Tension device for roller chain with chain wheel tension wheel

Abstract

The invention discloses a tension device for a roller chain with a toothed tension wheel, which is used on an inclinable rolling simple resistance rotary furnace. A resistance rotary furnace chain wheel is connected with a motor transmission shaft chain wheel by a roller chain; a chain wheel is sleeved outside a bearing, is close to the roller chain and tensions the roller chain; the bearing is sleeved on a bearing shaft; the other end of the bearing shaft is connected with a connecting plate in a right-angle mode; the connecting plate is provided with a plurality of mounting holes and is arranged on a rotary furnace shell by screws penetrating the mounting holes; the position of a tension chain wheel for adjusting tension degree of the roller chain can be realized by adjusting the position of the connecting plate through the screws; the tension chain wheel which is pressed against the roller chain is a toothed tension chain wheel; the toothed tension chain wheel is in tooth joint with the roller chain; and the roller chain and the tension chain wheel synchronous rotate. Through the tension device, wave type shake of the chain can be eliminated, the rotary furnace stably rotates, and the service life of the resistance rotary furnace, particularly a chain transmission mechanism, can be greatly prolonged.

Description

technical field [0001] The invention relates to a tensioning device for a transmission chain, in particular to a tensioning device for a roller chain with a sprocket tensioning wheel used on a simple resistance rotary kiln that can be tilted. Background technique [0002] At present, the RG series drum carburizing furnaces produced by Zhejiang Changxing Zhengda Electric Furnace Factory, such as the multiple 45-60 kW tiltable drum resistance rotary furnaces used by our company, all use chain transmission devices. That is, the resistance rotary furnace sprocket and the motor drive shaft sprocket are connected by a roller chain. There are roller chain tensioners in chain drives. The tensioning wheel of its roller chain tensioning device pushes the roller chain from the outside of the roller chain so that the roller chain is always in tension. The main structure of the tensioning device is as follows: the middle of the tensioning wheel is a bearing and a bearing shaft. The be...

AI Technical Summary

Problems solved by technology

The disadvantage of the toothless tensioner is that the tensioned roller chain will produce wave-like vibration, and the wave-like vibration of the roller chain will cause the resistance rotary furnace to also produce wave-like vibration

This wavy vibration will greatly affect the service life of the resistance rotary furnace, especially the chain drive mechanism
