Detailed Description
The utility model will be described in detail with reference to the accompanying drawings and detailed description.
The utility model provides a chain transmission tensioning device, which is shown in fig. 1 and 2, and comprises a bracket 2, wherein a vertical plate 13 is fixed above the bracket 2, a reinforcing rib plate 14 is fixed between one side of the vertical plate 13 and the bracket 2, and a positioning plate 3 is fixed above the top end of the vertical plate 13 through a screw 15. A longitudinal guide rod 4 is fixed between the positioning plate 3 and the bracket 2, and the upper end and the lower end of the guide rod 4 are respectively fixed with the positioning plate 3 and the bracket 2 through screws 15. The guide sleeve 5 is sleeved outside the guide rod 4 in a sliding manner, and the bushings 12 are sleeved outside the guide rod 4 at the upper end and the lower end of the guide sleeve 5, so that abrasion of the guide sleeve 5 is reduced. One side of the guide sleeve 5 is connected with a chain wheel 7 positioned outside the bracket 2 through a horizontal pin shaft 6, and the positioning plate 3 is provided with an up-down adjusting mechanism connected with the guide sleeve 5. The upper and lower adjusting mechanism comprises a longitudinal screw rod 8, the top end of the screw rod 8 upwards penetrates through the locating plate 3 and is in threaded connection with an adjusting nut 9 located above the locating plate 3, the bottom end of the screw rod 8 downwards penetrates through the guide sleeve 5 and is fixed with the guide sleeve, locking nuts 10 are in threaded connection with the screw rod 8 at the upper end and the lower end of the guide sleeve 5 respectively, and cotter pins 11 are arranged on the screw rod 8 corresponding to the locking nuts 10.
During operation, as shown in fig. 3, the bracket 2 is close to the chain 1, the chain wheel 7 is arranged below the chain 1, when the chain 1 is in a loose state, the adjusting nut 9 on the positioning plate 3 is rotated to enable the screw rod 8 to move upwards, at the moment, the screw rod 8 is fixed with the guide sleeve 5 through the locking nut 10 and the cotter pin 11, the guide sleeve 5 is sleeved outside the guide rod 4 in a sliding manner, the guide rod 4 can limit the screw rod 8 to drive the guide sleeve 5 to rotate, the screw rod 8 can only move axially relative to the adjusting nut 9, and when the screw rod 8 moves upwards, the guide sleeve 5 and the pin shaft 6 and the chain wheel 7 on the outer side of the guide sleeve are driven to move upwards until the chain wheel 7 and the chain 1 are in effective engagement, and at the moment, the loose chain 1 is in a tensioning state, and transmission is more efficient. When the chain 1 or the chain wheel 7 needs to be maintained, the adjusting nut 9 is rotated to enable the screw rod 8 to descend, and the guide sleeve 5, the pin shaft 6 and the chain wheel 7 are driven to descend until the chain 1 is in a loose state. In the process, the vertical plate 13 supported by the reinforcing rib plate 14 can provide higher stability for the positioning plate 3, and ensures stable rotation of the adjusting nut 9.
