This utility model relates to a kind of belt conveyor, the belt of a kind of toothed belt transmission
Belt conveyor is widely used in the place needing to transmit article in a large number, existing belt conveyor
It is to drive cylinder side that motor reducer is installed, directly driving cylinder, deposit and take in the direction of the width
The problems such as space is bigger.
If employing motorized pulleys, but there is size limitation and can not meet little very well in diameter and driving power
Space is high-power waits actual demand.
Utility model content
The high-power grade in little space can not be met very well real for belt conveyor roller existence in prior art
The deficiencies such as border demand, the technical problems to be solved in the utility model is to provide that a kind of space hold is little, peace
The belt conveyor of the toothed belt transmission of dress and convenient later maintenance.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
The belt conveyor of a kind of toothed belt transmission of this utility model, has bearing, drive roll, drives
Moving device and active synchronization belt wheel and driven synchronous pulley, the crossbeam of bearing uses sheet metal structural, drives
Dynamic device and active synchronization belt wheel are installed in the bottom space of below crossbeam, and drive roll two ends are passed through
Self-aligning ball bearing is installed on crossbeam, and driven synchronous pulley is axially connected with drive roll.
Driven synchronous pulley is arranged between crossbeam and cylinder.
Crossbeam is provided with hole, and driven synchronous pulley is arranged on outside self-aligning ball bearing, is installed on the most same
Timing Belt between step belt wheel and driven synchronous pulley is passed by the hole being located on channel-section steel.
This utility model also has swelling device, is located at belt conveyor tail, including chute, tensioner
Plate, tensioner fixed block and tension bolt, wherein chute is fixed on crossbeam, and tensioner fixed block is fixed
In chute, tightening plate has horizontal strip hole, is fixed in chute after bearing, follower rollers are installed,
Hold out against after being screwed in fixed block tapped through hole by tensioner screw.
This utility model has the advantages that and advantage:
1. the form of this utility model toothed belt transmission drives, and space hold is little, installs and later maintenance
Convenient, impact resistance after Timing Belt, response rapidly, synchronicity good, concrete cost is relatively low, simple in construction,
The features such as maintenance and repair is convenient.
Tail the most of the present utility model has swelling device, and its simple in construction, mounting and adjusting are convenient, same
In the case of sample fed distance, the practical length of belt conveyor is less, and joint eliminates conventional belt conveying
The machine two bend pulleys needed for the swelling device that lower section is arranged and a belt tensioning drum, complete set of equipments
Cost is relatively low.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further elaborated.
As shown in Figure 1,3, the belt conveyor of a kind of toothed belt transmission of this utility model, have bearing,
Drive roll 6, driving means and active synchronization belt wheel 1 and driven synchronous pulley 2, the crossbeam of bearing
7 use sheet metal structural, and driving means and active synchronization belt wheel 1 are installed on the bottom space of crossbeam less than 7
In, drive roll 6 two ends are installed on crossbeam 7 by self-aligning ball bearing 5, driven synchronous pulley 2
Axially it is connected with drive roll 6.
Driven synchronous pulley 2 may be mounted between crossbeam 7 and cylinder 6, can lengthen cylinder 7 with
Distance between bearing；Also may be installed outside self-aligning ball bearing 5, as it is shown in figure 1, when driven same
When step belt wheel 2 is arranged on outside self-aligning ball bearing 5, on crossbeam 7, perforate 8, is installed on active synchronization
Timing Belt 3 between belt wheel 1 and driven synchronous pulley 2 is passed by the hole 8 being located on crossbeam 7.
This utility model uses panel beating support beam, and self-aligning ball bearing 5, drive roll are installed in cylinder two ends
The axle processing keyway of 6 is used for installing belt wheel；Motor 4 is arranged on inner side below belt feeder, and output shaft is pacified
Dress active synchronization belt wheel 1, drives drive roll 6 by Timing Belt 3；Speed reducer output shaft and bearing group
Part center connecting shaft is respectively mounted same specification synchronous pulley；Driven synchronous pulley on drive roll 6
To be arranged between two ends self-aligning ball bearing 5, it is possible to be arranged on outside two ends self-aligning ball bearing 5.
By self-aligning ball bearing 5 mounting rotary drum 6, it is possible to prevent shelf both sides alignment error to produce axiality
The when of bad, self-aligning ball bearing can compensate error, improves mechanism kinematic situation, it is also possible to improves
The impact of the countershaft operation of amount of deflection of the axle caused because of belt pretightning force
This utility model also has swelling device, as in figure 2 it is shown, be located at belt conveyor tail, and bag
Including chute 10, tightening plate 9, tensioner fixed block 11 and tension bolt 12, wherein chute 10 is affixed
On crossbeam 7, tensioner fixed block 11 is fixed in chute 10, and tightening plate 9 is provided with horizontal strip
Hole, is fixed in chute 10 after installing bearing, follower rollers, tensioner screw screw in fixed block screw thread
Hold out against after through hole.This structure holds out against belt, tightening plate by tensioner screw and slides in chute, thus
Realize the tensioner function of belt.
This utility model drives active synchronization band to drive the driven synchronization on drive roll by electrical machine belt pulley
Belt wheel, considers for saving space etc., belt feeder crossbeam uses sheet metal structural, can meet little very well
Space is high-power waits actual demand.
