Definitions
- the invention relates to a hydraulic cylinder piston with a piston rod and a piston connected thereto.
- connection of piston rod to piston in a hydraulic cylinder is usually made by a preloaded bolted piston.
- a bolted piston with lock nut is usually used.
- This type of connection now requires for large piston diameters a torque during assembly, which can be applied under simple repair conditions difficult and unsafe.
- Another solution consists of a connection of the piston with shaft screws. There is a risk of loosening single screws here. Should you break, There is a risk that they will enter the hydraulic system in the form of small parts and cause malfunctions there.
- the object of the invention is therefore to develop a generic hydraulic cylinder piston such that the piston rod are connected to the piston in a simple and safe manner.
- a hydraulic cylinder piston with the features of claim 1. Accordingly, the piston can be braced against the piston rod via a screw system consisting of two threaded rings.
- the inner threaded ring of the two threaded rings comprises a removable clamping element for applying the bias.
- the male threaded ring is movable relative to the female threaded ring.
- the piston can be connected to the piston rod as follows.
- the internally threaded ring is screwed onto the piston rod on one side of the piston.
- the piston is then biased against the piston rod.
- the clamping element can be removed and the system remains braced. If the connection must be released again, so the piston is removed from the piston rod, in turn, the detachable clamping element is placed on the female threaded ring for releasing.
- the piston can be supported on one side on an inclined shoulder of the piston rod.
- By tightening the clamping element is thus by appropriate Sliding the piston on the inclined plane generates the corresponding voltage.
- the removable clamping element may consist of a clamping ring with screws provided on the circumference. Alternatively, the screws can also be screwed directly into the inner threaded ring.
- a thread for generating the relative movement between the inner and outer threaded ring is arranged.
- a projection or a nose is respectively arranged on the inner threaded ring or on the outer threaded ring, so that the screw system consisting of the two threaded rings can be loosened as a whole.
- FIGURE shows a longitudinal section through the end portion of a hydraulic cylinder piston, which consists of a piston rod 10 and a piston 12, which are arranged in a hydraulic cylinder not shown here.
- the piston rod 10 has at its one end a shoulder 14 which carries an external thread 16.
- a recessed in diameter portion 18 which merges via a bevel 20 to the nominal diameter of the rest of the piston rod.
- the piston 12 is in the manner shown in the figure.
- the piston 12 has a circumferential recess 22.
- a screw 24 can be screwed, which consists of an internally threaded ring 26 and an externally threaded ring 28. Both threaded rings 26 and 28 are movable against each other via a screw thread.
- the female threaded ring 26 has a tab or projection 30 which secures the male threaded ring 28 on the female threaded ring 26.
- the inner threaded ring 26 carries as a clamping element around the circumference clamping screws 32nd
- the piston 12 can be biased and held.
- the inner threaded ring 26 is clamped defined with the clamping screws 32 screwed into it with the piston 12.
- the correspondingly defined voltage can be applied by the torque of the screws 32.
- the male threaded ring is moved over the female threaded ring toward the piston until it abuts the piston. Then it can be tightened with a given torque.
- the clamping element forming screws 32 are then removed and the entire system, that is, the piston 12 remains clamped on the piston rod 10. To release the clamping element consisting of the screws 32 is used again, so that the above steps occur in reverse order.
