A kind of idler assembly 100 for being adapted to fragile material conveying that the present embodiment provides, including two roller seats 10, one 20 and one hollow roll body 30 of roller carrier shaft.Roller carrier shaft 20 is arranged on roller seat 10 and supported by roller seat 10, and roller carrier shaft 20 includes It is located at two connecting portions 21 of the end of roller carrier shaft 20 and the installation portion 22 being connected between two connecting portions 21, two carrying rollers respectively Seat 10 corresponds respectively with two connecting portions 21；Hollow roll body 30 is rotatably sleeved on installation portion 22, hollow roll body 30 At least two clutch shaft bearings 40 are provided between installation portion 22, second is provided between each connecting portion 21 and each roller seat 10 Bearing 50.
Above-mentioned idler assembly 100, first axle is set using between hollow roll body 30 and the installation portion 22 of roller carrier shaft 20 40 are held, and second bearing 50 is set between the connecting portion 21 and roller seat 10 of roller carrier shaft 20, in such manner, it is possible in hollow roll body 30 Or roller carrier shaft 20, because of bearing damage and during rotation stop, roller carrier shaft 20 or hollow roll body 30 continue to keep rotating, therefore, the idler assembly 100 have the more long life compared to conventional idler, reduce the frequent inspection of attendant and change carrying roller number, while reduce because of support The belt conveyor that roller maintenance occurs shuts down frequency, improves production efficiency.
Referring to Fig. 1, idler assembly 100 includes roller seat 10, roller carrier shaft 20 and hollow roll body 30, and roller seat 10 is supporting Roller carrier shaft 20 and hollow roll body 30.Roller carrier shaft 20, generally cylindrical multi-diameter shaft, its can be solid, part it is hollow or in Hollow structure, the both ends of roller carrier shaft 20 are articulated with roller seat 10 so that roller carrier shaft 20 can rotate around the axis of roller carrier shaft 20.Hollow roll body 30, be circular tubulose substantially in cross section, hollow roll body 30 is rotatably sleeved on roller carrier shaft 20, and hollow roll body 30 with The almost coaxial of roller carrier shaft 20.In the present embodiment, the quantity of roller seat 10 be but be not limited to two (certainly, two roller seats 10 can also be a single piece), hollow roll body 30 is installed in rotation on the outside of installation portion 22 of roller carrier shaft 20, positioned at carrying roller The connecting portion 21 at the both ends of axle 20 is extended to outside the outer end of hollow roll body 30, and connecting portion 21 is installed on corresponding roller seat 10. Clutch shaft bearing 40 is provided between the installation portion 22 of hollow roll body 30 and roller carrier shaft 20, the quantity of clutch shaft bearing 40 is but do not limited to In two, respectively it is connected to the left side clutch shaft bearing 40 (left side in diagram) of the hollow left end of roll body 30 and is connected to hollow roller The right side clutch shaft bearing 40 (right side in diagram) of the right-hand member of body 30, the inner ring of clutch shaft bearing 40 are set in the periphery of installation portion 22 Face, the outer ring of clutch shaft bearing 40 are installed in the annular inner wall of hollow roller；The roller seat 10 of each connecting portion 21 and roller seat 10 Between be provided with a second bearing 50, be respectively connected to the (left side in diagram of left side second bearing 50 of the left end of roller carrier shaft 20 Side) and the right side second bearing 50 (right side in diagram) of the right-hand member of roller carrier shaft 20 is connected to, the inner ring of second bearing 50 is set in The outer peripheral face of connecting portion 21, the outer ring of second bearing 50 are installed in roller seat 10, above-mentioned clutch shaft bearing 40 and second bearing 50 be deep groove ball bearing (it is of course also possible to being cylinder roller bearing), it is worth mentioning at this point that, in each insertion in the hollow both ends of roll body 30 One clutch shaft bearing 40, both ends roller seat 10 respectively have a second bearing 50, and roll body and roller seat 10 are connected by roller carrier shaft 20, Hollow roll body 30 rolls under the effect of belt conveyor frictional force, and during any bearing damage, hollow carrying roller can still follow conveying skin Band rolls, and jam phenomenon will not occurs because of one of bearing damage；Only damaged at least one clutch shaft bearing 40, meanwhile, When at least one second bearing 50 is damaged, jam phenomenon just occurs in idler assembly 100, influences Transmission system normal operation.
Referring to Fig. 1, clutch shaft bearing 40 is arranged on the end of hollow roll body 30, in the present embodiment, outside clutch shaft bearing 40 The end face of end face and hollow roll body 30, projection is formed with for limiting clutch shaft bearing 40 in axial direction on the hollow inwall of roll body 30 The limiting section 31 that upper opposite hollow roll body 30 moves, the internal diameter of limiting section 31 is less than the external diameter of clutch shaft bearing 40, so, first After bearing 40 is assembled in hollow roll body 30, due to the effect of the limiting section 31 in hollow roll body 30, clutch shaft bearing 40 is hollow Position relative securement on the axial direction of roll body 30, and the end face of the outer face of clutch shaft bearing 40 and hollow roll body 30, it is easy to the The installation and dismounting of one bearing 40, are advantageous to the maintenance to clutch shaft bearing 40.
As further optimizing, elastic supporting piece (not shown) is provided between clutch shaft bearing 40 and hollow roll body 30, Elastic supporting piece can be elastomer or elastomeric material, can by be molded or vulcanize glued mode and clutch shaft bearing 40 and/or in Empty roll body 30 is directly connected to, and so, by setting elastic supporting piece, can be weakened and be vibrated caused by hollow roll body 30, reduction is made an uproar Sound.
As further optimizing, the both ends of hollow roll body 30 are connected to axial end cap (not shown), axial end cap The through hole passed with the connecting portion 21 for roller carrier shaft 20, axial end cap pass through the fasteners such as screw, rivet and hollow roll body 30 It is connected, in such manner, it is possible to improve the sealing of the axial end portion of hollow roll body 30, reduces the entrance of dust.
Referring to Fig. 1, each roller seat 10 includes base 11, supporting arm 12 and the sleeve 13 being arranged on supporting arm 12, Supporting arm 12 is installed on the pedestal 11, and sleeve 13 has the cavity inserted for connecting portion 21, the cavity difference of each roller seat 10 An embedded second bearing 50, connecting portion 21 are articulated with by second bearing 50 in the cavity of sleeve 13.So, that is to say, that By setting clutch shaft bearing 40, hollow roll body 30 can rotate relative to roller carrier shaft 20, and by setting second bearing 50, roller carrier shaft 20 can Rotated relative to axis of the roller seat 10 around roller carrier shaft 20.
As further optimizing, fixing hole 14 is provided with base 11, can be by fasteners such as screw, rivets by base 11 fix, and make the whole structure of idler assembly 100 more firm.
The ribbon conveyer that the present embodiment provides, including belt conveyor, for guiding the above-mentioned idler machining of belt conveyor Part 100 and the transmission device for rotating belt conveyor, belt conveyor are paperwrapped in the outside of hollow roll body 30.
Above-mentioned ribbon conveyer, the idler assembly 100 provided using the present embodiment, is reduced card group phenomenon, improved Production efficiency.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Any modification, equivalent substitution or improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
