Abstract
The utility model discloses a flexible leak-less hydraulic cylinder, which belongs to a leak-less hydraulic cylinder in the mechanical hydraulic transmission system. The flexible leak-less hydraulic cylinder is characterized in that the flexible leak-less cylinder is internally provided with elastic capsules which make the working fluid completely isolated with a dynamic sealing component and a static sealing component. Accordingly, probable factors which can cause the leakage can be eliminated; complete leakage-proof can be realized; simultaneously, the structure is made to be more simplified, and accordingly, the flexible leak-less hydraulic cylinder is suitable for all kinds of the hydraulic machines.
Description
The utility model is the soft oil hydraulic cylinder in a kind of mechanical-hydraulic transmission system.
Oil hydraulic cylinder in the Hydraulic Power Transmission System owing to have leakage problem, influences the service behaviour of oil hydraulic cylinder.As be used for the oil hydraulic cylinder of machining aspect, and owing to leak, cutter will appear gnawing, phenomenons such as vibration influence the machining accuracy of part.Oil hydraulic cylinder in the food processing machinery leaks, can contaminated food products.The oil hydraulic cylinder that is used for precision type instrument owing to leak, will influence the precision of instrument.
The way that existing minimizing oil hydraulic cylinder leaks, normally adopt dynamic seal such as rod seal circle, piston packing, scraper ring and end cap with seal ring, piston with seal ring, guide sleeve with static seal such as seal rings, prevent or reduce leakage.But it is impossible that oil hydraulic cylinder is not leaked, and along with the wearing and tearing of Sealing, various environment, condition change, and will increase in various degree leak.
The purpose of this utility model provides the soft oil hydraulic cylinder of a kind of zero leakage, and it not only can make oil hydraulic cylinder not leak fully, and the manufacturing of oil hydraulic cylinder and assembly technology are simplified, and applicability is wider.
Fig. 1 is a principle sectional view of the present utility model.
Fig. 2 is the schematic representation of a kind of elastic capsule of the present utility model.
Fig. 3 is the hydraulic fluid port of elastic capsule in the utility model, the connection diagram of venting gas appliance.
Flexible leakless hydraulic cylinder of the present utility model, as shown in Figure 1, it is by cylinder barrel (7), cylinder cap (2) and (10), piston (5), piston rod (6) forms; Column elastic capsule (4) or annular resilient capsule (8) are housed in cylinder barrel, working solution passes into the course of work that realizes hydraulic cylinder in the elastic capsule, working solution and dynamic seal and static seal are kept apart fully like this, have eliminated the possibility Factors Causing Electrolyte Creepage and Leakage, thereby realize zero leakage.
The utility model is installed in the elastic capsule in the oil hydraulic cylinder, can make different shape as required, is preferably made the cylindricality elastic capsule and the cylinder shape elastic capsule of helical corrugation tubulose, shape as shown in fig. 1.Perhaps make a kind of dolioform a section cylindricality elastic capsule and cylinder shape elastic capsule, as shown in Figure 2.Working solution enters elastic capsule from hydraulic fluid port pipe (3) or (9), and the gas in the elastic capsule is discharged by stoma tube (1) or (11), and elastic capsule is oppressed piston (5) again, realizes motion.Because elastic capsule work the time is and cylinder barrel (7), cylinder cap (2) and (10), piston (5), piston rod (6) are immediate, and suffered resultant pressure is zero.Elastic capsule is formed by inner glue layer, enhancement layer, outer glue-line MULTILAYER COMPOSITE.Elastic capsule should be according to the working solution difference of selecting for use, and the flexible material that optional usefulness has oil resistance, wear resistance performance, heat resistance, winter hardiness and a chemical resistance is done the inner glue layer and the outer glue-line of elastic capsule; Select for use the good cotton of flexibility, fiber crops, cellulose ester, polyester, nylon, aromatic polyamides and ramuscule steel wire to make enhancement layer.The good ramuscule steel wire (12) that becomes the angle of inclination to arrange of preferably selecting synthetic rubber and flexibility for use the elastic capsule that is composited.The physical dimension of elastic capsule can decide according to the size of oil hydraulic cylinder.
Subordinate list 1 is the flexible material of selecting for use according to working solution commonly used.
