Abstract
The utility model relates to a torque-eliminating spiral cradle roll, composed of a bracket, a spiral roll system, a flexible axle system, a torque-eliminating joint, and a bearing seat. The utility model has automatic aligning ability, shock resistance ability, and big load-carrying ability. Because the spiral doesn't bear the loading, having no torsion and torque force, it can not cause elastic and torsional fatigue, and the corresponding shape change can not be caused, either. The spiral parameter can not change as the change of the width of the belt; the application range is wide; the service life is long; the self weight is light; the utility model can simplify the structure of the belt conveyer, and the weight and the horsepower can be reduced. The utility model is saving in energy and material, simple in construction technology, easy in use and maintenance, and convenient in common popularization and use.
Description
The utility model relates to a kind of travelling belt carrying roller.
Chinese patent 91220621.7 auto-centering carrying rollers, though solved preferably make belt not sideslip, do not job-hop, problem such as auto-centering, but because spring performance contradicts with the carrying roller job specification, should bear whole load by spring, reverse and draw, work under the torque condition at high frequency for a long time again, spring fatiguability and produce distortion not only exists power and power consumption that spring failure, fracture and belt fall the hidden danger of groove and increase and increased belt transporter.Simultaneously, owing to be by elasticity and elastic force work, along with the variation of belt width and load, spring parameter also needs to change thereupon, and material is strict, the manufacturing process complexity, and consumptive material is many, from great, restricted application.
Chinese patent 93233545.4 flexible auger carrying rollers, though on the basis of the technological characteristics that has kept the auto-centering carrying roller, fundamentally solved the problem that spring bearing load and construction parameter change, but,, spiral is out of shape and the torsional fatigue problem so still existing screw twisted because spiral still exists and reverses and twisting force.
The purpose of this utility model is to overcome weak point above-mentioned in the background technology, and provide a kind of and operate steadily, not sideslip, do not job-hop, helix parameter does not need to change with belt width and load variations, spiral is not reversed and torsion, and is shock-resistant, and load capacity is big, applied widely, long service life, structural manufacturing process is simple, uses maintenance easy, saving metal material and energy, simplify the structure of belt transportation greatly, reduce its weight and power, the spiral carrying roller is turned round in disappearing that cost is low.
The purpose of this utility model realizes by following approach: bearing seat by stent support, bearing seat is installed tapered roller bearing and the ball bearing of main shaft with the hollow shaft suit, and hollow shaft one end is connected with spiral base, and spiral base and propellers are solidly fixed.Tapered roller bearing and ball bearing of main shaft are separated by spacer.The flexible axle that passes hollow shaft is supported on by fulcrum and encircles in the tapered roller bearing on the end face, connects the twist joint that disappears between the two joint propellers.
Of the present utility model disappearing turned round the spiral carrying roller, the twist joint that disappears comprises the plinth of connecting bolt roller, on have the sheath that is sleeved on flexible axle middle part of groove, sheath is connected with two plinths with backing pin on being contained in the plinth end face by the pin that radially inserts in the groove, in the groove of sheath positive stop is housed, suit plays the lock tube of locking action on the plinth to pin.
Of the present utility model disappearing turned round the spiral carrying roller, and the twist joint that disappears can be one or more, and propellers also can be two joint or more pieces.
The utility model is compared background technology following advantage: spiral does not bear load, does not reverse and twisting force, can not produce elasticity and reverse tired and distortion, have shock-resistantly, load capacity is big, and is applied widely, long service life, structural manufacturing process is simple, and working service is easy, from heavy and light, energy-saving material-saving, cost are low, and can simplify the structure of belt transportation, and reduce its weight and power, be convenient to generally promote the use of.
The embodiment of the utility model in conjunction with the accompanying drawings is described in further detail.
Fig. 1 disappears and turns round spiral carrying roller scheme drawing (Figure of abstract)
Fig. 2 disappears and turns round the local enlarged diagram of spiral carrying roller F
Fig. 3 disappears and turns round spiral carrying roller ABCDEA cutaway view
As shown in Figure 1, of the present utility model disappearing turned round the spiral carrying roller, support 1 supporting bearing base 2, and the tapered roller bearing 4 and the ball bearing of main shaft 6 of installation and hollow shaft 7 suits in the bearing seat 2, tapered roller bearing 4 and ball bearing of main shaft 6 are separated by spacer 5.Hollow shaft 7 other ends are connected with spiral base 8, and spiral base 8 is solidly fixed with propellers 9, place the flexible axle 10 of propellers 9 inner chambers to pass hollow shaft 7 and are supported in the tapered roller bearing 4 on the ring end faces by fulcrum 3, connect the twist joint that disappears between two joint propellers 9.
As Fig. 2, shown in Figure 3, of the present utility model disappearing turned round the spiral carrying roller, the twist joint that disappears comprises the plinth 15 of connecting bolt roller 9, on have a groove sheath 11 be sleeved on flexible axle 10 middle parts, sheath 11 is connected with two plinths 15 with backing pin 13 on being contained in plinth 15 end faces by the pin 12 that radially inserts in the groove.In sheath 11 grooves positive stop 16 is housed.Suit is to the lock tube 14 of 12 locking actions of pin on plinth 15.Two plinths 15 can only relatively rotate a corner less than 180 degree in the effect of positive stop 16, have both guaranteed between two joint (or more piece) screw shafts 9 and the synchronous rotation between propellers 9 and the flexible axle 10, can avoid flexible axle 10 to be distorted again.
