PURPOSE: To share a gear motor provided with a brake having the same capacity by combining a gear motor provided with a brake wherein a motor, a reduction gear, and a brake are integrally formed with a reduction gear device composed of chain gears and a chain. CONSTITUTION: In a hoisting machine 21, a sheave 7 is directly attached to the shaft end of a gear motor 29 provided with a brake and fixed to machine beams 14 through a machine base 23 and a vibrationproof rubber 13. A chain pinion 27 is attached to the shaft end of the gear motor 29 provided with the brake. A chain gear 39 is attached to the shaft end of a winding drum 17 arranged next to the gear motor 29 provided with the brake, and the chain gears 37, 39 are connected to each other by a chain 38, and the gear motor 29 provided with the brake and the winding drum 17 are fixed on the machine base 24. Thereby, the speed ratio to the winding method can be obtained by the chain gear deceleration by adding the chain gears 37, 39 and the chain 38 in the winding drum method, thereby the gear motor 29 provided with the brake can be shared.

In the hoisting machine of the prior art described above, in the case of an elevator with a trunk, since the arrangement in which the balance weight 4 is dropped to the side of the hoistway is space efficient, the hoisting machine is improved. 4, the clearance S 1 between the end of the brake 11 of the hoisting machine 6 and the wall of the machine room 2 becomes narrower. For this reason, there are many problems that the space for maintenance and inspection cannot be secured.

Further, comparing the motor capacities of the winding system and the winding cylinder system, since the winding system has a balance weight, it is generally sufficient that the capacity is capable of moving up and down by half the passenger load. On the other hand, the winding drum type requires a large capacity for raising and lowering the passenger load + the car's own weight. Therefore, the hoisting machine motor and the brake of the elevator specifications (FIGS. 3, 4, and 5 to 6) have substantially the same capacity. However, because the speeds were different, the reduction ratio of the reducer had to be changed, and it was necessary to prepare and combine a completely different reducer, and it was not possible to share it.
