Description

Chain damper

Technical Field

The utility model belongs to the technical field of mechanical control, concretely relates to chain damper.

Background

Various friction and other damping effects, which exploit free vibration damping, we call damping. While the particular elements arranged on the structural system can provide resistance to movement, a device for dissipating the energy of movement, which is called a damper. The damper is also called a damping device, and is a device for increasing damping which is made in order to quickly damp vibration generated by impact. Various dampers are applied to the industries of aerospace, aviation, war industry, firearms, automobiles and the like for damping vibration and dissipating energy, and people gradually transfer the technologies to structural engineering such as buildings, bridges, railways and the like from the seventies of the twentieth century, so that the development is very rapid.

However, in the prior art, if the chain damper runs continuously, especially under a relatively large load condition, the problems of relatively fast mechanical temperature rise and relatively fast damage to friction plates often occur, which leads to the reduction of the service life of parts.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a chain damper to there is spare part to damage very fast problem among the solution prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a chain damper, includes the driving shaft, the driving shaft facial make-up is equipped with drive sprocket, the meshing is connected with the chain on the drive sprocket, the opposite side meshing of chain is connected with driven sprocket, driven sprocket facial make-up is equipped with the driven shaft, the workbin has been installed to one side of driven shaft, the both sides of workbin are equipped with the shoulder hole, the bearing has been installed in the shoulder hole, the driven shaft is worn out one section that the bearing got into the workbin and is installed the attenuator, the friction disc has been installed to one side of attenuator, the control wire has been installed to one side of attenuator, one side of workbin is equipped with the regulation hole, the regulation hole is worn out to.

Preferably, the work box is of a square box structure.

Preferably, a through hole is formed in one side of the working box, an air cooler is inserted into the through hole, and ventilation holes are distributed in the working box.

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

the utility model provides a chain damper, during the use, through arresting gear control pulling control wire, control wire passes through the attenuator and drives friction disc laminating driven shaft, utilizes the frictional force of friction disc and driven shaft, reaches the braking to the device, need not the friction disc and directly rubs with the chain to the life of extension spare part.

The utility model provides a chain damper starts the air-cooler through control terminal, and the air-cooler carries out the air-cooled cooling operation to attenuator and friction disc, reduces because of the friction produces the wearing and tearing of high temperature to the part.
