Description
Technical field
This utility model relates to a kind of belt pulley adjusting means.
Background technology
Conveyer belt, also known as conveyer belt, is to play carrying in belt conveyor and transport rubber and fiber, the metal composite goods of material effect, or the goods that plastics and fabric are combined.Conveyer belt, belt conveyor is widely used in the various solid blocks of conveying and powder shape material or work piece in agricultural, industrial and mining establishment and transportation, conveyer belt energy serialization, high efficiency, high-inclination conveying, conveyer belt operation safety, conveyer belt is easy to use, and maintenance is easily, freight charges are cheap, and transportation range can be shortened, reduce construction costs, use manpower and material resources sparingly.
Conveyer belt of the prior art, including belt pulley and belt, belt pulley includes driven pulley and drivewheel, needing first driven pulley and drivewheel to be arranged in frame, belt it is generally required to longer than the distance of driven pulley left end to drivewheel right-hand member, so could be successfully arranged on driven pulley and drivewheel by the length of belt, but the rate of tension of belt is the most relatively low, therefore, after installation, belt all can become slack and undisciplined, less stable；Conveyer belt, when carrying object, the most easily makes object jolt, even falls.
Utility model content
This utility model is intended to provide a kind of rate of tension belt pulley adjusting means improving belt.
Belt pulley adjusting means in this programme, including frame, driven pulley and drivewheel, drivewheel is rotatably connected in frame, the first bearing is slidably connected in described frame, driven pulley is rotatably connected on the first bearing, first bearing has tooth bar away from the side connection of drivewheel, tooth bar is engaged with gear, slide bar is slidably connected in frame between first bearing and drivewheel, flexible part is connected between slide bar and the first bearing, connecting on slide bar has screw rod, screw flight to be connected in frame, and screw rod has nut away from the side of slide bar is threaded.
The know-why of this programme and have the beneficial effect that frame can be used to fixing whole belt pulley adjusting means, plays the effect supporting whole device, makes whole belt pulley adjusting means stably to run.
When changing or install belt, first rotating gear, gear driven tooth bar moves, and tooth bar will promote driven pulley near the motion of the direction of drivewheel, and the distance between drivewheel and driven pulley shortens；Simultaneously because slide bar is bolted in frame, slide bar will not move, and elastic component will be compressed.
Then belt is put on driven pulley and drivewheel, swing pinion, gear driven tooth bar moves, rack drives driven pulley is moved to the direction away from drivewheel, distance between drivewheel and driven pulley is elongated, and belt will be strained by drivewheel and driven pulley, thus improve belt tightening, improve the stability of conveyer belt, elastic component stretches；Then rotating nut, screw rod will be want near the motion of the direction of nut, screw rod band moving slide-bar moves to close or away from driven pulley direction, and elastic component will be compressed or stretch, and the rate of tension of elastic component improves, and by the first bearing tension or compression, thus improve the stability of the first bearing, further increase the stability of conveyer belt, and when carrying object, conveyer belt will be less susceptible to make object jolt, and object is also less susceptible to fall from conveyer belt.
Further, elastic component is spring.Spring structure is simple, easy for installation, it is easy to control its rate of tension so that the stability of the first bearing is easily controllable.
Further, gear connects motor.Starting motor, gear rotates, and facilitates the control to gear.
Further, slide bar is provided with limited block away from the frame of the side of drivewheel, and limited block is provided with rubber blanket near the side of slide bar.The setting of fiber block, can make slide bar move distance limited, it is therefore prevented that the distance that slide bar motion is excessive, makes spring-compressed or stretches excessive and lost efficacy；Rubber blanket can avoid limited block directly to contact with slide bar, it is therefore prevented that limited block mutually collide with slide bar or phase mutual friction and be lost, extend the use time of limited block and slide bar.
Further, frame being bolted the second bearing, drivewheel is rotatably connected on the second bearing.Bolt is easily installed and dismantles, and facilitates installation and the replacing of the second bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model belt pulley adjusting means embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: frame 1, tooth bar 2, gear 3, screw rod 4, driven pulley 5, spring 6, slide bar 7, nut 8, bolt 9, drivewheel 10, limited block 11, rubber blanket 12.
nullEmbodiment is basic with reference to shown in Fig. 1: belt pulley adjusting means，Including frame 1、Driven pulley 5 and drivewheel 10，Drivewheel 10 connects the first motor，The first bearing is slidably connected in frame 1，Driven pulley 5 is rotatably connected on the first bearing，Connected by bolt 9 in frame 1 and have the second bearing，Drivewheel 10 is rotatably connected on the second bearing，Connect on the left of first bearing and have tooth bar 2，Tooth bar 2 is engaged with gear 3，Gear 3 connects the second motor，Slide bar 7 is slidably connected in frame 1 between first bearing and drivewheel 10，It is welded with spring 6 between slide bar 7 and the first bearing，Connect on slide bar 7 and have screw rod 4，Screw rod 4 is threaded in frame 1，Threaded on the left of screw rod 4 have nut 8，Welded limiting block 11 in frame 1 on the left of slide bar 7，Rubber blanket 12 it is bonded with on the right side of limited block 11.
When changing or install belt, first starting the second motor, rotate gear 3, gear 3 band carry-over bar 2 moves, and promotion driven pulley 5 is moved right by tooth bar 2, and the distance between drivewheel 10 and driven pulley 5 shortens；Being fixed in frame 1 simultaneously because slide bar 7 is bolted 9, slide bar 7 will not move, and spring 6 will be compressed.
Then belt is put on driven pulley 5 and drivewheel 10, continue swing pinion 3, gear 3 band carry-over bar 2 moves, tooth bar 2 is made to drive driven pulley 5 to left movement, distance between drivewheel 10 and driven pulley 5 is elongated, and belt will be strained by drivewheel 10 and driven pulley 5, thus improve belt tightening, improve the stability of conveyer belt, spring 6 stretches；Then rotating nut 8, screw rod 4 will be to left movement, screw rod 4 band moving slide-bar 7 is to left movement, and moving to the position of limited block 11 always, slide bar 7 offsets with rubber blanket 12, and spring 6 will be compressed simultaneously, and the rate of tension of spring 6 improves, and the first bearing is compressed, thus improve the stability of the first bearing, further increase the stability of conveyer belt.
Starting the first motor, the first driven by motor drivewheel 10 rotates, and drivewheel 10 is rotated by belt drive driven pulley 5, and belt will stably operate.
Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic too much describes at this.Should be understood that; for a person skilled in the art, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
