fixed base plate to achieve the supporting effect, and can also cooperate with the shock-absorbing cylinder to assist in the shock-absorbing and buffering effect, so as to solve the problem that the reducer will vibrate to a certain extent during operation. The existing reducer lacks an effective shock-absorbing component. The existing shock-absorbing component cannot guarantee its stability when playing a shock-absorbing role, so it may shake left and right, affecting the sealing effect of the reducer.

[0015] By adopting the above technical solution, the provided installation groove and the opening groove cooperate with each other so that the transmission mechanism can move flexibly in the reducer body.
[0016] In summary, the utility model mainly has the following beneficial effects:
[0017] The utility model compresses the top rod when the fixed bottom plate vibrates, thereby pushing the first movable block downward to compress the gas in the gas guide cylinder. When the gas in the gas guide cylinder is squeezed, it moves toward the gas pipe, and the gas enters the shock-absorbing cylinder through the gas pipe, and then compresses the second movable block, so that the second movable block and the movable rod can move upward at the same time, so that the top block can compress the bottom of the fixed bottom plate. When the fixed bottom plate vibrates and moves downward, the mutual cooperation between the gas pipe, the gas pipe and the shock-absorbing cylinder can achieve the effect of supporting and limiting the fixed bottom plate. At the same time, Through the cooperation between the connecting rod and the sliding rod and between the sliding rods, the buffering and shock-absorbing effect of the reducer can be achieved, and the reducer can be prevented from shaking and vibrating on the fixed base plate. When the top block is made of rubber material, it can better contact with the fixed base plate to achieve the supporting effect, and can also cooperate with the shock-absorbing cylinder to assist in the shock-absorbing and buffering effect, so as to solve the problem that the reducer will vibrate to a certain extent during operation.

[0028] During use, when the fixed bottom plate 6 vibrates, the top rod is squeezed, so that the first movable block 20 is pushed downward to squeeze the gas in the gas cylinder 19. When the gas in the gas cylinder 19 is squeezed, it moves toward the gas pipe 17, and the gas enters the shock-absorbing cylinder 18 through the gas pipe 17, and then squeezes the second movable block 23, so that the second movable block 23 and the movable rod 21 can move upward at the same time, so that the top block 22 can squeeze the bottom of the fixed bottom plate 6.
