Abstract
A rotor having a smaller diameter than a support member is rotatably supported on the support member through a bearing. A stator is fixed to the support member. A sheave having in the outer periphery thereof a rope groove around which a rope is wound is mounted to a projecting small-diameter section of the rotor. A brake drum having a greater diameter than the sheave is formed on the rotor. A brake drum cover for covering a side surface of the brake drum is mounted to that side surface of the support member which is on the sheave side. A groove is formed in that portion of the sheave which is on the brake drum side, and the inner end of the brake drum cover is inserted in the groove.

The motor part of the towing machine that is made of stator 11 and rotor 2 is divided into the pancake of core length much smaller than iron core diameter.In addition, not shown brake plate (brake Pad) is sticked in brake wheel 8, is that towing machine is braked to rotor 2.
Patent documentation 1: TOHKEMY 2003-134768 communique
In above-mentioned existing pancake elevator hoist, be provided with the brake wheel cover 13 that covers brake wheel 8 sides in the rope sheave 6 side sides of supporting member 1, and the internal diameter of brake wheel cover 13 is greater than the external diameter of rope sheave 6, therefore, the oil that is contained on the rope 7 that the rope groove 6a of the periphery of rope sheave 6 go up to twine by rope sheave 6 periphery and between interior week of brake wheel cover 13 and probably attached to the side of brake wheel 8, attached to the oil of these brake wheel 8 sides flow to brake wheel 8 peripheries under the action of centrifugal force and brake plate between sliding surface, may obviously reduce braking force.
Summary of the invention
The present invention makes in order to solve above-mentioned problem, and its purpose is to obtain a kind of side of oil contained on the rope of car attached to brake wheel that can prevent to be used to hang, and can prevent to reduce the pancake elevator hoist of braking force.
According to a technical scheme of the present invention, the rotor rotation that diameter is littler than supporting member diameter freely is bearing on this supporting member the pancake elevator hoist by bearing, on supporting member, be fixed with stator, and, outstanding minor diameter part at rotor is equipped with rope sheave, this rope sheave has the rope groove that twines rope in periphery, this rope is used to be suspended on the car of lifting in the elevator hoistways, on rotor, be formed with the diameter brake wheel bigger than rope sheave diameter, the brake wheel cover of the side that covers brake wheel is installed in the rope sheave side side of supporting member, wherein, be arranged with groove at the brake wheel sidepiece of rope sheave, the inner of brake wheel cover is inserted in this groove.
According to another technical scheme of the present invention, form the return portion of turning back laterally in the inner of above-mentioned brake wheel cover, and, be provided with the accommodation section that holds this return portion at above-mentioned groove.
According to above technical scheme, be arranged with groove at the brake wheel sidepiece of rope sheave, the inner of brake wheel cover is inserted in this groove, the brake wheel cover is between rope and brake wheel, prevent the side of the oil of rope, prevent the outer peripheral face of oil, prevent that braking force from reducing attached to brake wheel attached to brake wheel.
In addition, according to another technical scheme, the inner of above-mentioned brake wheel cover in being inserted into the groove of rope sheave forms the return portion of turning back laterally, and, be provided with the accommodation section that holds this return portion at above-mentioned groove, stop the side of the oil of rope by the brake wheel cover between rope and brake wheel attached to the brake wheel cover, also the accommodation section by this return portion of the groove of the return portion of brake wheel cover the inner and rope sheave stops the side of the oil of rope attached to the brake wheel cover, prevent side and the side face of oil more reliably, prevent reliably that further braking force from reducing attached to the brake wheel cover.
