Abstract
The utility model discloses a non-return carrier roller with a long service life, no welding and low noise. The non-return carrier roller comprises a bearing support, a fastening shaft, a non-return piece, a non-return seat, a non-return sleeve, a roller surface, a carrier roller shaft and a sealing piece. The bearing support and the roller surface are assembled in an interference fit manner; the bearing support is connected with the non-return seat through the fastening shaft; the non-return piece is connected with the fastening shaft and is arranged between the bearing support and the non-return seat; the non-return sleeve is connected with the carrier roller shaft through a key; and the sealing piece is arranged in the bearing support. The non-return carrier roller with the long service life, no welding and low noise has the reasonable structure, is convenient to install and adjust, can bear high non-return torque, can effectively prevent an upper conveying belt-type conveyor from sliding down and rotating reversely caused by current failure or rubber belt fracture, and can lead the conveyor to be safe and reliable to operate.
Description
Technical field
The utility model relates to a kind of high life, exempts from welding, low noise Non-return idler, is mainly used in upper conveying belt type conveyer.
Background technology
Belt conveyer is mainly by carrying roller, and support, compositions such as transfer drive, carrying roller are one of main composition parts of belt conveyer, use the most extensive.Because belt speed and freight volume is different, the oad of carrying roller is different.Carrying roller kind commonly used has: impact idler, parallel roll, aligning carrier roller etc.
At present, the belt conveyer carrying roller mainly contains following kind both at home and abroad
1. parallel roll
Be used for the return leg support belt
2. impact idler:
Be installed in material feeding section below, reduce the suffered impact of load-transfer device
3. aligning carrier roller:
Be used to adjust belt deflection
But above-mentioned all kinds of carrying rollers itself all do not have braking function, and conveyer also needs to add in addition special brake equipment and carries out the braking of equipment.This will cause braking force to be concentrated, and can't realize the reliable parking of belt conveyer, reduce the safety of equipment.
The utility model content
The purpose of the utility model provides a kind of high life, exempts from welding, low noise Non-return idler.
The purpose of the utility model realizes through following technical scheme:
The high life of the utility model, exempt from the welding, the low noise Non-return idler, comprise bearing seat, tightening axle, check sheet, check seat, check cover, roller skin, roller carrier shaft and sealing member.Bearing seat and roller skin interference fit, bearing seat is connected through the tightening axle with the check seat, and the check sheet is connected on the tightening axle, is located between bearing seat and the check seat, and the check cover is connected through key with roller carrier shaft, and sealing member is located in the bearing seat.
Technical scheme by above-mentioned the utility model can be found out; The described high life of the utility model, exempt from welding, the low noise Non-return idler is rational in infrastructure; Installation, easy to adjust; The check moment of bearing is big, and downslide and reversing in the time of can preventing belt conveyer because of outage or adhesive tape fracture effectively make conveyer safe and reliable to operation.

The specific embodiment
The high life of the utility model, exempt from the welding, the low noise Non-return idler; The specific embodiment that it is preferable such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7; High life, exempt from welding, low noise Non-return idler, comprise bearing seat 1, tightening axle 2, check sheet 3, check seat 4, check cover 5, roller skin 6, roller carrier shaft 7 and sealing member 8.
Bearing seat 1 and roller skin 6 interference fit, bearing seat 1 is connected through tightening axle 2 with check seat 4.
Check cover 5 and roller carrier shaft 7 are connected through key, and sealing member 8 is located in the bearing seat 1.
Bearing seat 1 adopts the design of U type annular seal space, and check cover 5 adopts swallowtail-shaped structure design, sealing member 8 employing labyrinths 6 loculus non-contact type structures.
For overcoming the deficiency of existing carrying roller and brake equipment, in conjunction with the requirement of multiple delivery system operating condition, the utility model is designed a kind of high life, is exempted from welding, low noise Non-return idler, can realize effective check.This device has improved the reliability of conveyer, has prolonged the service life of conveyer, has reduced the operation and maintenance expense of conveyer.The utility model has following innovative point:
High life, exempt from welding, low noise Non-return idler bearing seat adopts the design of U type annular seal space, forms airtight negative pressure space in the rotary course, has the effect of dustproof and waterproof;
High life, exempt from welding, low noise Non-return idler check cover adopts the swallowtail-shaped structure design, can the bilateral check, the impulsive force when reducing check can be stirred the check sheet when centnifugal force is not enough;
High life, exempt from welding, low noise Non-return idler check seat is provided with 4 check positions, check flexible movements, check cover chucking check sheet when guaranteeing the carrying roller check;
High life, exempt from welding, low noise Non-return idler check seat, bearing seat and roller skin and all adopt coaxial cooperation to press-fit, exempt from welding, thereby avoid the high temperature deformation influence, coaxial accuracy is high;
High life, exempt from welding, labyrinth 6 loculus non-contact type sealing members are adopted at low noise Non-return idler two ends, have the dustproof and waterproof function, damping coefficient is low, carrying roller rotates flexibly.
Below in conjunction with accompanying drawing to the high life, exempt to weld, the principle of work of low noise Non-return idler further specifies:
High life, exempt from welding, the low noise Non-return idler is installed on the upper conveying belt type conveyer support, when belt conveyer brought into operation, the carrying roller rotative speed was lower, check sheet 3 suffered centnifugal forces are less than its gravity, check cover 5 is stirred check sheet 3; When the rotating speed of carrying roller reached normal speed, check sheet 3 was attached on the inwall of roller skin 6 in 2 rotations of centrifugal action lower edge tightening axle, and this moment, check sheet 3 can not contact with check cover 5, and its mode of operation is as shown in Figure 6.
When the belt conveyer emergency braking; Carrying roller speed under the friction force effect of conveyor belt running drops to zero and the trend of reversing arranged, this moment since the centnifugal force of check sheet 3 less than its gravity, an end of check sheet 3 falls and check cover 5 comes in contact; Fall between check seat 4 and the check cover 5 " stuck "; Prevent the carrying roller reversing, thereby stoped the load-transfer device reversing, its mode of operation is as shown in Figure 7.
The beneficial effect of the utility model is:
Rational in infrastructure, installation, easy to adjust, applicability is strong;
Noise is low during operation, and it is little to wear and tear;
Operating efficiency is high, and non-maintaining, operating cost is low.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical personnel of being familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
