One JWM type (trapezoidal screw type)
Low speed, low frequency
JWM type (trapezoidal screw type) is suitable for low speed and low frequency occasions. The main components are: precision trapezoidal screw pair and main precision worm gear pair.
1. Economy
Compact structure, simple operation and convenient maintenance.
2. Low speed and low frequency
It is mainly used in places with heavy load, low speed and no frequent work.
3. Maintain the load: the trapezoidal screw has an automatic locking function, which can maintain the load even without a braking device.
When subjected to large vibrations and shock loads, the self-locking function will occasionally fail, and a braking device must be added at this time.
Two JWB type (ordinary ball screw type)
High speed, high frequency
JWB type (ordinary ball screw type) is suitable for high-speed, high-frequency and high-performance devices. The main components are precision ball screw pair and high-precision worm gear pair.
1. High efficiency: the use of rolling friction improves the efficiency of the whole machine, and only a small driving source is needed to generate a great driving force.
2. High-speed: Compared with the trapezoidal screw, the speed is greatly improved, and it can run easily and at high speed.
3. Long service life: The use of high-quality ball screw can increase the working life by more than 3 times.
Note: ① It has no self-locking function, it needs to add a brake device or select a drive source with brake.
②The JWH large pitch ball screw type will be consulted separately.
