Fundamental
Use each gear transmission to achieve the purpose of speed reduction. The driving force of the motor, internal combustion engine or other high-speed operation is reduced according to the gear on the input shaft of the reducer with a small number of teeth meshing with the large gear on the output shaft to achieve the purpose of speed reduction. Ordinary reducers also have several pairs of the same basic principle transmission The gear is ideal. The DC Gear Motors Manufacturers plays the role of matching speed ratio and transmission torque between the prime mover and the working machine or electric actuator. It is a relatively precise machine.
1. Features: With reverse locking function, it can have a larger transmission ratio. The input shaft and output shaft are not on the same axis or on the same plane.
2. Function: Reducer is generally used for motor equipment with low speed ratio and large torque. Reduce speed and increase output torque at the same time. The torque output ratio is the motor output multiplied by the transmission ratio, but it must be noted that the rated torque of the reducer cannot be exceeded.
3. Application: The product categories involved in the reducer industry include various gear reducers, planetary gear reducers and worm reducers, as well as various special transmission devices, such as growth speed equipment, speed control equipment, and Various composite transmissions within flexible transmissions, etc.
Speed ratio calculation method of reducer
1. Define the calculation method: transmission ratio = input speed ratio ÷ output speed ratio, the ratio of the connected input speed ratio and output speed ratio, if the input speed ratio is 1500r/min, the output speed ratio is 25r/min, then the transmission The ratio is: i=60:1
2. Calculation method of transmission gear system: transmission ratio = number of driven transmission gear teeth ÷ number of active transmission gear teeth (if it is a multi-level transmission gear decelerating, then the number of driven gear teeth of a pair of gear sets ÷ driving wheel The number of teeth, and then multiply the result.
3. Calculation method of transmission ratio of transmission belt, transmission chain and friction wheel: transmission ratio = driven wheel diameter ÷ driving wheel diameter. The working condition index is determined according to actual application conditions such as daily working hours, impact load, switching frequency, etc. The index is not a fixed value. The applicable power is usually the applicable power of the servo motor models on the market. The applicability of the reducer is very high, and the index can be maintained above 1.2 during work, but the selection can also be determined according to your own needs. The output shaft diameter of the selected servo motor cannot be larger than the large application shaft diameter in the table. If the torque is calculated, the speed ratio can be considered for normal operation, but when the servo motor’s full output is insufficient, the drive on the motor side can be used for current limiting control or torque protection on the mechanical shaft.
Transmission ratio calculation method: transmission ratio = input speed ratio ÷ output speed ratio, the ratio of the connected input speed ratio and output speed ratio, if the input speed ratio is 1500r/min, the output speed ratio is 25r/min, then the transmission ratio is For: i=60:1. Transmission gear system calculation method: transmission ratio = number of driven transmission gear teeth ÷ number of active transmission gear teeth (if it is a multi-level transmission gear decelerating, then the number of driven gear teeth of a pair of gear sets ÷ the number of driving gear teeth, Then multiply the results obtained. The calculation method of the transmission ratio of the transmission belt, transmission chain and friction wheel: transmission ratio = driven wheel diameter ÷ driving wheel diameter. Reduce speed and increase output torque at the same time. The torque output ratio is based on the motor output multiplied by the transmission However, be careful not to exceed the rated torque of the reducer.
