Abstract
The utility model relates to a chain tensioning device. The chain tensioning device comprises a supporting plate, and is characterized in that: a transverse chute is formed on the supporting plate; a blocking wall is arranged at the end part of the chute; a sliding block is arranged in the chute; a shaft hole is formed in the middle of the sliding block; a tensioning rod which is accordant with the sliding direction of the sliding block and penetrates through the blocking wall is connected to a side end face of the sliding block; a spring is sleeved on the tensioning rod on the outer side of the blocking wall; and a spring compression nut is arranged on the end part of the tensioning rod. The chain tensioning device has the advantages that: a chain can be always kept in a tensioned state to ensure normal running of equipment.
Description
Technical field:
The utility model relates to a kind of chain stretching device, belongs to mechanical field.
Background technique:
In mechanical transmission, usually adopt chain transmission, chain can be lax gradually in transmission process, and not only influence transmission efficiency, even can the operation of entire equipment be impacted, as on the sorting cigarette line, the lax accuracy that can influence letter sorting of chain.
Summary of the invention:
The purpose of the utility model provides a kind of chain that can make all the time and is in the chain stretching device of tensioning state.
The purpose of the utility model realizes in the following manner:
The utility model comprises dunnage; It is characterized in that: on dunnage, have horizontal concrete chute, there is retaining wall the end of chute, is provided with slide block in the chute; The middle part of slide block has axis hole; Be connected with the nutted rod that pass retaining wall consistent with the slide block glide direction on the side end face of slide block, on the nutted rod in the retaining wall outside, be with spring, the end of nutted rod is equipped with the spring compression nut.
The utility model has the advantages that: can make chain be in tensioning state all the time, guarantee the normal operation of equipment.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
With reference to accompanying drawing, the utility model comprises dunnage 1, on dunnage 1, has horizontal concrete chute 2; There is retaining wall 7 end of chute; Be provided with slide block 3 in the chute 2, the middle part of slide block 3 has axis hole 4, is connected with the nutted rod that pass retaining wall 5 consistent with the slide block glide direction on the side end face of slide block 3; On the nutted rod in retaining wall 7 outsides, be with spring 8, the end of nutted rod 5 is equipped with spring compression nut 6.
During use; Two cover chain stretching devices are located at the two ends of sprocket drive system sprocket wheel driven axle respectively, two axle heads of sprocket wheel driven axle, the slide block axis hole that overlaps chain stretching device with nut and is respectively fixed; Tighten spring compression nut 6, make spring 8 be in compressive state.When chain occurs laxly in transmission process, spring 8 can promote nutted rod 5 automatically and drive slide blocks 3 and in chute 2, slide, with chain tension.
