Description

Tensioning mechanism

Technical Field

The utility model relates to a belt tensioning field especially relates to a straining device.

Background

The belt transmission is also called as "belt transmission" and is a mechanical transmission, which is formed by tightly sleeving one or more belts on two wheels (called as "belt pulleys"), the two wheels are respectively arranged on a driving shaft and a driven shaft, and the friction between the belts and the two wheels is utilized to transmit motion and power.

When current belt is in work for a long time or the belt is hot, the size of belt can the grow, makes the belt skid at the belt pulley or drop to influence the normal work of machine, when solving it, through with drive machine shut down, go again to adjust, but partial drive belt's tensioning position is comparatively narrow and small, makes drive belt adjust comparatively inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the following problems existing in the prior art: when current belt is in work for a long time or the belt is hot, the size of belt can the grow, makes the belt skid at the belt pulley or drop to influence the normal work of machine, when solving it, through with drive machine shut down, go again to adjust, but partial drive belt's tensioning position is comparatively narrow and small, makes drive belt adjust comparatively inconvenient.

For solving the problem that prior art exists, the utility model provides a straining device, which comprises a fixing frame, the middle part of mount is provided with the rotor plate and runs through pivot I of mount and rotor plate, the both ends inboard of rotor plate is equipped with pivot III and pivot II respectively, the outside cover of pivot II is equipped with the take-up pulley, a pot head of mount is equipped with pivot IV, pivot III with the inboard cover of pivot IV is equipped with the screw rod, the cover is equipped with spring, gasket and nut about the one end of screw rod, the spring is connected with pivot IV.

Preferably, one end of the fixing frame is provided with a mounting plate, through holes are formed in two ends of the mounting plate, and the structure is used for mounting the tensioning mechanism.

Preferably, the number of the fixed frames and the number of the rotating plates are two, a space is reserved between each of the two shaft pins I and the two rotating plates, and the structure is used for installing the rotating plates and the tensioning wheel.

Preferably, the shape of the shaft pin I and the shape of the rotating plate are both arc-shaped, and the structure is used for preventing the rotating plate of the fixing frame from scratching the belt.

Preferably, the other end of the screw is provided with a baffle, the size of the baffle is matched with that of the shaft pin III, and the structure is used for preventing the shaft pin III from falling off.

Preferably, the perforating hole of mounting panel is waist type hole, and this structure is comparatively convenient when being used for making the mounting panel installation.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses combine mount, rotor plate, axis of rotation, spring and bolt assembly, aim at through twisting on moving the nut makes spring mounting screw rod, the tension of spring passes through gasket and nut and drives the screw rod removal, the screw rod removes the interval that makes pivot III and pivot IV and reduces, makes the rotor plate rotate on the mount through pivot I, makes the position of take-up pulley shift up, makes the belt continuously be in fastening state to need not to make transmission machinery shut down and adjust work.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1-2, a tensioning mechanism is assembled from:

assembly description: firstly, a shaft pin III 8 and a shaft pin IV 10 are sequentially sleeved on a screw rod 9, a shaft pin II 5 is sleeved on the inner side of a tension wheel 4, two ends of two rotating plates 3 are respectively sleeved on the shaft pin II 5 and the shaft pin III 8, one ends of two fixing frames 1 are sleeved on the shaft pin IV 10, the shaft pin I2 is inserted in the middle of the fixing frame 1 and the rotating plates 3, then a nut 11 is screwed to enable a spring 6 and a gasket 7 to be installed on the screw rod 9, and the fixing frame 1 is installed on an installation plate 12.

Description of the working principle: when the tension adjusting device is used, the spring 6 generates tension between the shaft pin IV 10 and the gasket 7, the tension of the spring 6 drives the screw rod 9 to move through the gasket 7 and the nut 11, the screw rod 9 moves to reduce the distance between the shaft pin III 8 and the shaft pin IV 10, the rotating plate 3 rotates on the fixing frame 1 through the shaft pin I2, and the position of the tension wheel 4 moves upwards.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
