Description
Technical field
The present invention relates to a kind of traction machine, the traction machine that specially a kind of elevator is used.
Background technology
Elevator traction machine is the power-equipment of elevator, also known as elevator main.Function is that conveying transports elevator with transmission power
OK.It is made up of motor, brake, shaft coupling, reduction box, traction sheave, frame and directive wheel and attached handwheel etc..
Existing traction machine, the elevator traction machine as disclosed in Chinese invention patent (notification number CN1141775C).The traction
The electromagnet and brake arm of machine are arranged on the outside of traction machine, are acted on the braked wheel of traction machine outer rotor and produced by brake arm
Raw brake force, so as to brake traction machine.The deficiency of the invention is：1) due to braked wheel and the traction sheave of traction machine be located at it is same
Side, and be adjacent to, such brake area is highly susceptible to the grease influence of steel wire rope, so as to cause the friction of brake area
Coefficient is reduced, the influence of normal the bringing on a disaster property of operation of the elevator；2) because brake is arranged on the outside of traction machine, braking
The noise of device is directly in outside transmission, so as to cause the noise of traction machine to increase, such traction machine is applied in machine-roomless lift
The riding quality of elevator will be directly influenced；3) it is often that the gap between friction plate and braked wheel is set to reduce noise
It is very small, so when because brake arm effect on the brake wheel, due to two braking actuation times can not possibly be consistent, so can
Direction distortion of the braked wheel to stress can be caused, so as to cause another brake arm to be contacted with braked wheel, so that separately
The friction disc wear of one brake arm, reduces the service life of brake arm, and vibration may be brought to the operation of elevator and is made an uproar
Sound；Simultaneously in order to ensure that braked wheel and brake arm have enough rigidity to need to design sufficiently strong brake arm and braked wheel, so
The cost of traction machine will be increased, and because the inertia of braked wheel increases, increase the torque requirement of traction machine, so as to further increase
Plus the cost of traction machine；4) because brake arm and electromagnet are arranged on the outside of traction machine, the profile of traction machine is on the one hand caused
Become large-sized, including the axial dimension the need for braked wheel, the height that electromagnet needs, influence the outward appearance of traction machine, the traction
Machine can not possibly be applied on machine-roomless lift product substantially, on the other hand caused the parts of traction machine and increased, parts plus
Work amount increases, the cost increase of traction machine；5) because magnet steel is arranged on rotor, and braking surface also is located on rotor, so system
When swing arm produces brake force to braked wheel, will produce impact to magnet steel, such impact will directly influence magnet steel and rotor
Connection, so as to cause magnet steel to be come off from rotor, causes serious accident, and serious influence is brought to elevator operation.
The content of the invention
The technical problem to be solved in the present invention is：To overcome above mentioned problem to run more stable traction machine there is provided a kind of.
