Problems solved by technology

The M28×1.5 thread used in the prior art is prone to seizure failure in harsh environments, and the drive wrench hexagonal SW17 is prone to slippage, while the 08A-1 transmission chain is thinner and easily broken when stuck
Due to the above-mentioned defects, the existing drive belt tensioning device has low working efficiency, and is often prone to failure of tensioning

Embodiment Construction

[0029] refer to figure 2 as shown, figure 2 Disclosed is a structural diagram of a transmission belt tensioner according to an embodiment of the present invention.

[0030] Such as figure 2 As shown, the transmission belt tensioning device includes: a bottom plate 202 , a top plate 204 , a screw rod 206 , a driving nut 208 and four nut sleeves 210 . The four corners of the bottom plate 202 are provided with support holes, and the four corners of the top plate 204 are provided with installation holes, and the positions of the installation holes correspond to the positions of the support holes. The screw rod 206 , the driving nut 208 and the nut sleeve 210 are installed on the four corners of the bottom plate 202 and the top plate 204 respectively, so the number of the screw rod 206 , the driving nut 208 and the nut sleeve 210 are four.

[0031] The bottom of each screw 206 in the four screws 206 is installed in a support hole, and the top passes through a corresponding in...

Abstract

The invention discloses a drive belt tensioning device. The drive belt tensioning device comprises a bottom plate, a top plate, screws, driving nuts and nut sleeves. Supporting holes are formed in the bottom plate; mounting holes are formed in the top plate; the bottoms of the screws are arranged in the supporting holes; the top portions of the screws penetrate through the corresponding mounting holes; the driving nuts are meshed with the screws and can rotatably ascend or descend along the screws; a chain wheel is arranged on the outer side of the top of each driving nut; the four chain wheels are meshed with one transmission chain to rotate in a linkage mode; the four driving nuts ascend or descend synchronously; the tops of the driving nuts are in contact with the bottom of the top plate to jack the top plate. The nut sleeves are arranged above the top plate and are meshed with the screws, and the bottoms of the nut sleeves are in contact with the top of the top late. The four driving nuts are rotated; the four driving nuts are driven by the chain wheels and the transmission chain to be in linkage, and the four driving nuts rotatably ascend along the screws to jack the top plate to ascend.

Description

technical field [0001] The invention relates to automobile production line equipment, more specifically, to a transmission belt tensioning device and a tensioning method. Background technique [0002] In the automobile production line, the engine production line is an important part. The cylinder block rough machining station is mainly used for rough machining the engine block. The rough machining station has a large cutting force and is dry machining, so the operating environment is relatively harsh. In the harsh operating environment, the transmission belt is easy to age and produce derivatives. It is necessary to use a transmission belt tensioner to tighten the belt to maintain the transmission performance of the belt. [0003] figure 1 A structural schematic diagram of a transmission belt tensioner used in the traditional technology is disclosed. The drive belt tightening device is composed of a base plate 102 and a top plate 104, which are connected to each other by ...
