Details of the traction machine

The elevator traction machine is the power equipment of the elevator, the elevator is also called the host.Function is the transmission and transfer of power to make the elevator running.It consists of motor, brake, clutch, gear box, traction wheel, rack and guide wheel and accessory handwheel etc..The guide wheel is generally installed on the bearing beam of the frame or the frame.Some handwheel is fixed on the motor shaft, there are usually hanging on the wall near the use, and then set on the motor shaft.

classification：

⑴Classification by means of reduction

①Gear traction machine:Driving force,The intermediate reducer transmission to the traction sheave of the traction machine,General for the 2.5m/s below the low speed lift.

②Gearless traction machine:Driving force,No intermediate reducer but directly transferred to the traction sheave of the traction machine,Generally used for more than 2.5m/s of high speed elevator and super high speed elevator.

③Flexible drive mechanism of traction machine.

⑵Classification by drive motor

①DC traction machine,It can be divided into DC gear traction machine and DC gearless machine.

②AC traction machine,It can be divided into toothed AC traction machine, AC gearless traction machine and permanent magnet machine.

⑶Classification by application 

①double speed elevator traction machine

②VVVF passanger elevator traction machine

③Grocery tractor

④machineroomless elevator traction machine

⑤vehicle elevator traction machine

⑷Classification by speed

①Low speed traction machine

②The speed of traction machine (fast traction machine)

③High speed traction machine

④Ultra high speed traction machine

⑸Classification by structure

①horizontal traction machine

②vertical traction machine

Working principle

The installation consists of traction machine in the engine room of a motor and a gear box, brakes, power traction drive.The traction rope connected with a car cabin

through the traction wheel is connected at one end of the counterweight.In order to make the wells in the elevator car and counterweight respectively along the guide shaft running without rubbing, traction machine is placed on the guide wheel to separate the two.The car and counterweight to gravity traction rope pressing friction on the traction wheel groove.In this way, the rotation of the motor drives the traction wheel to rotate, drive the rope, drag the car and the Remaking of relative motion.That is, the car is rising, the weight is falling; the weight is rising, and the car is falling.So, the car is in the well track along the guide rail, under the reciprocating operation, the elevator to carry out the vertical transport task.
