How to measure whether the stability of a pneumatic motor is good or not is a problem concerned by many buyers. Now the common pneumatic motors on the market are mainly composed of pneumatic host, pneumatic guide rail, pneumatic gear rack or ball screw, pneumatic transmission mechanism and other components. Let's make a simple analysis from these components.

The main engine is composed of a beam and two longitudinal end frames. The gantry of the machine is composed of an end frame and a cross beam. The cross beam adopts a rectangular square tube structure, which is tempered to remove internal stress and has high strength and rigidity. Multiple mobile trolleys can be installed on the cross beam. Drag chains are used for lateral moving devices

The mechanical part realizes high-precision gear rack transmission. The guide rail is refined from high-precision special imported guide rail. The precision processed sliding guide rail is fastened on the concrete or steel frame foundation with support, and is equipped with adjusting bolts for installation and adjustment. Longitudinal drive

The system is installed in the longitudinal end frame, and the design of low position makes the transmission more reasonable and stable.

There are two front and rear rolling wheels at the bottom of the longitudinal end frame, which can roll smoothly along the guide rail. The front and rear ends are equipped with guide rail scraper to ensure that there are no sundries on the guide rail surface. Eccentric clamping wheels with guiding function are installed on both sides of the bottom. In order to ensure the guiding accuracy of the machine, the laser cutting machine The cutting torch lifting and lowering are equipped with high-strength linear guide rail (horizontal transmission or high-precision fine grinding guide rail). The precision machined gears and racks ensure the vertical and horizontal transmission accuracy of the machine and eliminate the gap.

Taking the D301 pneumatic motor produced by maiyang as an example, the machine adopts gantry structure, high-strength aluminum alloy tensile beam, precision linear guide rail and helical gear transmission system. The machine has good overall rigidity, stable performance and stable operation.

The most important thing to judge whether the motor shakes abnormally is whether it shakes pneumatically!
