As shown in fig. 1-22, the flattening massage chair of the involute toothed chain track convenient for the manipulator to walk comprises a back frame 1, a seat frame 2 and a manipulator 3, wherein the back frame 1 is arranged on the seat frame 2, the flattening massage chair further comprises a toothed chain 4, one end of the toothed chain 4 is arranged on the back frame 1, the other end of the toothed chain 4 is arranged on the seat frame 2, the toothed chain 4 comprises a plurality of chain tooth plates 41, two tooth parts 411 are respectively arranged at the head and tail parts of each chain tooth plate 41, wherein the head and tail tooth parts of two adjacent chain tooth plates 41 along the length direction of the toothed chain 41 are in hinged fit through a pin shaft 42, the hinged fit can be round pin type connection as shown in fig. 7, bearing bush type connection as shown in fig. 8 or roller type connection as shown in fig. 9, and a chain wheel 31 meshed with the toothed chain 3 is arranged on the manipulator 3.
Engagement mode of toothed chain: in the process of meshing the chain and the chain wheel, the outer side straight tooth profile of the chain plate of the chain is meshed with the tooth profile of the straight tooth or involute tooth profile of the chain wheel, so that two outer sides of a single piece of chain tooth are embedded on the involute arc surfaces of two grooves between the tooth spans of the chain wheel, and the meshing process is to be abbreviated as: in the process of rotating the chain wheel, the 30-degree outer inclined straight edge of one side of the chain is in contact with the involute gear without side gaps and slides according to the involute, and when the chain wheel rolls to the 30-degree outer inclined straight edge of the other side of the chain and slides and is attached to the other tooth-crossing side of the chain wheel in a 'bow-crossing' type manner, the meshing of the chain and the machining track of the cutter are completely overlapped. Because of no sprocket backlash, the engagement mode has the functions of elastic buffering and noise elimination. Since the sprocket meshing is a relatively static bonding process without dynamic involute meshing developing motion, the involute toothed chain is in a quasi-conjugate meshing relationship relative to the alternating meshing process of dynamic involute curves of two gears to achieve a constant transmission ratio. The manner in which the toothed chain engages the sprocket is shown in fig. 10.
Because of the meshing relationship of the toothed chains, the toothed chains are also called silent chains, and are formed by hinging a set of sprocket plates. When in operation, the chain toothed plate is meshed with the sprocket teeth to transfer motion, a guide plate 6 is arranged beside the toothed chain 4, and the guide plate 6 is arranged on the elastic substrate 51 to prevent the lateral movement of the chain when in operation. The guide plate has an inner guide plate and an outer guide plate. The tooth-shaped chain of the inner guide plate has good guidance performance and reliable work; the chain wheel of the outer guide plate toothed chain has simple structure. Compared with a conventional roller chain, the envelope curve formed by the toothed chain is round at the top of the gear teeth, and the envelope curve of the roller chain is round at the root of the gear teeth, so that the toothed chain has long meshing transition section and extremely large gap in the initial meshing section, the purpose can ensure that the tooth shape at the tail end of the roller chain in the rolling direction can be smoothly meshed, and the defects make the roller chain unsuitable for power transmission by a short envelope curve or a single tooth. Therefore, the working mode of the tooth-shaped chain gapless transmission has the advantages of stability, no noise, good impact resistance and reliable operation.
The quasi-conjugate meshing relationship realized by the constant pitch characteristic of the toothed chain almost ensures that the sprocket and the toothed chain can keep a relatively constant transmission ratio relationship from the beginning of meshing to the end of meshing, and the meshing process is a constant pitch meshing process.
