Description
Technical field
The utility model relates to the assembling manufacture field of rotational workpieces, specifically is a kind of rotor field spider of large-scale slewing.
Background technology
Rotor field spider is the rotor corollary equipment in the large-scale slewing, is widely used in the placement, blade assembling, rotor processing of rotor class rotary parts such as steam turbine, nuclear power, combustion machine, wind-powered electricity generation etc., rotor is risen support and turning effort.Rotor field spider divides manually and electronic two kinds, is the packaged type portable equipment, pulls workpiece by manual work when type hand uses and forms gyration; Power type is realized the support roller rotation and then drives workpiece rotational motion that by the hand-held control box control of operation motor it is arbitrarily angled that infinitely variable speeds can be controlled rotor rotation; The spacing of roller of matching in addition can be regulated, and realizes the rotor workpiece support of various axle journals sizes.Placement after the fine finishining of rotor workpiece, blade assembling and checking etc. all need be used rolling wheel support, in order to avoid rotor sustains damage.
As shown in Figure 1, rotor field spider is made up of support roller 2 and bracing frame 3 two parts, and support roller 2 directly contacts with the axle journal of rotor workpiece 1 in the rotor field spider, so the performance of the structure of support roller 2 directly has influence on the rotor journal precision.
Support roller 2 is used very extensive on market, and particularly utilization is particularly outstanding on the turning rolls.At present, though support roller 2 main integral casting ironware and two kinds of forms of copper casting (or copper sheathing spare) of adopting are support roller 2 low prices of ironcasting; But get rusty easily; Service life is short, the more important thing is that the axle journal position to rotor workpiece 1 is prone to constitute injury, is not suitable for the support of rotor workpiece 1; Though the support roller 2 of copper casting has good serviceability, the collar potential energy to rotor workpiece 1 forms protection to a certain extent, and copper costs an arm and a leg, and cost is higher, and quality is also big.
The rotor field spider that has adopts common MC nylon protective sleeve in the outer ring of metal roller, along with steam turbine power generation unit power strengthens, and the increase of rotor weight, the roller protective sleeve can not take the weight fragile; Casting MC composite nylon is adopted in the roller outer ring, and tensile strength is high, but there is defective in casting rear-wheel hub contact position, and the outer ring was loosening easily after roller used a period of time, caused skidding; MC composite nylon interference fit wheel hub is adopted in the roller outer ring, and installing and locating pin on circumference is because composite nylon interference assembling; There is stress in the outer ring, is prone to during punching break, and promptly enables to install alignment pin; Under the pressure of heavy rotor, the outer ring also is prone to damage from rationed marketing.
Summary of the invention
The purpose of the utility model is: the rotor field spider that a kind of durable in use, safe and reliable large-scale slewing is provided.
The technical scheme that the utility model adopted is:
A kind of rotor field spider of large-scale slewing; Constitute by bracing frame and a pair of support roller that is arranged on the bracing frame top; Said support roller comprises the metal core wheel and is enclosed within the nylon protective sleeve on the metal core wheel outer ring; The contact-making surface end of metal core wheel and nylon protective sleeve is fixed with the axle head baffle plate of nylon protective sleeve through screw, and the outer ring of this axle head baffle plate is the inner ring setting of spline-like, corresponding nylon protective sleeve, and the outer ring of the corresponding metal core wheel of interior ring of axle head baffle plate is provided with.
The axle head baffle plate of corresponding spline-like, the inner ring end that the end, outer ring of metal core wheel is provided with cannelure, nylon protective sleeve is provided with keyway, and behind keyway cooperation and the installation shaft end-stopping plate, the side of support roller is a horizontal plane.
Said axle head baffle plate is connected on the outer ring of metal core wheel through screw.
The spline of said axle head baffle plate is provided with symmetrically and evenly.
Said metal core wheel and nylon protective sleeve adopt the radial interference fit assembling.
Said rolling wheel support is divided into active roller support and return idler support, both supporting uses.
The beneficial effect that the utility model produced is:
The support roller of the rotor field spider of the large-scale slewing of the utility model can take the weight easy, not fragile effectively, and outer ring protective sleeve tensile strength is high, it is loosening to be difficult for, can not skidding; MC composite nylon interference fit wheel hub is adopted in the roller outer ring, and the axle head baffle plate through particular design forms axial location and radial location to nylon jacket, makes that MC nylon jacket and wheel hub are peeled off, axial float obtains limiting, even under heavy duty, also can not be subjected to displacement.
The roller of said structure has following advantage:
1) the MC composite nylon material is adopted in the roller outer ring, effectively protects rotor journal.The MC composite nylon has higher tensile strength at normal temperatures; Good impact flexibility, oil resistivity, immersion resistance, hardness and fatigue strength, special wearability and self-lubricating property are excellent, and coefficient of friction is little; Ability weak acid resistant alkali and common solvent; Itself do not have smell, tasteless, nontoxic, do not go rotten, can use below the C at 80 °, non-ferrous metals such as Alloy instead of Copper, chromium and babbit are made various machine parts.
2) the overcoat baffle plate adopts the projective table type structure, promptly has the axial location function that the radial location function is arranged again.
3) overcoat adopts interference fit, and is easy to assembly.
At present, the rotor field spider of this roller structure can be widely applied on rolling wheel support, and range of application does not wait at 10T, 30T, 50T, 60T, 100T, 120T, 200T, 300 T, is suitable for large-scale production and use.
