Elevator lubrication and lubricant performance requirements for advanced technology
Mainly composed of various types of elevators vary, but typically
include eight components: traction systems, guidance systems, car, door
systems, weight balance system, electric drive systems, electrical
control system, security system.
The total lift into elevators and escalators into two categories. Mainly
composed of various types of elevators vary, but typically include
eight components: traction systems, guidance systems, car, door systems,
weight balance system, electric drive systems, electrical control
system, security system. Machinery
and elevators are mostly located at the top, including the motor and
control system, the motor rotation by gears or (and) pulleys, as the
chassis and power for up and down movement of heavy equipment. Operation of the motor control system and other operations, including
starting and braking control elevators, and security monitoring.
Elevator equipment in many parts need lubrication, mainly traction
gear box, rope, rails, hydraulic buffers, and other components of the
car door door.
For
toothed traction type elevator, which hoisting system reduction gear
box serves to reduce the output speed of the hoisting machine, to
increase the output torque. Traction system has a variety of reduction gear box structure, commonly used type worm, bevel and planetary gear type. Worm-type
turbines are mostly used traction machine wear and bronze worm using
surface carburizing steel, slide the worm gear tooth surface between the
large tooth contact time is longer, friction wear prominent. So, no matter what kind of worm gear, there is extreme pressure and anti-wear problems.
Similarly, the bevel gear and planetary gear-type traction machine also has extreme pressure anti-wear problems. In
addition, oil for traction machine should have good fluidity at low
temperatures, there must be a better oxidation stability and thermal
stability at high temperatures. Therefore,
there is a reduction gear box oil viscosity gear traction machine is
usually chosen for VG320 and VG460's worm gear oil, lubricating oil can
be used as such escalator chain lubrication. Antiwear
lubricating performance is greatly improved, the metal surface to form a
strong film, long adhered to the metal surface, effectively reducing
the friction between metals, so that the gear when starting to get good
lubrication Protective effect immediately. Gear lubricants with excellent water resistance, oxidation resistance
and has strong adhesion, can improve the gearbox (gear box) seal,
reducing permeability.
Hoisting
reducer gearbox oil, the general reduction gear box each elevator parts
and bearing temperature should be less than 60 ℃, the oil temperature
inside the enclosure should not exceed 85 ℃, different grades of oil
should be used in different types according to the elevator, the
function lubricants, and should pay attention to the amount of fuel, oil and oil spills.
