Description
Technical field
The utility model relates to a kind of roller, particularly, relates to a kind of free roller.
Background technology
Roller is columniform part, divides driven roller and driven voller by purposes; Be divided into power drum and no-power drum by type of drive, power drum is divided into again single sprocket chain cylinder, double chain wheel cylinder, single 0 band cylinder, two 0 band cylinder; No-power drum is divided into interior tooth axle cylinder and spring pressing-in type rotary drum.Cylindrical drum and conical drum is divided into by version.Roller is widely used in as in all kinds of drive transfer systems such as circular screen printer, digital-code printer, mine conveying equipment, papermaking, package packing machine and sorting load transfer device.
Collect post at conveyor line, generally adopt roller transmission, when transmitting as adopted common roller, when material or staff are stuck between roll gap, equipment or the person usually can be made to come to harm, there is much unsafe hidden danger.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide a kind of free roller, and it is safe and reliable, eliminates above-mentioned potential safety hazard.
According to an aspect of the present utility model, a kind of free roller is provided, it is characterized in that, comprise the first lining, cylindrical shell, axle, friction lining, sprocket wheel, clutch shaft bearing, the second bearing, the second lining, bearing set, first lining, the second lining are all positioned at cylindrical shell, in first lining, in the second lining, all clutch shaft bearing is housed, clutch shaft bearing, the second bearing all coordinate with shaft clearance, sprocket wheel is positioned on one end of axle, second bearing is between sprocket wheel and axle, friction lining is between sprocket wheel and the second lining, and bearing set is positioned at sprocket wheel.
Preferably, the other end of described axle is connected with a nut.
Preferably, a pad is provided with between described nut and a spring.
Preferably, the side of described clutch shaft bearing is provided with hole elastic ring.
Preferably, described spring housing is on axle.
Preferably, the side of described second bearing is provided with a locating bush.
Compared with prior art, the utility model has following beneficial effect: one, structure and easy to assembly, and parts only need unclamp nut, can rapid-assembling, and during installation, regulating spring predetermincd tension gets final product normal operation.Two, long service life, easy to maintenance, this roller consumable accessory is friction lining, and actual use confirms, other parts are almost without wear phenomenon.Friction lining is changed and is also facilitated, and only need unclamp nut, does not need complicated dismantlement work.Three, safe and reliable.According to different materials in use procedure, or the predetermincd tension of the wear condition timely adjustment nut of wearing and tearing sheet, keep the normal operation of roller.Meanwhile, when when between two roll gap, card has foreign matter or a staff, roller produces skidding immediately and between friction lining, so just can the personal and device security of available protecting.
Accompanying drawing explanation
By reading the detailed description done non-limiting example with reference to the following drawings, other features, objects and advantages of the present utility model will become more obvious:
Fig. 1 is the structural representation of the free roller of the utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in detail.Following examples will contribute to those skilled in the art and understand the utility model further, but not limit the utility model in any form.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, some distortion and improvement can also be made.These all belong to protection domain of the present utility model.
As shown in Figure 1, the free roller of the utility model comprises the first lining 1, cylindrical shell 2, axle 3, friction lining 4, sprocket wheel 5, clutch shaft bearing 10, second bearing 11, second lining 13, bearing set 14, first lining 1, second lining 13 is all positioned at cylindrical shell 2, in first lining 1, in the second lining 13, clutch shaft bearing 10 is all housed, clutch shaft bearing 10, second bearing 11 all with axle 3 free-running fit, sprocket wheel 5 is positioned on one end of axle 3, second bearing 11 is between sprocket wheel 5 and axle 3, friction lining 4 is between sprocket wheel 5 and the second lining 13, and bearing set 14 is positioned at sprocket wheel 5.
The other end of axle 3 is connected with a nut 6, so conveniently carries out installing and keeping in repair.
Be provided with a pad 7 between nut 6 and a spring 8, by the predetermincd tension of nut 6 and pad 7 regulating spring, the friction force that sprocket wheel and cylindrical shell are produced tightly joins.
Spring 8 is enclosed within axle 3, so conveniently controls predetermincd tension.
The side of clutch shaft bearing 10 is provided with hole elastic ring 9.Circlip for bore 9 pairs of clutch shaft bearings 10 position, and prevent clutch shaft bearing from throwing off with roller in operation process.
The side of the second bearing 11 is provided with a locating bush 12, and sprocket wheel 5 is alignd by locating bush 12 roller identical with front and back.
Roller bearing running during external force band movable sprocket, transmission material; under abnormal condition; when staff or foreign matter are between roll gap; sprocket wheel remains in operation and cylindrical shell and friction lining skidding do not turn; play the protection person and device security effectively like this; avoid roller in transmitting procedure because of abnormal condition occur the person and equipment injury, installation, maintenance change efficient and convenient.Bearing set plays a supportive role to the sprocket wheel installed.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
