Problems solved by technology

Since the heat-resistant temperature of the encoder used in the hoist is usually relatively low, and it is restricted in the operating environment temperature, the temperature restriction of the encoder may become an obstacle to the miniaturization and thinning of the hoist

Embodiment 1

[0052] figure 1 It is a plan view of the hoistway of the elevator without a machine room according to one embodiment of the present invention. Such as figure 1 As shown, in the hoistway 1, an elevator car 4 guided up and down by a pair of elevator car side guide rails 3 fixed on the hoistway wall 2 and a counterweight guided up and down by a pair of counterweight side guide rails 5 are arranged. 6, and a winch 7 is arranged between the elevator car 4 and the hoistway 2. This winch 7 is made of frame body 8, the rotating frame that is cylindrical shape that is positioned at frame body 8 hoistway wall 2 sides, namely brake drum 9 and the sheave 10 that is supported by brake drum 9, brake drum 9 and sheave 10 have the same axis of rotation and are fixed to rotate synchronously with each other.

Abstract

The present invention relates to a winding engine for an elevator and an elevator device, wherein the winding engine for an elevator resolves the problem that the temperature of an encoder increases, thereby realizing miniaturization and thinning. The elevator device can also reduce the space required for arranging the winding engine between the wall of an elevating passage and an elevator car. In the present invention, a main shaft is hollow with one end communicating with the other end, and is provided with a containing space for containing an encoder used for detecting the rotation of a rotary framework, and is also provided with a through hole communicating with the containing space from the other end. The encoder contained in the containing space and fixed on the framework is connected with one end side of the encoder shaft with one end side inserted into the through hole from the other end side of the main shaft, the other end side of the encoder shaft is arranged to rotate together with the rotation framework, the encoder shaft in the containing space is provided with blades, and the encoder shaft is provided with a ventilation hole communicating the other end side of the encoder shaft with the inside of the containing space.

Description

technical field [0001] The present invention relates to an elevator hoist and elevator equipment that pull a load by winding a main rope around a sheave. Background technique [0002] In recent years, as elevators without a machine room in which the hoist is installed in the hoistway have become mainstream, the miniaturization and thinning of the hoist have been further developed. When the hoist is miniaturized and thinned, the temperature will further rise due to the reduction of the heat dissipation performance of the motor. In order to reduce the temperature rise of the motor, it has been proposed in the prior art to make the air flow by setting a fan structure, so as to reduce the temperature of the motor. A scheme in which the motor is forcedly air-cooled (for example, refer to Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1 Japanese Patent Application Publication No. 2008-517576 [0006] As elevators without a ...
