Embodiment
In order to make technical problem to be solved in the utility model, technological scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Figure 1 shows that the schematic representation of off-course brake 100 among the utility model one embodiment.As shown in Figure 1, off-course brake comprises first matrix 110 and second matrix 120.First matrix 110 and second matrix 120 can fit together by screw rod 112 etc.
In the embodiment shown in fig. 1, first matrix 110 is identical with the structure of second matrix 120, and first matrix 110 and second matrix 120 are symmetrical arranged.Be the concrete structure that example illustrates first matrix 110 and second matrix 120 with first matrix 110 below.
Above-mentioned is the concrete structure of off-course brake 100 among the utility model one embodiment, its working principle of brief description.
When off-course brake 100 needs work, pressure oil enters oil cylinder 130 and promotes plunger 140 motions through oil supply pipeline 132, plunger 140 withstands brake block 190 and passes to a brake disc between the brake block of the brake block 190 that is arranged on first matrix 110 and second matrix 120, makes the brake disc braking brake.
When machinery requirement turned round, the pressure oil in the oil cylinder 130 was through 134 releases of emptying pipeline, and brake block 190, has a machine in operation from gap of brake disc at the effect bottom of rolling brake dish.
In said process, the wet goods influence if plunger 140 is under pressure and be subjected to time spent of doing of radial force, first friction ring 160 and second friction ring 170 can alleviate or eliminate the radial force that 140 pairs of Sealings 150 of plunger apply, and prevent that Sealing 150 from damaging, thereby prevent oil cylinder 130 leakage of oils.Especially, when pressure oil can apply moment resulting from sidesway to plunger 140 when oil supply pipeline 132 enters oil cylinder 130, first friction ring 160 bears relative less action force and second friction ring 170 bears relatively large active force, therefore, adopt thinner and the structure that second friction ring 170 is thicker of first friction ring 160, both can alleviate or eliminate the radial force that 140 pairs of Sealings 150 of plunger apply and damage to prevent Sealing 150, again escapable costs.
As mentioned above, the utility model discloses a kind of off-course brake, comprise first matrix and second matrix; Described first matrix and described second matrix include an oil cylinder, a plunger, a Sealing, first friction ring, second friction ring; Described plunger is arranged in the described oil cylinder; Described Sealing, the described first friction ring setting, described second friction ring are separately positioned between described plunger and the described oil cylinder; Described second friction ring and described first friction ring are positioned at the both sides of described Sealing at the axial direction of described plunger; Described first friction ring is different with the thickness on the described axial direction of described second friction ring at described plunger at the thickness on the axial direction of described plunger.By the first different friction ring of thickness and second friction ring are set in the Sealing both sides, first friction ring of different-thickness and second friction ring both can alleviate or eliminate plunger to be damaged to prevent Sealing the radial force that Sealing applies, again escapable cost.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
