Abstract
The utility model provides a novel device for quickly replacing an oil seal and relates to the field of engineering machinery. A vibrating shaft (12) is arranged in a flange plate (8); a check ring (10) is clung to the vibrating shaft (12); a frame oil seal (9) is arranged in the flange plate (8) and is fixed with the check ring (10); a bearing (11) is placed into the flange plate (8), is clung to the frame oil seal (9) and is fixed with the check ring (10); a coupler gear (7) is fixedly arranged on the vibrating shaft (12); a circular pressing plate (3) is arranged in the space of the flange plate (8) and the coupler gear (7); an outer edge of the coupler gear (7) is locked by a step of the circular pressing plate (3); a nut pin (4) is connected with a nut (1) and a gasket (2) in turn; a jacking pull screw rod (5) is resisted against a central hole at an axial end of the vibrating shaft (12); and a wrench (6) is sleeved on the jacking pull screw rod (5). The novel device for quickly replacing the oil seal has the advantages of simple structure, convenience in mounting and dismounting, and capability of greatly saving the time for replacing the oil seal.
Description
Technical field
The utility model relates to engineering machinery field, is specifically related to a kind of device of novel quick replacing oil sealing.
Background technology
The outside framework oil seal of the vibrating shaft of engineering machinery damages and must in time change; Otherwise can cause the oil leak in the chamber; More likely burn out phenomenons such as vibration bearing, and must remove the shaft coupling gear of vibrating shaft when changing the outside framework oil seal of vibrating shaft earlier, this is because the shaft coupling gear cooperates with vibrating shaft is interference fit; And the real space in the ring flange is less, so cause very difficulty of dismounting shaft coupling gear.
Summary of the invention
The purpose of the utility model provides a kind of device of novel quick replacing oil sealing, and it can solve existing problem in the background technology effectively.
In order to solve the existing problem of background technology, the utility model adopts following technical scheme: it comprises nut 1, packing ring 2, semicircle pressing plate 3, nut pin 4, pulls screw rod 5, spanner 6, shaft coupling gear 7, ring flange 8, outside framework oil seal 9, back-up ring 10, bearing 11 and vibrating shaft 12; Vibrating shaft 12 is arranged in the ring flange 8, and back-up ring 10 is close on the vibrating shaft 12, and outside framework oil seal 9 is arranged in the ring flange 8; And fix with back-up ring 10; Bearing 11 is put into ring flange 8 and outside framework oil seal 9 applyings and fixing with back-up ring 10, and shaft coupling gear 7 is fixed on the vibrating shaft 12, and circular pressing plate 3 is arranged in the space of ring flange 8 and shaft coupling gear 7; The step of semicircle pressing plate 3 blocks the outer rim of shaft coupling gear 7; Nut pin 4 is linked in sequence with nut 1, packing ring 2, pulls the centre bore that screw rod 5 withstands on vibrating shaft 12 axle heads, and spanner 6 is enclosed within pulls on the screw rod 5.
The utlity model has following beneficial effect: simple in structure, installing/dismounting is very convenient, has practiced thrift the time of the envelope of changing oil greatly.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment is to adopt following technical scheme: it comprises nut 1, packing ring 2, semicircle pressing plate 3, nut pin 4, pulls screw rod 5, spanner 6, shaft coupling gear 7, ring flange 8, outside framework oil seal 9, back-up ring 10, bearing 11 and vibrating shaft 12; Vibrating shaft 12 is arranged in the ring flange 8, and back-up ring 10 is close on the vibrating shaft 12, and outside framework oil seal 9 is arranged in the ring flange 8; And fix with back-up ring 10; Bearing 11 is put into ring flange 8 and outside framework oil seal 9 applyings and fixing with back-up ring 10, and shaft coupling gear 7 is fixed on the vibrating shaft 12, and circular pressing plate 3 is arranged in the space of ring flange 8 and shaft coupling gear 7; The step of semicircle pressing plate 3 blocks the outer rim of shaft coupling gear 7; Nut pin 4 is linked in sequence with nut 1, packing ring 2, pulls the centre bore that screw rod 5 withstands on vibrating shaft 12 axle heads, and spanner 6 is enclosed within pulls on the screw rod 5.
Earlier semicircle pressing plate 3 is put into the space of ring flange 8, and make its step block shaft coupling gear 7, put on nut pin 4 then successively; Nut 1, packing ring 2 screw on and pull screw rod 5 and make it withstand vibrating shaft 12 axle head centre bores, turn clockwise with spanner at last and pull screw rod 5; Make and pull screw rod 5 and move equably; Until extracting shaft coupling gear 7, dismantle bearing 11 again, the outside framework oil seal 9 in the replacing.
This specific embodiment has following beneficial effect: simple in structure, installing/dismounting is very convenient, has practiced thrift the time of the envelope of changing oil greatly.
