Specific characteristics of swing cylinder structure
The swing oil cylinder is divided into three types of structure: rack and pinion, vane, and spiral. Compared with the traditional rack and pinion swing cylinder and vane swing cylinder, it has a compact structure, a small footprint, safe and reliable, maintenance-free, high pressure , Obvious advantages such as no leakage, great output torque, strong power, accurate positioning and easy control. The following describes the specific characteristics of the swing cylinder.
Rack and pinion type: The linear oil cylinder drives the rack to reciprocate, so as to realize the swing of the gear meshing with the rack. It is suitable for transmitting large torque, simple installation, convenient use and low price.
Blade type: The blades are arranged radially, and the hydraulic oil acts on the blades to realize the rotation of the drive shaft. The moment of inertia is small, the action is sensitive, and the rotation uniformity is small.
Spiral type: Through the internal spiral of the shell and the external spiral of the spline sleeve, the internal spiral of the spline sleeve and the external spiral of the output shaft (flange), the relative movement between the two pairs of spiral pairs achieves the shaft Blue) output rotation. Compact structure, accurate swing angle and high reliability. Smooth operation and extremely low speed.
Swing cylinders are even used in the pharmaceutical and food processing industries that require high cleanliness and health care.
