Description

Synchronous belt tension mechanism

Technical field

The utility model belongs to the mechanical transmission technical field, is specifically related to a kind of synchronous belt tension mechanism.

Background technique

Timing Belt is to take wire rope or glass fibre to be strength layer, outward coated with the endless belt of polyurethane or neoprene, band interior week make dentation, itself and profile of tooth belt wheel are meshed.During toothed belt transmission, velocity ratio is accurate, little to the axle active force, compact structure, and oil resistant, wear resistance is good.

Current synchronous belt tension mechanism adopts tension wheel structure mostly, and the Fastening mechanism more complicated of this structure is installed trouble, adjusts the expanding force of Timing Belt is difficult, in using process, easily produces Timing Belt deflection phenomenon.

The model utility content

The utility model provides a kind of synchronous belt tension mechanism, and installation trouble, expanding force that prior art exists are difficult for adjusting and the problem of Timing Belt deflection to solve.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of synchronous belt tension mechanism, mainly by tension bolt, tension bolt connecting plate, the adjustable fixed plate of Timing Belt, Timing Belt regulator plate, two Timing Belt profile of tooth pressing plates, two Timing Belt fixed plates and Timing Belt horizontal pressure foot, formed, the adjustable fixed plate of tension bolt connecting plate and Timing Belt is fixed by screws in together, the Timing Belt regulator plate is positioned in the chute of the adjustable fixed plate of Timing Belt, tension bolt passes tension bolt connecting plate and Timing Belt regulator plate, can regulate the distance that the Timing Belt regulator plate moves, realize the adjustment to belt tension; The Timing Belt regulator plate is connected and an end of Timing Belt is fixed with a Timing Belt profile of tooth pressing plate by screw, a Timing Belt fixed plate and another piece Timing Belt profile of tooth pressing plate are fixed the other end of Timing Belt by screw, between two Timing Belt profile of tooth pressing plates, the Timing Belt horizontal pressure foot is set, Timing Belt horizontal pressure foot and another piece Timing Belt fixed plate are fixed Timing Belt by screw; Timing Belt fixed plate below the adjustable fixed plate of Timing Belt and Timing Belt horizontal pressure foot is fixed by screws in respectively on the tensioner attachment face, and another piece Timing Belt fixed plate is fixed by screws on fixed installation face.

Between above-mentioned Timing Belt regulator plate and Timing Belt profile of tooth pressing plate, the Timing Belt follower gasket is housed, excessive to prevent impacting force.

Between above-mentioned Timing Belt fixed plate and Timing Belt profile of tooth pressing plate, the Timing Belt follower gasket is housed, excessive to prevent impacting force.

Between above-mentioned Timing Belt horizontal pressure foot and Timing Belt fixed plate, the Timing Belt follower gasket is housed, excessive to prevent impacting force.

Working principle of the present utility model is: when needs are regulated belt tension, unclamp the fastening screw trip bolt between Timing Belt fixed plate and Timing Belt horizontal pressure foot, regulate tension bolt, can realize that Timing Belt regulator plate, Timing Belt follower gasket and Timing Belt profile of tooth pressing plate move together with an end of the Timing Belt chute along the adjustable fixed plate of Timing Belt, after adjusting to suitable tension force, the fastening screw trip bolt of locking Timing Belt fixed plate and Timing Belt horizontal pressure foot gets final product.

Compared with the prior art, the utility model compact structure, be easy to install, and easy to adjust, impacting force is large, can avoid again Timing Belt to thread off simultaneously, tensioner while both can be used for the monolateral use of Timing Belt, tensioner in the time of also can using for the Timing Belt annular.

The accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.
