Abstract
The utility model provides a hinged type flexible belt clutching tensioner, used for the clutch of a short range belt drive device. The utility model is provided with a swing arm shaft (3) one end of which is hinged on a fixed shaft (2), the other end of the swing arm shaft is hinged with a connecting rod (1) through a shaft (4), and both ends of the connecting rod are respectively provided with a roller (5). When the clutching tensioner is tensioned, tension force applied on a belt is greatly decreased, and thereby, the reverse deformation of the belt is reduced, and stress conditions are improved for the belt. The two rollers are mutually balanced, and thereby, the role of buffering is played, the impact of load variation on the belt is reduced, and the service life of the belt is extended.
Description
The utility model provides a kind of mechanical mechanism, especially a kind of bel-drivenn engaging and disengaging gear.
A few thing machinery as garden supervisor on, the transmission of power is to finish by the belt on two belt pulleys and two belt pulleys.And the device of realizing two belt pulley clutches at present is, a roller is installed on Swing Arm, to the Swing Arm application of force, makes roller and belt closed contact so that belt tension rotates thereby make driving pulley drive driven pulley.This arrangement of clutch expanding force is big, and the distortion of belt straight-line distance is big, and belt and roller cornerite are little, and belt oppositely is subjected to folding power big, so the service life of belt is very short, can not satisfy normal operating needs.
The purpose of this utility model provides a kind of hinge type flexible belt clutch swelling device, to improve the service life of belt.
The utility model is achieved in that a kind of hinge type flexible belt clutch swelling device, and it has swing arm bar one end to be hinged on the dead axle, and the other end is hinged with connecting rod by axle, and the connecting rod two ends are equipped with roller.
Adopt the belt clutch swelling device of said structure, be installed in the belt outside on two belt pulleys during use.Changed the tensioner stress point of former clutch swelling device during tensioner, it is big that the cornerite of belt and roller becomes, the expanding force that acts on each stress point of belt reduces at double, and the reversal deformation of belt reduces significantly, has thoroughly improved the belt stress condition, two rollers can be with connecting rod swing in addition, two rollers are firmly even, and balance has buffer action mutually, reduced the impact of load change, thereby increased substantially the service life of belt belt.
Below in conjunction with description of drawings structure of the present utility model.
Fig. 1 is the scheme drawing of the utility model structure.Fig. 2 is the scheme drawing of the belt clutch tension mechanism before the utility model.
As shown in drawings, a kind of hinge type flexible belt clutch swelling device of the utility model, it has swing arm bar (3) one ends to be hinged on the dead axle (2), and the other end is hinged with connecting rod (1) by axle (4), and the connecting rod two ends are equipped with roller (5).
In off working state, two rollers do not contact with belt (7), and belt skids on driving pulley (6), and power can not pass to driven pulley (8), and driven pulley is motionless.
As applying an application force that makes progress in the Swing Arm front portion, two rollers contacts with belt simultaneously, and expanding force acts on the belt by roller, with belt tension, belt with the transmission of power of driving pulley to driven pulley, the driven pulley rotation.
The utility model is particularly suitable for the clutch of short range belt gear.
Claims (1)
1, a kind of hinge type flexible belt clutch swelling device is characterized in that, it has swing arm bar (3) one ends to be hinged on the dead axle (2), and the other end is hinged with connecting rod (1) by axle (4), and the connecting rod two ends are equipped with roller (5).
