Lead screw vs belt: how to choose?

Lead screw and belt are both types of mechanical components used for linear motion applications.While belt and lead screw usually serve the same purpose,their different characteristics make them suitable for different types of applications.So lead screw vs belt:how to choose?We can simply refer to the following advantages and disadvantages of belt and lead screw.


Belt Pulley


high speed belts


Lead Screw 10mm diameter


various lead screw form ALM



●Belt advantage and disadvantages

1.Advantages
(1)Smooth transmission:smooth belt transmission,no impact and noise,suitable for high-speed transmission.


(2)Easy adjustment:It is very convenient to replace the belt and has higher flexibility.


(3)Cheap price:compared with the lead screw,the price of the belt is cheaper.


2.Disadvantages

(1)The accuracy is not high:the belt transmission accuracy is not as high as the lead screw,and it is easy to relax after a long time of use,resulting in transmission error.


(2)Limited life:the life of the belt material is limited,and the conventional inspection needs to be replaced,which has industrial safety risks.


(3)Single force direction:the belt is a one-way transmission,can only withstand the same direction of the transmission of power,can not reverse operation.


Lead screw advantage and disadvantages

1.Advantages
(1) High precision:the
lead screw transmission precision is high,the error is small.


(2) Easy adjustment:The lead screw is easy to adjust and can be carried out manually or automatically.


(3) Long life:the lead screw material has a long life and does not need to be replaced often.


2.Disadvantages

(1) Higher price:The price of the lead screw is higher than that of the belt.


(2) Loud noise:the lead screw transmission noise is larger,not suitable for use in noise sensitive occasions.


(3) Easy to stick:In a dusty and oily environment,the lead screw is prone to stick.


In actual use,it should be selected according to the requirements of the transmission,the use of occasions,economic benefits and other factors.
If you need high-speed,large power transmission and accuracy requirements are not high,you can choose belt drive;If you require high precision,large load,and long service life,you can choose lead screw drive.
