Abstract
The utility model discloses a quickly replaced framework oil seal device, composed of a nut, a cushion ring, a semi-circular press plate, a nut pin, a pushing and pulling threaded rod, a spanner, a shaft coupling gear, a flange disk, a framework oil seal, a check ring, bearings and a vibrating shaft. The step of one end of the semi-circular press plate clamps the shaft coupling gear, the opening on the other end is connected with the nut pin and is provided with the nut and the cushion ring, the middle of the nut pin is provided with the pushing and pulling threaded rod, one end of which is provided with the spanner, and the other end pushes the vibrating shaft. The spanner is rotated to make the pushing and pulling threaded rod uniformly move, the shaft coupling gear is pulled down, and the bearings are dismounted, and then the framework oil seal of the damaged vibrating shaft is replaced. The quickly replaced framework oil seal has the characteristics of quick replacement of the framework oil seal of the damaged vibrating shaft, convenient operation, simple structure, convenient maintenance, wide application scope, etc.
Description
Must in time change used novel quick replacing outside framework oil seal device after the outside framework oil seal that technical field the utility model relates to the vibrating shaft that type such as a kind of horizontal directional drilling machine uses damages, be adapted to other machinery of the outside framework oil seal that replacing in time damaged especially.
Background technology is present, after the outside framework oil seal of the vibrating shaft of the machinery of types such as horizontal directional drilling machine damages, run into a realistic problem, be exactly in time to change outside framework oil seal, otherwise will cause the oil leakage in the chamber, more likely burn out accidents such as vibration bearing, when changing the outside framework oil seal of vibrating shaft, must remove the shaft coupling gear of vibrating shaft earlier.Be interference fit because the shaft coupling gear cooperates with vibrating shaft, and the real space in the ring flange is less, so cause dismounting shaft coupling gear very difficult.
The summary of the invention the purpose of this utility model provides the novel quick replacing outside framework oil seal device of a kind of simple in structure, use, operation, special use easy for installation.
The purpose of this utility model be achieved in that this novel quick replacing outside framework oil seal device by nut, packing ring, semicircle pressing plate, nut pin, pull screw rod, spanner, shaft coupling gear, ring flange, outside framework oil seal, back-up ring, bearing, vibrating shaft and form.The step of one end of semicircle pressing plate blocks the shaft coupling gear, perforate on the other end links to each other with nut pin, install nut, packing ring again, install in the middle of nut pin and pull screw rod, pull an end assembly wrench of screw rod, the other end withstands vibrating shaft, rotating spanner makes pulls screw rod and moves equably, pull out the shaft coupling gear, the dismounting bearing is changed the outside framework oil seal that has damaged.Described semicircle pressing plate forms by severing certain spacing in the middle of the cylinder, and two is semi-independent.In the middle of each side of half perforate is arranged, the cross section, top is for being semi-round ring shape, and lower section is the semi-round ring shape bigger than top cross section.
Described nut pin is that two ends have screw thread, and the middle part is a cuboid, has screwed hole in the middle of the cuboid.
The described screw rod of pulling is for circular.One end is the quadrangle body, and the other end is a bullet.
When the utility model is installed, at first semicircle pressing plate is fixed in the middle of shaft coupling gear and the ring flange, one end of semicircle pressing plate is blocked the shaft coupling gear, the other end with nut, packing ring, nut pin, pull screw rod and link to each other, spanner is placed on pulls on the screw rod, installation is very convenient with maintenance, and can repeatedly often use.
Be described further below in conjunction with drawings and Examples.
Description of drawings Fig. 1 is an example structure sketch of the present utility model.
Fig. 2 is the cutaway view of the A-A of Fig. 1.
Among the figure: 1. nut; 2. packing ring; 3. semicircle pressing plate; 4. nut pin; 5. pull screw rod; 6. spanner; 7. shaft coupling gear; 8. ring flange; 9. outside framework oil seal; 10. back-up ring; 11. bearing; 12. vibrating shaft;
The specific embodiment is placed on vibrating shaft (12) in the ring flange (8), back-up ring (10) is close on the vibrating shaft (12), outside framework oil seal (9) is put into ring flange (8) and fix with back-up ring (10), bearing (11) is put into ring flange (8) and outside framework oil seal (9) be close to merge with back-up ring (10) and fix, shaft coupling gear (7) is fixed on the vibrating shaft (12).When changing outside framework oil seal (9), semicircle pressing plate (3) is at first put into the space of ring flange (8) and shaft coupling gear (7), allow the step of semicircle pressing plate (3) block the outer rim of shaft coupling gear (7), install nut pin (4) and nut (1), packing ring (2), withstand the centre bore of vibrating shaft (12) axle head with pulling screw rod (5), pull screw rod (5) with spanner (6) rotation, make and pull screw rod (5) and move, after extracting shaft coupling gear (7), the bearing (11) of dismantling, more change the outside framework oil seal (9) of damage, dismounting is very convenient.By above installation, finish present embodiment.
The course of work of the present utility model is: when novel quick replacing outside framework oil seal device is worked, at first semicircle pressing plate is put into the space of ring flange, and make its semicircle pressing plate step block the shaft coupling gear, and put on nut pin then, load onto nut, packing ring, screw on and pull screw rod and make it withstand vibrating shaft axle head centre bore, turn clockwise with spanner at last and pull screw rod, make and pull screw rod and move equably, until extracting the shaft coupling gear, dismantle bearing again, change first-class outside framework oil seal at last.Thereby finish the course of work of novel quick replacing outside framework oil seal device.
