What s the deal with geared motors? What does it slow down through?

Advantages: Because the structure is more compact than the staggered shaft helical gear mechanism, the transmission ratio between the staggered shafts can be very large. The transmission contact mode is different from other types of reducers, which is line contact, low noise and stable transmission; It has the function of reverse self-locking, that is, the worm gear can only be driven by the worm, and the worm gear cannot drive the worm, so it is often used in lifting or other occasions that require self-locking.

Defect: General efficiency =0

The common specifications, from the diameter as thick as a finger to the elevator traction machine, are all geared motors.

The function is to generate a driving torque with a suitable speed.

Because the electromagnetic torque of the motor is small, the speed of the motor is relatively high compared to most loads, so it is necessary to match the conversion, which is equivalent to the transformer and the transmission of the bicycle.

There is a deceleration mechanism inside the optical drive, which is external.

A geared motor usually refers to a structure that is manufactured in an assembly with an electric motor.

High assembly density and high performance, there are stators and rotors that are directly turned into reducers, and there are harmonic and flexible gear structures, which are rare because of manufacturing difficulties and high requirements for materials. Planetary deceleration mechanism has a few percent application rate, for example, some electric screwdrivers, which are small in size. Usually there are many helical gears, spur gears, and curved gears that are decelerated, for example, there is a reducer in the hand electric drill.

The first indicator of the reducer is the deceleration ratio, and then the torque, which is the speed.

The other frame numbers are size and structure.

The geared motor is a motor output terminal connected to a reducer.

The main parameters are, of course, the reduction ratio, the output speed, and the output torque.

The effect is very clear, you need a speed of tens of revolutions per minute, the motor is not easy to achieve, you need to slow down, while providing a large torque.

1. It's rpm, not revolutions per minute.

2. The speed of the motor is 1000rpm, the speed of the equipment is 4rpm, and the transmission ratio.

It is 250:1. The reducer is: 1, which means that there are deceleration structures behind the reducer, such as gears, chains, belts, etc.

3. Replace with: 1 reducer, reduction ratio.

If the other structures do not change, the speed of the equipment should be increased, that is, greater than 4rpm.

4. The speed of the equipment should be 4*, but the actual speed is, indicating that the intermediate transmission structure has changed.

The reduction ratio of the reducer is 10:1, that is, the input is 10 revolutions and the output is 1 revolution, so if the motor is 3000 revolutions per minute, after deceleration, it is 3000 10=300 revolutions.

Reduction ratio = input speed Output speed. The ratio of the input speed to the output speed of the connection. Motor power = torque 9550 motor power input speed ratio use factor.; 1x60=60m/min；60÷；Gear ratio = 1490.

Reduction ratio = input speed Output speed. The ratio of the input speed to the output speed of the connection. Motor power = torque 9550 motor power input speed ratio use factor.; 1x60=60m/min；60÷；Gear ratio = 1490.

Questions. The speed ratio of the motor 1500 revolutions, the speed ratio of the reducer, is 50, and the output shaft of the reducer is how many revolutions per second.

The speed ratio of the motor 1500 revolutions, the speed ratio of the reducer, is 50, and the output shaft of the reducer is how many revolutions per second.

Output 30 rpm.

Questions. How many speed ratios are required for the output shaft of the reducer to make 2 revolutions per second.

How many speed ratios are required for the output shaft of the reducer to make 2 revolutions per second.

1500 revolutions per minute, 25 revolutions per second, 2 revolutions per second.

Reduction ratio: 1 question. 70:1 deceleration output shaft how many revolutions per second.

70:1 deceleration output shaft how many revolutions per second.

Motor 1500 rpm reducer 70:1 reducer output shaft per second how many revolutions.

Motor 1500 rpm reducer 70:1 reducer output shaft per second how many revolutions.

A reduction ratio of 70:1 with the same motor speed equals less than half a revolution per second.

Questions. Okay

Okay, please give a thumbs up.

The motor deceleration method usually adopts two methods: reducer and inverter. The reducer is also known as the reducer and the reducer; The function of the reducer is to reduce the speed, increase the torque, reduce the inertia, and is used to connect the motor and the equipment of a mechanical transmission device. Reducers are divided into gear reducers and planetary reducers according to their functions and structures.

According to the material, it is divided into speedy material and plastic material; Regardless of the gear, planetary, metal, plastic reducer detailed performance, parameters are not the same, the following are the common characteristics of the reducer:

Rotten reduction speedmaker is manufactured in combination with technical requirements.

Space-saving, reliable and durable, with the ability to withstand overloads.

Low energy consumption. Low vibration, low noise, energy saving, high-quality section steel materials (or special materials) are selected, rigid cast iron box, and the surface of the gear is treated with frequency heat.

After precision machining, positioning accuracy, all this constitutes a gear transmission.

The gear reducer motor of the assembly is equipped with various motors and small motors.

The product uses the design idea of serialization and modularization, and some adaptability, this series of products has many motor combinations, installation positions and structural schemes, and can be selected according to actual needs at any speed and various structural forms.

It is widely used in the mechanism of transmitting power and motion, and it uses the speed converter of the gear to decelerate the number of revolutions of the motor to the required number of revolutions and obtain a large torque of the empty leakage mechanism. Sophobia.

How does the geared motor achieve deceleration? The process of deceleration of the geared motor is also the process of this normal work, so the motor is accelerated after the end of the Zhao Sui Tong will have an adaptation process.

Geared motor refers to the integration of reducer and motor (motor). This type of integration is also often referred to as a gear motor or gear motor. It is usually integrated and assembled by a professional reducer manufacturer and supplied in complete sets.

Geared motors are widely used in the steel industry, machinery industry, etc. The advantages of using geared motors are that they simplify the design and save space.

The main functions of the reducer are: 1) reduce the speed and increase the output torque at the same time, and the torque output ratio is multiplied by the reduction ratio according to the output of the motor, but it should be noted that the rated torque of the reducer should not be exceeded.

How it works. The reducer is generally used for low-speed and high-torque transmission equipment to put the motor. The power of the internal combustion engine or other high-speed operation through the input of the reducer The gear with a small number of teeth on the shaft meshes the large gear on the output shaft to achieve the purpose of deceleration, and the ordinary reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect, and the ratio of the number of teeth of the large and small gears is the transmission ratio.

Not a concept.

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, with symbols"i"Denote.

1. Define the calculation method: reduction ratio = input speed output speed. Reduction ratio.

2. General calculation method: reduction ratio = use torque 9550 motor power motor power input speed use coefficient.

3. 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.

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