Description
Technical field
The utility model belongs to technical field of motors, the shaft coupling being related on a kind of elevator traction machine.
Background technology
Elevator traction machine is the power-equipment of elevator, also known as elevator main.Function is that conveying transports elevator with passing power
Row, control elevator car are only stopped.It is by motor, brake, shaft coupling, reduction box, traction sheave, frame and directive wheel and affiliated disc
The compositions such as driver's wheel.Directive wheel is generally seated on the spandrel girder under frame or frame.Handwheel some is fixed on motor shaft,
Also have and usually hang over nearby on wall, be enclosed on again on motor shaft during use.
There are the following problems for existing elevator traction machine：1st, the brake of traditional elevator traction machine is draged by Electronic Control
Draw elevator car residing for machine and between the walls, dust debris are more, the debris particularly fallen at door-opened elevator, the control to elevator
Part has a great influence；2nd, the brake of traditional elevator traction machine does not have passive safety feature, occurs in abnormal conditions such as power-off
When, the danger fallen be present in elevator car；3rd, the brake of traditional elevator traction machine be all by being braked to the rotating shaft after deceleration,
Integral stop is realized, its rotating speed of the rotating shaft of deceleration is smaller, and braking effect is more obvious, still, when the rotating shaft at deceleration end is braked,
Larger to reduction box impact, the damage and impact to shaft coupling are larger；4th, the shaft coupling of traditional elevator traction machine does not have typically
Pooling feature, even if some shaft couplings have pooling feature, it, which is buffered, can not be directed to the actual conditions of elevator and buffer, i.e.
Ascending for elevator only stops and the lower whereabouts stopping time, and its impulsive force is different, and it is larger that lower whereabouts stop impulsive force, and is not easy to avoid, descending
It is smaller only to stop impulsive force, but is not allow for resilience, if there is resilience, the weightless sense to passenger is stronger, causes boarding uncomfortable；
5th, the reducer structure of traditional elevator traction machine is complicated, is typically realized by bevel gear, and its speed reducing ratio is obtained by repeatedly slowing down,
Sacrifice section transmission stationarity.
