Description
Technical field
The present invention relates to a kind of towing machine, be specially the towing machine that a kind of elevator uses.
Background technology
Elevator traction machine is the power plant of elevator, also known as elevator main.Function is that conveying makes elevator run with transferring power.It is made up of electrical motor, drg, coupler, drop-gear box, traction sheave, frame and track adjusting wheel and attached handwheel etc.
Existing towing machine, elevator traction machine as disclosed in Chinese invention patent (notification number CN1141775C).The electromagnet of this towing machine and brake control lever are arranged on the outside of towing machine, and the brake wheel being acted on towing machine outer rotor by brake control lever produces braking force, thus braking towing machine.The deficiency of this invention is: 1) because the brake wheel of towing machine and traction sheave are positioned at the same side, and adjacent configuration, such brake area is very easy to the grease impact being subject to steel rope, thus causes the friction coefficient of brake area to reduce, and the normal operation of this elevator brings disastrous effect; 2) because drg is arranged on the outside of towing machine, the noise of drg directly transmits in outside, thus causes the noise of towing machine to increase, and the riding quality by directly having influence on elevator applied by such towing machine in machine-roomless lift; 3) in order to reduce noise be usually by between friction lining and brake wheel gap arrange very little, like this when because of brake control lever effect on the brake wheel, because the opening time of two brakings can not be consistent, so brake wheel may be caused to stressed Direction distortion, thus cause another brake control lever may contact with brake wheel, thus make the friction disc wear of another brake control lever, reduce the service life of brake control lever, and bring vibration and noise may to the operation of elevator; Simultaneously in order to ensure that brake wheel and brake control lever have enough rigidity to need the enough strong brake control lever of design and brake wheel, the cost of towing machine will be increased like this, and increase due to the inertia of brake wheel, increase the torque requirement of towing machine, thus increase the cost of towing machine further; 4) because brake control lever and electromagnet are arranged on the outside of towing machine, the oad of towing machine is caused to become large on the one hand, comprise the axial dimension of the needs of brake wheel, the height that electromagnet needs, affect the outward appearance of towing machine, this towing machine can not be applied on machine-roomless lift product substantially, causes the parts of towing machine to increase on the other hand, the processing capacity of parts increases, and the cost of towing machine increases; 5) because magnet steel is arranged on rotor, and brake surface is also positioned on rotor, so when brake control lever produces braking force to brake wheel, impact will be produced to magnet steel, such impact will directly have influence on the connection of magnet steel and rotor, thus magnet steel may be caused to come off from rotor, cause serious accident, run to elevator and bring serious impact.
