Abstract
The invention discloses a tension device, which comprises a torsion box (3) and a chain wheel device (1). The chain wheel device (1) comprises a transmission shaft (2) and a chain wheel (9), a small shaft (8) is arranged on the transmission shaft (2) which is installed on the torsion box (3) through the small shaft (8), a disc-shaped spring (4) is arranged at one end of the torsion box (3), a mandrill of the disc-shaped spring (4) is connected with a dry oil cylinder (5), and a manual oil feeding device is connected with the dry oil cylinder (5) through a hydraulic pipe (6). The tension device is capable of achieving automatic tensioning of a chain, high in automation degree, small in occupied space, simple in structure and low in using cost. The disc-shaped spring of the tension device has good buffer effect and is capable of effectively prolonging service life of the device.
Description
Technical field
The present invention relates to mechanical manufacturing field, especially a kind of tension device.
Background technique
At present; The tension device that is used for semi portal formula scraper reclaimer of the prior art all needs artificial adjustment, can not realize that complete machine is unattended and mechanical, electrical, liquid integrated, and whole device has no buffer unit; The loss of equipment is bigger; And the tension device volume ratio of existing technology is bigger, floor space with take up room all bigger, whole device underaction.
Summary of the invention
The present invention is in order to solve the deficiency of present tension device existing technology, a kind of tension device to be provided, comprise torsion box 3 and chain gear apparatus 1 for this reason; Chain gear apparatus 1 comprises transmission shaft 2 and sprocket wheel 9; Transmission shaft 2 is provided with little axle 8, and transmission shaft 2 is installed on the torsion box 3 through little axle 8, and torsion box 3 one ends are provided with cup spring 4; The mandrel of cup spring 4 and drier oil cylinder 5 join, and manually fuel-servicing equipment joins through hydraulic tube 6 and drier oil cylinder 5 through surveying oil gear 7.
The invention has the beneficial effects as follows:
Tension device of the present invention can be realized the chain auto-tensioning, and automaticity is high, and occupation space is little, and is simple in structure, and user cost is low, and the cup spring that this device is provided with has played good buffer function, can effectively prolong the working life of equipment.
Description of drawings
The present invention will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a tension device schematic representation of the present invention.
