Abstract
The utility model relates to the field of mechanical equipment, and particularly discloses a hydraulic disassembly extractor for a gear, wherein the hydraulic disassembly extractor for the gear can disassemble the gear conveniently and ensure the completeness of the gear. The hydraulic disassembly extractor for the gear comprises an oil pump, a hydraulic cylinder, a hydraulic oil guide pipe, two semi-circular pulling barrels and a locking ring, wherein the two semi-circular pulling barrels are matched to form a hollow cylinder, through holes are formed in the centers of the two ends of the two semi-circular pulling barrels after the semi-circular pulling barrels are matched, the oil pump and the hydraulic cylinder are connected through the hydraulic oil guide pipe, a telescopic rod is arranged at one end of the hydraulic cylinder, a convex ring is arranged on the outer wall of the hydraulic cylinder, one end of each semi-circular pulling barrel is clamped on the convex ring, and the two semi-circular pulling barrels after being matched are sleeved with the locking ring. The hydraulic disassembly extractor for the gear has the advantages of being simple in structure, convenient to operate and the like.
Description
Technical field
The utility model relates to the plant equipment field, and especially a kind of gear hydraulic unloads and pulls out device.
Background technology
Through operation for a long time, equipment depreciation breaks down very normal, as the problems such as noise is excessive appear in up-coiler pressure roll motor often, need to change the bearing on motor shaft, but must pull down the gear of motor shaft front end before the bearing on the replacing motor shaft, and existing extracting tool has La Ma and ripping bar substantially, while using this two kinds of instrument disengage gears, not only need to spend a large amount of manpowers and time, operating efficiency is low, and easily makes gear teeth edge deformation, causes gear failure, cause the waste of resource, increased production cost.
The utility model content
The purpose of this utility model is the deficiency in order to solve above-mentioned technology and provide a kind of convenient to gear disassembling, and dismounting advances to guarantee that gear hydraulic that gear can not deform unloads pulls out device.
In order to achieve the above object, the designed gear hydraulic of the utility model unloads and pulls out device, and it comprises oil pump, hydraulic cylinder, hydraulic oil conduit, two semicircle slides, locking circle; Form hollow circular cylinder after two semicircle slides coordinate, the center at the two ends of two semicircle slides after cooperation is provided with through hole; Oil pump is connected by the hydraulic oil conduit with hydraulic cylinder, at an end of hydraulic cylinder, is provided with expansion link, on the outer wall of hydraulic cylinder, is provided with flange collar; One end of two semicircle slides is stuck on flange collar, and the outer cover of two semicircle slides after cooperation is provided with the locking circle.
The diameter of extension bar is less than the diameter of split motor shaft; The wherein diameter of the manhole of an end of two semicircle slides is greater than the external diameter of the barrel of hydraulic cylinder, and is less than the external diameter of flange collar, and the diameter of the manhole of the other end of two semicircle slides is greater than the diameter of split motor shaft, and is less than the external diameter of split gear.
For locking circle and two semicircle slides are formed preferably, coordinate, thereby the locking circle is matched in clearance with two semicircle slides.
As optimization, in order to reduce use cost, reduce energy resource consumption, the employing oil pump is hand oil pump.
The resulting gear hydraulic of the utility model unloads and pulls out device, it is simple in structure, low production cost, in use, only two semicircle slides need be enveloped to split gear, and an end of two semicircle slides is stuck on flange collar, expansion link stretches out to contact with split motor shaft to obtain and supports, again under the effect of oil pump, the outwardly directed while of expansion link can pull down split gear, time saving and energy saving, and to the distribution of forces of split gear on whole ring surface, can guarantee that split gear is indeformable, do not damage, simultaneously because the oil pressure of needs is less, can adopt hand oil pump, thereby reduction use cost, reduce energy consumption, further reduce costs.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, the gear hydraulic that the present embodiment is described unloads and pulls out device, it comprises oil pump 1 and hydraulic cylinder 2, oil pump 1 is connected by hydraulic oil conduit 8 with hydraulic cylinder 2, front end at hydraulic cylinder 2 is provided with expansion link 3, be provided with flange collar 5 on the outer wall of the front end of hydraulic cylinder 2, after coordinating, two semicircle slides form hollow circular cylinder, the center at the two ends of two semicircle slides 4 after cooperation is provided with manhole 6, the outer cover of two semicircle slides 4 after cooperation is provided with locking circle 7, and the diameter of extension bar 3 is less than the diameter of split motor shaft 9; The diameter of the manhole 6 of a wherein end of two semicircle slides 4 is greater than the external diameter of the barrel of hydraulic cylinder 2, and is less than the external diameter of flange collar 5; The diameter of the manhole 6 of the other end of two semicircle slides 4 is greater than the diameter of split motor shaft 9, and is less than the external diameter of split gear 10.
