Description
Technical field
The present invention relates to field of mechanical technique, be specifically related to crown gear coupling.
Background technique
The feature (having following characteristics compared with spur type coupling) 1 of drum-shaped tooth type shaft coupling, bearing capacity are strong.Under identical internal tooth casing external diameter and coupling maximum outside diameter, the bearing capacity average specific spur type coupling of drum-shaped tooth type shaft coupling improves 15 ~ 20%; 2, angular displacement compensation rate is large.When radial displacement equals zero, the angular displacement allowable of spur type coupling is 1 °, and the angular displacement allowable of drum-shaped tooth type shaft coupling is 1 ° 30 ", improve 50%, under identical modulus, the number of teeth, the facewidth, the angular displacement that crowned teeth allows than straight-tooth is large; 3, drum-shaped tooth makes the contact conditions of inside and outside tooth improve, and avoid the drawback that the extruding of straight-tooth increment seamed edge, stress are concentrated under angular displacement condition, improve gear tooth friction, wear condition simultaneously, reduce noise, service cycle is long; 4, external tooth cover increment flare shape, makes inside and outside tooth install and remove very convenient.5, transmission efficiency is up to 99.7%.Based on above feature, general substitute spur type coupling with crowned teeth both at home and abroad.The drum-shaped tooth type shaft coupling description that UMA produces is complete, and meets corresponding standard.Drum-shaped tooth type shaft coupling, its rigidity is large, has flexibility, nonelastic, therefore is not suitable for for requiring the machinery that vibration damping, buffering and two shaft assignment requirements are strict.
Drum type gear coupling can self adaption, the self-tuning technology, the particularly distributed high-end drum-shaped tooth type shaft coupling with communication, network savvy and integrated PLC of compensating load change; On the other hand simple or the special drum-shaped tooth type shaft coupling of industry and electromechanical integration, miniaturization drum-shaped tooth type shaft coupling.Drum-shaped tooth type shaft coupling is the key equipment of energy saving.According to network media statistics, current domestic band fluctuating load, the motor with energy-saving potential has 1.8 hundred million kilowatts at least, thus for the application of drum-shaped tooth type shaft coupling provides very huge market.The application of drum type gear coupling is extended to food, beverage, logistics, building etc. by common blower fan, water pump etc., continuous open new energy-saving field, its function also gets a promotion and variation, total digitalization on the one hand, multiple functional, in addition, due to the appearance of novel high-pressure power electronic device, high and medium voltage drum-shaped tooth type shaft coupling also has significant progress.
The angular displacement of the crown gear coupling of prior art strengthens, and whole link rod downwarp is strengthened, and the centrifugal force rotating generation also increases, and makes bolt bear excessive tensile stress, thus easily makes bolt fracture workpiece cisco unity malfunction.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, the crown gear coupling that a kind of structure is simple, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution used in the present invention is: it comprises rigid catcher, interior gear cover, Compress Spring, external tooth inner sleeve, bolt hole, Fixing shrink ring, connecting bolt; Described interior gear cover is coordinated by tooth with external tooth inner sleeve, and interior gear cover is set in one end outer wall of external tooth inner sleeve; Compress Spring is provided with in the left end groove of described external tooth inner sleeve, one end of Compress Spring is set on rigid catcher, one end of rigid catcher is connected by fastening piece with the left end endoporus of interior gear cover, and the other end of rigid catcher is plugged in the left end groove of external tooth inner sleeve; The outer wall of described interior gear cover is provided with Fixing shrink ring, and puts in Fixing shrink ring and external tooth and be provided with bolt hole, and interior gear cover is connected by several connecting bolt with external tooth inner sleeve.
As preferably, described connecting bolt is M16 ~ M30 bolt.
As preferably, described interior gear cover is connected by two connecting bolts with external tooth inner sleeve.
As preferably, described connecting bolt is 12.9 grade high-strength bolts.
When the present invention operates, it is consistent for installing speed reducer each output shaft axle center with production machine bridge joint hand axle center due to equipment, there is the frame shaft axis bias error of alignment error and production process mid frame wearing and tearing generation, interior gear cover and external tooth inner sleeve are coordinated by tooth and connect, thus decrease the angular displacement of this part.
After adopting said structure, the beneficial effect that the present invention produces is: crown gear coupling of the present invention, decrease the angular displacement of coupling, decrease link rod downwarp, thus centrifugal force when also reducing link rod running, enhance the stability of link rod, the present invention have structure simple, arrange rationally, the advantage such as fabricating cost is low.
