Description
Technical field
Shaft coupling technical field is the utility model is related to, specifically a kind of carbon fiber pipe ball cage type Hooks coupling universal coupling.
Background technology
Cooling tower is widely used in the fields such as oil, metallurgy, electric power, steelmaking furnace, steel-making heating furnace, knot in steel industry
Numerous workshop sections such as brilliant device, steel rolling, coking are both needed to apply cooling tower.Current domestic cooling tower fan transmission shaft uses elasticity of import more
Diaphragm type coupler, the drawbacks such as delivery cycle is long, installation requirement is high, eccentric drift angle is small be present.
Such as it is replaced using the mode of common ballcouplinh and mild steel shaft pipe welding, except checking its torsion
Outside intensity, more need to check critical speed of drive shaft, the calculating of power transmission shaft critical speed typically all uses to be introduced on many documents
Power transmission shaft critical Speed Calculation formula：
Nc=1.2×1.08×/L2 ,r/min
In formula, D, the external diameter and internal diameter of d-- central siphons, mm；
The centre-to-centre spacing of the bearing length of L power transmission shafts, i.e. two universal joints；
The actual use maximum speed that critical speed Nc have to be larger than power transmission shaft is calculated, because power transmission shaft is using process
In, once it will cause resonance, middle part amount of deflection and vibrating noise drastically increase, and cause central siphon bending very close to critical speed
To fracture.
And because the general mounting distance of cooling tower fan transmission shaft is all longer（In 4.5m ~ 7m）, therefore improve its critical speed
Method just only increase the outer diameter D of central siphon, but can thus increase the quality and rotary inertia of power transmission shaft, can equally bring matter
Amount problem.Therefore, it is extremely urgent to design a kind of new carbon fiber pipe ball cage type Hooks coupling universal coupling.
The content of the invention
For overcome the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of carbon fiber pipe ball cage type ten thousand
To shaft coupling, to meet that ball cage type Hooks coupling universal coupling is installed over long distances, high, easy for installation, the eccentric drift angle of critical speed is big, work
Needs with small vibration.
For achieving the above object, inner ring one of the present utility model is connected with drive end shaft extension, realizes that power is defeated
Enter, inner ring is connected once steel ball one with outer ring one；Outer ring one is connected by carbon fiber pipe with outer ring two；Outer ring two through steel ball two with
Inner ring two connects, and inner ring two is connected with driven end shaft extension, realizes power output.
Have on the inner ring one and outer ring one it is a plurality of be circumferentially uniformly distributed, cross section is the straight flute road of ellipse, torque
Transmitted through bear inner ring grooved railway, steel ball one, outer ring raceway；Inner stopper one, the flange of carbon fiber pipe are carried on the end face of outer ring one
External diameter and the inner stopper one of outer ring one coordinate, and realize feeling relieved, being spacing for outer ring one and carbon fiber pipe, outer ring one leads to carbon fiber pipe
Cross bolt one, elastic washer one and nut one to connect, realize positioning and reverse and transmit；One end of steel ball one is equipped with lip packing
One, fixed by gland one, other end baffle plate one and hole back-up ring one seal.
Have on the inner ring two and outer ring two it is a plurality of be circumferentially uniformly distributed, cross section is the straight flute road of ellipse, torque
Transmitted through bear inner ring grooved railway, steel ball two, outer ring raceway；Inner stopper two, the flange of carbon fiber pipe are carried on the end face of outer ring two
External diameter and the inner stopper two of outer ring two coordinate, and realize feeling relieved, being spacing for outer ring two and carbon fiber pipe, outer ring two leads to carbon fiber pipe
Cross bolt two, elastic washer two and nut two to connect, realize positioning and reverse and transmit；One end of steel ball two is equipped with lip packing
Two, fixed by gland two, other end baffle plate two and hole back-up ring two seal.
The utility model compared with prior art, has advantages below：
1st, the design feature of synchro-nizing universal coupling with ball and sacker is combined, there is constant-speed transmission, absorb vibration, operate and put down
Surely, the advantages of large carrying capacity；Flexible sheet is replaced to increase power transmission shaft angular compensatory energy as force transfer element using universal joint
Power, significantly reduce mounting and adjusting difficulty；Universal joint is internally formed the lubricating system of closing, can effectively prevent internal lubrication fat
Leakage and introduced contaminants enter inside universal joint, ensure its longtime running, extend power transmission shaft service life.
2nd, jackshaft uses carbon fiber pipe material, and its weight is only the 1/5 of common iron, hence it is evident that alleviates power transmission shaft
Weight, while drive axis inertia is reduced, also improve its critical speed.Carbon fibre material tensile strength is ordinary steel
6 ~ 12 times of material, modulus of elasticity are higher than steel, have excellent creep-resistant property, deform small under long range state, can meet cold
But the applying working condition of tower blower fan power transmission shaft installation distance.
3rd, carbon fiber pipe jackshaft has good durable and corrosion resistance, and it is easy in cooling tower spray to overcome mild steel
The shortcomings that getting rusty, it is non-conductive, it is nonmagnetic, and due in light weight, in blower fan operation process, may also function as the effect of energy-conservation.
4th, carbon fiber pipe jackshaft uses flange and the one-time formed technique of central siphon, avoids in secondary bonding, riveting
Destabilizing factor, and concentricity is high, stability is strong, is felt relieved with cage universal joint outer ring by seam, the mode that bolt is fixed
Connection, easy installation and removal, centering effect is good, and power transmits reliable and stable.
