Worm Screw Jack Compact Structure

Worm Gear Reducer is a compact structure, high transmission ratio, Worm Screw Jack and under certain conditions with self-locking function of the transmission machinery, is one of the most commonly used reducer, of which, the hollow shaft spiral gear reducer Not only has the above characteristics, Worm Screw Jack but also easy to install, reasonable structure, more and more widely used. Hollow Shaft worm gear reducer in the worm gear reducer to add a helical gear reducer, the multi-stage reducer can obtain very low output speed, is the combination of helical gear grade and spiral gear level, which is more efficient than the pure single stage worm gear reducer. Worm Screw Jack and small vibration, low noise, low energy consumption.

Worm gear reducer in order to improve efficiency, generally used non-ferrous metal worm gear, worm is the use of hard steel, because it is sliding friction drive, Worm Screw Jack in the course of operation, it will produce higher heat, so that the reducer parts and seals between the thermal expansion of the difference, Worm Screw Jack so that in the coordination surface of the gap, and oil due to the temperature of the increase in dilute, easy to cause leakage. The main reasons are four points, one is the material collocation is reasonable, the second is the surface quality of the meshing friction surface, the third is the choice of lubricating oil, Worm Screw Jack the quantity is correct, the four is assembly quality and use environment.


The worm gear commonly uses the tin bronze, the mating worm material uses 45 steel to harden to the HRC45 155, also commonly used 40C: hardened HRC50 155, the worm grinder grinding to the roughness of the Rao 8FCM, the normal operation of the reducer, the worm is like a hardened "file", Worm Screw Jack and constantly file the worm gear, so that the worm gear. Generally speaking, this kind of wear is very slow, like a factory some reducer can use more than 10 years. If the wear speed is faster, it is necessary to consider whether the reducer selection is correct, whether there is overload operation, worm gear material, assembly quality or use of the environment and so on.

Generally occurs in the vertical installation of the reducer, mainly with the addition of lubricating oil and the choice of lubricating oil. Vertical installation, it is very easy to cause insufficient oil, when the reducer stops running, the motor and reducer transmission gear oil loss, the gear is not due to lubrication protection, start-up or operation process is not effective lubrication caused mechanical wear or even damage.

When the reducer fails, even if the gearbox is well sealed, the factory often finds that the gear oil in the reducer has been emulsified, bearing has rusted, corroded, damaged, this is because the reducer in the process of transport, gear oil from the heat after the formation of water condensation caused; Of course, and bearing quality, assembly process method is closely related.
