Pneumatic cylinders single-acting magnet and the magnetic sensor under the shell on a common base With subpiston space connection to the ATMOSPHERE

摘要

Technical result which is achieved when implementing the proposed pneumatic single-acting with a magnet and a magnetic sensor having a base in which the hermetically mounted housing pneumatic cylinder with magnetic piston rod, and the top housing covered envelope which is hermetically connected to the base and having a connection via a collet fitting and hose a source of compressed air, and in conventional pneumatic cylinder or the subpiston space connected to compressed air returns to its initial position voltage or has a return spring. Since the proposed pneumatic cylinder is a single acting uses compressed air in one direction and provides a constant pressing mechanism for transferring force uniformly over the entire length of the working stroke of the piston, irrespective of the wear of the friction surfaces, and for a long time, it eliminates the use of (a spring or compressed air under the piston to return in its original position), and to avoid creating resistance to the piston when transferring the pressure on the friction surface, the subpiston space connected with the atmosphere. Since the magnetic sensor is attached to the body of the air cylinder from the outside and to protect it from the action of extraneous magnetic fields and mechanical damage to the housing shell is worn, it is designed as a hollow cylinder having an inner diameter and provides a mounting location of the magnetic sensor. Conclusions magnetic sensor is hermetically sealed with the base in a yield outwardly so that the membrane provide tightness and feeds the signal to an information panel which fixes the position of the piston in the air cylinder body. On the outer surface of the shell has a retainer Spent air cylinder at a certain position in the apparatus, constant force transmission mechanism, for example in the brush holder body, the rod providing access to the full piston stroke. At the end of the pneumatic cylinder working cycle, it turns off the compressed air supply to pneumatic cylinder - by detaching the hose from the fitting and the collet piston manually returned to its original position. Replace worn components or transmission mechanism (e.g., brush holder) constant force on the friction surface on new (electrobrushes, eat through or collector slip rings, etc.). All of the foregoing increases improving the design of pneumatic single acting with a magnet and a magnetic sensor position of the piston under the shell with subpiston space connected with the atmosphere, its availability, safety, reduces maintenance and repair time, provides a device Controlled wear of friction surfaces, uniform pressing and wear the structural elements force transmission irrespective of the wear of the rubbing surfaces.
