In the figure, 1 base, 13 spacing grooves, 2 elastic rubber plates, 3 mounting plates, 4 spacing plates, 5 connecting ribs, 6 through holes, 7 sinking grooves, 8 clearance grooves, 91 outer chain sheets, 92 inner chain sheets, 93 rollers and 94 pin shafts.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following description, in conjunction with the examples and the accompanying drawings, is intended to illustrate the present invention in further detail, and the exemplary embodiments and the description thereof are only used for resolving the present invention, and are not intended to limit the present invention.
The utility model provides a prevent rocking transmission chain piece, includes base 1 and locates the elastic rubber plate 2 on the base 1, downwardly extending on the 1 bottom surface of base two relative mounting panels 3, be equipped with on the mounting panel 3 can with the round pin axle 94 through-hole 6 of mutual assembly of transmission chain, base 1 bottom surface middle part still downwardly extending two limiting plates 4, two limiting plates 4 are located two between the mounting panel 3, adjacent form spacing groove 13 that can hold chain 92 and outer chain 91 in one side of the chain simultaneously between limiting plate 4 and mounting panel 3, the groove width sum of two limiting grooves 13 is less than the clearance sum of chain 92 and outer chain 91 in the chain.
As shown in fig. 1 and 2, because the two mounting plates 3 have certain elasticity, two pin shafts 94 of the chain after the two mounting plates 3 are spread apart during installation can penetrate into the two through holes 6, in order to firmly connect the transmission chain block with the chain, the inner side surfaces of the two mounting plates 3 and the outer side surfaces of the outer chain pieces 91 on both sides of the chain are clamped, so that only the inner chain block which is likely to transversely move in the transmission process is the inner chain block, because the sum of the groove widths of the two limiting grooves 13 is smaller than the sum of the gaps between the inner chain pieces 92 and the outer chain pieces 91 of the chain, and the two inner chain pieces 92 are respectively installed in the corresponding limiting grooves 13, the inner chain piece 92 on each side can only move within the range limited by the corresponding limiting groove 13, and the limited movement greatly reduces the impact and noise generated in the work and the conveying of materials is more stable. Since the limiting function of the limiting groove 13 depends on the inner side surface, the height of the limiting plate 4 is not too high, and the limiting groove can be in a discontinuous structure along the length direction, so long as the limiting groove 13 which can block the transverse movement of the inner chain piece 92 is formed with the mounting plate 3.
The two limiting grooves 13 have the same width.
Therefore, the gaps between the inner chain block and the outer chain sheets 91 on the two sides can be evenly distributed into the two limiting grooves 13, the inner chain block is located in the middle of the chain when working, the amount of the transverse excursion of the inner chain block is equally divided, and the total excursion amount is reduced as much as possible.
The two limiting plates 4 are connected through thin-wall connecting ribs 5.
The connecting ribs 5 serve to reinforce and prevent the deformation of the limit plate 4.
The connecting ribs 5 are respectively positioned at two ends of the two limiting plates 4.
The connecting ribs 5 are positioned at the two ends of the limiting plate 4, so that the two limiting plates 4 form a frame structure with a more stable and reliable structure.
The connecting ribs 5 transversely extend towards two sides respectively, and form a sinking groove 7 with the adjacent mounting plate 3.
As shown in fig. 3 and 4, the existence of the sinking groove 7 can maintain the bending property of the mounting plate 3, and the transversely extending connecting rib 5 and the two limiting plates 4 form a well-shaped structure with more stable and reliable structure.
Two clearance grooves 8 for avoiding two rollers 93 of the chain are arranged in the middle of each of the two limiting plates 4.
As shown in fig. 2 and 4, the height of the limiting plate 4 can be increased properly, the clearance groove 8 can avoid the roller 93 in the middle, and the heights of the two ends of the limiting plate 4 are relatively high, so that the effective contact surface between the inner side surfaces of the inner chain sheet 92 and the inner side surfaces of the two ends of the limiting plate 4 which move relatively is increased, and the chain is always in the limiting groove 13 even when the chain turns.
It is to be understood that the foregoing examples merely represent preferred embodiments of the present invention, and that the description thereof is more specific and detailed, but not intended to limit the scope of the invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present invention, and all of them belong to the protection scope of the present invention.
