Abstract
The utility model discloses a transmission shaft tensioner, which comprises a positioning disk, wherein a centering hole is formed in the middle part of the positioning disk; fixing holes which are distributed along the circumferential direction around the centering hole are formed in the positioning disk; a pressing mechanism is arranged in the centering hole of the positioning disk; a positioning ball is arranged at the front end of the pressing mechanism. The transmission shaft tensioner has the advantages of simple structure, small size, light weight, no need of detaching transmission equipment, and easiness and convenience in operation; the pressing mechanism is in surface contact with the end face of a transmission shaft, so that the transmission shaft is stressed uniformly without causing damages to the shaft end face, the overhauling time of equipment can be shortened greatly, the labor capacity of workers is reduced, the labor intensity of workers can be lowered greatly, and the working efficiency of overhauling personnel can be increased greatly. The positioning disk is not less than 30 millimeters in thickness, and has high structural strength, so that deformation of the positioning disk under excessive external force can be prevented effectively. The fixing holes are radial long adjusting holes, and eight radial long adjusting holes are uniformly distributed in the positioning disk in order to adapt to the hole distances among connecting bolts on the end faces of transmission shafts of different specifications, so that the application range is wide, and the equipment investment is saved.
Description
Technical field
The utility model belongs to drive apparatus service kit technical field, particularly a kind of power transmission shaft chest expander.
Background technology
All used drive apparatus in fields such as oil, chemical industry, power plant, for example motor and pump, all include power transmission shaft in drive apparatus.But, power transmission shaft in use easily damages, after damage, need to overhaul, traditional repair method is: first the dismounting coupling between power transmission shaft and power transmission shaft is got off, due to the distance between prime mover and driven machine and space narrower and small, the distance that only has shaft coupling to grow so, traditional service kit cannot be in so narrow space use, sometimes also need prime mover or driven machine to disassemble from installation site, could use other chest expander that power transmission shaft is disassembled and overhaul or change (generally using tri-paw puller), and discontinuity.Increased workload so just to use and the maintenance of drive apparatus, and working strength is large, the waste plenty of time, particularly some comparison in equipment heaviness, more difficult in unloading process, waste time and energy, inefficiency.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy and simple to handle and power transmission shaft chest expander that operating efficiency is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of power transmission shaft chest expander, comprise that middle part is provided with the positioning disk of internal point, and positioning disk is provided with the fixing hole circumferentially distributing around internal point; In the internal point of described positioning disk, be provided with top-pressure mechanism, top-pressure mechanism front end is provided with place kick.
Described top-pressure mechanism comprises top pressure screw rod and the retaining thread piece of threaded engagement, and retaining thread piece is fixed on positioning disk, and top presses screw rod to be located in internal point; Place kick is fixed on top and presses in the middle part of the front end face of screw rod.
Described top-pressure mechanism is hydraulic jack, and the piston rod of hydraulic jack is located in internal point; Place kick is fixed on the front end face middle part of piston rod.
The thickness of described positioning disk is not less than 30mm.
Described fixing hole is elongated adjustment hole radially, and its number is eight, eight radially elongated adjustment hole be distributed on positioning disk.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model comprises that middle part is provided with the positioning disk of internal point, and positioning disk is provided with the fixing hole circumferentially distributing around internal point; In the internal point of described positioning disk, be provided with top-pressure mechanism, top-pressure mechanism front end is provided with place kick, and it is simple in structure, volume is little, lightweight, without dismounting drive apparatus, easy and simple to handle, between top-pressure mechanism and transmission shaft end surface, be plane-plane contact, stressed transmission shaft is even, can not cause the damage of axial end to wheel, and can greatly shorten the overhaul of the equipments time, reduce workman's amount of labour, reduce labor strength, can greatly improve maintainer's operating efficiency.
2, the thickness of positioning disk is not less than 30mm, and structural strength is large, can effectively prevent the distortion that positioning disk causes under the excessive situation of external force.
3, fixing hole is elongated adjustment hole radially, eight radially elongated adjustment hole be distributed on positioning disk, can adapt to the transmission shaft end surface connecting bolt pitch-row of different size, range of application is wide, saves equipment investment.

Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the side view of positioning disk in Fig. 1;
Fig. 3 is the use view of the utility model embodiment 1;
Fig. 4 is the structural representation of the utility model embodiment 2.
Detailed description of the invention
Embodiment 1, power transmission shaft chest expander as depicted in figs. 1 and 2, it comprises positioning disk 1, be provided with circular internal point 3 at the middle part of positioning disk 1, positioning disk 1 is provided with eight fixing holes 2 that circumferentially distribute around internal point 3, and fixing hole 2 is elongated adjustment hole radially, eight radially elongated adjustment hole be distributed on positioning disk 1.Fixing hole 2 is elongated adjustment hole radially, can adapt to the transmission shaft end surface connecting bolt pitch-row of different size, and range of application is wide, saves equipment investment.In the internal point 3 of positioning disk 1, be provided with top-pressure mechanism, described top-pressure mechanism comprises top pressure screw rod 5 and the retaining thread piece 4 of threaded engagement, and retaining thread piece 4 is weldingly fixed on positioning disk 1 right side, and corresponding with internal point 3, and top presses screw rod 5 to be located in internal point 3; Sweat and have place kick 6 at the front end face middle part of top pressure screw rod 5, place kick 6 is for the axle head center of locating transmission axle.
In the present embodiment, the thickness of positioning disk 1 is not less than 30mm, with the distortion that prevents that positioning disk 1 from causing under the excessive situation of external force.
Fig. 3 is use schematic diagram of the present utility model, and use procedure is: first, pull down device coupling; Then, utilize and connect axial end that the bolt 11 of shaft coupling is installed to positioning disk 1 power transmission shaft 9 to taking turns on 10, adjust place kick 6, it is aimed at the center of power transmission shaft 9, fastening bolt 11 again after centralized positioning; Finally, slowly rotate top press screw rod 5 with spanner, make it slowly to push up and press power transmission shaft 9, under the pressure effect of top, power transmission shaft 9 and axial end can slowly be removed to taking turns 10.Above-mentioned whole process only needs a maintainer and a spanner, easy and simple to handle.
