2results about How to "Enough tension" patented technology

The utility model relates to a big capacity head and tail double -drive reversible matching bin belt conveyor, include, frame, the frame one end is provided with head drive part, and the frame other end is provided with the tensioning trolley, the frame other end still is provided with tail tensioning spare, the tail tensioning spare with tensioning trolley connects, be provided with first cylinder and second cylinder on the frame, be connected with the belt between first cylinder and second cylinder, head drive part connects with first cylinder, be provided with tail drive part on the tensioning trolley, tail drive part with second cylinder connects, the utility model under the action of tensioning device can move back and forth, realize head and tail bidirectional drive's while, guarantee that the belt has enough tension in each place, and it is not prone to the phenomenon of skidding, realizes the distance long capacity bidirectional reversible matching equipment configuration.

The application discloses an anti-skid tensioning wheel for automobile transmission and belongs to the technical field of tensioning wheels. The anti-skid tensioning wheel comprises a mounting seat, a pressure plate slidably connected to the mounting seat, a wheel frame slidably connected to the pressure plate, a pressure spring arranged on the pressure plate, and a tensioning wheel rotatably connected to the wheel frame. A non-circular insertion column is slidably connected to the wheel frame. An adjusting screw is rotatably connected to the pressure plate. A driving ring is rotatably connected to the mounting seat. The driving ring is in transmission connection with a transmission belt. The pressure plate and the wheel frame slide relative to each other to drive the non-circular insertion column to slide. When the pressure plate and the wheel frame are located at positions close to each other, the tensioning wheel keeps pressing the transmission belt. When the pressure plate and the wheel frame are located at positions far away from each other, the tensioning wheel slides to the transmission belt and further presses the transmission belt. When the transmission belt slips, the tensioning wheel slides to further press the transmission belt. After slipping, the tensioning wheel can provide tension to the transmission belt again. The transmission belt can be conveniently disassembled. The anti-skid tensioning wheel adopts a pure mechanical structure, and the failure rate is reduced.
