Problems solved by technology
When an abnormally large amount of lubricating oil is accumulated in the oil reservoir, it is likely that an abnormality has occurred in the sealing structure. At this time, it is necessary to take corresponding measures as soon as possible. Thinning is the most important thing for thin hoists for elevators without a machine room

Embodiment Construction
[0059] Embodiments of the present invention will be described below with reference to the drawings.
[0060] Figure 4 It is a cross-sectional view of elevator equipment using a thin hoist for elevator equipment according to an embodiment of the present invention. An elevator car 2 and a counterweight 3 connected by a main rope (not shown) are installed in the hoistway 1 so as to be able to move up and down. There is a gap of about several hundred millimeters between the hoistway 1 and the elevator car 2, and the thin hoist 4 is installed in the gap of about several hundred millimeters so as to face the wall of the hoistway. The thin winch 4 has a frame body 5 and a sheave 6. The frame body 5 is used to accommodate the stator constituting the motor. The sheave 6 is integrally formed with the rotor core of the motor facing the stator, and the main rope is wound thereon. The thin hoist 4 is configured to rotate the sheave 6 together with the rotor core of the motor, thereby mo...

A low profile traction machine for elevators can store leaked lubricating oil in case of a fault in the sealing structure part, take measures to deal with the leakage as early as possible and have the axial lengthe shortened. A ring-shaped projection (13) integrally formed with a frame (5) is equipped on the periphery of a bearing housing (18). The ring-shaped projection is provided with a ring-shaped oil storer cover plate more adjacent to a rope wheel side than an opposite gap between the projecting part of the frame and the bearing housing. An oil dripping space part is formed on the lower part of an opposite gap located between the oil storer cover plate on the inner side of the ring-shaped projection and the frame. Connecting wires for connecting stator windings are equipped between the oil storer cover plate on the outer side of the ring-shaped projection and the frame. An oil reservoir communicated with the oil dripping space part and located on the lower part of the oil dripping space part is formed on the frame end face opposite to the rope wheel.
Description
technical field [0001] The present invention relates to a thin winch for elevator equipment used in elevator equipment. Background technique [0002] Generally speaking, the hoist and motor control devices used to make the elevator car go up and down in the elevator equipment, and the governor for emergency braking of the elevator car when the elevator car runs at overspeed, etc. are all installed in the building. In the mechanical room at the top of the object. On the other hand, in elevator equipment in which the elevator car is relatively slow in ascending and descending speed, a so-called machine room-less elevator apparatus in which a machine room is not provided has been widely used. In the above-mentioned elevator device without a machine room, all the equipment that should be installed in the machine room are installed in the hoistway, so the hoist is also installed in the hoistway. A variety of configurations can be used when the hoist is arranged in the hoistway,...
