The utility model relates to a chain or belt tensioning device, which is characterized by comprising a rotating shaft, a pair of chain wheels or belt pulleys, a pair of slide sleeves, a pair of guide rails and weight connectors, wherein the rotating shaft is arranged above a chain or belt in a direction being vertical to a chain or belt transmission direction, the chain wheels or belt pulleys are respectively connected to the two axial sides of the rotating shaft and are connected with the chain or belt in a transmission way, the slide sleeves are connected to the two axial sides of the rotating shaft and are connected with the rotating shaft in a rotating way, the guide rails are fixedly connected onto a rack in the vertical direction, are respectively arranged on the two axial sides of the rotating shaft and are matched with the slide sleeves in a sliding way for guiding, and the weight connectors are arranged on the slide sleeves and are used to be connected with weights. The chain or belt tensioning device not only has good elastic adjustment effect, but also can adapt to load changes of the chain or belt to achieve appropriate tensioning effect. Moreover, the tensioning purpose can also be realized in case of failure in long-term use. Therefore, the normal operation of a chain or belt transmission mechanism can be guaranteed.
Description
Technical field
The utility model relates to a kind of chain or belt stretcher.
Background technique
Chain-driven or band transmission are mechanical drive mode comparatively commonly used, in the course of the work, because the load of chain or belt constantly changes, and chain or belt are elongated owing to wear and tear in use for some time, make chain or belt occur vibrations easily, come off, phenomenon such as skid, also can cause power loss simultaneously, the waste fuel oil, must solve these problems by the rate of tension of regulating chain or belt, existing adjusting chain or the common way of belt tightening are to apply a pre-tensioning to chain or belt, and adopt spring that chain or belt are carried out tensioning, but the spring that adopts is flexible adjustment weak effect not only in the course of the work, and elasticity lost efficacy easily in use for some time, thereby easily had influence on the proper functioning of chain or belt gear.
Summary of the invention
In order to solve existing in prior technology the problems referred to above, the purpose of this utility model is to provide a kind of chain or belt stretcher, not only flexible adjustment is effective for it, the load change that can adapt to chain or belt plays suitable tension, and no matter therefore how long use can not guarantee the proper functioning of chain or belt gear because of inefficacy can't realize the tensioning purpose.
The purpose of this utility model is achieved through the following technical solutions: a kind of chain or belt stretcher, it is characterized in that it comprises perpendicular to chain or belt transmission direction and is set up in chain or the rotatingshaft of belt top, be connected to the pair of sprocket or the belt pulley that are used for being connected transmission of the axial both sides of rotatingshaft with chain or belt, the a pair of sliding sleeve that is connected in the axial both sides of rotatingshaft and is rotationally connected with rotatingshaft, vertically be fixed on the frame and lay respectively at the axial both sides of rotatingshaft a pair of be used for sliding sleeve be slidingly matched guiding guide rail and be located at the weight link that being used on each sliding sleeve is connected weight.
In the technique scheme of the present utility model, sliding sleeve drives the sprocket wheel be connected to the axial both sides of rotatingshaft or belt pulley to pressing down chain or belt by rotatingshaft, thereby chain or belt are applied downward pre-tensioning, because sliding sleeve is slidingly matched with the perpendicular guide rail of establishing, therefore sliding sleeve relatively guide rail slide up and down, thereby drive rotatingshaft and sprocket wheel or belt pulley in the vertical direction are done and are moved up and down, make tension device described in the utility model can play suitable tension, thereby guarantee the proper functioning of the driving mechanism of chain or belt according to the load change of chain or belt.
In the technique scheme of the present utility model, a kind of chain or belt stretcher, it also comprises and lays respectively at the radially left and right sides and perpendicular to chain or belt transmission direction and be set up in chain or a pair of positioning shaft of belt below of rotatingshaft, and the axial both sides of each positioning shaft are respectively equipped with and are used for a pair of axle sleeve or the Bearing Installation seat that are connected the pair of sprocket or the belt pulley of transmission with chain or belt and are used for being connected with frame.
In addition, the utility model technique scheme has also been done following improvement:
Described weight link comprises connecting rod that is connected in the sliding sleeve bottom and the positioning element that is used for supporting weight that is connected in the connecting rod bottom, the sidepiece of described weight is provided with the opening slot of being convenient to the socket connecting rod, is convenient to change as required the weight of different quality like this.
Come off or produce when moving up and down with the weight link for fear of weight and rock, described connecting rod is a screw rod, is connected with on the described screw rod to be used for pinning the nut of weight downwards.
Compared to prior art, advantage of the present utility model is: not only flexible adjustment is effective, the load change that can adapt to chain or belt plays suitable tension, and no matter therefore how long use can not guarantee the proper functioning of chain or belt gear because of inefficacy can't realize the tensioning purpose.
