Description

Technical Field

[0001] The utility model relates to an auxiliary device for belt transmission, in particular to a novel V-belt tensioning device. Background Art

[0002] Belt transmission device is a conventional device for mechanical transmission, which is widely used in various industries. It has the advantages of simple structure, easy use and maintenance. However, when the belt transmission device is running, the belt is easy to loosen, causing the belt to slip; at the same time, if the belt is too tight, the belt will bear too much tension, which will affect the transmission efficiency at the least, and cause the belt to burn out due to friction between the belt and the pulley, affecting the service life.

[0003] After the belt has been running for a period of time, it will become longer due to the increase in temperature and elastic deformation. If there is no external intervention, the belt will be in a loose working state. If it is in a loose working state for a long time, the belt will slip and reduce the transmission efficiency, and even burn out due to excessive temperature rise. Therefore, it is very beneficial to invent a new type of V-belt tensioning device. Summary of the invention

[0004] The utility model aims to provide a novel V-belt tensioning device to solve the defects of the prior art, which can prevent the transmission belt from slipping and improve the transmission efficiency.

[0005] In order to solve the above problems, the technical solution of the utility model is implemented as follows: it includes a movable seat (1), an upper pressure plate (2), a round nut (3), a stop washer (4), a tensioner bearing push rod (5), a tensioner shaft (6), a tensioner (7), a locking screw (8), and a transmission screw (9), characterized in that: the movable seat (1) is connected to the upper pressure plate (2) of the upper pressure plate through the locking screw (8) to form a sliding track of the belt tensioning device, which is convenient for the transmission of the auxiliary device; the tensioner shaft (6) passes through the tensioner (7) and the tensioner bearing push rod (5) and is fixed on the movable seat (1), and a transmission screw (9) is connected to one side of the movable seat (1). The tensioner (7) is freely rotated with the tensioner shaft (6) as the axis; the tensioner shaft (6) is installed together with the movable seat through the round nut (3) and the stop washer (4), which can prevent the tensioner shaft from loosening.

[0006] The V-belt tensioner receives force F from the belt, and in order to ensure that the belt is in a tensioned state, the V-belt tensioner rotates along direction N with the transmission screw, and the position of the tensioner is adjusted through the screw transmission, and moves in direction V, so that the belt receives a force opposite to force F, thereby tightening the belt.

[0007] The utility model has the beneficial effect that the movable seat can be conveniently moved in the opposite direction of the belt force through the transmission screw (9), so that the tensioning device tightens the belt in the opposite direction to prevent the belt from loosening, thereby improving the transmission efficiency of the transmission belt.

[0011] The utility model is further described below in conjunction with the accompanying drawings;

[0012] like Figure 1 , Figure 2 As shown, the utility model comprises a movable seat (1), an upper pressure plate (2), a round nut (3), a stop washer (4), a tensioner bearing push rod (5), a tensioner shaft (6), a tensioner (7), a locking screw (8), and a transmission screw (9), characterized in that: the movable seat (1) is connected to the upper pressure plate (2) of the upper pressure plate through the locking screw (8) to form a sliding track of the belt tensioning device, which is convenient for the transmission of the auxiliary device; the tensioner shaft (6) passes through the tensioner (7) and the tensioner bearing push rod (5) and is fixed on the movable seat (1), and a transmission screw (9) is connected to one side of the movable seat (1). The tensioner (7) is freely rotated with the tensioner shaft (6) as the axis; the tensioner shaft (6) is installed together with the movable seat through the round nut (3) and the stop washer (4), which can prevent the tensioner shaft from loosening. The transmission screw (9) can be rotated by manual adjustment and mechanical adjustment.

[0013] like Figure 3 As shown, the V-belt tensioner receives force F from the belt. To ensure that the belt is in a tensioned state, the V-belt tensioner rotates along direction N with the transmission screw, and the position of the tensioner is adjusted through the screw transmission, moving in direction V, so that the belt receives a force opposite to force F, thereby tightening the belt.
