Use and maintenance of saw blade motor
2022-9-9
Saw motorIt is a power transmission mechanism that uses a geared speed converter to reduce the number of revolutions of the motor (motor) to the desired number of revolutions and obtain a larger torque. The saw blade motor is also called a micro geared motor, and the saw blade motor has the functions of deceleration and torque addition, so it is widely used in speed and torque conversion equipment.
The saw blade motor is composed of gear pairs at all levels. For example, the small gear can be used to move the large gear to achieve a certain deceleration intention. Then the multi-stage structure can be used to greatly reduce the speed. Therefore, in general, the saw The working principle of the chip motor is to use all levels of gear transmission to achieve the purpose of reducing speed. It is generally used in low-speed and high-torque transmission equipment, and the power of the motor, internal combustion engine or other high-speed work is passed through the gear with a small number of teeth on the input shaft of the speed reduction belt to engage with the large gear on the output shaft to achieve deceleration. Intentionally, the general geared motor will also have several pairs of gears with the same principle to achieve the desired deceleration effect.
The transmission of the saw blade motor is a high-precision transmission, and the transmission efficiency is high. Although there are many ways to achieve deceleration, the most commonly used method is gears to decelerate, because the gears can not only reduce the space occupied and reduce costs. Therefore, some people call the geared motor a micro gearbox. Generally, the gearbox is a combination of some gears. Because the gearbox itself has no power, it needs a drive component to drive it. The biggest purpose of using a geared motor as a transmission part is to achieve power transmission, obtain a certain speed and obtain a large torque. Therefore, geared motors are now widely used in various occupations.
According to the relevant query data, about 80% of the gear parts of the reduction motor are damaged due to friction and wear. The conflict can be reduced by reasonably selecting a good conflict pair, and a reasonable smoothness can also be selected, which can also reduce the conflict damage of the gears. Smoothing is to use a material to isolate the surfaces that move relative to each other. This material has low friction resistance and causes less wear. The only effect of lubricating oil in gear transmission is to reduce friction resistance and reduce wear, so as to prolong the service life of mechanical parts as much as possible.
Definition of Positioning Accuracy of Small Saw Blade Motor
When each physical quantity is to be represented by a numerical value, it is necessary to draw up a specification and select a unit. The formulation of specifications and units is to exchange knowledge about physical phenomena between people, and the micro-motors we produce are no exception and have their shape and position accuracy.
1. The shape and position accuracy of the small saw blade motor: the shape and position accuracy includes straightness, flatness, roundness, cylindricity, parallelism, straightness, coaxiality, etc.
2. When reviewing, according to the position and effect of the part in the machine, refer to similar drawing materials, and review its shape, position, service item and service value to determine whether it is reasonable.
3. When reviewing, it should be noted that the relationship between dimensional accuracy and shape and position accuracy, that is, a certain dimensional accuracy must have corresponding shape and position accuracy.
4. If the ovality is too large, it is difficult to obtain an accurate diameter.
The shape and position accuracy level of the small saw blade motor is distinguished by the percentage of its allowable error in the dial scale value.
