Excuse me, which type of reducer has a small size and a large reduction ratio.

This must be the cycloid, that is, the cycloidal pinwheel reducer.

Generally, the speed ratio of the first level can be 6 87, and the second level is 6533

The first-stage speed ratio of Sumitomo cycloid reducer in Japan can reach 6 119

The second stage has a speed ratio of 104 7569

I am the office of Sumitomo reducer, our cycloid reducer has a impact resistance of 500%, the number of parts is small, so the reliability is high, there is a factory in China, so it is lower than other brands as soon as possible (but the cycloidal wheel requires high precision grinding, high heat treatment process, so imported from Japan), small size, can be done servo motor, frequency conversion motor, with brake, with encoder, various voltages, various installation methods and other types to choose from, And half of our low-power and small-frame cycloid reducers are lubricated with maintenance-free grease, that is, before the reducer leaves the factory, we have added the lubricating grease, and the customer does not need to maintain the grease during use.

Moreover, we can provide customers with a variety of solutions, that is, we will help customers to provide customers with the most suitable reducer for different equipment, working conditions, requirements, etc.

You's**? I do the reducer and email me the parameter requirements.

1.Reducer.

The reduction ratio (also called the gear ratio.

It is the rated speed of your motor divided by the actual speed: 1.

2.Define the calculation method: reduction ratio = input speed and output speed; 2.

General calculation method: reduction ratio = 9550 motor power use torque, motor power input speed use coefficient, MB continuously variable transmission precautions; 3.Calculation method of gear train:

Reduction ratio = the number of driven gear teeth and the number of driving gear teeth (in multi-stage deceleration, multiply the number of driven gear teeth by the number of driving gear teeth of all meshing gear sets to obtain NRV reducer; 4.Calculation method of reduction ratio of belt, chain and friction wheel: reduction ratio = diameter of driven wheel, diameter of driving wheel, how to add lubricating oil to helical gear reducer and cycloidal pin wheel reducer.

The deceleration level of the reducer can be seen from the reduction ratio of the reducer. The reduction ratio is the ratio of the speed of the output shaft to the speed of the input shaft. For example, if the reduction ratio of the reducer is 50:

1, then the reduction ratio of the reducer is 50. In addition, the deceleration level of the reducer can also be seen from the model of the reducer. For example, if the reducer model is "50-1", the deceleration level of the reducer is 50.

The higher the deceleration level of the reducer, the stronger the deceleration capacity of the reducer. However, the size and weight or buried capacity of the reducer with high deceleration level are usually large, and it is necessary to consider the use of the occasion and space limitations.

Calculation method of reduction ratio of reducer:

1. Define the calculation method: reduction ratio = input speed output speed, the ratio of the connected input speed and output speed, such as the input speed is 1500r min and the output speed is 25r min, then the reduction ratio is: i = 60:1.

2. Calculation method of the number of gear teeth: reduction ratio = number of driven gear teeth and number of driving gear teeth (if it is a multi-stage gear reduction, then the number of driven gear teeth and the number of driving gear teeth of a pair of gear sets that are meshed together, and then multiply the results obtained.) For example, if z2=100 and z1=25, then i=100 25.

3. Calculation method of reduction ratio of belt, chain and friction wheel: reduction ratio = diameter of driven wheel and diameter of driving wheel.

1--- ratio.

The reduction ratio of the reducer is roughly the number of the rated speed of the motor divided by the final output speed. For example, the speed of the final output is 200rpm, and the rated speed of the motor is 3000rpm, so the speed ratio of the reducer is about 1:15.

The final output speed depends on the operating conditions.

2--- torque.

The rated torque of the reducer should be greater than or equal to the rated torque of the motor multiplied by the reduction ratio. Assuming that the rated torque of the motor is 15 and the reduction ratio is 15, then the rated torque of the selected reducer model should be greater than 10*15=.

3--- accuracy.

The return clearance (backlash, clearance or slewing clearance) of the reducer depends on the specific work requirements, generally speaking, the clearance used with the servo motor should not be greater than 20arcmin, and the single-stage deceleration can be less than or equal to 5arcmin is generally a high-end product.

4--- specifications.

The cross-sectional size of the reducer is generally about the same as the cross-sectional size of the motor.

It is best to refer to the description of the selected brand for other parameters, and the technical sample is generally marked with the selection steps and calculation examples. The specific model is indicated differently by brand. It is usually roughly expressed in terms of output flange size or cross-sectional size, and there are generally other specifications.

For example: Panasonic 400w with 60 box number planets, Panasonic 750w generally with 90 box number planets.

This is not easy to determine, you need to know the situation of your use of geared motors, the use of the environment. What kind of machine. For example, if you use it on a hoist, then you need to use a worm gear. If you are using a model with a relatively light load, you can consider it.

How to calculate the reduction ratio.

1. Define the calculation method: reduction ratio = input speed output speed, the ratio of the connected input speed and output speed, such as the input speed is 1500r min and the output speed is 25r min, then the reduction ratio is: i = 60:1.

2. Gear train calculation method: reduction ratio = number of driven gear teeth number of driving gear teeth (if it is a multi-stage gear reduction, then the number of driven gear teeth of a pair of gear sets that are meshed together The number of driving gear teeth, and then multiply the results obtained.

3. Calculation method of reduction ratio of belt, chain and friction wheel: reduction ratio = diameter of driven wheel and diameter of driving wheel.

The reduction ratio, that is, the transmission ratio of the deceleration device, is a kind of transmission ratio, which refers to the ratio of the instantaneous input speed to the output speed in the deceleration mechanism, which is represented by the symbol "i".

It's not the same. There are 11 kinds of speed ratios in the reducer speed ratio comparison table ZD30, which are 2 4 5 These ten states are a kind of ruler! What do you say is a 1800 with a book height, but I don't know what kind of reducer you are talking about?

The commonly used speed ratios of the Worm Gear Reducer Rv series are 5 10 15 20 25 30 35 40 50 60 80 100, and the common speed ratios of the single-stage planetary reducer are 3 4 5 6 7 8 9 10 and so on. Different reducers commonly use different speed ratios. Speed ratio = motor output speed reducer output speed (speed ratio is also known as transmission ratio) 1

Knowing the motor power and speed ratio and the use factor, find the reducer torque as follows: reducer torque = 9550 * motor power motor power input.

The speed ratio of the reducer is closely related to the effect of the reducer. In this case, it is necessary to consider how fast the reducer can run to better achieve the purpose of deceleration. According to the transmission theory, a larger speed ratio of the reducer usually means that the deceleration effect is more significant, so the speed of the reducer is faster than the general deceleration.

However, this is not the only factor that determines the efficiency of the gearbox. To fully evaluate the deceleration effect, it is also necessary to consider other cause-based lead shafts, such as the gear material used, the strength of the gear, and the arrangement of the gears. In addition, issues such as noise, vibration and energy utilization of the reducer also need to be considered.

Therefore, in this case, it is not possible to simply assume that a larger speed ratio is necessarily better, but also to evaluate the effect of the reducer by considering multiple factors. The size of the speed ratio should be determined according to the specific application requirements, for example, in the elevator, the speed ratio is larger, which can achieve the lifting beat faster; In mechanical automation, the speed ratio is smaller, and subtle movements are more important.

Finally, it can be concluded that the reducer speed ratio is an important factor affecting the deceleration effect to a certain extent, but its advantages and disadvantages depend on the specific application requirements. When selecting a reducer, several factors should be considered to ensure the best results. <>

Summary. Hello <>

Is the speed ratio of the reducer model 20-500 the same? The speed ratio of different types of reducers is different. In the 20-500 model reducer, "20" represents the center height of the input shaft (in millimeters) and "500" represents the torque level of the output shaft, both of which are not directly related to the speed ratio.

In fact, the speed ratio of the reducer is determined by the combination of its internal gears, and the structure and number of internal gears of different models and specifications of the reducer will affect the size of the speed ratio. Therefore, even if the reducer of the same model is different, the speed ratio will be different as long as the combination of its internal gears is different.

Therefore, even if it is the same type of reducer, as long as the combination of its internal gears is different, the speed ratio will be different.

A reducer is a device that converts high-speed, low-torque power into low-speed, high-torque, and is commonly used in various mechanical transmissions. The speed ratio of the reducer refers to the ratio of the speed of the output shaft to the speed of the input shaft, which is usually represented by the symbol i. In different application scenarios, reducers with different speed ratios are needed to meet the requirements of the road.

Take the 20-500 model lead finch gear unit as an example, it has a center height of 20 mm and an output shaft torque class of 500 Nm. When choosing a reducer, in addition to the speed ratio, it is also necessary to consider other factors, such as torque, durability, etc. <>
