Conversion of rotary motion into linear motion has become the need of several fields in industrial sector. Considering this, we'll find a number of companies that manufacture different types and size of actuators to suit different actuation needs.
In this article, we'll come to know about the similarities and differences among major types of linear actuators present in the market.
Mechanical, hydraulic, pneumatic, piezoelectric and electro mechanical are some main types of linear actuators which come with simple working mechanism to support actuation requirements in industries.
Similarities
If we talk about similarities, we will come to know that all types are designed with capable features to support the actuation task needed in the industries. They are made reliable and with durable features to support the task in medical and other industrial area. Companies concentrate on factors like high quality standards and low prices while designing different types of products.
Differences
We all know that different kinds of motion based devices are meant to get used for different tasks. Taking account of this, manufacturers are coming up with products based on different speed, stroke and size.
If we talk about screw technology, actuators are divided on the basis of belt type and screw type. The first category deals the generation of motion through screw and the products based on screw includes ball screws, lead screws and planetary roller screw types devices. Lead screw technology is considered as simple, widely used and economical than other alternatives.
Next difference can be seen in terms of planetary roller screw. The planetary arrangement is meant to increase the surface area to take the load and give the screw its name. The type of devices based on planetary roller screw is known to come with the features of minimal maintenance and at high efficiency.
Rod less or rod style based devices are found several differences in them. In a rodless style, around the screw the housing of device is surrounded to move the load in platform. The rod style actuator is known to produce more force and also excels at thrust type application. On the other hand, the rodless style easily supports the load. One place rod-style based devices are known to be ideal for dirty environments like dusty factory floors and washdown environments.
Thus, from the overall discussions, it can be said that despite of similarities and differences in different types of linear actuators, all motions based devices play a significant role in respective fields.
