Abstract
The utility model provides a tension device. A tension wheel is mounted on a bearing pedestal. The tension device is characterized by further including an elastic element, which can drive the tension wheel to move through the bearing pedestal so as to tension a flexible element on the tension wheel. In the utility model, the bearing pedestal is driven through the elastic element, then the tension wheel is driven to move, and the flexible element on the tension wheel is subjected to dynamic tension, thereby solving the problems in the flexible transmission, such as looseness of the flexible element or inaccurate positioning of moving object; and the tension device has a simple and compact structure, and is stable and reliable.
Description
Technical field
The utility model relates to a kind of tension device, relates in particular to a kind of flexible transmission tension device.
Background technique
Tension device is widely used in the flexible transmission of industries such as metallurgy, mine, coal, building materials, light industry, harbour, electric power, chemical industry.Traditional flexible transmission tension device is the static type tension device, can not realize dynamic tension to flexible member, causes flexible member loosening easily, reduces stability of transmission and reliability, thereby causes the location of moving object inaccurate, influence control effect.
The model utility content
The purpose of this utility model is to provide a kind of accurate positioning and reliable and stable tension device.
The purpose of this utility model is to realize like this, a kind of tension device, Idle wheel is installed on the bearing support, it is characterized in that: also comprise elastic element, move the flexible member tensioning that makes on the Idle wheel thereby described elastic element can drive described Idle wheel by bearing support.
For stability and the reliability that improves tension device, above-mentioned bearing support is provided with upper and lower guide rail and constitutes closed frame, and elastic element is connected with described bearing support by the link that is arranged on the described closed frame.
For simple in structure, compact, above-mentioned link comprises the screw rod that is arranged on the above-mentioned closed frame and places the interior nut of described closed frame that described nut sleeve is contained on the screw rod and with described bearing support contact and is connected.
Above-mentioned elastic element is connected with above-mentioned screw rod by middle connecting base.
Above-mentioned elastic element is oil hydraulic cylinder, cylinder, belleville spring, annular spring or cylindrically coiled spring.
The belt pulley that the sprocket wheel that above-mentioned Idle wheel is the static pulley used of wire rope, heavily loaded pitch chain is used, the sprocket wheel that the sleeve roller chain is used or belt transmission are used.
Above-mentioned flexible member is wire rope, heavily loaded pitch chain, sleeve roller chain or belt.
Above-mentioned Idle wheel is driving wheel or follower.
Above-mentioned bearing support also can be axle bed, and bearing places in the Idle wheel.
Above-mentioned nut and above-mentioned bearing support or axle bed are structure as a whole.
Above-mentioned screw rod, nut, middle connecting base and bearing support or axle bed are structure as a whole.
During operation, elastic element drives screw rod by intermediate connector and moves, and screw rod drives bearing support by nut and moves with Idle wheel, makes the flexible member tensioning on the Idle wheel.
The utlity model has following beneficial effect, the utility model drives bearing support by elastic element, thereby driving Idle wheel moves, flexible member on the Idle wheel is implemented dynamic tension, not only effectively solve the loosening or moving object of the flexible member that runs in the flexible transmission and located inaccurate problem, and it is simple in structure, compact, stable, reliable.
