With the development of science and technology, people's living standards improve, people's demand for consumer goods is becoming more and more diversified, intelligent, comfortable, intelligent products with mechanical movement function, Micro Gear Motor the motor function is inseparable from the drive, leave the gear transmission, micro gear reducer drive scheme is widely used in intelligent products.
In the process of product development, product structure engineers with gearbox transmission scheme, often confused about, don't know where to start, many structural engineer with the progress of precision gear reducer r&d engineers, performance is also very helpless. The progress of precision micro gearbox r&d engineers to tell you, what should be considered in the design of the micro gearbox which parameters
1. According to the product structure and size. Low Rpm Electric Motor Only product structure engineers know the structure of the product and size, just know the demand of the product, just know how much the micro gear reducer; Product structure and determine the size, in order to determine with planetary gear reducer is parallel shaft spur gear box. At the same time, also want to consider the fixed method of gear box.
2. Want to consider the output requirements of micro gear reducer, the output requirement includes, output torque and load torque when there is no load output speed, these parameters are closely related to the performance of the product.
3. Want to consider the choice of motor. Motor, the choice of parameters have to consider, motor speed, service life, noise, current, etc.; The type of motor (including the hollow cup motor, stepping motor. A brushless dc motor, brushless dc motor). Must have the motor specification, the power curve in the specifications can response performance of the motor.
4. Input and output parameters are decided, will determine the reduction ratio. Is a single stage, secondary or tertiary, and even more levels of slowing down.
5. Reduction ratio is determined, consider each gear, the center distance between the combination of input and output requirements, considering the gear material and the shape of the gear, such as the amount of gear teeth, choose or straight tooth bevel, Gear Reduction Motor how much is the thickness of the gear.
6. In the process of the micro gear reducer design, also consider, noise, life, current, the use of the environment, and bearing capacity.
Plastic gear reducer is through the transmission gears, reduce the high speed of the motor to the designer's demand goal, at the same time, increase the output torque, in order to meet the requirements of product use. At the completion of this action, the gear play a key role. Gears involves all kinds of gear, gear in different locations, their function is different also, the shape is different also, for example, the motor gear, spur gear can be selected or worm, other position of gear can choose single or dual gear, gear or even triple gear; According to the demand, is likely to be standard may also have standard tooth. Material according to the actual requirements of the gear, can choose plastic or metal or powder metallurgy.
