Problems solved by technology

The chain tensioning device in the prior art generally does not have the automatic compensation function, and cannot realize the flexible tensioning function. That is to say, due to the transmission characteristics of the chain, after a long time of power transmission, the chain is easy to stretch and relax, and the excessive relaxation needs to be adjusted in time. Tensioning, the chain tensioning device without compensation function requires manual adjustment of the chain tensioning device, which seriously affects the production efficiency in the workplace with high chain tension, which is not conducive to the realization of industrial automation production
In some special cases, reliable chain tensioning and anti-loosening methods are required to realize the transmission, especially when the sprocket is driven in the horizontal direction, because the chain will have the inherent characteristics of relaxation due to long-term work, under its gravity, it will appear Tooth skipping, or even off-chain situations, causing safety hazards and seriously affecting work efficiency

Embodiment approach

[0033] Implementation method: Before pre-installing the flexible chain tensioning device, adjust the adjusting screw so that the two swing arm rods are at the maximum angle under the unstressed state, and ensure that the pre-assembly angle of the two swing arm rods is greater than 100°, so as to improve the tension. Compensation amount, at this time the spring is in an unstressed state. The installation base plate and the preset mounting bracket (not described) are fixed by fixing bolts passing through the waist-shaped mounting holes 14, and the design of the waist-shaped mounting holes can be used to fine-tune the installation position. Apply outward pulling force to the two swing arm levers to increase the angle between the two swing arm levers. At this time, the spring is in a stretched state, and the tensioning sprocket at the end of the swing arm lever cooperates with the chain to be tensioned, and the external force is removed. Such as Figure 8 As shown, during the ten...

Abstract

The invention discloses a flexible chain tensioning device. The flexible chain tensioning device comprises two symmetrically-arranged rocker arm assemblies, a spring assembly and a mounting bottom plate. The rocker arm assemblies comprise tensioning chain wheels, chain wheel shafts and rocker arm rods, the tensioning chain wheels are rotationally assembled at the top ends of the rocker arm rods through the chain wheel shafts, the bottom ends of the rocker arm rods are hinged to the mounting bottom plate, and the spring assembly is assembled between the two rocker arm rods in a crossing manner. According to the chain tensioning device, flexible tensioning is conducted on a chain, the functions of automatic compensation and automatic tensioning adjustment are achieved, the potential safety hazards of gear skipping and chain disengaging happening in the chain transmission process are reduced, and meanwhile the working efficiency of chain tensioning operation is improved.

Description

technical field [0001] The invention relates to the technical field of chain tensioning, in particular to a flexible chain tensioning device. Background technique [0002] The sprocket and the chain are the two major components of the sprocket transmission system. In order for the chain to achieve the tension required by the working conditions, a chain tensioning device is usually designed and arranged in the sprocket transmission system. The chain tensioning device in the prior art generally does not have the automatic compensation function, and cannot realize the flexible tensioning function. That is to say, due to the transmission characteristics of the chain, after a long time of power transmission, the chain is easy to stretch and relax, and the excessive relaxation needs to be adjusted in time. Tensioning, a chain tensioning device without compensation function requires manual adjustment of the chain tensioning device, which seriously affects production efficiency in a...
