Abstract
The invention provides a heat dispersion disk sheet clearance support system for a disk type heat dispersion machine. A piston rod is hollow; a transmission shaft can penetrate the inner cavity of the piston rod; a bearing mounting position is arranged at the rear end of the inner cavity of the piston rod; the interior of the cylinder sleeve is convex, so that the cylinder sleeve is divided into a front work cavity and a back work cavity of which the inner diameters are the same; the inner diameter of the front end of the cylinder sleeve equals to the outer diameter of the protrusion at the front end of the piston rod; the inner concave part in the middle of the piston rod and the inner convex part of the cylinder sleeve work in a matched manner; the length of the inner concave part of the piston rod is larger than that of the inner convex part of the cylinder sleeve; a distance fixing sleeve for positioning the stroke of the piston rod is arranged between the piston rod and the rear end of the cylinder sleeve in a sleeving manner. The heat dispersion disk sheet clearance support system adopts a double-acting hydraulic cylinder with the hollow piston rod instead of two hydraulic cylinders, so as to effectively solve the problem of driving the two hydraulic cylinders synchronously; the two hydraulic cylinders are driven to be synchronous stiffly while the single hydraulic cylinder is driven to be synchronous completely.

Background technique
The heat of existing disc-type heat dispersing machine disperses disc gap back-up system to be made of 2 oil hydraulic cylinders, utilizing 2 hydraulic cylinder synchronous to drive Moving plate moves, adopt 2 hydraulic cylinder synchronous to drive the Moving plate that heat is disperseed disc, because double hydraulic cylinder is that a kind of rigidity is synchronous, therefore the situation such as interfere easily, not steady, in case wearing and tearing are uneven, then interference, unbalance situation will further worsen.Owing to adopt double hydraulic cylinder to drive, then the bearing support between two transmission shafts exists the leakage of oil point of easy generation seal failure simultaneously.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and a kind of Complete Synchronization of realizing is provided, and the heat that can solve a kind of disc-type heat dispersing machine of leakage of oil, sealing is disperseed disc gap back-up system.
A kind of heat of disc-type heat dispersing machine is disperseed disc gap back-up system, its structure outline is: include one single hydraulic cylinder, described single hydraulic cylinder includes piston rod, cylinder sleeve, spacer sleeve and stationary gland, described piston rod is hollow piston rod, transmission shaft can pass the inner chamber of piston rod, the rear end of piston rod cavity is provided with the bearing installation position, described cylinder sleeve is the cylinder sleeve of interior convex, the cylinder sleeve of interior convex is divided into the active chamber that former and later two internal diameters equate with cylinder sleeve, the cylinder sleeve front inner diameter equates with the external diameter of piston nose projection, the work that matches with the interior protuberance of cylinder sleeve of the inner fovea part at piston rod middle part, the length of piston rod inner fovea part is longer than the length of the interior protuberance of cylinder sleeve, the rear portion of piston rod and cylinder sleeve be arranged with spacer sleeve for the positioning piston throw of lever between the two, the maximum outside diameter of spacer sleeve equates with the internal diameter at cylinder sleeve rear portion, spacer sleeve cooperates connection with piston rod, stationary gland lock onto the end face of piston rod, the end face of spacer sleeve is close proximity to the end face of stationary gland, be provided with the gap between stationary gland and the piston rod end face, the inner chamber of stationary gland is hollow to make things convenient for transmission shaft to pass through, rearward end at cylinder sleeve is provided with the tapped hole that can connect with dispersion machine sports association usefulness, in cylinder sleeve before the protuberance, rear side is provided with along the place for oil-feed or fuel-displaced filler opening or oil outlet.
The heat of disc-type heat dispersing machine of the present invention is disperseed disc gap back-up system, single hydraulic cylinder is arranged to the shape of hollow conveniently to pass transmission shaft, cylinder sleeve is static when simultaneously the tapped hole of cylinder sleeve by tail end being connected work with body does not move, the interior protuberance of cylinder sleeve and the contacting part of piston rod inner fovea part consist of working surface, because the length that the length of piston rod inner fovea part is longer than the interior protuberance of cylinder sleeve, therefore the interior protuberance by cylinder sleeve is divided into former and later two active chambers with cavity between the two, when the active chamber oil-feed that is positioned at front end, when being positioned at the active chamber oil extraction of rear end, piston rod will be with spacer sleeve, stationary gland is mobile backward, when the oil extraction of front end active chamber, during rear end active chamber oil-feed, piston rod will be with spacer sleeve, stationary gland moves forward, thereby play the driving effect of former double hydraulic cylinder, and can realize Complete Synchronization, having overcome original two cylinder pressures is the synchronous shortcoming of bringing of rigidity, has also solved simultaneously because the oil leak point that adopts double hydraulic cylinder need adopt two transmission shafts to bring
Adopt the multiple axle of spacing parallel arranging to seal with seal ring in the described cylinder sleeve between protuberance and the piston rod inner fovea part.
Adopt the O-ring seals sealing between spacer sleeve and the piston rod.
Adopt the hole to seal with seal ring between spacer sleeve and the cylinder sleeve.
The front end of cylinder sleeve and piston rod adopts the hole to seal with seal ring.
In sum, the present invention's following advantage compared to existing technology:
The heat of disc-type heat dispersing machine of the present invention is disperseed disc gap back-up system, it is middle hollow double-acting hydraulic cylinder that heat disperses disc gap back-up system to become 1 piston by 2 cylinder design, efficiently solve the difficult problem that 2 hydraulic cylinder synchronous drive, double hydraulic cylinder is that rigidity is synchronous, and single hydraulic cylinder then is Complete Synchronization.While combines as a whole the spindle bearing holder that front and back separate by the piston of middle hollow (pipe box shape) again, has solved original 2 leakage of oil points when the lubricious seal failure of two drive bearing blocks, so that system's operation is more safe and reliable.
