Hoist Driving device SC type construction lifter transmission mechanism is also called the elevator drive plate, is the core of elevator drive and safety device, by YZZl32M 4 special motor, a plane enveloping ring surface vortex rod reducer and for safety device components are installed on the same floor.
It installed in the elevator car trunk, composed of motor and speed reducer drive transmission power plant to small gear reducer output side, vertical rack and pinion and elevator meshing, drive the car up and running smoothly.For safety device with vertical rack and pinion engagement, once the motor brake failure and make the car skids, automatically open for safety device, car emergency brake immediately, to ensure the safety of the lifting machine running.
Compact mechanism design is reasonable, factory after running-in experiments.Different specifications are available in three drive and double drive type elevator.Also can provide users with a single motor reducer.
Hoist Driving device (single) : one, the main performance parameters of the motor rated power llkW, rated speed 1400 r/min, braking torque rating 120 n. m reducer (single) : 14 (16) ratio, 890 (1020) rated output torque N.m, rated speed 100 (87), the efficiency of 85% for safety device: brake load rating 30 kn, rated speed 1.2 m/s, braking distance is 0.15 ~ 1.40 m note: column gear reducer, the brackets data according to user requirements.
|11||90||1. Its starting and braking are both smooth and won't shock the machine too much.|
2. The frictions of brake is made of imported material.
3. We adopt special rotor design to reduce starting current and increase starting torque and strengthen starting ability in low voltage.
4. We also adopt cold rolled punching plate to decrease loss and increase efficiency. The whole structure is simple and the performance is reliable and safe.
Disc brake three-phase asynchronous motor is composed of fan-cooled three-phase asynchronous motor and DC disc brake two parts. Motor and brake coaxial assembly, small size, light weight, compact and reasonable structure, flexible and reliable braking, the motor for the lifting of special motor, starting current is small, starting torque, suitable for frequent start, braking and forward and reverse. Brakes refer to foreign similar product design, compared with the general brake has a brake, smooth and automatic tracking adjustment of the friction clearance function. Brake with the overall disc brake pads, so that the motor noise, vibration to a minimum, which has a safe, buffer, environmental protection and many other excellent performance, especially suitable for high-rise construction of the lift, can also be used for a variety of winch And other lifting machinery. Motor rated voltage 380V (440V), rated frequency 50Hz (60Hz); brake voltage is DC 195V; motor reference working system for the S3-25%, insulation class F; installation structure type IMB5.
According to foreign similar products to transform the design of new motor, the brake parts of the electromagnet, with the brake block wear, can be automatically tracked to adjust the distance between the armature. The motor from the brake gently, the impact of small mechanical equipment, and the structure is simple, easy to operate, safe and reliable performance, is a new generation of construction lifts and other lifting appliances ideal for special motor.
