摘要： A hoist (1) that is provided with a regenerative resistor (11) and contains the following in a casing (2, 3, and 20): a load-raising/lowering motor (7) driven by an inverter control device (12) and provided with a forced-cooling means (19); and a mechanism part (9) containing a reduction mechanism part (8) and a load sheave (10) that uses power from the reduction mechanism part (8) to take up and let out a chain. The load-raising/lowering motor (7), mechanism part (9), inverter control device (12), and regenerative resistor (11) are distributed inside the casing (2, 3, and 20) so as to achieve a balance of weight about the center of gravity (O) of the load applied when raising or lowering. Also, the inverter control device (12) and the regenerative resistor (11) are affixed to the casing (2, 3, and 20), in close contact therewith, in parts of the casing separated from each other with the mechanism part (9) therebetween. The layout of the inverter control device (12), motor (7), regenerative resistor (11) and the like is thus taken into consideration while making it possible to suitably dissipate heat using the forced-cooling means (19), thereby providing a hoist (1) capable of frequent operation.

摘要： The present invention solves the above-described problems, and is a torque transmission device including: a low-torque input means 8; output rotating means 11 configured to be magnetically coupled with the low-torque input means so as to generate a thrust force in response to a load; and high-torque input means 15 configured to engage the output rotating means 11 at the time of a high-load rotation and transmits a torque, wherein the low-torque input means 8 includes: pole teeth 9 configured to oppose the magnetic pole rotating bodies 12 of the output rotating means to be magnetically coupled thereto at the time of low-load rotation, and side magnetic bodies 10 configured to oppose the magnetic pole rotating bodies 12 slid by a thrust force generated by the relative rotation between the magnetic pole rotating bodies 12 and the pole teeth 9 and to be magnetically coupled thereto at the time of high-load rotation, the output rotating means includes the magnetic pole rotating bodies 12, a permanent magnet 13 clamped between the magnetic pole rotating bodies 12, and a claw clutch portion 14 configured to engage the high-torque input means 15 at the time of high-load rotation. The torque transmission device of the related art has a problem in that the power transmission cannot necessarily be achieved sufficiently at the time of the high-load and clutch performance may not function sufficiently. Also, a rotation-thrust converting mechanism for causing the speed switching member to operate includes, a converting mechanism having an intermediate disk provided with a permanent magnet and an output disk provided with a magnetism for a magnetic spring which provides a returning force to a magnet for moving the intermediate disk, and the intermediate disk, and the converting mechanism being complicated in configuration and having a large number of components is provided separately from the transmission body, so that the configuration of the transmission becomes complicated and large-sized and, since the number of the components is increased, the cost is also increased.
