摘要： Chain detachment and chain entry are avoided, and a process for setting the length of a meshing chain is avoided, while the chain feed length can also be freely changed. A meshing chain stopper (190L) comprises a meshing chain stopper attachment part (191) and a contact-stop protrusion (192). The contact-stop protrusion (192) is contact-stopped at a contact-stop point (173A) provided on the periphery of a chain locus (L) when a pair of meshing chains (150, 150) are being driven.

摘要： A hoisting and lowering driving engagement multi-row chain is disclosed, in which bending of the connecting pins in the chain is suppressed to avoid fatigue failure. Additionally, the load carrying balance in the chain width direction is improved, and contact vibrations and contact noises generated between the chain and the hoisting and lowering sprockets are suppressed. Endurance of the bush in the chain is thereby improved. Bending of connecting pins is avoided by press-fitting bushes, through which connecting pins pass, into intermediate tooth plates. This also improves load carrying balance widthwise. Contact noises and vibrations between the bushes and sprockets are suppressed by providing bushes with a separate sprocket engagement portion having a larger diameter than the press-fitting portion of the bushes.

摘要： In order to stably drive a body to be driven such as a lifting table, an engagement chain type device (100) for forward and backward movement is configured in such a manner that a pair of engagement chains (110, 110) has rigid chain portions (110D). The rigid chain portions (110D) are configured in such a manner that, within a predetermined range from the front ends of the chains in the direction in which the pair of engagement chains (110, 110) is rigid, inner tooth plates (111) are constantly engaged with each other and outer tooth plates (112) are constantly engaged with each other. Square column-shaped reinforcement core members (140) fitted in the square column-shaped hollow sections (S) of the rigid chain portions (110D) are connected to mounting members (C).

摘要： An engagement chain type hoisting and lowering device is disclosed, having a hoisting and lowering table attached to the upper end of two or more pairs of hoisting and lowering driving engagement chains. A driving motor drives two pairs of hoisting and lowering sprockets which, in turn, raise or lower two pairs of hoisting and lowering driving engagement chains. By arranging two pairs of hoisting and lowering driving engagement chains on two opposed sides of the hoisting and lowering table, buckling of the hoisting and lowering driving engagement chains is suppressed, resulting in stable hoisting and lowering operations without slippage of articles on the hoisting and lowering table, and chain endurance is improved. The device is designed so that the lowest position of the hoisting and lowering table can be lower than the height of the peripherally located driving motor, for ease and safety of operation and maintenance.

摘要： An interlocking chain type forward and backward actuating device is provided that does not increase workload involved in assembling the device, adjusting the rotation phase, and servicing and maintaining the device. The device is capable of smoothly actuating a driven body by advancing and retracting the body, and of preventing any pulsation or the like of the meshing chain. The interlocking chain type forward and backward actuating device includes chain-guide grooves formed so as to equalize an interlocked-state pin-to-pin distance (D1) between a pair of connecting pins that face each other in a chain interlocking imaginary plane (S) and a rigid-state pin-to-pin distance (D2) between a pair of connecting pins.

摘要： Provided is an interlocking chain forward and backward actuating device type device, the device being configured so that the space within the device is effectively utilized and that a device configuration most suitable for driving interlocking chains is selected to enable the interlocking chains to be smoothly driven. An interlocking chain type forward and backward actuating device (100) is configured in such a manner that a pair of flat face-shaped chain support faces (132AS, 132AS) which sandwich and support a rigid chain portion (110G) from both sides thereof each form a portion of each of the guide groove faces (132, 132) of chain guide grooves (131, 131) while being continuously connected to each of a pair of curved guide faces (132BS, 132BS) which respectively guide disengaged portions (110H, 110H) of a pair of interlocking chains (110, 110), the disengaged portions (110H, 110H) having been disengaged from each other.
