The scope and characteristics of worm gear reducer and its working mode
Hits:451         Date:2020-07-25
Worm gear reducer is a mechanical device with a wide range of applications
The structure of worm gear reducer is roughly divided into three parts: box, worm gear, bearing and shaft combination. These three parts support each other to achieve work efficiency.
The biggest advantage of worm gear reducer is that it has self-locking function, relatively small size, relatively high precision, easy installation, low energy consumption, compact structure, and large transmission ratio. It is one of the reducers commonly used by all of us.
Everyone knows that the general working principle of the reducer is to increase the torque, and in special circumstances it acts as a speed increaser. The same is true for worm gear reducers, which use a speed converter to reduce the rotation speed of the motor to increase the torque. In order to improve work efficiency, worm gear reducers generally use non-ferrous metals as worm wheels and harder steel as worms.
The applicable scope of worm gear reducer is as follows:
1. The speed of the high-speed shaft is not more than 1500 rpm.
2. The peripheral speed of the gear drive is not more than 20 m/s.
3. The working environment temperature is -40~45℃. If it is lower than 0℃, the lubricating oil should be preheated to above 0℃ before starting. This reducer can be used for forward and reverse rotation.
The following are the characteristics of worm gear reducer:
1. The gear is made of high-strength low-carbon alloy steel by carburizing and quenching. The hardness of the tooth surface reaches HRC58-62. The gears are all geared with grinding technology, with high precision and good contact.
2. High transmission efficiency: the third level is greater than 90%.
3. Low noise and stable operation.
4. Small size, light weight, long service life and high carrying capacity.
5. Easy to install, easy to disassemble and inspect.
Worm gear reducer adopts aluminum die-casting box body, mode structure, small size and light weight, can well combine all accessories and devices, and secondly, it is directly installed on the input shaft on the machine side to save a lot of installation space , It can be installed directly without transmission parts, which shortens the assembly time and reduces the overall cost. It is also very convenient in debugging and installation. It combines motor or brake motor, stepless speed changer and other motorized devices, and installs with flange or torque arm, so that the speed can be adjusted according to the needs in the load, which is convenient and saves trouble! This type of reducer is a very good choice in modern automatic transmission devices.
